Description

  The present invention constructs a soundproof house and a soundproof house, which are buildings that are temporarily provided during work to prevent sound from leaking outside by surrounding the entire work target. The present invention mainly relates to a soundproof sheet used for the above.

For example, to dismantle a building or the like, the building is destroyed and fragmented using a heavy machine such as a power shovel at a demolition site, and the resulting waste is separated and discarded by an appropriate method.
When such dismantling work is performed in the vicinity of a residential area, a hospital, a school, or the like, a problem of noise is likely to occur. Since a building often includes a material such as glass that generates a loud sound when dismantled, the sound generated during dismantling work often has a level of noise. In the past, there have been a number of cases in the past where complaints have arisen from neighbors etc. when dismantling work was performed without any special allowance.

2. Description of the Related Art A soundproofing house is used as one of techniques for preventing the noise generated by an operation such as the demolition of a building from spreading to the surroundings.
A soundproof house is a temporary building made around the time when work is performed, surrounding a target area (eg, the entire building to be demolished) where work is performed.

Some soundproofing houses are, roughly speaking, huge temporary tents. After assembling columns, beams, and roofs with rod-shaped aggregates, they are covered with a membrane to create a soundproof house.
Of course, if the mere film material covers the soundproof house, the soundproof effect is small. Therefore, the following two approaches are mainly used.
The first is to use what is also called a high soundproofing sound-insulating material, which is filled and sealed with a cotton-like or sponge-like sound-absorbing material having soundproofing performance between the double-layered film materials. Things.
The second is a soundproofing panel made of, for example, gypsum board or wood, or a panel in which they are mounted on a metal frame, for example. By mounting the panel on an aggregate or the like, the entire wall of the soundproof house is covered with the soundproof panel, or in some cases, the entire roof is similarly covered with the soundproof panel.

The method using the above-mentioned soundproofing film material has an advantage that it is relatively easy to mount the soundproofing house or its aggregate material.
However, since the soundproofing film material needs to be wound up or folded when transporting or the like, the thickness cannot be increased so much, and the sound absorbing material to be filled between the double film materials. It cannot be filled as much as necessary for the soundproofing film material to have high soundproofing performance. On the other hand, when the amount of the sound absorbing material to be filled between the two membrane materials is increased, the portability is deteriorated. In addition, since the sound absorbing film material covers the sound absorbing material with the film material, the sound that hits the sound insulating film material is not absorbed by the sound absorbing material of the sound insulating film material but is reflected by the film material outside the sound absorbing film material. That is, especially in the case of considering portability, the soundproofing film material is often not sufficient in terms of essential soundproofing performance.
In addition, the above-described soundproof panel is generally superior to the soundproof film material in terms of soundproof performance in many cases.
However, it is troublesome to attach a large number of generally rectangular soundproof panels to the aggregate of the soundproof house using bolts and the like in a grid pattern, using bolts or the like. Installation work is troublesome. Further, when soundproof panels having different sizes and thicknesses are used, different jigs are required when attaching them to the aggregate of the soundproof house.

  An object of the present invention is to propose a film material which has a high soundproofing effect, is easily attached to the soundproofing house, and has high portability, and also proposes a soundproofing house to which such a material is applied. That is another task.

