BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a soundproof wall installed on a side of a road and on a side of a bridge to block noise generated in a road, and a rotary soundproof panel unit used therefor. More specifically, the present invention relates to an outer frame and a soundproof panel rotatably installed therein The soundproof panel has a structure in which the soundproof panel rotates to easily communicate the wind when the wind is blowing. In particular, the soundproof panel has a spherical (ball type) It is filled with a state capable of floating and has a through hole through which wind can pass in the thickness direction so that it can freely pass the wind in the lateral direction of the road and the bridge, "Rotating Soundproof Panels with Wind Load Reducing Structure with Built-in Sound Absorbing Materials Units and to a sound barrier, "using the same.

Soundproofing walls are most commonly used to counteract noise around roads by blocking noise sources using shields. Soundproofing walls are basic components of a soundproof panel (or rotary soundproof panel unit) that reflects or absorbs noise, a support for fixing and supporting it, and a foundation for installing the support, Respectively.

Soundproof walls have a vertical wall shape, which is dominated by wind-induced wind loads. In recent years, however, as the shape of residential areas adjacent to roads has become higher and higher density, the height of the sound barrier installed to cope with complaints caused by road noises has also been increased. There is an exponential increase in the sectional force due to the wind load that determines the size of the piers, the anchors and the foundation of the soundproof walls (the concrete barrier walls in the case of bridges). In order to solve such a problem, it is necessary to provide a structure capable of reducing the wind load by naturally inducing and discharging the air colliding with the sound barrier wall, and at the same time ensuring sufficient soundproofing performance. Korean Patent No. 10-0886467 discloses various types of soundproof walls for reducing wind load and soundproof panels used therein. However, such conventional techniques have a limitation in that sufficient wind load reduction effect and soundproof effect can not be expected.

In the rotary soundproof panel unit of the present invention shown in Figs. 1 and 2, the rotation axis R exists on both sides in the width direction (longitudinal direction) of the soundproof panel 100, and the outer frame 101 and the soundproof panel 100 And the transverse side surface is rotatably engaged by the rotation axis R. Therefore, the first sound communication is performed while the soundproof panel 100 rotates around the rotation axis R by the force due to the wind.

The soundproof wall 200 according to the present invention may be constructed using a rotary soundproof panel unit as shown in FIG. 3 or may be constructed with only the soundproof panel 100 without the outer frame 101 as shown in FIG. 4 . 3, a plurality of pillars 202 are vertically installed and fixed to the base structure 201 at intervals in the longitudinal direction. The pillars 202 are disposed between adjacent pillars 202 The sound insulation wall 200 is formed by the rotary sound insulation panel unit of the present invention. In the case of installing the rotary sound-proof panel unit, a plurality of rotary sound-proof panel units can be stacked vertically in accordance with the height required for the sound barrier 200, as in the case of the embodiment shown in FIG. 3, And the longitudinally opposite ends of the rotary sound-proof panel unit are vertically fitted in a space formed by the upper and lower flanges of the H-shaped steel and the web, so that the rotary sound-proof panel unit can be installed between the supports 202.

However, as shown in FIG. 4, the soundproof wall 200 of the present invention can be constructed by only the soundproof panel 100 without the outer frame 101. FIG. 4, a plurality of pillars 202 are vertically installed and fixed to the base structure 201 with a space therebetween in the longitudinal direction. In the space between the pillars 202 adjacent to each other, The sound insulation wall 200 can be formed by a structure in which the rotary shaft R is directly disposed and the longitudinal axis R of the sound insulation panel 100 is between the side wall and the column 202. [ The rotary shaft R may be provided in the end plate 17 at both ends of the longitudinal direction of the soundproof panel 100 as in the following embodiments. However, only the hole is formed in the end plate 17, The soundproof panel 100 may be rotatably fitted to the rotary shaft insertion hole formed in the end plate 17 in a state where the rotary shaft R is coupled to the rotary shaft 202.

In the following, the structure of the soundproof panel 100 itself, which is rotatable by the wind, but which also makes the sound pass through the wind itself, will be described.

