New Ideas

SiteCover

For the first time in history large scale new-build can be produced under factory-like conditions. SiteCover is large scale weather protection structures, strong enough to withstand all weather conditions, and to carry heavy duty cranes in the roof. Our structure has a possible free span of 87 m. A maximum height of 30 m (under crane hook) and it is fully flexible in regards to the number and positions of cranes in the roof. Cranes have a capacity of 12t each and even 22t lifting together

Le liber

The aim of our project is to design a building consisting of convertible trays and a stabilization core in which the technical rooms would be grouped. We therefore want to have the largest free surface available in order to be able to move modules, which can be rooms, meeting rooms... at our discretion. To do this, we want to create a type of module that can accommodate kitchens, toilets, bathrooms and distributions according to needs. They will be the supporting posts of our building and will make as much free space as possible available for relaxation areas and bedrooms.

C

Structural system with wooden elements. Is a structural system that consists in a C shaped main profile, which is the base of the building structure. This C shape profile function as the main columns and beams to make it a stable structural system and are connected with each other with C profile connectors which can vary the form of the building. The profiles have a dove tail connection that supports the secondary elements. The other constructive elements can be added to the C profiles, like secondary beams (are stacked to the main beams), façade elements and also the floor slabs can be supported by the main beams. The main characteristic of the structure is that wood panels can be slided in to create the floor slabs of the building and façade. Making the construction process clean, easy and fast to assemble. The facade can be made with different materials such as aluminum, wooden, glass, metal panels to recreate building cover. This system allows the connections of the structural elements through a clipping system to vary the distance between each profile to make the space bigger, also higher. Height can be two, three or how many times the costumer desires. This system offers customers different benefits; easy and fast to assemble, customizable, modular, easy to transport, ecological.

Woodcomb

Woodcomb is a modular construction method that provides simple, fast and efficient structures using Metsa wood products by taking into consideration the off-site production and the ease of transportation of materials. Each module is designed as a hexagon and provides 17 square meters of space with 3 meter floor height. Every hexagon is designed to have its own structural integrity due to its panels acting as shear walls. These shear wall panels are further more connected with triangular beams on every floor level to balance and distribute forces within every Woodcomb module. Various layouts can be achieved by taking into consideration of the beam directions. In this example 15 units are connected on 3 storeys providing workshop, office and dwelling units connected with a courtyard.

Modular grid structure

Using Kerto LVL as a major building material we introduce a modular laser cut grid structure that is efficient in production. The main purpose of employing this technology is for its strong foundation characteristics of crack and sagging resistance. Kerto material has a possibility to span longer than standard framing system and allows us to build a large surface construction. Team: Mahmoud Abdel Mohsen Maria Eero Max Müh Pavel Furtsev

Post and Beam system combined with modular (volumetric) system

Easy and fast on-site assembly due to the high prefabrication degree and the railing system. The railing system allows fast assembly where cranes are used to lift and position the volumes. The railing system is an interface between the volumetric units and the post and beam structure. The volumetric part of interface is the cant of the floor. The floor is made of kerto elements. The post and beam part of the railing interface is also mede of kerto elements.

human parking

The frontline of architecture today is not just a housing crisis; it is a crisis of the home. Over the last two decades our patterns of life have changed so profoundly that architecture has struggled to keep apace. Gender roles in society and power roles in the family have changed – affecting the size and formation of our households. Cheap international travel and the European Union have made short and medium-term relocation accessible, and most of us will live in at least two cities besides our birthplace before we are 25 (whether as a student for a few years, or on a business contract for a few months). Perhaps more importantly than budget airlines, the rise in ubiquitous mobile telephony has facilitated and accelerated this mass migration and movement. So modern city dwelling can be fast-changing, and the needs are quite different then what we're used to. But there is still plenty of places for making new habitats on the same roads - only we're using it for storing cars. The technology of self-driving taxi and new forms of mass transport will leave these spaces abandoned soon - so maybe we could use them to start solving our new citizens' problems. /With Eszter Gall

