Description

TECHNICAL FIELD The present invention relates to a method of constructing a sound absorbing plate and an actual member used therefor.

In the spaces (public spaces) where we live every day, such as offices, shops, schools, and hospitals, there are many complaints about the sound environment, such as "the surroundings are noisy and it is difficult to hear the sound of the phone" and "the voice echoes and it is difficult to hear the lecture". i have a lot of problems. Alternatively, there is a demand for providing a soundproof space for enjoying music at home.

For the purpose of improving such sound environment problems, the walls and ceilings in the room are built with sound absorbing structures in advance, and interior materials called "sound absorbing boards" are attached to the walls and ceilings of the rooms to create a sound absorbing structure after the fact. It is common practice to build

When constructing walls and ceilings with a sound-absorbing structure in advance, generally, at the construction site, the base is assembled with a wooden base or a light-weight steel base, filled with sound-absorbing materials such as glass wool or rock wool, and the surface is smoothed. It can be constructed by finishing with a perforated plate. When part of the energy of the sound incident on the wall surface or ceiling passes through the holes of the perforated plate on the surface, the sound is absorbed by the sound absorbing material. In other words, although the structure of walls and ceilings ensures sound absorption performance, large-scale construction work is required on-site, which is time-consuming and results in unevenness in finish and performance.

On the other hand, when a sound absorbing board is attached to the construction surface to construct a sound absorbing structure after the fact, a low-density soft back surface material and a high-density hard surface material are bonded together to form a laminated board. It can be constructed by attaching a board to the construction surface. The sound absorbing plate utilizes the principle of a Helmholtz resonator, and a plurality of parallel grooves are formed in the surface of the backing material in the longitudinal direction, forming an air layer. The surface material is provided with a large number of sound absorbing holes aligned with the grooves at regular intervals. A part of the sound energy incident on the sound absorbing plate passes through the sound absorbing holes and is absorbed by vibrating in the grooves, which are air layers.

When installing such a sound absorbing board on a wall surface or ceiling (hereinafter referred to as "construction surface"), apply joint tape to the joints, sandwich spacers, etc., and then perform panel construction as necessary. The spacer was removed by hand, or caulking was applied on the spacer, which was very troublesome (opening joint construction method). In order to reduce the time and effort involved, there is a method of constructing the panel by applying “aijakuri processing” to the soft material and hard material parts at the ends of the sound absorbing plate, but in that case, the soft material is not applied to the joints. There was a risk that the soft material would be exposed, lack strength, or be damaged during construction, making construction difficult. As another construction method, there is also known a method in which female joints (concave grooves) are provided in the soft member portion at the end of the sound absorbing plate, and the female joints of adjacent panels are joined by joints (Patent Documents 1 and 2). ).

JP-A-03-28450 JP-A-09-317080

In the above case, when this sound absorbing board is used as a wall material (ceiling material), the female part of the other panel is attached to the vacant male part of the sound absorbing board that has already been installed on one side of the sound absorbing board. In order to insert the fruit, the other sound absorbing plate is lightly inserted in a state in which it is inclined at a shallow angle with respect to the sound absorbing plate that has already been installed, and then it is turned so that it becomes horizontal from this state, and then it is inserted and joined. was required. In such a construction method, an excessive force is applied to the soft material portion of the other sound absorbing plate on the fitting side where the pistil is dug, and this portion may be damaged. Moreover, since such construction requires time and effort, there is also a problem of poor workability.

The present invention has been made in view of such conventional problems, and is a sound absorbing plate that is easy to attach to a construction surface, has a good appearance, and does not damage the soft and fragile back material during actual bonding. An object of the present invention is to provide a method and an actual member used in the construction method.

According to the invention described in claim 1, "the backing material 2 attached to the construction surface W is composed of a soft material, the surface material 3 laminated on the backing material 2 is composed of a hard material, and the female nut 6 is the back surface. A real member 10 formed on the side surface of the material 2 and used by interposing between the adjacent sound absorbing plates 1A and 1B,
The actual member 10 is
a bar-shaped actual member main body 12;
and a male and female member 14 provided on one side surface 12a of the actual member main body 12 and inserted into a female member 6 formed on one side surface of the sound absorbing plate 1A,
The other side surface 12b of the actual member main body 12 is formed flat.

The invention described in claim 2 relates to a method for constructing the sound absorbing plate 1 using the actual member 10 described in claim 1,
"A method for installing a sound absorbing board 1 for attaching the sound absorbing board 1 according to claim 1 to a construction surface W,
Attaching the first sound absorbing plate 1A to the construction surface W,
The male member 14 of the solid member 10 is inserted from the side into the female member 6 formed on the side surface of the first sound absorbing plate 1A, and after that,
The side surface of the second sound absorbing plate 1B is pressed against the construction surface W while being placed along the other side surface 12b of the actual member main body 12, which is a flat surface.

