Prefabricated assembly type cavity floor slab for cavity floor system

Abstract

The invention provides a prefabricated assembly type cavity floor slab for a cavity floor system. The prefabricated assembly type cavity floor slab comprises reinforced concrete rib beams, a reinforced concrete top flange plate, a reinforced concrete bottom flange plate and a filling body, wherein the reinforced concrete rib beams include at least two reinforced concrete longitudinal rib beams and multiple reinforced concrete transverse rib beams; the two ends of the rebar of the reinforced concrete longitudinal rib beam are exposed; multiple annular rebars are arranged on the surface of the reinforced concrete top flange plate; and the length is greater than 5800m, and the thickness is greater than 200mm. The assembly type cavity floor slab produced by the flow has the advantages of high integrity, reasonable structure, high quality standard, controlled processes and good self-insulation and sound insulation performance.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to a prefabricated and assembled cavity floor technology for a cavity floor. Background technique [0002] In the 1980s, the production of concrete prefabricated components in my country was in a stage of great development. In the process of housing construction, the country adopted hollow prefabricated slab structures, large slab structures, cast-in-place concrete structures, cast-in-place concrete hollow floor slab structures, and cast-in-place frame shear forces. Wall structure, etc. With the process of housing industrialization, steel-concrete composite structure and steel-concrete composite cavity floor structure system have been developed rapidly. [0003] For example, the ZL98231113.3 concrete thin-walled cylindrical member declared by the applicant is made into a sealed cylindrical filling body, which provides a tubular hollow filling body for the realization o...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to promote the industrialization process of housing, to improve the existing frame shear wall structure system by using a prefabricated assembled cavity floor slab for the cavity floor; The cavity floor slab solves the problems of construction, environmental protection, weight, cost, and work efficiency in the existing system; the overall force of the building structure is solved by pouring reinforced concrete on site, and organically combines industrially produced prefabricated floor slabs with on-site poured reinforced concrete To optimize the existing frame-shear wall structure system technology, transform and upgrade the existing prefabricated frame-shear wall structure system, and update it; solve the problems of poor controllability of the overall on-site pouring in the existing system, strong implementation technology, and on-site The construction causes environmental pollution, heavy weight, high construction cost, slow progress of the project, and the exemption of a large number of building formwork and steel supports, which leads to long time for formwork and affects the construction speed; the safety hazards caused by the fragile structural parts of steel supports and the difficulty of forming issues of industrial production
