Description

  The present invention relates to a translucent sound insulation wall that is erected along a roadside portion of an expressway, a general road, a railroad, etc., and prevents noise pollution caused by traveling of a vehicle, and in particular, opens a field of view to the outside world. The present invention relates to a translucent sound insulation wall constructed by attaching a translucent sound insulation panel.

  Conventionally, sound insulation walls have been installed on roadsides of highways, ordinary roads, railways, and the like in order to prevent noise associated with vehicle travel. In particular, in this sound insulation wall, a light-transmitting sound insulation wall using a light-transmitting material such as polycarbonate or glass as a panel material is frequently used from the viewpoint of improving the view from the vehicle so that the outside view can be opened. It is like that.

  When such a translucent sound-insulating wall is actually erected and arranged on the side of a road or the like, a translucent panel is fitted and fixed between columns made of H-shaped steel or the like. Specifically, a translucent panel is dropped from above into a groove surrounded by a flange and a web constituting an H-shaped steel as a support and fitted and fixed.

  However, in such an assembling method in which a translucent panel is inserted and dropped into the groove portion of the support column from above, a space for fitting the translucent panel is required above the support column. For this reason, for example, when highways cross each other, the other elevated highway may be disposed immediately above one highway. When a translucent sound insulation wall is installed at such an intersection, if the other elevated highway is located immediately above, a space for fitting the above translucent panel cannot be secured. . For this reason, in such a crossing part, there exists a problem that a translucent sound-insulating wall cannot be installed upright by the assembly method which inserts and fits a translucent panel in the groove part of a support | pillar from the top.

  For this reason, a sound insulation panel mounting structure that can be fitted without inserting the sound insulation panel into the groove of the support column from above has been proposed (for example, see Patent Document 1). According to the technique disclosed in Patent Document 1, a side frame member 182 having a U-shaped cross section is fixed to the outer surface of the sound insulation panel 181 with bolts 183 as shown in FIG. When this is attached to the column 91 made of H-shaped steel, the flange 182a of the side frame member 182 is brought into contact with the flange 92 on the vehicle traveling side (road side) of the column 91, and these are mutually connected by bolts 93. Join. Similarly, the other sound insulation panel 181 located above the sound insulation panel 181 is also joined to the support column 91 via the flange 182a of the side frame member 182.

  According to the disclosed technique of this Patent Document 1, the sound insulation panel 181 can be brought into contact with the predetermined height of the support column 91 from the road side and fixed through the bolt 93, and in the extension direction of the road. Other adjacent sound insulation panels 181 can be continuously connected in the extending direction and connected by a cord-like body. For this reason, it becomes possible to join the sound insulation panel to the groove portion of the support column without inserting it from above as in the above-described prior art.

  Patent Document 2 discloses an example in which a frame member sandwiching a sound insulation panel is attached to a column made of H-shaped steel. The technology disclosed in Patent Document 2 is intended to prevent the sound insulation panel from coming out of the frame material when the vehicle collides. Generally, when the frame material and the sound insulation panel are fixed firmly through bolts, when the vehicle collides with this, stress concentrates on the bolt fixing portion of the sound insulation panel and breaks. There is a fear. For this reason, in the disclosed technique of Patent Document 2, a pull-out resistor piece having an L-shaped cross section made of an aluminum material is provided at both end portions of the sound insulation panel, and the other end side of the pull-out resistor piece is loosely fitted to the frame member. This makes it possible to prevent the sound insulation panel from coming out without damaging it. Similarly, in the technique disclosed in Patent Document 2, a sound insulation panel can be attached to the column from the road side. For this reason, according to the technology disclosed in Patent Document 2, it is possible to join the sound insulation panel to the groove portion of the support column without inserting from above, a viaduct or the like exists above the support column, and a space for construction is provided. Even when it cannot be ensured, the sound insulation panel can be joined.

  However, since the disclosed techniques of Patent Documents 1 and 2 described above are both configured so that the sound insulation panel protrudes greatly from the column to the road side, the road on which the vehicle actually travels is pressed by the sound insulation panel, and the road side There is a risk of violating architectural limits. For this reason, when the vehicle deviates from the correct traveling direction due to an accident or the like and abnormally approaches the sound insulation wall, the tire not only contacts the curb at the bottom of the sound insulation wall, but also the sound insulation panel protruding toward the road Sometimes approached. In particular, in a curved section where the road surface is inclined, the traveling vehicle is also inclined accordingly. For this reason, when a vehicle deviates from the correct traveling direction and abnormally approaches the sound insulation wall at a location where the road is inclined, a part of the vehicle comes into contact with the sound insulation wall protruding toward the road side. There was a risk of it.

