BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg device for a free-access floor panel, which firmly locks the floor panel horizontally regardless of the ups and downs of the soil and easily raises it. The present invention provides a supporting leg device capable of adjusting the height.

[0002]

[Conventional technology and problems to be solved] Concrete
A double structure in which a large number of floor panels are laid above the soil such as a floor and a free space is secured between the floor panel and the soil so that cables and ventilation ducts can be arranged, that is, a free structure.
The access floor is known.

Among the above-mentioned free access floors, the raised floor type uses independent support legs which are separate from the floor panel, but the soil of a building such as a building is not necessarily formed in a uniform plane. However, there are uneven portions and inclined portions.

Even in the case of conventional support legs, in the case of gentle unevenness of the soil over a wide area, it was possible to correct it by adjusting the height, but it was tried to adjust the unevenness in a narrow area. Then, the panel pedestal was not horizontal due to the inclination of the supporting leg device, which made it difficult to construct the floor panel. In particular, the degree of unevenness in the soil is increasing with the recent spread of free access floors, and it has been demanded to provide a supporting leg device capable of easily constructing a floor panel horizontally even if there is some unevenness. .

[0005]

According to the present invention, in a floor panel support leg device 8 comprising a base 1, a support leg bolt 3 and a panel support 4, a support leg support 2 of the base 1 is provided. The support leg bolt 3 has a fitting recess, and the support leg bolt 3 has a hexagonal hole or a screw hole 11 for rotation in the upper part, and the support leg bolt 3 is screwed into the panel pedestal 4. There is a through hole for inserting a support leg bolt rotation jig in the center of the upper surface of the screw hole of the panel receiving base 4, and the inner diameter of the fitting recess of the supporting leg receiving base 2 is the support leg. A floor panel support leg device 8 is provided, which is slightly larger than the diameter of the bolt 3, and further, the fitting recess of the support leg pedestal 2 is cylindrical. A support leg device 8 is provided, and also the panel support. Table 4 narrowing scissors floor panel 7 in the panel fixing plate 5 and the panel fixing bolts 6, said floor panel support leg 8, characterized in that a structure for fixing are provided.

That is, the supporting leg device of the present invention has a base portion 1
Since the inner diameter of the fitting recess provided in the support leg cradle 2 is larger than the diameter of the support leg bolt 3, when both are fitted,
Since there is a gap 14 in the fitting part, the support leg bolts 3 can be kept vertical even if the base part 1 is not horizontal due to the unevenness of the dirt floor 13, and the panel support 4 and the panel support 4 are arranged above it. The inventors have found that the floor panel 7 according to the present invention can be installed horizontally and have reached the present invention.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a mode of using the floor panel support leg device 8 of the present invention, and FIG. 2 is a cross-sectional view showing a form of using the same support leg device 8 as in FIG. 1 in an inclined dirt floor 13. FIG. 3 is an exploded perspective view of the floor panel support leg device 8 of the present invention. The base portion of the floor panel support leg device 8 of the present invention has a support leg receiving base 2 on the upper portion thereof, and the support leg receiving base 2 has a recess for fitting the support leg bolt 3. The shape of the fitting recess depends on the shape of the lower portion of the support leg bolt 3, but it is usually cylindrical or cylindrical, and the lower portion is preferably a hemispherical shape. In addition,
In the present invention, it is necessary to make the inner diameter of the fitting recess slightly larger than the diameter of the support leg bolt 3. However, when the support leg bolt 3 is fitted in the fitting recess, the clearance 14 formed is 1 to 1. It is preferable that the thickness is about 5 mm. If the clearance 14 is smaller than 1 mm, the region in which the inclination of the support leg bolt 3 can be adjusted is small, which is not very effective.
Further, if it exceeds 5 mm, stable support cannot be performed, which is not preferable. The depth of the fitting recess is usually 10 to 50.
If the depth is less than 10 mm, the supporting leg bolts 3 are likely to come off due to vibration such as an earthquake.
The range in which the tilt can be adjusted is narrowed, and this is not preferable because it has no effect on the actual adjustment of unevenness.

The support leg bolt 3 is used by fitting it into the fitting recess of the base receiving portion 2, and the hexagonal hole or screw hole 11 on the upper part of the support leg bolt 3 is rotated to rotate the floor. It has a structure capable of adjusting the height of the panel 7.

The panel pedestal 4 has a structure in which the floor panel 7 can be placed on its support surface, and has a screw hole into which the above-mentioned support leg bolt 3 is screwed in at substantially the center thereof. The shape of the support surface is not particularly limited as long as a through hole for inserting the support leg bolt rotating jig is provided in the center of the upper surface of the support surface. Further, the projections 9 are provided at the four corners of the support surface of the panel pedestal 4 so that the floor panel 7 does not fall off the panel pedestal 4 in the event of an earthquake or the like and does not rotate with the rotation of the support leg bolts 3. , The corner portion 12 of the floor panel 7
It is also possible to have a structure that can engage with the panel hole 10 provided at the end. In addition, the through hole provided in the central portion of the upper surface of the screw hole of the panel pedestal 4 is integrated with the screw hole, the panel fixing plate 5 is arranged on the upper surface of the floor panel 7, and the panel fixing bolt 6 is tightened. It is particularly preferable that the floor panel 7 is sandwiched and fixed by the panel pedestal 4 and the panel fixing plate 5 in order to stabilize the floor surface.

For the purpose of facilitating the transportation of the support leg device 8 of the present invention at the time of construction, the base portion 1 and the support leg bolt 3 are attached from the rear surface of the base portion 1 by using the engaging bolts 3-1. It can also be integrated. In this case, the structure is such that the engaging bolt 3-1 is tightened so that the head part of the bolt 3-1 slightly floats, and the supporting leg bolt 3
It is necessary to have a structure that allows free rotation.

The floor panel support leg device 8 of the present invention is constructed as follows, for example. First, the support leg bolts 3 are fitted into the fitting recesses provided in the support leg receiving base 2 of the base 1, and in some cases, the base 1 can be joined with the engaging bolts 3-1.
And the support leg bolt 3 are integrated. Then, after the panel support 4 is screwed into the support leg bolt 3, the floor panel 7 is placed on the support surface of the panel support 4. After each floor panel 7 is placed, the supporting leg bolts of the panel receiving base 4 are inserted into the hexagonal holes or the screw holes 11 of the supporting leg bolts 3 from the through holes for inserting the supporting leg bolts, and the supporting leg bolts are inserted. Rotate 3 to adjust the height. Then, the floor panel 7 is fixed by the panel fixing plate 5 and the panel fixing bolt 6 to complete the free access floor construction. Height adjustment after construction can be easily performed by removing the panel fixing bolt 6 and rotating the support leg bolt 3 from the through hole.

[0012]

As described above, according to the floor panel support leg device 8 of the present invention, even if the base portion 1 is inclined due to the uneven portion or the inclined portion of the soil 13, the support leg bolt 3 and the device can be provided. Since there is a gap between the support leg pedestals 2, the floor panel 7 itself can be kept horizontal. Further, since the supporting leg device capable of adjusting the height from above the floor panel 7 is arranged at a position where a plurality of corner portions (corner portions) of the floor panel are gathered, the corner portion of the floor panel 7 is arranged. The height can be adjusted at the same time, and the height adjustment work after installation can be easily performed, and the workability can be improved. Also,
