PUNCHING SHEAR REINFORCEMENT FOR REINFORCING FLAT-PLATE SLAB

摘要

The present invention is installed in the slab and column joints in reinforced concrete foundation and flat plate structure to increase the resistance to punching shear failure of the slab, made of a simple structure, easy to install reinforced flat plate slab punching shear reinforcement will be. Flat slab punching shear reinforcing body according to the present invention is a plurality of truss reinforcing bars 20 and a plurality of straight connection reinforcing bar 30 is arranged in parallel, the truss reinforcement 20 is the upper horizontal portion 21 and The lower horizontal portion 23 is repeatedly bent so as to be connected by the vertical portion 22, and the connecting reinforcing bar 30 is joined by spot welding inside the lower end of the side vertical portion 22a of the truss rebar 20, The connecting rebar is joined to the center lower surface of the upper horizontal portion 21 of the truss rebar 20 by spot welding, and the connecting rebar is connected to the center upper surface of the lower horizontal portion 23 of the truss rebar 20 to the spot welding. It is characterized by being bonded by.
