Soundproofing walls using volcanic stones {SOUNDPROOFING WALLS USING VOLCANIC STONES}

The present invention relates to a soundproof wall, and more specifically, to a soundproof wall installed along roads and railroads to block road and railroad noise from being transmitted to a sound collection point.

In general, soundproof walls are structures installed along railroad tracks, roads, etc. to absorb and block friction noise and aerodynamic noise caused by friction between the wheels and rails of railroad vehicles.

However, since conventional soundproof walls must sufficiently withstand wind pressure and impact, high-strength metal is mainly used to maintain strength above a certain level, but this has the problem of making the exterior look clunky and reducing nature friendliness.

In addition, the soundproofing board used in the conventional soundproofing wall as described above uses a method of dissipating the energy of noise generated on the roadside by reflecting sound waves to each other, so it is difficult to expect a sufficient soundproofing effect, and therefore, it is difficult to expect a sufficient soundproofing effect. Absorption methods are being developed.

In this regard, Republic of Korea Patent Publication No. 10-2002-0038153, Republic of Korea Patent Publication No. 10-2019-0079237, etc. disclose a technology for absorbing noise by filling a storage body made of wire mesh, etc. with a porous sound-absorbing material. .

However, these prior technologies used foamed concrete or rubble as sound-absorbing materials, which had problems in that the noise removal effect was minimal or the weight of the soundproof wall became heavy.

In addition, as time passes due to vehicle noise and vibration, the sound-absorbing material filled inside the wire mesh, etc., compacts, creating a space at the top of the soundproof wall, causing a problem that the soundproofing effect is gradually reduced.

The present invention relates to a soundproof wall installed along roads and railways to block road and railway noise from being transmitted to the sound absorption point.

Hereinafter, the soundproof wall of the present invention will be described in more detail with reference to preferred embodiments and the accompanying drawings. In this regard, Figure 1 is a perspective view showing a state in which a soundproofing wall according to the present invention is constructed, Figure 2 is a perspective view showing a state in which H beams are installed on both sides of the soundproofing wall according to the present invention, and Figure 3 is a perspective view showing a state in which a soundproofing wall according to the present invention is installed. It is a perspective view showing an example of a housing filled with a sound-absorbing material in the sound-absorbing wall according to the present invention, and Figure 4 is a perspective view showing another example of a housing filled with a sound-absorbing material in the sound-proofing wall according to the present invention.

Referring to Figures 1 to 4, the soundproof wall 1000 of the present invention may be largely comprised of a support 100 and a soundproof block 200.

The support 100 is a structure that structurally supports the entire soundproof wall with respect to the ground. A plurality of supports are fixed along both sides or one side of the roadway or railway at regular intervals on a foundation structure installed on the ground to have a certain height upward from the ground. Can be installed. In the present invention, an H beam or the like may be applied as the support 100.

The soundproofing block 200 is stacked up and down between the supports 100 to absorb and block sound, and is a major component of the present invention. Here, the soundproofing block 200 may be fixed to the support 100 by a fixing means 300. In the present invention, screws, anchor bolts, etc. may be used as the fixing means 300.

According to one embodiment of the present invention, the soundproofing block 200 includes a block-shaped housing 210 that is formed in a hexahedral shape with a receiving space inside, and whose front side is perforated to form mesh-shaped through holes, and the block. It may be configured to include a sound-absorbing material 220 filled in the receiving space within the type housing 210.

Here, the block-type housing 210 may be formed in a rectangular parallelepiped shape. That is, the housing 210 includes a front plate 212 in which a plurality of through holes 211 are formed, a back plate 213 that is provided at a predetermined distance apart from the front plate and is made of a single sheet, A bottom plate 214 connecting the lower ends of the front plate 212 and the back plate 213 to each other, and a pair of side plates connecting the front plate 212 and the back plate 213 to each other at both side ends ( 215) and a top plate 216 that can be opened and closed at the top of the front plate 212, the back plate 213, and the side plate 215.

In the present invention, the block-type housing 210 is preferably made of aluminum to reduce weight.

In the present invention, porous volcanic stone can be used as the sound absorbing material 220.

The volcanic stone is generally known as pumice or porous basalt, and is a porous stone formed by gathering volcanic glass, minerals, and air bubbles after a volcano erupts. Volcanic stone is porous, lightweight, has a large surface area, and has excellent sound absorption and adsorption effects. In addition, it has a beautiful appearance with a variety of colors such as black and purple and a unique appearance, so it is used in a variety of ways as building materials, filter materials, and garden landscaping stones.

Volcanic stone having the above characteristics is filled in the block-type housing 210 as shown in FIG. 3 and performs the function of absorbing sound generated from roads, etc.

The soundproofing blocks 200 filled with volcanic stones as described above are assembled by stacking a plurality of them and inserting them between supports 100 (H beams) embedded at regular intervals on one or both sides of the road or railway side, as shown in FIG. After that, it is assembled using fixing means 300 such as anchor bolts.

In this way, according to the present invention, since the lightweight porous sound-absorbing material 220 is accommodated and constructed in a standardized block-type housing 210, field constructability is improved.

In addition, in case of breakage/damage, repairs can be made by replacing only the block-type housing 210, which has the advantage of convenient maintenance. In particular, by configuring the upper part of the block-type housing 210 to be openable, there is an effect that the sound-absorbing material 220 can be refilled as needed.

