Problems solved by technology

[0002] In the existing floor structure, once the neighbors, especially the upstairs residents, have a large knock and friction action, the vibration and noise generated in the upstairs room are easily transmitted to the downstairs through the wall panels, affecting the rest of the downstairs residents and affecting the safety of the neighbors. Serious disturbances in life, especially at night
The existing sound insulation structure used for floor slabs is only to lay sound insulation boards, but the existing sound insulation boards have poor sound insulation and shock isolation effects, and cannot effectively eliminate most of the noise and vibration generated upstairs, and will still have a large impact on the rest of the downstairs residents.

Abstract

The invention discloses an anti-floor-vibration device. The anti-floor-vibration device comprises a metal skeleton and a noise reduction device, wherein the metal skeleton includes an upper metal skeleton and a lower metal skeleton, the noise reduction device is located between the upper metal skeleton and the lower metal skeleton, the noise reduction device comprises a composite vibrating diaphragm, a first sound absorption layer and a gypsum layer which are sequentially arranged from top to bottom, the noise reduction device further comprises a sound acquisition sensor, a controller and an electric ceramic vibration sheet, the sound acquisition sensor is arranged on the upper surface of the composite vibrating diaphragm, the controller is connected with the sound acquisition sensor, andthe electric ceramic vibration sheet is connected with the controller and attached to the lower surface of the composite vibrating diaphragm. The anti-floor-vibration device is ingenious in structuraldesign, remarkable in noise reduction effect, and economical and practical.

Description

technical field [0001] The invention relates to the technical field of building noise reduction equipment, in particular to an anti-seismic building device. Background technique [0002] In the existing floor structure, once the neighbors, especially the upstairs residents, have a large knock and friction action, the vibration and noise generated in the upstairs room are easily transmitted to the downstairs through the wall panels, affecting the rest of the downstairs residents and affecting the safety of the neighbors. Life brings serious disruptions, especially at night. The existing sound insulation structure used for floor slabs is only to lay sound insulation boards, but the existing sound insulation boards have poor sound insulation and shock isolation effects, and cannot effectively eliminate most of the noise and vibration generated upstairs, and will still have a large impact on the rest of the downstairs residents. Impact. Contents of the invention [0003] The...
