Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a support leg for a double floor.

[Prior Art] For example, wiring of a computer or the like on the existing floor surface or various pipes is not preferable in terms of walking and aesthetics. Therefore, as shown in FIG. 8, a new floor 3 is constructed on the existing floor 1 via the support legs 2, and the wiring is provided in the space formed between the existing floor 1 and the new floor 3. It is common practice to install pipes.

Conventionally, the support leg 2 is provided on the existing floor 1 as shown in FIG.
The substrate 4 fixed on the upper side, the hollow support column 5 fixed vertically to the center of the upper surface of the substrate 4, the rod 6 screwed with the upper end of the support column 5 and moving up and down in the support column 5, The panel base 7 is attached to the upper end.

In order to construct the new floor 3 on the existing floor 1 by the above-mentioned conventional support legs 2, the support legs 2 are fixed on the existing floor 1 with a space, and the new floor 3 is constructed horizontally. To be,
The rod 6 is rotated to finely adjust the height of the panel base 7, and the panels are sequentially placed and fixed on the panel base 7. At this time, even if the existing floor 1 is slightly distorted, the new floor 3 is installed horizontally because the pillar 5 and the rod 6 are loosely screwed together.

[Problems to be Solved by the Invention] As described above, after constructing a new floor 3, when increasing wiring or piping, or when rewiring or piping, leave existing wiring or piping as it is without removing it. New wiring and piping may be performed. In this case, if the height of the new floor 3 is not increased, wiring and piping are difficult to perform, and in some cases it may not be possible.

However, the conventional support leg 2 may not be able to be raised to a desired height for the newly installed floor 3 because the height adjustment allowance is short.

[Means for Solving the Problem] The present invention is directed to a substrate mounted and fixed on an existing floor surface, and a hollow first fixed vertically on the central portion of the upper surface of the substrate.
A column, a first connecting plate fixed to the upper end of the first column and having an opening formed in the center, and a hollow second insertable into the first column through the opening of the first connecting plate. A pillar and a second bolt fixed to one end of the second pillar and having an opening formed in the center thereof and bolted to the first connecting plate.
A connection plate, a nut fixed to the other end of the second support column and a central portion of the second connection plate, a rod screwed into one of the two nuts, and a panel attached to the upper end of the rod. A first connecting plate and a second connecting plate.
At least one of the bolt holes formed in the connecting plate and the connecting plate is a stupid hole.

Next, one embodiment of the support leg for double floor of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the double floor support leg of the present invention.

As shown in FIG. 1, the double-floor support leg of the present invention comprises a substrate 8 (see FIG. 2) in which a hole 8A is formed, which is mounted and fixed on an existing floor surface, and a substrate 8 of the substrate 8. A hollow first pillar 9 (see FIG. 3) vertically fixed on the central portion of the upper surface, and a first connection plate 10 fixed to the upper end of the first pillar 9 and having an opening 10A formed in the central portion thereof. (See FIG. 2), a hollow second support column 12 (see FIG. 4) that can be inserted into the first support column 9 through the opening 10A of the first connection plate 10, and is fixed to one end of the second support column 12. In addition, the second connecting plate 13 (see FIG. 5), which has the opening 13A formed in the central portion and is bolted to the first connecting plate 10, the other end of the second support column 12 and the center of the second connecting plate 13. Nut 11 (see FIG. 4) fixed to the portion, a rod 14 screwed to either one of both nuts 11, and attached to the upper end of the rod 14. Was the panel board 15 has from (6 see Figure) and. The holes 8 formed in the substrate 8
A is to allow excess adhesive to be applied to the back surface of the substrate 8 to escape to the outside, and to make it possible to visually check whether the adhesive has spread to the back surface of the substrate 8 from the outside. It is formed to accelerate the drying and curing of the.

The first connection plate 10 and the second connection plate 13 have bolt holes 10B,
A plurality of 13B are formed and connected by bolts 16, but at least one of the bolt holes is a stupid hole. This makes it possible to adjust the horizontal position when fixing the second support 12 to the first support 9, and the support is slightly tilted due to the distortion of the existing floor, and as a result, the panel pedestal position is normal. This is so that the panel can be fixed to the panel base at the regular position even if it is slightly displaced from the position.

To construct a new floor on an existing floor with the support legs for double floor of this invention, do as follows. That is, as shown in FIG. 1, with the second support 12 inserted in the first support 9, the first connecting plate 10 and the second connecting plate 13 are connected to each other by the bolt 1
6, the panels are horizontally fixed on the panel base 15, and the new floor 3 is constructed. The fine adjustment of the panel height is performed by rotating the rod 14. For the distortion of the existing floor, the horizontal position is adjusted when the substrate 8 is fixed, the first connection plate 10 and the second connection plate 13 are adjusted. This is dealt with by adjusting the horizontal position of and the clearance between the rod 14 and the nut 11.

On the other hand, if it is necessary to increase the height of the new floor, do the following. That is, as shown in FIG.
So that the pillar 12 projects from the first pillar 9, that is, the first pillar 9.
Upside down from the case shown in the figure, the first connecting plate 10 and the second connecting plate 13 are joined by the bolts 16, the panel is horizontally fixed on the panel base 15, and the new floor 3 is constructed. The fine adjustment of the panel height is performed by rotating the rod 14, and the first connecting plate 10 is used for the distortion of the existing floor.
This is dealt with by adjusting the horizontal position of the second connecting plate 13 and the clearance between the rod 14 and the nut 11.

In this way, if you use the support leg for double floor of this invention,
Compared with the conventional double-floor support leg, the adjustment allowance for the height of the newly installed floor can be made longer. That is, while the conventional height adjustment allowance is about the length of the rod 14, according to the double floor support leg of the present invention, the length of the rod 14 and the second
This is the total length of the columns 12.

[Effects of the Invention] As described above, according to the present invention, when the newly constructed double floor needs to be raised later due to an increase in the amount of wiring, etc., the initially installed support device is removed. The height can be adjusted significantly without having to re-install a new high support device, and the horizontal position of the panel base caused by the distortion of the existing floor can also be adjusted by the connecting plate when changing the height. Adjusted and extremely dimensionally accurate panels can be easily re-installed, which is extremely useful in terms of both economical efficiency and functionality.
