Description

The present invention relates to wall technology.

Conventionally, wall technology has been publicly known, for example as described in Patent Document 1.

Patent Document 1 describes a load-bearing wall that is constructed by covering a wall base material such as studs with an interior material such as plasterboard.

The above-mentioned load-bearing walls are expected to be used, for example, as walls separating the rooms in an apartment building. In this case, the load-bearing walls are required to have sound insulation properties.

JP 2020-105810 A

The present invention was made in consideration of the above situation, and the problem it aims to solve is to provide a wall that can improve sound insulation performance.

The problem that the present invention aims to solve is as described above, and the means for solving this problem will be explained next.

In other words, in claim 1, the wall comprises a plurality of columns arranged at a predetermined interval, braces connecting the plurality of columns, a panel covering both the front and rear sides of the columns and the braces so as to form the front and rear sides of the wall, and a sound-insulating material having sound-insulating properties, which is arranged in a space partitioned by the columns and the braces when viewed in the front and rear direction and by the panel when viewed in the up and down direction.

In claim 2, the system includes a stud that is arranged between the plurality of columns and to which the panel is fixed, the stud has a cutout portion formed to avoid interference with the brace, and the space is defined by the columns, the brace, and the stud when viewed in the front-to-rear direction.

In claim 3, the sound-proofing material is not placed in front of or behind the brace.

In claim 4, the front-to-back dimension of the brace is at least half the front-to-back dimension of the space.

In claim 5, the front-to-rear dimension of the sound-proofing material is the same as the front-to-rear dimension of the space.

The effects of the present invention are as follows:

In claim 1, sound insulation performance can be improved.

In claim 2, the soundproofing material can be used to prevent the wall thickness from expanding in walls with studs.

In claim 3, the soundproofing material can prevent the wall thickness from expanding.

In claim 4, the front-to-rear dimension (thickness) of the brace is made relatively large, making it easier for the brace to hold the sound-proofing material.

In claim 5, the front-to-rear dimensions (thickness) of the sound-proofing material can be secured, improving sound-proofing performance.

The following describes the configuration of a partition wall 1 according to one embodiment of the present invention, using Figures 1 to 3. In addition, the following description defines the front-rear direction, left-right direction, and up-down direction based on the arrows in the figures.

Partition wall 1 separates the boundaries between each dwelling unit in an apartment building (tenement house, condominium, etc.). Partition wall 1 has fire resistance and sound insulation properties. Partition wall 1 is placed with the wall surface facing forward and backward. Partition wall 1 is formed by providing a surface material 40 (described later) in front of and behind a lightweight steel frame base (studs 30, described later, etc.). Partition wall 1 comprises columns 10, braces 20, studs 30, surface material 40, filling material 50, and outlets 60.

In Figure 1, the illustration of the panel 40 (underlying panel 41 and overlying panel 42) described below is omitted as appropriate to expose the inside of the partition wall 1. Also, in Figure 2, each part is shown diagrammatically, for example, the cross section of a hollow member is shown as solid for convenience.

The columns 10 support the partition wall 1. The columns 10 are provided between the structure of the lower floor (e.g., the foundation or the beams of the lower floor) and the structure of the upper floor (e.g., the beams of the upper floor). The columns 10 are formed of hollow steel columns such as square steel pipes. Multiple columns 10 are provided at predetermined intervals. In this embodiment, the length dimension (vertical dimension) of the columns 10 is formed to be approximately 2700 mm.

The brace 20 improves the strength of the partition wall 1. The brace 20 is arranged to connect adjacent columns 10. The brace 20 has a main body 21 that extends diagonally and a connection part 22 that connects the end of the main body 21 to the column 10.

As shown in FIG. 1, the brace 20 has a pair of main body parts 21 that extend from the vertical center of the column 10 on one side to the upper end side and lower end side of the column 10 on the other side. A common connection part 22 to which one end of the pair of main body parts 21 is connected is fixed to the vertical center of the column 10 on one side. In addition, a connection part 22 to which the other end of the pair of main body parts 21 is connected is fixed to the upper end side and lower end side of the column 10 on the other side.

