Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a support device for a free access floor constituting a double floor for OA cable wiring.

[Prior Art] A conventional free access floor for a low floor is of a laid type in which a supporting leg 1 and a panel 2 are integrated as shown in FIG. 7 (see JP-A-63-150476 as a prior art document). .),
As shown in FIG. 8, a laid type in which the adjustable support leg 3 and the panel 4 are integrated (as a prior art document, Japanese Utility Model Publication No. 63-635).
There is No. 8 bulletin. ), A support leg separation type in which the panel 6 is supported by the level adjustable support legs 5 as shown in FIG. 9 (as a prior art document, Japanese Utility Model Laid-Open No. 63-177537).

[Problems to be solved by the device]

By the way, the laid type shown in FIG. 7 cannot cope with unevenness of the concrete floor, and there is a problem in the amount of wiring in the space below the panel 2.

In addition, the floor laying type of FIG. 8 can cope with the unevenness of the concrete floor, but it takes time and effort to loosen the nut 3a and adjust the screw type support legs 3 at the four corners of the panel 4, Poor workability.

Further, in the support leg separation type shown in FIG. 9, the pedestal up / down nut 5b is adjusted by loosening the pedestal up / down nut 5b and the level adjusting nut 5c under the pedestal 5a for receiving the panel 6. Since the level adjusting nut 5c was fixed to the support leg 5, it could not be used when the floor height became low,
The workability has deteriorated.

Therefore, the present invention is intended to provide a support device for a free access floor, in which the level of a pedestal for receiving a panel can be easily adjusted and fixed even in a low floor free access floor.

[Means for Solving the Problems]

One of the supporting devices for a free access floor of the present invention for solving the above-mentioned problems is a supporting leg having a screw on the outer periphery fixed upright on a base plate and having a vertical groove,
It comprises a panel receiving pedestal having a nut that is screwed into the screw of the supporting leg, and a cotter or pin that fits into a vertical groove of the supporting leg when the nut of the panel receiving pedestal is screwed into the supporting leg.

In addition, another one of the supporting devices for the free access floor of the present invention
One is that at least one vertical groove is provided on the inner circumference of the nut of the panel receiving pedestal.

[Action]

The support device for a free access floor of the present invention constructed as described above is arranged on a concrete floor in a predetermined arrangement, and a panel receiving pedestal is required by rotating a nut of the panel receiving pedestal screwed to a supporting leg having a screw on the outer periphery. To the level of
After the adjustment, the cotter or pin is driven into the vertical groove of the support leg to fix the panel receiving pedestal, and the floor panel is placed and arranged on the panel receiving pedestal to efficiently construct a flat free access floor. it can.

Especially when at least one vertical groove is provided on the inner circumference of the nut of the panel receiving pedestal, the rotation of the nut of the panel receiving pedestal is reliably suppressed, and the panel receiving pedestal is securely fixed at the required level position. To be done.

〔Example〕

An embodiment of the supporting device for the free access floor of the present invention will be described with reference to FIGS. 1 and 2, 10 is a base plate,
A supporting leg having a screw 11 on the outer periphery on the base plate 10.
12 are fixed upright. A vertical groove 13 is formed on the outer periphery of the support leg 12. The support leg 12 has a through hole 14 in the center.
A nut 15 for fixing the panel receiving pedestal 14 having a to the upper surface by welding (may be caulking) is screwed. Support leg
A cotter 16 is driven into the vertical groove 13 on the outer periphery of 12 to fix the panel receiving base 14. Incidentally, cotter 16
A head 16a is provided on the to facilitate hitting and pulling out.

When the free access floor supporting apparatus of the embodiment thus constructed is constructed, the free access floor supporting apparatus is vertically arranged on the concrete floor F at a predetermined interval as shown in FIG.
Panel support pedestal 14 is arranged by rotating nut 15 of panel support pedestal 14
Is adjusted to a required level, and after the adjustment, the rotation of the nut 15 is suppressed by a simple operation of driving the cotter 16 into the vertical groove 13 of the support leg 12 to fix the panel receiving pedestal 14 at a required level position.

By placing the floor panels P on the panel receiving pedestal 14 and arranging them in a flat manner, the free access floor can be constructed efficiently.

Further, since there is only the nut 15 on the lower side of the panel receiving pedestal 14 on which the floor panel P is placed, the pedestal up / down nut 5b is provided on the lower side of the pedestal 5a for receiving the panel 6 as in the conventional supporting device shown in FIG. , Unlike the one with level adjustment nut 5C,
Since the level adjustment range of the panel receiving pedestal 14 is large and the panel receiving pedestal 14 can be lowered, it is suitable as a supporting device for a low floor free access floor.

In Fig. 3, the nut 15 of the panel receiving base 14 is turned upside down,
That is, with the panel receiving pedestal 14 on the lower side, the nut 15 is supported.
This is an example in which the floor panel P is screwed to the 12 and fixed by the cotter 16, the floor panel P is placed low from the beginning, and a lower floor free access floor is constructed.

It should be noted that the vertical groove 13 to be cut on the support leg 12 of the support device for the free access floor may be one as shown in the figure if it is in the same direction as the marking line at the time of construction, but a plurality of vertical grooves may be used. Is.

In the above embodiment, the cotter 16 is driven in the vertical groove 13 of the support leg, but a pin may be driven in.

The support device for the free access floor shown in FIGS. 4 and 5 has a vertical groove 13 formed on the outer periphery of the support leg 12 to form a panel receiving pedestal.
After the vertical groove 17 is provided in the through hole 14a of 14 and the equiangular square of the inner periphery of the nut 15, the panel receiving base 14 is level-adjusted, and then the supporting leg 12
The vertical groove 13 is aligned with the closest vertical groove 17, and a coater 16 'having a long front and rear width is driven into the vertical grooves 13 and 17 to fix the panel receiving base 14.

According to the support device for the free access floor, the rotation of the nut 15 of the panel receiving pedestal 14 is not reliably pressed and lowered, so that the panel receiving pedestal 14 can be reliably fixed at a predetermined level position.

FIG. 6 shows an example in which the nut 15 of the panel receiving pedestal 14 shown in FIG. 4 is turned upside down and screwed into the support leg 12, and the floor panel P is placed low from the beginning to construct a lower floor free access floor. Is.

[Effect of device]

As can be seen from the above description, the support device for the free access floor of the present invention has a predetermined arrangement on the concrete floor, and by rotating the nut integrated with the panel receiving pedestal to be screwed to the supporting leg having the screw on the outer circumference, The panel receiving pedestal can be easily adjusted to the required level, and the cotter or pin can be driven into the vertical groove on the outer circumference of the support leg or into the vertical groove on the inner circumference of the nut that is integral with the vertical groove and the panel receiving pedestal. Since the pedestal can be easily fixed to the required level position, workability is extremely good.

Therefore, the floor panels can be placed and arranged to efficiently construct a flat free access floor.

Further, the support device for a free access floor of the present invention is extremely useful as a support device for a low floor free access floor because the level adjusting range of the panel receiving pedestal in the support leg is large.
