Description

  The present invention relates to a soundproof panel that is attached to a wall surface that is erected and installed at an edge of a vehicle traveling road such as a road or a railroad, and a soundproof panel mounting structure that is attached to the wall surface.

  On the roads of vehicles such as highways and railways, large noises are generated as the vehicles travel and damage the environment around the roads. For this reason, in order to prevent the noise etc. which generate | occur | produces with driving | running | working of a vehicle from leaking outside, the wall body which consists of concrete, resin, etc. is provided along the extension direction of a vehicle travel path. It is possible to prevent noise generated from the vehicle from passing through the wall to a certain extent only by such wall bodies being erected on both sides of the vehicle travel path, and slightly improve the sound insulation to the outside. It becomes possible.

  However, when there is a private house or the like outside such a vehicle travel path, higher soundproof performance is required, so it is not sufficient to simply stand a wall on the edge of the vehicle travel path. In general, a soundproof panel having a sound absorbing performance is attached to the wall.

  When attaching the soundproof panel to the wall body, for example, anchor bolts are embedded in advance on the vehicle traveling road surface side of the wall body, and L-shaped mounting brackets are provided at both ends of the soundproof panel. A method of fixing a bolt by inserting a bolt hole in a mounting bracket and screwing the bolt hole is proposed (for example, see Patent Document 1). In the disclosed technique of Patent Document 1, the soundproof panel is configured to be horizontally long along the wall surface, filled with a sound-absorbing material, and the front plate facing the vehicle travel path is punched. A number of holes are provided. As a result, noise from the vehicle enters the soundproof panel through this punching hole and is absorbed by the sound absorbing material. Since the rear surface of the soundproof panel has a wall surface behind it, a back plate is not particularly required. For this reason, an internal sound-absorbing material will be hold | maintained via the horizontal frame fitted mainly from the upper and lower sides. Incidentally, in the example shown by this patent document 1, the soundproof panel is continuously arrange | positioned not only in the left-right direction but the up-down direction with respect to the wall body.

  Patent Document 2 discloses a technique for attaching a horizontally long soundproof panel to a wall surface. According to the disclosed technique of Patent Document 2, the sound absorbing material wrapped with the nonwoven fabric is filled inside, the horizontal frame is fitted from above and below, a number of punched holes are formed in the front plate, and the back plate is not particularly required. The soundproof panel is attached to the wall surface. When this soundproof panel is actually attached, for example, anchor bolts are embedded in advance on the vehicle traveling road surface side of the wall body. In addition, the soundproof panel is provided with an attachment portion obtained by bending a plate and connected to an anchor bolt to fix the soundproof panel to the wall surface.

JP 2006-283297 A Japanese Patent Application Laid-Open No. 2004-212336

  As described above, since the soundproof panel shown in Patent Documents 1 and 2 has a wall surface on the back surface thereof, the material cost is often reduced by omitting the configuration of the back plate in particular, and as a result, sound absorption is achieved. The material is exposed from the back. The soundproof panel is configured such that noise from the vehicle passes into the panel by forming a number of punched holes in the front plate as described above.

  However, as shown in FIG. 10, in the soundproof panel 7 in which a large number of such punched holes are formed in the front plate 71 and the back plate is omitted and the sound absorbing material 72 is exposed from the back, the soundproof panel 7 is punched due to rain. Rainwater enters the panel from the front plate through the hole, and rainwater enters directly from the back side. If rainwater enters the panel, the sound absorbing material is exposed to rainwater. Further, when a large amount of rainwater enters the panel, as shown in FIG. 10, water accumulates at the bottom of the horizontal frame 73 for fixing the sound absorbing material 72 from below.

  The water actually collected at the bottom of the horizontal frame 73 can be drained by draining from the drain holes provided at predetermined positions of the horizontal frame 73. However, since the horizontal frame 73 is fitted to the sound absorbing material 72 with almost no gap, the sound absorbing material 72 itself becomes a barrier in guiding the accumulated water to the drain hole, which is effective. It was difficult to drain.