VII House

Urban development and population growth in a city will be a new challenge for human being in the future. Natural resources degradation, limited and exploited area push people to think not only how to live but also how to survive. VII House is a wooden concept to answer these challenges. With minimum 3 level structure and can be added to a bigger scale, it has 2 different type which are primary structure and additional structure. Primary structure, In the ground floor level, spaces are designed to be more open for socializing, entertainment, workshop and business purpose with toilet on it. Intermediate floor, spaces are designed to be semi-private where occupant have their living room, bed room and private balcony. Other people could also access to 3nd floor through 2nd floor where inner agricultural space built for. In 3rd floor, occupant and neighbour could plant their own food, rain water collection as well as for the view. Additional structure has mostly the same features with primary structure does with a kitchen in intermediate floor and wider spaces on the ground floor. When primary and additional structure combined, there will be a triangular platform provided in the 2nd floor to connect two buildings. So that, it is accessible and enhancing efficiency by reducing construction cost. Team Member : Ilmian Sujatmiko & Reza Hafizh

Modular Star

The proposal is situated on a corner plot in Glasgow’s West End. It has a commercial ground floor, high-density apartments above and communal eating and living areas on the top floor. The main structure is formed by a series of ‘star’ supports constructed using Kerto LVL Q panels.

INFILL CITY

Inner cities are becoming over saturated with high-end offices and hotels made from concrete substructures and lavish material finishes. People are being pushed out and the ecosystem of live-work and play within the inner city context is becoming extinct. Instead cities are becoming more and more commuter orientated. Infill City is a concept which is based on modular construction techniques using timber, open-sourced products provided by Metsa Wood. By utilising modular timber construction we can infill vacant spaces within the city and create collaborative living environments for inner city dwellers. The core construction would be based on a platform construction whereby elements would be pre-made off site on a 5 X 5 meter grid system which would allow for micro apartments with shared amenities with external terraced spaces between each level. XL Kerto LVL Q wall elements would be utilised, with RIPA Floor elements for high load bearing capacities meaning multi storey infills could be achieved in dense inner city environments. The external walls would be clad in site specific materials such as glazed brick tiles to match the appearances of adjacent buildings.

ITEM 11

''ITEM 11'' is an introduction of simple, rectangular Kerto LVL elements that are sized in various transportable dimensions and can easily be mounted once on site without challenges. From Buea to Bamenda, Helsinki to Hamburg, Virginia to Vancouver, this design proposal is a perfect response to address the shortages of ''takeaway'' restaurants on the highway. The timber construction is sustainable, simple and fast to build. The restaurant is designed on a footprint of 80 m² (14.42 m x 5.40 m) and can accommodate 30 guests at any given time. Outdoor spaces provide additional sitting possibilities. The eco-friendly design is characterized by two modular systems dividing the ground and upper floors respectively.

Thermowood panel cladding

Thermo wood panel cladding or TPC is designed with wooden bricks (19mm thick) for the exterior and (16mm thick) for the interior. The components of this product consist of smaller units of thermo wood that are placed in bricks and form the desired panel. Installation is very easy and has a high speed and unique beauty.Due to wood trimmation, it is very suitable for the exterior and has a very high resistance to weather conditions.

Top home° hollow rafter

The engineered rafter was a key component for the top home° prototype, a Passivhaus, that can be build without heavy equipment on site - so all elements need to be very lightweight. Depending on the climate, Passivhaus u-values require at least 400mm of roof insulation. Rafters become unnecessarily heavy and break the heavy insulation layer. A prefabricated hollow rafter element has the following advantages versus a solid wood rafter or a simple LVL beam: + elements can be broken down and transported easily, joined on site. This is especially useful for long spans, hard to reach building sites and other scenarios, where a crane is expensive or impossible, e.g. urban densification.+ increased stiffness and load rating for the same material use. + a single rafter appears solid, yet offers hidden internal space for cables, plumbing, HVAC services. All of these can be put in place while the rafter is still on the ground (safer work environment!). As one side is left open, all the services can be laid in, there is no need to pull cables and pipes (increased speed!). + the remaining hollow space is filled with insulation, e.g. blow-in cellulose fiber. Minimum width is 87mm (21mm panel+45mm T-Stud+21mm panel). T-Studs may be stacked, no maximum width. The elements for a rafter are fabricated with a CNC machine, preassembled in a jig and finished on site.

