Description

Soundproof Walls {Structure of Noise Barrier}

The present invention relates to a sound insulation wall mainly installed on the road, such as the perimeter of the road boundary, and in particular, the existing uniform sound insulation wall treatment appearance that was treated as a monotonous wall surface of the sound insulation wall installation section can be changed to an environmentally friendly structure, while a special finishing material or auxiliary It can be simply installed without a device, and it is possible to make a simple replacement construction for existing sound insulation and sound insulation walls.

Noise barriers installed between noise areas such as residential areas, roads, and construction sites generally use sound absorbing walls and sound barriers to block noise.

The sound absorbing wall uses a separate sound absorbing material for absorbing noise, and the sound insulating wall is installed along the direction of the noise to block the movement of the noise, and thus does not require a separate sound absorbing material.

The soundproof wall is constructed so that noise hits the soundproof wall and radiates around the noise source, so there is no need to install a separate sound absorbing material. Therefore, it is cheaper than the sound absorbing wall and is easy to install and install according to the surrounding environment of the noise source. .

In general, the sound insulation wall is installed by placing the H-shaped steel on the upper portion of the concrete retaining wall at predetermined intervals and inserting the sound insulation concrete block therebetween.

1 illustrates a conventional sound insulation wall construction structure, in which the construction of the sound insulation wall 10 includes a support frame 40 having bidirectional symmetrical coupling surfaces 30 along with the concrete retaining wall 20 structure, such as an H beam section steel. Standing on the retaining wall 20, along the coupling surface 30 formed on the support frame 40, the panel is fitted with a sound insulating wall 10 on the support frame 40 to the axis.

The sound insulation wall 10 of the sheet used in the construction of the sound insulation wall is panel-shaped in its entire shape and manufactured to have a thickness enough to be easily fitted along the coupling surface 30 of the support frame 40. Along the 40 to install from the bottom to the top.

On the other hand, in order to enhance the sound insulation effect in the construction of the sound insulation wall is also applied to the design to effectively emit the noise emitted from the noise source by forming the surface of the sound insulation wall in the shape of unevenness.

FIG. 2 is a structure in which the surface shape of the sound insulation wall 10 is processed into an uneven shape, thereby intensively refracting the noise radiated from the noise source 50 toward a specific direction rather than feeding back the original path, thereby enhancing the noise shielding effect. For example, if the source of the noise source 50 is a passenger vehicle, if the noise generated from the vehicle is directly fed back to the same position, the noise felt while riding the vehicle becomes too large and does not consider the noise reduction effect on the noise source side. As a result, it may be unsuitable for the road facility, but as shown in FIG. 2, the noise hits the unevenness 60 portion first on the surface of the sound insulation wall 10, and then the front surface of the unevenness 60 so that the refractive direction thereof is directed upward. Given the intended angle of inclination, the noise shielding effect can be provided to the noise source.

As described above, the conventional sound insulation wall has a relatively simple structure in comparison with the sound absorbing wall, and is easy to install, and various sizes and on-site construction conditions are good. Could not get a design. Recently, various sound insulation walls have been proposed to enhance the aesthetics and affinity of the surface, or to diversify the colors to give a visual aesthetic, but the overall shape itself is impossible to be modified, so that the design is improved and monotonous. There was a limit to improving aesthetics.

In addition, a light metal or a non-metallic material having a certain strength is used as a main material of the sound insulation wall, and its shape is exposed as it is.

In order to make up for these drawbacks, some environmentally friendly management has been applied to plant vegetation around the location where the sound insulation walls are installed so that the stems climb up the sound insulation walls to cover the surface of the sound insulation walls.

However, this method also completely compensates for the shortcomings of sound insulation walls classified as non-environmental facilities because they can only be used for a limited time during the season when vegetation growth is active, and because they radiate vegetation on land and can harm urban landscape. It didn't grow in the way it could.

Accordingly, it is an object of the present invention to provide an environmentally friendly sound barrier that can be suitably used as an exposure facility or a building facility on a road.

Another object of the present invention is to provide a sound insulation wall that can be easily and simply constructed around the sound insulation wall support frame.

Still another object of the present invention is to provide a sound insulating wall that can be replaced by replacing the existing support frame.

Still another object of the present invention is to provide a soundproof wall that can be installed without a separate fastener or connecting part during assembly construction by applying a gravity type structure.

A feature of the present invention for achieving the above object, in the sound insulation wall to be fitted along the coupling surface of the support frame having a coupling surface in both directions to assemble the sound insulation wall at a predetermined interval on the concrete retaining wall structure, the sound insulation wall is The upper part is emptied into the vegetation soil space, and the lower part is assembled along the positioned support frame, and the lower part is formed of both ends of the sound insulating wall body and the coupling part formed along the coupling surface of the support frame.

In this way, if the soundproof wall installed around the road is environmentally friendly for noise prevention purposes, it is possible to keep the urban landscape and aesthetics beautiful without the noise shielding effect of the soundproof wall, and construct the soundproof wall as an environmental management facility without any reinvestment. It will be possible to construct a simple, easy to replace the existing construction of the sound insulation wall, and to provide a visually diversified sound insulation wall.

As shown in FIG. 3, the sound insulation wall 70 according to the present invention includes coupling surfaces 72a and 72b that can be assembled to the sound insulation wall 70 at a predetermined interval on the concrete retaining wall 71 structure in both directions. It is designed to fit along the engaging surfaces 72a and 72b of the support frame 73.

Specifically, the sound insulation wall body 75 is assembled along the positioned support frame 73 and the upper part is emptied into the vegetation soil space 74, and the lower part is formed at both ends of the sound insulation wall body 75 and is supported. The coupling portion 76 is coupled along the coupling surfaces 72a and 72b of the frame 73.

In addition, the sound insulation wall main body 75, as shown in Figure 5b, when the direction of the noise source in the front, the front portion is made out of left and right asymmetric triangle shape is not exposed, the front portion is inclined slope 77a Through the triangle can be formed.

Optionally, the engaging portion 76 is composed of a protruding end 78 to be fitted in close contact with the space of the engaging surfaces 72a, 72b of the support frame 73.

Effects of the present invention configured as described above are as follows.

Figure 3 shows the construction state of the sound insulation wall 70 through the sound insulation wall body 75 according to the present invention. Since the sheet sound insulation wall main body 75 according to the present invention has a constant weight, it is gravity-coupled from the top to the bottom along the groove space on the engaging surfaces 72a and 72b of the support frame 73.

For this coupling, the shape of the coupling portion 76 formed on the sound insulation wall body 75 is determined in consideration of the shape of the coupling surfaces 72a and 72b of the support frame 73 in advance.

That is, as shown in FIG. 3, when the engaging surfaces 72a and 72b of the support frame 73 for coupling the sound insulation wall main body 75 are recessed inwardly, the grooves of the support frame 73 may be inserted into and inserted into the grooves of the support frame 73. The coupling portion 76 formed on both side ends of the sound insulation wall body 75 can be easily formed by forming the protruding end 78. In the construction of coupling the sound insulation wall main body 75 to the support frame 73, the assembly is completed by gravity without a separate fastening device or an auxiliary device, and several sound insulation wall main bodies 75 are stacked and stacked in the same order as the former. When raised, the sound insulation wall 70 is completed.