In these inventions, the nut is formed only on one side surface of the actual member, and the other side surface is flat. Therefore, after attaching the actual member to the first sound absorbing plate, when attaching the second sound absorbing plate to the wall surface, it is not necessary to insert the actual member into the female member of the sound absorbing plate. There is no risk of damage to the soft material of In addition, the second sound absorbing plate can be attached to the wall surface simply by pressing the sound absorbing plate parallel to the construction surface while keeping the side surface of the sound absorbing plate along the plane of the actual member.

After the sound absorbing plates are attached to the wall surface, a rod-like actual member is interposed between two adjacent sound absorbing plates. Here, since the front side of the actual member is a joint surface, it is not necessary to fill the joint portion with a caulking agent, and the design is excellent.

It is a perspective view which shows the actual member which concerns on this invention. It is a figure which shows the state which attached the sound-absorbing board to the wall surface. It is a figure which shows the construction method which attaches a sound-absorbing board to a wall surface. It is a front view of a sound-absorbing board. FIG. 5 is a cross-sectional view taken along the line AA in FIG. 4; FIG. 5 is a cross-sectional view taken along the line BB in FIG. 4;

The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a real member 10 according to the present invention.

The actual member 10 is obtained by cutting a corner portion of one side surface of a bar having a rectangular cross section into a rectangular shape over the entire length. The portion left after the cutting is the solid member main body 12, and the portion that is cut off and provided on one side surface 12a of the solid member main body 12 over the entire length in the longitudinal direction is the male member 14. . The other side surface 12b of the actual member main body 12 (the side surface on which the male member 14 is not formed) is a plane (flat surface) without irregularities. A rear surface 12c (a narrow surface from which the nut 14 is scraped off) of the actual member main body 12 is a bonding surface with the construction surface W. As shown in FIG.

In this embodiment, the actual member main body 12 and the male member 14 are integrally formed of a wood fiber board (made by breaking wood into fibers and compressing them with an adhesive). , the actual member main body 12 and the male member 14 are flush with each other. A joint surface 16 is formed on this surface except for the nut 14 .

A decorative sheet 18 is adhered to the integral body of the actual member main body 12 and the male member 14.例文帳に追加The decorative sheet 18 is provided as necessary for decorating the integral body of the actual member main body 12 and the male member 14, and a decorative veneer or decorative paper known in the art can be used. In the embodiment, a wood grain pattern matching the surface pattern of the sound absorbing plate 1 is printed on the surface.

In the present embodiment, the decorative sheet 18 includes the side surface of the male member 14, the front surface (joint surface 16) of the integral body of the male member 14 and the actual member main body 12, the other side surface 12b of the actual member main body 12, and the actual member. Although it is attached so as to cover a part of the back surface 12c of the main body 12, at least a part of the front surface side of the integral body of the actual member main body 12 and the male and female 14, which serves as the joint surface 16, is covered with the decorative sheet 18. (Of course, the entire circumference of the actual member 10 may be covered with the decorative sheet 18).

The thickness t1 of the actual member main body 12 is set to be substantially equal to the thickness of the back surface material 2 of the sound absorbing plate 1, and the thickness t2 of the male member 14 is set to the width of the female member 6 so that it can be inserted into the female member 6 of the sound absorbing plate 1. is set slightly smaller than

The sound absorbing plate 1 is made by laminating a soft material as the back surface material 2 and a hard material as the surface material 3, and it is preferable to use a noncombustible base material for both. However, other materials may be used if noncombustibility is not required.
As the material of the backing material 2, mineral fiber boards such as rock wool, glass wool, slag wool, etc. can be used as nonflammable (porous) materials having excellent sound absorption properties. Wood fiber boards such as insulation boards can also be used if noncombustibility is not required.
As the material of the surface material 3, for example, a volcanic vitreous double layer board defined in the volcanic vitreous double layer board (JIS A5440), a gypsum board, or the like can be used. The surface material 3 is naturally harder than the back material 2 .

On the surface of the backing material 2 constituting the sound absorbing plate 1 (that is, the surface on which the fronting material 3 is laminated), a plurality of grooves 4 are recessed in parallel in the longitudinal direction. is formed with a notch that becomes the female seed 6. Therefore, the female nut 6 is formed on the side surface (four circumferences) of the backing material 2 along the laminated surface of the surface material 3 .

A large number of sound absorbing holes 5 are formed in the surface material 3 at regular intervals in alignment with the grooves 4 in the laminated state, and communicate with the grooves 4 . Not only the length of the recessed groove 4 but also the width of the groove 4 are formed to be large with respect to the sound absorbing hole 5 . Although the sound absorbing holes 5 are round holes in the illustrated embodiment, they are not limited to this, and may be rectangular, polygonal or other irregular shapes in accordance with the design.

A method of attaching the sound absorbing plate 1 to a construction surface W such as a wall surface or a ceiling surface using the actual member 10 configured as described above will be described with reference to FIGS. 2 and 3. FIG.

