Combined multi-stage noise reduction device for building construction
The invention relates to the technical field of noise reduction for building construction, and discloses a combined multi-stage noise reduction device for building construction. The device is characterized in that a ventilation net is arranged on the front surface of a box body, limiting grooves are formed in the positions, above and below the ventilation net, of the front surface of the box body,a sound collection assembly capable of being transversely folded along the box body is connected to the front side of the box body, the bottom of the box body is connected with supporting assemblies,and a sound absorption assembly is arranged in the box body. According to the device, noise generated in the construction process can be collected through the sound collection assembly, so that the noise diffusing area is reduced; the width of the sound collection assembly is adjustable so that the sound collection range can be adjusted, and the use is convenient; the noise reduction device can be stably supported through the supporting assemblies so that the noise reduction device can be prevented form toppling over in the use process; and the inclination angles between first supporting rodsand second supporting rods are adjustable so that actual placement requirements can be easily met.
本发明涉及建筑施工降噪技术领域，公开了一种建筑施工用的组合式多级降噪装置，所述箱体的前表面开设有透气网，且箱体的前表面位于透气网上下方位置均开设有限位槽，所述箱体的前侧还连接有可延其自身横向折叠的集音组件，且箱体的底部连接有支撑组件，所述箱体的内部还设置有吸音组件。本发明通过集音组件可以对施工过程中产生的噪音进行收集，降低了噪音向周围扩散的面积，而且该集音组件的宽度可调，使得集音范围得到了调节，方便使用，通过支撑组件可以对该降噪装置起到稳固支撑的目的，防止其在使用过程中出现倾倒现象，而且第一支撑杆和第二支撑杆之间的倾斜角度可调，易于实际的摆放需要。