Structural Elements with LVL KERTO®-S+Q - From Bridge to Building Construction Design

Structural Elements with LVL KERTO®-S+Q - From Bridge to Building Construction Design by L. Haefner, Dr.-Ing. IBH-SE: L+T+R, Sophie-Charlottenstr. 9-10, 14059 BERLIN Email: IBH.SELT@gmx.info 1. Overview of Pedestrian and Bike Bridge with LVL Kerto-S/-Q The bridge is a 4-span construction (Graphic 1) with the first span of a load bearing roof section above the walkway and 3-span T-beam construction with an open walkway. The bridge was built with modern wood composite of Kerto®, laminated veneer lumber (LVL) with available large boards bonded together. Steel elements are frames, truss girder and plate connections. The first, covered span is the technical remarkable part with a weak torsion folded plate, built with LVL of type Kerto-Q wood composite boards and steel bracing truss girder underneath. There is load transfer from walkway by the hanger (vertical beam) into the timber roof and from there to steel frame at two supports. Bridge bearings are placed on a concrete pile wall and on middle pier (Graphic 2). For the uncovered part of this modern bridge was used high-strength material of wood composite Kerto-Q with large boards and Kerto-S beams for continuous 3-span walkway. With the advantage of large Kerto-Q boards and overlapping as a 3-span continuous beam has been build (Graphic 3). 2. Building Construction of a Rooftop at Berlin + Tall Timber Building With the experience of a bridge follows heightening of an existing building as rooftop with the advantage of construction material Kerto and foremost pre-fabrication. There are pre-fabricated walls with Kerto-Q boards as airtight construction. The rib-slab elements are covered with special concrete layer and connected as Timber-Concrete-Composite (TCC) for fire protection. This construction method results in an assembly with a high noise control structural element. Furthermore, there are research results here presented for tall Timber Building design with façade optimization against wind and vibration loading. 3. Advantage of LVL Kerto-S/Q and Construction Details There are the dimension and material data with properties such as • Large boards with width * length = 1.80m * 23m, and various thickness. • High strength timber material, orthotropic timber properties. • Transfers strength capabilities for Kerto-Q for load transfer, With basic “pressure bonding” and/or “screw-pressure bonding” large pre-fabricated structural wall and plate elements can be produced. The required bracing of any building can be solved by Kerto-S or much better as bearing walls with Kerto-Q (Graphic 4). Also, for our research activity some essential references and literature are following presented. Berlin, Dec. 31st, 2017 -2-  References: Barber, D.

New baloon Kerto

This new and old system is designed to solve the external and internal load-bearing walls that will make up a tall building. Unlike the platform system, this, the baloon considers the walls of all levels as a single structural piece, formed by continuous vertical pillars, in this case Kerto beams. To give rigidity and stability to the walls, the studs are crossed on both fronts with Kerto beams separated from each other. (The calculator will determine if it is necessary to place steel crosses). The intermediate floors are created by placing the horizontal beams connected to their corresponding studs and taking advantage of their support on the horizontal beams of the walls. This system allows the passage of pipes in horizontal and vertical position. This is a marked difference with the CLT system. Free spaces between studs and cross beams can be filled with materials such as: concrete, prepared earth, cellulose, gypsum and straw, etc. A system like this will consume less wood compared to the CLT.

Forever Straigth

We all know that usually windows and doors made of natural wood with the passage of time are sometimes destabilized by drying the pieces and this produces the ""fall"" of the sheet, both window and door. On the other hand if the product was created with a main frame and internally it was filled with a natural wood board, between both different dilatations are produced, producing cracks in the board. In products with many years and mainly those that are exposed to many daily hours of sun, you can appreciate all these defects. Therefore I thought that a definitive solution to avoid these deformations and cracks, we should use whole plates similar to plywood. Taking a plate as the central and glueing to this other plates in front and behind, in order to create a design with relief, then we will obtain a very stable product and that will never deform over the years. Consideration should be given to the adhesives to be used that must be resistant to moisture and that the products are not very exposed to rain, at least they should be behind the facade within the thickness of the walls. They should be painted with high quality wood protectors.

Piece, Component, Artifact.

Prefabrication emerges as a high control alternative for complex processes, such as wood, in which design and control are fundamental for a good final result. In addition, it generates other advantages such as shorter construction time, the lightness of the pieces for transport and lifting and a lower cost to be able to work with smaller, standardized and easily acquired pieces. Under this principle, a set of 9 panels is developed that allow the integration of different shapes and solutions, from a vertical framework that is inserted into a stereometric grid of beams and pillars of laminated wood. The solution is finally filled with cellulose designed as thermal and acoustic insulation. From this modulation, 4 components are created, each corresponding to a department, following simple formal operations of addition and volumetric subtraction. The theoretical volume of each department was defined according to the formal variations to adapt laterally and vertically between them, developing together an empty intermediate space for the double-height projection of the courtyard of the lower department. Finally, and from the 4 components, the artifact is formed, which can grow in width and height to adapt to the needs and the landscape that will lodge it.

