FIELD: low-height construction.
SUBSTANCE: invention relates to wood-concrete self-stressed roofing of a building. Wood-concrete cover includes reinforced non-metallic rods, glued two-wall wooden beams filled with expanding concrete, reinforced with non-metallic mesh concrete slab, connecting beam and anchors. In the lower zone of the glued two-girder beam rectangular cross-section is glued across and in the middle zone of its cross section—stepped lamellar nails, forming in middle section of cross-section through rectangular stepped holes with length increasing to supports, filled with monolithic concrete, creating "keys" of variable cross-section.
EFFECT: technical result consists in increasing the rigidity of the beam.
