Description

  The present invention relates to a structure for attaching a soundproof panel to a structure such as a column to constitute a soundproof wall, and a method for attaching a soundproof panel to a structure.

  For example, equipment used for cogeneration systems, outdoor heat source equipment such as coolers (cooling towers), chillers, etc., which require exhaust by moving air due to the thermal draft effect (hereinafter collectively referred to as outdoor units) For example, as shown in FIG. 9, pillars 111 made of H-shaped steel are arranged at regular intervals, and a horizontally-long soundproof panel 105 is installed between these pillars 111 as soundproof walls for shielding noise generated from roads and roads. There is a soundproof wall 101 that is configured to be stacked in a plurality of stages (see Patent Document 1).

  In such a soundproof wall, the structure for mounting the soundproof panel is required to have good work efficiency of attachment, excellent appearance without impairing the appearance, etc., in order to meet such a request, In Patent Document 1, as shown in FIG. 10, one end 115 a of the clasp 115 is inserted into the hollow portion 105 a of the panel 105, and the other end 115 b is fastened to the column 111 with a bolt 116. A panel mounting structure is disclosed (hereinafter referred to as conventional structure 1).

  According to the conventional structure 1 shown in FIG. 10 described above, the support 111 as a base material can be made invisible from the outside, and the panel 105 does not need to be perforated so that the appearance is good. The advantage that the panel 105 can be easily attached to the column 111 is obtained.

  Further, as shown in FIG. 11, a screw hole is provided by drilling a bolt insertion hole in one of the flanges 211a and 211b of the column 211 made of H-shaped steel and welding a nut 217. The ends of the soundproof panels 205 and 205 are inserted between the flanges 211a and 211b, the bolts 216 are screwed into the screw holes of the flange 211a from the outside, and the ends of the soundproof panels 205 and 205 are pressed and fixed at the tips. There is also a structure that does this (hereinafter referred to as the conventional structure 2).

  Further, in place of fixing the soundproof panel 205 with the bolt 216 in the conventional structure 2 shown in FIG. 11, a wedge-shaped cross section is provided between one flange 211a of the column 211 and the soundproof panel 205 as shown in FIG. There is also a structure in which a mounting bracket 218 having a shape is press-fitted and one piece of the mounting bracket 218 is fixed to the panel 205 with a tapping screw 219 (hereinafter referred to as a conventional structure 3).

  Furthermore, as shown in FIG. 13, for example, hook bolts 220 are welded and fixed to the outer surface of one flange 211b of the support column 211 at a predetermined interval, and the end of the soundproof panel 205 is connected to the flange 211b of the support column 211. A cover plate 221 is attached from the outside in a state of being arranged so as to overlap from the outside, and the soundproof panel 205 is attached to the column 211 by inserting the hook bolt 220 into the cover plate 221 and fastening with a nut. There is also a structure that is fixed to (hereinafter referred to as conventional structure 4).

JP-A-5-132912

  According to the conventional structure 2 shown in FIG. 11 and the conventional structure 3 shown in FIG. 12, the mounting work can be performed with the soundproof panel 205 held between the flanges 211a and 211b of the support column 211. Although it is easy, there is a problem that the column 211 is exposed to the outside and the appearance is inferior.

  For example, when constructing a high soundproof wall, it is necessary to use a large column 211 corresponding to this, and the distance between the one flange 211a and the soundproof panel 205 increases accordingly. In this case, in the conventional structure 2 shown in FIG. 11, it is conceivable to fix the bolt 216 in place of a long one, but sufficient strength cannot be secured, while in the conventional structure 3 shown in FIG. Depending on the mounting hardware 218, it is difficult to fix the soundproof panel 205. Therefore, for example, as shown in FIG. 14, the angle 222 is welded to the web 211c of the support column 211, and one piece of the angle 222 is used in place of the flange 211a of the support column 211. It is possible to fix the soundproof panel 205 with the mounting hardware 218 in the structure 3 (or the bolt 216 and the nut 217 in the conventional structure 2 shown in FIG. 11), but according to this, the angle 222 is formed on the column 211. Since welding is performed, there is a problem that the work on the support column 211 increases, and that the welding operation of the angle 222 requires a relatively long time.

