  One embodiment of the multipurpose soundproof wall of the present invention will be described with reference to the drawings.

  FIG. 1 is a partially omitted sectional view showing a multipurpose soundproof wall according to the present invention, FIG. 2 is a view showing mounting brackets in the multipurpose soundproof wall shown in FIG. 1, (A) is a side view, (B) ) Is a bottom view.

  In FIG. 1, 1 is a soundproof panel. The soundproof panel 1 is composed of a sound absorbing material 4 such as glass wool in a box 3 to which a surface plate 2 on which a louver 2A is formed is attached. Reference numeral 7 denotes a net as a panel structure. The net body 7 is formed by assembling vertical bars 7A and horizontal bars 7B in a lattice shape. The net body 7 may be formed by welding the vertical bars 7A and 7B with metal round bars, or may be made of a resin such as plastic, and the vertical bars 7A and 7B may be integrally formed. The material is not particularly limited as long as it is composed of 7A and horizontal rail 7B.

  If a mat 6 made of a porous material for planting growth is sandwiched between the soundproof panel 1 and the net body 7, the planting of the cocoon system will be rooted in the mat 6, and the net body 7 as a panel structure will be Etc. are entangled, and the soundproof wall can be easily greened. The mat 6 may be attached to the mesh body 7 in advance at a position where the vertical beam 7A, the horizontal beam 7B, or the vertical beam 7A and the horizontal beam 7B intersect with a line or the like. Even if the mat 6 is attached to the soundproof panel 1, since the mat 6 is porous, there is no possibility that the soundproofing effect is lowered.

  Reference numeral 8 denotes a mounting bracket, which is preferably rich in elastic force. The mounting bracket 8 has a function of mounting the net body 7 as a panel structure to the surface plate 2 of the soundproof panel 1 with one touch. As shown in FIGS. 2A and 2B, the mounting bracket 8 is formed by bending a plate material into a V shape to form an upper piece 8A and a lower piece 8B. The lower piece 8B may be the same length as the upper piece 8A or shorter than the upper piece 8A. An upper hook 8C is formed at the base end portion of the upper piece 8A by bending the upper piece 8A upward. A lower hook 8D is formed at the base end portion of the lower piece 8B by bending the lower piece 8B downward. The horizontal rail 7 </ b> B of the net body 7 is locked to the V-shaped portion of the mounting bracket 8. The upper hook 8C is locked to the sound absorbing material side edge (P1) of one louver 2A1, and the lower hook 8D is the sound absorbing material side edge (P2) of the other louver 2A2 formed below the one louver 2A1. ).

  As shown in FIG. 2C, a clamping portion 8F having a width smaller than the plate thickness of the louver 2A may be formed on at least one of the upper hook 8C and the lower hook 8D of the mounting bracket 8. That is, when the mounting bracket 8 is attached to the louver 2A, the clamping portion 8F is expanded against the elastic force of the mounting bracket 8 and is locked to the louver 2A, so that the mounting bracket 8 is biased in the reduction direction. The rattling of the mounting bracket 8 when mounted on the louver 2A can be further reduced.

  In order to attach the mat 6 and the net body 7 to the soundproof panel 1 with the mounting bracket 8, the following is performed.

  As shown in FIG. 1, the mat 6 is applied to the soundproof panel 1 so as to contact the surface plate 2. In this state, the fitting 6 is inserted between the louvers 2 </ b> A through the mat 6 from the outside of the horizontal bar 7 </ b> B of the net body 7. At this time, the mounting bracket 8 is inserted so that the upper hook 8C and the lower hook 8D enter between the one louver 2A1 and the other louver 2A2. When the mounting bracket 8 is inserted between the louvers 2A, the mounting bracket 8 is compressed by the elastic force as shown by the dotted line in FIG. The mat 6 is previously formed with slits (not shown) through which the upper piece 8A and the lower piece 8B of the mounting bracket 8 pass. When the mounting bracket 8 is further inserted against the elastic force of the sound absorbing material 4, the upper hook 8C of the upper piece 8A is locked to the sound absorbing material side edge (P1) of one louver 2A1, and the lower part of the lower piece 8B. The hook 8D is engaged with the sound absorbing material side edge (P2) of the other louver 2A2. After locking, the mounting bracket 8 returns to the original state indicated by the solid line in FIG.

