Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure and a floor construction method in which floor materials are connected using a connecting tool.

[0002]

2. Description of the Related Art A floor is constructed by arranging a large number of floor materials on a floor slab, and wood flooring is preferably used as a floor finishing material.

FIG. 10 is a diagram showing a general floor structure. In the figure, (A) is a floor slab, and (20) is a floor material. The floor material (20) has male seeds (20a) and female seeds (20b), the male seeds (20a) are meshed and joined with the female seeds (20b) of the adjacent floor material, and the adhesive is applied to the floor slab. It is fixed.

However, in such a floor structure, the work of attaching the floor material such as the engagement of the real parts is troublesome and time-consuming. If the fixing position is misaligned, it is difficult to correct it after the adhesive is cured. In addition, when used, rattling occurs in the meshing of the real parts, and floor squeaking due to squeaking of the real parts is likely to occur.

FIG. 11 is a view showing a conventional floor structure in consideration of soundproofing. In the figure, (F) is a floor material comprising a floor substrate (21), a decorative board (22) and a cushioning material (23). . When this structure is adopted,
The impact on the floor is mitigated by the compression of the cushioning material (23), and it is difficult to transmit it to the floor slab (A). Further, since the adjacent floor materials are not actually connected to each other, the propagation of vibrations to the adjacent floor materials is reduced, and the floor noise due to the squeak of the actual portion does not occur.

However, in this structure, when a heavy object (M) is placed on the floor, only the floor plate on which the heavy object (M) is placed lowers the floor surface due to compression of the cushioning material (23) and is adjacent to the floor plate. This creates a step between the floor and the floor, which causes the appearance to deteriorate and causes a stumble.

Further, in recent companies, offices and the like, OA equipment wiring such as a telephone line and a printer cable of a personal computer may be passed under the floor, but it is difficult to remove the floor material once fixed in each floor structure described above. Moreover, there is no space for wiring under the floor. Therefore, conventionally, in order to perform such wiring processing, wiring is performed between the upper floor and the lower floor as a double floor. However, if a double floor is used, not only will it be time-consuming and costly to construct, but it will also be necessary to consider the clearance between the ceiling and the floor due to the rise of the floor and the change in the door mounting position.

[0008]

Therefore, there is a demand for a floor structure in which floor materials can be easily attached and detached. In addition to this, a floor structure having a soundproof effect and a floor structure in which wiring under the floor is easy are required. It has been demanded.
