Cold-formed thin-walled steel tic-tac-toe floor slab structure and construction method thereof

Abstract

The invention discloses a cold-formed thin-walled steel tic-tac-toe floor slab structure and a construction method thereof. The floor slab structure comprises a group of slab modules successively spliced and lightweight concrete layers; each slab module comprises a light steel frame, a group of heat insulation plates and a profiled steel plate; each light steel frame is of a rectangular frame structure formed by connecting a group of longitudinal steel rod pieces and at least two groups of transverse steel rod pieces; each group of heat insulation plates are correspondingly filled in latticesof the light steel frame; each profiled steel plate is laid on the top of the corresponding light steel frame; a baffle is arranged on top side of each slab module along the pass length of the longitudinal edge of the corresponding light steel frame; a first connecting plate is arranged at the bottom of each slab module; the bottoms of each two adjacent slab modules are connected by the first connecting plate; the lightweight concrete layers are poured between the tops of the profiled steel plates and the adjacent baffles. The floor slab structure solves the technical problems of poor sound insulation, fireproof, waterproof and bearing performance of a traditional floor slab, and the technical problems of low stability and high maintenance frequency after construction of each room.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a cold-formed thin-walled steel well-shaped floor slab structure and a construction method. Background technique [0002] The floor slab is an important structural component of the new light steel keel structure residential system. It not only has to bear the static and dynamic loads acting on it, but also has sufficient strength, rigidity and stability; for residential buildings, it must also achieve good Thermal insulation, sound insulation, and fire prevention performance, and after the floor slab of the next floor is installed, it will become a construction platform for the structure of the upper floor. At present, the floor slabs in light steel houses can be divided into two types according to their construction methods: cast-in-place light steel floor slabs (that is, wet methods) and fabricated light steel floor slabs (that is, dry methods). Among them, the currentl...