  Among the sound insulation walls, translucent sound insulation walls have the effect of improving the view from the vehicle by allowing the driver to see the scenery outside the road, reducing the feeling of pressure that the driver receives while driving effective.

  However, as in the disclosure techniques of Patent Documents 1 and 2, when being arranged in a state of projecting from the support to the road side, a translucent panel is arranged at a location closer to the driver than the support. Become. Usually, the line-of-sight angle (view angle) of the driver who views the scenery outside the road through the translucent sound insulation wall is just a viewing angle obliquely forward from the driver's seat. For this reason, in the vicinity of the column located closer to the driver, the frame material of the translucent panel is projected on the road side, the viewing angle from the driver is narrowed, and the driver is dismissed. A feeling of oppression is given, and the view is harmed. In addition, in the vicinity of the support column located on the deeper side as seen from the driver, the viewing angle is widened because the frame material of the translucent panel is projected on the road side. However, because there is a private side flange in the support column located on the back side, the view itself is not improved, and the groove of the H-shaped steel that forms the support column enters the field of view through the translucent panel, and the driver There was a problem that the viewability of was reduced.

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is, for example, that highways intersect with each other and the other elevated road is located immediately above one road. Even if it is not possible to secure a space for fitting the translucent panel above the post, it can be attached to the post and the translucent panel projects over the road side. An object of the present invention is to provide a translucent sound insulation wall that can satisfy the architectural limit by preventing the failure and improve the viewing performance.

  In order to solve the above-described problems, the present inventor attaches a translucent panel provided with a frame material on four sides of the translucent plate between the columns, and the translucent panel is formed into an H shape that constitutes the column.

  The translucent plate 11 is made of transparent resin such as acrylic or polycarbonate, glass, or the like. The translucent plate 11 has a rectangular shape, and its upper end is sandwiched between the upper frame 12 and its lower end is sandwiched between the lower frame 13. Further, the translucent plate 11 is sandwiched between the vertical frames 14 and 15 at the left and right ends.

  The upper frame 12 is made of metal, and has an upper surface 41 that is inclined as shown in the cross-sectional view of FIG. Further, the lower surface 42 is formed in a planar shape so that the upper ends of the vertical frames 14 and 15 are brought into contact with each other, and a screw hole 43 for fixing with a screw 44 is provided. A groove 45 is provided upward from the lower surface 42. The groove 45 is provided to fix the light-transmitting plate 11 in a state where the upper end of the light-transmitting plate 11 is inserted and held. A pushing edge 46 having a substantially L-shaped cross section is provided along the groove 45 and the lower surface 42. The pushing edge 46 is fixed to the upper frame 12 via a rivet 47. By providing such a pushing edge 46, the cross-sectional shape of the groove 45 is formed with an enlarged diameter portion 45a whose diameter is increased in the horizontal direction as shown in FIG. The enlarged diameter portion 45a is a space for disposing a retaining member 49 as shown in FIG.

  The retaining member 49 is provided in the enlarged diameter portion 45 a of the upper frame 12, and includes a bolt that passes through a hole provided in the upper portion of the translucent plate 11 and a nut that is screwed into the bolt. Since the groove 45 is reduced in diameter downward from the enlarged diameter portion 45a, the retaining member 49 is locked to the reduced diameter portion. Therefore, by providing the retaining material 49 on the light transmitting plate 11, the weight of the light transmitting plate 11 can be supported via the retaining material 49.

  The lower frame 13 is made of metal, and the lower surface 51 is inclined as shown in the cross-sectional view of FIG. By making the inclination angle of the lower surface 51 substantially the same as that of the upper surface 41 of the upper frame 12, it is possible to connect them up and down in a state where they are in contact with each other without a gap. Further, the upper surface 52 is formed in a planar shape so that the lower ends of the vertical frames 14 and 15 are brought into contact with each other, and a screw hole 53 for fixing with a screw 54 is provided. A groove 55 is provided upward from the upper surface 52. The groove 55 is provided in order to fix the light-transmitting plate 11 in a state where the lower end of the light-transmitting plate 11 is inserted and held. A pushing edge 56 having a substantially L-shaped cross section is provided along the groove 55 and the upper surface 52. The pushing edge 56 is fixed to the lower frame 13 via a rivet 57. By providing such a pushing edge 56, a cross-sectional shape of the groove 55 is formed with a diameter-enlarged portion 55a whose diameter is increased in the horizontal direction as shown in FIG. 6B.