5 is a schematic perspective view of a soundproof panel 100 according to an embodiment of the present invention. FIG. 6 is a schematic exploded perspective view of the soundproof panel 100 shown in FIG. 5, A schematic cross-sectional perspective view along the line AA in Fig. 5 is shown.

A soundproof panel 100 according to the present invention includes a main body 1 having an empty internal space and a plurality of sound absorbing materials 2 which are formed in a spherical shape and are contained in the main body 1, . A wind guide member 3 for guiding wind to the through hole 11 formed in the main body 1 may be further provided.

Specifically, the main body 1 is a member having an upper surface, a lower surface, an end surface, a front surface and a rear surface, and an empty space formed therein. 5 and 6, the upper surface plate 15 and the lower surface plate 16 extending in the longitudinal direction are disposed side by side to form the upper surface and the lower surface of the main body 1, respectively, and the upper surface plate And the end plate 17 is coupled to both longitudinal ends of the bottom plate 16 to form an end face.

Each end plate 17 may be provided with a rotation axis R as shown in the figure. It is preferable that the position of the rotation axis R is located above the center of the height of the main body 1 in the vertical direction. When the rotary shaft R is positioned higher than the center of the height of the rotary shaft R, the lower portion of the upper portion of the soundproof panel 100 relative to the rotary shaft R is larger than the upper portion of the rotary shaft R, Therefore, when the wind blows, the soundproof panel 100 does not rotate 360 degrees, but stably rotates within a range of 180 degrees to communicate the wind.

Although the rotary shaft R is shown and described in the soundproof panel 100 in the embodiment shown in the drawings, the rotary shaft R may be disposed between the soundproof panel 100 and the outer frame 101, (100) and the support (202), and it is not necessarily required to be provided in the soundproof panel (100). The rotary shaft R is provided in the support 202 or the outer frame 101 and the rotary shaft insertion hole is formed in the end plate 17 of the soundproof panel 100, And may be fitted to the plate 17.

In the embodiment shown in Figs. 5 and 6, a plurality of side surface forming plate members 19 extending in the longitudinal direction are arranged side by side at intervals to form the front surface and the back surface of the main body 1, respectively. The through holes 11 are formed in the front surface and the back surface of the main body 1 by the spacing between the side surface forming plate members 14 because the side surface forming plate members 19 are disposed with an interval. That is, the front and back surfaces of the main body 1 formed by the side surface forming plate member 19 are formed with through holes 11 through which the wind can flow through the thickness of the main body 1, respectively.

In the embodiment shown in Figs. 5 to 7, the side surface forming plate member 19 is elongated in the longitudinal direction so that the through hole 11 is also formed to extend in the longitudinal direction. However, In the soundproof panel 100, the side surface forming plate members 19 extend in the vertical direction, and a plurality of the side surface forming plate members 19 are spaced apart from each other in the longitudinal direction to form the front surface and the back surface. Fig. 8 is a schematic perspective view corresponding to Fig. 5 for another embodiment of a soundproof panel 100 according to the present invention. In the case where the side surface forming plate members 19 extending in the vertical direction are arranged at intervals in the longitudinal direction to form the front surface and the back surface of the main body 1, the through holes 11 are also formed long in the vertical direction.

As described above, in the soundproof panel 100 of the present invention, when the through-hole 11 is formed, the through-hole 11 is formed at a position opposite to the front surface and the back surface of the soundproof panel 100 in the transverse direction desirable. The sound absorbing material 2 may be in the form of a ball shape and the sound absorbing material 2 may be formed in the body 1 of the soundproof panel 100 A sound absorbing material leakage preventing net 110 may be installed in the through hole 11 in order to prevent foreign matter from flowing into the soundproof panel 100. [ have. The size of the through hole 11 is made smaller than the size of the sound absorbing material 2 in place of the provision of the net 110 in the through hole 11 or in place of the provision of the net 110, So that it does not escape out of the main body 1.

