Description

[Detailed description of the invention] (Technical field) The present invention relates to a moisture-proof floor panel that constitutes the floor of a building. This invention relates to a moisture-proof floor panel in which a sheet is stretched on the bottom surface of a wooden panel.

(Prior Art) In order to improve the durability of a building, it is necessary to improve the durability of each part of the building itself, such as floors, walls, and roofs.

In particular, the floor is installed closest to the ground, so
Easily affected by moisture from the ground. For that reason,
Conventionally, concrete is poured into the ground beneath the floor.
Methods of using so-called dirt-floor concrete floors and incorporating moisture-proofing materials inside the flooring materials have been adopted. Furthermore, there have been proposed resin sheets with high moisture resistance, and resin sheets in which a hollow partition material is sandwiched between the resin sheets, and a so-called hollow outer surface material is stretched over the lower surface of the floor material.

(Problems with conventional technology) Each of the moisture-proofing means described above requires a great deal of labor to construct on-site, and the outer surface material, which is constructed in a hollow shape stretched over the bottom surface of the flooring material, is simply a hollow resin sheet. Therefore, it is weak in strength, and the moisture-proofing effect may be significantly reduced, such as damage to the resin sheet itself during construction on site.

(Means for solving the problems) This invention was devised in view of the above problems.
To provide a moisture-proof floor panel in which a moisture-proof sheet made of a non-woven fabric as a base material and a resin film pasted on the bottom surface of a wooden panel made by assembling frame materials into a substantially rectangular shape and laying floor plywood on the top surface of the wooden panel. It is something to do.

(Function) The moisture-proof sheet stretched on the bottom surface of the wooden panel is made of non-woven fabric as a base material and a resin film is attached to it, so the non-woven fabric itself has tensile resistance even when subjected to external forces in the plane direction and in the direction perpendicular to the plane. The so-called moisture-proof sheet itself has extremely high tensile resistance, the sheet itself does not break, and the moisture-proof floor panel as a whole exhibits high moisture-proof properties.

(Example) Hereinafter, the moisture-proof floor panel of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic cross-sectional view of the moisture-proof sheet 1. FIG. This moisture-proof sheet 1 has a base material of a nonwoven fabric 11 formed by bundling fibrous materials such as polypropylene (P, P), polyethylene (P, E), polyester, etc., and a resin film 12 of polypropylene, polyethylene, polyester, etc. It is pasted.
The nonwoven fabric 11 and the resin film 12 are attached by applying an adhesive such as water-based vinyl urethane in a uniform thin film and rolling the two together with a roll. Alternatively, it can be applied directly with a hot pressure roll. The so-called moisture-proof sheet 1 is a nonwoven fabric 1
1 is used as a base material, and this base material bears external forces in the plane direction and the direction perpendicular to the plane, so it has sufficient strength against external forces such as tearing force.

On the other hand, the resin film 12 itself does not bear any external force directly, and the resin film 12 itself has moisture resistance.

FIG. 2 is a partially omitted perspective view of a moisture-proof floor panel P in which the moisture-proof sheet 1 is stretched over the lower surface of the wooden panel 2. As shown in FIG.

The wooden panel 2 has frame members 21, 21... assembled in a substantially rectangular shape, and reinforcing crosspieces are assembled in a lattice shape within this rectangular shape as required.

A floor plywood 22 is laid on the upper surface of the frame members 21, 21..., and glass wool G or the like as a heat insulating material is sealed between the lattice-shaped crosspieces as necessary.

The moisture-proof sheet 1 described above is stretched over the entire lower surface of the wooden panel 2 having the above configuration. As for the work of stretching the moisture-proof sheet 1, since the moisture-proof sheet 1 itself has a high tensile strength, it is made into a rolled endless type in advance, and the dimensions are adjusted while sequentially placing it on the wooden panels 2 conveyed from the conveyor. It is possible to cut and stretch it. In this regard, conventional outer surface materials with a hollow structure have low tensile strength and cannot be made into an endless type, so they are cut into predetermined sizes, stacked in a stockyard, and placed one by one on wooden panels, which reduces productivity. It makes a big difference. Moreover, the moisture-proof sheet of the present invention is wound into an endless roll and only needs to be cut before being stretched, so the area of the stockyard, etc. is also reduced, and the overall manufacturing cost is significantly reduced.

FIG. 3 is a partially omitted sectional view showing a state in which a moisture-proof floor panel P on which the above-mentioned moisture-proof sheet 1 is stretched is laid between foundations B and B.

That is, the ends of the moisture-proof floor panel P are placed on the foundations B, B, and the outer wall panel 3 and the inner wall panel 4 are placed on top of this.
A building is constructed by erecting. As mentioned above, when building the moisture-proof floor panel P, the nonwoven fabric 11 bears all the external forces caused by collisions with other members and the corners of the foundations B and B, and the resin film 12 does not tear. It will not be subject to any damage such as

Therefore, the glass wool G in the moisture-proof floor panel P does not absorb moisture from under the floor. Furthermore, frame materials 21,2
1...and the floor plywood 22 itself does not absorb moisture,
The durability of the entire floor is significantly improved.

(Effects) As explained above, the moisture-proof floor panel of the present invention has the following remarkable effects.

The strength of the moisture-proof sheet is improved, there is no damage during on-site construction, and the specified moisture-proof performance is always ensured. This greatly improves the durability of the building.

When installing the moisture-proof sheet, it can be supplied in an endless state, which greatly improves productivity.

Similarly, since the moisture-proof sheet can be wound into a roll, the stock yard and the like are reduced, and the overall manufacturing cost is also reduced.

Since the moisture-proof sheet is made of non-woven fabric as a base material and a resin sheet is attached to it, the material cost is also reduced compared to conventional sheets.
