The conventional soundproof wall shown in FIG. 1 is a so-called "transparent soundproof wall" 5, which is a road structure 1 fixed to the ground by concrete pouring or the like, and fixed to the road structure 1 and spaced apart from each other. The struts 2 and a soundproof panel 3 interposed between the two struts adjacent to each other.

The sound insulation panel 3 includes a light transmissive sound insulation board 3a and a frame 3b for supporting a circumferential portion of the light transmissive sound insulation board 3a. The light-transmissive sound insulation board 3a is generally made of synthetic resin such as glass or polyethylene, and may be colored with a color such as transparent or green as necessary. In the present specification, the term “transparent soundproof plate” is not limited to colorless and transparent, and colored light may be included as long as light may pass through the soundproof plate itself.

Since the light-transmissive soundproof plate 3a is a plate made of glass or synthetic resin as described above, its overall strength and rigidity is weaker than that of metal, and thus, the support 2 is provided through the frame 3b made of metal. Has been fitted.

Despite the relatively low noise reduction effect by simply shielding, rather than absorbing the noise, the use of a transparent soundproof wall is to solve the frustration of neighboring houses, etc. due to the blocking of light. It has been pointed out that there is a limit in eliminating such frustration because there is a frame 3b which gives a feeling of being trapped by being made of metal without transmitting light at all.

In addition, since the frame 3b is separately manufactured and assembled with the light-transmissive soundproofing plate 3a, there is a problem that the cost and time required for this are largely adversely affected on the installation of the soundproof wall 5.

In order to solve the above problems, an object of the present invention is to provide a soundproof wall to solve the frustration felt by residents of neighboring houses and the like, and improve the aesthetics.

In addition, an object of the present invention is to provide a sound barrier that reduces the cost and time required for installation.

Furthermore, the present invention provides a soundproof wall including a strut having a cross section of various shapes, and in particular, by recycling a strut already installed, a soundproof wall which can reduce the cost and time required for re-installation and achieve the above-mentioned problems. It aims to provide.

In order to achieve the above object, the present invention comprises: at least two struts fixed to stand against the ground and disposed spaced apart from each other; A transmissive soundproof plate disposed over two laterally adjacent struts and disposed in front of the strut; And a gripping member which is fastened to each of the laterally adjacent light-transmissive sound insulating plates, and a gripping member which connects the fastening portions to be in close contact with the front and rear of the strut.

The light-transmissive soundproof plate is coupled to the fastening portion of the gripping member by a fastening assembly, the fastening assembly comprising: a first fastening member disposed behind the fastening portion; A second fastening member interposed between the fastening portion and the transparent soundproof plate; And a third fastening member disposed in front of the light-transmissive soundproof plate, wherein the first fastening member and the second fastening member are fastened to each other by screwing, and the second fastening member and the third fastening member are screwed. It is preferable to be fastened to each other by coupling.

It is preferable that a gap is formed between adjacent light-transmissive sound insulation plates, and the gap is blocked by a gap blocking member. In this case, the gap blocking member includes: a blocking portion for blocking a gap between the transparent sound insulating plates; And fitting parts that are elastically fitted between the light-transmissive soundproofing plates to support the blocking parts. In addition, it is preferable that protrusions are formed at the end of the fitting portion.

It is preferable that a reinforcing member extending in the longitudinal direction of the support and in contact with the inner surface of the support to reinforce the rigidity of the support is arranged, and at least one cross section of the cross section of the reinforcing member is preferred. More preferably, the cross section of the member has a lattice shape.

The sound barrier comprises: a road structure fixed to the ground; Anchors fixed to road structures; A nut fastened to the anchor; And a support plate fixed between the nut and the road structure by tightening the nut, wherein the support is preferably fixed to the support plate by welding.

The cross section of the post may be oval or square, in which case it is preferred that the cap is mounted on the top of the post. The post may be an I beam, in which case it is preferable in that the I beam can be recycled.

Hereinafter, a soundproof wall according to a first embodiment of the present invention will be described with reference to FIGS. 2 to 11. The soundproof wall 100 according to the first embodiment of the present invention includes a support 110, a light-transmissive soundproofing plate 120, and a gripping member 130, and, as necessary, a fastening assembly 140 and a gap blocking member ( 150, and may further include a reinforcing member 160, which will be described in detail below.

