Assembled integral type concrete civil air defense closed wall body

Abstract

The invention discloses an assembled integral type concrete civil air defense closed wall body. The wall body comprises prefabricated double-blank concrete walls, cast-in-place concrete solid cores and cast-in-place concrete members; each prefabricated double-blank concrete wall comprises an outer side prefabricated wall skin, an inner side prefabricated wall skin and reinforcing ribs; and the reinforcing ribs are uniformly arranged between the outer side prefabricated wall skins and the inner side prefabricated wall skins. Load-bearing steel bars are arranged in the inner side wall skins and the outer side wall skins of the prefabricated double-blank concrete walls, the load-bearing steel bars are thrown out of the outer side prefabricated wall skins and the inner side prefabricated wall skins by a certain extension length, and the prefabricated double-blank concrete walls are used for being connected with the cast-in-place concrete members; the reinforcing ribs can be concrete ribs, steel plate ribs, glass fiber reinforced plastic ribs or combined section connecting pieces and have the function of reinforcing the integrity of the wall body; and compared with a traditional wall body which is only provided with tie bars, the wall body has higher lateral integrity.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled integral concrete airtight wall for air defense. Background technique [0002] With the state's control of mining resources, environmental protection requirements, and rising labor costs, the state requires the construction industry to be more environmentally friendly and energy-saving, and has also introduced various energy-saving and environmentally-friendly building technologies, such as prefabricated airtight walls for air defense. The prefabricated components of the prefabricated building are standardized production in the factory to ensure quality. Among them, the prefabricated laminated wall panels reduce the construction process of erecting frames and formwork installation, which can reduce manpower requirements, reduce costs such as labor and formwork materials, and speed up construction. The speed reduces the construction waste on the const...

AI Technical Summary

Problems solved by technology

The prefabricated components of the prefabricated building are standardized production in the factory to ensure quality. Among them, the prefabricated laminated wall panels reduce the construction process of erecting frames and formwork installation, which can reduce manpower requirements, reduce costs such as labor and formwork materials, and speed up construction. speed, reduce the construction waste on the construction site, and save construction costs, but the existing airtight walls of civil air defense have problems such as insufficient integrity of the wall and insufficient stability of the structure.
