Assembling type overlapped cavity floor cover

Abstract

The invention provides an assembling type overlapped cavity floor cover. The assembling type overlapped cavity floor cover comprises columns, a main beam, an auxiliary beam, upper-flange-free cavity plate components and cast-in-situ reinforced concrete floor cover upper flange plates. The assembling type overlapped cavity floor cover is characterized in that the auxiliary beam is arranged in a column net formed by the columns and the main beam; the upper-flange-free cavity plate components are arranged on a framework of the auxiliary beam; the assembling type upper-flange-free cavity plate components and the beams are arranged in a vertical or horizontal overlapping manner, the vertical overlapping manner is to overlap the assembling type upper-flange-free cavity plate components to the top surfaces of the beams, and the horizontal overlapping manner is to overlap the assembling type upper-flange-free cavity plate components to the horizontal surfaces of the beams; and reinforced concrete is poured on the upper surfaces of the upper-flange-free cavity plate components to form assembling type cavity floor cover upper flange plates through overlapping, so as to form the assembling type overlapped cavity floor cover.

Description

Technical field [0001] The invention relates to a fabricated building system technology, in particular to a fabricated laminated cavity floor technology. Background technique [0002] In the 1980s, the production of precast concrete components in China was in a major development stage. In the process of housing construction in the country, the floor adopts hollow precast slab structure, large slab structure, cast-in-place concrete structure, cast-in-place concrete hollow floor structure, and cast-in-place concrete frame structure. , Cast-in-place concrete frame shear wall structure, etc., with the housing industrialization process, a few days ago, the steel-concrete composite structure and the steel-concrete composite cavity floor structure system have been rapidly developed. China's prefabricated floor has just started, adopting Longitudinal laminated board, that is, the assembled solid large board is laminated on the beam. [0003] For example, ZL200410082381.9 "a kind of fastin...

Problems solved by technology

[0007] The purpose of the present invention is to promote the progress of building science and technology, organically combine the industrially produced prefabricated assembly-type cavity plate components without upper flanges with the reinforced concrete beams and columns poured on site to form an assembly-type laminated cavity floor, which adopts horizontal Superposition can also save the benefits generated by the floor space occupied by the exposed beams, and optimize the existing frame structure technical system; make full use of the advantages of industrialization of the factory, prefabricate and produce assembly-type upper-flange cavity plate components, and solve the weight of the components , Poor structural integrity, difficult implementation controllability, environmental pollution caused by on-site construction, heavy quality, high construction cost, slow progress of the project, a large number of building formwork and steel supports, resulting in long mold making time and affecting the construction speed, etc.
