A spring rubber vibration-isolation hanger for vibration and noise reduction of heating and ventilation pipes

Abstract

The invention relates to a spring rubber vibration-isolation hanger used for vibration reduction and noise reduction of heating ventilation pipes, which is installed on the indoor top of a building. The hanger includes a first frame, a vibration isolation pad laid on the inner wall of the first frame and tightly wrapping the abdomen of the heating ventilation pipe, and two sets of suspension vibration isolation components. The first frame includes a U-shaped pipe clip and a crossbeam located below the heating and ventilation pipe and fixedly connected to the opening end of the U-shaped pipe clip to form a closed frame structure with the U-shaped pipe clip. The suspension vibration isolation assembly includes an upper suspension rod, a spring vibration isolator and a lower suspension rod connected vertically in sequence. The invention can not only play a good role in vibration isolation and shock resistance for the whole heating and ventilation pipe, but also can play a good role in vibration isolation and noise reduction for the local air pipe, and is especially suitable for the main control room of the nuclear power plant and the film and television workstation, etc. It is suitable for occasions that have higher requirements for indoor equipment safety and acoustic environment.

Description

technical field [0001] The present invention relates to a hanger device for heating and ventilation pipes, in particular to a spring rubber for vibration and noise reduction of heating and ventilation pipes suitable for special indoor occasions with high requirements for shock resistance, vibration isolation and noise reduction Vibration isolation hanger. Background technique [0002] Central heating and ventilation systems are installed in large commercial buildings, nuclear power plant main control rooms, film and television workstations, large commercial buildings, etc. to maintain indoor temperature and air circulation, and provide indoor staff with a comfortable and safe working environment. However, the vibration noise and anti-seismic safety issues of heating and ventilation pipes have long plagued people. Wind pressure fluctuations cause self-breathing vibration and noise radiation of the air duct, fan vibration causes vibration and noise of the air duct and its han...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the supporting hanger does not adopt any vibration isolation and noise reduction structures or components, the entire structural components are rigidly connected, and the structural stiffness is fixed and cannot be adjusted. Therefore, it can only ensure the structural integrity of the heating and ventilation pipe system under normal working conditions. Safety, but can not play the role of vibration isolation, earthquake resistance, noise reduction;

[0005] 2. The spring support hanger, variable spring support hanger and rubber support hanger have certain functions of vibration isolation, shock resistance and noise reduction for the whole system, but because they do not have any structure in the abdomen of the air duct to limit the local vibration of the air duct Or components, therefore, they cannot effectively reduce the noise caused by the local breathing vibration of the pipe wall under the fluctuation of internal pressure of the thin-walled air duct
