Can be assembled with environmentally friendly exterior walls

Abstract

The invention belongs to the technical field of combined walls and particularly relates to a combined wall which has the heat insulation function, the sound insulation function and the fireproof function. The combined wall is convenient to install and low in weight. According to the technical scheme, the fabricated environment-friendly external wall is provided with an external wall body, two hanging pieces, a heat insulating wall, a first keel, a filler wall, a second keel and an internal wall body, wherein each hanging piece comprises a cross rod and two installation plates which are vertically arranged on the same side of the cross rod, a cross groove is formed in each cross rod, the sizes of the two installation plates are the same, four installation holes are formed in each installation plate, the upper end and the lower end of the external wall body are inserted in the cross grooves of the two hanging pieces respectively, and the hanging pieces are connected to the heat insulating wall after multiple screws penetrate through the installation holes. According to the fabricated environment-friendly external wall, the requirements for heat insulation, fire protection, sound insulation and warming of an external wall are met in a one-off mode, industrialized manufacturing is achieved, construction is achieved on a site through one-time hoisting, working efficiency is greatly improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of composite walls, in particular to a composite wall integrating heat insulation, sound insulation and fire prevention. Background technique [0002] At present, the methods of exterior walls are divided into five parts: exterior wall main body, exterior wall insulation, exterior wall waterproofing, exterior wall decoration and interior wall decoration. There are many methods and each part has very complicated procedures, resulting in waste of resources. For example, the current common practice of aerated concrete exterior walls for frame-shear buildings is to build walls with aerated concrete blocks at the reserved wall position after the main structure of the building is completed, and the insulation layer is made of extruded board or other insulation The material is pasted on the outer wall of aerated concrete with glue, and then the outer wall is covered with alkali-resistant glass fiber mesh, and the f...

AI Technical Summary

Problems solved by technology

There are many and complicated procedures, and glue and other industrial materials that are harmful to the human body are used. This method is relatively mature and convenient in the current construction industry.

However, it still cannot solve the problems of thermal insulation, fire prevention, sound insulation and warmth of the outer wall at once.

The method of exterior wall is complicated and needs to go through three to five processes to complete

The construction period is long, consumes a lot of labor and resources, and cannot meet the requirements of industrialization, industrialization, assembly, green and energy saving