In this way, the brace 20 is formed in a roughly K-shape (K-type) when viewed from the front. In the illustrated example, a pair of braces 20 is arranged symmetrically in each of the spaces (two spaces) between the three columns 10. In the above example, a K-shaped brace 20 is used, but instead of this, a roughly N-shaped (N-type) brace 20 when viewed from the front may be used.

In this embodiment, the brace 20 is a buckling restraint brace in which the main body 21 is formed from a long steel core material and a restraining material that covers the core material to restrain the buckling of the core material. The main body 21 is formed so that the outer shape is rectangular in cross section (see Figure 2).

In the following, the area of the partition wall 1 between the columns 10 where the braces 20 are arranged will be referred to as the "stress-bearing section," and the area between the columns 10 where the braces 20 are not arranged will be referred to as the "non-stress-bearing section." As shown in Figures 1 and 2, in this embodiment, the boundary between the "stress-bearing section" and the "non-stress-bearing section" of the column 10 is located in the center of the column 10 in the left-right direction.

The studs 30 are partitions installed between the columns 10. The studs 30 form the base material for attaching the panel 40 described below. The studs 30 are formed from a member (lightweight steel frame (LSG)) made by bending a metal plate with a thickness of, for example, about 0.5 mm to 0.8 mm into a roughly C-shaped cross section. The studs 30 are fixed to the structures on the upper and lower floors of the building via runners 2, which are members that extend in the left-right direction. In this embodiment, two studs 30 are placed between the columns 10.

As shown in Figures 1 and 2, the studs 30 arranged in the load-bearing section have cutouts 31 formed to avoid interference with the main body 21 of the brace 20. The cutouts 31 are formed so as to be recessed toward the rear. The cutouts 31 are formed in two locations for each stud 30. The cutouts 31 are formed to have a length dimension of 700 mm or less.

The face material 40 constitutes the wall surface of the partition wall 1. The face material 40 is fixed to the front and rear surfaces of the studs 30. The face material 40 is made of gypsum board. The gypsum board may be one that contains glass fiber or the like (reinforced gypsum board) to enhance fire resistance. The face material 40 is fixed using fasteners such as staples and screws. In addition to staples, adhesive may also be used for fixing. The face material 40 may have a height (vertical dimension) of about 1820 mm and a width (horizontal dimension) of about 606 mm to 1210 mm. A plurality of face materials 40 are arranged to cover the columns 10, braces 20, and studs 30.

The surface material 40 includes an underlay surface material 41 that is placed on the base, and an overlay surface material 42 that is placed to cover the underlay surface material 41. The surface material 40 is placed so that the joints between adjacent underlay surface materials 41 and the joints between adjacent overlay surface materials 42 do not overlap front to back (seams are offset). The joints (end joints) of the surface material 40 are treated with an end joint treatment material (not shown). As the end joint treatment material, airtight tapes (airtight sheets) such as acrylic airtight waterproof tape and aluminum vapor deposition tape, and sealants such as silicone can be used.

As shown in Figures 1 and 2, an internal space A is formed between the front and rear panel members 40 (underlayment panel members 41) in the partition wall 1. The internal space A is partitioned (divided) into multiple spaces by the front and rear underlayment panel members 41, columns 10, braces 20, and studs 30.

In this embodiment, the front-to-rear dimension X of the internal space A is approximately 100 mm (see FIG. 2). In this embodiment, the front-to-rear dimension of the stud 30 is approximately the same as the front-to-rear dimension X. The front-to-rear dimension of the column 10 is smaller than the front-to-rear dimension X. In this embodiment, the front-to-rear dimension of the main body 21 of the brace 20 is more than half the front-to-rear dimension X (for example, 65 mm).

