And a skeleton configured to include: A plurality of ceiling beams 11 are bridged at regular intervals between the upper beams 4 and 6 constituting the skeleton, and a plurality of floor joists 12 are bridged at regular intervals between the lower beams 8 and 10. .

[0003] A ceiling member 23 is attached to the lower surface of the ceiling beam 11 to form a ceiling. Floor joist 1
Particle board 22 is attached to the upper surface of 2,
A plurality of flooring materials 21 are arranged and fixed on the particle board 22 via nails or an adhesive, thereby forming a flooring floor 20.

As shown in FIG. 6, the flooring material 21 has a projection 21A at one end in the width direction and a depression 2A at the other end.
1B, which are arranged and fixed on the upper surface of the particle board 22 without any gap by fitting them between adjacent ones.

[0005]

In the conventional flooring structure, when the particle board 22 and the flooring material 21 are joined via a nail, the thermal expansion of the particle board 22 differs from part to part. A gap is easily generated between the two. Further, the particle board 22 and the flooring material 21 are bonded with an adhesive.
When joining the flooring material 21, it takes time and effort to fit the projections 21 </ b> A and the recesses 21 </ b> B provided on the flooring material 21 and to arrange and fix the flooring materials 21 without any gap. And the replacement of the flooring material 21 becomes difficult.

An object of the present invention is to provide a floor structure of a building and a method for constructing the floor, in which no gap is generated between the flooring materials and the flooring materials can be easily attached and replaced.

[0007]

A floor structure of a building according to the present invention will be described with reference to the drawings. In the building, a plurality of flooring materials 21 are arranged and fixed on a particle board 22 supported by a floor joist 12. In the floor structure of the above, via a synthetic resin foam tape 30 having an adhesive 31 on both sides,
It is characterized in that the particle board 22 and the flooring material 21 are joined. In the present invention, since the synthetic resin foam tape 30 having the adhesive 31 on both surfaces is used, even if the particle board 22 is partially deformed due to a difference in thermal expansion, the deformation is synthesized. Since the resin foam tape 30 absorbs the elastic deformation, no gap is generated between the flooring materials 21. Further, the particle board 22 is provided via the synthetic resin foam tape 30.
And the flooring material 21 are joined to each other, so that the flooring material 21 can be easily attached and replaced as compared with the conventional structure using the entire surface adhesive.

In the above structure, it is preferable that a pressure-sensitive adhesive 31 is used as the adhesive. In this case, the synthetic resin foam tape 30 is
Since the adhesive does not adhere unless a certain pressure is applied, the synthetic resin foam tape 30 attached to the particle board 22 is not used.
By placing the flooring material 21 on the top without pressing, it is possible to accurately position the flooring material 21 while moving it. Thereafter, if the flooring material 21 is pressed toward the particle board 22, the adhesive force of the pressure-sensitive adhesive 31 increases, so that the flooring material 21 can be firmly bonded to the particle board 22.

Further, in the above configuration, it is preferable that the synthetic resin foam tape 30 has an acrylic foam 32 as a base material. In this case, since the acrylic foam 32 is used as the base material, the resistance to plastic materials, weather resistance, water resistance, and chemical resistance can be improved.

Further, in the above configuration, it is desirable that the synthetic resin foam tape 30 is attached in the direction in which the flooring materials 21 are arranged. In such a case, the synthetic resin foam tape 30 may be
, The synthetic resin foam tape 30 maintains the space between the adjacent flooring materials 21, so that no gap is formed between the flooring materials 21.

Further, in the above configuration, it is desirable that the synthetic resin foam tape 30 is attached with a certain gap in a direction perpendicular to the direction in which the flooring materials 21 are arranged. In such a case, when the flooring material 21 is pressed and attached, even if the synthetic resin foam tape 30 is crushed in a direction perpendicular to the arrangement direction of the flooring material 21, the crushing is performed. The portion can be tolerated in the gap portion of the synthetic resin foam tape 30. Moreover, it is possible to economically attach the tape with a small amount of tape.

The method for constructing a floor of a building according to the present invention comprises the steps of:
In a construction method of a floor of a building in which a plurality of flooring materials 21 are arranged and fixed on a particle board 22 supported by a composite material 2, a combination of the particle board 22 and the flooring material 21 having a pressure-sensitive adhesive 31 on both surfaces is provided. It is characterized in that it is temporarily fixed via the resin foam tape 30 and the flooring material 21 is positioned, and then the flooring material 21 is pressed toward the particle board 22 to be joined. When the floor structure is formed by such a method, the synthetic resin foam tape 30 may be used.
Cannot be adhered unless a certain pressure is applied. Therefore, by sticking the particle board 22 and the flooring material 21 through the synthetic resin foam tape 30 without pressing, the positioning is accurately performed while moving the flooring material 21. can do. If the flooring material 21 is pressed toward the particle board 22 after the positioning is completed, the adhesive force of the pressure-sensitive adhesive 31 increases, so that the flooring material 21 and the particle board 22 can be firmly joined.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components as those in FIG. 5 and FIG.
The description is omitted or simplified. In this embodiment, only the structure of the flooring floor 20 is changed in FIG. 5 (the other configuration is not changed). In the flooring floor 20 of the present embodiment, as shown in FIG. 1, the particle board 22 and the flooring material 21 are joined via a synthetic resin foam tape 30 having an adhesive 31 on both sides.

