  For example, considering the work of attaching a large number of sound absorbers to the wall surface, it may be desired to adjust the sound absorber attachment position. In response to such a request, as described in Patent Document 2, in the work mode in which the screw is inserted into the screw hole of the fixed piece, there is room for improvement because it takes time to mount and it is difficult to change the mounting position. .

On the other hand, as described in Japanese Patent Application Laid-Open No. H10-228707, the use of Velcro tape (registered trademark), double-sided tape, or the like facilitates the attaching operation and can easily adjust the attaching position.
However, in the configuration of Patent Document 1, it is necessary to attach Velcro (registered trademark), double-sided tape or the like for each attachment location of the sound absorbing material on the wall surface, and there is room for improvement in terms of taking time and labor for this attachment. .

  The objective of this invention exists in the point which comprises rationally the attachment structure which can attach a sound-absorbing material with respect to attachment object easily.

  According to a first characteristic configuration of the present invention, a first surface fastener is provided in a portion including at least four corners on a rectangular back surface of the sound absorbing material, and the first surface fastener provided on the sound absorbing material and the sound absorbing material are different from each other. A second surface fastener that engages with the first surface fasteners provided on the sound absorbing material is provided on at least one of the attachment target portions of the wall portion, the ceiling portion, and the floor portion, and the sound absorbing material forms fibers in a lump shape. By doing so, a back surface on which the first surface fastener is provided is formed, and the fiber is exposed to the back surface in a state that it can be engaged with the second surface fastener.

According to this configuration, the first surface fastener is provided in a portion including the four corners on the back surface of the sound absorbing member, and the second surface fastener is provided in an attachment target portion such as a wall surface, whereby the sound absorbing material is engaged with the attachment target. It can be attached in a form, and since the engagement can be easily released, the position can be easily adjusted. In addition, since the first surface fastener of the predetermined sound absorbing material is engaged with the second surface fastener provided on the attachment target, and the first surface fastener of a different sound absorbing material is engaged with the second surface fastener, For example, when compared with a work configuration including a second surface fastener for each sound absorbing material, the number of second surface fasteners attached to the attachment target is reduced, thereby reducing the work effort.
Therefore, the attachment structure which can attach a sound-absorbing material with respect to attachment object easily was obtained.

  Since the sound absorbing material is formed by massing the fibers, the sound absorbing effect is obtained and the fiber is exposed on the back surface of the sound absorbing material. Therefore, the first surface fastener provided on the back surface is engaged with the second surface fastener. In this case, the fiber exposed on the back surface of the sound-absorbing material can be engaged with the second surface fastener, thereby realizing more reliable engagement.

  According to a second characteristic configuration of the present invention, a fixing bracket for fixing the sound absorbing material to the mounting target portion is provided, and the fixing bracket is fixed to the mounting target portion in a state of penetrating the sound absorbing material in the front and back direction. And a restricting portion that is provided at a tip of the penetrating support portion and prevents the sound absorbing material from being separated from the attachment target portion.

  According to this, in a state where the sound absorbing material is held in the attachment target portion by engaging the first surface fastener and the second surface fastener, the fixing bracket is passed through the sound absorbing material, and the support portion of the fixing bracket is attached to the attachment target portion. It can be fixed to the attachment target part by bringing the regulating part into contact with the sound absorbing material. In other words, by using the engagement between the first surface fastener and the second surface fastener, the sound absorbing material is mounted at an appropriate position of the mounting target portion, and in this mounted state, the fixing is realized by the fixing bracket. .

According to a third characteristic configuration of the present invention, a first array and a second array in which a plurality of the sound absorbing materials are arranged and connected in a line are arranged adjacent to each other in the array width direction, and the second surface fastener is arranged in the first array. And having a width extending across both arrays across the boundary of the second array, and having a long shape along the longitudinal direction of the array.
According to this, the first array is configured by connecting a plurality of sound absorbing materials side by side, and the second array is configured by connecting the plurality of sound absorbing materials side by side in the same manner. Compared to handling, the work is reduced. In addition, since the long second fastener is attached to the attachment target, the first fastener at the boundary between the first array and the second array is engaged with the second fastener. Can be further reduced.

The 4th characteristic structure of this invention exists in the place which provided the pressing member which fixes the said 2nd surface fastener with respect to the said attachment object part.
According to this, since the second surface fastener is fixed to the attachment target portion by the pressing member, the first surface fastener of the sound absorbing material is engaged with the second surface fastener, and the weight of the sound absorbing material acts. The sound absorbing material can be held at an appropriate position without changing the positional relationship between the second surface fastener and the attachment target portion.

