Composite wall for building exterior wall and construction method thereof

Abstract

The invention relates to a composite wall body of a building external wall and a construction method of the composite wall body. The composite wall body comprises an external hanging plate used as theouter lateral face of the wall body and an inner lateral plate used as the inner lateral face of the wall body. The external hanging plate is fixed to a keel through hanging connecting components. The inner lateral plate is fixed to a stand column. A heat preservation layer is arranged between the external hanging plate and the inner lateral plate in a filling mode. The keel and the stand columnare arranged in the heat preservation layer. The distance between the external hanging plate and the keel can be adjusted. The composite wall body has the effect of facilitating construction.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a composite wall for building exterior walls and a construction method thereof. Background technique [0002] Building energy saving is a worldwide trend, and the energy saving of envelope structure is the top priority of building energy saving. The focus of the envelope structure is the exterior wall, whose heat transfer heat consumption accounts for 33% to 34% of the total heat consumption of the building, and the energy saving of the exterior wall occupies a non-negligible position in building energy conservation. Improve the performance of material insulation, durability, mechanics and fire prevention, and realize the simultaneous design and construction of wall insulation and building structure, so that the quality is safe and reliable, the insulation and fire performance are good, and the insulation and energy saving are the same as the life of the building.

AI Technical Summary

Problems solved by technology

[0003] At present, building energy conservation is limited to plastering thermal insulation mortar on the surface of the external wall and hanging thermal insulation boards. Although the external thermal insulation technology has more advantages than the internal thermal insulation and sandwich thermal insulation technologies, the quality of the external thermal insulation is uncontrollable on site, and it is easy to cause air-conditioning. Drums fall off and other quality problems, and even cause fire disasters; in terms of exterior wall decoration, most of the current dry-hanging stone technology is used, but it is prone to cracking, deformation, whitening, discoloration, falling off, and poor thermal insulation performance.
