FIELD: building, particularly to erect wall frames and inner walls, door assemblies, suspended ceilings, grids, fences and so on.
SUBSTANCE: building block is formed of wood and is shaped as rectangular parallelepiped with tie members made as projections and grooves. Projections and grooves are created in edges to be connected. Side edges of the block are provided with alternating ridges and valleys. Ridge height hr is 0.5-1.5 mm. Block width bb is greater than groove width bg by 0.3-1.7 mm. Ridges and valleys may be parallel to longitudinal block axis, transversal to longitudinal block axis or extend at an angle thereto. Ridge may have triangular or trapezoid cross-section.
EFFECT: possibility to compensate inaccuracies of modular wooden building block fabrication.
