Hanging structure

Abstract

The invention discloses a hanging structure. The hanging structure is used for hanging a sound absorption wedge or a sound absorber on the top face of a building, the hanging structure comprises a T-shaped back frame, a leveling straight rod, a suspension sliding rail, a safety hook and a damping anti-skid rubber sleeve, wherein the T-shaped back frame is fixedly connected with the top face of thebuilding, the leveling straight rod is horizontally connected to the T-shaped back frame, the suspension sliding rail is fixedly connected to the leveling straight rod, the safety hook is fixed to the base portion of the sound absorption wedge or the sound absorption body, and the damping anti-skid rubber sleeve is sleeved on the safety hook; and the safety hooks and the suspension sliding railsare mutually hooked and combined through respective hook parts to finish the suspension of the sound absorption wedges or the sound absorbers on the top surface of the building. The suspension structure has shockproof, damping and anti-slip functions, can effectively prevent a suspended sound absorption wedge or a suspended sound absorber from falling off, effectively blocks sound and vibration propagation paths formed by rigid connection of the safety hook and the suspension sliding rail, guarantees the acoustic effect, and meanwhile, the safety of the sound absorption wedges or the sound absorbers and equipment and personnel in installation places of the sound absorption wedges or the sound absorbers is ensured.

Description

technical field [0001] The invention relates to a suspension structure, in particular to a suspension structure for suspending a sound-absorbing wedge or a sound-absorbing body on the top surface of a building, and belongs to the technical field of acoustic equipment manufacturing and installation. Background technique [0002] In terms of creating an ultra-quiet acoustic experiment environment or preventing noise pollution, sound-absorbing wedges or sound-absorbing bodies are required. [0003] The sound-absorbing wedge is a wedge-shaped sound-absorbing body with a high sound-absorbing coefficient designed to achieve a gradual transition of the acoustic impedance between the air and the sound-absorbing material, and to obtain a good impedance matching and sound-absorbing effect. . [0004] The sound-absorbing wedge consists of a base and a split. The base is the part with the same section at the bottom, and the split is the part where the cross-section gradually increases ...

AI Technical Summary

Problems solved by technology

[0008] In the prior art, there is no anti-shock and anti-slip function between the hook and the slide rail for hanging the sound-absorbing wedge or sound-absorbing body. However, in the aeroacoustic testing environment and noise pollution prevention and control environment, there is often airflow erosion. , pulsation, vibration and resonance, etc. Under the action of these phenomena, the hook of the sound-absorbing wedge or sound-absorbing body may slip off from the long slide rail at any time, causing damage to the sound-absorbing wedge or sound-absorbing body or even personal property. harm
