Description

Technical Field

[0001] The utility model relates to the field of energy-saving building materials, in particular to a prefabricated thermal insulation and sound insulation wall. Background Art

[0002] With the continuous acceleration of the urbanization process, the urban population density increases, and noise sources such as transportation, industry, and construction also increase accordingly. Noise not only affects people's daily life and work efficiency, but may also cause damage to people's physical and mental health.

[0003] Under the background of global energy shortage and enhanced environmental awareness, building energy conservation has become an important development trend in the construction industry. However, traditional walls not only fail to reduce the heat loss caused by the indoor-outdoor temperature difference, but instead increase the working burden of equipment such as air conditioners and floor heating, greatly increasing the electric energy and costs.

[0004] In the current existing technologies, general sound insulation walls usually adopt relatively traditional single structures or simple multi-layer structures, and the installation process is more complex, and relatively more construction costs may be invested. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems and propose a prefabricated thermal insulation and sound insulation wall.

[0006] To achieve the above purpose, the following technical solutions are adopted:

[0007] The prefabricated thermal insulation and sound insulation wall includes a basic frame layer, an external protection layer, and also includes a sound insulation microporous partition layer and a vacuum insulation layer; the basic frame layer adopts a keel frame structure, and sound insulation cotton is filled in the gaps of the grid-shaped keel frame; the sound insulation microporous partition layer adopts a layered structure, including an inner layer gypsum board, a sound insulation felt, a microporous partition board, and an outer layer gypsum board. The inner layer gypsum board is connected to the basic frame layer, the sound insulation felt is connected to the inner layer gypsum board, and the microporous partition board is arranged between the outer layer gypsum board and the sound insulation felt; the vacuum insulation layer is a hollow rectangular plate, and the vacuum insulation layer includes an outer layer and an inner layer. The outer layer is a vacuum insulation board, and the inner layer can be filled with aerogel. A small hole is provided on the side of the vacuum insulation board, and vacuum pumping is performed through the small hole on the side of the vacuum insulation board. The vacuum insulation layer is connected to the outer layer gypsum board; the external protection layer adopts a multi-layer composite structure, and a waterproof and breathable film is arranged between the external protection layer and the vacuum insulation layer.

[0008] Preferably, the basic frame layer adopts a keel frame structure, the gaps between the grid-shaped keel structures of the basic frame layer are filled with sound insulation cotton, and the basic frame layer is connected and fixed to the wall through expansion bolts.

[0009] Preferably, the sound-insulating microporous partition layer adopts a layered composite structure, where the microporous partition contains tiny holes with a pore diameter of 0.1 - 10 microns, and each layer inside the sound-insulating microporous partition layer is fixed by screws or special fixtures.

[0010] Preferably, the vacuum insulation layer is divided into an outer layer and an inner layer. The outer layer is a vacuum insulation board, and the inner layer can be filled with aerogel. There is a small hole on the side of the vacuum insulation board, and the inner layer is evacuated through this small hole. The vacuum insulation layer is sealed and fixed using a sealing strip and a fixing fixture.

[0011] Preferably, the external protective layer adopts a composite structure. A waterproof and breathable membrane is provided between the external protective layer and the vacuum insulation layer. The waterproof and breathable membrane is attached to the outside of the vacuum insulation layer, and the external protective layer is fixed and connected to the wall through screws and fixing washers.

[0012] Preferably, each layer of the prefabricated thermal insulation and sound insulation wall is installed on the gap of the upper layer, and each layer is connected together with screws or expansion bolts.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: Installing sound insulation felts and microporous partitions further improves the sound insulation effect of the wall and greatly reduces the impact of noise on people. Aerogel is filled into the inner layer of the vacuum insulation layer and evacuated. Aerogel itself has excellent heat insulation properties, and the evacuation process can reduce the heat conduction between molecules and prevent a large amount of heat from passing through. This not only effectively reduces the temperature loss caused by the indoor-outdoor temperature difference but also alleviates the consumption of electric energy and costs to a certain extent. Moreover, when installing on the wall, each layer is fixed first and then installed on the wall separately. Therefore, during the manufacturing and implementation process, it is simpler, improving the convenience and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The prefabricated thermal insulation and sound insulation wall of the present utility model will be specifically described below with reference to the accompanying drawings.

[0020] As Figure 1 shown in the prefabricated thermal insulation and sound insulation layer, it includes a basic framework layer 10, an external protective layer 40, and also includes a sound insulation microporous partition layer 20 and a vacuum thermal insulation layer 30;

[0021] As Figure 2 shown, the basic framework layer 10 is made of lightweight and high-strength aluminum alloy, adopting a grid-shaped keel framework structure. Sound insulation cotton 11 is filled in the gaps between the frameworks and is fixed on the wall through expansion bolts and fixing clips.

