Combination method of steel-structured and assembled-type hollow floor system

Abstract

The invention provides a combination method of a steel-structured and assembled-type hollow floor system. The method comprises the following steps that steel columns or static concrete steel columns are assembled on site; I-shaped steel beams formed by upper flange plates, lower flange plates and web plates are assembled; the bottom faces of the lower flange plates of the I-shaped steel beams or the middles of assembled hollow plates are vertically supported by support rods, and the support rods bear the pressure of construction loads; the assembled hollow plates are hoisted on the inner sides of the lower flange plates of the I-shaped steel beams, rib beam steel bars exposed out of the two ends of the assembled hollow plates stretch into the I-shaped steel beams, and the portions, stretching into the I-shaped steel beams, of the rib beam steel bars are welded or bound; the upper flange plate process of the cast-in-situ steel bar concrete floor system is completed, constructional steel bars are laid on the surfaces of the upper flange plates of the I-shaped steel beams and the upper surfaces of the assembled hollow plates, concrete is poured, and then the steel-structured and assembled-type hollow floor system is formed. The assembled hollow plates produced through the process are high in integrality, reasonable in structure, high in quality standard, controllable in process and good in self-insulation performance and sound insulation performance.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to a combination method technology of a steel structure assembled 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 realizatio...

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 combination method of steel structure assembled 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
