Further, in RC construction, the floor foundation 2 is composed of a wooden frame formed on a concrete slab and a plywood laid on the wooden frame.

  In the present embodiment, the floor sheet S is exemplified to include the base 31 and the protrusions 4. The base 31 has a planar rectangular sheet shape, and the length of one side thereof is, for example, about 900 to 1800 mm, preferably about 900 mm. In this example, the length is a roll shape and is formed in a length of 10,000 mm and a width of 900 mm. The thickness T2 is, for example, about 1 to 3 mm, preferably about 1 to 2 mm, and in this example 2 mm.

  As shown in FIG. 3 (B), the protrusion 4 is integrally projected on the surface of the base 31 and has a cylindrical shape in this embodiment. In addition to the above, the protrusion 4 may have various shapes such as a rectangular parallelepiped shape as shown in FIG. 5A and a short triangular prism shape as shown in FIG. 5B. it can.

  As shown in FIGS. 3B, 5 </ b> A, and 5 </ b> B, the protrusion 4 according to this embodiment is illustrated with a hollow portion 6 provided therein. When the protrusion 4 is provided with the hollow portion 6, the protrusion 4 functions as an air cushion, so that the cushioning function of the floor can be enhanced and the floor vibration generated on the upper floor is absorbed. It is preferable in that it can be further increased. .

  Further, in this embodiment, as shown in FIGS. 2 and 3B, the protrusions 4 are arranged in a certain shape and arranged vertically and horizontally at equal intervals.

If the distance exceeds 100 mm, the fixing strength of the floor covering 3 is insufficient, and if it is less than 30 mm, the workability of the fixing operation of the floor covering 3 is deteriorated.

  As shown in FIG. 3 (B), the protrusions 4 located on the outermost side of the floor sheet S are formed so that the distance from the outer edge is half of the distance P between the protrusions 4. The interval between the protrusions 4 and 4 located on the outer edge between the floor sheets S and S that are continuously laid is equal to the interval P. As a result, all the protrusions 4 of the floor sheet S laid continuously are arranged at the same interval P.

  The protrusion 4 has a diameter D of, for example, about 10 to 50 mm, preferably about 10 to 30 mm, and in this example, 20 mm. When the diameter D exceeds 30 mm, the fixing strength of the floor finishing material 3 is insufficient. When the diameter D is less than 10 mm, the fixing strength of the floor finishing material 3 is insufficient and the workability of the fixing operation of the floor finishing material 3 is deteriorated. The height H is, for example, about 3 to 6 mm, preferably about 5 to 6 mm, and in this example, 5 mm. If the height H exceeds 6 mm, the strength of the floor finish 3 fitted thereto is lowered, and if it is less than 3 mm, the fixing strength of the floor finish 3 is insufficient.

  The floor sheet S uses a plastic material such as polyethylene, polypropylene, and polystyrene, and the base 31 and the protrusions 4 are integrally formed. In addition, when an elastic material such as an olefin, styrene or other thermoplastic elastomer, an elastic resin containing ethylene vinyl acetate copolymer resin (EVA), or a synthetic rubber containing chloroprene rubber, styrene butadiene rubber or nitrile rubber is used.

  Further, in this embodiment, as shown in FIG. 2, the floor sheet S covers the floor base 2 formed by continuously laying a plurality of floor panels 8 as described above at a position covering the connecting portion 7 of the floor panel 8. What was laid is illustrated. Thereby, even if a floor panel generates a relative movement due to an earthquake, traffic vibration, wind load, etc., and a step, a gap, a deviation, etc. occur in the connecting portion 7 of the floor panel, these movements are caused by the floor sheet. Since it is pressed by S, or steps, deviations, etc. are absorbed, cracks, warpage, etc. do not occur in the floor finish.

  As shown in FIGS. 1 and 2, the floor covering material 3 is formed in a planar rectangular plate shape, and the length of one side thereof is, for example, about 150 to 450 mm. In this example, the length and width are 300 mm and 450 mm. The thickness T1 is, for example, about 12 to 15 mm, and in this example, 12 mm.

  Moreover, as shown in FIG. 3 (A), the floor finishing material 3 is formed with a recess 5 that can be fitted to the protrusion 4 of the floor sheet S, as shown in FIG. FIG. 3 (A) shows the floor finishing material 3 with the bottom surface up. In this embodiment, the concave portion 5 has a circular shape in accordance with the shape of the protrusion 4, and the opening diameter thereof is substantially the same as that of the protrusion 4. In addition, if the recessed part 5 is formed in the taper hole shape which opened the opening edge side a little, it is preferable at the point from which fitting operation with the projection body 4 becomes easy. Further, it is also possible to provide an inclined fitting guide at the opening edge of the recess 5.

In this embodiment, as shown in FIG. 3A, the recesses 5 are arranged vertically and horizontally at equal intervals P (40 mm in this embodiment). Yes. In addition, when the protrusions 4 of the floor sheet S are arranged in a staggered manner, the concave portions 5 of the floor finish 3 are similarly arranged in a staggered manner at the same intervals as the protrusions 4.

  Further, as shown in FIG. 3A, the concave portion 5 located on the outermost side of the floor covering 3 is formed such that the distance from the outer edge thereof is located at half the distance P between the concave portions 5. . Therefore, the interval between the concave portions 5 and 5 located on the outermost side of the floor finishing materials 3 and 3 continuously fixed to the floor sheet S is equal to the interval P. As a result, the floor covering materials 3 and 3 that are fixed adjacent to each other do not generate a gap therebetween.

  As shown in FIG. 3 (A), the floor finishing material 3 includes a base layer 3B and a decorative layer 3A attached on the base layer 3B. The base layer 3B includes plywood, MDF (medium density fiberboard), particles It is formed using wood materials such as boards and laminated timber.

In addition, the decorative layer 3A is formed by adhering decorative paper for a decorative board to the base layer 3B and then applying an unsaturated polyester resin, and the surface of the base layer 3B is formed of a polyester resin, a polyurethane resin, or an aminoalkyd resin. Alternatively, it may be formed by painting with an acrylic resin or the like.

  In this way, as shown in FIGS. 1 and 2, the floor finishing material 3 is fixed without gaps by fitting the concave portions 5 to the protrusions 4 of the floor sheet S laid on the floor base. Therefore, the floor base and the floor finishing material are blocked by the floor sheet, and the protrusions of the floor sheet and the concave portion of the floor finishing material are fitted together, so that the floor finishing material is fixed without gaps, thereby ensuring the sound insulation performance of the floor. Is done. Therefore, it is not necessary to separately provide a new sound insulation layer on the upper floor, and the first floor and the upper floor can have the same structure. As a result, the types of members constituting the floor can be reduced, the productivity of the members and the floor construction efficiency can be improved, the cost can be reduced, and the performance quality can be stabilized. Moreover, the use of ridges is not used for fixing floor finishing materials, so the production process of building materials is improved by omitting the ridge processing process, and skill in the installation work of floor finishing materials is not required. Floor performance quality is improved.