[0022] Preferably, the basic framework layer 10 is connected and fixed through expansion bolts and fixing clips, and sound insulation cotton 11 is filled in the gaps between the grid-shaped keel structures. While improving the stability of the wall, it also improves the sound insulation ability of the wall.

[0023] As Figure 3 shown, the sound insulation microporous partition layer 20 adopts a layered composite structure, including an inner gypsum board 21, a sound insulation felt 22, a microporous partition 23, and an outer gypsum board 24. The four-layer structure of the sound insulation microporous partition layer 20 is fixed and connected through screws and fixing frames.

[0024] Preferably, the sound insulation microporous partition layer 20 adopts a layered composite structure, including an inner gypsum board 21, a sound insulation felt 22, a microporous partition 23, and an outer gypsum layer 24; each layer is fixed through screws and special clamps. Among them, the sound insulation felt 22 itself has extremely high sound insulation effect, and the microporous partition 23 contains micropores inside, which can well absorb and convert sound energy, thus improving the sound insulation effect.

[0025] As Figure 4 shown, the vacuum thermal insulation layer 30 is a hollow rectangular plate. The vacuum thermal insulation layer 30 includes an outer layer 31 and an inner layer 32. The outer layer 31 adopts a vacuum thermal insulation board, and the inner layer 32 is filled with aerogel 33. A small hole 34 is provided on the side of the vacuum thermal insulation board, and the inner layer 32 is evacuated through the small hole 34 on the side of the vacuum thermal insulation board.

[0026] Preferably, the vacuum thermal insulation layer 30 includes an outer layer 31 and an inner layer 32. The outer layer 31 adopts a vacuum thermal insulation board, and the inner layer 32 is filled with aerogel 33. A small hole 34 is provided on the side of the vacuum thermal insulation board, and the inner layer 32 is evacuated through the small hole 34 on the side of the vacuum thermal insulation board. It needs to be placed outside the sound insulation microporous partition layer 2 and sealed and fixed by using special sealing strips and fixing clips. The aerogel filled in the inner layer has excellent adsorption performance and heat insulation performance, which can effectively reduce the heat loss caused by the temperature difference between indoors and outdoors, thus achieving the effect of heat preservation.

[0027] As Figure 5 shown, the external protective layer 40 adopts a multi-layer composite structure. A waterproof and breathable membrane is provided between the external protective layer 40 and the vacuum insulation layer 30. The external protective layer is fixed and connected to the outside of the vacuum insulation layer through screws and sealing washers.

[0028] Preferably, in order to protect the internal structure of the thermal and sound insulation wall from being affected by external factors, the external protective layer 40 adopts a multi-layer composite structure. A waterproof and breathable membrane 41 is provided between the external protective layer 40 and the vacuum insulation layer 30. It needs to be installed on the outside of the vacuum insulation layer 30 and is connected and fixed through screws and sealing washers. The high-strength composite material not only further improves the stability and firmness of the external protective layer 40, but also improves the overall durability. Moreover, the waterproof and breathable membrane can also keep the inside of the thermal and sound insulation wall dry, improving the waterproof performance of the wall.

[0029] Preferably, each layer of the prefabricated thermal and sound insulation wall is installed on the gap of the upper layer, and each layer of the thermal and sound insulation wall is connected by screws or expansion bolts, improving the reliability and stability of the overall structure.

[0030] In this embodiment, the keel structure of the basic frame layer 1 is fixed to the wall through expansion screws, and then the cut sound insulation cotton 11 is filled into the gaps of the keels. After completing the basic frame layer, the inner gypsum layer 21 of the sound insulation microporous partition layer 20 is placed on the outside of the basic frame layer 10. Then, the sound insulation felt 22 is placed at the gaps of the inner gypsum layer 21. Subsequently, the microporous partition board 23 with small holes is placed on the outside of the sound insulation felt 22. Finally, the outer gypsum layer 24 is placed on the outside of the microporous partition board 23. The sound insulation felt 22 itself has excellent sound insulation effect. On this basis, the microporous partition board 23 that can absorb sound wave energy is added to further enhance the sound insulation effect. Screws and fixing jigs are needed to connect and fix each layer of the sound insulation microporous partition layer 20. After being fixed, it is connected to the basic frame layer 10 through screws. The inner layer 32 of the vacuum insulation layer 30 is filled with aerogel, and the inner layer 32 is evacuated through the small holes 34 on the side of the vacuum insulation layer 30. After the treatment, it is sealed, fixed and connected through special sealing strips and fixing clips. Aerogel has strong heat insulation ability and can effectively avoid temperature loss. After connecting the vacuum insulation layer, the waterproof and breathable membrane is attached to the surface of the vacuum insulation layer. Finally, the external protective layer 40 is fixed through screws and fixing washers, and the fixed external protective layer 40 is connected to the outside of the vacuum insulation layer 30.
