[0002] In engineering construction, such as the construction process of exterior wall insulation and decorative surface, the effect of insulation layer and decorative surface is very important. Traditional rock wool is directly fixed on the exterior wall. There are some problems in the construction process: 1. The moisture content of insulation material is difficult to control. During construction, bad weather such as rain, snow and fog, construction process time, etc. will increase the moisture content of insulation material, the moisture of subsequent process will penetrate into insulation material or the moisture of subsequent process will enter insulation material after evaporation, etc., which will increase the moisture content in insulation layer; 2. There is an atmospheric pressure difference between insulation layer and outdoor air. The insulation layer is a closed system and is not connected to the outside. The moisture or air in the insulation layer will expand and contract during the winter rainy season, and there will be an atmospheric pressure difference. If no exhaust and ventilation measures are taken, the consequence is that the insulation layer of the exterior wall will fall off due to the expansion and contraction of moisture and air between the insulation layer and the decorative layer, and the decorative surface layer of the exterior wall will be easily cracked, damaged and fall off, thus affecting the service life and appearance of the insulation layer and decorative layer.

[0005] A further improvement of the technical solution of the utility model is that the length of one end of the exhaust pipe extending out of the decorative surface layer and then folding down is 3 cm.

[0006] A further improvement of the technical solution of the utility model is that the interval between adjacent exhaust pipes is 6m.

[0007] A further improvement of the technical solution of the utility model is that the interval between adjacent exhaust holes is 15 cm.

The insulation layer of the utility model is installed on the main structure before construction, which has beautiful appearance, convenient installation, low cost, obvious exhaust effect, and extends the service life of the insulation layer and decorative layer. Compared with the traditional rock wool that is directly fixed on the exterior wall without taking any exhaust measures, the utility model can avoid the insulation layer and decorative layer from being damaged due to moisture and air thermal expansion and contraction, and is also suitable for the protection of the insulation layer inside the dry-hanging stone on the exterior wall.

[0013] 2. The exhaust device of the utility model has two forms. The point-type exhaust pipe is fixed on the structural layer by a fixing piece, and the strip-type exhaust pipe is directly fixed on the structural layer by a fixing card. Different styles are selected according to different environmental humidity requirements. When the floor is low and the outer wall area is small, the point-type exhaust pipe is suitable; when the floor is high and the outer wall area is large, the strip-type exhaust pipe is suitable.

The insulation layer and the outdoor air are adjusted for air pressure through the exhaust pipe, which can improve the overall construction quality, extend the service life of the insulation layer and the decorative surface layer, and save maintenance costs.

[0019] The present invention is further described in detail below in conjunction with the embodiments:

[0020] An exhaust and pressure stabilizing device for an exterior wall insulation layer comprises an exhaust pipe 3 arranged in an insulation layer 1 and a decorative surface layer 2. The exhaust pipe 3 preferably has a diameter of 1 cm and is made of PVC or stainless steel pipe. One end of the exhaust pipe 3 extends out of the decorative surface layer 2 and then turns down. The length of the turning down is 3 cm. The other end of the exhaust pipe 3 is fixedly connected to a structural layer 4. A plurality of exhaust holes 5 are evenly arranged on the exhaust pipe 3. The exhaust pipe 3 is punched at intervals of 15 cm as the exhaust holes 5. The exhaust holes 5 preferably have a diameter of 5 mm. Water vapor enters the exhaust pipe 3 through the exhaust holes 5 and overflows or dries in the exhaust pipe 3. The contact part between the exhaust pipe 3 and the decorative surface layer 2 is sealed with weather-resistant glue to prevent rainwater and water vapor from entering the exhaust pipe 3 and damaging the insulation layer or the bonding between the insulation layer and the decorative surface layer and the structural layer. The exhaust pipe 3 comprises a point-type exhaust pipe and a strip-type exhaust pipe. Different styles are selected according to different environmental humidity requirements.

[0021] like Figure 1 to Figure 2 As shown, when the floor is lower and the outer wall area is smaller, the point-type exhaust pipe is suitable. The cross section of the point-type exhaust pipe in the insulation layer 1 and the decorative surface layer 2 is a crank-type structure. The horizontal length of the point-type exhaust pipe can be adjusted according to the thickness of the insulation layer and the decorative surface layer. The point-type exhaust pipe is fixedly connected to the fixing member 6 by a non-slip self-tapping screw. The fixing member 6 is preferably 5mm thick and 50*50mm in size. The fixing member 6 can be evenly arranged every 6m according to the size of the building on site. The exhaust pipe 3 and the fixing member 6 can be sealed by a thin rubber sealing sheet to prevent a gap between the fixing member 6 and the exhaust pipe 3, and water vapor leaking into the insulation layer 1. The fixing member 6 is anchored on the structural layer 4 by four expansion bolts 7. The fixing member 6 can be processed in advance by the factory and sprayed with anti-rust paint for protection.

[0022] like Figure 3 to Figure 4As shown, when the floor is high and the exterior wall area is large, a strip exhaust pipe is suitable. The cross section of the strip exhaust pipe in the insulation layer 1 and the decorative surface layer 2 is a combination of a vertical through-length pipe and a crank-type structure. The vertical through-length pipe of the strip exhaust pipe is fixed on the structural layer 4 by a plurality of fixing clips 8, and the adjacent fixing clips 8 are spaced 1 meter apart. The strip exhaust pipe is evenly arranged on the structural layer 4 at intervals of 6 meters.

[0023] The point-type exhaust pipe of the utility model is fixed on the structural layer by a fixing piece, and the strip-type exhaust pipe is directly fixed on the structural layer by a fixing card. Different styles are selected according to different environmental humidity requirements: the point-type is suitable for lower floors with smaller external wall areas; the strip-type is suitable for higher floors with larger external wall areas. The exhaust pipe is tightly wrapped by the insulation layer, water vapor overflows through the exhaust pipe or is air-dried through the exhaust pipe, and the insulation layer and outdoor air are adjusted for air pressure difference through the exhaust pipe, which can improve the overall construction quality, extend the service life of the insulation layer and the decorative surface layer, and save maintenance costs.