The filler 50 shown in Figures 1 and 2 is filled into the internal space A. The filler 50 is made of a material that has fire resistance and soundproofing (sound absorption) properties. As the filler 50, artificial mineral fibers such as rock wool, glass wool, and alkaline earth silicate (AES) wool, steel plate, etc. can be used. The filler 50 is formed into an approximately plate shape. The filler 50 includes a non-load-bearing part side filler 51, a load-bearing part side filler 52, and a column front filler 53.

The non-load-bearing portion side filler 51 is filled into the internal space A in the non-load-bearing portion of the partition wall 1. Specifically, the non-load-bearing portion side filler 51 fills the space partitioned by the front and rear underlayment panel 41, the column 10, and the stud 30 in the non-load-bearing portion. The non-load-bearing portion side filler 51 is processed into a shape that corresponds to the shape of the partitioned space (rectangular in front view) when viewed from the front. The thickness dimension (front-to-back dimension) of the non-load-bearing portion side filler 51 is formed to be approximately the same as the front-to-back dimension X.

The load-bearing section side filler 52 is filled into the internal space A in the load-bearing section of the parting wall 1. Specifically, the load-bearing section side filler 52 fills the space in the load-bearing section that is partitioned by the front and rear underlayment panel 41, the column 10, the brace 20, and the stud 30. That is, the load-bearing section side filler 52 fills the space that is further partitioned (divided) by the brace 20 into a rectangular space in front view that is roughly the same as the non-load-bearing section. The load-bearing section side filler 52 is processed into a shape that corresponds to the partitioned space in front view. The thickness dimension (front-to-back dimension) of the load-bearing section side filler 52 is formed to be roughly the same as the front-to-back dimension X.

In this embodiment, the non-load-bearing section side filler 51 and the load-bearing section side filler 52 are one sheet (one layer) of filler. In this embodiment, no filler is provided before or after the brace 20. Instead of this, filler may be provided to cover the front and rear of the brace 20. In this case, a flat brace 20 with a relatively small thickness (body 21 in a plate shape) may be used.

The pre-column filler 53 is filled in the gap (gap between the column 10 and the underlay surface material 41) formed in the front and rear of the column 10 in the internal space A. The pre-column filler 53 is attached to the front and rear of the column 10 so as to cover almost the entire front and rear of the column 10. In the example shown in FIG. 2, the width dimension (left and right dimension) of the pre-column filler 53 is formed to be approximately the same as the width dimension of the column 10. Alternatively, the width dimension of the pre-column filler 53 may be formed to be larger than the width dimension of the column 10. In this case, the pre-column filler 53 may be fixed to the studs 30 on both the left and right sides of the column 10 so as to straddle the column 10.

The outlet 60 shown in Figures 3 and 7(a) constitutes an outlet from which electricity can be extracted. The outlet 60 is located on the lower end side of the partition wall 1. The outlet 60 is formed in the panel 40 and is attached to an opening that communicates with the internal space A. Multiple outlets 60 (four on each side in the illustrated example) are located on the front and rear surfaces of the partition wall 1 (upper panel 42) with spaces between them in the left-right direction.

In this embodiment, the number of outlets 60 is set to four or less in a predetermined range on one side of the partition wall 1. Here, the "predetermined range" may be a range defined by the width dimension of the partition wall 1 (e.g., about 3680 mm) or an area (e.g., about ¹⁰ m2). The "predetermined range" may be the entire one side of the partition wall 1. In this embodiment, the total area of the openings (four in the illustrated example) formed on one side of the partition wall 1 is set to 0.045 ^m2 or less. In this embodiment, two or less outlets 60 are provided for one gypsum board constituting the overlay surface material 42.