In the present invention, the front plate 212 of the block-type housing 210 can be formed as a perforated plate with a plurality of opening holes so that the sound absorbing material 220 layered inside can absorb the scratches generated from the road, etc. .

More specifically, the front plate 212 may be made of a circular perforated plate with a plurality of circular opening holes, as shown in FIG. 3.

At this time, the size of the opening hole is formed as large as possible for effective sound absorption, but can be selected as an appropriate size so that the volcanic stone filled inside does not leak to the outside.

Additionally, another embodiment of the front plate may be configured to include a mesh network 218 in which wires are woven in a lattice shape, as shown in FIG. 4 .

When the front plate is composed of a perforated plate as shown in FIG. 3, high structural stability can be secured, and when the front plate is composed of a mesh network 218 as shown in FIG. 4, sound absorption efficiency can be improved. Therefore, the configuration of the front panel can be selected and applied depending on the design conditions.

According to the present invention, a front perforated aluminum soundproofing block 200 is used to absorb noise by filling the inside of the soundproofing block 200 with a porous sound-absorbing material 220, such as volcanic stone, thereby reducing the weight of the soundproofing wall, which could not be installed on an existing bridge. This disadvantage can be solved, and the volcanic stone is exposed through the opening hole of the front plate 212 exposed to the roadside, which has the effect of providing a soundproof wall that has an attractive appearance and is environmentally friendly.

On the other hand, when a plurality of soundproofing blocks 200 are stacked in the vertical direction as described above, a gap may occur between the soundproofing blocks 200 and sound may leak through the gap.

Accordingly, according to the present invention, the block-type housing 210 is provided with a packing material (not shown) on the upper or lower surface to seal the gap between the soundproofing blocks 200 and the soundproofing blocks 200 stacked up and down. It can be configured as follows.

At this time, the packing material may be made of elastic rubber or synthetic resin. As a result, the packing material blocks the sound by sealing the gap between the soundproofing blocks 200 and the soundproofing blocks 200, thereby solving the problem described above.

In addition, as in the present invention, in the case of a soundproof wall such as a type that absorbs sound by filling the soundproof block 200 with a sound absorbing material 220, the vibration of the sound caused by the operation of the vehicle, the vibration energy of the sound absorbed by the soundproof wall, etc. As time passes, the sound-absorbing material 220 filled inside the sound-proofing block 200 is compacted, thereby creating a space in the upper part of the sound-proofing block 200. Therefore, as sound passes through the space, a problem may occur in which the soundproofing effect gradually deteriorates over time.

In order to solve this problem, one technical feature of the present invention is to provide various means to ensure that the sound absorbing material 220 filled in the sound insulation block 200 always maintains a constant gap.

In this regard, Figure 5 is a cut-away perspective view showing a state in which the support protrusions and tension wires are installed on the soundproofing block according to the present invention.

Referring to FIG. 5, a plurality of support protrusions 400 may be provided inside the front plate 212 or the rear plate 213 and extend a predetermined length inside the receiving space. As a result, the support protrusions 400 support one side of some of the sound-absorbing materials 220 and prevent the sound-absorbing materials from falling, thereby making it possible to keep the gap between the sound-absorbing materials 220 constant regardless of the passage of time. .

Referring again to FIG. 5, the soundproofing block 200 may be provided with a plurality of tension wires 500 extending between the front plate 212 and the back plate 213 and arranged in a relaxed downward state. there is.

Accordingly, when the gap between the sound-absorbing materials 220 is filled over time despite the installation of the support protrusion 400, the sound-absorbing material 220 is pulled upward by tensioning the tension wire 500 by an external force. By lifting and supporting, it is possible to keep the gap between the sound absorbing materials 220 constant.

Here, one end of the tension wire 500 is fixed and fastened to the front plate 212 or the back plate 213, and the other end is tightened by the fixing unit 510 after tensioning the tension wire 500. It can be mounted on the front plate 212 or the back plate 213. At this time, as the fixing unit 510, a fixing clip or a wedge-shaped anchor can be used if greater tension is required.

According to another embodiment of the present invention, a means for maintaining the gap between the sound absorbing materials 220 can be provided by forcibly injecting air into the soundproofing block 200.

In this regard, Figure 6 is a perspective view of the expansion pocket installed in the soundproofing block, and Figure 7 is a cross-sectional view showing the expansion pocket installed in the soundproofing block.

Referring to Figures 6 and 7, the soundproofing block 200 includes an expansion pocket 610 whose volume expands by air injection, and an expansion pocket 610 that extends from one side and extends to the outside of the back plate 213. It may further include an air inlet 620 that supplies air to the expansion pocket 610.

Here, the expansion pocket 610 communicates between a plurality of unit pockets 610A, 610B, and 610C provided inside the soundproofing block 200 and the unit pockets 610A, 610B, and 610C. It may be configured to include a connection pipe 630 that forms an air flow path.

At this time, the plurality of unit pockets 610A, 610B, and 610C may be alternately arranged left and right and up and down within the accommodation space of the soundproof block 200.

Accordingly, when the sound-absorbing material 220 inside the sound-proofing block 200 is compacted over time, the air gap between the sound-absorbing materials 220 is always kept constant by forcibly injecting air into the expansion pocket 610. You can do it.