In order to solve the above-mentioned problem, the present inventor proposes the following invention.
The present invention relates to a film material main body that can be wound or folded, and provided on one surface of the film material main body, when the film material main body is attached to a soundproof house, a rectangular with a predetermined thickness. The sound-absorbing mat is configured to be detachably fixed to each of the sound-absorbing mats in a state where most of its inner surface is exposed, and is flexibly configured so that the winding or folding of the membrane main body is not impossible. A plurality of fixing members for fixing the sound-absorbing mats in such a manner that their longitudinal directions are kept substantially horizontal and are arranged vertically in parallel.
The film material according to the present invention is adapted to be attached to, for example, a pillar of a soundproof house. The film material main body constituting the film material has a fixing member, and the sound absorbing mat can be detachably attached to the fixing member of the film material attached to the soundproof house. The fixing of the membrane material to the aggregate such as the pillars constituting the soundproof house according to the present invention may be the same as the method of fixing the film material to the soundproof house described in the related art, and is not particularly difficult. Further, fixing the sound-absorbing mat to the film material does not require bolts or jigs, and is not particularly difficult. Therefore, if this film material is used, it is easy to attach the sound absorbing mat to the soundproof house.
Further, the sound absorbing mat fixed to the fixing member of the film material according to the present invention has a state in which most of the inner surface is exposed. In the present application, the inner surface of the sound absorbing mat means a surface facing the inside of the soundproof house. Therefore, in the soundproof house made using the film material of the present invention, the inner surface of the sound-absorbing mat to which the sound in the soundproof house is applied does not cover all or any part of the mat. Therefore, the soundproof performance is high. Since the sound-absorbing mats fixed to the fixing member of the film material keep their longitudinal directions substantially horizontal and are vertically aligned, the soundproof performance of the soundproof house made using the film material of the present invention is achieved. This is even more so.
Further, the film material main body of the present invention can be wound or folded. Further, the fixing member fixed to the film material main body is configured to be flexible so that the winding or folding of the film material main body is not made impossible. As a result, the film material of the present invention can be rolled up or folded as a whole. When constructing a soundproof house, or when disassembling a soundproof house, with the membrane material of the present invention and a number of sound absorbing mats attached thereto removed, and with the former wound or folded, It is possible to transport the film material and the sound absorbing mat. In other words, the film material of the present invention, or a film material set in which the film material of the present invention is combined with a sound-absorbing mat detachably attached thereto is highly portable.

  The specific configuration of the fixing member is not limited as long as it is as described above. Considering that the fixing member is required to have flexibility, it is easy to use the fixing member as one of a fixing string which is a string or a band-shaped film material formed as a band-shaped film material. The film material constituting the film material may be made of the same material as the film material main body which is the film material, but it is not necessary to be so.

Although not limited thereto, the fixing members may be paired so as to fix the sound absorbing mat at both ends in the longitudinal direction or in the vicinity thereof. By doing so, the sound absorbing mat can be attached to the film material of the present invention in a stable state.
There is no particular limitation on the shape of the film material main body. The film material body may be rectangular, more specifically, a rectangle whose longitudinal direction is the vertical direction when used (for example, the film material of the present invention is attached to a pillar and is substantially vertical). Good. In this case, the fixing members may be paired at the same height at both ends in the short direction or in the vicinity thereof. According to this, it is easy to keep the sound absorbing mats in a state where their longitudinal directions are substantially horizontal and to arrange them vertically.

As described above, the fixing member may be a band-shaped film material. In this case, both ends of a portion of the band material used for fixing one of the sound absorbing mats may be fixed to the film material main body. In this way, a loop surrounded by the outer surface of the film material and the inner surface of the film material main body is formed between both ends of the film material used for fixing one sound absorbing mat. By simply inserting the rectangular end of the sound-absorbing mat or the vicinity thereof into the loop, the sound-absorbing mat is detachably fixed to the fixing member while keeping the longitudinal direction substantially horizontal. It can be easily realized. Of course, the cross section of the above-mentioned loop is shaped and sized so that when the end of the sound absorbing mat or its vicinity is inserted inside it, the membrane material can be fixed by the loop made of the fixing member and the band material. Is done.
In this case, the film material may be long, and may be fixed to the film material main body at both ends in the length direction and at a plurality of predetermined positions in the middle of the length direction. Alternatively, the film material may be divided into lengths necessary for fixing one sound-absorbing mat, and both ends in the length direction of each of the divided film materials may be fixed to the film material body. good. That is, each of the band members may be fixed to the film body at both ends in the length direction. Either of them can be adopted, but considering the number of fixing points of the film material and the film material main body, it is considered that the former is easier to manufacture and the manufacturing cost is lower.
The film material may have elasticity in its length direction. According to this, the cross section of the above-mentioned loop formed between the fixing member which is a band material and the film material main body is inserted into the end or the vicinity thereof at the sound absorbing portion. By making it one size smaller than the cross section of the mat, when the end portion or the vicinity of the sound absorbing mat is inserted into the loop, the fixing of the sound absorbing mat by the fixing member and the film material main body constituting the loop becomes more efficient. It can be strong. Moreover, the cross section of the sound absorbing mat is not always constant. For example, when higher soundproof performance of the soundproof house is required, the thickness of the sound absorbing mat may be increased. If the fixing member made of a film material has elasticity in its length direction, there is a slight change in the cross-sectional shape of the sound-absorbing mat, although there is a limit due to its elasticity. Even if the sound absorbing panel is changed in the prior art, the sound absorbing mat can be detachably fixed to the same film material without the necessity of changing the jig which is necessary when the structure of the soundproof panel is changed. .

