Description

Technical Field

[0001] The utility model belongs to the field of sound insulation boards, in particular to a stainless steel sound insulation building board. Background Art

[0002] A lot of noise is generated during factory production and construction on construction sites. In order to reduce the noise, the current solution is to set sound insulation panels at the boundaries of different areas. The sound insulation panels can absorb noise and prevent it from spreading. Among them, wooden sound insulation panels and plastic sound insulation panels are the most common. Their structure includes multiple layers of different types of panels stacked on each other and sound-absorbing cotton, which can achieve both sound insulation and heat insulation functions. However, the above materials have the problems of short service life and easy damage, and cannot be applied to construction sites and outdoors with harsh working conditions. Therefore, there are also metal sound insulation panels on the market. Metal sound insulation panels are mainly made of aluminum plates, steel plates and other materials. Its advantages are high strength and good durability, and it can withstand large external force impact without deformation.

[0003] However, the internal sound cavity design of existing metal sound insulation panels is defective, resulting in poor sound absorption effect, and the sound absorption effect is completely dependent on the quality of the sound-absorbing cotton. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel sound insulation building board which optimizes the internal sound cavity.

[0005] To achieve the above-mentioned purpose, the utility model provides a stainless steel sound insulation building board, comprising: an outer layer plate, a bent plate and an inner layer plate stacked in sequence, the outer layer plate, the bent plate and the inner layer plate are all made of stainless steel, the outer layer plate is provided with a plurality of sound-absorbing holes that allow sound to enter, the bent plate is bent in a wave shape or a broken line shape, the bent plate is provided with a plurality of sound-absorbing holes that allow sound to enter, the inner layer plate is a flat panel, the gaps between the outer layer plate and the bent plate and between the inner layer plate and the bent plate are filled with sound-absorbing cotton, and the outer layer plate faces the side where noise is generated.

[0006] As an improvement to the above solution, the gap size on the side where the bent plate contacts the outer plate is larger than the gap size on the side where the bent plate contacts the inner plate.

[0007] As an improvement to the above solution, the positions where the bent plates are used to contact the outer plate and the inner plate are both flat.

[0008] As an improvement to the above solution, the thickness of the outer plate, the bent plate and the inner plate are all 1.5 mm, and the sound-absorbing holes distributed on the outer plate and the bent plate have the same layout.

[0009] As an improvement to the above solution, the outer layer plate and the bent plate, as well as the inner layer plate and the bent plate, are fixed by welding, and the welding positions are at the outer edges of the bent plates.

[0010] As an improvement to the above solution, a sealing strip is further included, which surrounds the outer edges of the outer plate, the bent plate and the inner plate.

[0011] This utility model has the following beneficial effects: The three-layer panel structure, when combined, possesses sufficient bending resistance, resulting in a stable and durable structure suitable for deployment in harsh working environments. The bent panels are designed to increase the structural strength of the panels while also creating cavities that can be removably inserted into the sound-absorbing cotton. Most sound first passes through the sound-absorbing holes in the outer panel, then through the sound-absorbing holes in the bent panel, where it is absorbed by the sound-absorbing cotton in two different cavities. Some sound waves are reflected by the inclined surface of the bent panel, thereby enhancing the sound absorption of the cotton. BRIEF DESCRIPTION OF THE DRAWINGS