  Further, in the case of the conventional structure 2 shown in FIG. 11, it is necessary to perforate the flange 211 a and weld the nut 217 to the support column 211, which increases the processing. In addition, when hot dip galvanizing is applied to the column 211 as a rust-proofing process, the screw hole of the nut 217 is blocked by plating, or the screw groove is crushed by plating until the screw hole is not closed. There is also a problem that needs to be performed.

  Further, according to the conventional structure 4 shown in FIG. 13, the column 211 is not exposed to the outside, and even if a large column 211 is used, the mounting structure of the soundproof panel 205 is not affected. The hook bolt 220 needs to be welded and is often processed, and the hook bolt 220 needs to be disposed at a relatively short interval, and welding requires a little work. Also in this case, there is a problem that the thread of the hook bolt 220 is crushed by plating. Further, as described above, although the column 211 is not exposed, the tip and the nut of the hook bolt 220 are exposed, so that the appearance is inferior.

  On the other hand, according to the conventional structure 1 shown in FIG. 10, it is considered that there is generally no problem as in the conventional structure 2 to the conventional structure 4 shown in FIG. Since it has the structure fixed using 105a, it cannot respond to the sound-insulation panel which does not have a hollow part. In the case of a soundproof panel having no hollow portion, for example, a metal fitting that can function in the same manner as the hollow portion 105a is attached to one side surface (fixed side surface) of the soundproof panel, and the soundproof panel is fixed using this metal fitting. However, according to this, the number of parts and the number of processes increase.

  More importantly, when connecting columns made of H-shaped steel in the length direction in order to build a high soundproof wall, a splice plate (attachment plate) is attached to this connecting part and fastened with bolts. These splice plates and bolts protrude from the outer surface of the column with a step, but in either case of the conventional structure 1 shown in FIG. 10 to the conventional structure 4 shown in FIG. Since the soundproof panel is fixed so as to be in contact with the support column, there is a problem in that the soundproof panel cannot be fixed due to a protruding portion made of a splice plate or bolt at the connecting portion.

  The present invention has been devised in view of such problems, has an excellent appearance without losing the appearance, has a simple structure, and can easily perform the processing of the columns and the mounting of the soundproof panel, It is an object to provide a soundproof panel mounting structure that is not affected by fluctuations in the structure of the soundproof panel and the dimensions of the column, and that can also correspond to the protruding portion of the structure such as the connecting portion of the column. To do.

  It is another object of the present invention to provide a soundproof panel mounting method capable of efficiently and easily mounting a soundproof panel.

The soundproof panel mounting structure according to the present invention is made to achieve the above object, and the first gist thereof is as follows.
A structure for attaching a soundproof panel for constructing a soundproof wall to a structure,
A support member having at least one mounting surface is disposed on the structure so as to extend in a horizontal direction;
On the mounting surface of the support member, at least one rail member having a U-shaped cross section is supported and fixed in a state of being spaced from the structure.
A soundproof panel is fitted in the rail member.

  In the present invention, the term “soundproof panel” means any plate-like body that has sound insulation and / or sound absorption and can suppress the propagation of sound. The “structure” includes anything that can support a soundproof panel. For example, in addition to an upright column, a pillar, a beam, a girder, etc. (a wall panel is attached). Included) and structural walls. For this reason, the term “soundproof wall” implies that a soundproof panel is installed on a wall or the like in addition to a soundproof panel constructed on a column.

In addition, the second gist of the soundproof panel mounting structure according to the present invention is that in the first gist,
The support member is configured by joining a rectangular plate material to a structure in a vertical state.