  In addition, there is a method of evaporating the water accumulated at the bottom of the horizontal frame 73 by evaporating it over time, but it may take a considerable number of days until the water actually evaporates. Effective drainage could not be realized.

  In addition, if the horizontal frame 73 is left in a state where water is accumulated, there is a problem that the metal horizontal frame 73 is corroded based on the accumulated water. For this reason, draining the water accumulated in the horizontal frame 73 has been indispensable for extending the soundproof panel structure for a long period of time, but a method that can be effectively realized in a shorter time has been proposed. There wasn't.

  Accordingly, the present invention has been devised in view of the above-described problems, and the object of the present invention is to provide a soundproof panel that is attached to a wall surface that is erected and installed at the edge of a vehicle traveling path, particularly for rain. It is an object of the present invention to provide a soundproof panel capable of effectively discharging rainwater caused by the intrusion into the panel without being accumulated inside, and a soundproof panel mounting structure in which the soundproof panel is mounted on a wall surface.

  In order to solve the above-described problem, a first invention is a soundproof panel that is attached to a wall surface standing on an edge of a vehicle travel path, and is attached to the vehicle travel path side of the wall surface, and is laterally extended along the wall surface. A cross-section groove-type upper and lower engaging parts extending in the direction, and a panel case in which a sound absorbing material is housed and a large number of small holes are formed on the front side, with the upper end being the upper side A sound absorber that is fitted to the engaging part and has a lower end fitted to the lower engaging part, and the lower engaging part is for locking the fitted sound absorbing body. It has a locking part and a drainage channel that opens below the locking part and communicates to both ends in the extending direction and has its discharge port exposed to the outside.

  According to a second invention, in the first invention, the locking portion is bent toward the opening of the drainage channel from the groove-shaped wall surface side and the vehicle travel path side constituting the lower engagement component, or A soundproof panel, which is a protruding piece protruding toward an opening.

  According to a third invention, in the first or second invention, the locking portion is inclined downward toward the drainage channel.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the drainage channel further includes a bottom drainage hole opened at a bottom thereof.

  According to a fifth invention, in any one of the first to fourth inventions, a plurality of the sound absorbers are provided in the extension direction between one upper engagement component and one lower engagement component. It is characterized by being.

  6th invention is a soundproof panel attachment structure which attaches the soundproof panel which concerns on any 1st invention among the 1st-5th to the vehicle travel road side of the wall surface standingly arranged in the edge part of a vehicle travel road, Comprising: By configuring the sound absorber vertically long so that the longitudinal direction is up and down, the soundproof panel is arranged without being continuous in the up and down direction.

  When it rains, rainwater enters directly through the small holes in the front plate and from the back side. As a result, rainwater is absorbed by the sound absorber and falls inside the sound absorber due to its own weight. Then, after the rainwater reaches the lower end of the sound absorber, the rainwater flows down to the drainage channel. In particular, according to the present invention, the drainage channel bulges downward in a convex shape, and the sound absorber is locked via a locking part above the drainage channel, so that rainwater is accumulated in the drainage channel. It is possible to secure a sufficient space above.

  The rainwater flowing down into the drainage channel passes through the drainage channel and is discharged to the outside through the discharge ports at both ends of the drainage channel.

  At this time, by configuring the locking portion to be inclined downward toward the drainage channel, it becomes possible to cause rainwater from the sound absorber to flow toward the drainage channel vigorously, and to reduce the cross-sectional area of the drainage channel. It is possible to secure a large amount.

  As described above, according to the present invention, in the soundproof panel attached to the wall installed upright at the edge of the vehicle running path, even if rainwater due to rain enters the inside of the panel, it is effective without accumulating the inside. Can be discharged automatically.

It is a figure which shows the structural example of the conventional soundproof panel.

  Hereinafter, a soundproof panel as an embodiment of the present invention will be described in detail with reference to the drawings.