In the present invention, either or both of the front surface and the back surface of the main body 1 may be provided with a wind guiding member 3 for guiding wind blowing to the through hole 11, respectively. 5 to 8, wind guiding members 3 are attached to the outer surfaces of the side surface forming plate members 19 forming the front surface and the back surface of the main body 1, respectively. In particular, the wind inducing member 3 may have a triangular shape such that its protruding shape protrudes from the vertex of the triangle when viewed from the longitudinal cross section. As shown in the drawing, the through-holes 11 are elongated in the longitudinal direction or the vertical direction according to the longitudinal arrangement or vertical arrangement of the side-surface plate members 19, and the through- It is preferable that the wind guide member 3 is also made of a member elongated in the longitudinal direction or the vertical direction.

When the wind guide member 3 is provided as described below, the wind blowing toward the front or back surface of the soundproof panel 100 hits the wind guide member 3 and is divided by the wind guide member 3, Through the through hole (11). Therefore, when the wind guide member 3 is provided, the wind can be guided to the through hole 11 and flow smoothly, which is a great help to reduce the wind load applied to the front and rear surfaces of the soundproof panel 100.

Although the wind guide member 3 and the side plate member 19 are described as being assembled with each other in the above description, when the side plate member 19 is manufactured, the wind guide member 3 is made to exist from the beginning It is possible. That is, the side surface defining plate member 19 and the wind guide member 3 may be integrated from the beginning.

On the other hand, in the above description, the upper panel 15 and the lower panel 16 constituting the soundproof panel 100, the end panel 17 and the side surface plate member 19 are separated from each other The soundproof panel 100 of the present invention has a structure in which the upper surface plate 15, the lower surface plate 16 and the end plate 17 are integrally formed and the front surface and the rear surface are also composed of the front plate 12 and the back plate, As shown in FIG. 9 and 10 show a soundproof panel 100 according to another embodiment of the present invention having a main body 1 having a box-like shape in which a top plate, a bottom plate, an end plate, a front plate, A schematic perspective view (FIG. 9) and a schematic exploded perspective view (FIG. 10) are shown. 9 and 10, the front plate 12 and the back plate 11, which are cut out from the front plate and the back plate, respectively, are formed in the body 1, and the wind guide member 3 are disposed at the intervals between the through holes 11 and are integrally attached to the front plate 12 and the back plate.

In the soundproof panel (100) of the present invention, a plurality of sound absorbing materials (2) are contained in the empty interior of the main body (1). The sound absorbing material (2) is made of a lightweight material that has a void in its interior to exhibit sound absorption performance, and can be floated to the air by wind pressure when the wind blows. For example, the sound absorbing material 2 can be made of a material such as glass wool, rock wool or polyester.

11 and 12 show schematic cross-sectional views along the line AA in Fig. 5, wherein Fig. 11 shows the state when the wind is blowing weakly and Fig. 12 shows the state when the strong wind blows will be. In Figs. 11 and 12, the arrow indicates that the wind is flowing.

In the embodiment shown in Figs. 11 and 12, the shape of the sound absorbing material 2 is shown as being made of a perfect spherical shape. The sound absorbing material 2 need not be a perfectly spherical shape, And may have a spherical shape having a cross-sectional shape.

When the sound absorbing material 2 is contained in the main body 1, the inside of the main body 1 may be filled with a single space so that a plurality of the sound absorbing materials 2 are stacked in one space. However, The inner space of the main body 1 is divided into a plurality of layers in the vertical direction so as to sufficiently secure the floating space in which the sound absorbing material 2 can easily float due to the wind pressure generated as it passes through, It is more preferable that the sound absorbing material 2 is contained. That is, as shown in the figure, a horizontal interlayer dividing member 31 is provided in the internal space of the main body 1, so that the internal space of the main body 1 is divided into a plurality of layers in the vertical direction, It is preferable that a plurality of sound absorbing materials 2 are contained in each layer. According to such a configuration, a sufficient space can be secured above the sound-absorbing material 2, so that when wind pressure is generated in the main body 1 while the wind passes, the sound-absorbing material 2 floats smoothly, . It is preferable to use a net-shaped member for allowing the wind to smoothly communicate with the interlayer partitioning member 31. [