Plywood Stud

We all know that natural wood studs are not 100% straight and, sometimes, those that are very straight over time can deform. The best type of studs are those that are made with the finger joint technique, but this is too expensive. If we use strips of plywood and glue them, we can obtain an excellent stud. In the attachment, I am showing how to do it.

BOX BEAM AND BOX POST

Box Beam and box Post is a system for roof and floor elements for longer spans. Based on Conzett’s design, these elements are based on Kerto S & Kerto Q LVL loadbearing components. We used these elements for the construction of Pratgraussals’s Event hall, the length of the span is 24 meters. The property of these composite elements is that the section is divided into intermediate flange parts (KERTO-S) with two outer thin web part (KERTO-Q). The section of the box beam is divided into two outer Kerto-Q web of 51 mm thickness each and two intermediate Kerto-S layer of 75 mm thickness each. The section of the box post is divided into two outer Kerto-Q web of 45 mm thickness each and four intermediate Kerto-S layer of 75 mm thickness each. All the layers are connected with bolts. For our project of Pratgraussals’s event hall, one advantage of the hollow sections in contrast of I sections was a much better torsional stiffness, which is good for avoiding lateral torsional buckling specially during the transitional phase of lifting.

Plywood strips for Arches

This element is composed by glued plywood strips in a shape like canes. It is thougth to resolve dome and vaults. In many countires it is comon to build using all kind of canes or bamboo. Each cane work no exactly like one an other, and a big problem are conections between vertical and horizontal canes, because are tigth with wire or threads. When canes abosorb or desorb humiddity tis dimensions changes, so concetion move and desestibilizate. That are some of the problem I would like to solution using a standar plywood strip. Using the gluelam technique I can create curve strips as the canes are, but in this case all with the same shape, leting it me to do an excellent work. Another advantaje, is that conection will be able to be perfect, because it will be possible to glue and screw them, geting for that a perfect union between vertical and horizontal elements.

Cafe and Exhibition Space in Paenu, Estonia

The project name M3 stems from 3 main modular elements that make up the building structure. It is a pilot project proposal in Paenu, Estonia, in line with Metsaewood birch plywood mill in the city. The 3 main modular elements are M1, M2, & M3, with M1 having a trapezoidal shape, M2 rectangular shape and M3 having a rectangular form inclined at 45 degrees, hence cantilevered. The combination of these 3 modules form the design structure having a total surface area of 70 m2. The modular elements are sized to accomodate easy transportation. The construction is simple, easy and quick. The project with a compact configuration comprises of a Cafe on the Ground Floor and an Exhibition Space on the Upper Floor. The Cafe provides space where visitors can have a little break from the hustle and bustle of work and city life. The design of the Cafe with its retractable folding doors provides a welcoming ambience especially during the summer periods. The Exhibition Space displays different types of wood samples and literature to inform the public on the importance of wood as a construction material.

Modular floor

How to create universal modules for an apartment building? So that with a minimum number of modules there was a maximum number of variants of apartment layouts. This problem is very urgent now. The solution to this problem will allow building efficiently and quickly. There may be many solutions to this issue. A good material for solving this problem are wooden structures. Since the tree is very light and environmentally friendly. I propose one of the options for solving modules for the construction of multi-apartment houses. The idea is to divide the floor of a apartment building into individual components (modules). Such components can be manufactured at the factory. Then quickly assemble the floor of the apartment house from these components. Two main modules are created: module 1 and module 2. Plus two additional modules: module 3 (staircase), module 4 (staircase with elevator). And plus module 5 (corridor overlap). Ready-made modules are brought to the construction site where the floors of the apartment building are collected from them. You can use modules for both the construction of new apartment buildings and for the superstructure on top of existing houses. Modules are manufactured from Kerto LVL products with thickness 51mm, 57mm, 75mm. Structural base - columns, beams and overlapping. From the modules you can collect different versions of floors. Modules are manufactured at the factory and ready to be brought to the construction site. At the construction site the modules are joined together by means of connecting parts. Where there are spaces without walls and overlapping additional walls and overlapping are added at the construction site. Also additional walls and overlapping can be added at the factory. Holes for engineering communications and ventilation shafts are made in modules according to the planning solutions of apartments. Module 1, module 2, module 3, module 4 do not change. Only the module 5 changes, depending on the length of the corridor and the docking of other modules. Fastening of modules to each other can occur in various ways: with the help of connecting metallic elements; with the help of protruding structural elements; with the help of special adhesives.