  A soundproof panel to which the present invention is applied is disposed on a wall 3 that is erected and arranged at the edge of a vehicle traveling path 10 such as a road or a railroad as shown in FIG. In particular, the soundproof panel 1 is attached to a wall surface 3a on the vehicle traveling path 10 side in the wall body 3, and includes an upper engagement component 11 and a lower engagement component 12, and the upper engagement component 11 and the lower side. And a sound absorber 21 fitted from above and below the engaging component 12.

  2 is an assembly configuration diagram of the soundproof panel 1, FIG. 3 (a) shows an assembly front view thereof, and FIG. 3 (b) shows an assembly side view thereof. FIG. 4 shows a rear view of the soundproof panel 1. 5A is an enlarged cross-sectional view near the upper end of the soundproof panel 1, and FIG. 5B is an enlarged cross-sectional view near the lower end of the soundproof panel 1.

  As shown in FIG. 2, the sound absorber 21 includes a metal panel case 25 and a sound absorbing material 26 encapsulated by the panel case 25.

  The panel case 25 has a front plate 25a, a side plate 25b bent from the front plate 25a in a substantially orthogonal direction, and a direction substantially orthogonal to the side plate 25b and parallel to the front plate 25a. And a lip surface 25c bent in the direction. The front plate 25a faces the vehicle travel path 10 side when disposed, and the lip surface 25c faces the wall body 3 when disposed.

  Incidentally, only the lip surface 25c is formed on the back side facing the front plate 25a, and the so-called back plate is not provided on the entire back side. The reason for this is that the back side faces the wall 3 described above, and therefore, no particular problem arises from the viewpoint of sound insulation even without providing a metal plate over the entire back side. This is also because it is desirable not to provide a metal plate over the entire back side from the viewpoint of reducing the material cost.

  A large number of small holes 30 are regularly arranged in the front plate 25a. Noise from the vehicle travel path 10 can pass through the front plate 25a through the small hole 30. Further, fastening holes 28 for fastening bolts and rivets at predetermined intervals are provided at the upper ends of the front plate 25a and the lip surface 25c, and predetermined intervals are provided at the lower ends of the front plate 25a and the lip surface 25c. A hole 29 is provided. The lip surface 25c is projected from the end of the side plate 25b toward the inside. The sound absorbing material 26 can be held without diffusing via the lip surface 25c.

  The sound absorbing material 26 is made of, for example, rock wool, glass wool, other porous materials, or the like, and may be constituted by wrapping these together with a nonwoven fabric with fine holes as necessary. .

  Incidentally, the panel case 25 may be configured by integrally forming the front plate 25a, the side plate 25b, and the lip surface 25c. Alternatively, the front plate 25a, the side plate 25b, and the lip surface 25c may be formed independently of each other and joined together. At this time, the member composed of the side plate 25b and the lip surface 25c may be configured, for example, in a cross-sectional groove shape.

  The upper engagement component 11 is continuous from the upper end of the upper fixing plate 31, the upper end of the upper fixing plate 31, and is bent in a direction substantially orthogonal to the upper fixing plate 31. And an upper locking plate 33 that is bent in a substantially orthogonal direction and extended so as to be substantially parallel to the upper fixing plate 31. The upper fixing plate 31 is provided on the vehicle traveling road side, and the upper locking plate 33 is provided on the wall surface side.

  The upper fixing plate 31 to the upper locking plate 33 are configured so as to form a substantially bowl-shaped cross section, and are bent into a groove shape so as to draw a substantially U shape in a side view. Incidentally, in the above-described example, it is assumed that the surfaces 31 to 33 constituting the upper engagement component 11 are bent in a substantially orthogonal direction, but the present invention is not limited to this, and the upper top plate 32 is As shown in FIG. 5A, it may be configured to be inclined slightly upward toward the center. Thereby, it becomes possible to flow the rainwater due to the rain smoothly to the outside without accumulating on the upper top plate 32. The upper top plate 32 may be formed with a bolt groove 39 into which a bolt head can be fitted. At this time, the upper engaging part 11 may be provided with an upper frame drain hole 36 for discharging water accumulated in the bolt groove 39 to the outside. The upper fixing plate 31 and the upper locking plate 33 are provided with holes 37 at a predetermined interval. The rivets 51 and 55 can be inserted through the hole 37.

