Description

Vibration/noise reduction element

Technical Field

The utility model belongs to the technical field of the building element, concretely relates to vibration/noise reduction component.

Background

With the popularization of multi-storey houses, the vibration noise in buildings also becomes a main factor disturbing people's lives. Among them, the ceiling, floor and wall of a building are all the media for transmitting noise, so how to enhance the anti-seismic performance between the keel and the frame becomes the focus of research nowadays.

The contents of the utility model

The to-be-solved technical problem of the utility model is that the vibration noise in the building has become a main factor puzzling people's life. Among them, the ceiling, floor and wall of a building are all the media for transmitting noise, so how to enhance the anti-seismic performance between the keel and the frame becomes the focus of research nowadays.

In order to solve the problem, the utility model provides a vibration/noise reduction component utilizes damping, the energy-absorbing characteristic of damping rubber, settles between fossil fragments and wall body, makes to realize the flexible coupling between fossil fragments and the wall body frame to reach vibration/noise reduction's effect.

In order to achieve the above purpose, the utility model is mainly realized by the following technical proposal: a shock absorption and noise reduction element comprises damping rubber, a galvanized clamp and a galvanized rivet, wherein the damping rubber is in a screw-shaped structure, a plurality of columnar bulges are arranged on the outer surface of an expanded end part of the damping rubber, the expanded end part is abutted against a wall body, certain buffering can be formed through the bulges, and when vibration occurs, the shock absorption and noise reduction element is better than that of a whole piece of rubber, so that the noise reduction effect is better; the column body of the damping rubber is provided with external threads, and the external threads are connected with the plate body of the galvanized clamp through threads, so that the position of the galvanized clamp is adjusted; the damping rubber is internally provided with connecting holes penetrating through two ends and used for being connected with the galvanized rivets; the damping rubber is connected with a hole in the center of the galvanized clamp through the external thread of the column body; the galvanized clip comprises a plate body and clips at four corners of the plate body, the clips are in a hook shape, the end parts of the clips are in arc-shaped structures, and grooves are formed in the upper parts of the clips and are used for being connected with the keels; the galvanized rivet is connected with the connecting hole of the damping rubber, the galvanized clip is fixed with the damping rubber, the inside of the galvanized rivet is also provided with mounting holes penetrating through two ends, and the damping rubber is fixed with a wall body through a connecting piece (such as a rivet).

Further, fossil fragments are the trapezium structure, and its bottom has the installed part of extension, and with the recess phase-match of checkpost, need not rivet connection, direct joint, easy to assemble saves the manual work, and four feet all hook fossil fragments consequently more firm moreover.

Furthermore, the damping rubber is made of rubber materials, so that the damping effect is good.

Furthermore, the galvanized clips and the galvanized rivets are made of carbon steel with galvanized surfaces, so that the structure is more stable.

Vibration and noise are transmitted to the keel from the outside and then transmitted to the clamp, and energy received by the wall body or the frame is greatly reduced after the energy is absorbed through the flexible connection of the elastic damping rubber. On the contrary, after vibration and noise from the wall or the frame are absorbed by the flexible connection of the elastic damping rubber, the energy received by the keel and the external decorative material is greatly reduced.

The utility model discloses following beneficial effect has:

1. the damping rubber has the characteristics of shock absorption and energy absorption, has good offset effect on low-frequency and medium-frequency shock, and has good buffering and inhibiting effects on sound waves and solid source shock, so that the effects of shock absorption and noise reduction are achieved.

2. The present element withstands compression from vertical and a 60 degree angle of inclination around, each shock absorber having a maximum load of 16.3 KGs.

3. The contact surface of damping rubber and wall body has the arch, can form certain buffering through the arch, when taking place vibrations, better than the shockproof effect of a whole piece of rubber to noise reduction effect is better.
