Description

Sound proof wall

The present invention relates to a soundproof wall that is hypothesized to prevent noise around a construction or various civil works.

Various soundproof walls have been developed and used to prevent noise and safety accidents around new homes or industrial works, and around civil engineering works. Such soundproof walls are synthetic resins and are made of flat plates through a predetermined extrusion process. It is manufactured in a shape and supplied.

These soundproof walls have been installed in recent years due to their excellent installation and sound insulation effect, and the use of such soundproof walls has been arranged at equal intervals between inner and outer boards arranged at relatively narrow intervals and between the inner and outer boards. Spaces with sound absorbing materials are separated from each other by using diaphragms, and through-holes are connected to inner spaces with sound absorbing materials in the inner sheet, and both sides and inner and outer sides of the inner sheet are formed with male and female structures. The first and second binding elements, which are combined into two sets and joined together using a frame and a clamp, are provided and installed at a predetermined height along the circumference of the construction site to prevent safety accidents and prevent noise at the construction site. It will provide a fence for you.

However, the sound absorption of the soundproof walls is made of some sound absorbing materials filled in the space between inner and outer boards and exposed locally through the through-holes of the inner boards, and the contact area between the sound absorbing material and the noise is relatively small and the sound absorption is compared with the area of the sound absorbing material. The efficiency is extremely low, and thus there are many problems such as poor sound absorption and a low noise prevention effect.

In addition, the sound absorbing material is filled in the space between the inner and outer panels of the soundproof wall, so that no noise flows into the soundproof wall space, but is reflected back into the atmosphere, so that the effect of canceling noise due to continuous diffuse reflection in the space cannot be obtained. In addition, the noise reduction efficiency of the soundproof wall is low, and thus the productability is deteriorating.

In addition, the sound absorbing material embedded in the soundproof wall space is usually fixed by using an adhesive. When dismantling the soundproof wall, it is necessary to separate the heterogeneous sound absorbing material in the space. will be.

Another object of the present invention is to easily remove the sound absorbing material embedded in the soundproof wall space by a simple dismantling operation of the sound absorbing material, to provide a soundproof wall that is more convenient and recyclable in separating the sound absorbing material.

The object of the present invention is achieved by providing a soundproof wall that is hypothesized to prevent noise around the construction or various civil works, which is mutually isolated using barriers arranged at equal intervals between the inner and outer panels. The sound absorbing material has spaces built in each, and the inner plate has through holes connected to the space, and is connected to both sides and the center of the inner plate by a male-to-female structure with an adjacent side, and is joined using a skeleton and a clamp. A soundproof wall having a first binding element and a second binding element, wherein the sound absorbing material embedded in the space has a thickness less than half the width of the space, and a fixing element detachably installed in the through hole to push and fix the sound absorbing material to one side of the space. Including, the sound absorbing material is disposed biased to one side of the space by the fixing element so that the sound absorbing material between the inner plate material and the sound absorbing material A negative offset space is provided, which effectively eliminates noise by combining sound absorption and offset.

According to the soundproof wall according to the present invention, the sound absorbing material having a thickness less than half of the width of the space in the space between the inner and outer boards is built to one side by using a fixing element detachably installed through the through-holes and the sound absorption and space using the sound absorbing material By combining with the offset effect in the, it is effective to remove noise more efficiently and obtain a product with excellent sound insulation performance.

In addition, the present invention by simply removing the sound absorbing material embedded in the soundproof wall space by a simple dismantling operation of the sound absorbing material, there is an effect of improving the recyclability as well as convenience in the separation work of the sound absorbing material.

Next, an embodiment of the present invention will be described. 1 to 4 show a soundproof wall according to the invention in detail.

The present invention is to provide a soundproof wall that is hypothesized to prevent noise and safety accidents in the construction or renovation of a house or industrial site, and around a civil engineering site.

The sound barrier will be manufactured in the shape of a flat plate through a predetermined extrusion process into approximately synthetic resin.

In the figure, 100 is a sound barrier. The soundproof wall 100 is largely divided into a frame 120 and a plate body 140. First, the frame 120 is composed of approximately horizontal bars 120a and vertical bars 120b.

In addition, the plate body 140 is separated from each other by using the inner and outer plate members 142 and 144 disposed at relatively narrow intervals and the diaphragms 146 disposed at equal intervals between the inner and outer plate members 142 and 144. Each of the spaces 149 and 148 is embedded therein, and the inner plate 142 is provided with through holes 143 connected to the space 149.