SafeCube

SafeCube is a solution to emergency relocation after a storm or other natural disatser. We choose to give the simplest answer, SafeCube is delivered as a lego kit in a maritim container. every parts are light enough to be carried by 2 people, without using a mechanical crane. You don't need electricity, You'll only need a hammer and wrenches.

Kerto Ski

Sliding foundation is a modular foundation adapted to light buildings that needs to be easily moved to a different place. It can be used in harsh environments as deserted zones, where it can be filled in with sand to assure the building stability to wind efforts. It is prefabricated with 3 horizontal pieces in Kerto S (machined to retrieve a ski form), overlapping 2 columns in Kerto Q. The columns are 0.50m height to allow the natural ventilation of the slab. All the elements are glued and screwed. A metallic plate is screwed to the Kerto Ski to assure timber protection and sliding comfort. A couple of sliding foundations at a distance of 3m can support a dead load of 100 daN/m² and a live load of 150 daN/m². A Kerto Q slab (75mm thick) can be used for a 3m-span flooring. The total amount of Kerto needed for the couple of sliding foundations and the slab is 1.5m3. The couple of sliding foundations costs 2k€. The building on the sliding foundations can be a light beams and posts twin elements folded-out for an easy transport and a quick on-site assembly.

KERT'EAU - SEA KERTO

Our building concept aims at building large autonomous and floating neighbourhood size developments in coastal and riverside areas. Floating buildings are made of reinforced concrete hulls with water ballast on top of which are superimposed three levels of constructions: one technical level under water line; one working and living level above; one green gardening and farming at rooftop level. Concrete hulls are chosen for durability and maintenance purposes as well as cladding and roofing materials which should sustain very harsh marine conditions. 3D modules and building kits are prefabricated in mobile and industrial facilities such as large factory ships. BIM process would be fully implemented in building design and fabrication of building kits. Say one dwelling is made of 4 3D modules then one factory ship of only 4000 units may potentially prefabricate and carry all 1400 3D modules necessary to build a 350 apartments development. 3D modules are craned off the factory ship directly on concrete hulls and connected to each other in order to make housing buildings. 3D modules structure is made exclusively of Kerto panels for walls, floor and roof as well as Kerto posts and beams. These novel Kerto modules dimensions are: 3m large, 9m long and 2.7m high. Kerto module envelope is covered with rigid fire resistant thermal materials. And waterproofed with ventilated cladding panels and roofing material. Contact: Team 2 Hackathon Nantes: Rémi Thépaut Mathilde Godard Floris Marchais Christophe Henry

Plywood Light Posts (PLP)

The P L P (Plywood Light Posts) is necessary to avoid the consumption of light poles made of steel and concrete. On the other hand, I try to explain that with the same amount of wood from a natural post it would be possible to make two posts of plywood, The posts can be made in different shapes of section, hexagonal, octagonal, square, etc. It will be necessary to think about protecting the outer side of the posts, either with paint or a thin layer of recycled plastic, or steel.

Beam-Post

By using Kerto it has enabled me to innovate further and imagine a girder post prototype and other essential structure pieces. I use crosslap joints and spigot joints for the recovery of strengths and constraints, both vertical and horizontal, fastened by rivets-roofing grommet designed and made in HDPE in our workshop, calibrated by digital throwing.

Sewn Structure

In the Andean countries there is a millennial construction tradition called Quincha. This technique consists of interweaving canes into a vertical frame and then applying a mixture of earth and straw.This system is still used today, not only in Peru but throughout the world (there are many people who are rebuilding with ancestral techniques). I propose MetsaWood to offer to the market strips of plywood because it can normalize this constructive system. Strips are not nailed or glued, they are kept in the position that one leaves them by the tension to which they are submitted. They must have a separation between them so that the mixture of earth and straw cross from side to side. The application of the mixture is very easy. It is made by hand. It should be allowed to dry sufficiently until all the natural drying cracks occur. Then proceed to apply a plaster with finer texture. Another option of this sewn structure system is to leave the strips in sight, as an aesthetic option. If you want a wider strip, we will have to opt for a plwood thin enough to allow interlacing (this is also an aesthetic option).

