(Installation method of floor plate support 22)
The procedure for installing the floor plate 14 above the installation surface 1 by the floor plate support 22 formed in this manner will be described.
First, a case where the bundle main body 3 and the base plate 2 are integrated will be described. As shown in FIG. 1A, the base plate 2 is placed on the installation surface 1, and the space between the base plate 2 and the installation surface 1 is fixed with an adhesive or the like. Then, the shaft member 4 is rotated with respect to the base plate 2, the support plate 8 is roughly lowered to a predetermined position, and the first locknut 9 is tightened with respect to the end face of the bundle body 3. Then, the shaft member 4 is integrally fixed with the bundle body 3. Then, as shown in FIG. 1B, the floor plate 14 is placed on the support block 16 so that the hole 18 and the hole 17 of the support block 16 are aligned. Then, the screwing tool 20 is inserted into the holes 18 and 17 (FIG. 1 (B)), and a hexagonal hole (not shown) formed inside the tool is formed on the polygonal surface 6 of the screwing member 13 of the elevating body 7. It is fitted and the screwing tool 20 is rotated to raise and lower the elevating body 7. As a result, the support plate 8 moves up and down in conjunction with the shaft member 4, and the height level of the floor plate 14 can be finely adjusted.

Then, as shown in FIG. 1C, the second locknut 10 is screwed onto the shaft member 4, and the lower surface thereof is fastened and fixed to the upper surface of the screwing member 13 of the elevating body 7. In this example, a double locknut is used. Then, the decorative board 15 is arranged on the upper surface of the floor board 14, and the installation of the floor board is completed.
In this example, only one floor plate support 22 has been described, but a large number of floor plate supports 22 are arranged at appropriate intervals on the installation surface 1. Then, a hole 18 of the floor plate 14 exists above each floor plate support 22, and the height of the floor plate 14 is adjusted at each portion on the plane through the screwing tool 20. Finally, the decorative board 15 is arranged on the floor board 14.

Next, the case of the second embodiment in which the bundle main body 3 rotates with respect to the base plate 2 will be described. As shown in FIG. 1A, the base plate 2 is placed on the installation surface 1, and the space between the base plate 2 and the installation surface 1 is fixed with an adhesive or the like. Then, while gripping the bundle body 3 so as not to rotate, the shaft member 4 is rotated with respect to the base plate 2, the support plate 8 is roughly lowered to a predetermined position, and the first locknut 9 is attached to the end surface of the bundle body 3. Tighten against. Then, the shaft member 4 and the bundle body 3 are integrally fixed, and both rotate integrally with the base plate 2.

In this state, as shown in FIG. 1B, the floor plate 14 is placed on the support block 16 so that the hole 18 and the hole 17 of the support block 16 are aligned. Then, instead of the screwing tool 20, the holder 25 shown in FIG. 6 is inserted into the hole 18 and the hole 17 and fitted to a part of the polygonal surface 6 of the elevating body 7 to hold the elevating body 7 so as not to rotate. do. Subsequently, the shaft member 4 is rotated (at this time, the bundle body 3 is also integrally rotated with respect to the base plate), and the elevating body 7 is relatively moved up and down. As a result, the support plate 8 moves up and down in conjunction with the shaft member 4, and the height level of the floor plate 14 can be finely adjusted. When the adjustment is completed, the second locknut 10 is screwed onto the shaft member 4, and the lower surface thereof is fastened and fixed to the upper surface of the screwing member 13 of the elevating body 7. The shaft member 4 may be provided with a hexagonal hole or the like on the top surface into which a wrench for screwing the shaft member 4 is inserted.

As shown in FIG. 6A, the shape of the holder 25 is such that the plate body is bent into a crank shape, one end portion is a grip portion 27, and the other end portion is a part of the polygonal surface of the elevating body 7. It has a notch 26 consistent with.
For example, when the polygonal surface of the elevating body 7 is hexagonal, the notch 26 (FIG. 6 (C)) is aligned with at least two opposite sides, or the notch 26 (FIG. 6 (B)) is aligned with the four sides. ))And it is sufficient.

In this example, in FIG. 2, the relatively thin-walled screwing member 13 is caulked and fixed to the stepped portion of the elevating body main body 12 of the elevating body 7. Thereby, even when the plate thickness of the floor plate 14 is relatively thin, the polygonal surface 6 can be rotated or held to take a larger vertical movement of the level adjustment of the floor plate 14.
In FIG. 2, the elevating body main body 12 of the elevating body 7 may have a circular outer circumference or a polygonal shape similar to the screwing member 13. In the case of a polygonal shape, the screwing member 13 and the elevating body main body 12 may be turned upside down.

The floor plate support of the present invention can provide an optimum one capable of finely adjusting the height from the installation surface such as a slab to the floor plate of the building from the floor plate side.