In this embodiment, the outlets 60 located at the front and rear of the partition wall 1 are arranged so that they do not overlap each other front to back. In this embodiment, the front and rear outlets 60 are arranged with a gap between them that is greater than the width dimension (left to right dimension) of the outlets 60. In this embodiment, the widthwise gap Y (narrowest gap) between the front and rear outlets 60 is set to approximately 165 mm (see FIG. 7(a)). In this embodiment, the outlets 60 are arranged so that one of the front and rear outlets 60 is located between multiple studs 30 adjacent to each other in the wall width direction (see FIG. 1). In this embodiment, the outlets 60 are arranged so that the front and rear outlets 60 are alternately located (staggered) in the left to right direction.

In order to install the outlets 60, it is necessary to form an opening in the panel 40. Therefore, if the front and rear outlets 60 are arranged so as to overlap, there is a risk that the sound insulation performance will decrease in the overlapping area. In contrast to this, by arranging the front and rear outlets 60 so that they do not overlap, it is possible to suppress the decrease in sound insulation performance. In addition, in this embodiment, the sound insulation performance can be further improved by making the distance between the front and rear outlets 60 in the wall width direction relatively large.

The above describes the partition wall 1 according to this embodiment. Note that the specific values given in the above description are merely examples and can be changed as desired. Also, the presence or absence, type, dimensions, number, etc. of the components given in the above description are merely examples and the presence or absence, type, etc. of the components can be changed as appropriate.

The above-mentioned parting wall 1 is required to have sound insulation performance based on standards established in a prescribed sound insulation performance evaluation (for example, standards related to Article 30 of the Building Standards Act). The sound insulation performance of the parting wall 1 is determined by the specifications of the parting wall 1. Here, the "specifications of the parting wall 1" refer to the specifications of each member that constitutes the parting wall 1 (presence or absence of each member, material, dimensions, etc.).

The person who designs the parting wall 1 (designer) can determine the specifications of the parting wall 1 depending on the purpose of the room that the parting wall 1 faces. For example, if the parting wall 1 is located on the boundary between two living rooms (such as living rooms), the specifications of the parting wall 1 are determined so that it has a relatively high level of sound insulation performance (such as "operational specifications"). Also, if the parting wall 1 is located on the boundary between two wet areas, the specifications of the parting wall 1 are determined so that it has a minimum level of sound insulation performance.

Below, we will explain the relationship between the specifications of each component that makes up the partition wall 1 and the sound insulation performance using Figures 4 to 8.

Figure 4 is a table showing the relationship between the specifications of the filler material 52 on the load-bearing section side and sound insulation performance. More specifically, the table in Figure 4 shows the relationship between the proportion of the area of the filler material 52 on the load-bearing section side of the parting wall 1 when viewed from the front and sound insulation performance. Figure 4 compares a test specimen with "100% filler material" and a test specimen with "92% filler material".

Here, "100% filled with filler" means that the area of the load-bearing section side filler 52 in a front view is 100% of the total area of the load-bearing section of the partition wall 1. In other words, in the test specimen with "100% filled with filler", the entire load-bearing section, including the brace 20, is covered with the load-bearing section side filler 52.

"92% filled with filling material" indicates that the area of the load-bearing section side filling material 52 in a front view is 92% of the total area of the load-bearing section of the partition wall 1. In this embodiment, no filling section (load-bearing section side filling material 52) is provided at the front or rear of the brace 20, so that the area of the load-bearing section side filling material 52 is 92% of the total area of the load-bearing section. The above test specimens are generally similar in other conditions, except for the proportion of the area of the load-bearing section side filling material 52.

The table in Figure 4 compares the sound transmission loss (dB) of each test specimen for multiple frequencies (125 Hz, 250 Hz, 500 Hz, 1000 Hz, 200 Hz). In the table above, the sound transmission loss (dB) of the test specimen "filled with 100% filler" at each frequency is set as the benchmark (BM), and the sound transmission loss (dB) of the test specimen "filled with 92% filler" is shown as the difference from the benchmark. A positive value for the difference indicates relatively high sound insulation performance, and a negative value indicates relatively low sound insulation performance.