Rib Beams

The Rib Beam is based in the concept of tensioned wood, in this case using strips of plywood. This beam has two advantages for its design: 1) floor included 2) aesthetics. The body of the beam is formed by three principal sectors: the superior zone conformed by a floor sector ( 60 cm wide) and two lateral cavities where the plywood strips are inserted. This zone works to compression. The inferior zone is compossed by one beam with a cavity to receive the strips and this is working to traction. The third sector is compossed by the tensioned strips and conects the superior and inferior sectors. The tensioned strips are in an “alive” situation taking profit of that, and giving more resistance to the beam. These beams already come with a section of floor formed with Plywood and are ready to leave the floor closed. It has a joining system to join to each other, to then screw to give unity to the floor structure.

Arched Kerto Beams

The concept arises from the idea of arching a beam of the Kerto type, like an bow in a tense position and using this situation to solve those engineering challenges to overcome big lights or heights. When arched beams are built from a mold, these beams are not working with tension that works a tensed bow. It is proposed to use the tensioned Kerto beams by bending them as a wooden bridge support. In this example the support structure is formed by a pair of 3 arched and crossed Kerto beams at their highest points. From the 9 produced crosses will be hung steel tendons to hang the wooden bridge. The structure of the bridge would be supported in the central area of the bridge length. It would also be possible to construct a wooden bridge that rests on a group of arched beams of Kerto as shown in the PDF. I suggest using the resistance of the tensile beams to use them to solve high and slender structures such as, for example, building tall buildings, as in the image. In all cases, Kerto beams should be protected with special weathering products and paints.

Kerto Brick

Kerto brick would be massive wooden brick, which could be handled and assembled manually. The production is simple, there is only one type of brick to be produced. All the main structures can be constructed with these bricks.

Wooden Windmill Tower

This wood mill tower is an ecological tower for windmill instead of steel. The tower is a truncated cone subdivided into three parts of 33 m aprox. Each part would be made with a vertical stud of Kerto beams. All studs would be attached, glued and screwed together. It is suggested the base of the tower of 4 m and the top of 3 m. The thickness of the tower wall would be an average of 18 cm. The same criterion of anchoring and leveling used for steel towers would apply to this wooden tower. The wood tower must be protected with oils to avoid moisture absorption, and must be covered with geotextile mesh and acrylic paint to be completely waterproof.

Open Source Wood- Flying Houses

In the current world, the environment and climatic conditions are becoming one of the most important problems of the architect, urban architecture and scientists. So designing of Houses that can be flying and landing in a new environment is essential . It means finding a new place new climate new landscape and new condition of life in the shortest time without any kind of moving, discharging and harm to home appliances and furnishings .

Vault Ply

The vault ply is an element made with plywood. It consists of a piece of 60 cm by 120 cm of 12.5 cm of thickness and the view faces have the fibers parallel to the axis of the vault, in this way it is easier the arching of the piece. In order to achieve bigger surfaces to the compression will be necessary to apply two layer of pieces. I suggest that the layer below the boveda and its upper side contain two layers of Vault Ply glued to each other in the parallel orientation to the axis with finger joint system. A second layer also serves to complete the assembly of the pieces. All are superimposed and crossed. That way there is a single layer glued and screwed. Between both layers there will be a batten cross frame (as it appears in the scheme) The whole of the lower layer and the upper and the core with the batten, results in a unique body and working to the compression and thus work like a real vault. Its core allows the circulation of air and it is recommended in times of heat to take advantage of its internal ventilation and to remove the heat by the upper ridge. Reinforced brick vaults were very common in the last century, using steel and portland cement, all materials with CO2 footprint. And in this century it is very common the realization of arched beams on which are supported elements that do not necessarily work to the compression. With my proposal I intend to simplify a bit the resolution of vaults without the need for special beams. I `m developing another ""egg shell"", which has inspired many builders. Obviously this wooden vault should be covered with all necessary precautions against the environment.

WAVE! floor system

Composite decking with a negative embodied carbon, and optimum structural, thermal and acoustic performance. It is made of a curved Kerto-Q panel strengthened with Kerto-S rib beams and a rammed earth topping. It allows long spans making it suitable for office and commercial buildings, and does not require temporary propping. Its light roof version allows up to 20m spans and can be easily single-curved across waves. The wavy shape of the ceiling and the acoustic chambers provided to absorb the sound waves enhance the acoustic performance of the system.

