By the way, from the viewpoint of environmental protection such as waste reduction and resource reuse and effective use of resources, the building can be easily dismantled, and the members generated by the dismantling of the building are reused as new building members. Is desirable. However, in the above-mentioned conventional floor structure, the work of removing the floor base material such as the floor finishing base material from the base such as the deck plate while maintaining the reusable state is complicated, and such workability constitutes the floor structure. It was one of the factors that hindered the reuse of the members.

The present invention has been made in view of these circumstances, and an object of the present invention is to provide a floor panel and a floor structure that can be easily disassembled and reused.

The floor panel for solving the above problems is a floor panel arranged on a base, and includes a floor base material and an adhesive layer having an adhesive surface to be adhered to the base.
According to this configuration, the floor panel can be easily removed from the base while maintaining a reusable state by peeling off the adhesive surface of the adhesive layer from the base.

It is preferable that the floor panel further includes a leg member attached to the floor base material, and the adhesive layer is attached to the leg member.
According to this configuration, the leg member makes it possible to exert, for example, a cushioning function or a non-landing adjusting function.

In the floor panel, the shape of the floor base material is a quadrilateral in a plan view, and the adhesive layer arranged at a position adjacent to at least one side of the four sides of the floor base material is directed toward the one side. It is preferable that the adhesive surface has a small shape.

Here, when the work of removing the floor panel from the base by lifting any one side of the floor panel is started, the adhesive layers arranged at positions adjacent to the one side of the floor panel are arranged in order from the portion closest to the one side. Is peeled off from. If the adhesive force of the portion where the peeling of the adhesive layer is started is strong in this way, the load on the operator increases when the work of removing the floor panel from the base is started, or an excessive force is applied to the floor panel. There is a risk of According to the above configuration, the adhesive strength of the adhesive layer becomes weaker toward the one side. Therefore, the resistance force at the start of peeling of the adhesive surface from the base can be reduced. Therefore, when the floor panel is removed from the base, the load on the operator can be reduced and the excessive force applied to the floor panel can be suppressed. That is, the floor structure can be preferably disassembled.

In the floor panel, it is preferable that the adhesive layer has a longitudinal direction in which a wide portion and a narrow portion are connected in a plan view, and the narrow portion is arranged so as to face the one side.

For example, with the structure of the adhesive layer as described above, the floor structure provided with the floor panel can be suitably disassembled.
In the floor panel, the adhesive layer is preferably composed of a foam having self-adhesiveness.

According to this configuration, when the floor panel is arranged on the base, the adhesive layer is easily compressed and deformed. Therefore, for example, even when the surface roughness of the upper surface of the base is relatively high, the adhesion of the adhesive layer to the upper surface can be ensured. This makes it possible to stably fix the floor panel on the base.

The floor structure for solving the above problems is a floor structure including the floor panel and the base, and the base is a metal deck plate having a convex portion on the upper surface, and the convex on the deck plate. The floor panel has a structure in which the floor panel is arranged on the deck plate by adhering the adhesive surface to the portion.

Hereinafter, embodiments of the floor structure provided with the floor panel will be described with reference to the drawings.
As shown in FIG. 1A, the floor structure 11 of the present embodiment includes a metal deck plate 21 as a base and a floor panel 31 arranged on the deck plate 21.

The deck plate 21 has irregularities on its upper and lower surfaces. The convex portion 21a on the upper surface of the deck plate 21 has a longitudinal direction L1. As the deck plate 21, for example, a deck plate 21 specified in JIS G3352 is used. The deck plate 21 may be integrally molded or may be formed by connecting a plurality of constituent members.

As shown in FIGS. 1A and 1B, the floor panel 31 is arranged on the convex portion 21a on the upper surface of the deck plate 21. The floor panel 31 includes a floor base material 32, a leg member 33 attached to the floor base material 32, and an adhesive layer 34 attached to the leg member 33.

The shape of the floor base material 32 is a quadrilateral in a plan view, and more specifically, a rectangular shape having a longitudinal direction L2. The floor base material 32 is made of, for example, a wood-based material such as particle board. The floor base material 32 is arranged as a support for a floor finishing material (not shown). Examples of the floor finishing material include flooring, cork board, tile, tatami mat, carpet, resin sheet material and rubber sheet material.

