2. Description of the Related Art Conventionally, a wood-like material (particle board, fiber board) or the like with a decorative surface is pasted with a sheet-like material having a large specific gravity on the back surface of the board under a concrete floor slab or a siding board. A common method is to place it directly on the ground and let it adapt itself to the ground under its own weight. However, if it is left as it is, since it is simply placed on the base, it shifts laterally to form a gap between the floor plates. Therefore, the fitting concave and convex portions formed on the peripheral portion of the substrate are coated with an adhesive and fixed.

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is an explanatory view of a method of constructing a floorboard for laying floor according to the first embodiment of the present invention, and FIG. 2 is an explanatory view of a method of constructing a floorboard for laying floor according to the second embodiment of the present invention. FIG. 3 is a configuration diagram of a floorboard for laying down according to the first and second embodiments of the present invention.

First, the first embodiment shown in FIG. 1 will be described. The floorboard 14 for laying down comprises a substrate 10, a sheet-like material 11 having a large specific gravity, and a suction sheet 12, which is placed on a base surface 13. For the substrate 10, various commonly used wood boards such as plywood, particle board, and fiber board such as MDF are used. Here, the substrate 10 may be surface-coated by sticking a veneer or a decorative paper on the surface. The long side of the substrate 10 is 9
A plate-shaped body having a length of 00 mm, a short side of 120 mm, and a thickness of 9 mm was used, but the outer shape is not limited. On the back surface of the substrate 10, a sheet-shaped material 11 having a larger specific gravity than that of the substrate 10 is attached by applying an adhesive.

The sheet-like material 11 having a large specific gravity is used as the base surface 1.
3 is provided with flexibility and an appropriate weight in order to stably and closely fix the substrate 10 and the base surface 13 even if there are irregularities or the like, and an aggregate such as calcium carbonate or asphalt is weighed. It is a sheet-like material having a thickness of about 2 to 5 mm formed by mixing it with a vinyl chloride resin as an imparting material and adjusting the specific gravity to 1.0 to 1.6. In addition to vinyl chloride resin, a flexible or viscoelastic material such as viscoelastic rubber is preferably used. If the specific gravity is a sheet-like material having a high degree of flexibility as described above, it is possible to maintain appropriate workability and suitability for the base surface 13, and thus the sheet-like material 11 having a large specific gravity.
Can be adopted as. Here, if the specific gravity is less than 1.0, the weight of the floorboard 14 for laying down is too light, so that the effect of adhering to the base surface 13 by its own weight is small, and if the specific gravity is more than 1.6, it becomes too heavy. It is not preferable because it will hinder the handling of the floorboard 14 for laying during construction.

Furthermore, a foaming ratio of 1 to 3 mm is formed on the lower surface of the laminate formed by adhering the sheet-like material 11 having a large specific gravity to the substrate 10, that is, the surface of the sheet-like material 11 having a large specific gravity.
The adsorption sheet 12 made of a foamed soft urethane resin, which is produced by about 20 times, is attached by a urethane modified vinyl adhesive or the like. At this time, without using an adhesive,
It can also be used in a state of being pressed and joined. Here, the sheet used as the adsorption sheet 12 has independent bubbles dispersed therein by a foaming agent in the process of molding,
Although it is made of a soft urethane resin having elasticity and adsorptivity, other adsorptive polymer resin or the like can be used as the adsorptive sheet 12. And the base surface 13
In order to maintain the adsorptivity with, it is preferable to use the one containing about 50 to 80 vol% of bubbles having a diameter of 0.5 to 2 mm. The foamed soft urethane sheet is flexibly fitted and closely fixed to the uneven portion of the base by the suction force of the foamed portion. Therefore, even if it is not fixed with an adhesive or a nail, since the frictional force against the lateral displacement acts largely due to the unevenness of the joint surface or the suction force, the floorboard 1
4 can be made hard to shift from the base surface 13.

