Composite heat preservation outer wall system and construction method

Abstract

The invention relates to a composite heat preservation outer wall system, and belongs to the technical field of energy-saving buildings. The composite heat preservation outer wall system comprises a building wall body, wherein the building wall body is sequentially provided with a heat preservation structure, a connecting assembly and a curtain wall structure from inside to outside; the heat preservation structure comprises a plurality of rock wool boards arranged on the outer side of the building wall body, a plurality of convex parts are arranged on the sides, away from the building wall body, of the rock wool boards, the convex parts extend in the vertical direction, the convex parts are arranged in the horizontal direction, concave surfaces are formed between the adjacent convex parts, waterproof base plates are fixed to the sides, away from the building wall body, of the convex parts and the concave surfaces, and fixing pieces and adhesives are arranged between the rock wool boards and the building wall body; and the connecting assembly is arranged at the convex parts, and the curtain wall structure is installed on the sides, away from the building wall body, of the waterproof base plates through the connecting assembly. According to the scheme, the heat preservation performance of the building wall body can be effectively improved, the phenomenon that the rock wool boards fall off is effectively reduced, the service life of the heat preservation outer wall system is prolonged, and heat preservation and energy conservation of the building are achieved.

Description

technical field [0001] The application relates to the field of energy-saving buildings, in particular to a composite thermal insulation exterior wall system and a construction method. Background technique [0002] With the development of urban construction, the requirements for green buildings and building energy conservation are higher, and building energy consumption accounts for more than 30% of human energy consumption. It is urgent to develop new building materials for energy conservation, emission reduction and low-carbon economy. [0003] At present, the general way of building energy saving is to install insulation boards on the inner or outer walls to achieve energy saving and emission reduction of buildings. The rock wool board is an artificial inorganic fiber made of basalt as the main raw material and processed by high-temperature melting. It has the characteristics of light weight, small thermal conductivity, sound insulation and heat absorption, and Class A fir...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: as a fiber, the rock wool board has the characteristics of being afraid of water and moisture, and the generally installed waterproof layer cannot meet the moisture-proof requirements of the rock wool board, and it is easy to cause the rock wool board to be damaged by moisture , and the rock wool board is prone to delamination and shedding due to its low tensile strength