  The horizontal frame sealing material 25 is made of an elastic body such as synthetic rubber, and is interposed between the light transmitting plate 11 and the upper frame 12 or between the light transmitting plate 11 and the lower frame 13. And plays a role as a cushioning material.

  The translucent plate 11 and the upper frame 12 and the lower frame 13 are fixed by inserting the translucent plate 11 into the groove 45 of the upper frame 12 and the groove 55 of the lower frame 13, and then pressing the translucent plate 11 through the horizontal frame sealing material 25. By fitting the edges 46 and 55 into the grooves 55 and fixing them with rivets 47 and 57, the translucent plate 11, the upper frame 12 and the lower frame 13 are fixed.

  Each of the vertical frames 14 and 15 is made of metal, and is fixed to the upper frame 12 via a screw 44 and is fixed to the lower frame 13 via a screw 54. Thereby, the vertical frames 14 and 15, the upper frame 12, and the lower frame 13 are joined to each other, and the frame material is provided on the four sides of the light transmitting plate. FIG. 7 shows how the vertical frame 15 (14), the first support member 21, the second support member 22, the reinforcing plate 23, and the cover 16 are attached. The vertical frame 15 has a screw hole 60 and a groove 61, and projecting pieces 15a and 15b project substantially parallel to each other. The screw 44 and the screw 54 described above are inserted into the screw hole 60. The groove 61 is provided in order to fix the side plate of the above-described translucent plate 11 in a state where the side end is inserted and held. The vertical frame 14 (15) is provided with an eye bolt hole 69 for fixing an eye bolt 27 described later.

  The reinforcing plate 23 is made of a metal having a U-shaped cross section. The reinforcing plate 23 has a size that can be inscribed between the protruding pieces 15a and 15b. When the reinforcing plate 23 is interposed between the protruding pieces 15a and 15b, the opening side of the reinforcing plate 23 is inserted toward the vertical frame 15 (14). As a result, when viewed in a sectional view as shown in FIG. 7, a closed space is formed between the reinforcing plate 23 and the vertical frame 15 (14). When the reinforcing plate 23 is interposed between the projecting pieces 15 a and 15 b, the reinforcing plate 23 is fixed to each other via a rivet 63. A nut 65 is welded in the vicinity of the second support member 22 in the reinforcing plate 23. A hole (not shown) is also formed in advance in the reinforcing plate 23 in correspondence with the position of the hole of the welded nut 65. A bolt 66 can be screwed onto the nut 65. The reinforcing plate 23 does not need to be provided continuously from the upper part to the lower part of the vertical frames 14 and 15, and is provided intermittently at one or a plurality of places corresponding to the joining positions of the bolts 66 as shown in FIG. It may be.

  The vertical frame 14 (15) may be provided with eyebolts 27 as shown in FIG. 4, for example, in addition to the above-described configuration. The eyebolt 27 is an annular cable-like body insertion ring in plan view. The eyebolt 27 is screwed and fixed to the eyebolt hole 69 in the vertical frame 14 (15), and is fixed so that the annular portion is positioned between the protruding pieces 15a and 15b in the vertical frame 14 (15). In other words, the eyebolts 27 are provided in an arrangement that fits in the thickness from the road side to the private side in the vertical frame 14 (15).

  The vertical frame sealing material 24 is made of, for example, an elastic body such as synthetic rubber, and is interposed between the translucent plate 11 and the vertical frames 14 and 15 and plays a role as a buffer material.

  The upper reinforcing member 28 is formed of a metal face member that is fixed to the upper frame 12 via a rivet. The lower reinforcing member 29 is formed of a metal face member that is fixed to the lower frame 13 via a rivet.

  The translucent panel 4 having the above-described configuration has a depth length that fits in the space between the H-shaped steel flanges 31 and 32 that constitute the support column 3.

  Next, the configuration of the bracket 5 will be described.

  The first support member 21 has a structure in which two thin metal plates 21a and 21b are provided with a space therebetween. The thin plates 21a and 21b are joined to each other at the upper and lower ends. The first support member 21 is fixed in a state of projecting in the horizontal direction from the reinforcing plate 23 and the vertical frame 15 during assembly. Further, the cover 16 is attached to the first support member 21 via a rivet 67. Since the head of the rivet 67 is directly exposed to the outside, it may be covered with a cosmetic cap (not shown).

