Description

Technical Field

[0001] The utility model relates to the technical field of silent bottom plates, in particular to an ultra-silent bottom plate with a sandwich structure. Background Art

[0002] Existing composite soundproof panels are mostly made of wood materials. During the production process, many harmful substances will remain inside the composite soundproof panels, which will cause harm to the human body and are not environmentally friendly and healthy. In addition, current composite soundproof panels mostly adopt a single-layer structure, and the sound insulation effect is not ideal.

[0003] After searching the Chinese patent with publication number CN215435439U, a multi-layer composite sound-proof board for home use is disclosed. By providing a first polyester board in combination with a second polyester board and a third polyester board, the sound insulation effect of the sound-proof board can be effectively increased, and the sound insulation effect of the sound-proof board is more superior. The multi-layer superposition of polyester boards can improve the overall strength of the sound-proof board. Due to the special material of the sound-proof board, no harmful substances will remain inside the sound-proof board, avoiding the problem that the sound-proof board is not environmentally friendly and easily causes harm to the human body. By providing a first sound insulation layer in combination with the second sound insulation layer, the sound insulation effect of the sound-proof board can be effectively improved, and the sound insulation effect of the sound-proof board is more superior.

[0004] Based on the above search and combined with the prior art, it was found that the above patent has certain defects.

There is no corresponding clip-on structure in the front and back, which easily leads to sound insulation gaps, resulting in poor sound insulation performance. In addition, there is a lack of double protection structure, and stability cannot be guaranteed, which reduces the use efficiency of the ultra-quiet baseboard. Utility Model Content
