Heat preservation and decoration integrated outer wall structure and construction method thereof

Abstract

The invention provides a heat preservation and decoration integrated outer wall structure and a construction method thereof. The outer wall structure comprises a structural wall body and a heat preservation and decoration integrated wallboard installed on the structural wall body, the heat preservation and decoration integrated wallboard is sequentially provided with a decoration surface layer, aconcrete layer and a heat preservation layer from outside to inside, the decoration surface layer and the heat preservation layer are fixedly combined into a whole through the concrete layer, a latticed steel member is pre-buried in the concrete layer, a plurality of through holes are formed in the latticed steel member to serve as mounting holes, the structural wall body is provided with a plurality of fixing holes, and the heat preservation and decoration integrated wallboard is fixedly connected to the structural wall body through installation components which penetrate through the mountingholes and stretch into the fixing holes. According to the outer wall structure, the heat preservation and decoration integrated wallboard is connected and fixed to the structural wall body through the installation components penetrating through the mounting holes of the latticed steel component and stretching into the fixing holes, so that the procedure of additionally manufacturing a hanging plate keel on the structural wall body can be omitted during installation, field welding work is reduced, materials and labor are saved, and meanwhile the strength of an outer wall structure is guaranteed.

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 energy consumption of building insulation, and at the same time makes the heat conduction of the wall insulation layer uneven, resulting in 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 installing the existing thermal insulation and decoration integrated wall panels, 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 High cost of materials, materials and labor
