A thermal insulation and decoration integrated exterior wall structure and its construction method

Abstract

The invention provides a thermal insulation and decoration integrated exterior wall structure and a construction method thereof. The external wall structure includes a structural wall and an thermal insulation and decoration integrated wall panel installed on the structural wall. The thermal insulation and decoration integrated wall panel The decorative surface layer, the concrete layer and the thermal insulation layer are set in order in the inner part. The decorative surface layer and the thermal insulation layer are consolidated into one body through the concrete layer. The grid-shaped steel components are pre-embedded in the concrete layer, and there are multiple grid-shaped steel components. A through hole is used as a mounting hole; the structural wall is provided with a plurality of fixing holes, and the thermal insulation and decoration integrated wallboard is connected and fixed to the structural wall through the mounting member passing through the mounting hole and extending into the fixing hole. The present invention connects and fixes the thermal insulation and decoration integrated wallboard to the structural wall through the installation member that passes through the installation hole of the grid-shaped steel member and extends into the fixing hole, so that it is unnecessary to make additional hanging boards on the structural wall during installation The keel process reduces field welding work, saves materials and labor, and at the same time ensures the strength of the outer wall structure.

Description

technical field [0001] The invention belongs to the technical field of heat preservation and decoration of building exterior walls, and in particular relates to a heat preservation and decoration integrated exterior wall structure and a construction method thereof. Background technique [0002] In recent years, prefabricated buildings have been vigorously developed in my country, and the integrated wall panels with thermal insulation and decoration are emerging in an endless stream. This type of wall panels is composed of thermal insulation layer and decorative layer. The decorative layer protects the thermal insulation layer and is also beautiful. At present The decorative layers of thermal insulation and decoration integrated wall panels on the market mainly fall into the following two categories: [0003] 1) Inorganic layer decorative layer, including cement base material, gypsum, etc. However, if this kind of inorganic decorative layer is thick, the integrated wallboard ...

AI Technical Summary

Problems solved by technology

However, if this kind of inorganic decorative layer is thick, the integrated wallboard cannot bear the self-weight of the decorative layer only through the bonding of its thermal insulation layer and the structural wall. Destroy the exterior decoration surface, and cause cold and heat bridges at the same time. The existence of cold and heat bridges increases the heat preservation energy consumption of the building, and at the same time makes the heat conduction of the wall insulation layer uneven, causing condensation, mold and even dripping on the inner walls of the house.

If the inorganic decorative layer is thin, the self-protection ability will also be reduced when the self-weight is reduced, and it is not suitable for multi-storey, high-rise buildings that will encounter strong wind loads.

[0004] 2) Organic decorative layers or metal decorative layers, including PVC, wood-plastic, color steel decorative panels, etc., such decorative layers are stronger than inorganic decorative layers of the same thickness, so organic decorative layers or metal decorative layers of the same strength are thinner , lightweight, but this kind of material is far lower than the inorganic decorative layer in terms of weather resistance against ultraviolet rays, cold and heat, wind and rain, bacteria, rust, acid rain corrosion, etc., and is not suitable for buildings with high durability requirements.

[0005] When the existing thermal insulation and decoration integrated wall panels are installed, it is usually necessary to make another scraper keel on the structural wall, and the thermal insulation and decoration integrated wall panel is fixed on the structural wall through the scraper keel. This process requires on-site welding, which is time-consuming Material, material and labor costs are high
