Sound reduction wall body sectional material structure

Abstract

The invention provides a sound reduction wall body sectional material structure and relates to a wall body structural material. At least one racket-shaped protrusion clamp strip (4) is arranged on thefront portion face of a square pipe (9); protruding C-shaped grooves (5) are formed in the back faces of face sound reduction plates (6); and protruding faces (11) of one sides of a plurality of backsectional materials (1) are connected with grooves (8) of the adjacent back sectional materials in a clamped mode; the racket-shaped protrusion clamp strip of each back sectional material is connected with the C-shaped groove of the corresponding face sound reduction plate in a clamped mode, a double-protrusion corner (14) is arranged on one side of a plate body (13) of each face sound reductionplate, the other side of each plate body is provided with a single-protrusion corner (15), and the double-protrusion corners on one sides of the plate bodies are clamped to the single-protrusion corners of the other sides of the adjacent plate bodies; and sponge strips (3) are arranged in cavities between every two racket-shaped protrusion clamp strips. According to the sound reduction wall body sectional material structure, the gaps between the face sound reduction plates are utilized to absorb low-frequency noise, and the sponge strips absorb the sound entering between every two racket-shaped protrusion clamp strips.

Description

【Technical field】 [0001] The invention relates to a wall profile, in particular to a sound-absorbing wall profile structure. 【Background technique】 [0002] It is known that with the emergence of a large number of high-rise buildings in new urban areas, or the construction of a large number of commercial and residential buildings in new urban areas and old urban renovations, transformers, water pumps, central air-conditioning extensions, and heating booster pumps for supporting facilities are also used in large quantities. , some of these devices are installed in the machine room on the floor, and the vibration can be reduced by setting a shock-absorbing support, but the sound cannot be handled, especially in the dead of night, which has a great impact on people with poor sleep quality, because these devices Most of the emitted noise is low-frequency noise. The main difference between low-frequency noise and high-frequency noise is that high-frequency noise can rapidly atten...

Problems solved by technology

[0002] It is known that with the emergence of a large number of high-rise buildings in new urban areas, or the construction of a large number of commercial and residential buildings in new urban areas and old urban renovations, transformers for supporting facilities , Water pumps, central air-conditioning extensions, heating booster pumps, etc. are also widely used. Some of these equipment are installed in the machine room on the floor. People with poor sleep quality will have a great impact, because most of the noise emitted by these devices is low-frequency noise. Attenuation, such as a point source of high-frequency noise, can be reduced by 6 decibels for every 10 meters distance
