Felt cloth sound insulation board

Abstract

The invention provides a felt cloth sound insulation board, and relates to the field of sound insulation boards. The sound insulation board based on felt cloth comprises a supporting plate, one side of the supporting plate is fixedly connected with a sliding groove, the upper end and the lower end of the inner side of the sliding groove are slidably connected with an upper adhesion plate and a lower adhesion plate correspondingly, the other side of the upper adhesion plate is provided with upper glass cement, and the lower side of the upper adhesion plate is rotationally connected with a second threaded rod through a second rotating shaft; and the bottom end of the second threaded rod is in threaded connection with the inner side of the fixing groove, the left side of the fixing groove is fixedly connected to the inner side of the sliding groove, and lower glass cement is arranged on the other side of the lower adhesion plate. The felt cloth and the sound insulation board are divided into two independent bodies which can be simply detached, the function that the felt cloth on the surface can be replaced and cleaned after being stained is achieved, then an insect expelling layer, a fireproof layer and a damp-proof layer are additionally arranged in felt sound insulation cloth, and the effect that the felt cloth sound insulation board has other functions while achieving sound insulation is achieved.

Description

Technical field [0001] The present invention relates to the field of soundproofing, and is specifically a felt cloth. Background technique [0002] The soundproof board is a sector acting on a sound insulation. There are buildings sound insulation and structures. The soundproof board is not a sound of all frequencies, and the object has an inherent resonant frequency, and the sound of the resonant frequency of the object is significantly reduced. The soundproof panel has the difference between the acoustic acoustic and the vibration sound. The air acoustic soundproof board, that is, blocking a plate that is propagated in the air. The vibration sound toneboard is blocking a sheet and system of sound propagated in rigid members such as steel concrete monolithic houses. [0003] At present, the problem of capping is difficult to replace after the surface of the felt cloth is used in the presence of the felt cloth, and the felt cloth soundproofboard function is single, and there is n...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a felt cloth sound insulation board, which solves the problem that the felt cloth is dirty and difficult to replace when it is used, and secondly solves the problem that the felt cloth sound insulation board can only silence sound, has no other functions, and has a single performance
