METHOD TO REINFORCE WOODEN BEAMS OF FLOOR SLABS Russian patent published in 2013 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: reinforcement method includes removal of floor structures, clearing of a beam-to-beam filler, assembly of reinforcement elements and development of a stiff slab structure. The stiff slab structure is developed by conversion of a wooden beam slab into a system of composite ribbed spatially working slabs. Beams are prepared by levelling of their upper surfaces. Veneer-like reinforcement slabs are laid onto beams in longitudinal direction and fixed, being tightly pressed to beams with the help of links. Links provide for perception of moving forces arising under a new increased load. Reinforcement slabs are laid with account of the ratios between the width of the reinforcement slab and beam pitch and accordingly with usage or without usage of filling slabs. Filling slabs are used to fill clear spaces between reinforcement slabs, and they are rested onto crosspieces, which are additionally installed between beams.

EFFECT: provision of efficient reinforcement of a beam slab, reduced labour intensiveness, material intensity and preservation of slab height.
