Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg for a double-floor panel used for supporting a double-floor panel at a predetermined height on a floor surface of a building to construct a double floor.

[0002]

2. Description of the Related Art A conventional double-floor panel support leg has a screw shaft 2 on a base plate 1 as in the first example shown in FIG.
Is fixed upright, a nut 3 is screwed onto the screw shaft 2, and a panel receiver 4 fitted on the upper part of the screw shaft 2 is supported by the nut 3.

The panel receiver 4 is provided with cross-shaped partitioning projections 8 on the upper surface of a rectangular board 7, and corners of the double floor panel are provided at four corners on the board 7 partitioned by the projections 8. The portion is placed and fixed by tapping screws, and the height of the panel receiver 4 is adjusted by rotating the nut 3. After the adjustment, the nut 9 is fixed to the screw shaft 2 by tightening the bolt 9 provided on the nut 3. 3 is fixed, and the panel receiver 4 is fixed to the screw shaft 2 by tightening the bolt 5.

In the second example shown in FIG. 4, a pipe support 6 is erected and fixed on a base plate 1, and a nut 3 supported at the upper end of the support 6 is screwed onto a screw shaft 10 inserted in the support 6. The structure is such that the panel support 4 is fixed to the upper end of the screw shaft 10, and the screw shaft 10 is fixed to the support column 6 with the bolt 9a, and the nut 3 is fixed to the screw shaft 10 with the bolt 9. .

[0005]

By the way, in any of the above-mentioned conventional support legs, the fixing of the nut after the height adjustment and the fixing of the panel support 4 in the plane direction are independent and independent. Since it is done with the bolts, there is a problem that it is difficult to tighten the bolts under the panel.

[0006] Further, the support leg must be set to the thickness of the upper screw shaft 2 and the pipe strut 6 depending on the support height of the panel. However, in the above-mentioned conventional structure, there are many kinds of support legs. In the latter example, the number of types of pipe stanchions increases, and if the number of types is reduced by standardizing the pipe stanchions, special processing is required for the pipe struts. There's a problem.

Therefore, an object of the present invention is to provide a support leg for a double-floor panel in which nuts and panel receivers can be easily fixed, and a structural screw shaft can be commonly used for height changes. Especially.

The flange 22 extends from the lower end to the lower end. Male screw 23 is provided on the outer peripheral surface between
Vertical grooves 24 for preventing rotation are provided on both sides of the shaft center in the range from the middle to the lower end of the portion where the external thread 23 is provided, and the vertical groove 24 is fitted on the inner diameter surface of the holding cylinder 15 for preventing rotation. A ridge 25 is provided.

Therefore, the screw shaft 16 is movable in the vertical direction in the rotation stop state with respect to the holding cylinder 15, and the nut 17 screwed to the screw shaft 16 contacts the upper end surface of the holding cylinder 15 to support it. By rotating the nut 17, the screw shaft 16 moves up and down.
The height position of the panel receiver 18 attached to the upper end of 6 can be adjusted.

The flange 20 of the holding cylinder 15 is provided with a plurality of projections 34 for rotation preventing means on the upper surface where the polygonal nuts 17 overlap with each other, and the outer diameter surface of the nut 17 overlapping with the flange 20 contacts. . Therefore, if the nut 17 is overlaid on the flange 20 after the height adjustment, the rotation stop of the nut 17 with respect to the screw shaft 16 is automatically obtained.

When manufacturing support legs having different support heights with respect to changes in the panel height, the screw shaft 16 is commonly used, the panel support column 13 is set to a diameter capable of obtaining the required strength, and the holding cylinder 15 is provided. It is only necessary to manufacture those having an outer diameter suitable for the panel support only for the types of the pipe support, and the screw shaft through holes 35 provided in each of these holding cylinders may be formed to have an inner diameter suitable for the common screw shaft.

The panel receiver 18 is provided with a planar cross-shaped partition protrusion 27 on the upper surface of a rectangular substrate 26, and a vertical hole that is fitted onto the upper end of the screw shaft 16 at the center of the substrate 26 and the partition protrusion 27. 28 is provided, and the lower end extension is supported by being mounted on the flange 22 of the screw shaft 16 by the peripheral wall of the vertical hole 28.
The cushion material 29 formed in a cross shape using a rubber or the like on the upper end surface of the partition projection 27 has a projection 30 on the lower surface provided on the upper surface of the partition projection 27. By press-fitting into the mounting hole 31, it is fixed in a slip-out preventing manner.

The four places separated by the partitioning protrusions 27 of the substrate 26 become the mounting portions of the double floor panel 32, and the panel 32 is provided with tapping screws in the lower hole 3 of the substrate 26.
It is fixed to the panel receiver 18 by screwing it into 3.

The support leg of the present invention has the above-mentioned structure, and in order to construct the double floor panel, the support leg is located at the position where the ends of the double floor panel gather on the floor surface A of the building. 11 is arranged.

The support leg 11 has the base plate 12 installed on the floor surface A, the pillar member 14 fixed to the floor surface by nailing or adhesion with an adhesive, and stands up.
The holding cylinder 15 is previously fixed to the upper end of 3, and the nut 17
The lower end side of the screw shaft 16 screwed in the middle is inserted into the pipe column 13 from the inside of the holding cylinder 15, and the nut 17 is inserted into the holding cylinder 15.
Place on top of

The screw shaft 16 is held in a non-rotatable state by the holding cylinder 15 by fitting the vertical groove 24 and the projection 25, and the panel receiver 18 is externally fitted and inserted into the upper end of the screw shaft 16 to form a flat surface. The desired direction is determined and fixed to the screw shaft 16 with an adhesive.

In the above state, the height of the panel receiver 18 is adjusted by lifting the screw shaft 16 and rotating the nut 17.
It suffices to move the nut 17 upward or downward, and then
When the nut 17 is placed on the flange 20, the nut 17 has a rotation preventing shape, and the height of the panel receiver 18 can be adjusted.

As described above, after adjusting the height of the panel receiver 18 of each supporting leg 11 arranged on the floor surface, if the double floor panel 32 is fixed on the substrate 26 of each panel receiver 18, A double floor can be constructed on the floor surface A.

[0023]

As described above, according to the present invention, the holding cylinder is inserted and fixed to the upper end of the pipe support erected on the base plate, and the nut is attached to the screw shaft inserted from the holding cylinder into the pipe support in a non-rotating manner. Since the nut rotation prevention means is provided on the nut overlapping surface of the support cylinder and the panel receiver is mounted on the upper end of the screw shaft, simply mount the nut that adjusts the height of the panel receiver on the holding cylinder. Since it has a non-rotating shape, the operation of stopping the rotation of the screw shaft and nut is completely unnecessary, and the double floor panel can be installed smoothly.

Further, since the screw shaft is stopped by the holding cylinder fixed to the panel support and the screw shaft is moved up and down by the turning operation of the nut, the rotation of the panel receiver is generated even if the height is adjusted. Moreover, the height of the panel receiver after the double floor panel is attached can be adjusted without any trouble.

Further, since the holding cylinder is provided at the upper end of the pipe strut, when the screw shaft is made common when manufacturing the supporting legs having different supporting heights, it is only necessary to make the holding cylinder according to the kind of the diameter of the pipe strut. Since the screw shaft can be shared, the cost for manufacturing the support leg can be reduced.
