Description

Armored foam concrete insulation walls

technical field

Background technique

Energy conservation, pollution reduction and realization of low-carbon economy are the basic national policies of our country, among which building energy conservation is a very important aspect. Building energy saving is also the key to exterior wall and roof insulation. However, the exterior wall insulation technologies that are being used or promoted in China include: ①External application of foam plastic boards; ②Use foam plastic boards as exterior wall sandwiches; The slurry made of microbeads and cement is externally applied to the external wall; ④ The external wall is integrally poured with foamed concrete with a bulk density of (700-1200) kg/m ³ . Among them, the first three types of walls all have disadvantages in different degrees, such as large overall volume of the wall, low compressive strength of the outer wall surface, and low service life, which cannot be consistent with the service life of the building body. When a fire breaks out, a large amount of toxic substances and black smoke will be produced, making it easy for people to inhale the smoke and difficult to escape, damaging the environment and possibly permanently endangering human health and polluting the environment. Foam concrete is integrally poured into the external wall. Although the total bulk density of the wall is reduced and there is no secondary pollution, there are problems such as easy cracking and water absorption, which reduces the thermal insulation performance and the whitewashing mortar is easy to fall off. Chinese patent application No. 201010543013.5 discloses an ultra-light, super-strong and low-heat-transfer concrete composite bionic wall technology, which has high production costs, difficult construction, and small stress points on concrete slabs.