As described above, the fixing member of the present invention may be a pair of two in order to fix the sound absorbing mat at both ends or in the vicinity thereof. In this case, between the pair of fixing members, the sound-absorbing mat is supplementarily detachably fixed, so that even when the sound-absorbing mat is fixed, most of the inner surface of the sound absorbing mat is exposed. It is possible to provide an auxiliary fixing member which is configured to be in a state in which the film material body is rolled up or folded so as not to be impossible.
That is, two or more fixing members may be combined into three or more.

The film material described above can be used to construct a soundproof house. One example is a soundproof house for preventing sound leakage from a predetermined target range, which covers a plurality of pillars surrounding the target range and adjacent ones of the pillars. And a sound absorbing mat attached to the fixing member of the film material.
In this case, the film material of the present invention may be used in place of a conventional film material having no fixing member. Further, the film material of the present invention may be used so as to be located inside a conventional film material having no fixing member.
In any case, if the film material of the present invention is used to cover between adjacent ones of the columns, it is used to cover the space between adjacent columns with a plurality of film materials. Alternatively, it may be used so as to cover one or more adjacent ones between adjacent pillars with one film material. If the soundproof house has a roof, the film material of the present invention can naturally be used for covering the roof.

The present inventor also proposes the following soundproof house construction method as an invention for solving the problems of the present invention.
The method is a method for constructing a soundproof house for preventing sound leakage from a predetermined target range, and winding between adjacent ones of a plurality of pillars surrounding the target range. Or a process of covering with a foldable film material main body, and, on the inner surface of the film material main body, a sound absorbing mat of a predetermined thickness, with most of the inner surface being exposed, Fixing the sound-absorbing mat to the film material main body, wherein the needle portion of the pin having a needle portion as a needle and a head having a diameter larger than that of the needle portion is included. By passing through the outer surface of the film material main body and further penetrating the sound absorbing mat.
In this case, the film material main body used may be a simple film material used when constructing a soundproof house or tent in the related art. In this method, a sound absorbing mat is fixed to the inner surface of the film material. The sound-absorbing mat is fixed to the surface of the membrane material body facing the inside of the sound-proof house in order to bring out the sound-proof performance. Since the fixing method is such that the needle of the pin penetrates the film material main body and the sound absorbing mat collectively, the fixing of the sound absorbing mat to the film material main body is easy.
In such a method for constructing a soundproof house, it is possible to bend the tip of the needle portion that has penetrated the sound absorbing mat, so that the sound absorbing mat can be securely fixed to the film material main body. . Further, it is also possible to bend the tip of the needle portion penetrating the sound absorbing mat after penetrating the hole of the washer. According to this, the sound absorbing mat can be more firmly fixed to the film material main body by the washer.

  Hereinafter, preferred first to third embodiments of the present invention will be described in detail with reference to the drawings. In the description of each embodiment, common objects will be denoted by the same reference numerals, and redundant description will be omitted as the case may be.

<< 1st Embodiment >>
First, a film material used in the first embodiment will be described.
FIG. 1A shows a front view of the film material 100, and FIG.
The film material 100 includes a film material main body 110. The film material main body 110 may be the same as a general film material used for covering a general soundproof house. The film material main body 110 can be, for example, a resin sheet or a sheet in which at least one surface of a woven or knitted fabric made of fiber is coated with a resin. Examples of the resin constituting the film material 100 include chloride. It is a vinyl resin, polyethylene, or the like, and the thickness of the film material main body 110 is, for example, 1.2 mm to 2.0 mm. The film material main body 110 can be wound or folded, but in this embodiment, both are possible.
Although not limited to this, the film material main body 110 is a long rectangle.
On one surface of the film material main body 110, a film material 120 which is a band-shaped film material as an example of the fixing member of the present invention is attached. The material of the band material 120 is made of a flexible material that does not make it impossible to wind or fold the film body 110 even when it is attached to the film body 110. As a result, the film material 100 can be rolled up or folded as a whole, and in this embodiment, both are possible. Although not limited to this, the material of the film material 120 of this embodiment is the same as the material of the film material main body 110. In this case, the band material 120 does not have elasticity in the length direction.