More specifically, a plurality of synthetic resin foam tapes 3 are arranged along the direction in which the flooring materials 21 are arranged and at regular intervals in a direction perpendicular to the direction in which the flooring materials 21 are arranged.
0 is pasted.

As shown in FIG. 2, the synthetic resin foam tape 30 has a band-shaped base material 32, an adhesive 31 applied to both sides of the base material 32, and an outer surface of one adhesive 31. It is wound in a roll shape in a laminated structure with a liner 33 provided so as to be peelable. As the substrate 32, an acrylic foam having excellent plasticizer resistance, weather resistance, water resistance and chemical resistance is desirable. The adhesive 31 is preferably a pressure-sensitive adhesive that does not adhere unless a certain pressure is applied, but increases the adhesive force when pressed with a certain pressure or more.

Next, a method of constructing a floor of a building will be described. Synthetic resin foam tapes 30 are stuck on the particle board 22 supported by the floor joists 12 at a constant pitch, and the flooring materials 21 are arranged in a direction orthogonal to the synthetic resin foam tape 30. At this time, if the flooring material 21 is not pressed from above, the flooring material 21 can be moved.
Positioning is performed while fitting the convex portion 21A and the concave portion 21B provided at one end and the other end in the width direction. After the completion of the positioning, the flooring material 21 is pressed toward the particle board 22 to be bonded.

In this manner, as shown in FIG. 3, a flooring floor 20 in which a plurality of flooring materials 21 are arranged and fixed on the particle board 22 can be formed. Even if a partial difference in thermal expansion occurs in the particle board 22 from this state, the synthetic resin foam tape 30 is elastically deformed and absorbs the deformation as shown in FIG.

According to the above-described embodiment, the following effects can be obtained. Since the particle board 22 and the flooring material 21 are joined via the synthetic resin foam tape 30 having the adhesive 31, the synthetic resin foam tape 30 elastically deforms and absorbs the deformation of the particle board 22. There is no gap between the adjacent flooring materials 21. Also, since the member joining the two is a synthetic resin foam tape 30 having adhesives 31 on both sides,
The flooring material 21 can be easily attached and replaced as compared with the case where an adhesive is applied to the entire surface.

Further, since the pressure-sensitive adhesive 31 is used as the adhesive, the adhesive does not adhere unless a certain pressure is applied, so that the particle board 22 and the flooring material 21 are interposed via the synthetic resin foam tape 30. If it is stuck without pressing, the flooring material 21 can be accurately positioned while being finely adjusted. When the pressure is applied from above the flooring material 21 after the positioning is completed, the adhesive force of the pressure-sensitive adhesive 31 increases, so that the flooring material 21 and the particle board 22 can be firmly joined.

Further, since the synthetic resin foam tape 30 uses the acrylic foam 32 as a base material, it has plasticizer resistance,
Weather resistance, water resistance, and chemical resistance can be improved.
In addition, since the acrylic foam 32 is made of an elastic foam, the walking feeling is softened, and even if an object is dropped on the flooring floor 20, the impact can be buffered, so that the impact sound is reduced. It is possible to do.

Since the synthetic resin foam tape 30 is attached along the direction in which the flooring materials 21 are arranged, the spacing between the flooring materials 21 is accurately maintained,
There is no gap between the flooring materials 21.

At this time, since the synthetic resin foam tape 30 is attached at a fixed interval in a direction perpendicular to the arrangement direction of the flooring materials 21, pressure is applied from above the flooring material 21. When the flooring material 21 is squeezed in a direction perpendicular to the direction in which the flooring materials 21 are arranged, the crushed portion is used as a gap between the synthetic resin foam tape 30 and acceptable. Also, it can be economically applied with a small amount of tape.

Since the synthetic resin foam tape 30 is wound in a roll, the synthetic resin foam tape 30 can be adhered while rolling, thereby facilitating the attaching operation.

Since the liner 33 is detachably provided on one outer surface of the pressure-sensitive adhesive 31 of the synthetic resin foam tape 30, it can be wound into a roll.
Thereby, it can be stored compactly. In addition, when the synthetic resin foam tape 30 is applied, the tape is attached while the liner 33 is peeled off, so that the workability is improved.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment, and various modifications and changes in design can be made without departing from the gist of the present invention. Is possible. For example, this floor structure is not limited to the building unit 1 and may be any floor structure of a building. At this time, the same effect can be obtained by joining in the same manner as in the method described in the embodiment.
