FIG. 3 is a view taken along the line III-III in FIG. 2. Explanatory drawing of assembling the elevating body 7 and the support plate 8. FIG. 5 is a view taken in the direction of arrows VV in FIG. 4. Illustration of the holder to be used in the second embodiment.

Next, an embodiment of the present invention will be described with reference to the drawings.
The floorboard support is, for example, a floorboard support for supporting a floorboard of an office floor in a building and arranging various cables, pipes, and the like in a space under the floor. FIG. 1 is an explanatory view for sequentially explaining a procedure for supporting the floor plate, and FIG. 2 is an explanatory view showing a main part thereof and showing a relationship among a lifting body 7, a support plate 8, and a support block 16. FIG. 3 is a view taken in the direction of arrows III-III in FIG.

  The floor support 22 comprises a bundle body 3 having a base plate 2 at the lower end, the shaft member 4 which is screwed into the internal thread of the bundle body 3, a lifting member 7 which is screwed to the outer periphery of the shaft member 4, the lifting The apparatus includes a support plate 8 that is held by the annular groove 5 of the body 7 and rotates around an axis, and a support block 16 fixed to the support plate 8. Then, the intermediate portion of the shaft member 4 is first locking nut 9 is provided for locking between the shaft member 4 and the beam body 3, the upper end portion of the shaft member 4, the shaft member 4 and the lifting member 7 A second lock nut 10 is screwed at the stage of FIG. 1 (C).

  The floor panel support 22 has a bundle main body 3 formed in a hollow shape, an upper end formed in a slightly thin neck shape, and a female screw formed in the neck. The bundle body 3 has a base plate 2 at the lower end. The external thread of the shaft member 4 is screwed to the internal thread of the neck of the bundle body 3. A first lock nut 9 is screwed between the shaft member 4 and the bundle body 3 in advance.

  Further, a support block 16 is fixed to the support plate 8 supported by the annular groove 5 of the elevating body 7 via screws 19 in advance. As shown in FIGS. 2 and 3, a hole 17 penetrates the center of the support block 16, and the lower surface of the support block 16 is fixed to the support plate 8 via a screw 19 in a screw hole 23 provided in the support plate 8. The support plate 8 has the hole edge of the center hole 11 supported by the elevating body 7. That is, both the upper and lower surfaces of the edge of the center hole 11 are sandwiched by the elevating body 7. The lifting / lowering body 7 includes a lifting / lowering body main body 12 and a screw member 13. That is, in FIG. 4, the center hole 11 of the support plate 8 is fitted in the annular groove 5 of the elevating body main body 12 in advance, and then the screw member 13 is aligned with the pilot portion 21 of the elevating body main body 12 so that the teeth 24 To form the elevating body 7. At this time, there is a gap between the annular groove 5 and the center hole 11 that can rotate around the axis.

(How to install the floor panel support 22)
A procedure for installing the floor panel 14 above the installation surface 1 by the floor panel support 22 thus configured will be described.
First, the 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 base plate 2 and the installation surface 1 are fixed with an adhesive or the like. Next, 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 lock nut 9 is tightened against the end face of the bundle main body 3. Then, the shaft member 4 is fixed integrally with the bundle main body 3. Then, as shown in FIG. 1B, the floor plate 14 is placed on the support block 16, and the hole 18 and the hole 17 of the support block 16 are aligned. Next, a screw tool 20 is inserted into the holes 18 and 17 (FIG. 1B), and a hexagonal hole (not shown) formed inside the tool is inserted into the polygonal surface 6 of the screw member 13 of the elevating body 7. The lifting tool 7 is moved up and down by rotating the screw tool 20. This allows the support plate 8 to move up and down in conjunction with the shaft member 4 to finely adjust the height level of the floor plate 14.

Then, as in FIG. 1 (C), the second locking nut 10 is screwed to the shaft member 4 is fastened to the lower surface to the upper surface of the screw engagement member 13 of the lifting body 7. In this example, a double lock nut is used. Next, the decorative board 15 is arranged on the upper surface of the floor board 14 to complete the installation of the floor board.
In this example, only one floor panel support 22 has been described, but a large number of floor panel supports 22 are arranged on the installation surface 1 at appropriate intervals. The 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 part on a plane via the screw tool 20 therefrom. And finally, the decorative board 15 is arranged on the floor board 14.

  Next, a 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 base plate 2 and the installation surface 1 are fixed with an adhesive or the like. Then, while holding 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 lock nut 9 is attached to the end face of the bundle body 3. Tighten against Then, the shaft member 4 and the bundle main 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 and the hole 18 and the hole 17 of the support block 16 are aligned. Next, a holder 25 shown in FIG. 6 is inserted into the holes 18 and 17 instead of the screw tool 20, and is 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. I do. Subsequently, the shaft member 4 is rotated (the bundle main body 3 also rotates integrally with the base plate at this time), and the elevating body 7 is moved up and down relatively. This allows the support plate 8 to move up and down in conjunction with the shaft member 4 to finely adjust the height level of the floor plate 14. When the adjustment is completed, the second lock nut 10 is screwed onto the shaft member 4, and the lower surface thereof is fastened and fixed to the upper surface of the screw member 13 of the elevating body 7. The shaft member 4 may have a hexagonal hole or the like into which a wrench for screwing the shaft member 4 is fitted on the top surface.

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

In this example, a relatively thin screw member 13 in FIG. 2 is caulked and fixed to the stepped portion of the lifting / lowering body main body 12 of the lifting / lowering body 7. Thus, even when the floor plate 14 has a relatively small thickness, the polygonal surface 6 can be rotated or held, and the vertical movement of the level adjustment of the floor plate 14 can be increased.
2, the lifting body 12 of the lifting member 7 may also be a polygonal shape as well, the screw engagement member 13 to the outer peripheral circular. In case of the polygonal shape may be an elevating body 12 and the screw engagement member 13 upside down.

  The floor panel support of the present invention can provide an optimum one that can level the height from the installation surface of the slab or the like to the floor panel of the building from the floor panel side to fine adjustment.
