Description

{TEMPORARY SOUNDPROOFING WALL}

The present invention relates to a temporary sound barrier, more particularly, to a method of manufacturing a temporary sound barrier constructed on a construction site or the like by improving the degree of freedom of connection between unit sound barrier walls, thereby improving work flexibility and work efficiency, And to improve the recyclability and the like.

Generally, construction sites such as apartments and buildings, factories, and waste disposal sites divide the area of the construction site to prevent public accidents and prevent safety accidents caused by falling objects or falling objects. A hypothetical sound barrier is constructed in the form of a fence in order to block the construction noise and scatter dust as much as possible.

As the industry develops and the life becomes more and more abundant, the issue of ensuring comfort along with the convenience of human life is becoming a very important development policy by decreasing various environmental pollution now. In this way, while limiting many pollution factors for a comfortable life, the pollution that is most exposed to modern people and which must be reduced necessarily for a comfortable life is noise and dust pollution.

The places where such noise and dust are generated are various construction sites such as building new construction and reconstruction. In this construction site, noise of various kinds of machine noise occurs severely during construction, and such construction noise causes severe noise pollution in houses, offices, schools, etc. located near the site. In particular, when the construction site is located on the roadside, the construction noise is accompanied by the vehicle noise, which causes great stress to the people.

Accordingly, noise and dust generated in construction sites are blocked around construction sites such as apartments and new buildings, and a so-called hypodetic sound barrier is installed in the form of a wall during the construction period for the safety of pedestrians. Remove the hypothetical sound barrier.

These hypothetical soundproof walls have various materials and shapes such as steel, RPP, EGI, and AL. Particularly, a sound absorbing material is embedded between the front panel and the rear panel, which form a soundproof panel, a unit element of the soundproof wall. Is used as a hypothetical sound barrier.

In this connection, various methods have been proposed in Korean Patent No. 10-1730976, Korean Patent No. 10-0945461, Korean Patent No. 10-0930498, Korean Patent No. 10-0900344 and Korean Patent No. 10-0536826 Lt; / RTI >

However, the conventional hypodermic wall has a structural limitation in that it is difficult to assemble and construct a low sound-absorbing wall surrounding the construction site by connecting unit sound-absorbing walls to each other. There is a problem that the flexibility and efficiency of the work are poor when the sound barrier is installed and removed.

That is, the conventional hypodermic wall has an assembly structure in which the connection of the unit sound-absorbing walls is an assembly structure based on the male and female structures and is connected in a straight line without flexibly coping with the change in angle. Thus, It is necessary to make a connection between the soundproofing walls so that the soundproofing walls are smoothly bent so that the soundproofing walls can not be connected to the soundproofing walls in an ideal situation. The construction of the hypothetical sound barrier has a low degree of freedom of connection and takes a long time to be constructed or disassembled. Thus, the work efficiency is low and the flexibility of the work is deteriorated.

In addition, the existing hypothetical sound barrier wall is composed of a sound absorbing material which is filled in a space between the inner and outer plate materials and is locally exposed through the through hole of the plate material. The contact area between the sound absorbing material and the noise is relatively small, And thus there is a problem that the sound absorption effect is insufficient and the noise prevention effect is inferior. In addition, since the sound absorbing material is filled in the space between the inner and outer soundproof walls, the sound is not reflected into the soundproof wall space and is reflected again into the atmosphere, so that the effect of canceling the noise due to continuous diffuse reflection in the space can not be obtained , There is a problem that the noise removing efficiency of the soundproof wall is low and the product quality is deteriorated.

In addition, since the sound absorbing material embedded in the sound barrier wall is usually fixed using an adhesive agent, it is necessary to separate the sound absorbing material in the recycling time space after dismantling the sound barrier wall. However, there is a problem that the separation work of the sound absorbing material is very difficult, I think.

