Partially prefabricated sandwich wall plate and its wall structure and building

Abstract

The invention provides a partially prefabricated sandwich wall plate and its wall structure and building. The partially prefabricated sandwich wall plate comprises a prefabricated thermal insulation plate comprising a thermal insulation core layer, a steel wire mesh, diagonal plug wires, a prefabricated surface layer and a rear rendering coating on the external surface of the prefabricated surfacelayer of the prefabricated thermal insulation plate. The roof structure of the building is composed of a partially prefabricated sandwich roof plate or a roof plate in other form. The partially prefabricated sandwich wall plate combines prefabrication in a factory and on-site construction. The prefabricated thermal insulation plate used by the partially prefabricated sandwich wall plate and roofplate can be industrialized and produced in standards. The production device is simple. The product quality is stable. On the construction site, transportation and installation are convenient, construction processes are simple and construction conditions are low. The building structure is simple and reasonable, keeps warm, has good waterproof performances and good economy and is particularly suitable for the construction of a new rural area in the underdeveloped areas in the north.

Description

technical field [0001] The invention belongs to the technical field of building structures and construction thereof, and relates to thermal insulation and energy-saving buildings, in particular to partial prefabricated sandwich wall panels and their wall structures and buildings. Background technique [0002] Traditional low-rise buildings, especially rural residences, mostly adopt masonry structure, that is, the walls are generally made of brick masonry walls, and the floors and roofs are made of cast-in-place reinforced concrete slabs. This construction method has many wet operations on site, slow construction speed, and is easy to cause waste of materials and environmental pollution. At present, my country is vigorously developing prefabricated buildings, and applying prefabricated construction technology to low-rise buildings can solve a series of problems existing in traditional construction technologies. However, the existing prefabricated construction technology is m...

AI Technical Summary

Problems solved by technology

However, the existing prefabricated construction technology is mostly used in high-rise buildings, and there are problems such as cumbersome construction and high cost when used in low-rise buildings

[0003] On the other hand, traditional low-rise buildings, especially rural residences, do not pay enough attention to energy-saving design. The thermal insulation and energy-saving effect achieved through the wall and roof itself or external insulation is relatively poor. At the same time, the traditional external insulation method is prone to cracking, Hollowing, leakage, falling off, fire and other problems
