Outer wall for prefabricated wallboard and steel structure assembling

Abstract

The invention provides an outer wall for prefabricated wallboard and steel structure assembling. The outer wall is composed of section steel columns, section steel beams, door and window openings and prefabricated wallboards. The section steel columns are static concrete type section steel columns. The section steel beams are in an H shape. The prefabricated wallboard comprises reinforced concrete ribs, an inner wallboard or an outer wallboard and ribbed steel mesh hollow parts. The reinforced concrete ribs include the prefabricated wallboard side ribs and the prefabricated wallboard middle ribs. The reinforced concrete ribs are cavity ribs. The cavity ribs are formed by ribbed steel mesh cylinder. Exposed reinforcing bars are arranged on at least one side face in the side ribs of the prefabricated wallboard. The exposed reinforcing bars are connected with the section steel columns. According to the prefabricated wallboard components, the problems that an existing structural system is poor in overall on-site casting controllability and high in implementation technology, environmental pollution is caused by on-site operation, quality is poor, energy-saving and heat insulation functions are lost, and an insulating layer needs to be added are solved.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to an exterior wall technology in which a prefabricated assembled wall panel and a steel structure are combined. 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 block structures, fabricated wall panel structures, large slab structures, cast-in-place concrete structures, cast-in-place concrete hollow floor structures, and existing Poured shear wall structure, etc. With the industrialization of housing, steel-concrete composite structure and prefabricated precast concrete structure system have developed rapidly; , Combining traditional building material prefabricated components with cast-in-place reinforced concrete technology, and published a paper entitled "Precast Concrete Hollow Form and Housing Industrializatio...

Problems solved by technology

[0007] The purpose of the present invention is to promote the process of housing industrialization, using a combination of prefabricated wall panels and steel structures to improve the existing shear wall structure system; making full use of the advantages of factory industrialization to prefabricate and produce assembled wall panels Components, to solve the problems of the existing structural system, such as poor controllability of overall on-site pouring, strong technical implementation, environmental pollution caused by on-site construction, heavy weight, loss of energy-saving and thermal insulation functions, and the need to add thermal insulation layers; The solution is to organically combine industrialized production of prefabricated prefabricated wall components with on-site poured reinforced concrete to optimize the existing shear wall structural system technology, and to transform and upgrade the existing prefabricated shear wall structural system; especially The exposed steel bars of the prefabricated assembled wall panels are welded with the steel structure to reinforce the contact points; the inner wall panels and outer wall panels are built by combining ribbed steel mesh body and concrete, and the prefabricated assembled wall panel components are self-insulated with ribbed steel mesh As a result, the external wall is exempted from external insulation, and the reinforced concrete ribs are formed from ribbed steel mesh cylinders to form cavity ribs, and the ribbed steel mesh cylinders are poured with self-insulation materials formed by cement foaming slurry, which not only reduces the prefabricated assembly. The weight of the wall panel components can also cut off the cold bridge and realize the self-insulation function