  By fitting the upper engaging component 11 having such a configuration to the upper end of the sound absorbing body 21, the upper end of the sound absorbing body 21 is held between the upper fixing plate 31 and the upper locking plate 33, It will be attached to the sound absorber 21 in a stable state.

  As shown in FIG. 5B, the lower engagement component 12 is continuous from the lower fixing plate 41 and the lower end of the lower fixing plate 41, and is bent in a substantially orthogonal direction with respect to the lower fixing plate 41. A lower bottom plate 42, and a lower locking plate 43 that is bent from the end of the lower bottom plate 42 in a substantially orthogonal direction and extended so as to be substantially parallel to the lower fixing plate 41. Yes. The lower fixing plate 41 to the lower locking plate 43 are configured to form a substantially bowl-shaped cross section, and are bent into a groove shape so as to draw a substantially U shape in a side view. The lower fixing plate 41 is provided on the vehicle travel path side, and the lower locking plate 43 is provided on the wall surface side. The lower locking plate 43 and the lower fixing plate 41 are provided with holes 47 at a predetermined interval. The rivets 52 and 55 can be inserted through the hole 47. The lower bottom plate 42 may be formed with a bolt groove 49 into which a bolt head can be fitted.

  In addition, the lower engagement component 12 includes the lower bottom plate described above including a locking portion 44 for locking the sound absorber 21 to be fitted and a drainage channel 45 opened below the locking portion 44. 42 is formed. The locking portion 44 may be configured in any shape as long as it can lock the sound absorber 21 to be fitted from below with a predetermined height. As a specific shape of the locking portion 44, for example, as shown in FIG. 5B, it is bent from both sides of the lower fixing plate 41 and the lower locking plate 43 toward the opening side of the drainage channel 45. It may be configured. In addition, the locking portion 44 may be configured by a protruding piece that protrudes toward the opening side of the drainage channel 45.

  Further, the locking portion 44 may be inclined downward toward the drainage channel 45 as shown in FIG. As a result, rainwater that has entered the soundproof panel 1 can be smoothly poured into the drainage channel 45.

  The drainage channel 45 may be formed in any configuration as long as it is formed below the locking portion 44 and opens upward toward the sound absorber 21 to be fitted. That is, it bulges in a convex shape toward the lower side than the locking portion 44. The drainage channel 45 is formed by a groove bent in a U-shaped cross section, and has a shape capable of storing rainwater that has flowed down and flowing it. As described above, since the sound absorbing body 21 is supported from below by the locking portion 44, the space between the sound absorbing body 21 and the lower bottom plate 42 bulged in a convex shape toward the lower side. In this case, a flow path on the tunnel suitable for flowing water is naturally formed, and this functions as the drainage channel 45.

  Further, the front form shown in FIG. 3 for both the upper engaging component 11 and the lower engaging component 12 is extended in the lateral direction along the wall surface in the extending direction A of the wall body 3. Similarly, the drainage channel 45 in the lower engagement component 12 is also extended in the extending direction A, and is extended as it is to both ends of the lower engagement component 1. As a result, as shown in the side view of FIG. 3B, the drainage channels 45 appear directly on the both side ends of the soundproof panel 1 and are exposed. That is, both side ends of the drainage channel 45 appear as a discharge port 45a directly exposed to the outside, and rainwater accumulated in the drainage channel 45 can be directly discharged to the outside through the discharge port 45a.

  Incidentally, when the sound absorber 21 is fitted by the upper engagement component 11 and the lower engagement component 12, the upper engagement component 11 is fitted to the upper end of the sound absorber 21, as shown in FIG. The lower engagement component 12 is fitted to the lower end of the sound absorber 21. And the hole 37 by the side of the upper side fixing plate 31 in the upper engaging part 11 and the hole 28 of the sound absorber 21 are put together to fasten the rivet 51, and the hole by the side of the lower fixing plate 41 in the lower side engaging part 12. 47 and the hole 29 of the sound absorber 21 are combined to fasten the rivet 52.