The support 110 is fixed to stand against the ground, and the soundproof wall is installed along the length of the road so that two or more support 110 are continuously spaced apart from each other. The strut 110 in this embodiment is not limited to the present invention, if illustrated as a pipe formed of SUS.

As shown in FIG. 4, the strut 110 of the present embodiment is shown to have a circular cross-sectional shape, but the cross-section may be any elliptical shape or a substantially equivalent shape, and in particular, in the present specification, a 'circle' degree ' I will understand it as a kind of ellipse. In this embodiment, the cross-sectional shape of the pillar is elliptical, thereby improving the overall appearance of the soundproof wall to a soft image, which may be particularly advantageous in the emphasis on the urban aesthetics, which has recently been emphasized.

7 shows a fixed structure of the support 110, the support 110 is fixed to the support plate 1c by welding. At this time, the support 110 itself may be directly welded to the support plate 1c, or may be welded through a separate support piece 110a. Of course, both of these may be adopted.

The support plate 1c is tightly pressed to the road structure 1 by tightening the nut 1b on the upper portion of the anchor 1a, thereby being fixed to the road structure 1. The road structure (1) is installed to be fixed to the ground by the concrete pouring, at this time the bottom of the anchor (1a) is hardened in a state buried in the interior of the anchor is firmly fixed to the concrete.

The light-transmissive sound insulation panel 120 is a transparent plate that can be made of, for example, glass or synthetic resin such as polyethylene, which prevents noise generated from the road side from traveling to the other side of the soundproof wall, that is, to an adjacent residential area. It plays a role. For this purpose, the light-transmissive sound insulation board 120 is disposed over two posts adjacent to each other in the lateral direction, and unlike the conventional sound insulation board (soundproof board having a periphery fixed by the frame), the front of the support (X direction: FIG. 4). Is placed on. Although the support 110 in its rear side (opposite in the X direction: FIG. 4) is visible through the transparent sound insulation board 120, the transparent sound insulation board 120 has a smooth surface, rather than the support 110. The visual effect of the light-transmissive soundproofing plate 120 is greater, and thus, the overall aesthetics of the soundproof wall 100 is improved when viewed from the front. This synergizes with the aesthetics that are improved due to the absence of conventional frames, resulting in a remarkable aesthetic effect compared to conventional soundproof walls.

As shown in FIG. 4, the gripping member 130 connects the fastening portions 131 and the fastening portions 131 which are respectively fastened to the laterally adjacent light-transmissive soundproofing panels 120, but the strut 110 is connected thereto. It is provided with a grip portion 132 in close contact with the front and rear with respect to.

In the present invention, the light-transmissive soundproofing plates 120 are coupled to the gripping member 130, and the gripping member 130 is strongly adhered to the support 110 by the coupling thereof, whereby the light-transmissive soundproofing plates 120 are Indirectly fixed to the support (110). The gripping member 130 may be manufactured by bending and bending an elongated metal piece, a part of which is in close contact with the front of the support 110 and the other part of the holding member 130 in close contact with the back of the support. Although the shape of the gripping member is shown to be similar to the 'Ω' shape in this embodiment, other shapes are possible as illustrated in other embodiments described below.

In this embodiment, the fastening part 131 of the gripping member 130 has been illustrated as being coupled to the light-transmissive soundproofing plate 120 by the fastening assembly 140. The fastening assembly 140 includes a first fastening member 141, a second fastening member 142, and a third fastening member 143, which will be described with reference to FIGS. 8 to 10.

First, as shown in FIG. 8, the first fastening member 141 is disposed behind the fastening part 131, and the first fastening member 141 and the second fastening member are disposed with the fastening part 131 interposed therebetween. Screw (142) (the fastening portion 131 is a male screw of the first fastening member (in this embodiment, it is illustrated that the male screw is formed on the first fastening member and the female screw is formed on the second fastening member, which will be reversed) Can be penetrated in advance).

