[Industrial applications]

 The present invention is a double floor for supporting a double floor panel which is used for maintaining a work environment by storing various wiring cords under the floor in a room handling OA equipment such as a computer room and an office. It is related to the support leg for.

[0002]

[Prior art]

 Conventionally used double-floor support legs are pedestal types in which one support leg with a pedestal is installed at the junction of four double-floor panels, and each floor panel is placed on a pedestal plate. And four-column type as shown in FIG. 7 are known, and they are used according to their respective purposes.

In the conventional four-pillar support leg shown in FIG. 7, column bolts 31 are provided so as to project at four corners of the substrate 1, and a panel support 30 is screwed to each column bolt 31. (In the figure, the state where one panel support body is removed is shown.) The panel support body 30 has a cylindrical cap 32 in the upper part, a pedestal plate 34 having an annular shape in the middle, and a hexagon nut in the lower part. The cylindrical cap 32 has a screw hole 35 at its top, and a screwdriver fitting hole 33 is formed at the top of the cylindrical cap 32 so as to penetrate the top. One of these four-post type support legs is installed at the junction of four double-floor panels (hereinafter sometimes simply referred to as "floor panels"), and each floor panel has four corners on the back of the panel. The cylindrical cap 32 is fitted into the through hole formed at the location, the height is adjusted, and then fixed.

The height adjustment of the panel support 30 is performed by inserting and fitting a jig such as a screwdriver into the screwdriver fitting hole 33 and turning the jig. However, the cylindrical cap 32 is usually formed by deep-drawing a thin iron plate, and is generally fixed by simply fitting the base plate 34 and the hexagonal nut portion 35. Therefore, if the cylindrical cap 32 is forcibly rotated when the panel support 30 is in a loaded state, the cylindrical cap 32 and the hexagon nut portion 35 slide at the fitting portion, and the hexagon nut portion 35 rotates. It may not be possible to adjust the height because it is not. In this case, the height of the panel support 30 is usually adjusted by removing the adjacent floor panel and directly turning the hexagon nut portion 35 from below the floor panel using a spanner or the like.

Further, it is not easy to process the cylindrical cap 32 to a certain extent or more due to the above-mentioned manufacturing problems, and in general, the length of the cylindrical portion fitted with the floor panel is It will be shorter than the thickness of the floor panel. In this case, since the top of the cylindrical cap 32 is lower than the floor surface of the floor panel, there is a problem that a recess is seen in this portion.

Further, when the panel support 30 is fixed after the height adjustment, it is performed by injecting an adhesive from the screwing fitting hole 33 and leaving it for a predetermined time to cure the adhesive. Usually, this curing time takes about 1 hour, and the next work is generally performed after waiting for this curing, which is extremely inefficient.

On the other hand, in order to readjust the floor height after fixing once, it is necessary to dissolve the adhesive with a dissolving agent or the like, and after at least one of the adjacent floor panels is peeled off, this portion is removed. It was done by inserting a spanner or the like into the hex nut portion 35 and turning it. Therefore, the readjustment of the height was an extremely complicated and time-consuming operation. In addition, since the screw for screwing the support bolt and the panel support has some play, some rattling is inevitable.
