building insulation wall

Abstract

The invention discloses a building thermal insulation wall, which comprises a building concrete base body, an insulation layer is installed on the outer surface of the building concrete base body, and a decorative layer is bonded and fixed to the outer surface of the insulation layer through a thin concrete layer, and the insulation layer includes a Insulation outer casing, a sealed installation cavity is opened inside the insulation outer casing, and a layer of insulation sponge layer is filled in the installation cavity close to the building concrete base. After the insulation sponge layer is installed in the installation cavity, a gas storage cavity is formed. The gas storage cavity It is arranged on the side close to the decorative layer, and an air-filling port is arranged on the top of the thermal insulation shell. The building insulation wall of the present invention has a very good sealing ability, and when a breakage occurs on the outer surface of the wall, the sealing device can be used to seal it in time to prevent the entry of external water vapor and dust, and alleviate the corrosion of the insulation layer. And the present invention has very good fire prevention capability and can effectively isolate the fire source.

Description

technical field [0001] The invention relates to the construction field, in particular to a building thermal insulation wall. Background technique [0002] During the construction of the building, in order to improve the insulation and noise performance, a foam insulation layer is usually added to the exterior concrete wall of the building. Because the insulation layer is relatively brittle and light, it is not easy to install heavy tiles on its outer surface, so it is generally just A decorative layer is provided, which can not only solve the aesthetic problem, but also cover the insulation layer. But its disadvantage is that since it cannot be installed with heavy things, the decorative layer is relatively light and thin, and it is easily damaged. Once there is a large impact, the decorative layer cannot bear the weight and will be damaged, and then the foam insulation layer is exposed. If it is not repaired in time, the external air, water vapor and dust will continue to ...

Problems solved by technology

But its disadvantage is that since it cannot be installed with heavy things, the decorative layer is relatively light and thin, and it is easily damaged. Once there is a large impact, the decorative layer cannot bear the weight and will be damaged, and then the foam insulation layer is exposed. If it is not repaired in time, the external air, water vapor and dust will continue to enter between the decoration layer and the insulation layer. In the long run, it will easily lead to corrosion and damage of the foam insulation layer, and the connection strength between the decoration layer and the insulation layer will become low and easy to fall off. Reduce the service life and affect the insulation effect of the insulation layer

[0003] In addition, due to the use of the foam insulation layer, its fireproof performance must be improved. Once a fire occurs, the foam insulation layer must be isolated, otherwise the external flame will quickly spread the fire when it contacts the insulation layer, increasing the danger. There are still many deficiencies in fire prevention measures