As shown in the table in Figure 4, the sound transmission loss (dB) of the test specimen with "92% filling material" was -0.9 dB at 125 Hz, -0.5 dB at 250 Hz, 0 dB at 500 Hz, +0.1 dB at 1000 Hz, and -0.1 dB at 200 Hz. From the results in the above table, it was found that when "92% filling material" was used (no filling section was provided at the front and rear of the brace 20), the sound insulation performance was slightly reduced, but the difference from the benchmark ("100% filling material") was less than 1 dB, which is not a significant impact.

Figure 5(a) is a table showing the relationship between the specifications (material and thickness) of the column front filling material 53 and the sound insulation performance. Figure 5(a) compares the test specimens with "no sound insulation technology", "AES", "RW10 thickness", "RW8 thickness", and "steel plate".

Here, "without sound insulation technology" means that no pre-column filler 53 is provided on the columns 10. "AES" means that a pre-column filler 53 of alkaline earth silicate (AES) wool with a density of 130 kg/m ³ and a thickness of 12.5 mm is provided. "RW10 thickness" means that a pre-column filler 53 of rock wool with a density of 80 kg/m ³ and a thickness of 10 mm is provided. "RW8 thickness" means that a pre-column filler 53 of rock wool with a density of 80 kg/m ³ and a thickness of 8 mm is provided. "Steel plate" means that a pre-column filler 53 of steel plate with a thickness of 0.5 mm is provided.

Of the test specimens, the "AES", "RW10 thickness" and "RW8 thickness" test specimens have pre-column filler 53 formed to roughly the same dimensions as the width of the column 10, fixed directly to the column 10. Also, the "steel plate" test specimen has pre-column filler 53 formed to be larger than the width of the column 10, fixed to studs 30 on both the left and right sides of the column 10 so as to straddle the column 10. Also, the other conditions of each of the above test specimens are roughly the same.

Here, if the pillar 10 is hollow, the sound of the wavelength corresponding to the length of the pillar 10 is amplified and radiated due to the resonance phenomenon, and the sound insulation performance of that frequency is reduced. In this embodiment, the length dimension of the pillar 10 (2700 mm) roughly matches the wavelength of the frequency of 125 Hz, so the sound insulation performance in the frequency band around 125 Hz is likely to decrease. For this reason, in the following explanation, verification will be performed focusing on the sound insulation performance at 125 Hz, which produces the most unfavorable results. Note that in the above table, the sound transmission loss (dB) of the test specimen without sound insulation technology at 125 Hz is set as the benchmark (BM), and the sound transmission loss (dB) of the other test specimens is shown as the difference from the benchmark.

As shown in the table in Figure 5(a), the sound transmission loss (dB) of the "AES" test specimen was 2.7 dB, the sound transmission loss (dB) of the "RW10 thickness" test specimen was 2.1 dB, the sound transmission loss (dB) of the "RW8 thickness" test specimen was 1.7 dB, and the sound transmission loss (dB) of the "steel plate" test specimen was 2.0 dB.

From the results in the above table, it was verified that when the column pre-filler 53 is provided on the column 10, the sound insulation performance in the 125 Hz frequency band can be improved. In addition, it was verified that the greater the density and thickness of the column pre-filler 53, i.e., the heavier it is, the higher the sound insulation performance. Here, in the above results, the "AES" and "RW10 thickness" test specimens have higher sound insulation performance than the heaviest "steel plate" test specimen. From this, it was found that the sound insulation performance can be improved more efficiently by directly fixing the artificial mineral fiber column pre-filler 53 to the column 10 than by indirectly installing the steel plate column pre-filler 53 to the column 10.

In the above example, as shown in FIG. 2, a front-column filler 53 is provided on the front and rear surfaces of the column 10, but the present invention is not limited to the above example. For example, the modified examples shown in FIG. 5(b) and (c) may be used.