As shown in FIG. 2, a plurality of leg members 33 are attached to the lower surface of the floor base material 32. The leg member 33 has a longitudinal direction L3 along the short side 32b (short direction S2) of the floor base material 32. The leg member 33 preferably has a cushioning function or a non-landing adjusting function. Examples of the material of the leg member 33 include a material in which chip-shaped urethane foam is bonded with a binder, a fiber-based material, and the like. The leg member 33 is fixed to the floor base material 32 with, for example, an adhesive. The leg member 33 may have a single-layer structure or a multi-layer structure in which a plurality of layers are joined.

The adhesive layer 34 has an adhesive surface 34a that is adhered to the convex portion 21a of the deck plate 21. The adhesive layer 34 may be a foam or a non-foam. The adhesive layer 34 is preferably composed of a self-adhesive foam. The adhesive layer 34 of the present embodiment is made of an acrylic foam (acrylic resin foam) having self-adhesiveness. The adhesive surface 34a of the adhesive layer 34 serves as an interface that is peeled off from the deck plate 21 when the floor panel 31 is removed from the deck plate 21. More specifically, the adhesive force of the adhesive surface 34a to the deck plate 21 is configured to be weaker than the strength between the layers of the floor panel 31, such as the adhesive force of the adhesive layer 34 to the leg member 33. The adhesive layer 34 may be attached to the leg member 33 by self-adhesiveness, or may be attached to the leg member 33 by an adhesive to increase the bonding force between the adhesive layer 34 and the leg member 33. The adhesive layer 34 preferably has an outer shape smaller than that of the leg member 33 in a plan view.

The adhesive layer 34 of the present embodiment is composed of a plurality of members attached to each of the plurality of leg members 33. The plurality of adhesive layers 34 form a row adjacent to each other along one long side 32a of the floor base material 32 and a row adjacent to each other along the other long side 32a. The plurality of adhesive layers 34 arranged adjacent to one long side 32a have a shape in which the adhesive surface 34a becomes smaller toward the one long side 32a. Further, the plurality of adhesive layers 34 arranged adjacent to each other on the other long side 32a have a shape in which the adhesive surface 34a becomes smaller toward the other long side 32a.

More specifically, the adhesive layer 34 of the present embodiment has a longitudinal direction L4 in which the wide portion 34b and the narrow portion 34c are connected in a plan view. The width dimension of the adhesive layer 34 refers to the dimension of the adhesive layer 34 along the long side 32a adjacent to the adhesive layer 34. The adhesive layer 34 has a narrow portion 34c facing the long side 32a adjacent to the adhesive layer 34. The narrow portion 34c of the adhesive layer 34 has a shape in which the width becomes narrower as it approaches the long side 32a. That is, the narrow portion 34c of the adhesive layer 34 has an edge inclined with respect to the long side 32a adjacent to the adhesive layer 34. The angle of the edge inclined in the narrow portion 34c is preferably in the range of, for example, 10 ° or more and 80 ° or less with respect to the long side 32a adjacent to the adhesive layer 34.

Next, the main operation of the floor structure 11 provided with the floor panel 31 will be described.
As shown in FIGS. 1A and 1B, the floor structure 11 is assembled by arranging a plurality of floor panels 31 on the deck plate 21. At this time, the floor panel 31 is arranged so that the leg member 33 of the floor panel 31 is located on the convex portion 21a of the deck plate 21. Further, the floor panel 31 is arranged so that the longitudinal direction L2 of the floor base material 32 is orthogonal to the longitudinal direction L1 of the convex portion 21a of the deck plate 21. When assembling the floor structure 11, the adhesive layer 34 of the floor panel 31 is adhered to the convex portion 21a of the deck plate 21, so that the plurality of floor panels 31 are sequentially assembled while suppressing the misalignment of the floor panel 31. Can be placed. In the floor panel 31 before being arranged on the deck plate 21, the adhesive surface 34a may be protected by providing the release sheet material on the adhesive surface 34a. The floor structure 11 can be suitably used as a floor structure of a building having a limited period of use.

Here, when the floor structure 11 is disassembled, as shown in FIG. 2, the plurality of floor panels 31 are sequentially removed from the deck plate 21 by lifting one of the long sides 32a of the floor panel 31. At this time, the floor panel 31 is adhered to the deck plate 21 by the adhesive surface 34a of the adhesive layer 34. Therefore, by peeling the adhesive surface 34a from the deck plate 21, the floor panel 31 can be easily removed from the deck plate 21 while maintaining a reusable state. For example, when removing the floor panel 31 from the deck plate 21, it is possible to avoid complicated work such as loosening a plurality of screws, and to avoid damage to the floor panel 31 due to forgetting to remove the screws. ..