  Similarly, as shown in FIG. 2, the hole 37 on the upper engagement plate 33 side of the upper engagement component 11 and the hole 28 of the sound absorber 21 are aligned to fasten the rivet 55, and the lower engagement component 12 The rivet 55 is fastened by aligning the hole 47 on the lower lower locking plate 43 side with the hole 29 of the sound absorber 21.

  At this time, the present invention is not limited to the case where one sound absorbing panel 21 is fitted to one upper engaging component 11 and one lower engaging component 12 to constitute one soundproof panel 1. For example, as shown in FIG. 3, one soundproof panel 1 may be configured by fitting a plurality of sound absorbers 21 to one upper engagement component 11 and one lower engagement component 12.

  Further, as shown in FIG. 4, each soundproof panel 1 is provided with a frame band plate 53 in order to prevent the sound absorbing material 26 in each sound absorbing body 21 from jumping out from the back and to keep it in a stable state. You may do it. The frame band plate 53 is installed by being installed between the lip surfaces 25c of the panel case 25, and may be attached via, for example, rivets 55.

  Next, the attachment structure with respect to the wall 3 of the soundproof panel 1 which consists of the structure mentioned above is demonstrated.

  As shown in FIG. 6, the soundproof panel 1 is attached to the wall body 3 via attachment fittings 62 attached to the upper and lower ends. 7 shows a detailed configuration of the mounting bracket 62, FIG. 7A is a side view of the mounting bracket 62, and FIG. 7B is a bottom view of the mounting bracket 62. FIG. 7C is a front view of the mounting bracket 62.

  The mounting bracket 62 is made of a metal having an L-shaped cross section including a wall surface abutting plate 66 and a panel attaching plate 67 bent in a direction substantially orthogonal to the wall surface abutting plate 66. The panel attaching plate 67 has a plurality of through holes 68 cut out. Further, the wall surface abutting plate 66 has a long hole 70 cut in the long axis direction in the depth direction in FIG. 7A and in the lateral direction in FIG. 7C. .

  When the soundproof panel 1 is attached to the wall 3 using such a mounting bracket 62, first, bolts 63 are respectively inserted into the bolt grooves 39 in the upper engagement component 11 and the bolt grooves 49 in the lower engagement component 12. Fit. When the bolts 63 are fitted, the bolt heads are fitted into the bolt grooves 39 and 49, respectively, and the feet of the bolts 63 are inserted into the through holes 68 of the panel attachment plate 67 in the mounting bracket 62. . As a result, the foot of the bolt 63 protrudes from the panel attachment plate 67, and the bolt 63 is fixed by screwing a nut 69 onto the foot. In this manner, the mounting brackets 62 are respectively attached to the upper and lower ends of the soundproof panel 1.

  Next, the wall surface abutting plate 66 is brought into contact with the wall surface of the wall body 3, and the anchor bolt 61 is inserted into the long hole 70 in the wall surface abutting plate 66 to be driven and fixed in the wall body 3. It becomes. As a result, the soundproof panel 1 is attached to the wall 3.

  It should be noted that the heads of the bolts 63 are slightly loosely fitted in the bolt grooves 39 and 49 so that the bolt grooves 39 and 49 are used as rails, and the soundproof panel 1 is directed in the depth direction in FIG. Can be shifted. Further, the mounting bracket 62 can be finely corrected with respect to the anchor bolt 61 by using the long hole 70 as a rail.

  According to the present invention having the above-described configuration, the noise from the vehicle travel path 10 passes through the front plate 25 a through the small hole 30 and is absorbed by the internal sound absorbing material 26. As a result, the noise-reducing effect of the soundproof panel 1 and the presence of the wall body 3 can strongly prevent noise from the vehicle travel path 10 from leaking to the outside.

