Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a flooring material having a soundproofing effect.

[Background technology]

Floors of buildings made of steel frames, reinforcing bars, etc. are often made by laying floor finishing materials such as wooden tiles, synthetic resin tiles, rubber tiles, etc. on a floor base made of concrete or the like.

For example, using wooden tiles as a floor finishing material has the advantage of making rooms look calmer and adding a sense of luxury to buildings, but wooden tiles have poor sound absorption properties. Therefore, there are disadvantages such as the sound of footsteps echoing. On the other hand, synthetic resin tiles and rubber tiles have higher sound absorption properties than wooden tiles, so using them as floor finishing materials has the advantage of not making the sound of footsteps as loud, but it also gives the building a luxurious feel. The disadvantage is that it is difficult to provide

Therefore, a soundproof flooring material as shown in Figure 1 was developed. This soundproof flooring material 1 has wooden pieces 1b laid out in a small checkerboard pattern or the like without gaps, and is adhered to the surface of a sheet 18 made of a sound-absorbing material. Woody Pea 7-1
A material having a thickness of about 3.0 to 8.0 m is used for the material B, and a material having a thickness of about 2.0 m is used for the material Ilk. When such soundproof flooring material 1 is laid and fixed on the flooring as shown in the figure, the wooden piece 1b
Since the upper surface constitutes the floor surface, the room etc. can become calm and it can also give a sense of luxury to the building. Moreover, since a 1 m thick sheet made of sound absorbing material is provided on the back side of the wooden beef 1b, a soundproofing effect can be obtained.

However, such soundproof flooring materials have the following problems: ■ The soundproofing effect is low, ■ The wood piece easily peels off from the sheet, and ■
Wooden pieces are subject to large dimensional changes due to humidity and other factors, so the expansion and contraction of wooden pieces has caused problems such as spoiling the aesthetic appearance of the floor surface.

[Purpose of the invention]

This invention was made in view of the above circumstances, and consists of a sheet and a piece made of ceramics, ceramic 1, plastic, marble, metal, etc., and has a great soundproofing effect, and the piece is made from a sheet. The purpose of the present invention is to provide a soundproof flooring material that does not peel off easily, does not shrink, does not expand or contract, does not cause uplifting phenomena, and does not impair the aesthetic appearance of the floor surface.

[Disclosure of the invention]

In order to achieve the above object, the present invention includes a sheet made of a sound absorbing material, in which a predetermined number of pieces are embedded and joined together at intervals from each other and with the front side portions protruding. The gist of this is soundproof flooring.

Hereinafter, the present invention will be described in detail based on the drawings.

2 and 3 show the soundproof flooring material according to the present invention. As shown in the figure, this soundproof flooring material 2 consists of a predetermined number of pieces 2b made of a sound-absorbing material, spaced apart from each other, and with the front side protruding.
... is embedded and joined together. As the sound absorbing material, for example, soft rubber such as silicone rubber, soft plastic material, etc. are used. When using soft rubber, soft plastic, or clay, it is preferable to use one having a hardness (Shore hardness) of 10 to 70'. The thickness of the sheet is 3.0 considering the sound absorption effect, the feeling of walking, and the ability to absorb some unevenness in the flooring.
The thickness of the beef is preferably 1 to 2 pm. Further, it is preferable that the pieces are spaced apart by 0.5111 or more.

The size of the sheet or piece and the number of pieces to be joined to the sheet are determined as appropriate depending on the installation location, etc.

For example, the sheet is a square of 1801 m x 180 (!), and the size of the pieces is IQ 112 x IQ c
As a square shape, leave 1 cm between the pieces.

In the soundproof flooring material according to the present invention, spaces are provided between the pieces, and the bases of the pieces are embedded in the seams, so that one piece 2, as shown in FIG.
The sound A, such as the amount of walking that has passed through the piece 2b, is blocked by the sound-absorbing material surrounding the piece 2b, making it less likely to be affected by the neighboring piece 2bK@. Therefore, compared to a soundproof flooring material in which wooden pieces are spread tightly over the seat surface, sound is less likely to be transmitted toward the guests, and the sound absorption effect is higher. Moreover, since there are gaps between the pieces that serve as joints from the beginning, even if the dimensions of the pieces change, this gap absorbs the dimensional changes, so the aesthetic appearance of the floor is not impaired. Since the piece is embedded in the sheet, the contact area between the piece and the sheet is larger than when the piece is simply adhered to the surface of the sheet.

Therefore, it is difficult to peel off from the sheet. By appropriately determining the spacing and protrusion height of the pieces, it is possible to eliminate problems such as people tripping on the end faces of the pieces, even if the heights of the pieces are slightly different. The soundproof flooring material according to the present invention does not require nailing and can be fixed to the subfloor with adhesive, so it is easy to install. However, it may be fixed to the flooring base rather than nailing K.

The soundproof flooring material according to the present invention can be produced by, for example, pouring the liquid sound-absorbing material into a mold, then filling it with a predetermined number of beef pieces with spaces apart and K so that the 011 part protrudes, and then hardening the sound-absorbing material. It is also possible to arrange a large number of pieces in a predetermined manner by fitting them into a mold on the front side of the piece, and then pour the sound absorbing material into the back side of the piece and allow it to harden.The sound absorbing material can be placed in the mold. Instead of pouring it, you can pour it directly onto the subfloor and place the pieces on top of it.

In the embodiment described above, the square pieces are arranged parallel to each other, but it is not necessary to do so. As shown in Fig. 4, rectangular pieces 6 may be arranged on the sheet 5, or small chip-shaped wooden pieces may be partially exposed and embedded in the sheet and joined. They may even be integrated.

The soundproof flooring material according to the present invention can also be used as wall material, ceiling material, etc.

〔Effect of the invention〕

The soundproof flooring material according to the present invention has a soundproofing effect because a predetermined number of pieces are embedded and integrated into a sheet made of sound absorbing material at intervals and with the front side protruding. It's thick, so the pieces won't peel off from the sheet or spoil the aesthetics of the floor.
