BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound absorbing device for remodeling a sound barrier wall, and more particularly, to a sound absorbing device for remodeling a sound barrier wall which can be mounted on a conventional sound barrier wall,

Generally, soundproof walls are installed around various facilities such as highways, railways, subways, ports, and schools.

These soundproof walls are installed on the edge along the roads and are designed to shield the noise generated in the vehicle from spreading to the surrounding area.

Especially, in the densely populated areas and on the roads near schools and government offices, measures are taken such as soundproof walls to reduce the noise caused by vehicle traffic and to maintain a pleasant environment.

Generally, a soundproof wall is installed in a structure in which a post such as an H-beam or the like is formed on a foundation concrete, and then a soundproof panel including a sound absorbing plate, a front plate, and the like is sandwiched from above to below between the posts.

However, the soundproof wall of the prior art has a disadvantage in that the design of the soundproofing structure is simple and the aesthetic appearance of the building is degraded and the noise reduction function is insufficient and the durability is short due to the corrosion caused by the spraying of calcium chloride in the winter season. In case of replacement due to breakage, There is a disadvantage in that an economic loss is large, for example, the entire plate needs to be replaced.

In addition, since the sound-absorbing plate and the front plate have to be pulled out or inserted one by one when the sound-absorbing wall is replaced, the workability is very inconvenient and the operation time is long.

When the soundproof wall is remodeled, the old soundproof panel (sound absorption plate + front plate) is removed and a new sound insulation panel is installed. In this case, disposal of the existing sound insulation panel causes environmental damage, There is a problem that the economic loss is increased due to the increase in the construction cost due to the replacement.

Various prior arts have been disclosed for remodeling a sound barrier to overcome such a problem.

Korean Patent Application No. 2008-0074202 discloses a remodeling structure for a soundproof wall, and domestic patent application No. 2010-0068142 discloses a device for remodeling a wing-shaped soundproof wall and a method for remodeling a soundproof wall using the same.

However, the conventional art has a problem in that the structure is complicated, soundproofing and sound absorption performance are deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a soundproof wall which can remodel an old soundproof wall without removing the old soundproof wall to improve the performance of a soundproof wall, And it is an object of the present invention to provide a sound absorbing device for remodeling a soundproof wall capable of improving soundproofing and sound absorbing performance.

It is an object of the present invention to provide an H-beam and an H-beam, which are mounted on a soundproof wall made up of a plurality of H beams vertically mounted on the ground and a plurality of sound insulation boards joined together between the plurality of H beams, A clip bar horizontally attached between the front and rear ends of the clip bar; And a design plate including a front plate having a pattern formed thereon and a sidewall formed by bending an edge of the front plate and the sidewall being coupled to a fitting portion of the clip bar.

And a mounting member attached to the H beam and having a clip bar attached to the front surface thereof.

Wherein the mounting member is one selected from a steel plate welded to the H beam or a flange clip coupled to the H beam.

According to the present invention, by applying an aluminum material, it is excellent in resistance to corrosion, flame resistance, and fire retardancy. By applying the micro-perforation technique, the metal material design plate can exhibit the sound absorption function. By applying the design suitable for the road and residential environment, It is possible to reduce maintenance budget of soundproof wall by installing existing soundproof walls on front and back without disassembly by design plate and fixed frame structure which is improved and easy to install and maintain.

In addition, reduction of waste disposal volume can reduce waste disposal cost and reduce carbon dioxide generation, which can greatly contribute to environmental improvement.

FIG. 12 is a partially enlarged perspective view showing a combined state of the clip bar and the design plate.

1 to 12, a sound absorbing apparatus for remodeling a sound barrier wall according to a first embodiment of the present invention includes a plurality of H beams 100 mounted perpendicularly to the ground, and a plurality of H beams 100 And a plurality of sound insulation boards 200 formed of a plurality of sound insulation boards 200 which are coupled between the clip bars 2 and the design board 4 A mounting member is included to facilitate mounting the clip bar 2 to the H beam 100.

In an embodiment of the mounting member, the clip bar 2 is preferably a steel plate 5 welded to the side flange of the H beam 100, which will be described later.

The attachment method of the clip bar (2) is by piece fitting or welding.

The clip bar 2 is attached horizontally between the H beam 100 and the H beam 100 and has a fitting part 20 formed on the front face and a piece P is formed on both sides of the fitting part 20 And a wing portion 25 is formed by folding both sides of the long side of the metal plate and then folding upward to form a fitting portion 20 The fitting portion 20 and the wing portion 25 on both sides are formed symmetrically.

The fitting part 20 is formed by the first and second bodies 21 and 22 with the fitting piece 23 formed at the upper end thereof and the first and second bodies 21 and 22 The side wall 44 of the design plate 4 can be fitted and engaged with a slot between each of the fitting pieces 23 and the fitting piece 23 of the design plate 4. [

6, the upper end of the first body 21 or the second body 22 is bent in an oblique line so as to have a Λ shape, and the first body 21, The fitting pieces 23 of the first and second bodies 22 and 22 are brought into contact with each other so that the side wall 44 of the design plate 4 is fitted and then a clamping force capable of being strongly fixed by the elastic force is exerted.

Alternatively, as shown in Fig. 7, an arc-shaped bent portion 232 is formed on the upper end of the first or second body 21 or 22, And a bent portion 233 which is inclined at the end portion of the curved portion 232 and widened outward may be formed.

Since the embossing 46 is formed on the side wall 44 of the design plate 4 so as to be described later, the embossing 46 can be inserted into the curved portion 232 and can be engaged with the folded portion 233, A strong clamping force can be exerted while being in close contact with each other, thereby firmly holding the side wall 44 of the design plate 4.

2 to 5D, the design plate 4 includes a front plate 42 having a square shape and a rectangular shape, a side wall 44 formed by bending the edges of the front plate 42 at right angles, And the sidewall 44 is engaged with the fitting portion 20 of the clip bar 2.
