Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cross-covered wall structure with excellent soundproofing properties for buildings such as houses.

(Prior Art) In recent years, as buildings such as houses have become more Western-style and diversified, interior walls and other interior surfaces are increasingly being covered with decorative cloth.

In addition, there has been a great deal of interest in the soundproofing properties of not only piano rooms, children's rooms, audio rooms, etc. in homes, but also other buildings.

By the way, the conventional cross-covering finish is achieved by fixing a base material such as plywood or gypsum board to the wall structure such as columns, studs, and rims, and pasting decorative cloth on the surface. I was worried.

(Problem to be solved by the invention) However, with the above-mentioned configuration, sound absorption and
The sound insulation properties were poor, and the desired sound insulation effect could not be sufficiently achieved.

On the other hand, fiberboards such as soft fiberboards are well known as materials with excellent sound absorption properties, but these fiberboards, especially soft fiberboards, tend to absorb and dissipate moisture and moisture depending on the surrounding environment. The fiberboard itself has the property of expanding and contracting as this absorption and dissipation occurs. For this reason, when such fiberboard is fixed to the wall structure as a base material as described above and a decorative cloth is attached to the fiberboard surface with glue, the fiberboard will deteriorate over time after installation. Due to the expansion and contraction of the decorative cloth, gaps may be created at the joints of the decorative cloth, exposing the fiberboard substrate, which can significantly reduce the appearance of the decorative cloth.Also, the adhesiveness of the decorative cloth to the surface of the fiberboard is poor. have.

Therefore, in view of this, the present invention uses a suitable composite board as the base material as described above, and performs sound absorption and sound insulation treatment and processing on the front and back surfaces of the composite board, thereby achieving good sound absorption performance. The purpose of the present invention is to provide a wall structure that is capable of exhibiting an excellent soundproofing effect by combining soundproofing and soundproofing performance, and that can also be finished with a cross-covered surface with good adhesion and that can be maintained beautifully without creating gaps. .

(Means and effects for solving the problem) In order to achieve this purpose, the configuration of the present invention is as follows:
A composite board consisting of a fiberboard, a surface material such as plywood bonded to the surface of the fiberboard, and a sound-insulating sheet-like material bonded to the back surface of the fiberboard is placed on the pillars, studs, and other wall structures, and the above-mentioned A base material having a large number of semi-through holes extending from the surface of the surface material to at least the surface of the fiberboard is installed with the surface material facing up, and the entire surface of the surface material including the hole openings on the surface of the surface material is attached. It is made by pasting a makeup cloth to cover the area. As a result, in addition to the sound absorbing properties of the fiberboard in the composite board as the base material, the numerous semi-through holes on the front surface provide a sound absorbing effect, and the sound insulating sheet material on the back surface further enhances the sound insulating effect. The surface layer material allows for a beautiful cross-covered finish with good adhesion.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 shows a base material A in a wall structure which is an embodiment of the present invention, 1 is a composite board constituting the base material substrate, and the composite board 1 is composed of a surface material 2 such as plywood and a surface material 2 such as plywood. The composite board 1 consists of a fiberboard 3 bonded to the back surface of the fiberboard 3 and a sound-insulating sheet material 4 bonded to the back surface of the fiberboard 3. Many semi-through holes 5, 5,...
is provided.

As the surface material 2, in addition to plywood, materials such as gypsum board, paperboard, particle board, etc., which can be easily applied to decorative cloth on-site, are used.

Examples of the fiberboard 3 include vegetable fiberboards mainly made of wood fibers such as soft fiberboards, and mineral fiberboards made of rock wool, slag wool, glass wool, and the like.

Further, the sound-insulating sheet material 4 may be a soft material made of thermoplastic synthetic resin such as vinyl chloride resin, rubber, etc. mixed with metal powder, metal oxide, other inorganic powder such as barium sulfate, etc., and molded into a sheet shape. Examples include a sound insulation sheet, a metal thin plate such as a lead sheet, and a coating layer formed by applying vinyl chloride sol or a paste-like material mixed with inorganic powder to the back surface of the fiberboard 3.

