Description

A soundproof type of a front separation exchange

The present invention relates to a soundproof wall, and in particular, to replace any one of the soundproof plates installed up and down between the struts on the road from the front of the soundproof wall so as to simplify the installation of the soundproof panel as well as easy to maintain the soundproof wall It is about.

In general, noise barriers are installed on roads or railroads where vehicles run so that noise generated from vehicles does not pass to residential areas adjacent to the road.

The soundproof wall is made of a structure that blocks noise by vertically or horizontally coupled with soundproof panels between a plurality of struts installed along a longitudinal direction at an edge of a road or a central separator.

The pillar has a flat cross-sectional shape of 'H' shape, and both ends of the sound insulation board are fitted into and fixed to the vertical grooves formed on both sides thereof.

The sound insulation board mainly consists of a front plate and a back plate, and a sound absorbing material is installed between the front plate and the back plate.

The sound absorbing material is made of a material such as glass wool (polyester), polyester, and the like and absorbs the sound absorbing material from passing through the front plate or the back plate.

Recently, there is an example in which a wood or aluminum foam foam panel is applied, and the wood or aluminum foam foam panel may form an independent sound insulation board without the need for front and rear panels.

The aluminum foam foam panel has a plurality of pores formed therein to absorb the noise flowing through it.

Said sound barriers locate struts along the longitudinal direction of the road at the center or both sides of the road and allow the struts to be fixed to the ground, respectively, via the foundation. Then, the ends of the sound insulation boards are matched between the posts, and then installed in a manner of laminating and pushing them from the top to the bottom one by one from the top to the bottom.

The soundproof panel installed in this way is partially damaged by external shock or aging after a certain time after installation, and the damaged soundproof panel is replaced at this time.In order to replace the soundproof panel during the replacement work, the soundproof panels located on the upper side of the soundproof panel are sequentially separated. There is an inconvenience to replace the soundproof plate after.

Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to install any of the soundproof plates to be separated from the front of the soundproof wall of the soundproof plate is installed stacked up and down between the pillars on the road. And to make it easy to replace.

The present invention to achieve the above object,

In soundproof walls,

A prop that is built and fixed with a plurality of equal intervals along an edge or a median on the road; Sound insulation plates arranged vertically between the support and the support, the coupling brackets are respectively provided to be fixed to the support with fasteners in the state in which both ends of the rear surface is located in front of the support; An elastic finish plate provided on an upper end portion of the rear surface of the soundproof plate and having an upright portion protruding upwardly and an elastic portion bent downwardly from an upper end of the vertical portion; An elastic latching plate protruding downward from the front lower end of the soundproof plate, having an inclined portion having a rear inclination angle, and a seating portion vertically downwardly formed from the inclined portion to elastically close the elastic finishing plate of another soundproofing plate; It includes.

Each flat section of the posts is formed in a "H" shape to form a vertical groove corresponding to each other, and the plurality of fixing brackets are provided so that the coupling brackets are in close contact with the vertical grooves to be coupled to the fastener. Can be applied.

The fixing bracket is made of a flat section of "a" shape or "b" shape or "c" shape or "ㅣ" shape is welded to the inside of the vertical groove, one side is to be fixed to the coupling bracket and fasteners Can be.

In addition, the fixing bracket may be coupled to cover the entire opening of the vertical groove and to be coupled to the fixing bracket by the fastener to the fixing bracket.

As another example, the struts are arranged to form vertical grooves 120 corresponding to each other, each having a flat cross section having an “H” shape, and a connecting bracket protrudes and is provided on the front surface of the strut. Coupling brackets of the soundproof plate may be in close contact and fixed to the fastener.

As another example, the support may have a flat cross section in the shape of a square pipe, and a plurality of fixing holes may be formed so that the coupling brackets of the soundproof plate may be in close contact with both sides thereof, and thus may be coupled with fasteners.

The soundproof plate may include: a rear plate having an open space opened forward and provided with the coupling bracket; Covering the open space and both ends of the extension plate is fixed to the rear plate with a fastener, the upper and lower ends may be made of a front plate having the elastic closing plate and the elastic locking plate.

The front plate may be formed of a plurality of pores or holes formed on the surface, or a concave-convex shape in which protrusions and grooves are continuously repeated in the vertical direction or the left or right direction.

In addition, the sound absorbing material is embedded in the open space, and the sound absorbing material may be applied to materials such as glass wool, aluminum foam foam, and fiber material.

In addition, if there is no open space on the front plate can be applied without the sound absorbing material built-in.

In addition, a locking bracket may be provided such that the rear surface of the soundproofing panel may be in close contact with the front surface of the support in a state where the bottom of the lowermost sound insulation board is locked to the lower end of the support, and between the locking bracket and the ground at the lower side of the support. The cover member may be further coupled to cover the gap of the cover member.

Therefore, the front replaceable soundproof plate according to the present invention has an effect of easily replacing only the damaged soundproof plate when any one of the soundproof plates installed vertically between the posts on the road is damaged.