Further, the third gist of the soundproof panel mounting structure according to the present invention is that in the first or second gist,
The rail member is configured to have a U-shaped cross section by opposingly arranging L-shaped members, and the L-shaped member can be slid along the extending direction of the support member in a temporarily fixed state. It is supported so that it becomes.

Moreover, the mounting method of the soundproof panel according to the present invention is as follows.
A method of attaching a soundproof panel for constructing a soundproof wall to a structure,
A support member having at least one attachment surface is disposed on the structure so as to extend in the horizontal direction, and includes the following steps a) and b).
a) At least one rail member having a U-shaped cross section is supported and fixed on the mounting surface of the support member with a space between the rail member and the structure. b) The soundproof panel is fitted and fixed to the rail member.

  According to the soundproof panel mounting structure according to the present invention, the soundproof panel is attached with a space between the structure and the support member extending in the horizontal direction, so that the structure is exposed to the outside. Therefore, the appearance of the structure is not impaired. In addition, since the soundproof panel is held by the rail member having a U-shaped cross section, the soundproof panel can be attached without using bolts or nuts, and the appearance can be maintained well.

  Further, by using a rail member having a U-shaped cross section, the structure is simplified, and the panel is not fixed directly to the structure, so that the processing of the structure is reduced.

  In addition, by holding the soundproof panel on the rail member having a U-shaped cross section, it is easy to attach the soundproof panel and the work efficiency is good. Further, there is no restriction such as a hollow structure of the soundproof panel, and it is possible to deal with soundproof panels having other structures.

  In addition, since the soundproof panel is attached with a space between the structure and the structure, the dimensions of the structure are not affected at all. Furthermore, for example, when the structure is configured by connecting H-shaped steel, the structure may have a protruding portion, such as a splice plate or bolt protruding at the connecting portion. The soundproof panel can be attached without interfering with such a protruding portion.

  Moreover, according to the mounting structure of the soundproof panel according to the second aspect of the present invention, since the support member is configured by joining the structure body in a state where the rectangular plate material is vertical, the mounting structure is simple. It has become a thing. In other words, the joining of the rectangular plate materials is relatively simple, such as easy alignment as compared with conventional welding of hook bolts and the like. Moreover, the arrangement | positioning space | interval of a supporting member can also be taken comparatively large. Therefore, it is possible to facilitate the processing of the structure as compared with the prior art and reduce the number of processing points. Further, if the rail member is fixed to the support member with, for example, bolts and nuts, it is only necessary to make a bolt insertion hole in the support member, and it is not necessary to provide a screw or the like. Etc., no problems occur.

Moreover, according to the mounting structure of the soundproof panel according to the third aspect of the present invention, the rail member is configured to have a U-shaped cross section by disposing an L-shaped member facing each other. Since the members are supported so as to be slidable along the extending direction of the support member in the temporarily fixed state, alignment when attaching these members to the structure can be easily performed. At this time, since the position of the soundproof panel with respect to the structure is defined by the position of the L-shaped member with respect to the structure, the soundproof panel can be easily aligned at the same time. Moreover, since the width | variety of a rail member can be easily adjusted by sliding these cross-section L-shaped members, it can respond easily when using the sound-insulation panel from which thickness differs.
Further, according to the mounting method of the soundproof panel according to the present invention, the support member having at least one mounting surface is disposed in the structure so as to extend in the horizontal direction.
a) a step of supporting and fixing at least one rail member having a U-shaped cross section on the mounting surface of the support member in a state of being spaced from the structure; and b) fitting and fixing the soundproof panel to the rail member. Since it has a process, it is possible to efficiently and easily attach the soundproof panel. That is, when performing the mounting operation, the soundproof panel can be easily guided to the mounting position by fitting the soundproof panel into the rail member having a U-shaped cross section. Further, the mounting work can be performed in a state where the soundproof panel is held at the mounting position, and the operator does not need to hold the soundproof panel directly at the mounting position. Therefore, it is easy to attach the soundproof panel and the work efficiency is good.