As shown in FIG. 1, the floorboard 14 for laying the substrate 10, the sheet 11 having a large specific gravity, and the adsorption sheet 12 produced as described above is placed on the base surface 13 made of a concrete floor slab. It was placed and subjected to flooring construction. As shown in FIG. 3, due to the weight of the sheet-like material 11 having a large specific gravity, the flexibility, and the adsorptivity of the suction sheet 12, the floorboard 14 for laying is simply placed on the ground surface 13, and the unevenness of the ground surface 13 Since it easily fits in and the meshing occurs at the uneven joint surface between the base surface 13 and the suction sheet 12, it does not easily slip once placed, and the construction work of the floorboard 14 for laying can be performed very easily. It was Further, at this time, unlike the conventional case, it is not necessary to apply adhesive agent to the fitting concave-convex portion, so that the construction time is about 2 / compared with the conventional case.
Shortened to 3. Further, after the construction, the floorboard 14 for laying down is not completely fixed as in the conventional case, and the sheet-like material 11 having a large specific gravity and the adsorption sheet 12 made of a foamed soft urethane resin are used for the floorboard 14 for laying down. In order to disperse the impact load applied to the surface, the excessive load applied to the substrate 10 was reduced, and the durability of the floorboard 14 for laying could be improved. Even when the flooring is refurbished, it is easy to remove and the floorboard 14
No deviation was observed during the period of use and the adhesion was extremely good.

In the second embodiment shown in FIG. 2, the adsorbing sheet 12 made of the independent foaming soft urethane resin is not attached to the substrate 10 side on which the sheet-like material 11 having a large specific gravity is attached, but the base surface 13 is provided. After laying it in advance, the substrate 10 having a sheet-like material 11 having a large specific gravity adhered to the back surface is placed on the upper surface of the adsorption sheet 12 to form a floorboard 14 for laying as shown in FIG. It was constructed. Here, the sheet-like material 11 made of recycled rubber having a specific gravity of 1.2 and having a large specific gravity and the base surface 13 are the adsorption sheets 12.
It is fixed by the adsorption force of. Compared with the first embodiment, the amount of adhesive used is less, and the floorboard 14 for laying down is used.
The construction and dismantling can be performed more easily, and the adsorption sheet 12 made of the foamed soft urethane resin can be reused.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and changes in conditions and the like without departing from the gist are all within the scope of the present invention. For example, in this embodiment, the case where the independent foaming soft urethane sheet is used as the adsorption sheet 12 has been described, but the present invention is also applied to porous rubber and other polymer materials as long as it is an adsorbing sheet. be able to.

[0014]

According to the floorboard for laying down according to claim 1, the floorboard for laying down is a substrate, a sheet-like material having a large specific gravity,
Further, since it is composed of a laminated body of adsorption sheets such as foamed soft urethane sheet, it is flexibly adsorbed and fixed to the uneven portion of the lower ground such as concrete floor slab by the adsorption force of the lowermost adsorption sheet. Therefore, it is not necessary to apply an adhesive to the fitting concavities and convexities as in the conventional case, and it is possible to perform the construction very easily even by an amateur even by simply placing it on the base surface. Further, even after the construction, since the frictional force largely works due to the unevenness on the surface of the suction sheet and the suction force, the friction does not easily shift. Furthermore, since the floor sheet for underlay is not completely fixed, the impact load applied to the floor sheet for underlay can be dispersed, and the durability of the floor sheet for underlay can be improved. Also,
At the time of refilling, the floorboard for laying can be easily peeled off from the base surface by simply applying a force in a direction perpendicular to the base surface.

According to a second aspect of the present invention, there is provided a method for constructing a floorboard for underlaying, which is the method for constructing a floorboard for underlaying arranged on a lower ground such as a concrete floor slab. Laying the floor sheet for laying, on which a sheet-like material having a larger specific gravity than the substrate is attached, on the suction sheet, it is not necessary to fix the floor sheet to the base surface with nails or adhesives, so construction It takes only a short time and can be easily disassembled.