It is a perspective view which shows the structure which attaches a sound-absorbing material to a wall part. It is a front view which shows the sound absorption material attached to the wall part. It is sectional drawing which shows the sound-absorbing material attached to the wall part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1-5, the 1st surface fastener F1 is provided in the back surface 1 of the sound-absorbing material A, the 2nd surface fastener F2 is provided in the surface of the indoor wall part 10 as an attachment object part, and a 1st surface fastener is provided. By engaging the second surface fastener F2 with F1, the sound absorbing material A is attached to the wall portion 10, and in this attached state, an attachment structure is formed in which the fixing bracket 20 penetrates the sound absorbing material A and is fixed to the wall portion 10. .

  This mounting structure forms the sound absorbing material A on the wall or ceiling wall in order to achieve sound absorption of the wall 10 or ceiling in a school music room or an anechoic facility for recording audio. This mounting structure does not target the wall 10 or the ceiling wall, but may use the floor as the mounting target.

  The sound absorbing material A is formed into a lump by combining resin fibers, glass fibers, and the like with a binder or the like in a state where a sound absorbing space is formed between the fibers. The lump formed in this way includes, for example, a back surface 1 that is a square, a block-shaped base portion 2 that rises from the back surface 1, and a pair of projecting portions 3 that project from the base portion 2 in a tapered manner. It becomes a sound-absorbing wedge shape. In addition, a valley-like portion 4 is formed at an intermediate portion between the pair of projecting portions 3, and a tapered surface 5 having an inclined posture continuous from the projecting portion 3 is formed.

  The sound absorbing material A has a function of absorbing sound waves in an internal sound absorbing space, and fibers are exposed on the surface in a raised state. Further, the sound absorbing material A may be one that covers the surface of the fiber of the lump with a cloth material or a paper material that can transmit sound waves. Even in such a configuration, the back surface 1 is configured so that the fibers of the lump are exposed in a raised state (engageable state) with the second surface fastener F2.

  Since the fibers are exposed in the raised state on the back surface 1 of the sound absorbing material A in this way, the first surface fastener F1 on the back surface 1 is related to the second surface fastener F2 on the wall portion 10 in order to attach the sound absorbing material A to the wall portion 10. When they are combined, the fibers exposed on the back surface 1 can be engaged with the second surface fastener F2. Accordingly, for example, even when the engagement force is insufficient, such as when the first surface fastener F1 and the second surface fastener F2 are not in an appropriate positional relationship, the fibers constituting the sound absorbing material A and the second surface fastener F2 are used. A strong engagement is achieved by the engagement. Further, when the sound absorbing material A is attached, the first surface fastener F1 and the second surface fastener F2 are engaged with each other. For example, even when the attachment position is adjusted, the engagement is released to achieve an appropriate position. Change work can be done easily.

  In the present invention, the first surface fastener F1 and the second surface fastener F2 are called Velcro (registered trademark) or Velcro (registered trademark). Moreover, what formed many loop-shaped parts which a fiber raises is used as 1st surface fastener F1, and what formed many hook-shaped parts engaged with a loop-shaped part is used as 2nd surface fastener F2. ing.

  In this mounting structure, a tape-like (long) shape is used as the second surface fastener F2, which is brought into close contact with the surface of the wall portion 10 in a posture along the vertical direction, and the wall portion is supported by the support 11 as a pressing member. 10 is fixed. For example, as shown in FIG. 3, the support 11 is formed in a U shape by providing a pair of legs 11 </ b> B with respect to the support main body 11 </ b> A using a metal material, and the longitudinal direction of the support main body 11 </ b> A. Is set in the vertical direction so as to follow the line of the boundary portion of the adjacent sound absorbing material A, and the leg portion 11B is fixed in such a manner as to penetrate the second surface fastener F2 and be driven into the wall portion 10.

  A tape-like one is also used for the first surface fastener F1. As shown in FIG. 3 and FIG. 4, when the width of the first surface fastener F1 is W1, the width of the second surface fastener F2 is set to, for example, twice the value of W1. This 1st surface fastener F1 is attached in the form which adhere | attaches on the back surface 1 of the two sound-absorbing materials A which comprise an array.

  In this mounting structure, it is reasonable to provide the first surface fasteners F1 in the region including the four corners of the back surface 1 of the sound absorbing material A in order to suppress the lifting of the sound absorbing material A and perform reliable engagement. Accordingly, the first surface fastener F1 may be provided with squares having a width W1 as one side at the four corners of the back surface 1 of the sound absorbing material A without using a tape-shaped one. Furthermore, in order to enable reliable connection of the sound absorbing material A, a first surface fastener F1 may be provided on the entire back surface 1 of the sound absorbing material A.

  The support 11 may use nails or screws other than the U-shaped support. Moreover, in the mounting structure of this invention, you may fix the 2nd surface fastener F2 to the wall part 10 by adhesion | attachment, without using the support body 11. FIG. The material of the support 11 is not limited to metal but may be resin or wood.