A gap having a distance equal to the thickness of the bracket 6 is formed between the protruding portions. The gap is sealed with a sealing material 8 made of a caulking material, rubber packing, or the like.

  The mounting structure of the soundproof panel 5 shown in this embodiment is applied to the construction of the soundproof wall 1 for suppressing noise generated from an outdoor unit installed in an outdoor part of a building. For example, in FIG. 2, an outdoor unit (not shown) is installed in a direction opposite to the side of the support 11 where the soundproof panel 5 is attached, and noise generated from the outdoor unit is indicated by an arrow X in the figure. As shown in FIG. 4, the noise propagates in the direction from the support 11 to the soundproof panel 5, and this noise is shielded by the soundproof panel 5.

(Soundproof panel mounting process)
Next, the mounting process of the soundproof panel will be described. The mounting process of the soundproof panel of the present embodiment basically includes the following processes a) and b).
a) A rail member is supported and fixed on the mounting surfaces 6R and 6L of the bracket 6 with a gap between the rail 11 and the support column 11. b) The soundproof panel 5 is fitted and fixed to the rail member. Each step of b) will be described in detail.

  a) First, as shown in FIG. 4, the first elongate members 701 and 701 are superposed and fixed on both surfaces of the bracket 6, that is, the attachment surfaces 6R and 6L on both sides, respectively. At this time, as described above, the bolt insertion hole 601a of the bracket 6 is a long hole extending horizontally in the front-rear direction, that is, along the extending direction of the bracket 6, and accordingly, the first elongated material 701, In the temporarily fixed state, 701 is supported so as to be slidable horizontally in the front-rear direction, that is, along the extending direction of the bracket 6, so that the first long material 701 is temporarily fixed with the bolt 703a and the nut 704a. After 701 is slid horizontally in the front-rear direction, that is, along the extending direction of the bracket 6, the position is adjusted, and then final tightening is performed. The gap formed between the first long materials 701 and 701 is filled with the sealing material 8 and sealed at an appropriate stage thereafter.

  Next, the second long materials 702 and 702 are superposed and fixed on the surfaces of the one pieces 701a and 701a fixed to the bracket 6 of the first long materials 701 and 701, respectively. At this time, as described above, the bolt insertion holes 702c and 702c of the second elongated members 702 and 702 are elongated holes extending horizontally in the front-rear direction, that is, along the extending direction of the bracket 6, and therefore Accordingly, the second long members 702 and 702 are supported so as to be slidable horizontally in the front-rear direction, that is, along the extending direction of the bracket 6 in the temporarily fixed state. The second elongate members 702 and 702 are aligned by sliding horizontally in the front-rear direction, that is, along the extending direction of the bracket 6, and then tightened.

  b) Thereafter, as shown in FIG. 2, in the groove-shaped portion of the rail member having a U-shaped cross section formed by the first long material 701, 701 and the second long material 702, 702, The soundproof panels 5 and 5 are arranged so that the side ends of the soundproof panels 5 and 5 are inserted, and the soundproof panels 5 are sequentially dropped from the lower stage, and the extension pieces 504b outside the soundproof panel 5 are attached to the first long material 701. Secure with rivets. At this time, as shown in FIG. 1, the protrusion 506 provided on the upper end surface of the lower soundproof panel 5 is fitted with the recess 507 provided on the lower end surface of the upper soundproof panel 5. The soundproof panels 5 are arranged and attached so as to be stacked sequentially from the bottom to the top. A top panel is attached to the uppermost soundproof panel 5 (not shown). Further, at the end or corner portion of the soundproof wall 1, the rail member is fixed only to one of the mounting surfaces 6R and 6L on both sides of the bracket 6 disposed on the support column 11 located in the portion. The soundproof panel 5 is attached, and the other attachment surface is covered with a covering member. In addition, in the pillar 11 at the corner portion, a bracket is disposed on the web in addition to the flange. A bracket is provided on each of the two side surfaces to fix the rail member, and the soundproof panel 5 is attached (not shown). The soundproof wall 1 is completed through the above processes.

