Description

An external wall insulation system

technical field

The utility model relates to the technical field of building materials, in particular to an external wall thermal insulation system.

Background technique

In recent years, due to the continuous improvement of the requirements for energy conservation and environmental protection, building energy conservation has become an important link in improving the energy efficiency of the whole society. Building materials and building insulation materials are the most basic conditions for realizing building energy conservation. At present, building envelope structure The thermal insulation measures are increasingly strengthened, and the development of external wall thermal insulation is the most rapid, and its thermal insulation effect is getting better and better.

The existing thermal insulation wall structure is generally composed of a base wall, a thermal insulation layer composed of thermal insulation materials, and an external coating, but the above-mentioned structures have low firm strength, poor stability, and short service life, which cannot meet people's needs; , With the change of the external environment temperature, especially in winter when the indoor and outdoor temperature difference is large, the existing thermal insulation wall structure is very easy to produce a cold bridge effect, which makes the external water vapor penetrate into the base wall, resulting in the phenomenon of house dampness and mildew.

SUMMARY OF THE INVENTION

The purpose of the utility model is to overcome the deficiencies of the above-mentioned technologies, and to provide an external wall thermal insulation system with simple structure, scientific design and high firmness, which can effectively solve the problem of damp and moldy houses caused by the cold bridge effect.

In order to achieve the purpose of the above utility model, the technical scheme adopted by the utility model is: an external wall thermal insulation system, including a foundation wall body, the outer side of the foundation wall body is sequentially provided with a thermal insulation layer and a surface coating layer, the thermal insulation layer and The foundation wall is adhered by the No. 1 mortar layer, and the thermal insulation layer and the surface coating layer are adhered by the No. 2 mortar layer. It is composed of two layers of extruded polystyrene boards that are attached to each other. The edges of the two layers of extruded polystyrene boards are bonded by adhesives. Several through holes are opened on each layer of extruded polystyrene boards. The through holes on the polystyrene board are arranged in a staggered manner, and several water storage tanks are respectively opened on the surfaces where the two layers of extruded polystyrene boards are attached to each other, and the water storage tanks and the through holes are staggered from each other; the No. 2 mortar layer is plastering For the mortar layer, a layer of mesh cloth is immersed in the No. 2 mortar layer.

Further, a putty layer is also provided between the No. 2 mortar layer and the surface coating layer to remove uneven defects on the surface of the No. 2 mortar layer.

Further, a layer of mesh cloth is also arranged between the two layers of extruded polystyrene boards, and there is a space between the edge of the mesh cloth and the edge of the extruded polystyrene board, and the mesh cloth is used to prevent the mortar from entering the extrusion molding. The through holes of the polystyrene board penetrate into the gap between the two layers of extruded polystyrene boards, and the mesh cloth provides a space for the infiltration of external water vapor to condense into water.

Further, the mesh cloth is a glass fiber mesh cloth.

The beneficial effects of the utility model are as follows: through the through holes on the thermal insulation layer, the adhesion between the mortar and the thermal insulation layer is made tighter; the water vapor formed by the large temperature difference can be stored in the water storage tank of the extruded polystyrene board, preventing the The foundation wall penetrates and solves the problem of house dampness and mildew caused by the cold bridge effect; the thermal insulation wall has simple structure, scientific design, high firm strength, good stability and long service life.
