Prefabricated beamless floor composite slab based on stress and disassembly method thereof

Abstract

The invention provides a prefabricated beamless floor composite slab based on stress and a disassembly method thereof. The prefabricated beamless floor composite slab comprises a prefabricated composite floor, a prefabricated column connection node and a prefabricated composite slab connection node, and the prefabricated composite floor and prefabricated column connection node comprise entering the prefabricated composite floor into a prefabricated column protection layer to keep steel bar continuous with a prefabricated column; a prefabricated column stirrup is bound, and the prefabricated composite floor connection node comprises a cast-in-situ layer and a prefabricated composite floor layer. The connection node of the prefabricated composite slab of the invention can realize the support-free formwork of the floor, and promote construction efficiency, and the overlap requirements of the steel bar at the connection node can be ensured; the continuity kept with the steel bar of the composite floor can ensure the stress in a prefabricated column concentrated stress area well; in addition, the disassembly point of the prefabricated composite slab has a small bending moment or closes to 0, the reasonable stress design disassembly can reduce the design thickness of the floor and the usage of the steel bar, so the disassembly is more convenient.

Description

technical field [0001] The invention relates to the field of construction, in particular to a stress-based prefabricated beamless floor laminated slab and a splitting method thereof. Background technique [0002] The laminated slab is a better structural form that combines prefabricated and cast-in-place concrete. The laminated slab and the upper cast-in-place concrete layer are combined to form a whole and work together. Composite floor slabs have the advantages of integrity, high rigidity, good crack resistance, no increase in steel consumption, and formwork saving like cast-in-place slabs, and are representative of prefabricated building products. Prefabricated laminated floor slabs have the advantages of factory processing, fast construction speed, low comprehensive cost, good integrity, good seismic performance, and construction not affected by the climate. However, simple prefabricated laminated slabs are difficult to meet the requirements of normal engineering force ...