The band material 120 is long, though not necessarily limited thereto. Although not limited, the length of the film material 120 of this embodiment is the same as the length of the film material main body 110. Although not necessarily limited to the above, the band material 120 is positioned with respect to the film material main body 110 at both ends in the length direction (not shown) and a plurality of predetermined mounting portions 121 in the middle thereof. Fixed. Although not limited to this, the mounting portions 121 in this embodiment are configured such that the interval between adjacent mounting portions 121 is constant. The fixing method of the band material 120 to the film material main body 110 may be any method, and if both are fixed firmly, it is possible to perform the fixing by a known or well-known method. For example, the fixing method is heat fusion, adhesion, stitching, or the like.
As shown in FIG. 1B, a portion other than the attachment portion 121 of the film material 120, that is, a portion that is not fixed to the film material main body 110 is in a state of floating from the film material main body 110. In this portion, a loop is formed which is surrounded by the surface of the film material 120 on the film material main body 110 side and the surface of the film material main body 110 on the film material main body 120 side. In the present embodiment, the above-described loops generated between two adjacent mounting portions 121 are all the same size, but not limited thereto.
In this embodiment, the band material 120 is provided at or near both ends in the width direction of the film body 110 (in the figure, the band material 120 is provided near both ends in the width direction of the film body 110). ing.). In addition, the number of the attachment portions 121 in both the band members 120 and the height at which the attachment portions 121 are provided are the same in both the band members 120. Therefore, the number and the height (height in the direction of FIG. 1A) of the loops formed on both band film materials 120 coincide with each other. In other words, the loops arranged side by side in FIG. 1A are paired with each other. As described later, a pair of loops enables fixing of one sound absorbing mat.

  Note that the band material 120 does not necessarily have to be long, and as shown in FIG. 2, the band material 120 shown in FIG. 1 may be divided. In this case, both end portions of each of the band members 120 become attachment portions 121, and each of the band members 120 is fixed to the film body 110. Although not limited to this, the lengths of the respective banding materials 120 are all the same, the size of the two mounting portions 121 in each banding material 120, and the length of each banding material 120. The distance between the two attachment portions 121 is the same in any of the band members 120. Even when such a divided band material 120 is used, a loop surrounded by the surface of each band material 120 on the film material body 110 side and the surface of the film material body 110 on the film material body 120 side is formed. Will be done. Even when the divided band material 120 is used, the loops are all the same size, though not limited thereto.

  The film material 100 described above can be used to construct a soundproof house. Hereinafter, a method of constructing a soundproof house using the film material 100 and a configuration of the constructed soundproof house will be described.

The soundproof house is made to surround a target area, which is an area where some work that produces sound is performed. For example, a range surrounded by a dotted line in FIG. 3 is a target range. Although not limited to this, the target range in this embodiment is assumed to be a rectangle.
Although not shown, the target range includes, for example, an abandoned building. Some work that produces noise is, for example, the removal of a waste building.

In order to construct a soundproof house, as shown in FIG. 3, a number of pillars 1 are erected around the target area.
Each pillar 1 is made of metal, has a rod shape, and is higher than, for example, a waste building existing in the target area. Although not limited to this, in this embodiment, the heights of the columns 1 are all the same. The pillars 1 are erected at predetermined intervals, for example, at regular intervals. The interval between the pillars 1 is not limited to this, but is substantially equal to the lateral width of the film material 100 described above. In that case, the width of the film material 100 can be freely adjusted to match the interval between the columns 1, or the width of the column 1 can be freely adjusted to match the width of the film material 100.
Note that each column 1 does not need to be made of one column. For example, the column 1 may be divided in the height direction, and may be connected in the length direction. In addition, each column 1 is composed of four sub-columns 1a located on, for example, four corners of a square when viewed in a plan view, and can be connected by truss beams 1b connecting them in a truss shape. It is. An example of such a pillar 1 is shown in FIG.
A method of fixing the lower end of the pillar 1 to the ground may be in accordance with a known or well-known technique.

Then, although not necessarily required, in the soundproof house of this embodiment, adjacent columns 1 are connected by beams 2 (FIG. 4).
The beam 2 is made of metal. The beam 2 in this embodiment includes a horizontal beam 2A horizontal to the ground and a truss beam 2B inclined to the ground. Each of the horizontal beam 2A and the truss beam 2B has a role similar to that of a normal beam or truss structure, and enhances the rigidity of each column 1 by connecting adjacent columns 1. is there. Note that the beam 2 may include both the horizontal beam 2A and the truss beam 2B, or only one of them.
Note that the beam 2 does not necessarily need to be assembled to the column 1 after all the columns 1 have been erected.