The One-Piece Cross

The One-Piece Cross is a structural element made up of whole pieces of plywood whose function is to join crosses of vertical structures with horizontal or inclined to each other. In a structural design such as the attachment, consisting of vertical elements crossed with horizontal for the execution of a vault, it is much better to have an entire cross to solve the crossing compared to a cut and intersected crossing. On the other hand it is in those meetings where tensions are greater and that is why it is important that there is an entire element. It is advisable that the joints of all the elements are with finger-joint system. In the end it will be necessary to cover the whole structure with elements resistant to external agents.

Plywood Plank Floor

The floor of Plywood Planks consists of joining pieces of plywood. Its dimensions could be of 20 cm of width by 120 cm of length and a thickness of 1.25 cm. Sometimes carpenters cut similar pieces and join them without any joining system and nail them on the face. In this case, the union will be made with tongue and groove system, for which it will have two sides with tongue (one for the length and the other for the width) and the other two sides with groove. To keep the piece fixed, it will be nailed as in the traditional table deck system, so that nails will not be seen (as shown in the file). A perfect thickness should be made so that there are no unevennesses. For more perfection of finish can be polished the whole floor. After that would be possible to make a finish with oil or wahtever product for wood floor.

Plywood Shingle

The plywood shingles are made with normal plywood or treated plywood. The system to cover the roofs with plywood shingles is similar to the traditional roof of wooden shingles. But this system has the benefit of being able to normalize its size by not having the natural problems of a natural tile. We are in a system that allows all kinds of size and shape desired.  The plywood wood by its composition is very stable in the face of temperature changes and will not bend as much as a natural tile and the same will not crack like a natural tile. The plywood shingle should be treated to stabilize it due to changes in humidity. It should also be treated to avoid fungi. If you do not have plywood treated I suggest that you try the following way: 1) Total immersion of the shingle for 24 hours in a solution of copper sulphate. 2) Natural drying. 3) Total immersion of the shingle in a solution of burned oil and diesel oil and remove it immediately. 4) Natural drying. 5) Total immersion of the shingle in protective paint for wood for 1 hour. 6) Let it dry naturally. After placing the shingle on the roof, paint with a wooden protector hand. A treatment of this way allows a duration of 5 years without having to paint again. The plywood shingle has a very important breathing system which allows air to circulate below the shingle to avoid areas of moisture stored there below. For that a series of grooves will be made which are expressed in the attached file. These grooves should be done before proceeding with your treatment.

Plywood Box System

The Plywood Box System consists of an element made with plywood. It is ligth an easy to work just using the human force. A box of four walls is made so that it acts as a pillar on a wall or beam on a roof. They are joined together by a tongue and groove system and should be screwed into their joints. It is planned for the construction of houses of one or two levels. The pillars are made up of two vertical studs and two side covers. Each pillar box could have covers 20 cm wide by 240 cm high and the desired thickness (10, 12, 15, ...). After having solved the foundation and fixed the sole plate, the pillar box is fixed with screws or nails. In the lower area of ​​the pillar box the covers go lower than the studs and these overlap in the sole plate, and thus allows the connection. Similarly, a beam bond is placed at the top of the pillar box. As for the roof box the element is very similar to the previous one, two beams of the type Kerto but quite thin, will work to the traction, covered with two covers, one above and another underneath. They are joined together by the tongue and groove system. Both the walls and the roof must be covered with the standard criteria of any wooden dwelling.

Plywood Link

It consists of a piece of plywood 10 cm wide by 120 cm long and varied thickness. In its extremities this will have finger joint. It will be the component of straight beams or curved beams. It will be used to create beams of the laminated type but without the need of special presses, that is to say that the people can make them in its own workshop or place of work. This Plywood Link has to be glued and screwed to ensure excellent adhesion with the other elements. If it is a question of constructing a straight beam, then an element 1 inch in thickness can be used and the fibers of the viewed facing should go in the long direction of the beam. In case of constructing a curved beam, a thinner plywood of half an inch is recommended, whose faces have the fiber perpendicular to the direction of the beam. In this case the element can be easily undulated without breaking. Considering these concepts will be possible to construct buildings without necessity of CLT, especially those that contain curved walls and intermediate floors. Even build mensulated structures, which can be strengthened with steel in the areas of high tensile stress. All this will help us to consider the use of wood in places and designs unimaginable. In the same way we can consider this element for the construction of new wooden ships. Reusing wood to build large transatlantic ships will be an ecological solution to the use of steel in modern ships. It will be possible to construct the shell of the ships without needing structural ribs because crossed the planes formed by the Plywood Links (similar to the CLT) will obtain a very firm board and with the desired undulation. I name this as Crossed Plywood Link Timber. In order to realize these undulated planes one must have a formwork with the desired shape, on which one begins to work. Beyond this approach in nautical science, I consider that naval engineers should consider everything related to structure and considerations to be taken in the face of water hazards, such as covering the part of the submerged ship with steel, etc.