Then, by using the elasticity of the holding member 130 to open the fastening portion 131 to fit the holding member 130 to the support 110, the holding portion 132 is coupled to the support 110 is shown in FIG. It is shown. In this state, the light-transmissive soundproofing plate 120 is positioned (aligns the hole of the light-transmissive soundproofing plate with the female screw hole of the second fastening member), and the second fastening member 142 is provided with the light-transmissive soundproofing plate 120 interposed therebetween. Screw the third fastening member 143 (see FIG. 10) (the screw of the third fastening member is formed on the periphery of the soundproof plate (in this embodiment, a male thread is formed on the third fastening member and a female thread is formed on the second fastening member). But this can be reversed) and holes are formed in advance). As a result, the second fastening member 142 is interposed between the fastening part 131 and the light transmissive sound insulation plate 120, and the third fastening member 143 is disposed in front of the light transmissive sound insulation plate 120.

As described above, in the present invention, the light-transmissive soundproof plate 120 is fixed to the support 110 by screwing the gripping member 130 and the fastening assembly 140 having a simple structure, so that the cost of installing the soundproof wall And time is saved.

In addition, the light-transmissive soundproof panel 120 fixed as described above is detachable by loosening only the third fastening member 143. This detachability is such that the breakage of the light-transmissive soundproof panel (when the vehicle runs on the road, stones are stepped on the corners of the tires). Stones often bounce towards the sound barrier), which is advantageous when replacing only broken sound insulation panels. That is, in the conventional case, when the sound insulation panel disposed on the lower side is damaged, all the sound insulation panels disposed on the upper side should be lifted to replace the sound insulation panel, but in the present invention, when only the third fastening member 143 is loosened, the sound insulation panel It is easy to replace because it can be separated forward (X direction).

The transparent sound insulating plates 120 may expand and contract according to temperature, and the transparent sound insulating plates 120 may be disposed to be spaced apart from each other in the Y direction and the Z direction. In this case, since noise may leak into the gap between the transparent sound insulating plates 120, the gap may be deformed without damage due to the expansion and contraction, but the gap blocking member 150 may be firmly supported by the transparent sound insulating plate. It is desirable to be blocked. However, the gap blocking member 150 is not necessarily required for the above-described aesthetics, and when added, the noise blocking effect is improved.

As shown in FIG. 5, the gap blocking member 150 includes a portion 151 that partially overlaps the transparent sound insulating plate 120 to prevent leakage of noise between the transparent sound insulating plates 120. And a fitting portion 152 that is fitted between the light-transmissive soundproofing plates to support the blocking portion 151. The fitting portion is elastically deformable so that the fitting portion is inserted into the gap while collecting the end portion 152a. After the fitting portion, the fitting portions 152 are spread to both sides, so that the heat-shrinkable light transmissive plates 120 are contracted. It will not fall out. In particular, for example, hook-shaped protrusions are formed on both outer sides of the end portion 152a to be reliably prevented from being separated from the light-transmissive soundproofing plate 120 by the heat shrinkage.

On the other hand, the support 120 should be configured to be able to hold firmly against the wind load (force of the wind) to the front or rear that can be applied to the soundproof wall 100, conventionally this is simply the support (formerly I beam) It was common to design large thickness and external dimension. In this case, however, the cost of the material increases.

In the present invention, in order to solve these disadvantages, the configuration adopting the reinforcing member 160 in the support 120 is adopted. The reinforcing member 160 extends in the longitudinal direction (Z direction) of the support in the interior of the support 100 and contacts the inner surface of the support to reinforce the rigidity of the support. 4 and 6 illustrate a reinforcing member 160 having one cross section 161 in a cross section, but the present invention is not limited thereto, and two or more cross sections may be provided. When the number of intersections increases, the reinforcing member 160 may have a lattice-shaped cross section. As a modification, the reinforcing member 160 may have a honeycomb-shaped cross section.

Of course, the cost is increased for the fabrication of the reinforcing member 160 itself, but under the premise that the resistance of the strut 110 against wind load is designed to be the same, to adopt the reinforcing member 160 and to make the thickness of the strut 120 thinner. It is advantageous to reduce the overall cost. Meanwhile, although FIGS. 8 to 10 illustrate that the holding member 130 is coupled to the support 110 in a state where the reinforcing member 160 is fitted in the support 120, the reinforcing member 160 may include the holding member 130. After being coupled to the support 110, it may be fitted within the support 110.

