Description

Technical Field

[0001] This utility model relates to the field of noise isolation technology, specifically to a noise isolation mechanism for building construction. Background Technology

[0002] Compared to industrial or traffic noise, construction noise is characterized by its greater intensity. Many construction equipment, such as pile drivers, hydraulic breakers, and concrete mixers, generate extremely high noise levels during operation, far exceeding environmental standards. Without intervention, this can have a serious impact on the lives and health of the surrounding residents. Therefore, it is necessary to build noise isolation structures around the construction site to reduce the spread and impact of noise.

[0003] The prior art discloses a green building construction noise isolation device with application number CN201920363394.5. This utility model uses a noise reduction box installed inside the shell to isolate and reduce construction noise. However, the height of the shell and the noise reduction box is fixed. As construction continues, the noise source may rise, causing the noise reduction box at that height to reduce or lose its noise isolation effect. Furthermore, this structure is not easy to stack and build at a high place for noise isolation operations. Therefore, its applicability is poor and its practicality is relatively general. Thus, those skilled in the art have proposed a construction noise isolation mechanism. Utility Model Content

A connecting shaft seat is connected to one end of the assembly screw, and an assembly plate is fixedly connected to the bottom surface of the connecting shaft seat. Several fixing pins are evenly welded to the side wall of the assembly plate. Several through holes are evenly opened on the side wall of the installation groove.

[0006] Furthermore, a sound-absorbing plate box is fixedly installed in the center of the inner cavity of the isolation plate box, and a first sound-absorbing cotton is fixedly installed on one side wall of the sound-absorbing plate box and the inner wall of the isolation plate box. A sound-insulating felt is fixedly installed between the other side wall of the sound-absorbing plate box and the inner wall of the isolation plate box. Several sound-absorbing nozzles are evenly installed on the side of the isolation plate box near the construction site. Several noise reduction channels are evenly opened on one side of the sound-absorbing plate box. Several echo baffles are welded into the inner cavity of the sound-absorbing plate box, and a second sound-absorbing cotton is fixedly installed between the echo baffles.

[0007] Furthermore, fixing blocks are symmetrically welded to both sides of the mounting base plate, and fixing bolts are screwed onto the fixing blocks.

[0011] Furthermore, the diameter of the fixing pin is smaller than the inner diameter of the connecting hole.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a construction noise isolation mechanism, which has the following beneficial effects: (1) This utility model can achieve rapid ground fixation of equipment by using the installation base plate, fixing block and fixing bolt.

[0013] (2) The core of the sound insulation structure of this utility model is the built-in sound-absorbing plate box. After the noise enters the box body through the sound-absorbing nozzle, it is initially absorbed by the first sound-absorbing cotton, the noise reduction channel is refracted and dissipated multiple times, the internal echo baffle and the second sound-absorbing cotton are further attenuated, and finally the sound insulation felt completes the final isolation. This multi-level progressive sound insulation design greatly improves the noise blocking effect. Attached Figure Description