(Function)
In the mounting structure of the soundproof panel 5, brackets 6, which are support members having mounting surfaces 6 R, 6 L on both sides, are disposed on the column 11, which is a structure, so as to extend in the horizontal direction. A rail member having a U-shaped cross section is supported and fixed on the mounting surfaces 6R and 6L on both sides with a space between the rail 11 and the support 11, and the soundproof panel 5 is fitted into the rail, and the support 11 is outside. It is structured not to be exposed. For this reason, the appearance of the soundproof wall 1 is not impaired by the support 11. In addition, since the soundproof panel 5 is fitted and held on a rail member having a U-shaped cross section and is fixed with a rivet, bolts and nuts are not exposed to the outside, and the appearance is clean. The aesthetics are good.

  Moreover, the structure is also simplified by using a rail member having a U-shaped cross section. That is, the soundproof panel 5 is held by the rail member extending in the height direction, so that the mounting structure itself is compared to the case where each soundproof panel is directly attached to the structure with a bolt or the like as in the prior art. Is simplified. In addition, since the soundproof panel 5 is not directly fixed to the support column 11, it is not necessary to perform a relatively troublesome process such as welding of a nut to the support column 11, drilling of a bolt insertion hole, or welding of an angle or the like.

  In addition, since the soundproof panel 5 is inserted into the U-shaped rail member, the soundproof panel 5 is guided to the mounting position by the rail member when performing the mounting operation. Installation work of the soundproof panel 5 is facilitated. Further, since the soundproof panel 5 is structured to be held at the mounting position by the rail member, it is not necessary for the operator to directly hold the soundproof panel 5 at the mounting position during the mounting work, and the mounting work is more likely to be performed. Easy to do. Moreover, since the structure of the soundproof panel 5 may be anything that can be fitted into the rail member, there is no restriction such as being hollow, and soundproof panels having other structures can be accommodated.

  In addition, since the soundproof panel 5 is attached with a space between the column 11 and the column 11, the size of the column 11 is not affected at all. That is, for example, when the flange interval between the columns becomes large as in the conventional case, there is no need to add a member that replaces the flange.

  Furthermore, as shown in FIGS. 1 and 3, the soundproof panel 5 can be attached to the connecting portion 11J of the column 11 without interfering with the protruding portion formed by the splice plate 11d and the bolt 11e. In the connecting portion 11J of the support column 11, a protruding portion is formed by the splice plate 11d and a large number of bolts 11e. However, the soundproof panel 5 is attached at an interval without contacting the support column 11, The protruding portion formed by the splice plate 11d and the bolt 11e does not become an obstacle to the mounting of the soundproof panel 5.

  In the present embodiment, as shown in FIG. 1, a notch 701 e that is slightly longer than the connecting portion 11 </ b> J of the column 11 is provided on the inner end edge (end column on the column 11) of the first long material 701. Thus, the first elongate member 701 is configured not to interfere with the splice plate 11d of the connecting portion 11J. For example, the first elongate member 701 is further spaced from the support column 11. Such a cut-out portion can be made unnecessary.

  Furthermore, in the mounting structure of the soundproof panel 5, the bracket 6 as a support member is configured by joining a plate-like member made of a square steel plate to the column 11 in a vertical state. The mounting structure is simple. In other words, the welding of the rectangular plate material is relatively simple as compared with the conventional welding of a hook bolt or the like, and the operation is relatively simple. In addition, with the use of the rail member, the interval between the brackets 6 can be made relatively large. Therefore, it is possible to facilitate the processing of the support column 11 and reduce the number of processing points as compared with the prior art. Further, the bracket 6 is only provided with bolt insertion holes 601a and 601b, and is not provided with screws or the like. Therefore, even if the support 11 is subjected to hot dip galvanization or the like, no trouble occurs.