Figure 5(b) shows an example in which a filler material 53 is provided around the entire circumference of the pillar 10. This makes it possible to suppress sound radiation caused by resonance and improve sound insulation performance. Figure 5(c) shows an example in which a filler material 53 is filled into the hollow portion of the hollow pillar 10. This makes it possible to suppress resonance and improve sound insulation performance.

Figure 6 is a table showing the relationship between the specifications of the outlets 60 (number, arrangement, etc.) and sound insulation performance. In Figure 6, a comparison is made between a test specimen with "no outlets," a test specimen with "four outlets on one side in a staggered arrangement," a test specimen with "four outlets on one side in the same positions on both sides," and a test specimen with "eight outlets on one side in the same positions on both sides."

Here, "no outlet" means that no outlet 60 is provided on the partition wall 1. In addition, "four locations on one side in a staggered arrangement" means that outlets 60 are provided in four locations on one side of the partition wall 1 in a staggered arrangement, as shown in FIG. 7(a). In addition, "four locations on one side in the same position on both sides" means that outlets 60 are provided in four locations on one side of the partition wall 1 so that they are in the same position on both sides (back to back), as shown in FIG. 7(b). In addition, "eight locations on one side in the same position on both sides" means that outlets 60 are provided in eight locations on one side of the partition wall 1 so that they are in the same position on both sides (back to back), as shown in FIG. 7(c). In addition, each test specimen has a wall thickness of about 150 mm, and the widthwise distance Y (narrowest distance) between the front and rear outlets 60 is set to about 165 mm. The above test specimens are generally the same in other conditions, except for the specifications of the outlets 60.

The table in Figure 6 compares the sound transmission loss (dB) of each test specimen for each frequency (125 Hz, 250 Hz, 500 Hz, 1000 Hz, 200 Hz). Note that in the above table, the sound transmission loss (dB) of the "no outlet" test specimen is set as the benchmark (BM), and the sound transmission loss (dB) of the other test specimens is shown as the difference from the benchmark.

As shown in the table in Figure 6, the sound transmission loss (dB) of the test specimen with "four locations on one side, staggered arrangement" was -1.7 dB at 125 Hz, -0.6 dB at 250 Hz, -1.9 dB at 500 Hz, -4.3 dB at 1000 Hz, and -1.8 dB at 200 Hz. Also, the sound transmission loss (dB) of the test specimen with "four locations on one side, same locations on front and back" was -1.2 dB at 125 Hz, -0.7 dB at 250 Hz, -3.7 dB at 500 Hz, -7.1 dB at 1000 Hz, and -2.1 dB at 200 Hz. Additionally, the sound transmission loss (dB) of the test specimen "eight points on one side, in the same positions on both sides" was -2.7 dB at 125 Hz, -2.1 dB at 250 Hz, -5.8 dB at 500 Hz, -10.2 dB at 1000 Hz, and -3.0 dB at 200 Hz.

From the results in the above table, it was verified that the test specimen with four outlets 60 on one side had better sound insulation performance than the test specimen with eight outlets 60 on one side. Also, even when four outlets 60 were provided on one side, it was verified that the sound insulation performance was particularly high when the outlets 60 were arranged in a staggered pattern.

More specifically, the results of the test specimen with "four outlets on one side, staggered" showed that in the frequency band below 500 Hz, the difference from the benchmark ("no outlets") was less than 2 dB, meaning that there was no significant impact. Furthermore, since human voices are primarily heard in the frequency band between 250 Hz and 500 Hz, providing outlets 60 in a "four outlets on one side, staggered" arrangement reduces the risk of everyday conversation leaking into adjacent rooms.

The results in the table above also show that the test specimen with "four locations staggered on one side" has higher sound insulation performance in the frequency range of 500 Hz to 1000 Hz, where human hearing is sensitive, compared to the test specimens with "four locations staggered on one side" and "eight locations on one side, in the same positions on both sides."