  As shown in FIGS. 3 and 5, two sound absorbing materials A are arranged in a line and connected by bonding or the like to form two sound absorbing materials as one array. The array is set to a posture in which the posture of the protruding portion 3 of one sound absorbing material A and the posture of the protruding portion 3 of the other sound absorbing material A are orthogonal to each other. As described above, since the width W2 of the second surface fastener F2 is set to twice the width W1 of the first surface fastener F1, for example, one of the arrays is referred to as the first array, and the other one array When the first array and the second array are arranged adjacent to each other in the width direction and attached to the wall portion 10, one second surface fastener F2 is used as the first array fastener of the first array. Engage F1 and first surface fastener F1 of the second array.

  That is, the second surface fastener F2 is formed in a region extending across both arrays across the boundary between the first array and the second array, and the width W2 of the second surface fastener F2 is equal to that of the first array and the second array. Since the width W1 of the first surface fastener F1 provided for the two arrays is twice the width W1, the first surface fastener F1 of the first array is engaged with the half of the engaging surface of the second surface fastener F2, The first surface fastener F1 of the second array is engaged with the remaining half region of the engagement surface of the two surface fastener F2.

  In the case of configuring an array, three or more sound absorbing materials A may be connected, and four or more sound absorbing materials A may be arranged in a planar shape to configure the array. In order to connect the plurality of sound absorbing materials A, an adhesive tape may be wound around the outer periphery of the base 2 of the plurality of sound absorbing materials A, or a rod or the like may be connected to the adjacent sound absorbing material A.

  As shown in FIGS. 3 to 5, the fixture 20 is formed in a nail shape having a rod-shaped support portion 21 with a sharpened tip side and a restricting portion 22 for retaining the base end side. Yes. When the sound absorbing material A is fixed to the wall portion 10 from such a structure, the tip of the support portion 21 is driven into the wall portion 10 with the support portion 21 penetrating through the sound absorbing material A in the front and back direction, and the restricting portion 22. Is brought into contact with the outer surface of the sound absorbing material A to prevent the sound absorbing material A from being separated from the wall portion 10.

  As shown in FIG. 4 and FIG. 5, two locations of the two taper surfaces 5 on the outer peripheral side of the sound absorbing material A, and a valley-shaped portion as positions where the support portion 21 of the fixing metal 20 penetrates the sound absorbing material A Although a total of five locations including one location in the central portion of 4 are assumed, this is not restrictive. The restricting portion 22 of the fixture 20 may be configured to be detachable with respect to the support portion 21. For example, after the support portion 21 has penetrated the sound absorbing material A and is driven into the wall portion 10, the restricting portion 22 22 may be attached. The fixing bracket 20 is used in a form that penetrates the sound absorbing material A and is driven into the wall portion 10, and is configured by a tapping screw that is fixed to the wall portion 10 in a form that is screwed into the wall portion 10. May be. Further, the tip of the support portion 21 may be bolt-shaped, and may be fixed by engaging with a fixing nut provided on the wall portion 10 in advance.

[Work form]
With such a configuration, when the sound absorbing material A is attached to the wall portion 10, two sound absorbing materials A are combined to form an array, and both end edges of the back surface 1 of the two sound absorbing materials A forming this array Two first surface fasteners F1 are fixed to each other by bonding or the like. Further, the plurality of second surface fasteners F <b> 2 are fixed to the wall portion 10 by the support 11 in a parallel posture that is vertically long and has an interval equal to the width of the sound absorbing material A.

  Next, the array is attached to the wall 10 in such a manner that the first surface fastener F1 is engaged with the second surface fastener F2. In the case of attachment in this way, the engagement and separation between the first surface fastener F1 and the second surface fastener F2 can be easily performed, so that the attachment position can be easily adjusted. In particular, since the fibers constituting the sound absorbing material A are exposed on the back surface 1 of the sound absorbing material A in a raised state, a part of the fibers of the raised body is engaged with the second surface fastener F2 to solve the lack of engagement force. it can. That is, when the array is attached to the wall portion 10, the boundary between adjacent arrays deviates from the center in the width direction of the second surface fastener F2, and the first surface fastener F1 of the array engages with the second surface fastener F2. The area to be used may be insufficient. Thus, even when the sound absorbing material A deviates from an appropriate position, the fibers exposed on the back surface 1 of the sound absorbing material A can be engaged with the second surface fastener F2.

  Further, when the array (sound absorbing material A) is attached by engagement, the first surface fastener F1 of one array is engaged with the half region in the width direction with respect to one second surface fastener F2, and the rest Since the first surface fastener F1 of the other array is engaged with the half of the area, it is not necessary to perform the operation of attaching the plurality of second surface fasteners F2 to the wall portion 10.

  Further, after the array is attached to the appropriate position of the wall portion 10 by the engagement of the first surface fastener F1 and the second surface fastener F2, the fixing bracket 20 penetrates the sound absorbing material A and is driven into the wall portion 10. Therefore, the fixed array (sound-absorbing material A) is prevented from falling off, so that secure fixing is realized.