Next, although not necessary, a roofing material 3 is provided on each pillar 1 (FIG. 5).
The roofing material 3 is fixed to the pillar 1 in a suitable manner. The roofing material 3 may have a structure similar to the above-mentioned wall made of the pillars 1 and the beams 2. Note that the roof material 3 is not necessarily required.
Also, the roofing material 3 does not necessarily need to be made after all of the columns 1 and the beams 2 have been constructed.

Then, the gap between the adjacent columns 1 and the above-described upper surface of the roof material 3 are covered with the film material 100 (FIG. 6). At this time, the surface of the film material 100 on which the film material 120 is attached faces the inside of the soundproof house.
The film material 100 is as described above.
In this embodiment, as described above, the width of the film material 100 is equal to the interval between the adjacent columns 1 (more precisely, the interval from the center to the center of the two columns 1). Further, in this embodiment, the length of the film material 100 matches the height of the column 1.
The membrane material 100 is fixed to appropriate portions of the pillar 1, the beam 2, and the roof material 3. A known or well-known technique can be used for fixing the membrane material 100 to the pillar 1, the beam 2, or the roof material 3. For example, an eyelet is struck on the edge of the film material 100, and the film material 100 can be fixed to the column 1 or the like by binding the film material 100 to the column 1 or the like with a string penetrating the eyelet. .
More specifically, the fixing of the film material 100 to the pillar 1 is performed in a state where the upper and lower ends of the film material 100 in the width direction are respectively aligned with the upper and lower ends of two adjacent pillars 1. At this time, both ends in the width direction of the film material 100 are respectively made to coincide with the center in the width direction of two adjacent columns 1. By performing this for all of the two adjacent columns 1, the film material 100 surrounds the outside or inside of the column 1 without any gap. Similarly, the inside or outside of the roof material 3 is surrounded by the film material 100.
FIG. 6 illustrates a case in which the membrane material 100 according to this embodiment covers the outside of the pillar 1 and the roof material 3. FIG. 7 illustrates a case where the inside of the pillar 1 and the roof material 3 is covered with the film material 100 according to this embodiment. In this case, as shown in the figure, the outside of the pillar 1 and the roof material 3 can be covered with a film material 190 which is a simple sheet without the film material 120, similarly to a conventional soundproof house. In addition, it is also possible to cover the film material 190 with the film material 100 in which the surface on which the band material 120 is attached faces the inside of the soundproof house. In this case, it is possible to fix the sound absorbing mat to the band material 120 of the inner film material 100 and the outer film material 100 as described later, thereby increasing the sound absorbing effect. Will be able to do it.
In this embodiment, the gap between two adjacent columns 1 is covered with a single film material 100, and in order to make it possible, the center of the two columns 1 in the width direction is set. The width from the center to the center and the width of the film material 100 are made to coincide with each other. However, the interval between the adjacent columns 1 and the lateral width of the film material 100 do not necessarily need to match. It is also possible to collectively cover two or more adjacent pillars 1 in a gap between two adjacent pillars 1 with one film material 100, and to have a width wider than the interval between two adjacent pillars 1 The degree of fixing the film material 100 to the column 1 while connecting the width direction ends of the adjacent film materials 100 to each other so that the width of the film material 100 whose width is not equal to the interval between two adjacent pillars 1 having a narrow width. Those skilled in the art will naturally be able to devise this.
Further, in this embodiment, the length of the pillar 1 and the length of the film material 100 in the vertical direction are set to be the same, but this is not necessarily the case. For example, those skilled in the art will naturally understand that a plurality of film materials 100 are connected in the vertical direction, and a device that covers a gap between two adjacent columns 1 can be devised.
The same applies to the case where the roof material 3 is covered with the film material 100.
Note that the fixing of the membrane material 100 to the pillar 1 and the roof material 3 can be started before all of the pillar 1 and the roof material 3 are completed.

