Description

[Detailed description of the invention] [Industrial application field] The present invention is a laminated sheet for subflooring, which is a type of construction material and is laid between a flooring material such as a wooden floor and a floor base material such as a slab. Regarding.

[Conventional technology]

Conventionally, for example, when a wooden floor is used as the flooring material for a concrete house, soundproofing and vibrationproofing measures have been taken by increasing the thickness of the slab that is the flooring base material.

In recent years, research and development has progressed on soundproofing and vibration-proofing subflooring materials that are placed between flooring materials and floor base materials, and today there are many subflooring materials such as soft elastic urethane foam and hard elastic synthetic rubber. There is a sheet for

[Problem that the invention attempts to solve]

By the way, as mentioned above, since the urethane foam sheet for flooring material is a soft elastic body, it collapses under the load from the upper surface side and loses its soundproofing and vibration-proofing properties. Since the sheet is a hard elastic material, it will not collapse under the load from the top side like urethane foam, but it is relatively inflexible and cannot obtain appropriate elasticity, making it difficult to achieve soundproofing and vibrationproofing properties. It wasn't very good.

The present invention was made against the background of such conventional technology, and an object of the present invention is to provide a laminated sheet for underfloor material that can improve soundproofing properties and vibrationproofing properties.

[Means for solving problems]

That is, the present invention provides a laminated sheet for underfloor material, characterized in that a predetermined number of woven and/or knitted fabrics made of synthetic fibers with a fiber diameter of 0.3 to 3 mm are laminated.

[Effect]

The laminated sheet for flooring material of this invention has a fiber diameter of
Since it is formed by laminating a predetermined number of woven and/or knitted fabrics made of synthetic fibers of 0.3 to 3 mm, a suitable gap is created between the thick denier synthetic fibers of each fabric to provide good soundproofing properties. Since it is woven or knitted from extremely thick denier synthetic fibers, it has good cushioning properties and good vibration-proofing properties, so it is possible to improve the soundproofing and vibration-proofing properties of this laminated sheet. can.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

In describing this embodiment, a laminated sheet for a subfloor material used as a subfloor material for a concrete house will be taken as an example.

The laminated sheet for flooring material according to the embodiment of the present invention shown in FIG. 1 is obtained by laminating a predetermined number of woven fabrics 10 and/or knitted fabrics 20 made of synthetic fibers having a fiber diameter of 0.3 to 3 mm.

In addition, in the laminated sheet for flooring material of this example,
A woven fabric 10 is constructed by weaving warp yarns (rigid fibers) 11 and weft yarns (synthetic fibers) 12 made of polyester stiff yarns each having a fiber diameter of 0.7 mm.
A knitted fabric 20 made by knitting a knitting yarn (synthetic fiber) 21 made of 0.8 mm polyester filament yarn is laminated.

In addition to polyester, examples of the material for the woven fabric 10 include polyethylene, polypropylene, nylon, etc.
In addition, examples of the material include materials similar to those used for the woven fabric 10.

Furthermore, the fiber diameters of the woven fabric 10 and knitted fabric 20 are not limited to the above, but are 0.3 to 3 mm,
Preferably, a thickness of 0.5 to 2 mm is used; if the thickness is less than 0.3 mm, the elasticity of the woven fabric 10 and the knitted fabric 20 will be weakened, and the entire sheet will become flattened, reducing the soundproofing and vibration-proofing effects. On the other hand, if the thickness exceeds 3mm As the woven fabric 10 and knitted fabric 20 become sparse, the improvement in vibration damping properties becomes smaller.
In addition, processing into woven or knitted fabrics is generally difficult.

Furthermore, in this embodiment, one woven fabric 10 and one knitted fabric 20 are laminated, but any number of woven fabrics 10 and/or knitted fabrics 20 may be laminated thereon, or other woven fabrics may be used. Only 10 cloths,
Alternatively, it may be formed by laminating a plurality of knitted fabrics 20 alone.

In addition, in FIG. 2, the reference numeral 30 indicates a wooden floor, which is the flooring material of a concrete house, and the reference numeral 40
is the floor base slab.

This laminated sheet for flooring material is used by laying it between the wooden floor 30 and the slab 40 with the woven fabric 10 side facing the wooden floor 30 side as shown in FIG.
Sound from the wooden floor 30 or slab 40 side is blocked by the appropriate gaps formed between the thick warp yarns 11 and weft yarns 12 of each cloth 10, 20 and between the knitting yarns 21. slab 4
Vibration from the 0 side is suppressed by the elastic force obtained by weaving or knitting these thick synthetic fiber warp yarns 11, weft yarns 12, and knitting yarns 21, which improves the cushioning properties of the sheet and provides good vibration damping properties. ,
Therefore, the soundproofing properties and vibrationproofing properties of this laminated sheet for flooring material can be improved.

As explained above, the vibration isolating sheet of the example is made by laminating a predetermined number of woven fabrics 10 and/or knitted fabrics 20 made of synthetic fibers with fiber diameters in the range of 0.3 to 3 mm. The soundproofing properties and vibrationproofing properties of the laminated sheet for materials can be improved.

In addition, in the example, the warp yarn 1, which is a synthetic fiber,
1. Since oliester bristle yarn is used as the material for the weft yarn 12 and the knitting yarn 21, the flooring material has strong weft elasticity and less material set.

Although the embodiments of the present invention have been described above, the specific configuration and operation are not limited to these embodiments, and any design changes that do not change the gist of the present invention are also included in the present invention. .

For example, in the embodiment, a laminated sheet for the subfloor material of a concrete house was used as an example, but the laminated sheet for the subfloor material of the present invention can also be used as a subfloor material for other buildings.

[Effect of idea]

In this invention, a predetermined number of woven and/or knitted fabrics made of synthetic fibers with fiber diameters in the range of 0.3 to 3 mm are laminated, thereby improving the soundproofing and vibration-proofing properties of this laminated sheet. This effect can be obtained.