  The soundproof panel 1 is provided with a large number of small holes 30 in the front plate 25a, and a special back plate is not provided on the back side. For this reason, when it rains, as shown in FIG. 8, rainwater enters directly from the small holes 30 of the front plate 25a and from the back side. As a result, rainwater is absorbed by the sound absorber 21 and falls inside the sound absorber 21 in the direction of the arrow due to its own weight. Then, after the rainwater reaches the lower end of the sound absorber 21, the rainwater flows down to the drainage channel 45. In particular, according to the present invention, the drainage channel 45 bulges downward in a convex shape, and the sound absorber 21 is locked via a locking part 44 above the drainage channel 45. It is possible to secure a sufficient space for accumulating rainwater.

  The rainwater flowing down into the drainage channel 45 passes through the drainage channel 45 and is discharged to the outside through the discharge ports 45 a at both ends of the drainage channel 45.

  At this time, by configuring the locking portion 44 to be inclined downward toward the drainage channel 45, rainwater from the sound absorber 21 can flow down toward the drainage channel 45 vigorously, and the drainage channel. It is also possible to ensure a large cross-sectional area of 45.

  As described above, according to the present invention, in the soundproof panel attached to the wall installed upright at the edge of the vehicle running path, even if rainwater due to rain enters the inside of the panel, it is effective without accumulating the inside. Can be discharged automatically.

  Further, in order to discharge rainwater accumulated in the drainage channel 45, for example, a bottom drainage hole 101 as shown in FIG. 5B may be provided at a predetermined location. As a result, rainwater can be discharged from the bottom drain hole 101, and further, the rainwater in the drainage channel 45 can be drained by flowing to both ends in the extending direction A, and water can be collected in the drainage channel 45 more. It can be effectively prevented.

  The soundproof panel 1 to which the present invention is applied is not a technique based on the premise that the soundproof panel 1 is arranged in a plurality of stages in the vertical direction of the wall surface. This is because if the soundproof panel 1 is arranged in a plurality of stages in the vertical direction, rainwater discharged from the soundproof panel 1 arranged in the upper stage is received by the soundproof panel 1 arranged in the lower stage. Further, when the bottom drain hole 101 is provided in the drainage channel 45, it is difficult for rainwater discharged from the bottom drain hole 101 to be effectively drained by the soundproof panel 1 disposed in the lower stage as a barrier. It is to become. For this reason, in the present invention, each sound absorber 21 is configured to be vertically long so that the longitudinal direction is vertical, instead of being arranged in multiple stages in the vertical direction of the wall surface. By configuring the ratio at this time such that the vertical direction becomes longer, the soundproof panel 1 can be configured in a single stage without being vertically connected.

  FIGS. 9A to 9C show examples of other shapes in the lower engagement component 12. FIG. 9A shows that the locking portion 44 is configured to be bent from the lower locking plate 43 toward the opening of the drainage channel 45 and inclined downward, and from the lower fixing plate 41 to the opening. It is comprised by the protrusion piece formed by protruding toward. By configuring the locking portion 44 with such a projecting piece, the lower side of the projecting piece can also be configured with the drainage channel 45, and as a result, the cross-sectional area of the drainage channel 45 can be increased. Become.

  Further, in the example of FIG. 9B, the locking portion 44 as the projecting piece is the same as that of FIG. 9A except that the locking portion 44 is inclined downward. In this example, it is possible to allow rainwater to flow toward the drainage channel 45 more effectively by inclining the locking portion 44 as a protruding piece downward.

  In the example of FIG. 9C, the drainage channel 45 is divided into two parts, and the locking portion 44 is a protrusion slightly protruding from the lower fixing plate 41 and the lower locking plate 43. It is comprised by the installation piece 44a and the protruding part 44b which was provided between this drainage channel 45, and was raised to the height substantially the same as a protrusion piece. The lower side of the raised portion 44b is a bolt groove 49 for fitting the head of the bolt 63, but in the example of FIG. 9C, the bolt groove can be positioned substantially at the center. Become.
