Fabricated formwork-removal-free prefabricated floor bottom plate structure

Abstract

The invention discloses an assembly type formwork-removal-free prefabricated floor bottom plate structure. The structure is formed by combining a formwork-removal-free prefabricated bottom plate, longitudinal steel bars, C-shaped light steel, longitudinal stiffening ribs, transverse stiffening ribs and galvanized iron sheet hanging rings. The structural system is light in weight and very convenient to transport, hoist and assemble; according to the structure, the content of concrete is not increased, the content of steel bars is not increased, the cost is saved for a construction party, the aim of fast period is achieved, the workload of deepening design is saved for a design party, the construction progress is accelerated for the construction party, the construction quality is better controlled, and the productivity is completely released for a component producer; therefore, all parties participating in the project obtain respective benefits.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to an assembled formwork-free prefabricated floor plate structure. Background technique [0002] The horizontal prefabricated components in the existing prefabricated buildings are mainly truss reinforced concrete composite panels (60mm thick bottom plate). This truss reinforced concrete composite panel is equipped with triangular reinforced concrete trusses, and the wave-shaped web bars in the triangular reinforced concrete truss are not stressed for structural settings. Therefore, the steel content of the floor slab is increased; the thickness of the prefabricated bottom plate of the truss reinforced concrete composite slab is 60mm, and the thickness of the cast-in-place layer is 70mm, and the total thickness is at least 130mm. Compared with the traditional cast-in-place slab, the slab thickness also increases, which increases The content of concrete is increased; ...

Problems solved by technology

[0002] The horizontal prefabricated components in the existing prefabricated buildings are mainly truss reinforced concrete laminated slabs (60mm thick bottom plate). This truss reinforced concrete laminated slab is equipped with triangular steel trusses. Therefore, the steel content of the floor slab is increased; the thickness of the prefabricated bottom slab of the truss reinforced concrete composite slab is 60mm, and the thickness of the cast-in-place layer is 70mm, and the total thickness is at least 130mm. The concrete content is reduced; the amount of steel bars and concrete materials increases, which directly leads to an increase in cost, and the truss reinforced concrete laminated slab is not convenient for transportation, hoisting, and assembly due to its high, wide, and heavy characteristics, and there are many problems during installation on the construction site, so In the process of popularizing prefabricated buildings, construction parties are not very enthusiastic about the application of this kind of prefabricated floor slabs
