Noise reduction structure for building outer wall
The invention relates to the technical field of buildings, and discloses a noise reduction structure for a building outer wall. The noise reduction structure comprises a mounting frame, a protective plate and a fixing frame, a clamping groove is formed in the upper surface of the mounting frame, a clamping block is fixedly connected to the lower surface of the mounting frame, and a mounting grooveis formed in the front face of the mounting frame; and a sound absorption cotton plate, a damping noise reduction layer, a honeycomb noise reduction plate and a rock wool plate are sequentially arranged in the mounting groove from inside to outside, and the protective plate is in threaded connection with the mounting frame through fixing bolts. According to the noise reduction structure for the building outer wall, through the arrangement of the sound absorption cotton plate, the damping noise reduction layer, the honeycomb noise reduction plate and the rock wool plate, in the external noisetransmission process, primary noise reduction is conducted through the rock wool plate, and then external noise enters the honeycomb noise reduction plate, is transmitted to sound guide holes throughsound absorption grooves and then is transmitted into noise reduction grooves; and noise is mutually transmitted in the noise reduction grooves and sound guide pipes to be reduced, part of the noise enters the damping noise reduction layer, and the purpose of efficient vibration and noise reduction can be achieved by combining a small amount of damping materials in the damping noise reduction layer.
本发明涉及建筑技术领域，且公开了建筑物外墙用降噪结构，包括安装架、防护板和固定架，安装架的上表面开设有卡槽，安装架的下表面固定连接有卡块，安装架的正面开设有安装槽，安装槽从内向外依次设置有吸音棉板、阻尼降噪层、蜂窝降噪板和岩棉板，防护板通过固定螺栓与安装架螺纹连接。该建筑物外墙用降噪结构，通过吸音棉板、阻尼降噪层、蜂窝降噪板和岩棉板的设置，当外界噪音传递过程中首先经过岩棉板进行一次降噪，然后进入蜂窝降噪板，经过吸音槽传递到导音孔然后传递到降噪槽内，噪音在降噪槽和导音管内相互传递进而消减，部分噪音进入阻尼降噪层内，在阻尼降噪层内结合少量阻尼材料可实现高效率减振降噪的目的。