On the other hand, since the cross section of the support 110 is sealed, water may be filled in the support 110 by rain or the like. This is not only hygienic, but may also adversely affect the durability of the soundproof wall 100, so it is preferable to prevent water from filling in the support, as shown in FIG. 11, the cap 170 at the upper end of the support 110. Is preferably mounted.

Hereinafter, referring to FIG. 12, the soundproof wall according to the second embodiment will be described based on differences from the first embodiment. In the second embodiment, the cross section of the support 210 is a rectangle (including a rectangle and a rectangle), and sides of the rectangle are inclined with respect to the light-transmissive soundproofing plate 120, so that the light-transmissive soundproofing plate 120 is referred to. It is different from the first embodiment in that it is a rhombus shape.

Due to the difference as described above, the shape of the gripping member 230 is also different, as shown in FIG. 12, but the gripping member 230 basically has the fastening part 231 and the gripping part 232. The points are the same as in the first embodiment, and their respective functions are also the same as the corresponding parts in the first embodiment. On the other hand, it is preferable that the reinforcing member 260 is also inserted in the support 210, as in the first embodiment, wherein the end 261 of the reinforcing member 260 is the edge 211 of the support 210 It is preferable to prevent the displacement from being fitted correspondingly.

In addition, matters not described separately may be easily derived from matters of the second embodiment that are the same as or different from the first embodiment.

Hereinafter, referring to FIG. 13, the soundproof wall according to the third embodiment will be described based on differences from the second embodiment. The third embodiment is the same as the second embodiment in that the cross section of the support 310 is rectangular, but the sides of the rectangle are disposed parallel or perpendicular to the transparent soundproof panel 120, so that the transparent soundproof panel 120 is provided. Also in view of the reference point is a square is different from the second embodiment.

The shape of the gripping member 330 is also changed due to the above difference, but the specific shape thereof is as shown in FIG. 13, but the gripping member 330 basically has the fastening part 331 and the gripping part 332. The points are the same as in the second embodiment, and their respective functions are also the same as the corresponding parts of the second embodiment. Between the fastening part 331 and the gripping part 332 of the gripping member there is an intermediate portion 333 bent in a '-' shape, the gripping member 330 is in close contact with the front of the support 310 It is part to be.

On the other hand, it is preferable that the reinforcing member 360 is also inserted in the support 310, in which the end portion 361 of the reinforcing member 360 is fitted to correspond to the edge 311 of the support 310 It is the same as the second embodiment in terms of prevention of deformation.

In addition, matters not described separately may be easily derived from matters of the third embodiment that are the same as or different from the corresponding matters of the second embodiment.

Hereinafter, referring to FIG. 14, the soundproof wall according to the fourth embodiment will be described based on differences from the third embodiment. The fourth embodiment differs from the above-described embodiments in that it adopts the I beam, which has been used in the past, as the support 410. Due to this difference, it is generally the case that the reinforcing member and the cap are not used in this embodiment.

This embodiment has a particularly advantageous configuration when replacing the soundproof wall which is already installed with the soundproof wall according to the present invention, since the I beam has generally been used as a post. That is, the present embodiment is configured to exhibit the advantages (specifically, aesthetics improvement) of the present invention described above by recycling the posts 410 that are already installed without removing them.

On the other hand, the gripping member 430 in this embodiment is similar to the gripping member 330 in the third embodiment as a whole, but the intermediate portion 433 between the fastening portion 431 and the gripping portion 432 is curved. This is different from the third embodiment, which is to facilitate the operation when the holding member 430 is coupled to the support 410 by opening the fastening portion 431 of the holding member, and the middle of the third embodiment. Of course, the portion 333 can also be formed in this way.

In addition, the matters not described separately may be easily derived from the matters of the fourth embodiment which are the same as or different from the corresponding matters of the third embodiment.

According to the present invention, there is provided a soundproof wall that eliminates the frustration felt by residents such as neighboring houses and improves aesthetics. In addition, according to the present invention, there is provided a sound barrier that reduces the cost and time required for installation.
