FIELD: construction.

SUBSTANCE: invention is related to half-precast building slabs. Half-precast wood-reinforced concrete slab includes load-bearing beams, prefabricated filling elements, and a concrete layer laid on them, reinforced with a mesh. The load-bearing beams consist of a lower wooden belt of glued lamellas and a reinforcing cage of V-shaped transverse rods arranged with variable pitch, united at the top by a single longitudinal rod forming the upper belt of the beam, and two lower rods connected to the lower wooden belt by means of brackets.