  Thus, the mounting bracket 8 has its upper hook 8C and lower hook 8D locked to the sound absorbing material side edges (P1) and (P2) of the louver 2A, respectively. As a result, a pulling force acts on the mounting bracket 8. There is no way out. Moreover, since the upper hook 8C and the lower hook 8D are pushed from the inside to the outside by the elastic force of the sound absorbing material 4, the mounting bracket 8 does not rattle inward and outward. The net 7 is fixedly attached to the surface plate 2 of the soundproof panel 1 in the vertical direction because the horizontal rail 7 </ b> B is locked by the mounting bracket 8. Movement of the mat 6 in the left-right direction does not occur because the mat 6 is connected in the left-right direction. The movement of the mat 6 and the net body 7 can be more reliably prevented by increasing the number of mounting brackets 8 attached.

  In this way, the mat 6 and the net body 7 can be securely attached to the soundproof panel 1 with a single touch by simply inserting the mounting bracket 8 between the louvers 2A.

  5A and 5B show another mounting bracket 9. The mounting bracket 9 is formed by bending a plate material into a V shape to form an upper piece 9A and a shorter lower piece 9B. An upper hook 9C is formed at the base end portion of the upper piece 9A by bending the upper piece 9A upward. A contact portion 9D is formed at the base end portion of the lower piece 9B by bending the lower piece 9B upward. The horizontal rail 7 </ b> B of the net body 7 is locked to the V-shaped portion of the mounting bracket 9. The upper hook 9C is locked to the sound absorbing material side edge (P) of one louver 2A1, and the contact portion 9D is the upper surface of the other louver 2A2 formed below the one louver 2A1 (see FIG. 3). Or it contacts the lower surface (see FIG. 4).

  As with the mounting bracket 8 described above, the mounting bracket 9 is preferably rich in elastic force, and if a holding portion as shown in FIG. 2C for holding the louver 2A is formed on the upper hook 9C, The rattling of the mounting bracket 9 when the mounting bracket 9 is mounted on the louver 2A can be further reduced.

  In order to attach the mat 6 and the net body 7 to the soundproof panel 1 with the mounting bracket 9, the following is performed.

  One attachment method is as follows. As shown in FIG. 3, the mat 6 is applied to the soundproof panel 1 so as to abut on the surface plate 2. In this state, the fitting 6 is inserted between the louvers 2A through the mat 6 from the outside of the horizontal rail 7B of the net body 7. At this time, the mounting bracket 9 is inserted so that the upper hook 9C and the contact portion 9D enter between the one louver 2A1 and the other louver 2A2. The mounting bracket 9 is compressed by its elastic force as shown by the dotted line in FIG. The mat 6 is previously formed with slits (not shown) through which the upper piece 9A and the lower piece 9B of the mounting bracket 9 pass. When the mounting bracket 9 is further inserted against the elastic force of the sound absorbing material 4, the upper hook 9C of the upper piece 9A is locked to the sound absorbing material side edge (P) of one louver 2A1, and the lower piece 9B is contacted. The contact portion 9D contacts the upper surface of the other louver 2A2. After the upper hook 9C is locked, the upper piece 9A returns to the original state indicated by the solid line in FIG.

  Thus, the mounting bracket 9 does not come out even when a pulling force acts on the mounting bracket 9 as a result of the upper hook 9C being locked to the sound absorbing material side edge (P) of the louver 2A. In addition, since the upper hook 9C is pushed from the inside to the outside by the elastic force of the sound absorbing material 4, the mounting bracket 9 does not rattle inward and outward. Further, since the abutting portion 9D of the lower piece 9B is abutted on the upper surface of the other louver 2A2, the mounting bracket 9 does not rattle in the vertical direction. The mat 6 and the mesh body 7 are fixedly attached to the surface plate 2 of the soundproof panel 1 in the vertical direction because the horizontal rail 7B of the mesh body 7 is locked by the mounting bracket 9. The movement of the mat 6 and the net body 7 can be more reliably prevented by increasing the number of mounting brackets 9 attached.