After the pillars 1 and the roof material 3 are covered with the film material 100, the sound absorbing mat 200 is fixed to the film material 100 next.
The sound absorbing mat 200 is made of, for example, a material having a high sound absorbing property, and is formed by, for example, processing glass fiber into a mat shape. The sound-absorbing mat 200 is formed in a substantially rectangular shape (more precisely, a substantially rectangular parallelepiped shape) which is horizontally long when used, and its thickness is generally about 50 mm to 100 mm. Examples of the sound absorbing mat 200 include “Floating wool (trademark)”, an outdoor sound absorbing material manufactured and sold by Nippon Sheet Glass Environmental Amenities Co., Ltd., and materials for simple interior sound absorbing such as a machine room manufactured and sold by Asahi Fiberglass Co., Ltd. "Glass cloth wool (board) (trademark) / product symbol GW24-GW96" which is a material for heat insulation and sound absorption manufactured and sold by the company "Glaslon Wool (Roll) (trademark) / product symbol GW10-GW32", a material for heat insulation and sound absorption manufactured and sold, and "Feather Glass (Roll), a glass wool insulation and sound absorption material manufactured and sold by Paramount Glass Industry Co., Ltd. (Type) (trademark) "and" feather glass (board type) (trademark) ", a glass wool insulation, sound absorption and interior material manufactured and sold by the company That "GC board (TM)", can be given a mug-Izoberu Co., Ltd. is a glass wool products manufactured and sold "Magubodo (TM)" and "magnet roll (TM)". In the case of a roll-type product, a rectangular sound-absorbing mat 200 can be obtained, for example, by cutting the product at an appropriate length at the site.
In this embodiment, the width of the sound absorbing mat 200 is made to substantially match the width of the film material 100.

The sound absorbing mat 200 is fixed to the film material 100 as follows.
It is assumed that the film material 100 is as shown in FIG. In this case, the vicinity of both ends of the sound absorbing mat 200 is inserted into the two loops having the same height. Thereby, one sound absorbing mat 200 can be detachably fixed by a pair of loops. This is done for all loops in the pair. By doing so, each of the sound absorbing mats 200 is fixed to the film material 100 while keeping their longitudinal directions substantially horizontal. Further, the fixed sound absorbing mats 200 are arranged side by side in the vertical direction.
The vicinity of both ends of the inner surface of the sound absorbing mat 200 when fixed to the film material main body 110 is covered with the film material 120. However, in use, the horizontally-long sound absorbing mat 200 is supported by the pair of loops formed by the film material main body 110 and the band material 120 because the portion indicated by the loop of the sound absorbing mat 200 is As long as it is stable at both ends or in the vicinity thereof, there is no reason to increase the width of the band material 120. Therefore, as long as the non-wide band material 120 is used, it is easy to expose most of the inner surface (for example, 70% or more, preferably 80% or more) of the sound absorbing mat 200, and the performance of the sound absorbing mat 200 is sufficiently exhibited. It is also easy to do. In fact, also in this embodiment, 80% or more of the inner surface of the sound absorbing mat 200 is exposed.
It is preferable that the size and the shape of the above-described loop are appropriately set from the beginning according to the size and the shape of the cross section of the sound absorbing mat 200 to be used. For example, the distance between mutually adjacent positions of the mounting portions 121 located on both sides of the range in which one sound absorbing mat 200 of the film material 120 is fixed is equal to or slightly smaller than the length of the sound absorbing mat 200 in the short direction. Preferably it is long. Thereby, the sound absorbing mat 200 is more firmly fixed to the film material 100. However, as long as the sound absorbing mat 200 has some elasticity and can change its cross-sectional shape, the length of the above-mentioned loop does not necessarily need to be longer than the circumference of the cross section of the sound absorbing mat 200. Rather, in this case, the fixing of the sound absorbing mat 200 to the membrane material 100 will be stronger if the length of the loop is slightly smaller than the circumference of the cross section of the sound absorbing mat 200. Of course, in order to further firmly fix the both, it is also possible to perform further measures such as providing a Velcro tape on both the sound absorbing mat 200 and the inner surface of the loop.
The example described above is the case where the film material 120 does not have elasticity especially in the length direction. If the band material 120 has elasticity in its length direction, the size and shape of the above-described loop formed by the band material 120 and the film main body 110 are the same as those of the sound absorbing mat 200 to be used. Assuming that the size and shape of the cross section are adjusted to some extent, even if the length of the loop is smaller than the length of the circumference of the cross section of the sound absorbing mat 200, for example, the thickness of the sound absorbing mat 200 may be slightly changed. Even if there is, the above-mentioned loop enables the sound absorbing mat 200 to be fixed. In this case, if the length of the above-described loop is set in accordance with the perimeter of the cross section of the thinnest one of the planned sound absorbing mats 200, no matter what sound absorbing mat 200 is fixed. Since tension is applied to the band material 120, the fixing of the sound absorbing mat 200 to the film material 100 by the band material 120 and the film material main body 110 becomes strong. FIG. 9 shows a case in which the band material 120 of the film material 100 shown in FIG. 1 has elasticity and a somewhat thicker sound absorbing mat 200 is fixed to the film material 100.

