Building method for assembly type cast-in-place cavity building cover

Abstract

The invention provides a method for assembling a prefabricated cast-in-place cavity cover, the steps of which are as follows: making the prefabricated cavity plate on site, and transporting the prefabricated cavity plate to the construction site; For beam reinforcement, the width of the formwork is 200mm greater than the width of the beam; the lower surface of the formwork is supported vertically by the support rods; The exposed rib beam reinforcement at both ends of the cavity slab extends into the beam reinforcement, and the rib beam reinforcement extending into the beam reinforcement is bound or welded; and then the process of the upper flange plate of the cast-in-place reinforced concrete floor is completed. The structural steel bars are laid on the beam steel bars and the assembled cavity slab, and the concrete is poured to form an assembled cast-in-place cavity floor. The assembled cavity panel produced by the above process has strong integrity, reasonable structure, high quality standard, controlled process, and good self-insulation and sound insulation performance.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to an assembly method technology of an assembled cast-in-place 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...

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 a method for building an assembled cast-in-place cavity floor; , 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 the industrialized production of prefabricated floor slabs is organically combined with pouring reinforced concrete on site. Optimize the existing frame shear wall structure system technology, transform and upgrade the existing prefabricated frame shear wall structure system, and replace 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 formwork 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
