Description

[Technical field]

[0001] The present invention relates to a mounting structure for a sound-absorbing material. [Background technology]

[0002] In the ceiling space of buildings such as large arenas and halls, sound-absorbing materials are sometimes placed to improve acoustics. Patent Document 1 describes a method of suspending sound-absorbing materials made of porous concrete from a steel ceiling frame using metal hooks or the like to improve noise reduction in factories and the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-299120 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned ceiling space, truss steel frames and the like are arranged in a complex manner, and electrical and air conditioning piping and stage equipment are arranged on the maintenance floor, so it can be difficult to determine the placement of sound-absorbing materials as they may interfere with the truss steel frames, electrical and air conditioning piping, and stage equipment.In addition, it can be difficult to determine the amount of sound-absorbing material required for a large building such as an arena, and there was a demand for an installation structure that would allow flexible placement of sound-absorbing materials to deal with these uncertainties.

[0005] The present invention has been made in consideration of the above problems, and has an object to provide a mounting structure for a sound-absorbing material that allows the sound-absorbing material to be flexibly arranged. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides a mounting structure for sound-absorbing material, characterized in having a wire that is spanned across the space in which the sound-absorbing material is arranged, a hanging jig that is passed through the wire and has a main body with an opening and an openable / closable piece that closes the opening, a plate-shaped support material supported by the hanging jig, and plate-shaped sound-absorbing material attached to both sides of the support material.

[0007] According to the mounting structure of the present invention, the sound absorbing material can be easily arranged without requiring any large-scale construction work, by simply suspending the unit, which has the sound absorbing material already attached to the support material, from a wire or other material using a hanging jig. In addition, even after the unit is suspended, it can be easily moved or attached / detached, so that it is possible to flexibly respond to changes in the sound absorbing specifications and the addition or removal of sound absorbing materials. Therefore, even if the detailed layout of the electrical and air conditioning piping is uncertain, planning and construction can be carried out without waiting for the confirmation of these details. Furthermore, by providing sound absorbing materials on both sides of the support material, it is possible to realize an arrangement that does not hinder maintenance.

[0008] It is desirable that the support material be arranged so that its upper portion protrudes upward from the sound-absorbing material, and that a hole for passing the hanging jig be provided in the upper portion of the support material. This prevents the attachment points of the hanging jig to the unit from loosening due to vibrations caused by loud noises, making it possible to reliably support sound-absorbing materials, etc., for long periods of time.

[0009] It is desirable that a turnbuckle be provided at the end of the wire for tensioning the wire. This allows the wire or other material to be easily tensioned and made taut.

[0010] It is desirable that the sound absorbing material be attached by being inserted into pins provided on the support material. This makes it easy to attach the sound absorbing material to the support material.

[0011] The support material is disposed, for example, over the entire surface of the sound-absorbing material. The mounting area of ​​the sound-absorbing material to the support material can be appropriately determined depending on the frequency of the sound to be absorbed, etc.

[0012] The arrangement space is, for example, the ceiling space of a building. The mounting structure of the present invention is provided in the ceiling space of a building such as an arena or hall, making it possible to flexibly arrange sound-absorbing material in the ceiling space. Effect of the Invention

[0013] The present invention can provide a mounting structure for a sound-absorbing material that allows flexible placement of the sound-absorbing material. [Brief description of the drawings]

[Diagram 3] A diagram showing the attic space S in which sound-absorbing material 2 is placed. [Figure 4] Examples of different mounting areas for sound-absorbing material 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0016] 1 is a diagram showing an installation structure 1 according to an embodiment of the present invention. This installation structure 1 is for disposing a sound-absorbing material 2 in the ceiling space of a building such as an arena or hall, and includes, in addition to the sound-absorbing material 2, a wire 3, a hanging jig 4, a support material 5, etc.

[0017] The sound absorbing material 2 is a plate-like member having sound absorbing properties, and is unitized by being attached to a support material 5. The sound absorbing material 2 is, for example, a glass wool board, but is not limited to this.

[0018] A plate-like member having an appropriate strength, such as a thin iron plate, is used as the support material 5. Although it is possible to use a wood material such as plywood as the support material 5, it is preferable to use an iron plate, which is a non-combustible material, in order to avoid the use of unnecessary combustible materials in the ceiling space.

[0019] 2 is a diagram showing a cross section in the thickness direction of a unit in which sound-absorbing material 2 is attached to support material 5. Sound-absorbing material 2 is fixed to both the front and back surfaces of support material 5 using pins 51. Note that black cloth is wrapped around the surface of sound-absorbing material 2 other than the surface where it is attached to support material 5, so that sound-absorbing material 2 cannot be seen by spectators in an arena, hall, etc.

[0020] The pin 51 is a spindle pin having a pin body 512 provided on one surface of a plate 511, and the other surface of the plate 511 is adhesively fixed to the support material 5. The sound-absorbing material 2 is attached to the support material 5 by being inserted into the pin body 512, and a cap 513 is provided on the tip of the pin body 512 protruding from the sound-absorbing material 2 to cover the tip.

