Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing units, in particular to an inter-beam sound-absorbing unit. Background Art

[0002] The beam silencer is a device used for sound insulation and silencing, usually used between beams and slabs of buildings to reduce the transmission of sound and the diffusion of noise. It can effectively reduce the propagation of sound and provide a better acoustic environment. The silencer units currently on the market are not array-mounted. While ensuring the silencing of the air intake, they are somewhat lacking in air intake volume and air intake resistance, which needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: an inter-beam silencer unit, comprising a frame, a noise reduction steel beam is fixedly installed on the inner side of the frame, an organic tower air inlet surface is provided on the surface of the frame, air inlet silencer units are fixedly installed on the upper and lower ends of the noise reduction steel beam, an inner-beam silencer unit is arranged on the inner side of the noise reduction steel beam, self-tapping screws are arranged on the inner side of the noise reduction steel beam, and angle steel is welded and installed on the inner side of the noise reduction steel beam.

[0005] Preferably, the number of the mechanical tower air inlet surfaces is two groups and they are symmetrically distributed at the upper and lower ends of the surface of the frame. Here, by setting two groups of mechanical tower air inlet surfaces, a relatively excellent load-bearing effect can be achieved in conjunction with the noise reduction steel beam, thereby improving the noise reduction effect of the air inlet silencer unit.

[0006] Preferably, the air inlet silencer units are arranged in an array on the inner side of the air inlet surface of the power tower. Here, by providing an array of air inlet silencer units, the air volume can be evenly dispersed during operation, so that the noise reduction effect is more excellent.

[0007] Preferably, the beam-inside silencer unit is fixedly installed with the noise reduction steel beam by self-tapping screws. Here, by using self-tapping screws to connect the beam-inside silencer unit and the noise reduction steel beam, not only the stability of the beam-inside silencer unit after installation can be improved, but also a higher bearing capacity can be achieved during the air intake silencer operation.

[0008] Preferably, the noise reduction unit in the beam is fixedly installed by self-tapping screws and angle steel. Here, by setting the angle steel, the noise reduction unit in the beam can be fixed to the noise reduction steel beam with the self-tapping screws, and a higher bearing capacity can be provided.

[0009] Preferably, the specifications of the noise reduction steel beam match the air inlet silencer unit. Here, by providing matching noise reduction steel beams and air inlet silencer units, the installation process can be made more convenient and the wind resistance can be more outstanding.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] In the utility model, by setting a frame, a noise reduction steel beam, an air inlet surface of a mechanical tower, an air inlet silencer unit, a silencer unit in a beam, self-tapping screws, and an angle steel, on the one hand, it ensures that the overall noise reduction volume of the air inlet silencer will not be reduced, and on the other hand, it opens up the air flow channel, thereby increasing the air inlet volume and reducing the air inlet resistance to the greatest extent, thereby playing a role in saving the energy efficiency of the equipment.
