Suspension type anti-vibration member

Abstract

Provided is a suspension type anti-vibration member, capable of meeting the demand for small-sized and light anti-vibration member and ensuring the anti-vibration effect by preventing the contact between the anti-vibration material and the anti-vibration member body even if the position of the inserts and the position for setting vibration device stagger with each other. The suspension type anti-vibration member comprises: an anti-vibration body (suspension member box) which, arranged at the midway (between the upper hanging bolt and the lower hanging bolt) of the suspending bolt of a vibration device for producing vibration during suspension, bears the load of the above mentioned vibration device, an anti-vibration material (tapered spiral spring or tapered rubber spring) which, arranged between the upper edge and the lower edge of the anti-vibration member body, is used for absorbing the vibration of the vibration device, and two elastic members (rubber cap and rubber boot) arranged between the anti-vibration material and the anti-vibration member body as well as between the anti-vibration material and the suspension bolt. The suspension type anti-vibration member prevents the vibration spreading of the vibration device, with the anti-vibration material in a shape of tapered table.

Description

technical field [0001] The present invention relates to a suspension-type anti-vibration member that is installed on suspension bolts for suspending vibrating equipment such as air-conditioning equipment and / or supply and drain pipes, pipes for supplying and exhausting, etc., to prevent vibration transmission of the vibrating equipment, and more specifically, relates to preventing A technology in which the anti-vibration material of the suspension-type anti-vibration part comes into contact with the main body of the anti-vibration part to impair the anti-vibration effect. Background technique [0002] In structures such as buildings, air-conditioning equipment, water supply and drainage pipes, pipes and / or pipes for air supply and exhaust, etc. are suspended from structural bodies such as upper floors and / or roof support materials with suspension bolts. In addition, in such air-conditioning equipment, water supply and drainage pipes, pipes and / or pipes for supply and exhaust...

AI Technical Summary

Problems solved by technology

[0003] There is a problem that the vibration generated from the vibrating equipment is transmitted to the main body of the structure such as the floor plate through the suspension bolts, and the damage caused by the vibration and / or vibration sound is generated in the entire building

[0005] However, in the ceiling suspension type vibration isolator A described in Patent Document 1, although the equipment side suspension bolts 21 can be prevented from contacting the suspension body 10, in order to prevent the compression coil spring 14 as the vibration isolating material from contacting the vibration isolator body. contact with the hanger main body 10, it is necessary to increase the cantilever distance of the unfavorable load bearing part 13 on the bending moment to obtain the distance between the hanger main body 10 and the compression coil spring 14, which exists (1) in the space in the narrow ceiling The problem of miniaturization and light weight requirements of anti-vibration parts

[0006] In addition, when the nut that stops the compression coil spring 14 to the equipment side suspension bolt 21 is turned, the compression coil spring 14 is located on the lower side than the nut, so (2) it cannot be rotated with an electric tool, and must be manually tightened. The installation of anti-vibration parts takes man-hours

[0007] In addition, when the installation-side suspension bolts 21 are installed obliquely, the compression coil spring 14 also moves up and down in an oblique state, so there are also (3) the telescopic displacement direction of the compression coil spring 14 deviates from the vertical up-down direction. Since there is an angle, harmful up-and-down vibrations cannot be efficiently attenuated, and the effect of vibration absorption is reduced.
