Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation, sound absorption and noise reduction, in particular to a lightweight wall structure with the functions of sound insulation, sound absorption and noise reduction. Background Art

[0002] With the development of science and technology, the progress of society, and the continuous improvement of living standards in modern residential areas, noise is indispensable in our living environment. Noise pollution has been plaguing our lives. It has become a major public hazard in modern life, and it is extremely harmful to children, the elderly, patients, and heart patients. In order to reduce noise, people's demand for sound-absorbing panels has also increased.

[0003] Existing wall systems offer poor sound insulation, sound absorption, and noise reduction. Noise causes significant distress and serious harm to people's daily lives, work, study, and mental well-being. Common wall insulation materials on the market can only be used in dry spaces; there are no soundproofing wall fillers suitable for use in wet spaces like bathrooms and showers. Furthermore, conventional wall materials are heavy, which can easily affect the structural load-bearing capacity and pose safety risks. Therefore, we propose a lightweight wall system that effectively insulates, absorbs, and reduces noise. Utility Model Content

[0004] The technical problem to be solved by the present invention is that wall sound insulation materials can only be used in dry spaces. In wet spaces such as bathrooms and shower rooms, there are no sound insulation wall filling materials that can be used. Conventional wall building materials have a large dead weight and are likely to affect the structural bearing capacity, causing safety hazards.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: providing a lightweight wall structure with sound insulation, sound absorption and noise reduction, comprising an original building wall, a bonding mortar leveling layer is provided on one side of the surface of the original building wall, an EPS polystyrene board is bonded to one side of the surface of the bonding mortar leveling layer, a plurality of unconnected holes are opened on the surface of the EPS polystyrene board, and one side of the surface of the EPS polystyrene board is covered with wire mesh;

[0006] A tile-specific adhesive is provided on one surface of the wire mesh, tiles are adhered to one surface of the tile-specific adhesive, and a treatment layer is provided between the wire mesh and the tile-specific adhesive.

[0007] Preferably, the treatment layer includes a cement mortar roughening treatment, the cement mortar roughening treatment is arranged on the surface of the wire mesh, the surface of the cement mortar roughening treatment is coated with a polyurethane waterproof layer, and the surface of the polyurethane waterproof layer is laid with a cement mortar protective layer.

[0008] Preferably, the size of the wire mesh is 10MM*10MM*1MM, and the wire mesh is woven from crisscrossing wires.

[0009] Preferably, the thickness of the polyurethane waterproof layer is 1.5MM, and the waterproof layer is made of polyurethane material and has a strong waterproof effect.

[0010] Preferably, the thickness of the cement mortar protective layer is 20MM, and the ratio of cement and water in the cement mortar protective layer is 1:3, ensuring that the water and cement in the cement mortar protective layer are mixed better, and the thickness of 20MM has stronger strength.

[0011] Preferably, the special adhesive for tiles is bonded to the surface of the cement mortar protective layer, and the special adhesive for tiles is used to facilitate bonding of tiles.

[0012] The beneficial effects of the utility model are as follows:

[0013] By setting the above structure, the utility model can enhance the penetration depth of sound by thickening the wall. The EPS polystyrene board material contains many holes without connectivity, and sound waves cannot penetrate deep into the material, so vibration and friction can achieve the effect of sound insulation. In addition, the EPS polystyrene board is light in material. Although the wall is thickened as a whole, the total weight of the wall is increased very little. Because of the use of waterproof technology, this method can also be used in various different spatial scenes, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
