Heat-preservation precast wall body and assembled house

Abstract

The invention relates to a heat-preservation precast wall body and an assembled house, and belongs to the technical field of walls of fixed buildings. The heat-preservation precast wall body is a wall body which is built in advance by building blocks from bottom to top before conventional wall building construction, each building block is provided with cavities and small column holes, which penetrate through the corresponding building block body in the height direction, and the cavities and the small column holes in each layer of building blocks separately penetrate through the cavities and the small column holes in the adjacent layer of building blocks which are built up and down; a stand column steel pipe or a stand column reinforcing bar is mounted in each cavity, or a heat-preservation sheet is clamped in each cavity, concrete is stuffed in each cavity in which the stand column steel pipe or the stand column reinforcing bar is mounted so that a core column is formed; multi-layer building blocks which are built up and down are mutually fixed into a whole in a manner that high strength concrete is poured in the small column holes which are partially penetrated; one or more reinforcing bars which are used for hoisting and assembling the wall body are arranged in the wall body, and are mounted, inserted and fixed in the high strength concrete in the small column holes. The heat-preservation precast wall body and the assembled house are safe and firm in structure, and besides, have the functions of heat preservation and noise elimination.

Description

technical field [0001] The invention relates to a thermal insulation prefabricated wall body and an assembled house, belonging to the technical field of walls for fixed buildings. Background technique [0002] The energy consumption of buildings in foreign developed countries accounts for 30% to 40% of the total energy consumption of the society, and the energy consumption per unit area of ​​buildings in my country is still 3 to 5 times that of developed countries with similar climates. Building energy conservation is the most potential and most direct and effective way among various ways of energy conservation. Among the building energy consumption, the energy consumption caused by the wall accounts for about 60% of the total building energy consumption, so wall insulation is the key to realizing building energy saving. [0003] According to the applicant's understanding, although the existing internal thermal insulation wall has good thermal insulation performance, its th...

AI Technical Summary

Problems solved by technology

[0003] According to the applicant's understanding, although the existing internal thermal insulation wall has good thermal insulation performance, its thermal insulation material is pasted on the inner side of the load-bearing wall, which makes it difficult to hang objects on the wall with internal thermal insulation, and even install curtain boxes to dissipate heat. devices are more difficult

[0004] The existing external thermal insulation wall has no effective protection on the outside of the thermal insulation material, the thermal insulation material is easy to fall off, unsafe, and the overall durability of the wall is poor; at the same time, due to the complicated construction process and relatively many manual control processes during the construction process, the construction quality is low , The construction speed is slow, which affects the energy saving efficiency of the building and the safety of the building
