  However, according to such a sound insulation panel, both side end portions and lower end portions are fixed to both side vertical frame members and lower side frame members by bolts, but these both side vertical frame members, pressing edges and lower sides Since the support structure is simply sandwiched between the horizontal frame member and the pressing edge, when the automobile collides with the sound insulation plate, the sound insulation plate has an upper end portion fixed to the upper horizontal frame material by a plurality of bolts. While bending and deforming into a V-shaped cross section as a fulcrum, it is easy to absorb the impact force from both side edges and bottom edge between the vertical frame material and the pressing edge, and between the lower horizontal frame material and the pressing edge. The sound insulation board breaks and scatters in some cases, which causes a problem in terms of safety.

  In order to prevent the sound insulation plate from coming out of the rectangular frame, the four end portions of the sound insulation plate are firmly fixed to the upper and lower horizontal frame members and both vertical frame members constituting the rectangular frame with bolts. However, if the sound insulation plate is made of a resin plate having a large expansion and contraction rate due to heat like polycarbonate resin, the sound insulation plate may be deformed in a wavy shape due to the expansion and contraction, and the appearance may be significantly impaired. In addition, there is a problem in that the impact force is concentrated on the fixing portion by the bolts at the four end portions of the sound insulation plate, and the sound insulation plate is cracked or broken.

And a sound insulation panel that can effectively absorb the expansion and contraction of the sound insulation plate caused by a temperature difference between winter and summer and prevent the sound insulation panel from being deformed into a wavy shape. It is in. Another object is to provide a sound insulation panel that has a simple structure and is easy to assemble and install.

  In order to achieve the above object, the sound insulation panel according to the present invention, as described in claim 1, overlaps the upper and lower pressing edges on the upper and lower ends of the synthetic resin sound insulating boards, and only the upper pressing edges are used. These screws are fixed to the sound insulation plate, and the screws which are fixed to the both end portions of the sound insulation plate in the vertical direction at predetermined intervals are overlapped by overlapping both sides of the sound insulation plate on the rear surface of the both ends of the sound insulation plate. Are inserted into the oblong holes provided at predetermined intervals in the vertical direction so as to be slidable in the length direction of the oblong holes, and the screws are connected to the rear surfaces of both end portions of the sound insulating plate by the screws. In addition, the upper and lower frames are arranged on the front side of the upper and lower ends of the sound insulating plate, respectively, and the upper and lower ends of the sound insulating plate are interposed between the rear surfaces of the upper and lower frames and the front surface of the upper and lower pushing edge members. While the upper and lower pushing edge materials are fixed to the upper and lower frames, respectively, The side plate portions of the strip are adapted to secure the post.

  In the sound insulation panel configured as described above, the invention according to claim 2 is characterized in that the upper and lower pressing edge members, the upper and lower frames, and both side pressing edge members are formed from a section steel material having an L-shaped cross section having a certain length. The vertical front plate portion of the upper and lower pushing edge members is applied to the rear surfaces of the upper and lower end portions, respectively, and only the upper pushing edge material is fixed to the sound insulating plate, and the both side pushing edges are disposed on the rear surfaces of both side end portions of the sound insulating plate. The vertical front plate portions of the material are overlapped with each other, and screws fixed to both end portions of the sound insulating plate are slidably mounted in the laterally long holes provided in the vertical front plate portion. With the material arranged on the rear side of the upper and lower frames, the upper and lower frames in the state in which the receiving grooves at the upper and lower ends of the sound insulating plate are formed between the vertical front plate portions facing the upper and lower frames and the upper and lower pushing edge members, respectively. Backward from the vertical front plate with the vertical pushing edge The horizontal plane plate portions that are refracted are overlapped and fixed to each other, while the front surfaces of both end portions of the sound insulating plate are in contact with the rear surface of the flange portion of the column having an I-shaped cross section. A side plate that is refracted rearward from a vertical front plate in the material is fixed to a flange portion of the column.

  In the sound insulation panel configured as described above, the invention according to claim 3 is characterized in that the collar member is slidably inserted in the lengthwise direction of the laterally long hole in the laterally long hole provided in the both side pushing edge material. The screw member is inserted into the collar member with screws fixed to both ends of the sound insulation plate, and the nut is screwed into the screw to push the edge material through the collar member. It is characterized by being clamped with a predetermined clamping force slidable in the direction.

  In addition, the upper and lower edges are overlapped on the rear surfaces of the upper and lower ends of the sound insulation plate, and only the upper edge material is fixed to the sound insulation plate, and the both sides are overlapped on the rear surfaces of both ends of the sound insulation plate. Screws, which are fixed at predetermined intervals in the vertical direction at both ends of the sound insulation plate, can slide in the lengthwise direction of the horizontal holes in the horizontal elongated holes provided in the vertical direction at these predetermined intervals. Since the automobile and the like collide with the sound insulation plate, the sound insulation plate is refracted into a V-shaped cross section by the impact force, and both end portions thereof are formed between the flange portion of the support column and the both side pushing edge members. When trying to escape inward from between the opposing surfaces, the screws fixed to both ends of this sound insulation plate have a large slip resistance against the laterally long holes provided at both ends of the both-side pushing edge material. Therefore, the impact force is relaxed by the resistance force at this time. Absorbed to be able to prevent the scattering cracked sound insulating plate.

