Assembly type prefabricated part for cavity floor system

Abstract

The invention provides an assembly type prefabricated part for a cavity floor system. The assembly type prefabricated part comprises reinforced concrete ribbed beams, an upper reinforced concrete flange plate, a lower reinforced concrete flange plate and a filling body. The reinforced concrete ribbed beams include at least two longitudinal reinforced concrete ribbed beams and a plurality of transverse reinforced concrete ribbed beams. The two rebar ends of each longitudinal reinforced concrete ribbed beam are exposed. A plurality of U-shaped rebars are arranged on reinforced concrete ribs. The filling body is a polyphenyl block or a plastic cavity or a cement cavity or a plate. The assembly type hollow floor produced through the procedures is strong in integrity, reasonable in structure, high in quality standard and good in self-heat preservation performance and sound insulation performance, and the working procedures are controllable.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to an assembled prefabricated component 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 of the ...

Problems solved by technology

[0007] The purpose of the present invention is to promote the process of housing industrialization, to improve the existing frame shear wall structure system by using an assembled prefabricated component for cavity floors; , to solve 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 cast-in-place reinforced concrete. Achieve the optimization of 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 overall on-site pouring, strong implementation technology, and on-site construction problems in the existing system Environmental pollution, heavy weight, high construction cost, slow progress of the project, exempting a large number of building templates and steel supports, resulting in long formwork time and affecting the construction speed; using steel supports and its structural parts are vulnerable to safety hazards and difficult to form industrialized production And other issues