Further, the diameter of the semi-through hole 5 is not particularly limited, but a hole diameter exceeding 15 mmφ is not preferable because the makeup cloth is likely to be damaged when the makeup cloth is attached to the surface, and is usually around 2 mmφ to 10 mmφ. It is preferable to set it to . In addition, in the above embodiment, the depth was set from the surface of the surface material 2 to the surface of the fiberboard 3, but in order to effectively exhibit sound insulation performance, it is not necessary to penetrate the composite board 1. For example, as shown in FIG. The depth may be as shown in FIG.

That is, in the base material A' shown in FIG. 2, semi-through holes 5' are provided at a depth reaching from the surface of the surface layer 2 to the middle layer of the fiberboard 3, and in the base material A'' shown in FIG. Here, a semi-through hole 5'' is provided at a depth reaching from the surface of the surface layer material 2 to the surface of the sound insulating sheet material 4. The architectural base materials A' and A'' shown in FIGS.
Since they are provided at a depth that reaches the surface, the sound absorption effect of the half-through holes 5' and 5'' can be further enhanced compared to the base material A in Figure 1.In particular, the sound absorption effect of the half-through holes 5' and 5'' can be further enhanced compared to the base material A' in Figure 2. In this case, a fiber board 3 is placed at the bottom of the semi-through hole 5'.
Because the middle layer is located, it is desirable to have both excellent sound absorption and sound insulation performance.

A plurality of base materials A to A'' configured in this manner are butted against each other while being fixed to the wall structure with the sound insulating sheet material 4 on the back side by nailing or using a combination of nails and adhesive. They are joined together and made into a series to form an interior base.Next, if necessary, after performing putty treatment on the joint of base materials A and A'', the surface layer is applied to the surface of the surface material 2 of the base materials A to A''. A decorative cloth is pasted to cover the entire surface of the material 2, including the hole openings, to achieve a cloth-covered finish.

Therefore, the wall structure constructed as described above has a large number of half-through holes 5 to 5'' on the surface of the composite plate 1.
has good sound absorption performance, the fiberboard 3 inside the composite board 1 has good sound absorption property, and the composite board 1 has good sound absorption performance.
Since the sound insulating sheet material 4 on the back side has good sound insulating performance, the sound emitted from the indoor side is absorbed by vibrating the cosmetic cloth on the front side, and then is absorbed by the numerous semi-through holes 5 to 5''. It is further absorbed and attenuated,
By vibrating the fibers as they pass through the fiberboard 3, the sound is absorbed and significantly attenuated, thus providing an excellent sound absorption effect. Furthermore, a sound insulating sheet material 4 on the back side
The sound is reliably insulated and prevented from propagating to the outside, thereby providing an excellent sound insulating effect. As a result, a wall with excellent soundproofing effects can be provided.

Further, the sound insulating sheet material 4 on the back surface of the base materials A to A'' may be provided so as to protrude extra from two adjacent side edges as shown in FIG.
As shown in the figure, the base materials A~
It is possible to reliably insulate sound from leaking from the abutting portions (joints) between the A'' and to effectively utilize the sound insulation effect of the wall.

In addition, the above-mentioned wall structure has a surface material 2 such as plywood provided on the surface of the fiberboard 3 of the base materials A to A'', and the composite board 1,
1 can be formed without creating gaps, and the fiberboard 3 absorbs moisture and moisture.
Since the surface material 2 can suppress expansion and contraction due to dissipation, when the surface material 2 is cross-strung, the hole openings on the surface of the surface material 2 and the joint between the composite plates 1 and 1 can be suppressed. can be completely covered with the makeup cloth, and also can prevent gaps from forming at the joints of the makeup cloth, resulting in a wall surface with an excellent makeup appearance. Furthermore, the cosmetic cloth can be easily and reliably adhered to the surface of the base materials A to A''.

(Effects of the invention) As described above, according to the wall structure of the invention, it is possible to exhibit an excellent soundproofing effect by combining good sound absorption and sound insulation performance, and also to have a cloth finish on the surface with good adhesion and a decorative appearance. Since it can be done well, it is possible to provide walls with excellent soundproofing and decorative finishing properties.
