(Conventional technology) A floor panel is laid on a standard floor surface such as a concrete floor via support legs, etc., and a free space is secured between the floor panel and the standard floor surface in which cables, ventilation ducts, etc. can be placed. Double floor structures, ie raised floors, are known.

Among the above-mentioned free access 20A, for the independent type, that is, the one with a structure in which the floor panel is supported by fixed legs provided separately from the floor panel, there are multiple There is a known floor panel fixing device that supports and fixes a lower panel by engaging a panel retainer with a fixing leg.
15). According to this fixing device, as shown in FIG. 12, an adjustment table C as a support stand for supporting a floor panel B is provided on the upper part of a fixed leg A fixed to a reference floor surface, and the adjustment table C is vertically adjustable. An alignment hole is formed in the adjustment table C. Further, a flange portion F is provided at the upper end of the panel holder E, and a retaining portion G is provided at the lower end, which engages when rotated by a predetermined angle within the retaining hole. The panel retainer E is constructed by inserting the retaining part G into the retaining hole of the adjustment table C from the through hole H formed between the plurality of floor panels and rotating it by a predetermined angle, so that the engaging part G is inserted into the engaging hole. In addition, the seventh rung portion F engages with the stepped portion I of the through hole H, and the floor panel B is fixed on the adjustment table C by the panel holder E.

For a one-piece type, that is, a structure in which the floor panel is supported by support legs provided near a part of the corner of the floor panel, support consisting of a plurality of support bolts provided on the bottom surface of the floor panel is required. The legs are placed on a base fixed to a reference floor surface, and the support legs are adjusted to maintain a predetermined height from the reference floor surface (Japanese Patent Laid-Open No. 6
2-291361).

(Problem to be Solved by the Invention) However, in the above-mentioned floor panel fixing device used for independent mold manufacturing, although the panel retainer E can be easily attached with one touch, the lower end of the panel retainer E is not inserted into the engagement hole of the adjustment table C. A clearance was provided for rotatable engagement with the adjustment table C, and the adjustment table C was attached with a loose fit. Additionally, there is a drawback that it is difficult to align the ends of the plurality of floor panels to a predetermined height due to unevenness of the reference floor surface. For this reason, the panel presser E has a problem in that it is difficult to clamp the floor panel B onto the adjustment table C in a press-contact manner, and the floor panel is likely to wobble. Furthermore, the fixing device described above has a drawback that, after the floor panel is installed, in order to adjust the height of the panel retainer, the installed floor panel must be removed and operated.

In addition, in the integrated type, the support legs provided on the floor panel are easily adjusted to different heights after the floor panel is installed depending on the unevenness and slope of the reference floor surface. The disadvantage was that the legs could shift laterally, creating gaps between the floor panels.
