Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sound insulation panel that is installed on a shoulder or side wall of an expressway and blocks noise from a traveling automobile or the like, and a mounting structure for the sound insulation panel.
[0002]
[Prior art]
Conventionally, in order to prevent noise from an automobile traveling on a highway from being transmitted to houses around the road, sound insulation panels have been spread along the road on both sides of the road. Specifically, pillars of a certain height made of H-shaped steel are erected at regular intervals in the longitudinal direction of the road on both sides of the road, and are formed by the web part and the flange part of the adjacent pillars. By sequentially fitting the end portions of the sound insulation panels into the grooves, a plurality of sound insulation panels are stacked in a column to form a sound insulation wall.
[0003]
Furthermore, when the automobile collides with the sound insulation panel stretched in this way, the sound insulation panel is refracted and deformed, and may be detached from the support column and fall downward. Measures are taken to prevent falling. For example, as described in Japanese Patent Application Laid-Open No. 9-151418, the end of the striated body provided with a striated portion of a striated body made of a wire rope in the vertical frame portions on both sides of the sound insulation panel and respectively inserted into the sunk portion A sound insulation panel drop prevention means is known in which the vertical frame portion of the sound insulation panel is fixed to the support column and can be separated from the end portions of the top and bottom horizontal frame portions of the sound insulation panel. .
[0004]
When an automobile collides with the sound insulation panel and the sound insulation panel is deformed, the ends of the upper and lower horizontal frame portions are placed in the vertical direction with one vertical frame portion left in the vertical groove of the column by the cable body. Separated from the frame portion, and another sound insulation panel portion other than the one vertical frame portion on the other column side, inserted into the other vertical frame portion fitted in the vertical groove of the column, It is configured to be supported and prevented from falling.
[0005]
[Problems to be solved by the invention]
However, in the sound insulation panel fall prevention means as described above, the strips are vertically inserted into the vertical frame portions on both sides of the sound insulation panel, and these cord bodies are fixed to the support columns. If the vertical frame part is fixed to the upper and lower horizontal frame parts with the same strength, if the sound insulation panel is refracted and deformed into a plane V shape due to a collision with an automobile, etc. Since it is stretched and fixed in the length direction, a large force acts in the direction of shearing the striated body at the penetrating part of the vertical frame part on both sides through which this striated body is inserted, and it penetrates by the acting force The part of the sound insulation may be detached from the penetrating part, or the vertical frame on both sides of the sound insulation panel may be disengaged from the top and bottom horizontal frame parts and the sound insulation panel may be separated from the line body and fall. There is.
[0006]
For this reason, one vertical frame portion is structured to be separably connected as described above without being fixed to the upper and lower horizontal frame portions. However, with such a structure, the strength of the entire sound insulation panel is reduced, and the sound insulation panel Even if the impact force acting on the sound is small, there is a possibility that the sound insulation panel will be disassembled and it will not be possible to exhibit an effective buffering action, which is problematic in practical use. In addition, it is extremely difficult to vertically penetrate the cable body in the vertical frame portions on both sides of the sound insulation panel, and there is a problem that a great deal of labor and labor is required for the construction.
[0007]
The present invention has been made in view of such problems, and the object of the present invention is to easily and firmly perform the construction on the pillars standing on the side of the expressway and to receive impact force. In addition, it is possible to reliably prevent a fall from the expressway, and to provide a sound insulation panel having a simple structure and a mounting structure for the sound insulation panel.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a sound insulation panel according to the present invention comprises, as described in claim 1, a sound insulation plate stretched on a rectangular frame formed by upper and lower horizontal frame members and both side vertical frame members.

[0009]
In the sound insulation panel configured as described above, the invention according to claim 2 is characterized in that the horizontal guide groove member fixed to the rear side upper end of the upper horizontal frame member of the sound insulation panel has a length shorter than the lateral width of the sound insulation panel. In addition, while the upper end is formed in a U-shaped cross section having a guide groove that is fully open at the upper end, the ring body is formed from an eyebolt. At the outer side surfaces of the vertical frame members on both sides of the sound insulation panel, they are superposed on the vertical surfaces facing the road side of the columns that stand on the expressway at regular intervals in the length direction of the road, and are fixed to the columns with bolts. The side frame material is provided integrally.
[0010]
The invention according to claim 4 is the mounting structure of the sound insulation panel, wherein a sound insulation plate is stretched on a rectangular frame formed by the upper and lower horizontal frame members and the both side vertical frame members, and the upper horizontal frame A sound insulation panel having a horizontal guide groove member fixed to the back side of the material and annulus projecting rearward on both sides of the horizontal guide groove member is erected on the expressway at regular intervals. The strut is arranged between the vertical surfaces facing the road side in a erected state and fixed with bolts, and the strut body is inserted into the insertion hole provided on the opposing surface of the strut to guide the strut body to the horizontal guide. The structure is such that the groove member is inserted and locked into the ring body on both sides of the horizontal guide groove member.