  Further, in the mounting structure of the soundproof panel 5, the rail member is configured to have a U-shaped cross section by disposing a first long material 701 having a L-shaped cross section and a second long material 702 facing each other. The bolt insertion holes 601a, 601b, 702c for fastening and fixing the first and second elongated members 701, 702 to the support column 11 are elongated holes extending in the extending direction of the bracket 6, and accordingly Thereby, in the state temporarily fixed with the bolts 703a, 703b and the nuts 704a, 704b, these first and second elongated materials 701, 702 are supported so as to be slidable along the extending direction of the bracket 6, Positioning when attaching these members to the column 11 can be easily performed. At this time, since the front and rear positions of the soundproof panel 5 (positions in the extending direction of the bracket 6) are defined by the front and rear positions of the first and second elongated members 701 and 702, the soundproof panel 5 can be easily aligned at the same time. Will be made. In addition, since the width of the rail member can be easily adjusted by sliding the first and second long members 701 and 702, the soundproof panel 5 having different thicknesses can be easily used. Can respond.

  In addition, in the mounting method of the soundproof panel 5, a) a rail member is supported and fixed to the mounting surfaces 6R and 6L of the bracket 6 with a space between the support column 11 and b) a soundproofing to the rail member. Since the panel 5 is inserted and fixed, it is possible to efficiently and easily attach the soundproof panel. That is, when performing the mounting operation, the soundproof panel 5 can be easily guided to the mounting position by fitting the soundproof panel 5 into the rail member having a U-shaped cross section. Further, the mounting operation can be performed in a state where the soundproof panel 5 is held at the mounting position, and the operator does not need to hold the soundproof panel 5 directly at the mounting position. Therefore, it is easy to attach the soundproof panel and the work efficiency is good.

(Modification)
In the mounting structure of the soundproof panel 5, the support member for supporting and fixing the rail member to the support column 11 is not limited to the bracket 6 made of the rectangular plate as described above. An arbitrary shape such as a shape or a fan shape can be used, for example, as shown in FIG. 5, a horizontal portion 611 a disposed so as to extend in a strip shape in the horizontal direction from the support 11, and A bracket 611 composed of a cane portion 611b installed obliquely between the support column 11 so as to support the horizontal portion 611a from below can also be used. Two brackets 611 shown in the figure are formed in the horizontal portion 611a so that two bolt insertion holes extending in the front-rear direction, that is, in the extending direction of the horizontal portion 611a are juxtaposed in the front-rear direction. Both surfaces of the frame portion 611a serve as attachment surfaces, which can function substantially the same as the bracket 6 made of the rectangular plate material and are lightened.

  In addition, since the rail member is fixed to only one of the mounting surfaces 6R and 6L on both sides of the bracket 6 and the soundproof panel 5 is mounted at the end or corner of the soundproof wall 1, the end or corner As a part-dedicated bracket, the soundproofing panel 5 may have a mounting surface only on one surface to which the soundproof panel 5 is mounted, and the other surface may have an arbitrary configuration. It is good also as a bracket (not shown) which gave decoration etc.

  Moreover, as a rail member, as shown in FIG. 6, for example, as shown in FIG. A rail member may be formed by bending a plate into a U-shaped cross section or a long member 711 made of channel steel. Furthermore, as a rail member, in addition to the long member extending in the height direction, for example, a relatively short member may be arranged at a plurality of positions in the height direction. Good.

  In the mounting structure of the soundproof panel 5, as shown in FIG. 7, a rail member composed of the first and second long members 701 and 702 and a frame fitted on both side end surfaces of the soundproof panel 5. A space portion 503C communicating in the height direction is formed so as to be surrounded by the groove portion on the inner side of the material 503, and as shown in the figure, the space portion 503C includes the above-described space portion 503C. A sound absorbing material 508 made of the same material as or different from the sound absorbing material 505 filled inside the soundproof panel 5 is filled, thereby providing sound absorbing properties to the gap portion 503C to prevent noise leakage, and as a soundproof wall Sound insulation can be improved.