  Another method for attaching the mat 6 and the net 7 is as follows. As shown in FIG. 4, the louver 2A is inserted between the upper piece 9A and the lower piece 9B. In this state, the fitting 6 is inserted between the louvers 2A through the mat 6 from the outside of the horizontal rail 7B of the net body 7. At this time, the mounting bracket 9 is inserted so that the louver 2A is sandwiched between the upper hook 9C and the contact portion 9D. Accordingly, the upper hook 9C is locked to the sound absorbing material side edge (P1) of one louver 2A1, and the abutting portion 9D of the lower piece 9B of the mounting bracket 9 abuts the lower surface of the other louver 2A2. The mounting bracket 9 can be securely attached to the surface plate 2 with one touch. Other effects are almost the same as the case of insertion as shown in FIG.

  According to the mounting bracket 8 shown in FIG. 2, the mounting bracket 8 cannot be attached to the surface plate 2 unless the mounting bracket 8 is always inserted between the one louver 2A1 and the other louver 2A2. According to this, it is possible to attach the mounting bracket 9 to the front plate 2 in any state between the louvers 2A.

  FIGS. 7A and 7B show another mounting bracket 10. The mounting bracket 10 is formed by bending a plate material into a U shape to form an upper piece 10A and a lower piece 10B having the same length. As shown in FIG. 6, the interval (L1) between the upper piece 10A and the lower piece 10B of the mounting bracket 10 is substantially equal to the louver interval. An upper hook 10C is formed at the base end portion of the upper piece 10A by bending the upper piece 10A downward. A lower hook 10D is formed at the base end portion of the lower piece 10B by bending the lower piece 10B downward. The horizontal rail 7 </ b> B of the net body 7 is locked to the lower corner portion of the mounting bracket 10. As shown in FIG. 6, the upper hook 10C is locked to the sound absorbing material side edge (P1) of one louver 2A1, and the lower hook 10B is the other louver 2A2 formed below the one louver 2A1. Lock to the sound absorbing material side edge (P2).

  The mounting bracket 10 is preferably rich in elastic force like the mounting brackets 8 and 9 described above, and the louver 2A is sandwiched between the upper hook 10C and the lower hook 10D as shown in FIG. 2C. If the portion is formed, rattling of the mounting bracket 10 when the mounting bracket 10 is mounted on the louver 2A can be further reduced.

  In order to attach the mat 6 and the net body 7 to the soundproof panel 1 with the mounting bracket 10, the following is performed.

  As shown in FIG. 6, the mat 6 is applied to the soundproof panel 1 so as to abut on the surface plate 2. In this state, the mounting bracket 10 is inserted between the louvers 2A through the mat 6 from the outside of the horizontal rail 7B of the net body 7. At this time, the mounting bracket 10 is inserted so that the louver 2A is sandwiched between the upper piece 10A and the lower piece 10B. In addition, if the mounting bracket is tilted outward and inserted toward the upper side, it can be locked to the louver 2A without being elastically biased. The mat 6 is previously formed with slits (not shown) through which the upper piece 10A and the lower piece 10B of the mounting bracket 10 pass. When the mounting bracket 10 is further inserted against the elastic force of the sound absorbing material 4, the upper hook 10C of the upper piece 10A is locked to the sound absorbing material side edge (P1) of one louver 2A1, and the lower portion of the lower piece 10B. The hook 10D is engaged with the sound absorbing material side edge (P2) of the other louver 2A2. As a result, the mat 6 and the net 7 can be securely attached to the surface plate 2 of the soundproof panel 1 by the mounting bracket 10 with one touch.

  As a result of the upper hook 10C and the lower hook 10D being locked to the sound absorbing material side edges (P1) and (P2) of the louver 2A, the mounting bracket 10 will not come out even if a pulling force acts on the mounting bracket 10. Absent. Moreover, since the upper hook 10C and the lower hook 10D are pushed from the inside to the outside by the elastic force of the sound absorbing material 4, the mounting bracket 8 does not rattle inward and outward. The mat 6 and the mesh body 7 are fixedly attached to the surface plate 2 of the soundproof panel 1 in the vertical direction because the horizontal rail 7B of the mesh body 7 is locked by the mounting bracket 8. The movement of the mat 6 in the left-right direction does not occur because the mat 6 is connected in the left-right direction. The movement of the mat 6 and the net body 7 can be more reliably prevented by increasing the number of mounting brackets 10 attached.