  The cover 16 is made of a thin metal plate and is sized to enclose the first support material 21 to which it is joined. Further, the cover 16 is configured such that the side end is bent toward the private side in a plan view. The bent cover 16 shields not only the first support member 21 and the second support member but also the vertical frames 14 and 15 from the vehicle. As a result, it is also possible to improve the view from the vehicle to the translucent panel 4 itself.

  The second support member 22 is formed by bending a metal thin plate. The second support member 22 has any configuration as long as it has a bent shape so that at least the contact surface 22a to the vertical frame 15 and the contact surface 22b to the first support member 21 are formed. Also good. The contact surface 22a and the contact surface 22b are configured to be spaced from each other so as to be substantially parallel to each other. In other words, the contact surface 22a is configured to be separated from the thin plate 21a of the first support member 21 toward the private side. Then, the contact surface 22a is fixed to the vertical frame 14 (15) while being brought into contact therewith. The contact surface 22a is provided with a hole having a diameter larger than that of the head of the rivet 63 at a position corresponding to the head of the rivet 63, and more than the foot of the bolt 66 at a position corresponding to the insertion position of the bolt 66. A large-diameter hole is provided. Further, the thin plate 21 a of the first support member 21 is brought into contact with the contact surface 22 b and fixed to each other by the rivet 68.

  It is desirable that the contact surface 22a and the contact surface 22b are provided with a distance corresponding to the thickness of the head portion of the bolt 66. The reason for this is that the head of the bolt 66 is sandwiched between the thin plate 21a of the first support member 21 and the contact surface 22a of the second support member 22 as shown in FIG. Can be fixed. That is, when the head of the bolt 66 is pressed between the thin plate 21a and the contact surface 22a, the bolt 66 is prevented from loosening with respect to the nut 65 due to vibration or wind caused by running of the vehicle. Is possible.

  Incidentally, it is desirable that the length in the height direction of the bracket 5 including the cover 16 described above is substantially the same as the length in the height direction of the frame members 12 to 15. The noise accompanying the traveling of the vehicle from the roadway can be shielded via the bracket 5, but the bracket 5 is arranged without gaps by aligning the length in the height direction of the bracket 5 in relation to the frame members 12 to 15. And leakage of noise to the outside can be prevented. The upper end of the bracket 5 including the cover 16 may be set slightly lower than the upper end of the upper frame 12, and the lower end of the bracket 5 may be set slightly higher than the lower end of the lower frame 13. The reason for this is that when the other translucent panels 4 adjacent in the vertical direction are joined, the upper surface 41 of the upper frame 12 and the lower surface 51 of the lower frame 13 may be brought into contact with each other and fixed. In such a case, when the upper end of the bracket 5 protrudes above the upper end of the upper frame 12, or when the lower end of the bracket 5 protrudes from the lower end of the lower frame 13, the bracket 5 becomes a barrier at the time of attachment. Because.

  According to the bracket 5 having the above-described configuration, it is provided on the road side (projecting piece 15b) of the vertical frames 14 and 15 provided on the left and right sides. It is provided so as to project to the adjacent column 3 side.

  Next, the actual assembly method of such a translucent sound insulation wall 1 is demonstrated. First, the column 3 is erected on the base 2 at a predetermined interval.

  Next, the work which attaches the translucent panel 4 to the support | pillar 3 via the bracket 5 is performed. First, before attaching to the support | pillar 3, the operation | work which attaches the translucent panel 4 to the bracket 5 is performed. In such a case, the work of joining the bracket 5 to the vertical frames 14 and 15 in the translucent plate 11 having the upper frame 12, the lower frame 13, and the vertical frames 14 and 15 attached to the four sides is performed. As a result, the translucent panel 4 to which the bracket 5 as shown in FIG. 4 is connected is obtained. Needless to say, the members constituting the bracket 5 may be assembled in any order during the connection.

  Next, the translucent panel 4 to which such a bracket 5 is connected is attached to the column 3. In such a case, as shown in FIG. 8, the translucent panel 4 is carried between the columns 3, and the brackets 5 formed on both side ends are applied to the columns 3 formed on both sides from the road side. Go. More specifically, as shown in FIG. 9, the first support member 21 in the bracket 5 is brought into contact with the flange 31 on the road side from the road side. As described above, the bracket 5 (the first support member 21) is provided so as to protrude from the side ends of the vertical frames 14 and 15 to the outside (the closest column 3 side). It becomes possible to make it contact | abut to the support | pillar 3 from the road side.

