Sound-absorption, heat-insulation and fireproof building wall

Abstract

The invention discloses a sound-absorption, heat-insulation and fireproof building wall which comprises a wall and an inorganic material heat-insulation layer. The inorganic material heat-insulation layer is mounted on the outer side of the wall, a fireproof layer is arranged between the wall and the inorganic material heat-insulation layer, a sound-absorption plate is arranged between the fireproof layer and the wall, a facing layer is arranged on the side, which is far away from the fireproof layer, of the inorganic material heat-insulation layer, the inorganic material heat-insulation layer 3 is made of inorganic material micro-spheres which are coated on the surface of the side, which is far away from the wall 1, of the fireproof layer 4, and reinforcement meshes are arranged on the surfaces of two sides of the sound-absorption plate. The sound-absorption, heat-insulation and fireproof building wall has the advantages of sound-absorption, heat-insulation and fireproof properties.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a sound-absorbing, heat-retaining and fire-proof building wall. Background technique [0002] Any sound that hinders people's normal rest, study and work, and any sound that interferes with the sound that people want to listen to. In this sense, there are many sources of noise, such as the sound of cars on the street, the sound of talking in a quiet library, the sound of machines on a construction site, and the loud sound of neighbors' TV sets, all of which are noises. Elevators are indispensable equipment in super high-rise residences, especially in the residential structure with one elevator and two households, each household has at least one wall adjacent to the elevator shaft. During the use of the elevator, when the elevator car runs to the wall next to the elevator shaft, the noise is transmitted inward through the wall to the house, affecting people's normal rest or lif...

AI Technical Summary

Problems solved by technology

During the use of the elevator, when the elevator car runs to the wall next to the elevator shaft, the noise is transmitted inward through the wall to the house, affecting people's normal rest or life and entertainment. At present, the general building exterior walls use thermal insulation materials to effectively Prevent heat conduction, or use fireproof materials to improve the fireproof performance of the building's exterior walls, or paste sound insulation panels on the building's exterior walls to increase the sound insulation effect of the walls, but there is a lack of building walls that are both heat-resistant, fire-proof, and sound-proof