Meanwhile, a conventional hypothetical soundproof wall can be stacked and laid down while being managed and transported. Usually, a pedestal (not shown) is provided on both sides of the unit soundproof wall so that a gap is formed between the unit soundproof walls However, the existing hypothetical soundproofing wall has a problem in that warpage occurs due to self-loading due to the center portion thereof, and warpage phenomenon is particularly intensified in hot summer.

Korean Registered Patent No. 10-1730976 (registered date, April 21, 2017) Korean Patent No. 10-0945461 (registered date, Feb. 25, 2010) Korean Patent No. 10-0930498 (registered date, December 01, 2009) Korean Patent No. 10-0900344 (registered date, May 25, 2009) Korean Patent No. 10-0536826 (registered date, December 20, 2005)

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and it is an object of the present invention to provide a hypothetical sound insulation board which is designed optimally, and in constructing a hypothetical sound insulation wall surrounding the construction site, So that work flexibility and work efficiency can be improved when a hypothesis sound barrier is constructed.

It is another object of the present invention to provide a hypothetical sound barrier which facilitates the separation of the sound absorbing material during disassembly of the sound barrier wall and thus improves the recyclability of resources.

It is another object of the present invention to provide a hypothetical sound barrier which can be effectively prevented from warpage, which is supported by a pedestal and is deformed due to a self centering of a portion of a surface of a unit acoustic barrier wall having a gap.

In order to accomplish the above object, the present invention provides a hypothetical sound barrier for shielding noise, dust, and the like from being separated from a construction site by connecting unit sound insulation walls around various construction sites,

A rear panel having a plurality of holes formed on a surface thereof, a middle panel positioned between the front panel and the rear panel, and a rear panel disposed between the front panel and the rear panel, And a sound absorbing material disposed between the panel and the intermediate panel,

And a connecting member for connecting the unit sound absorbing walls with each other at predetermined angles is further provided between the unit sound absorbing walls connected adjacent to each other.

The hypothetical sound barrier of the present invention provides various effects as follows.

First, the hypothetical sound barrier wall according to the present invention is constructed by connecting the unit sound barrier walls to form a sound barrier which surrounds the construction site in the form of a fence, and thus the flexibility of connection between the unit sound barrier walls is high, do.

In other words, unlike the existing hypodetic sound barrier, the connection of the unit sound barrier walls can be variously made, and the connection angle of the assembly site can be adjusted smoothly according to the environment of the construction site, Sound barrier construction is effective.

In addition, the hypothetical sound barrier according to the present invention can increase the sound absorption efficiency and enhance the noise prevention effect as compared with the existing hypothetical sound barrier.

That is, according to the present invention, since the soundproof wall inner and outer plates are made to have a multi-layer structure, the sound absorbing material absorbs most of the noise in some of the layers and the noise that is not absorbed by some sound absorbing materials flows into the inner space , It is possible to increase the noise removal efficiency of the hypothetical sound barrier.

In addition, the temporary sound barrier wall according to the present invention takes a form in which the sound absorbing material embedded in the inner space of the unit sound absorbing wall is physically fixed by pressing the fixing member, not by a chemical bonding method using an adhesive, So that the recycling efficiency is improved, and so on.

Meanwhile, when the unit sound absorbing walls are stacked for management, the sound absorbing walls stacked in the conventional sound absorbing wall are supported by the pedestal, and the warpage of the unit sound absorbing walls stacked with the gap is supported by the pedestal So that the soundproof wall can be easily managed.

In other words, in the past, when the unit sound insulation walls are laid down by laying, there is a problem that warpage occurs due to the self-centering of the soundproof walls due to the self-load. Particularly, in a hot summer, such a warpage phenomenon However, the temporary sound barrier wall according to the present invention also serves as a support member for preventing the middle portion of the sound barrier wall from being sagged by the fixing member for fixing the sound absorbing material, thereby effectively preventing the warpage of the unit sound barrier wall. Therefore, it is possible to prevent damage to the product in storage and transportation, and to efficiently manage the product.
