technical field

The utility model relates to the technical field of sound-insulating panels, in particular to a sound-insulating panel for buildings.

Background technique

Sound insulation board is a kind of board commonly used in construction. It is usually used to prevent the transmission of sound and eliminate noise. Common sound insulation boards are filled with shock-absorbing materials between two hanging boards, and the sound vibration is passed through the hanging board. The board and the shock-absorbing material are used to absorb and achieve the purpose of sound insulation. However, this structure is extremely unstable and will be deformed when squeezed, which will reduce the sound-absorbing effect of the shock-absorbing material. At the same time, a single shock-absorbing material will make the sound-absorbing structure single. Not good, so we propose a sound-insulating board for construction.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a sound-insulating board for construction, including a soft board 1 on the inner wall, facing the direction of the sound source, and initially absorbing sound waves, and the soft board 1 on the inner wall The surface is attached to the hanging steel plate 2, and the inner wall soft plate 1 is combined and hung to support the weight of the entire plate. The lower surface of the hanging steel plate 2 is attached to the honeycomb glass layer 7, and the internal honeycomb structure is used for sound and shock absorption. To achieve the effect of noise reduction, the lower surface of the honeycomb glass layer 7 is pasted with the first spacer steel plate 9 to carry out the weight layered load, and realize the multi-density change of the multi-layer material, and the lower surface of the first spacer steel plate 9 carries a box of sound-absorbing sponge Layer 3 is used for sound absorption and noise reduction through the irregular transmission of vibration through the mesh structure inside the sponge. The lower surface of the sound-absorbing sponge layer 3 is attached to the second interval steel plate 10, and the lower surface of the second interval steel plate 10 is attached to the sound-absorbing foam. Layer 5 is used for shock absorption, sound absorption and noise reduction through internal air bubbles. The lower surface of the sound-absorbing foam layer 5 is bonded to the third spacer steel plate 11, and the lower surface of the third spacer steel plate 11 is bonded to the tempered glass layer 4 to increase the compression resistance of the internal structure. Ability, the lower surface of the tempered glass layer 4 is attached to the outer wall steel plate 12 to protect the exterior of the entire sound insulation board.

Specifically, between the hanging steel plate 2 and the first spacing steel plate 9, between the first spacing steel plate 9 and the second spacing steel plate 10, between the second spacing steel plate 10 and the third spacing steel plate 11, the third spacing Between the steel plate 11 and the outer wall steel plate 12, a connection support column 6 is provided to support the space structure of the hanging steel plate 2, the first spacer steel plate 9, the second spacer steel plate 10, the third spacer steel plate 11 and the outer wall steel plate 12. To avoid extrusion and deformation of the internal shock-absorbing material when under pressure, the connecting support columns 6 are evenly distributed in a staggered manner, and the transmission of sound between the connecting support columns 6 is avoided through the staggered distribution.