In the above-mentioned example, the outlets 60 are arranged with a space between them in the left-right direction as shown in Fig. 2 and Fig. 7(a), but the present invention is not limited to the above example. For example, the outlets 60 may be arranged with a space between them in the up-down direction as shown in the modified example in Fig. 8.

In the partition wall 1 shown in FIG. 8, the outlets 60 located at the front and rear are also arranged in a staggered pattern so that they do not overlap each other front to back. In this embodiment, the vertical distance Y (narrowest distance) between the front and rear outlets 60 is set to approximately 165 mm. According to the example shown in FIG. 8, for example, of the upper and lower outlets 60, the upper outlet 60 can be used as an outlet for an air conditioner or refrigerator, the middle outlet 60 can be used as an outlet with a light switch, and the lower outlet 60 can be used as an outlet for general home appliances.

As described above, the wall (partition wall 1) according to this embodiment has the following features:
A plurality of pillars 10 arranged at predetermined intervals;
A brace 20 that connects a plurality of the columns 10 together;
A surface material 40 that covers both the front and rear sides of the column 10 and the brace 20 in the front-rear direction so as to form the front and rear surfaces of the wall surface;
A sound-insulating material (strength-bearing-portion-side filler 52) having sound-insulating properties is disposed in a space (internal space A in the strength-bearing portion) that is partitioned by the columns 10 and the braces 20 when viewed in the front-rear direction and by the panel 40 when viewed in the up-down direction;
It is equipped with the following.

This configuration can improve sound insulation performance. That is, by placing the sound insulation material (load-bearing section side filler 52) in the space partitioned by the pillar 10 and the brace 20 when viewed in the front-to-back direction, it becomes easier to ensure the thickness of the sound insulation material (load-bearing section side filler 52), and sound insulation performance can be improved. Also, unlike, for example, placing sound insulation material to cover the front and rear of the brace 20, it is possible to suppress the wall thickness from expanding. Also, it is possible to use one sheet (one layer) of sound insulation material (load-bearing section side filler 52), which improves workability.

In addition, the wall (partition wall 1) according to this embodiment is
The method further comprises providing a stud (30) disposed between the plurality of columns (10) and to which the surface material (40) is fixed;
The studs (30) are
A notch 31 is formed to avoid interference with the brace 20,
The space (internal space A in the load-bearing portion) is
When viewed in the front-to-back direction, it is partitioned by the columns 10, the braces 20, and the partition walls (studs 30).

This configuration makes it possible to prevent the soundproofing material (load-bearing section side filler 52) from causing the wall thickness to expand in a wall (partition wall 1) that has studs (studs 30).

In addition, the wall (partition wall 1) according to this embodiment is
The sound insulation material (load-bearing portion side filler 52 ) is not arranged in front of or behind the brace 20 .

This configuration can prevent the wall thickness from expanding due to the sound insulation material (load-bearing section side filler 52). It also reduces the burden of work. That is, for example, if sound insulation material is arranged to cover the front and rear surfaces of the brace 20, the thickness of the sound insulation material will be added to the thickness of the brace 20, and the thickness of the member provided in the internal space A of the partition wall 1 will be relatively large, which may cause the wall thickness to expand. On the other hand, in the partition wall 1 according to this embodiment, the sound insulation material (load-bearing section side filler 52) is provided only in the internal space A in the load-bearing section, and no sound insulation material (load-bearing section side filler 52) is provided in front of or behind the brace 20, so that it is possible to prevent the wall thickness from expanding.

The front-to-rear dimension of the brace 20 is at least half the front-to-rear dimension X of the space (internal space A in the load-bearing section).

By configuring it in this way, the front-to-rear dimension (thickness) of the brace 20 can be made relatively large, making it easier for the brace 20 to hold the sound-proofing material (load-bearing section side filler material 52).

The front-to-rear dimension of the sound insulation material (load-bearing section side filler 52) is the same as the front-to-rear dimension X of the space (internal space A in the load-bearing section).

