DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pad structure for covering the upper surface of a support leg of a floor panel.

[0002]

2. Description of the Related Art A floor panel for free access is provided with a space under the floor between a foundation floor surface and the floor panel.
The corners are supported on the base floor by supporting legs, but generally, the supporting legs and the floor panel are not fixed. However, floor panels are fixed to supporting legs in places where important equipment is installed and in passageways.

FIG. 7 is a perspective view showing a structure for fixing a support leg and a floor panel in a conventional example, and FIG. 8 is a sectional view.
When the floor panel 10 is supported on the foundation floor surface 14 by the support legs 12, the upper surface of the support legs 12 is covered with a pad 18 having an interposed body 16 inserted between the floor panels 10. 10 corners are also supported to prevent slippage.

In this case, the structure of the support legs 12 is such that a circular support board 20 is received by a base 22, and a screw portion 26 a of a support 26 raised on a base 24 is inserted into a screw hole 22 a formed in the base 22. The pad 18 is rotatably attached to the support board 20. Since the base 24 is fixed on the foundation floor surface 14, when the support board 20 is rotated, the height of the support legs 12 is adjusted. Further, since the pad 18 is rotatable with respect to the support board 20, even if the support board 20 is rotated, the pad 1 can be rotated.
The phase angle of 8, that is, the position of the interpolating body 16 can be maintained at a regular position.

For fixing the floor panel 10 and the support legs 12, a notch is formed in a corner of the floor panel 10, and an insertion hole is formed by abutting the corner of each floor panel 10, and an upper hole is formed in the insertion hole. (In the present embodiment, a fan-shaped notch 30 for passing the bolt 28 is provided in a corner portion of the floor panel 10), and a mounting hole ( In this example, the screw is screwed into a screw hole 22b (which is usually smaller in diameter than the screw hole 22a for holding the support 26).

On the other hand, when the floor panel 10 is not fixed to the support legs 12, the use of the support legs 12 is the same, except that the screw holes for fixing the bolts 28 to the base 22 are provided. It is not necessary to provide 22b etc.
For ease of processing, a screw hole 22a through which the column 26 is passed is used to penetrate upward. Also, the floor panel 10 does not require the notch 30 at the corner or the like.

On the other hand, since the height of the underfloor space varies depending on the type and number of devices installed in the room, the change in height includes a type in which the floor panel 10 is fixed to the support legs 12 and a type in which the floor panel 10 is not fixed. This is dealt with by changing the height of the support leg 12. Specifically, columns 2 with different heights
6 is used. However, when the height of the column 26 is increased, the diameter must be naturally increased from the viewpoint of strength.

[0008]

According to the above method, the floor panel 10 and the base 22 have different shapes between the type in which the floor panel 10 is fixed to the support legs 12 and the type in which the floor panel 10 is not fixed. It becomes necessary, and the production efficiency deteriorates. In the case of moving important equipment due to a layout change, the support legs 12 must be changed.
Work efficiency was getting worse. Further, if such a different diameter screw hole is formed in the base 22, the processing cost is increased.

For this reason, the floor panel 10 is
When fixed to the support legs 1
9, an adapter 34 formed with a screw hole 34a for screwing the bolt 28 upward and a screw portion 34b for screwing into the screw hole 22a of the base 22, as shown in FIG.
May be used to fix the floor panel 10. However, also in this method, several types of screws 34b having different diameters must be prepared according to the type of the base 22. The present invention addresses such a problem, and in essence, can be used as a support leg of a type in which a pad has a function of fixing a fixture and a support leg of a type not fixing a floor panel is fixed. It is like that.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a pad structure of a pad which is put on an upper surface of a support leg which also supports a floor panel as a stopper. A mounting hole for attaching a fixing device for fixing the floor panel is formed at a central portion, and a metal fitting detachably attached to the support leg,
A pad structure for a floor panel supporting leg comprising a cap which covers the metal fitting and is detachably attached to the supporting leg is provided.

[0011]

By the above means, the mounting hole is formed in the metal fitting to fix the fixing tool, and the metal fitting is detachable from the supporting leg. It can also be attached to supporting legs that do not. Therefore, it can be used as a supporting leg of a type that fixes a supporting leg that is not fixed, and it is possible to eliminate the distinction between supporting legs.