It is assumed that the film material 100 is as shown in FIG. Also in this case, the vicinity of both ends of the sound absorbing mat 200 is inserted into the two loops having the same height. Thereby, one sound absorbing mat 200 can be detachably fixed by a pair of loops. This is done for all loops in the pair. By doing so, each of the sound absorbing mats 200 is fixed to the film material 100 while keeping their longitudinal directions substantially horizontal. Further, the fixed sound absorbing mats 200 are arranged side by side in the vertical direction. FIG. 10 shows this state.
Also in this case, the size and the shape of the loop and the size and shape of the cross section of the sound absorbing mat 200 to be used, and the band material 120 having elasticity in the length direction are adopted. What can be done is the same as that described for the film material 100 shown in FIG.

In the above example, a gap is formed between the upper and lower adjacent sound absorbing mats 200 due to the presence of the attachment portion 121 in the film material 120. With respect to the vertical length of the sound absorbing mat 200 when attached to the film material 100, the smaller the length of the gap, the greater the soundproofing effect of the soundproof house. The ratio of the latter to the former is preferably about 0.1 or less. If the ratio is set to this level, the soundproofing effect of this soundproof house can be said to be sufficiently better than the conventional soundproof house.
As a measure for reducing the ratio of the gap to the vertical length of the sound absorbing mat 200, the above-mentioned band material can be configured as shown in FIG. In this case, two film materials 120X and 120Y are attached to the film material main body 110 of the film material 100, respectively. The two band materials 120X are paired and used to fix the same sound absorbing mat 200. The two band members 120Y are paired and used to fix the same sound absorbing mat 200. In this embodiment, the band material 120X is used to fix the odd-numbered sound absorbing mats 200 from the top, and the band material 120Y is used to fix the even-numbered sound absorbing mats 200 from the top.
The band material 120X is fixed to the film material main body 110 only at both ends thereof, and when the sound absorbing mat 200 is fixed to the film material 100, only the portions hidden under the even-numbered sound absorbing mats 200 from the top. is there. On the other hand, the band material 120Y is fixed to the film material main body 110 at both ends thereof and when the sound absorbing mat 200 is fixed to the film material 100, the portion hidden under the odd-numbered sound absorbing mat 200 from the top. Only. In this way, it is not necessary to fix both the film material 120X and the film material 120Y to the film material main body 110 in the gap between the two vertically adjacent sound absorbing mats 200. This makes it possible to reduce the gap.

[Modification 1]
FIGS. 11A and 11B show a front view of the film material 100 according to the first modification and a front view when the sound absorbing mat 200 is attached to the film material 100, respectively. The configuration of the film material 100 is substantially the same as the film material 100 of the first embodiment.
The only difference is that the membrane 100 comprises an auxiliary membrane 130 between two membranes 120 attached to the membrane body 110. When the distance between the pair of band members 120 or the pair of loops described above is large, the auxiliary band member 130 assists the fixing of the sound absorbing mat 200 by the pair of loops to be stronger.
The configuration of the auxiliary film material 130 is the same as that of the film material 120, and the auxiliary film material 130 has the auxiliary film material 130 and the film material body 110 at the same height at both ends and the film material 120. An attachment portion 131 to be connected is provided.
The method of using the film material 100 is substantially the same as that of the first embodiment. However, in the first embodiment, the sound-absorbing mat 200 in which the vicinity of both ends is fixed to a pair of loops is used in the case of the film material 100. Is fixed not only by a pair of loops but also by a loop formed by the auxiliary band material 130 and the film body 110 between them.
Note that it is obvious that the first modification can be applied to the other film materials 100 described in the first embodiment with reference to FIGS. 2 and 9 in addition to the film material 100 described in FIG. This also applies to the second modification.