By configuring it in this way, the front-to-rear dimension (thickness) of the sound-proofing material (load-bearing section side filler 52) can be secured, improving sound-proofing performance.

In addition, the wall (partition wall 1) according to this embodiment is
A plurality of pillars 10 arranged at predetermined intervals;
A surface material 40 that covers the column 10 so as to form the front and rear surfaces of the wall surface;
Between the face material 40 and the column 10, a sound-insulating material (column front filler 53) is fixed to the column 10 so as to cover the entire front and rear surfaces of the column 10 and has sound-insulating properties;
It is equipped with the following.

This configuration can improve sound insulation performance. In other words, by fixing the sound insulation material (pillar front filler 53) to the pillar 10 so as to cover the entire front and rear surfaces of the pillar 10, sound insulation performance can be improved.

In addition, the sound insulation material (pillar front filling material 53) is,
It is formed in the form of a tape that is attached to the entire front and rear surfaces of the pillar 10.

This configuration can further improve sound insulation performance. In other words, by attaching the column front filler 53 to the entire front and rear surfaces of the column 10, sound insulation performance can be further improved.

The width of the soundproofing material (pillar front filling material 53) is the same as the width of the pillar 10.

By configuring it in this way, the width dimension of the soundproofing material (pillar front filling material 53) can be minimized.

In addition, the sound insulation material (pillar front filling material 53) is,
It is made of artificial mineral fibers and has a density of 80 kg/ ^m3 or more.

By configuring it in this way, it is possible to further improve the sound insulation performance. In other words, by making the density of the sound insulation material (pillar front filling material 53) made of artificial mineral fiber relatively large, it is possible to further improve the sound insulation performance.

The front-to-rear dimension of the soundproofing material (pillar front filling material 53) is 10 mm or more.

By configuring it in this way, it is possible to further improve the sound insulation performance. In other words, by making the front-to-back dimension (thickness dimension) of the sound insulation material (pillar front filling material 53) made of artificial mineral fiber relatively large, it is possible to further improve the sound insulation performance.

In addition, the wall (partition wall 1) according to this embodiment is
A plurality of pillars 10 arranged at predetermined intervals;
A surface material 40 that covers the front and rear surfaces of the column 10 so as to form the front and rear surfaces of the wall surface;
A plurality of outlets 60 are arranged at intervals in the wall width direction on each of the front and rear panel members 40;
Equipped with
The plurality of outlets 60 include
When viewed in the front-rear direction, the outlets 60 on the front side and the outlets 60 on the rear side are arranged so as not to overlap each other.

By configuring in this way, it is possible to improve sound insulation performance. That is, when installing the outlet 60 on the wall, it is necessary to form an opening in the panel 40. Therefore, if the front outlet 60 and the rear outlet 60 are installed so as to overlap, there is a risk that the sound insulation performance will decrease in the overlapping portion. In contrast to this, by arranging the front outlet 60 and the rear outlet 60 so that they do not overlap, it is possible to improve sound insulation performance.

The distance between the front outlet 60 and the rear outlet 60 in the wall width direction is greater than the width dimension of the outlet 60.

This configuration can further improve sound insulation performance. In other words, by making the distance between the front and rear outlets 60 in the wall width direction relatively large, sound insulation performance can be further improved.

The front outlets 60 and the rear outlets 60 are arranged in a staggered pattern.

By configuring it in this way, the outlets 60 in front of and behind the outlet 60 can be arranged in a staggered pattern, further improving sound insulation performance.

In addition, the wall (partition wall 1) according to this embodiment is
The method further comprises the steps of: providing a plurality of studs (studs 30) disposed between the plurality of columns (10) and to which the surface material (40) is fixed;
Between a plurality of studs (studs 30) adjacent to each other in the width direction of the wall, one of the front outlets 60 and the rear outlets 60 is disposed.

By configuring it in this way, the distance between the front and rear outlets 60 in the wall width direction can be made relatively large, further improving sound insulation performance.