[0021] An upper portion of the support material 5 protrudes upward from the sound-absorbing material 2. A hole 52 for passing the hanging jig 4 is provided in the upper portion. As shown in Fig. 1, a plurality of hanging jigs 4 (two in the illustrated example) are provided at intervals in the width direction of the support material 5, and a plurality of the holes 52 are also formed in the upper portion of the support material 5 corresponding to the positions of the hanging jigs 4.

[0022] 2, the hanging jig 4 is disposed through the wire 3, whereby the unit of the support material 5 and the sound absorbing material 2 is supported from the wire 3 by the hanging jig 4. The hanging jig 4 is a carabiner having a C-shaped main body 41 with an opening that can be opened and closed by an opening / closing piece 42. The opening / closing piece 42 is opened when the hanging jig 4 is attached to or detached from the wire 3, and the opening is normally closed by the opening / closing piece 42.

[0023] The wire 3 is a steel wire. As shown in Fig. 1, turnbuckles 31 for tensioning the wire 3 are attached to both ends of the wire 3. The turnbuckles 31 are fixed to a vertical member 111 in the attic space by a fixing member such as a clamp 32.

[0024] 3 shows an example of an attic space S of a building 100 in which a sound-absorbing material 2 is arranged. The space S is a space under a roof 130 of a large-scale building 100 such as an arena or hall, and a truss structure 110 is formed by vertical members 111 and diagonal members 112 on a maintenance floor 120, and the roof 130 is supported by the truss structure 110. In the example of FIG. 1, both ends of a wire 3 are fixed to the vertical members 111 via turnbuckles 31, clamps 32, etc., and the wire 3 is bridged across the attic space S. However, the object to which the wire 3 is fixed is not limited to the vertical members 111.

[0025] According to the mounting structure 1 of the present embodiment described above, the sound-absorbing material 2 can be easily arranged without requiring any large-scale construction work, by simply suspending the unit, in which the sound-absorbing material 2 has been previously attached to the support material 5, from the wire 3 by the suspension jig 4. In addition, even after the unit has been suspended once, it can be easily moved or attached / detached, so that it is possible to flexibly respond to changes in the sound-absorbing specifications, the increase or decrease in the amount of sound-absorbing material 2, etc. Therefore, even if the detailed layout of the ceiling space S for electrical / air conditioning piping, stage equipment, etc. is uncertain, planning and construction can be carried out without waiting for these to be determined.

[0026] Furthermore, compared to the case where the sound-absorbing material 2 is laid out on the maintenance floor 120 in the attic space S, by providing the sound-absorbing material 2 on both sides of the support material 5 as in this embodiment, it is possible to realize an arrangement that makes use of both sides of the support material 5 and does not hinder maintenance.

[0027] The hanging jig 4 is attached to the support material 5 by passing it through a hole 52 in the support material 5 that protrudes upward from the sound-absorbing material 2. By attaching the hanging jig 4 as described above without using screws or bolts, the attachment point will not come loose due to vibrations caused by loud noise, and the sound-absorbing material 2 and the like can be reliably supported for a long period of time.

[0028] Further, a turnbuckle 31 for tensioning the wire 3 is provided at the end of the wire 3, and the turnbuckle 31 allows the wire 3 to be easily tensioned and made taut.

[0029] Moreover, the sound absorbing material 2 can be easily attached to the support material 5 by being inserted into the pins 51 provided on the support material 5 .

[0030] However, the present invention is not limited to the above embodiment. For example, in this embodiment, the sound absorbing material 2 is arranged using the wire 3, but a wire material other than the wire 3 can be used. The hanging jig 4 is also not limited to the carabiner described above, and may have any body having an opening and an openable / closable piece that closes the opening.

[0031] Although the mounting structure 1 of this embodiment is for disposing the sound-absorbing material 2 in the ceiling space S of an arena, hall, etc., the arrangement space of the sound-absorbing material 2 is not limited thereto. For example, it may be used above a machine room that generates a large amount of noise.

[0032] Furthermore, in this embodiment, the support material 5 is disposed over the entire surface of the sound-absorbing material 2, but this is not limiting, and as shown in Fig. 4, the support material 5 may be disposed on part of the surface of the sound-absorbing material 2. The attachment area of ​​the sound-absorbing material 2 to the support material 5 can be appropriately determined according to the frequency of the sound to be absorbed, etc., and this allows the thickness of the sound-absorbing material 2 to be changed (in positions where there is no support material 5, the front and back sound-absorbing materials 2 can be considered as one unit and the thickness increases), and the sound absorption rate can be adjusted according to the frequency of the sound to be absorbed, etc.

[0033] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above examples. It is clear that a person skilled in the art can come up with various modified or altered examples within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally belong to the technical scope of the present invention.