[Modification 2]
FIG. 12 is a front view showing a case where the sound absorbing mat 200 is attached to the film material 100 according to the second modification. The configuration of the film material 100 is substantially the same as the film material 100 of the first embodiment.
The only difference is that the film material 100 includes two sets of two film materials 120 attached to the film material main body 110 in the width direction of the film material main body 110. The two sets of two band members 120 can have exactly the same configuration, and this is the case with the second modification. However, it is not necessary that the two sets of two film materials 120 have exactly the same configuration. For example, it is possible to change the interval between the two film materials 120 in each set, the width of the film material 120, the position of the mounting portion 121, and the like.
The method of using the film material 100 is substantially the same as that of the first embodiment. Also in the modified example 2, similarly to the case of the first embodiment, the sound absorbing mat 200 is fixed to the pair of loops near both ends thereof. The difference between the second modification and the first embodiment is that this is performed for each of the two sets of the two band members 120.

<< 2nd Embodiment >>
The film material 100 according to the second embodiment will be described with reference to FIGS.
The film material 100 of the second embodiment is also a film material 100 that can be used to construct a soundproof house, and includes the same film material main body 110 as in the first embodiment.
The difference between the film material 100 of the second embodiment and the film material 100 of the first embodiment is that the film material 100 of the second embodiment does not include the band material 120 provided in the film material 100 of the first embodiment. That is the point. The film material 100 of the second embodiment includes a string 150 instead of the film material 120 of the film material 100 of the first embodiment. The string 150 is used for detachably attaching the sound absorbing mat 200 to the film material 100, similarly to the band material 120 in the first embodiment.
The string 150 is made of a flexible material and does not prevent winding or folding of the membrane material 100 to which the string 150 is attached.
The base end of the string 150 is fixed to a position corresponding to the center of the attachment portion 121 of the film material 120 in the film material 100 of the first embodiment, although not limited thereto. In FIG. 13, two strings 150 existing at the same height are a pair of two, and they fix one end of one sound absorbing mat 200 in the longitudinal direction. The length of the string 150 is longer than the circumference of the cross section of the sound absorbing mat 200.
This film material 100 is used in a state where it is fixed to the pillar 1 and the roof material 3 so as to cover the column 1 and the roof material 3 of the soundproof house, similarly to the film material 100 of the first embodiment.
A method for attaching the sound absorbing mat 200 to the film material 100 is as follows. To attach the sound absorbing mat 200 to the membrane material 100 of the second embodiment, the upper end of the sound absorbing mat 200 is aligned with the upper end of the string 150, and the string 150 is caused to make a round of the sound absorbing mat 200 in the cross-sectional direction. Then, by joining the vicinity of the distal end of the string 150 and the vicinity of the base end of the string 150, both ends of the sound absorbing mat 200 or the vicinity thereof are fixed by a loop made of the string 150. By performing this with both the pair of strings 150, both ends of the sound absorbing mat 200 or the vicinity thereof can be detachably fixed with the pair of strings 150. In FIG. 14, reference numeral 151 denotes a knot. However, the fixing of the distal end and the proximal end of the string 150 is not performed by tying, but by using an appropriate metal fitting or the like, the working efficiency is improved.
By repeating this for all of the pair of strings 150, each sound absorbing mat 200 is fixed to the film material 100 while keeping their longitudinal directions substantially horizontal. Further, the fixed sound absorbing mats 200 are arranged side by side in the vertical direction.

The head 191A is circular, though not limited to this, and the needle 191 is fixed at its center, and has a larger diameter than the needle 191B.
In the third embodiment, the sound absorbing mat has the needle 191B of the pin 191 penetrating the film material 190 from the outside of the film material 190, and the needle portion 191B penetrating the film material 190 makes the longitudinal side substantially horizontal. The film material 190 and the sound absorbing mat 200 are fixed by further penetrating an appropriate portion of the sound absorbing mat 200 (in this embodiment, four corners of the sound absorbing mat 200 are not limited thereto).
Although not limited to this, in this embodiment, the needle portion 191B of the pin 191 protruding from the inner surface of the sound absorbing mat 200 is bent, for example, by about 90 ° so that the sound absorbing mat 200 is more securely fixed to the film material 190. It is assumed that. Further, although not limited to this, in this embodiment, the needle portion 191B of the pin 191 protruding from the inner surface of the sound absorbing mat 200 is bent after the washer 192 is sunk into the needle portion 191B, This further secures the sound absorbing mat 200 to the film material 190.
Although gaps are provided above and below each sound absorbing mat 200 in FIG. 15, it is of course possible to eliminate such gaps.
