Description

Temporary Soundproof Walls {TEMPORARY SOUNDPROOFING WALL}

The present invention relates to a temporary soundproof wall, and more particularly, in the construction of a temporary soundproof wall constructed in a construction site or the like, by improving the degree of freedom of connection between unit soundproof walls, while improving the work flexibility and work efficiency, while preventing the noise of the temporary soundproof wall And to improve the structure of the temporary soundproofing walls, such as to improve the recyclability.

In general, building construction sites such as apartments, buildings, factories, and waste treatment sites are divided into construction sites to block public access to prevent safety accidents caused by falling objects or falls, and to prevent internal accidents. Temporary soundproof walls are constructed in the form of fences in order to block construction noise and to minimize dust scattering.

As the industry develops and the life becomes more abundant, the issue of ensuring the convenience and comfort of human life is now emerging as one of the important development policies by reducing various environmental pollution. As such, while limiting and reducing many pollution factors for a comfortable life, pollution and dust (dust) pollution are the most exposed to modern people and must be reduced for a pleasant life.

The places where such noise and dust are generated are various construction sites for new construction or reconstruction of buildings. In this construction site, various noises such as various mechanical noises are generated during construction, and this construction noise causes serious noise pollution in houses, offices, or schools located around the site. In particular, when the construction site is located along the road, the construction noise is combined with the vehicle noise, which causes tremendous stress on the people.

Accordingly, the construction site of apartments and new buildings, etc., blocks noise and dust generated at the construction site and installs so-called temporary soundproof walls in the form of fences during construction for the safety of pedestrians. Remove the temporary soundproof walls.

The temporary soundproof walls have various materials and shapes such as steel, RPP, EGI, AL, etc. In particular, the sound absorbing material is embedded between the front panel and the rear panel, which form the soundproof panel, which is a unit element of the soundproof wall, and the assembly is completed by combining them. Temporary sound barriers having a structure are mainly used.

In connection with this, the Republic of Korea Patent No. 10-1730976, Republic of Korea Patent No. 10-0945461, Republic of Korea Patent No. 10-0930498, Republic of Korea Patent No. 10-0900344, Republic of Korea Patent No. 10-0536826 It is starting.

However, in the existing temporary soundproof walls, there is a structural limitation that the unit soundproof walls have a lot of restrictions in assembling and construction in constructing a soundproof wall that surrounds the construction site in the form of a fence by interconnecting the unit soundproof walls. When installing and removing the sound barrier, there was a problem in that the flexibility and efficiency of the work was lowered.

In other words, the existing temporary soundproof walls have an assembly structure in which the unit soundproof walls are normally assembled by male and female structures, but do not flexibly cope with the angular change but are connected in a straight line. The construction of temporary soundproofing walls is not possible in a desirable situation, it is unnaturally forced, or it is simply set up with a gap between unit soundproofing walls. This structure is difficult to achieve, there is a problem that the work efficiency is low and the flexibility of the work is lowered, such as the degree of freedom of connection in the construction of the temporary soundproof wall and the long time to build or dismantle process.

In addition, the existing temporary soundproof walls are made of sound absorbing material filled in the space between inner and outer boards and locally exposed through the through-holes of the inner board, and the contact area between the sound absorbing material and the noise is relatively small and the sound absorption efficiency is compared with the area of the sound absorbing material. This is extremely poor, 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 by continuous diffuse reflection in the space cannot be obtained. In addition, the noise reduction efficiency of the soundproof wall was low, and thus there was a problem inferior product quality.

In addition, the sound absorbing material embedded in the soundproof wall space is usually fixed by using an adhesive, and after dismantling the soundproof wall, it is necessary to separate the heterogeneous sound absorbing material in the space when recycling. It is following.

On the other hand, the existing temporary sound insulation wall, it can be laid down during management and transport to maintain a stacked state, a pedestal (not shown) is provided on the outer sides of both sides of the unit sound insulation wall so that a predetermined gap (gap) is usually formed between the stacked unit sound insulation wall Installed on each floor, the existing temporary sound-proof walls had a problem that the warpage occurs because the center portion is struck due to its own load, especially in the hot summer, such warpage (warpage) has a problem that is intensified.

The present invention devised an optimally designed temporary soundproofing plate in view of the above-mentioned problems of the prior art, and in constructing a temporary soundproofing wall covering the construction site in the form of a fence, the degree of freedom of connection between unit soundproofing walls is high, so assembling and construction are easy. By being able to be performed, the purpose is to improve the work flexibility and work efficiency when constructing a temporary soundproof wall.

On the other hand, an object of the present invention is to provide a temporary sound-proofing wall to facilitate the separation operation of the sound absorbing material during disassembly of the soundproof wall, thereby improving the recycling of resources.

On the other hand, an object of the present invention is to provide a temporary sound insulation wall that can be effectively prevented warpage phenomenon that the center portion of the surface of the unit sound insulation wall laminated with a gap is supported by the pedestal is struck by its own weight.

In order to achieve the above object, the present invention, the unit soundproof wall is connected to each other around the construction site construction, as a temporary soundproof wall for shielding the noise and dust from leaving the construction site;

The unit soundproof wall is:

A front panel exposed to the outside of the construction site, a rear panel which is spaced apart from the front panel by a predetermined distance and a plurality of holes are formed on the surface, an intermediate panel located between the front panel and the rear panel, and the rear panel It is configured to include a sound absorbing material provided between the panel and the middle panel,

Between the unit soundproof wall connected to the neighbor, characterized in that the unit is further provided for connecting the unit soundproof wall to each other at a predetermined angle.

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

First, in the provisional soundproof wall according to the present invention, in constructing a soundproof wall that surrounds the construction site by forming a fence by interconnecting the unit soundproof walls, the degree of freedom of connection between the unit soundproof walls is high, so as to increase work flexibility and work efficiency in assembly and construction. do.

In addition, unlike the existing temporary soundproof walls, the unit soundproof walls can be connected in various ways, and the connection angles of the assembly sites can be smoothly adjusted according to the environment of the construction site. Soundproof wall construction is effective.

In addition, the temporary soundproof wall according to the present invention is a sound absorbing material which is a sound absorbing material embedded in the internal space of the unit soundproof wall is a physically fixed by the pressure of the fixing member, not by a chemical bonding method using an adhesive, Separation of the work is easy to be made, thus improving the recyclability has many effects.