  Further, in the mounting structure of the soundproof panel 5, as shown in FIG. 4, the bolt insertion holes 601a and 601b of the bracket 6 and the bolt insertion holes 702c of the second long member 702 are horizontally arranged in the front-rear direction, that is, It is a long hole extending along the extending direction of the bracket 6, and both bolt insertion holes 701 c and 701 d of the first long material 701 are round holes. Both bolt insertion holes 601a and 601b may be round holes, and both bolt insertion holes 701c and 701d of the first elongated member 701 and bolt insertion holes 702c of the second elongated member 702 may be elongated holes similar to the above. Also in this case, the first and second long members 701 and 702 are extended in the extending direction of the bracket 6 in a state where the bolts 703a and 703b and the nuts 704a and 704b are temporarily fixed. It is slidably supported me. However, in this case, the first long members 701 and 701 on both sides of the bracket 6 are not restrained by each other and can be slid individually.

  Further, in place of the soundproof panel 5 having the structure in which the groove portions are formed by the frame members 503 on both side end surfaces, for example, as shown in FIG. 8, a soundproof panel 510 having no groove portions on the side end surfaces is provided. It can also be used. In the example shown in the figure, a frame member 530 made of a metal plate having a U-shaped cross section is fitted on both side end faces of the soundproof panel 510 with the inner groove-like portion facing inward, thereby The both ends of the soundproof panel 510 are closed so as to be covered from the outside, and the extended pieces as in the above embodiment are not formed. In this case, both end portions of the soundproof panel 510 are fixed by appropriate means such as screws while being inserted into the rail member.

  In addition to these, a soundproof panel having any shape may be used as long as it can be fitted into the rail member. For example, the punched metal used as the first face plate 501 of the soundproof panel 5 may be used. In addition, a material made of another porous material such as a mesh sheet is used, a resin plate such as polycarbonate or acrylic is used instead of the metal plate used as the second face plate 502, or the sound absorbing material 505 is used. What is known as a soundproof panel, such as rock wool, metal fiber such as aluminum fiber, other sound absorbing material such as ceramic particles, or a part or all of the soundproof panel made of precast concrete Can be used.

  Further, the soundproof panel mounting structure similar to that of the above-described embodiment is composed of a pillar made of a square steel pipe or a round steel pipe, a pillar, a beam, etc. in addition to the pillar 11 made of H-shaped steel as described above. Any structure can be applied as long as the supporting member can be disposed, such as a frame or a structural wall. According to the soundproof panel mounting structure similar to that of the above-described embodiment, in addition to being excellent in appearance without being exposed to the underlying structure, it can be applied to any structure. In addition, an effect equivalent to that applied to the column 11 made of H-shaped steel as described above can be obtained, such as being able to attach a soundproof panel without interfering with any protruding portion.

  Furthermore, in the said embodiment, although the attachment structure of the soundproof panel in the case of suppressing the noise which generate | occur | produces from an outdoor unit is illustrated, the attachment structure of the soundproof panel similar to the said embodiment is such an outdoor unit. In addition to the installation location, the present invention can be applied to a wide range of noise generation locations such as roads such as expressways and railways. In addition, depending on a noise generation location, the positional relationship of members constituting the soundproof wall may be changed. For example, in the above embodiment, the soundproof panel 5 is attached to the side of the support 11 opposite to the side where the noise source is located. Conversely, the soundproofing panel 5 is attached to the side of the support 11 where the noise source is located. A case where the panel 5 is attached is also conceivable. In this case, the soundproof panel 5 is attached with the front and back reversed, that is, with the first face plate 501 facing outward and the second face plate 502 facing inward (the column 11 side).

  The present invention can be applied to any soundproof wall having a structure in which a soundproof panel is attached to the structure, and is widely applied to various soundproof walls constructed in outdoor unit installation locations, roads, railways, etc. It is possible to apply.
