Description of the Related Art Conventionally, when flooring a floor material at a predetermined height position on a floor surface, as shown in FIGS. 6 and 7, after applying a mortar 2 to a floor surface 1a of a building frame 1, , A synthetic foam resin plate 4 in which a large number of wooden vertical bars 3 are embedded in parallel at predetermined intervals on the upper surface is laid on the mortar 2, and then the synthetic foam resin plate 4 is orthogonal to the vertical bars 3. A plurality of wooden horizontal rails 5 are arranged in parallel at predetermined intervals along the direction in which the lower plate 6 is placed on the horizontal rail 5, and the lower plate 6 is attached to the horizontal rails 5 and the vertical bars. After fixing to the crosspiece 3 with nails 7, the lower plate 6
The floor material 8 is fixed on the top with an adhesive or a nail. In addition, in FIG. 6, 9 is a side wall material provided along the side surface 1b of the building frame 1.

[0003]

In the conventional floor covering method described above, since the floor material 8 is stretched on the floor surface 1a, the floor surface 1a is
Mortar 2, synthetic foam resin plate 4 with vertical rails 3 and horizontal rails 5
As the number of steps for flooring is large, it takes a lot of work to prolong the construction period, the construction cost is high, and the synthetic foamed resin plate 4
Is elastically deformed and the floor material 8 is bent vertically and horizontally, so that so-called floor noise is likely to occur.

Therefore, a large number of floor material supports are arranged at predetermined intervals on the floor surface 1a, and a plurality of joists are fixed in parallel on each floor material support at predetermined intervals. It is conceivable that the lower plate 6 is placed on each joist, and the bottom plate 6 is fixed to the joist, and then the floor material 8 is fixed to the bottom plate 6 with an adhesive or a nail. However, this also has the drawbacks that the number of parts is increased by the amount of the joist necessary and that the joist and the floor support are rubbed with each other and an unpleasant frictional noise is easily generated.

In view of the above-mentioned drawbacks, the present invention makes it possible to easily perform flooring with a small number of steps, so-called floor noise does not occur, and the number of parts is small, and unpleasant friction noise is not generated. It is an object of the present invention to provide a floor material support tool.

[0023]

According to the first aspect of the present invention, since the joist is not interposed between the floor support plate and the lower plate, the number of parts is reduced by the amount of the non-interlocked joist, and the construction cost is reduced. In addition to being cheaper, vibration is transmitted to the legs due to an external load such as a heavy load from the floor material because the floor-mounting elastic plate is placed between the legs and the floor. Also, there is no fear that the floor joist will be rubbed against the floor support plate and an unpleasant frictional noise will be generated as in the conventional case. Moreover, flooring can be performed easily with a small number of steps.

Further, the elastic plate for placing on the floor is simply placed on the floor and is not adhered at all, and the restriction is that the lower plate fixed to the floor support is stretched. Since this is done indirectly, flooring construction will be much easier from this aspect as well.

According to the second aspect of the present invention, the stopper screw causes the floor material to be loosened due to the looseness between the male screw portion and the nut portion due to the weight of the heavy object loaded on the floor material during use. Prevents floor material from sagging even after long-term use.

According to the third aspect of the present invention, even if the floor material is vibrated or impacted by the weight of the heavy object loaded on the floor material, these external loads are absorbed by the elastic plate and There is no fear that an unpleasant frictional noise will be generated between the floor material support which supports this.
