0) It is necessary to form the pedestal (2) and the four engaging projections (300) by applying a cutting process to a lump having a height, which not only causes a rise in material cost, but also in processing. There is a problem that it takes time and the processing cost rises.

The present invention has been made in view of the above conventional circumstances, and its technical problem is to use a pedestal formed by perforating a metal plate material and a spacer interposed between the pedestal and the floor panel. By supporting the floor panel on the pedestal, the total cost can be reduced, and the floor panel is protected from the pedestal by the cushioning property of the spacer.

[Means for Solving the Problems] The technical means taken to achieve the above-mentioned technical objects are a positioning hole opened in a pedestal screwed to a support leg, and a recess provided in a lower end of a floor panel. A positioning plate 4 piece having engaging projections in a vertically back-to-back shape is made of a synthetic resin material or a rubber material, and the positioning projection plate 4 piece is inserted into the positioning hole so that the downward projection is fitted into the pedestal. The gist is that the positioning plate is placed on the upper surface, and the adjacent positioning plates are partially connected to each other via an expandable portion that can be separated.

[Operation] According to the above technical means, the downward projection is fitted into the positioning hole of the pedestal in which the positioning hole has been opened by the boring process, and the positioning plate 4 made of synthetic resin or rubber. The pieces are placed on the same pedestal, and the recesses at the lower end of the floor panel are engaged with the upward protrusions of the alignment plates to support the floor panel on the pedestal.

Since the leg (17) of the above is fitted into the alignment hole (3), the alignment plate (4) is unnecessary, but at this time, the unnecessary alignment plate (4) should cut the expansion part (7). It may be separated by.

[Effects of the Invention] The present invention has a pedestal having an alignment hole formed by drilling as described above, a downward projection that is inserted into the alignment hole, and an upward projection that engages with a recess on the back surface of the floor panel. With the alignment plate 4 pieces having a protrusion and formed of synthetic resin material or rubber material, cutting was applied to the lump to replace the conventional pedestal in which the protrusion for engaging the floor panel was formed. Therefore, the processing cost of the pedestal is low, and the four pieces of the alignment plate can be molded at low cost by using the synthetic resin material or the rubber material, and the total cost can be reduced.

In addition, the expansion and contraction of the expansion and contraction part that connects the adjacent alignment plates allows each alignment plate to move horizontally in the approaching / separating direction, so that the position of the alignment hole of the pedestal and the protrusion of the alignment plate can be adjusted. Even if an error occurs due to a hole forming error or a forming error, the error is tracked, so that the protrusion can be securely fitted into the alignment hole of the pedestal, and the hole forming process has high accuracy. Since it is not required, it can contribute to further reduction of the total cost.

Then, when the supporting legs of the border panel are directly placed on the pedestal and the alignment plate is not needed, it is sufficient to cut off the unnecessary alignment plate from the expansion / contraction part and deal with it. It is possible to easily comply with the support type of.

Furthermore, since a buffering alignment plate made of a synthetic resin material or a rubber material is interposed between the floor panel and the pedestal, the floor panel does not form an abutting relationship with the pedestal, and the floor panel is urged by the load. There is no fear of being scraped by.