[0011]
[Action]
When the sound insulation panel is stretched between adjacent struts that are erected on the side of the expressway at regular intervals, the vertical frame members on both sides of the sound insulation panel are inserted into the vertical grooves facing each other. Rather than being stretched by this, the vertical frame members are stretched by being applied to the vertical surfaces of the columns facing the road and fixed with bolts. Therefore, it is possible to efficiently perform the work of installing the sound insulation wall by attaching a plurality of sound insulation panels in a column to adjacent columns.
[0012]
Further, the sound insulation panel has a horizontal guide groove member of a rope body for preventing sound insulation panel dropping attached to the rear upper end of the upper lateral frame member, and a ring through which the rope body is inserted on both sides of the guide groove member. Since the body is protruding, when the sound insulation panel is stretched between the struts, the rope body such as a wire rope is received in the horizontal guide groove member in a horizontally inserted state, and the rope body is attached to both sides. By passing through the other ring body and extending in the horizontal direction through the insertion hole provided in the support column, it is possible to easily and reliably perform the fall prevention means of the sound insulation panel by the cable body on the support column.
[0013]
In addition, it is possible to prevent falling of a large number of sound insulation panels arranged in parallel in the horizontal direction between the struts by stretching a single cable body horizontally through the insertion holes of several to several tens of struts. it can.
[0014]
When an automobile or the like collides with the sound insulation panel stretched in this way, the sound insulation panel is attached with the vertical frame members on both sides in contact with the vertical surfaces of the columns facing the road. In addition to exhibiting an excellent buffering function, even if the sound insulation panel is detached from the struts due to a large impact force, the strips are stretched horizontally between the struts. Since the provided ring body is inserted, the sound insulation panel removed from the support can be reliably prevented from being suspended and dropped by the cable body via the ring body.
[0015]

[0020]
On the other hand, as shown in FIG. 4 and FIG. 5, the support column B is a H-section steel that protrudes at right angles toward both sides at both ends of a web portion b1 having a constant width and is integrally provided with flange portions b2 and b3. And one flange part b2 is erected with the road facing the highway, and at the same interval as the bolt insertion hole 10 provided in the flange part 8b of the sound insulation panel A in the flange part b2. Accordingly, the bolt insertion holes 11 are provided at regular intervals in the length direction. Furthermore, the ridge body insertion hole 12 is provided in the web part b1 of each support | pillar B for every vertical width space | interval of the sound insulation panel A to an up-down direction.
[0021]
Next, a procedure for extending the sound insulation panel A between the struts B adjacent to each other along the expressway will be described. First, as shown in FIG. 4 and FIG. 5, the sound insulation panel A has a vertical portion of the opposite half of the flange portion b2 facing the road side of the support columns B and B with the flange portions 8b of the side frame members 8 and 8 facing each other. The sound insulation panel A is attached to the column B by bringing the bolt insertion holes 10 and 11 extending through the flange portions 8b and b2 into contact with each other and fixing them with bolts and nuts 13 respectively. , B is stretched between the flange portions b2 and b2. In the same manner, the sound insulation panels A are stacked in the same manner, and the sound insulation panel A is stretched between the right and left columns B and B. Next, the end portion of the cable body C is pulled out through the insertion hole 12 provided in the web portion b1 of the support B, and the end portion of the cable body C is one side of the upper end portion on the back surface side of the sound insulation panel A. After passing through the horizontal guide groove member 6 from the ring body 7 to the other ring body 7, it is opposed to the insertion hole 12 of the one strut B through which the cable body C is inserted on the horizontal line. It is made to pass through the insertion hole 12 of the other column B.
[0022]
In the same manner, the cable body C inserted into the other support column B in the same manner is one ring body of the sound insulation panel A stretched between the support column B and the next support column B adjacent to the support column B. 7, the horizontal guide groove member 6, the other ring body 7, and the next support column B, and this operation is performed on each adjacent support column B and B and the sound insulation panel A stretched between them. The cable body C is attached to the sound insulation panel B. The cable body C is fixed by welding or the like in a state where both ends thereof are inserted into the insertion holes 12 of the column B where the ends are located.
