Wooden e.g. solid wooden, wall construction system for e.g. house, has beams with lateral projection whose edges are constituted by extension of lateral and lower surfaces, where base of projection does not project quarter of width of beam

摘要

The system has different types of beams e.g. angle reverser beams (100, 103), angle beams (101, 104) and a standard beam (102) stacked one above other using upper surfaces and complementary lower surfaces, where the beams have same sections. The beams have a lateral projection (19) whose edges are constituted by an extension of an outer lateral surface and by a returning lower surface inclined with respect to the lateral surface. The base of the projection does not project the quarter of width of the beam. The beam (102) is provided at a same side of a lateral wall of the projection.