  Since the mounting bracket 10 is formed in a U shape, an interval (L1) substantially equal to the interval between the louvers is formed between the upper piece 10A and the lower piece 10B. Even if the positional relationship with the crosspiece 7B deviates in the vertical direction, it can be reliably locked. Therefore, even when the position of the louver 2A of the surface plate 2 cannot be visually recognized by the mat 6 or the like, the net body 7 can be reliably attached to the surface plate 2.

  FIGS. 10A and 10B show another mounting bracket 11. Note that the vertical beam 7A of the net 7 after FIG. 8 is omitted, and only the horizontal beam 7B is shown. This mounting bracket 11 is effective when the net body 7 is mounted away from the soundproof panel 1. The mounting bracket 11 is formed by forming a lower piece 11A by bending a part of the base end portion of the plate material downward. A pair of upper hooks 11 </ b> B are formed at the base end portion of the mounting bracket 11 by bending the plate material downward. A lower hook 11C is formed at the tip of the lower piece 11A by bending the lower piece 11A upward. A net hook 11D is formed at the front end of the plate by bending it upward. The crosspiece 7B of the net body 7 is locked to the net hook 11D of the mounting bracket 11. As shown in FIG. 8, the upper hook 11A is locked to the sound absorbing material side edge (P1) of the louver 2A, and the lower hook 11C is locked to the outer edge (P3) of the louver 2A.

  The mounting bracket 11 is preferably rich in elasticity like the mounting brackets 8, 9 and 10 described above, and the louver 2A is sandwiched between the upper hook 11B and the lower hook 11C, as shown in FIG. If the clamping part is formed, rattling of the mounting bracket 11 when the mounting bracket 11 is mounted on the louver 2A can be further reduced. In addition, if the clamping part is formed also in the hook 11D for net | network bodies, the crosspiece 7B of the mat 6 can be attached more reliably.

  In order to attach the mat 6 and the net body 7 to the soundproof panel 1 with the mounting bracket 11, the following is performed.

  As shown in FIG. 9A, the mounting bracket 11 is inserted into the mat 6 so that the mesh hook 11D of the mounting bracket 11 protrudes to the outside of the mat 6. The mat 6 is previously formed with a slit (not shown) through which the mounting bracket 11 passes. Next, in this state, as shown in FIG. 9B, the mounting bracket 11 is inserted between the louvers 2A. At this time, the mounting bracket 11 is inserted so that the louver 2A is sandwiched between the upper hook 11B and the lower hook 11C. Thus, the lower hook 11C of the mounting bracket 11 is locked to the outer edge (P3) of the louver 2A, and when further inserted, the upper hook 11B of the mounting bracket 11 absorbs the sound of the louver 2A as shown in FIG. Lock to the material side edge (P1). As a result, the mat 6 and the net 7 can be reliably attached to the surface plate 2 of the soundproof panel 1 by the attachment fitting 11 with one touch.

  Thus, the mounting bracket 11 has its upper hook 11B locked to the sound absorbing material side edge (P1) of the louver 2A, and the lower hook 11C locked to the outside (P3) of the louver 2A. Even if a pulling force is applied to this, it will not come out. Moreover, both edges (P1) and (P3) of the louver 2A are sandwiched between the upper hook 11B and the lower hook 11C, and the upper hook 11B is pushed outward from the inside by the elastic force of the sound absorbing material 4. The metal fitting 11 does not rattle inward and outward. The net 7 is fixedly attached to the surface plate 2 of the soundproof panel 1 in the vertical direction because the horizontal rail 7 </ b> B is locked by the mounting bracket 11. The movement of the mat 6 and the net body 7 can be further reliably prevented by increasing the number of mounting brackets 11 attached.