[0012]

FIG. 1 is a partial cross-sectional side view of a metal fitting, and FIG. 2 is a bottom view. The metal fitting 36 has an elongated shape whose center in plan view swells in a circular shape. Is provided with a notch 38 that opens inward. This notch 38
Is for engaging with the outer periphery of the support board 20,
Can be attached and detached by inserting and removing it from the support board 20 in the lateral direction.
Further, a fixing tool (a bolt in this example) is provided at the center of the metal fitting 36.
Attachment holes (in this example, screw holes) 40 for inserting and fixing 28
Are formed. Therefore, even if the upward lifting force generated by fixing the bolt 28 is applied to the metal fitting 36, the metal fitting 36 can sufficiently withstand the upward lifting force and can freely rotate with respect to the support plate 20.

FIG. 3 is a plan view of the cap, and FIG.
The cap 42 has a disk shape made of resin or the like, and engagement protrusions 46 projecting inward at four lower ends of the side wall 44 are formed. The engaging projections 46 are for engaging the outer periphery of the support board 20, and the cap 42 is put on the support board 20 from above, and the engaging projections 46 are engaged. Accordingly, the cap 42 is also detachable from the support board 20 and has a structure that can freely rotate. A cross-shaped rib 50 whose inside is a space protrudes from the upper surface portion 48 of the cap 42, and covers a portion of the metal fitting 36 with a single line of the rib 50, thereby controlling the position of the metal fitting 36 and preventing the metal fitting 36 from falling off. The mounting hole 40 of the metal fitting 36 and the through hole 51 formed at the center of the cap 42 are prevented from shifting. When the floor panel 10 is laid on the through-hole 51 at the center of the rib 50, a plug 52 whose head height is almost the same as the upper surface of the floor panel 10 is removably inserted. Have been. The stopper 52 prevents the fan-shaped notch 30 of the floor panel 10 from entering the above-mentioned notch 30 and becoming a depression. On the other hand, only the cap 42 is attached to a place where there is no need to fix, and if it becomes necessary to fix it, it can be easily handled by combining with the metal fitting 36.

FIG. 5 shows a combination of the metal fitting 36 and the cap 42, thereby supporting the floor panel 10 in FIG.
FIG. 3 is a cross-sectional view in the −A direction.
a and the back plate 10b, and the height of the rib 50 of the cap 42 is such that the back plate 10b is
2 and the upper surface of the rib 50 so as to receive and support it. Also, a stopper 5 provided at the center of the rib 50
A concave portion 54 is formed around the periphery of 2, and the corner portion of the floor panel 10 also falls into the concave portion 54. That is, the periphery of the notch 30 is formed in the recessed step portion 55 and dropped into the concave portion 54 so that the upper surface of the head and the upper surface of the floor panel 10 are flush when the bolt 28 is passed, and this portion is They are trying to avoid depressions. Further, a ridge 56 is formed in the vicinity of the outer periphery of the upper surface 48 of the cap 42, and enters into the concave groove 58 formed in the corresponding portion of the back plate 10b. Such a structure is for preventing the position of the floor panel 10 from shifting. As described above, when the floor panel 10 is fixed to the support leg 12, the plug 52 is removed, the bolt 28 is inserted into the through hole 51 from above and screwed into the screw hole 40 to fix the floor panel 10. If it is known in advance that the floor panel 10 will be fixed, the plug 52 may not be attached from the beginning.

FIG. 6 shows another embodiment of the fixing structure of the floor panel 10 and the support legs 12, wherein the mounting hole 40 formed in the metal fitting 36 is formed by a stepped groove 60 and a round hole continuous with the groove. 62, and a pin 66 from which a protruding piece 64 protrudes is inserted into the round hole 60 instead of the bolt 28. By doing so, when the protruding piece 64 is aligned with the groove 60 and the pin 66 is inserted into the round hole 62 and turned about one turn,
Since the protruding piece 64 goes around the back side of the groove 60 and is fastened, the fastening operation is quick.

[0016]

As described above, since the present invention has been described above, the following effects can be expected. a) By attaching this pad to a support leg that does not fix the floor panel, it can be used as a fixed type support leg. Therefore, the support legs can be shared for both the non-fixed type and the fixed type, and it is not necessary to arrange the support legs for each type. b) The type in which the floor panel is not fixed and the type in which the floor panel is fixed can be commonly used. In other words, a floor panel of a fixed type in which a cutout is provided at a corner portion can be used as a floor panel of a type that is not fixed as it is. Never be.) c) When the pad is attached and the support leg is used as a fixed type, it is not necessary to apply a different diameter to the base or use an adapter or the like. d) Since all the screw holes of the base and the space below the mounting holes of the fittings can be used as a margin for adjusting the height of the column, the adjustment width is larger than those in which the base is machined with a different diameter or an adapter is used. e) Since the metal fitting acts like a spring washer, the fixing is prevented from loosening when stopped. f) The manufacturing cost of metal fittings is lower than in the case of performing various different diameter processing on the base or using an adapter.