  Next, the flange 31 and the first support member 21 are joined to each other by a bolt 81 and a nut 82. Specifically, the thin plate 21 a in the first support member 21 is brought into contact with the flange 31, and these are joined by a bolt 81 and a nut 82. At this time, by setting the distance between the thin plate 21a and the thin plate 21b in advance corresponding to the thickness of the head of the bolt 81, the head of the bolt 81 is pressed between the thin plate 21a and the thin plate 21b. The bolt 81 can be prevented from loosening.

  Through these steps, the translucent panel 4 can be attached to the column 3 via the bracket 5. In these attachment operations, the translucent panel 4 can be attached to the column 3 from the road side. For this reason, according to this invention, it becomes possible to join the translucent panel 4 to the groove part of the support | pillar 3, without inserting from the top, and there exists a viaduct etc. above the support | pillar 3, and the space for construction cannot be ensured. Even in this case, it is possible to realize the joining of the light transmitting panel 4. Therefore, in the present invention, for example, even when highways cross each other and the other elevated road is located immediately above one road, it is possible to prevent the construction from being hindered by this.

  As a means for holding the nut 82 on the private side surface of the flange 31, the nut 82 is disposed by being sandwiched between the flanges 31 as a clip nut 83 in which a plate is processed into a U shape and the nut 82 is fixed.

  Thus, when the attachment of one translucent panel 4 to the support column 3 through the bracket 5 is completed, the translucent panel 4 in the upper or lower level is also attached to the support column 3 in the same manner. By repeating these steps, the translucent sound insulating wall 1 to which the present invention is applied is constructed.

  In the translucent sound insulation wall 1 obtained in this way, as described above, the fixing portion to the vertical frames 14 and 15 is the contact surface 22a in the second support member 22, and the fixing portion to the support column 3 is the fixing portion. It is the thin plate 21a. At this time, it can be seen that the abutment surface 22a as a fixed portion to the vertical frames 14 and 15 is located on the private side of the thin plate 21a as a fixed portion to the support column 3. Accordingly, the translucent panel 4 itself can be disposed on the private side of the surface of the flange 31 on the road side of the column 3.

  Thereby, the translucent panel 4 is not arranged in a state of projecting from the support column 3 to the road side, and the translucent panel 4 is arranged on the private side of the support column 3. For this reason, in the vicinity of the column positioned closer to the driver, the frame members 12 to 15 in the translucent panel 4 are housed between the columns 3 without projecting to the road side, and are viewed from the driver. It is possible to prevent the angle from being narrowed and to give the driver a feeling of pressure. As a result, the viewability can be improved. Further, in the vicinity of the support column 3 located on the deeper side as viewed from the driver, the groove portion of the H-shaped steel constituting the support column 3 can be prevented from entering the field of view through the translucent panel, and the viewability of the driver is lowered. Can be prevented. Moreover, since it becomes possible to arrange the translucent panel 4 on the private side from the support column 3, it is possible to prevent the translucent panel 4 from overhanging on the road side and satisfy the construction limit. be able to.

  In particular, in the translucent panel 4, the cord-like body 121 may be inserted vertically in the annular portion of the eyebolt 27 as shown in FIG. 10. The cord-like body 121 is also inserted into an eyebolt 27 provided on another translucent panel 4 positioned at an upper stage or a lower stage than the cord-like body 121. Thereby, in each translucent panel 4 connected up and down, the one cord-like body 121 is inserted through the eyebolt 27, respectively. Incidentally, this cord-like body 121 may be composed of a rope or the like, and at least its upper and lower ends are fixed.

  Thereby, each translucent panel 4 has its end fixed to the cord-like body 121 via the eyebolt 27, so that even when the translucent panel 4 deviates from the support column 3 due to an impact caused by a vehicle accident or the like, The translucent panel 4 is supported by being hooked on the cord 121 through the eyebolt 27. As a result, it is possible to prevent the translucent panel 4 from falling to the private side.

  And according to this invention, this eyebolt 27 is provided in the arrangement | positioning which fits in the thickness from the road side to a private side in the vertical frame 14 (15). For this reason, since the eyebolt 27 itself is covered with the vertical frame 14 (15) and the cover 16, the eyebolt 27 itself is not visually recognized from the outside, thereby preventing the viewability from deteriorating. It becomes.
