Thus, the present invention relates to a pedestal device for a floor panel strut that is attached to the upper end of the strut so that the floor panel can be adjusted horizontally and the level in the height direction with other strut can be adjusted even with the slanted strut.

[Conventional technology]

In business establishments and offices handling various electric or electronic devices, a large number of power supplies for those devices are required. Further, in a department handling a computer, it is necessary to provide a cable for connecting various terminal devices for input / output and the computer. Conventionally, an outlet for power supply is provided on the wall, etc., but it is possible to accidentally pull out the connection cord with your feet while walking, if you pull the connection cord from there to the place where the equipment is installed. There is a risk that it will become the underlay of other equipment or that the connection cord will be disconnected when passing a trolley or the like. In the case of computers, this can corrupt the data being input or output. Therefore, in such a department, a system is adopted in which the floor has a double structure, a connection cord is arranged between them, and an outlet or a cable connector is exposed on the floor near the installed equipment.

Such a double structure floor has a side of 30 to 60 cm and a thickness of 20
Prepare multiple -50 mm quadrilateral floor panels, set up multiple stanchions on the floor slab at intervals that correspond to the length of one side of the floor panel, and adjoin by a pedestal provided at the tip of the stanchion. It supports the corners of four floor panels.
The lower end of the column is usually fixed to a rectangular base plate,
The base plate is fixed on the floor slab with adhesive or bolts.

If the surface of the floor slab on which the pillars are erected is not flat, the height of each pillar is different and the floor panel cannot be laid flat.
Therefore, it has been conventionally performed to attach the pedestal to the column so as to be vertically movable and adjust the position of the pedestal to adjust the height of the column. However, if the base plate of the pillar is applied to the uneven part of the floor slab, the pillar itself will be erected upright, and the back surface of the corner of the floor panel cannot make surface contact with the upper surface of the pedestal, resulting in unstable support. Will be.

[Problems to be Solved by the Invention]

In order to eliminate such unstable support, the uneven part is ground to make it flat, or the thickness of the adhesive for fixing the base plate to the floor slab is adjusted, and the adhesive is used as a cushion to make it horizontal. It is done to show the degree. The work of cutting off uneven areas becomes a large-scale work, and the thickness of the adhesive may change due to time changes such as drying.Therefore, even if the adhesive is flat during construction, the floor panel may tilt over a long period of time. There is. Furthermore, it is also practiced to bite the liner between the back surface of the corner of the floor panel and the top surface of the pedestal. May occur. Therefore, the most widely practiced method at present is to insert the bolts into the four corners of the base plate and adjust the lengths of the lower ends of these bolts protruding from the base plate so that the base plate has a levelness. However, it is troublesome to do it while adjusting the four bolts.

Therefore, an object of the present invention is to provide a pedestal device for a column for a floor panel, which is capable of easily adjusting the inclination of the floor panel due to the uneven portion of the floor slab by performing level adjustment not only in the vertical direction but also in the horizontal direction. It is to be.