  Moreover, since the mat 6 can be mounted away from the soundproof panel 1, the wet mat 6 does not come into contact with the soundproof panel 1, thereby reducing rusting of the surface plate 2. In addition, since a space is formed between the soundproof panel 1 and the mat 6, the air permeability is excellent, and the heat of the soundproof panel 1 heated by solar heat is not easily transmitted directly to the mat 6. Can reduce the damage.

  FIGS. 13A and 13B show another mounting bracket 12. Similar to the mounting bracket 11, the mounting bracket 12 is effective when the net body 7 is mounted away from the soundproof panel 1. The mounting bracket 12 is formed by forming a lower piece 12A by bending a part of a base end portion of a plate material downward. A pair of upper hooks 12 </ b> B are formed at the base end portion of the mounting bracket 12 by bending the plate material downward. At the tip of the lower piece 12A, a contact portion 12C is formed by bending the lower piece 12A downward. A net hook 12D is formed at the front end of the plate by bending it upward. The crosspiece 7B of the net body 7 is locked to the net hook 12D of the mounting bracket 12. As shown in FIG. 11, the upper hook 12A is locked to the sound absorbing material side edge (P1) of the louver 2A, and the lower hook 12C is in contact with the upper surface of the louver 2A.

  The mounting bracket 12 is preferably rich in elastic force similarly to the mounting brackets 8, 9, 10 and 11 described above, and a clamping portion as shown in FIG. 2C for clamping the louver 2A to the upper hook 12B. If formed, rattling of the mounting bracket 12 when the mounting bracket 12 is mounted on the louver 2A can be further reduced. In addition, if the clamping part is also formed in the mesh hook 12D, the cross rail 7B of the mat 6 can be more reliably attached.

  In order to attach the mat 6 and the net body 7 to the soundproof panel 1 with the mounting bracket 12, the following is performed.

  As shown in FIG. 12A, the mounting bracket 12 is inserted into the mat 6 so that the mesh hook 12D of the mounting bracket 12 protrudes to the outside of the mat 6. The mat 6 is previously formed with a slit (not shown) through which the mounting bracket 12 passes. Next, in this state, as shown in FIG. 12B, the mounting bracket 12 is inserted between the louvers 2A. At this time, the mounting bracket 12 is inserted so that the upper hook 12B and the contact portion 12C enter between the louvers 2A. Thus, as shown in FIG. 11, the upper hook 12B of the mounting bracket 12 is locked to the sound absorbing material side edge (P), and the contact portion 12C is in contact with the upper surface of the louver 2A.

  Thus, the mounting bracket 12 has its upper hook 12B locked to the sound absorbing material side edge (P) of the louver 2A, and the contact portion 12C contacts the upper surface of the louver 2A. Does not come out even if the sway acts, and the mounting bracket 12 does not rotate downward. As a result, the mat 6 and the net 7 can be securely attached to the soundproof panel 1 by the mounting bracket 12 with one touch. Moreover, the upper hook 12B is pushed from the inside to the outside by the elastic force of the sound absorbing material 4, so that the mounting bracket 12 does not rattle inward and outward. The net 7 is fixedly attached to the surface plate 2 of the soundproof panel 1 in the vertical direction because the horizontal rail 7B is locked by the mounting bracket 12. The movement of the mat 6 and the net body 7 can be further reliably prevented by increasing the number of mounting brackets 12 attached.

  According to the mounting bracket 12, the mat 6 can be mounted away from the soundproof panel 1, so that the same effect as in the mounting bracket 11 shown in FIG. 8 can be obtained.

  The above is a case where a planting mat as a planting means is attached to the panel structure to greenen the soundproof wall. In addition to the planting mat 6, some display means such as advertising means or road signs, Solar power generation means such as a solar panel can be attached. In these cases, it goes without saying that it is necessary to prevent the soundproof function from being lowered by attaching the panel structure to the soundproof panel 1.

  According to the present invention, a panel structure such as a mesh body can be easily and reliably applied from the front side of the surface plate without any processing on the surface plate of the soundproof panel by simply inserting the mounting bracket between the louvers. Can be attached to.