In FIG. 2, an external corner wall corner material 100 is attached to an external corner with a wall as the construction surface W, and a parting member 200 is attached to an internal corner. A wall corner member 100 for an external corner is formed with a male joint 102 to be inserted into the female joint 6 of the sound absorbing plate 1, and a parting member 200 is formed with a blind collar 202 for hiding the end of the sound absorbing plate 1. It is Here, a method of attaching the sound absorbing plates 1 sequentially from the side of the wall corner material 100 for the external corner to the construction surface W sandwiched between the wall corner material 100 for the external corner and the parting member 200 to be finally installed will be described.

As described above, the exterior corner wall corner member 100 is attached to the exterior corner of the construction surface W, and the entire construction surface W is coated with an adhesive. Then, the side surface of the first sound absorbing plate 1A is aligned with the external corner wall corner material 100, and while being pressed against the construction surface W in this state, this is slid toward the external corner wall corner material 100 side. At this time, the male member 14 of the external corner wall corner member 100 is inserted into the female member 6 on the side of the external corner wall corner member 100 of the sound absorbing plate 1 (or the side surface of the first sound absorbing plate 1A is used as the external corner member). Along the wall corner material 100, the sound absorbing plate 1A is floated to the extent that it does not contact the construction surface W, and the male and female 14 are fitted into the female and female 6 from an oblique direction at a shallow angle with respect to the external corner wall corner material 100. , and then press and bond the sound absorbing plate 1A to the construction surface W). As a result, the first sound absorbing plate 1A is attached to the construction surface W by adhesion while being joined to the external corner wall corner member 100. As shown in FIG.

In this embodiment, an adhesive is used to attach the sound absorbing plate 1A to the construction surface. Alternatively, various methods can be adopted depending on the situation at the site, such as using double-sided tape or finish nails alone.

Next, in the figure, the actual member 10 is placed on the right side of the already bonded sound absorbing plate 1, and while the actual member 10 is pressed against the construction surface W, it slides toward the first sound absorbing plate 1A. Then, the male member 14 of the actual member 10 is fitted into the female member 6 of the sound absorbing plate 1. - 特許庁As a result, the actual member 10 is attached to the construction surface W by adhesion while being fitted in the first sound absorbing plate 1 . At this time, the back surface material 2 of the first sound absorbing plate 1A is not damaged.

Next, one side surface of the second sound absorbing plate 1B is placed along the other flat side surface 12b of the actual member 10, and pressed in parallel to the adhesive-applied construction surface W for bonding. do. Since the other side surface 12b of the solid member 10 is a flat surface, when the second sound absorbing plate 1B is attached to the construction surface W, it is slid laterally to fit the female 6 and the male 14 together. It is very easy to attach the sound absorbing plate 1B because it is only necessary to press the sound absorbing plate 1B parallel to the construction surface W side.

Then, as before, the actual member 10 is attached to the right side of the second sound absorbing plate 1B, and the third sound absorbing plate 1C is attached to the construction surface W. The third sound absorbing plate 1C to be installed last may be cut at the right end in the drawing to match the installation space on the construction surface W (at this time, a space for installing the parting member 200 is left). Finally, by pushing the parting member 200 into the end space of the sound absorbing plate 1C, the mounting of the sound absorbing plate 1 on the construction surface W is completed. The edge of the sound absorbing plate 1C is covered with the flange 202 of the parting member 200. As shown in FIG.

According to this embodiment, only one side surface 12a of the real member 10 is formed with the male and female portions 14, and the other side surface 12b is flat, so that the second (third) sound absorbing plate When attaching 1B (1C) to the construction surface W, the work of inserting the male member 14 of the actual member 10 into the female member 6 of the sound absorbing plate 1B (1C) becomes unnecessary. Therefore, the side surface of the second (third) sound absorbing plate 1B (1C) is aligned with the flat surface side of the actual member 10, and the sound absorbing plate 1B (1C) is pushed in parallel toward the construction surface W, thereby forming the second (third) sound absorbing plate. The attachment of the plate 1B (1C) to the construction surface W is completed, and the construction work becomes very easy. As a result, unlike the prior art, the back surface material 2 of the sound absorbing plate 1, which is fragile, is not damaged by an excessive force when it is fitted into the actual member 10. - 特許庁

A rod-shaped actual member 10 is interposed between the two adjacent sound absorbing plates 1A and 1B, and the actual member 10 functions as a spacer. As with openwork joint construction, the appearance is good. Moreover, since the actual member 10 functioning as a spacer has a joint surface 16 on the front side, there is no need to remove the actual member or fill the joint with a caulking agent as in the conventional openwork joint construction. It is very easy to handle after it is attached to the wall.
In addition, in the above case, the wall surface construction was explained as an example, but the ceiling construction can also be applied.