  Further, the screws fixed to the both end portions of the sound insulating plate are not fixed to the both side pushing edge members attached to the support column, and as described above, the horizontal oblong holes provided in the both side pushing edge members are inserted into the horizontally long holes. Since it is slidably mounted in the length direction, that is, in the left-right direction, and the lower end of the sound insulation board is not fixed to the lower pushing edge material, the temperature difference between the summer and winter seasons is similar to polycarbonate resin. In the case of a resin plate having a large expansion and contraction rate, it is possible to prevent the sound insulation plate from being deformed in a wavy shape by smoothly expanding and contracting in the left and right direction and the up and down direction. It is possible to maintain the tensioned state.

A sound insulation panel which can be performed and whose structure is extremely simplified can be configured.

  Further, since the side plate that is refracted rearward from the vertical front plate in the both side pushing edge material is configured to be directly fixed to the web portion of the column, the construction work of the sound insulation panel on the column has been described above. Can be performed efficiently and accurately.

  According to the invention of claim 3, the collar member is slidably inserted in the lengthwise direction of the laterally long hole in the laterally long hole provided in the both side pushing edge material, and both sides of the sound insulating plate are inserted into the collar member. With a screw fixed to the end being inserted, a nut that is screwed to the screw is used to tighten the pressing edge material through a collar member to a predetermined tightening that allows the screw to slide in the lengthwise direction of the laterally long hole. Since it is clamped with an applied force, it is possible to prevent the tightening force by the nut, that is, the clamping force against the pressing edge material from being increased more than necessary by the collar member, and an automobile or the like collides with the sound insulation board. When this occurs, the pulling resistance force when the screws fixed to the both end portions of the sound insulation plate are pulled inward along the laterally long hole of the pushing edge member due to the impact force, that is, against the oblong hole of the pushing edge member Adjust the slip resistance to a predetermined resistance Rukoto can.

  It should be noted that the pressing edge material is moved back and forth through the collar member inserted in the laterally long hole provided in the pressing edge material by the tightening force of the nut screwed to the screw fixed to the both end portions of the sound insulating plate. When clamping from the surface, a washer, rubber packing, etc. are interposed between the opposing surfaces of the nut and collar member, and the tightening force of the nut acts on the front and rear surfaces of the edge material via these washers and rubber packing.

  In addition, the lower frame 10 also has the length direction in the width direction of the sound insulating plate 1 and one of the horizontally long rectangular plates facing the front (front) side in the same manner as the lower pushing edge member 3. The vertical front plate portion 10a is a vertical front plate portion 10a, and the other flat horizontally long horizontal plate portion 10b is refracted from the lower end of the vertical front plate portion 10a at a right angle toward the rear. By arranging the vertical front plate portion 3a of the lower pushing edge member 3 in parallel at a distance wider than the thickness of the sound insulating plate 1 from the rear surface of the face plate portion 10a, these vertical front plate portions 3a, 10a are arranged in parallel. A receiving groove 15 at the lower end of the sound insulating plate 1 is formed between them, and in this state, the lower surface of the horizontal plate portion 3b of the lower pushing edge member 3 is superimposed on the upper surface of the horizontal plate portion 10b of the lower frame 10. The horizontal plate portion 3b of the lower pushing edge material 3 is fixed to the horizontal plate of the upper frame 10 at regular intervals in the left-right direction by a plurality of screws 12 as one of the fixing tools. It is integrally fixed to the lower surface of 10b. Further, in the receiving groove 15, an elastic sealing material 16 is interposed between the opposing surfaces of the vertical front plate portion 10 a of the lower frame 10 and the lower end portion of the sound insulating plate 1.

  The width of the sound insulating plate 1 is wider than the length of the upper and lower pushing edge members 2 and 3 and the upper and lower frames 9 and 10 formed to be the same length as the upper and lower pushing edge members 2 and 3, and both end portions thereof. Is protruded by a certain width outward from both side end surfaces of the upper and lower pushing edge members 2 and 3 and the upper and lower frames 9 and 10, and is one of fixing members at predetermined intervals in the vertical direction at both side end portions. As shown in FIGS. 2 and 4, the screws 6 are fixed, and the screws 6 protrude rearward, and the protruding screw shaft portions are arranged in a superposed state on the rear surfaces of both end portions of the sound insulating plate 1. Both ends of the sound insulating plate 1 are sandwiched from the front and rear surfaces by a pair of upper and lower nuts 8, 8 which are inserted into the laterally long holes 7 of the both side push-edge members 4, 4 and screwed into the screws 6. Both side pushing edges 4 and 4 are connected to the rear surface of the portion.

  The side edges 4 and 4 are made of a steel material having an L-shaped cross section having a constant length substantially equal to the length between the upper and lower frames 9 and 10, and as shown in FIG. A vertical front plate portion 4a, 4a having a vertically long rectangular shape facing the vertical width direction 1 is superimposed on the rear surface of each side end portion of the sound insulation plate 1 through the sealing material 17 as described above.

The nuts 8 and 8 can be clamped to the pushing edge material 4. Therefore, when the automobile or the like collides with the sound insulation plate 1, the screw 6 fixed to both end portions of the sound insulation plate 1 is drawn inward along the laterally long hole 7 of the pushing edge member 4 by the collision force. The tightening force of the nuts 8 and 8 can be adjusted so that the pulling resistance force at the time, that is, the slip resistance force against the laterally long hole 7 of the pushing edge member 4 becomes a predetermined resistance force.

  Such slip resistance may be generated by a crimping force that crimps the nuts 8 and 8 to the front and rear peripheral surfaces of the laterally long hole 7 via a washer or rubber packing, and the collar member 21 can be elastically deformed. It is formed by a member and is formed slightly longer than the thickness of the vertical front plate part 4a of the pressing edge member 4, and the collar member 21 is deformed in the diameter increasing direction by the tightening force of the nuts 8 and 8, so that it is horizontally long.