The operation of the soundproof panel 100 according to the present invention will now be described with reference to the drawings. The wind blowing toward the front surface or the back surface of the soundproof panel 100 rotates the soundproof panel 100 itself about the rotation axis R and flows into the inside of the main body 1 through the through hole 11 do. However, when the intensity of the blowing wind is low, sufficient wind does not flow into the main body 1, and the wind pressure inside the main body 1 formed by the wind becomes small. Therefore, as shown in FIG. 11, 2 are held in the main body 1 in a state in which the sound absorbing members 2 are in close contact with each other without floating. In this way, in the main body 1, the path through which the noise can pass is blocked by the stacking of the sound absorbing material 2 in close contact with each other. Thus, the noise is mainly caused by the lateral It is reflected by the sound absorbing material 2 and is absorbed by the sound absorbing material 2 even if it flows into the through hole 11 together with the wind. Therefore, noise is prevented from passing through the soundproof panel 100 of the present invention, and a very excellent sound insulation effect is exhibited.

A large wind pressure is applied to the sound absorbing material 2 inside the main body 1 while a large amount of wind is introduced into the main body 1 through the through hole 11 on one side. The sound absorbing material 2 is made of a lightweight material so that when the large wind pressure acts, the sound absorbing material 2 floats up in the main body 1 by the wind as shown in FIG. 12, So that the wind passes through the sound absorbing members 2 and flows through the through holes 11 on the other side. That is, the wind flows through the main body 1. Therefore, the wind load directly applied to the front surface or the back surface of the soundproof panel 100 is greatly reduced. However, the noise introduced into the interior of the main body 1 along with the wind is absorbed and reflected by the sound-absorbing material 2 while striking the sound-absorbing material 2, so that excellent sound-blocking performance is still exerted.

In the present invention, the main body 1 may be made of a transparent member. The front plate 12 or the side surface forming plate member 19 of the main body 1 to be viewed by at least a vehicle passing through the road can be made of a transparent member even if not all of the main body 1, The plate and wind guide member 13 can also be made of a transparent member. In this case, if the sound-absorbing material 2 is made to have various kinds of hues, the sound-absorbing material 2 floats due to the wind and images of moving various colors are produced, thereby providing a visual pleasure to the vehicle traveling on the road The effect can be achieved. That is, according to the present invention, various colors are appropriately given to the sound absorbing material 2 as needed, thereby providing a visual pleasure to the road rider and preventing the road rider from feeling bored, thereby preventing drowsiness driving, It is possible to achieve the effect of being able to plan. This ornamental effect is exerted very largely when the sound absorbing material 2 is spherical.

The soundproof panel 100 rotates about the rotation axis R in the rotary soundproof panel unit and thereby the space between the soundproof panel 100 and the outer frame 101, The space between the soundproof panels 100 (when there is no external frame) is opened and the sound is smoothly communicated through the interval where the wind is opened, thereby preventing an unreasonable wind load from acting on the soundproof wall. That is, when a large intensity of wind is blown, the soundproof panel 100 itself of the rotary soundproof panel unit of the present invention rotates by the wind and communicates the wind, and at the same time, the soundproof panel 100 itself, The sound insulation panel 200 constructed using the sound insulation panel 100 of the present invention and the rotary sound insulation panel unit having the sound insulation panel 200 of the present invention can prevent noise from being transmitted through the sound insulation panel 200, It is possible to reduce the strength or the number of struts constituting the soundproof wall 200 compared to the prior art or to construct a soundproof wall of a size higher than that of the prior art As a result, it is possible to greatly reduce the cost of the soundproof wall 200, and the economical efficiency of the construction of the soundproof wall 200 can be greatly improved Hui will be.

In the drawings referred to above, the wind guide member 3 is illustrated as having a triangular shape, but the shape of the wind guide member 3 is not limited to a triangle. Fig. 13 is a schematic perspective view corresponding to Fig. 5 for another embodiment of the present invention in which the shape of the wind guide member 3 is semicircular, and Fig. 14 is a cross-sectional perspective view taken along the line CC of Fig. 13 And FIG. 15 is a schematic cross-sectional view along line CC of FIG. 13, showing a cross-sectional view showing when the wind passes strongly. 13 to 15, in the present invention, the wind guide member 3 may be modified into various shapes such as a semi-circular shape in addition to the triangular shape. 13 to 15 are the same as those of the other embodiments described above, and therefore, a repetitive description thereof will be omitted.
