Kerto LVL connection wedge v2.0


This connection wedge is a redesign of standard wedge that is used in different wooden constructions. LVL sandwich structure requires design of mechanicaly simple solution that is quite simple to make in a mill skale and still is providing strength and flexibilty for large panels (4.2mx15m). (without inner milling because it can cause splitting) The wedge 2.0 is a wedge with inner cutting, that provides strength in comparisons with simple wedge that is quite flexible. Combination of "male" and "female" wedges (see on figure or on drawing) provides strength in longitudional direction and as well decrease effects of structural differences of each wedge (that looks like a tooth).

Key benefit

Provides structural stability with the required amount of flexibility

Material list

Metsa Kerto LVL, gluing of connection is also recommended. In somes metalware can be used for construction strengthening.
