Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material for a building and a floor structure using the floor material.

[0002]

2. Description of the Related Art Floor materials are laid on the floor of a building, and the floor materials are generally elongated plate-like long members having a rectangular cross section, which are arranged without gaps. And a nail is driven in from the upper surface and fixed. Therefore,
The head of the nail is exposed on the upper surface of the flooring material. Of course, the head can be buried, but this would make the construction difficult and inevitably increase the cost.

[0003] Each of the slender flooring materials is nailed independently, but it is only in contact with the adjacent flooring material and has no connection to restrain each other. It often expands and warps when it takes on. FIG. 4 shows a case in which a conventionally used flooring material is attached to the groundwork. There are two types of flooring materials, one flooring material A has concave grooves on both sides thereof, and the other flooring material B has side grooves. A convex part is formed in the part. And each of these flooring materials i, b,
A and B are alternately arranged and fixed, but the concave portions of the floor material A are connected by fitting the convex portions of the floor material B.

A nail is driven into the ground from the corner of the concave groove of the floor material a and fixed, but this corner often breaks when nailing. On the other hand, when these flooring materials A, B, A, and B are arranged and fixed on the floor, a slight gap may be generated between the flooring material and the wall surface later due to shrinkage of the flooring material. It is not easy to adjust the width of the floor material so that no gap remains between the floor material and the floor material.

[0005]

As described above, the conventional flooring materials have the above-mentioned problems. The problem to be solved by the present invention is this problem, in which the head of the nail is not exposed on the surface, the floor is not easily deformed even when the floor material is deformed and the construction is simple. Provides wood and floor structure. Further, the present invention provides a floor structure in which no gap is generated between the wall and the wall.

[0006]

SUMMARY OF THE INVENTION There are two types of flooring materials of the present invention, one of which has a concave groove formed on both sides over the entire length. The other one is provided with convex portions on both sides over the entire length. When the side portions of both floor materials are arranged in abutting relation, the convex portions can be fitted and connected to the concave grooves.
In this case, the floor material having a concave groove formed on the side portion extends the fastening piece outward, nails and fixes it, and the convex portion fits into the groove on one of the fixed floor material side portions. The other floor material will settle.

Therefore, the other flooring need not be directly nailed to the floor. Also, each flooring is provided with a slit groove to prevent warping, and one of the nailed floors is fixed in contact with a base such as concrete, while the other flooring interposed therebetween is the bottom surface. Has a slight gap with the base. The floor will be constructed by arranging each of these flooring materials, but a baseboard will be attached to the walls and corners to cover the side edges of the flooring so that no gaps remain in the corners I have. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 is an embodiment showing a flooring 1 according to the present invention. It is a long and thin material having an integral thickness, concave grooves 3, 3 are formed on both sides over the entire length, and fastening pieces 4, 4 are provided below the concave groove 3 so as to protrude outward. I have. Also, narrow slit grooves 5, 5 extend upward from the bottom, and the slit grooves 5 also extend over the entire length of the flooring 1. The slit grooves 5, 5 are for preventing the floor material 1 from warping, and may not be provided at times, and the number of slit grooves is not limited to two as shown in FIG.

FIG. 2 is an embodiment showing the other floor material 2.
Since the flooring 2 is laid in a state of being connected to the flooring 1, convex portions 6 are formed on both sides over the entire length. The position of the convex portion 6 is the central portion of the plate thickness, and can be fitted into the concave groove 3 provided on the side surface of the flooring 1.
And two slit grooves 5,5 extend upward from the bottom,
It is formed over the entire length.

FIG. 3 is a cross section of a floor structure formed by using the floor materials 1 and 2 described above. Are alternately arranged on the floor, and baseboards 7 are attached to the corners of the wall surface. The flooring 1 is fixed to the concrete foundation 8 by nailing one of the fastening pieces 4 formed on both sides thereof, and the groove 3 formed on the side of the flooring 1 has the groove 2 of the flooring 2. Convex part 6
Will fit.

The opposite convex portion 6 of the floor material 2 fits into the groove 3 of another floor material 1, and the fastening piece 4 of the floor material 1 is nailed. In this way, the flooring materials 1 and the flooring materials 2 are alternately arranged and connected by fitting the convex portions 6 into the concave grooves 3, and the one-side fastening pieces 4 of the flooring material 1 are fixed by nailing. That is, the floor material 2 is only sandwiched between the floor materials 1, 1 on both sides, and is not nailed.

As is apparent from FIG. 1, the flooring 2 has a small gap 10 between the bottom 9 and the concrete base 8 without the bottom 9 being in contact with the concrete base 8. That is, the thickness of the floor material 2 is smaller than that of the floor material 1, and a gap is left between the bottom 9 and the concrete foundation 8. Therefore, even if the concrete base 8 is not a perfectly flat surface, the floor members 1, 2, 1,. That is, even if the concrete shrinks and deforms, and the floor material shrinks and deforms, the gap 10 does not cause unevenness on the floor surface.

The baseboard 7 is attached to a corner between the wall and the floor, and a stepped recess 11 is provided below the baseboard surface. The side of the flooring 1 is fitted into the stepped recess 11 so that there is no gap between the flooring 1 and the baseboard 7. The baseboard 7 is nailed against the wall 12 with the lower end in contact with the concrete foundation 8, and the upper surface 13 of the flooring 1 is fitted into the stepped recess 11 without any gap. Some space is left between them. Depending on this remaining space, a plurality of flooring materials 1,
.. Can be adjusted when 2, 2,... Are arranged.

By the way, one flooring material 1 is nailed and fixed to a concrete foundation 8, while the other flooring material 2 is fixed.
Since the is not directly nailed, an adhesive is applied and fixed to the fitting surface between the concave groove 3 and the convex portion 6 to exhibit a strong connection structure. The surface in contact with the concrete base 8 is subjected to insect and termite treatment. As described above, the floor structure of the present invention is a structure in which floor materials are engaged with each other and fixedly arranged, and the following effects can be obtained.

[0015]

The floor of the present invention is constructed by alternately arranging two types of flooring materials. A groove formed on one flooring material side has a convex portion on the other flooring material side. Are fitted and connected, the floor surface becomes a uniform surface without irregularities. Only one of these flooring materials is nailed, and the installation work of the flooring material is simplified. Further, the floor material having the concave groove has a fixing piece protruding outward below the concave groove, and the floor material side portion is broken in order to nail the fixing piece. Does not occur.

On the other hand, the thickness of the other floor material which is not nailed is small, and a small gap is left between the floor material and the floor material. I can do it. Further, a baseboard is attached to the boundary with the wall surface, and no gap is formed in the corner portion by fitting the side portion of the flooring material into the stepped recess formed below the baseboard.