Posttensioned Laminated Beam

Generally a wood beam is calculated by the own resistances of the wood in terms of traction and compression. So the result can be a long beam and very wide, which means a lot of wood expenditure. Thinking that steel has a lot more resistance to traction is that I have thought of helping the long beams with steel inside. With the same criterion as the post-beam system of concrete beams, I consider that the traction of the wood can be strengthened. Considering the increase of resistance by post-tensioning it will be possible to construct smaller beams in terms of their width or to overcome longer lights in architect's works and also to consider them to build bridges of civil work. In order to make these beams, it will be necessary to calculate the path of the tendons and to engrave the cavity through which they pass so that by joining two beams the circular space is formed for their operation.

Reinforced Plywood Timber

This is a timber element composed by plywood and it is reinforced for plywood pieces. It works for walls, intermediate floors and roofs. Like in CLT, this RPT has structure in itself and it doesn't need a principal structure. In a simple example it has two plywood layers and in between it has a zig zag of longitudinal plywood pieces working as studs in wood framing or beams in an intermediate floor. The plywood layers (1 inch) are made of two layers of 1/2 "" plywood. The thick of these layers and the internal zig zag will depend of the structural requirements. The wall element would have the standard international hight (8 f), but for intermadiate floorings there should be longer plywoods. This RPT has the advantage that can be filled with insulation. For the exteriors it'll be necessary to apply all the technical specifications like in any wooden building.

Laminated Wood Corrugated Sheet Roof

This Laminated Wood Corrugated Sheet Roof is an corrugated plywood especially for roof. At the superior face, it will be covered with a galvanized sheet. I have been thinking of this idea after we got a tornado in Uruguay, because galvanized sheet roof were pull out from the roofs. One of the reasons was because those are so thin. Then I thought that sheet roof should be thicker. At the same time this corrugated plywood gains in tensile strength and becomes more self-supporting. Thanks to this, less roof structure is needed. It also gains in beauty, because most people like to see a wooden sheet than an iron one. And also it does not transpire. I recognize that a specific technology is needed to make this type of sheet

Grid Wood System

I name my invention the Grid Wood System. This element is made with plywood strips, which are placed verticaly and horizontaly, shaping a grid. The amount of vertical strips in one meter depends of the load over them. The horizontal ones are just to keep a distance. By using this system it will be possible to incorporate into the walls diferent materials as prepared earth or concrete, or just to aplly sheet rock. This idea came to me seeing the CLT system which is 100 % wood, thinking about a ligther system is the reason why I invented this crossed strip timber. CLT spends too much wood. At the same time I thougth that adobe earth buildings are millenial and it would be interesting that it would exist a system that allows the use of earth again like an excellent ecological material, but used in a new technique. So I consider that this Grid wood system fits using prepared earth. The other reason was because there are people that still don´t like wood, so they can fill the Grid Wood with concrete. So I have developed a system for walls, roof and intermediate floor. It can be created like panels or as the whole area of the wall or roof. In all cases top beams over the walls will be necessary, in which will be done all the conections with intermediate floorings. Building with this system will allow to build quicker compared with the wood framing system.

Antisucking plywood

This "antisucking plywood" is a plywood that connects the structure of the walls with that of the roof at the same time in a single product. This plywood is composed of the same materials as a common plywood, the difference is in its molding because it is not flat but is adapted to the angles between the ceilings and walls. Usually plywood is used to stiffen light wood framing structures. And the stiffening structures of the walls and roof are cut by the same elements of wood and finished of joining them with metallic connectors. My idea arises from the need to place a plywood that structurally joins the walls with the roof. Strong winds and tornadoes produce suction on the structures of the roofs and walls and often the results are very damaging. So if we put together the resistance of this type of plywood and the metallic connectors we will have more resistance against strong and tornado winds. The antisucking plywood can be used to joint wall with wall in the corner. This can be used to paint wall with wall in the external corners, or external walls with internal walls. Therefore it will be necessary to manufacture plywoods folded in 90 degrees and with other grades for ceilings, 20, 25, 30, 35 and 45 degrees.