The floor panel 31 generated by dismantling the floor structure 11 as described above can be reused as a newly assembled floor panel for the floor structure. The floor panel 31 may be reused for a floor structure different from the floor structure 11. In this case, the leg member 33 or the adhesive layer 34 of the floor panel 31 may be removed, or another member may be attached to the floor base material 32. The deck plate 21 can be reused in the same manner as the floor panel 31.

The effects exerted by the above-described embodiments will be described below.
(1) The floor panel includes a floor base material 32 and an adhesive layer 34 having an adhesive surface 34a that is adhered to the deck plate 21. According to this configuration, the floor panel 31 can be easily removed from the deck plate 21 while maintaining a reusable state by peeling the adhesive surface 34a of the adhesive layer 34 from the deck plate 21. Therefore, the floor structure 11 provided with the floor panel 31 can be easily disassembled and the floor panel 31 can be reused.

(2) The floor panel 31 further includes a leg member 33 attached to the floor base material 32, and the adhesive layer 34 is attached to the leg member 33. In this case, the leg member 33 makes it possible to exert, for example, a cushioning function or a non-landing adjusting function. Therefore, the usage state of the floor structure 11 provided with the floor panel 31 can be improved.

(3) When the work of removing the floor panel 31 from the deck plate 21 by lifting one long side 32a of the floor panel 31 is started, the adhesive layer 34 arranged at a position adjacent to the long side 32a is the adhesive layer 34. It is peeled from the deck plate 21 in order from the portion closest to the long side 32a. If the adhesive force of the portion where the peeling of the adhesive layer 34 is started is strong in this way, the load on the operator increases when the work of removing the floor panel 31 from the deck plate 21 is started, or the floor panel 31 is excessive. There is a risk that excessive force will be applied.

In the floor panel 31 of the present embodiment, the adhesive layer 34 arranged at a position adjacent to at least one side (at least one long side 32a) of the four sides of the floor base material 32 is directed toward one side (long side 32a). It has a shape in which the adhesive surface 34a becomes smaller. In this case, the adhesive strength of the adhesive layer 34 becomes weaker toward the one side (long side 32a). Therefore, it is possible to reduce the resistance force at the time of starting the peeling of the adhesive surface 34a from the deck plate 21. Therefore, when the floor panel 31 is removed from the deck plate 21, the load on the operator can be reduced and the excessive force applied to the floor panel 31 can be suppressed. That is, the floor structure 11 can be preferably disassembled.

Has a shape in which the adhesive surface 34a becomes smaller toward the adjacent long sides 32a. In this case, in the work of removing the floor panel 31 from the deck plate 21, the floor structure 11 can be suitably disassembled as described above regardless of which side of the long side 32a the floor panel 31 is removed from.

(4) The adhesive layer 34 of the floor panel 31 has a longitudinal direction L4 in which the wide portion 34b and the narrow portion 34c are connected in a plan view. Further, the adhesive layer 34 is arranged such that the narrow portion 34c faces at least one side (at least one long side 32a) of the four sides of the floor base material 32. For example, with such a structure of the adhesive layer 34, the action and effect described in (2) above can be obtained.

(5) The adhesive layer 34 of the floor panel 31 is preferably composed of a foam having self-adhesiveness. In this case, when the floor panel 31 is arranged on the deck plate 21, the adhesive layer 34 is easily compressed and deformed. Therefore, for example, even when the surface roughness of the convex portion 21a of the deck plate 21 is relatively high, the adhesion of the adhesive layer 34 to the convex portion 21a can be ensured. As a result, the floor panel 31 can be stably fixed on the deck plate 21.

(6) The floor structure 11 has a structure in which the floor panel 31 is arranged on the deck plate 21 so that the longitudinal direction L1 of the convex portion 21a of the deck plate 21 and the longitudinal direction L2 of the floor base material 32 intersect. ing. In this case, the floor panel 31 is relatively stable and easily supported on the deck plate 21. For example, as in the present embodiment, one floor panel 31 can be stably supported by three or more convex portions 21a.

Further, although not shown, it may be an adhesive layer having a circular shape in whole or a part, or an adhesive layer in which a narrow portion 34c is formed in a comb-teeth shape. Even in this case, the effects described in (3) above can be obtained.

The shape of the adhesive layer 34 has a shape in which the adhesive surface 34a becomes smaller toward one side (long side 32a) of the floor base material 32, but is not limited to such a shape. That is, the shape of the adhesive layer 34 may be a shape in which the width dimension along one side of the floor base material 32 is constant, or a shape in which the adhesive surface 34a becomes larger toward the one side.
