Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to support legs for supporting a floor panel of a floor panel type that constitutes a double floor in a computer room or the like.

0002

2. Description of the Related Art Conventionally, as shown in FIG. 4, this type of support leg has a base plate 22 fixed to the lower end of a column 21 having a male thread formed on its outer circumferential surface, and a level adjustment nut 23 attached to the upper end of this column 21. There is a structure in which a panel holder 24 is fixed to the upper end of the level adjustment nut 23 which is screwed together.

[0003] The height of the support leg can be adjusted by rotating a level adjustment nut 23 with respect to the support column 21.

0004

[Problems to be Solved by the Invention] By the way, in the above support leg, since the level adjustment nut 23 is screwed onto the male thread of the support 21, there is an unavoidable gap between the female thread of the level adjustment nut 23 and the male thread of the support 21. Conventionally, this play has been eliminated by forming a through screw hole 25 in the side wall of the level adjustment nut 23, and inserting a fixing screw 26 into this through screw hole 25.
This is prevented by screwing them together.

However, since the level adjustment nut 23 is integrally fixed to the panel holder 24, the level adjustment nut 23 is fixed to the panel holder 24.
4 is directly transmitted to the level adjustment nut 23. Therefore, when an impact is applied to the panel pedestal 24 due to walking or the like, the fixing screw 26 of the level adjustment nut 23 quickly loosens.

[0006] When the fixing screw 26 is loosened, play occurs between the level adjustment nut 23 and the support column 21, causing a problem that when walking on the floor panel A, the floor makes a noise.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a support leg having a structure in which the fixing screw of the level adjustment nut is unlikely to loosen.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention fixes a base plate 2 to the lower end of the pillar 1, forms a male thread on the outer peripheral surface of the pillar 1, and fixes the base plate 2 to the lower end of the pillar 1. A level adjustment nut 3 is screwed onto the male thread of the surface, and a cylindrical portion 4 of a size that is spaced a predetermined distance from the outer circumference of the support 1 is integrally provided on the upper surface of this level adjustment nut 3. Fit the lower end of the pipe support 5 between the inner peripheral surface of the pipe support 5 and the outer peripheral surface of the support support 1, fix the panel holder 6 to the upper end of the pipe support 5, and attach the level adjustment nut 3 to the side wall of the pipe support 5. Through screw holes 7 and 8 are formed respectively, and fixing screws 9 and 10 are screwed into these through holes 7 and 8, respectively.

[0009]

[Operation] By adopting the above structure, the panel holder 6 and the level adjustment nut 3 are separated, and the impact applied to the panel holder 6 is transmitted to the level adjustment nut via the pipe support 5 fixed to the support 1. 3, the fixing screw 9 of the level adjustment nut 3 is difficult to loosen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the support leg according to the present invention will be described below with reference to the accompanying drawings.

A base plate 2 is fixed to the lower end of the column 1. A male thread is formed on the outer periphery of the support column 1 . A through hole 13 is formed in the center of the base plate 2, and an annular platform 11 that bulges upward is formed around the through hole 13. A through hole 1 corresponding to the through hole 13 is provided on the back surface of the annular platform 11.
An annular reinforcing plate 12 having a number 3 formed thereon is fitted therein. A fixing portion 14 that is pushed into the through hole 13 of the base plate 2 and the through hole 13 of the reinforcing plate 12 is formed at the lower end of the support column 1 . Further, above the fixing part 14, a flange part 1 that comes into contact with the upper surface of the base part 11 of the base plate 2 is provided.
5 is formed, and by caulking the fixing portion 14, the column 1, the base plate 2, and the reinforcing plate 12 are integrally coupled. The support 1, the base plate 2, and the reinforcing plate 12 may be joined together by welding.

A level adjustment nut 3 is screwed onto the support column 1. As shown in FIG. A cylindrical portion 4 having a size that is spaced a predetermined distance from the outer peripheral surface of the support 1 when the level adjustment nut 3 is screwed onto the support 1 is integrally provided on the upper surface of the level adjustment nut 3 . Further, a through screw hole 7 is formed in the side wall of the level adjustment nut 3, and a fixing screw 9 is screwed into this through screw hole 7. By screwing together the fixing screw 9 and pressing its tip against the outer surface of the support column 1, the level adjustment nut 3 is fixed to the support column 1 in a non-rotatable manner without wobbling.

The lower end of the pipe support 5 is fitted between the inner peripheral surface of the cylindrical portion 4 of the level adjustment nut 3 and the outer peripheral surface of the support support 1. A through screw hole 7 is formed in the side wall of this pipe support 1, and by screwing a fixing screw 9 into this through screw hole 7 and pressing its tip against the support 1,
The pipe support 5 can be fixed to the support 1. Further, a panel holder 6 is fixed to the upper end of the pipe support 5. The panel holder 6 is formed in a circular shape, and has a through hole 16 formed in its center, into which the upper end of the pipe support 5 is inserted. The panel pedestal 6 and the pipe support 5 are integrally connected by caulking. Further, the periphery of the through hole 16 of the panel holder 6 is formed to be depressed downward.

It should be noted that a vibration-proof and sound-proof sheet 17 made of an elastic material such as rubber is pasted on the top surface of the panel holder 6. In addition, on the top surface of the panel holder 6,
It is desirable to provide an appropriate engagement portion such as a protrusion or claw that engages with the lower surface of the floor panel A.

The support legs constructed as described above are installed at the four corners of the lower surface of the floor panel A, as shown in FIG. 3, and the installation procedure is as follows. First, the base plate 2 is fixed to a floor surface such as concrete using an adhesive or the like. Next, the level adjustment nut 3 is rotated to perform level adjustment, and then the fixing screw 9 is tightened to fix the level adjustment nut 3 to the support column 1. Thereafter, the lower end of the pipe support 5 is inserted into the cylindrical portion 4 of the level adjustment nut 3, and the fixing screw 10 is tightened to fix the pipe support 5 to the support 1.

[0016]

As described above, according to the present invention, the fixing screw 9 of the level adjustment nut 3 is hard to loosen, so that floor noise is hard to occur over a long period of time.

Furthermore, a reinforcing plate 1 is provided on the back surface of the base plate 2.
By combining 2, the strength at the attachment portion between the lower end of the support 1 and the base plate 2 is strengthened, and the load bearing capacity is improved.
