Cement foam insulation cover board on the outer layer of the building wall

Abstract

The invention relates to a wallboard for the field of buildings, and in particular relates to a cement foamed heat preserving cover board for a building outer wall. The cement foamed heat preserving cover board is formed by integrally compounding a surface layer and a lining, wherein a rib net is arranged between the surface layer and the lining in a solidifying manner, and more than one connecting pile is arranged on the surface of the lining. The cement foamed heat preserving cover board for the building outer wall, disclosed by the invention, is suitable for cement foamed heat preservation of various building walls, can be used for casting of a heat preserving layer of a new building, is also suitable for heat preserving reinforcement of an old building, and can enable the connection between the wall and foamed cement as well as between the foamed cement and the cover board to be stable; the wall and the cover board can be fixed with each other conveniently, the length of the connecting piles can be randomly adjusted, and the thickness of a foamed cement layer can be increased or reduced; the heat preserving layer of the building outer wall is good in strength, good in flame-retardant effect and long in service life; the cement foamed heat preserving cover board also has a function of reinforcing the wall.

Description

technical field [0001] The invention relates to a wallboard used in the construction field, in particular to a cement foam insulation cover board for the outer layer of a building wall. Background technique [0002] In the northeast region where the temperature is relatively cold, the building walls are thicker than those in the south, and the outside of the wall is provided with an insulation layer to resist the low temperature outside and maintain the temperature brought by the heating inside. The traditional insulation wall layer is mostly ready-made benzene board insulation blocks, which are pasted on the outside of the building wall. However, due to the cold climate in Northeast China, complex and changeable weather conditions, and large temperature differences between day and night, the insulation blocks pasted on the exterior walls of buildings are often The phenomenon of shedding occurs, so it brings certain hidden dangers to later management and maintenance and incr...

The traditional insulation wall layer is mostly ready-made benzene board insulation blocks, which are pasted on the outside of the building wall. However, due to the cold climate in Northeast China, complex and changeable weather conditions, and large temperature differences between day and night, the insulation blocks pasted on the exterior walls of buildings are often The phenomenon of shedding occurs, so it brings certain hidden dangers to later management and maintenance and increases construction costs, especially for modern high-rise buildings, it will bring certain dangers

Foamed cement has a good thermal insulation effect and a good reinforcement effect on the original wall. In recent years, it has gradually been favored by the construction industry. However, foamed cement is poured on site. Because it has no fixed shape, it cannot be directly applied to the wall. Outside the body, it is difficult to pour it on the vertical wall surface