[0023]
In this way, as shown in FIG. 3, the plurality of sound insulation panels A are stretched in a stacked state between the flange portions b2 and b2 of the adjacent columns B and B, and each mounting height is set. At this position, it is connected in a state where the ring bodies 7 and 7 are inserted into both sides of the cable body C stretched horizontally between the columns B and B, and the sound insulation panel A in the laminated state is connected to the road. A sound insulation wall having an integral height is formed on a side portion of the road, which is disposed in a continuous state between the columns along the length direction. And since the cable body C is inserted in the horizontal guide groove member 6 of the back surface side upper end part of the sound-insulation panel A, the cable body C does not hang down and can be seen from the road.

For example, when an automobile collides with the sound insulation wall configured in this manner, the vertical frame members 3 and 4 of the sound insulation panel A and the side frame members 8 and 8 fixed to the flange portion b2 of the column B are integrally connected. A large shearing force acts on the bolt 9, and this part becomes the weakest part of the sound insulation panel A and destroys the mounting part of the bolt while the vertical frame members 3 and 4 are separated from the side frame members 8 and 8, It is pushed out in a state of being refracted toward the outside of the road, but the cable body C is stretched horizontally between the columns B and B, and the cable body C projects from both sides of the upper end of the sound insulation panel A. Since the ring bodies 7 and 7 are inserted and supported, the sound insulation panel A does not fall down even if the sound insulation panel A is detached from the pillars B and B on both sides, and the state suspended by the cable body C is supported. It is to hold.
[0025]
Furthermore, even if the sound insulation panel is refracted when it receives an impact force, the ring bodies on both sides move along the rope body according to the degree of the refraction, and therefore, an unreasonable force on the rope body and the ring body. It is possible to prevent the sound insulation panel from dropping due to the removal of the ring from the sound insulation panel.
[0026]
In addition, since the sound insulation panel A in the above embodiment has a structure in which the horizontal guide groove member 6 is directly fixed at the center of the upper surface of the back side of the upper horizontal frame member 1, as shown in FIG. In the state where 8 and 8 are attached to the flange portions b2 and b2 of the columns B and B, the horizontal guide groove member 6 is positioned on the road side with respect to the cable body insertion hole 12 provided in the columns B and B. The strip C inserted through the B insertion hole 12 is refracted toward the road, and is inserted into the ring 7. Accordingly, depending on the opening size of the ring 7, the strip C may be horizontal. Since there is a possibility that the guide groove member 6 may come off from the side end portion, it is preferable that the end portion of the horizontal guide groove member 6 is covered with at least a cover member.
[0027]
Further, as shown in FIGS. 6 to 8, an auxiliary horizontal frame member 14 having a predetermined width is fixed to the back surface of the upper horizontal frame member 1 of the sound insulation panel A ′, and the length of the auxiliary horizontal frame member 14 on the back surface is fixed. A horizontal guide groove member 6 for supporting the sound insulation panel fall prevention rope body C is fixed to the central portion in the vertical direction, and the rope is formed on both sides of the back surface of the auxiliary horizontal frame member 14 on both sides of the horizontal guide groove member 6. Rings 7 and 7 through which the body C is inserted project, and the positions of the horizontal guide groove member 6 and the rings 7 and 7 are provided on the columns B and B on which the sound insulation panel A ′ is stretched. You may comprise so that it may arrange | position on the horizontal line which connects between the stripe body penetration holes 12 and 12. FIG. Since other structures are the same as those of the sound insulation panel A, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.
[0028]
In any of the above-described embodiments, the cord body C is connected to one strut by forming the ring bodies 7 projecting on both sides of the upper end on the back side of the sound insulation panels A and A ′ in a closed shape. The ring 7 is inserted while being drawn in the length direction from the side toward the other column, but instead of the ring 7, the opening is partially larger than the diameter of the cable body C. A hook body having an opening may be provided in a projecting manner, and a claw piece may be attached to the opening so as to be freely opened and closed, and the claw piece may be urged in a direction that always closes the opening by a spring force.
[0029]
When such a hook body is provided on both sides of the upper end of the back surface of the sound insulation panel A, A 'on the upper side frame 1, the sound insulation panel A, A' is stretched on the adjacent columns B, B. The strut body C is tensioned in advance in the strut insertion holes 12 and 12 of the struts B and B, and the hook body on both sides is received while receiving the strut body C in the horizontal guide groove member 6. By pressing the claw piece against the peripheral portion of the ridge body C, the claw piece can be opened against the spring force so that the ridge body C can be inserted into the hook body. It is possible to more smoothly and reliably carry out the stretching work of the cable body C and the sound insulation panels A and A ′ between B and B.
[0030]
In addition, although one insertion hole 12 is provided in the web portion b1 of the support B, the insertion member 12 having a larger hole diameter is further provided, and the rope member C is wound around the insertion hole in a loop shape. Can be securely fixed to the column B.
