Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-floor panel which is laid on a structural floor of a building to form a double-floor, and electric wires, optical fiber communication cables and the like are appropriately wired under the floor.

[0002]

2. Description of the Related Art In order to mechanize an office or the like, the floor of the office or the like is doubled, and wires for office equipment, optical fiber communication cables, etc. are laid under the floor.
A double-floor panel is known in which a large number of flat plate panels with legs are arranged side by side on a structural floor (for a similar technique, see the publication of Utility Model Registration No. 3053391).

This type of floor-standing double-floor panel is designed to withstand the weight of a desk or bookcase placed on a flat panel even if the weight is concentrated on a small number of legs. Prevents the gap between them and prevents the joints from bending even when the two floor panels connected to each other are lifted up. A floor panel top plate portion integrally formed with ribs and a column for inserting a pedestal, and a plurality of short pedestals to be inserted into the tubular body on the lower surface of the top plate portion are perpendicular to the top plate portion and Standing parallel to each other, connecting ribs extending vertically and horizontally diagonally between the pedestals are composed of the pedestal part integrally molded with the pedestal, and the pedestal part and the top plate part are mutually connected. The pedestal part and the top plate are Not only it does not shift, but not causing irregular asperity to the floor surface.

[0004]

However, in such a conventional technique, the pedestal portion of the pedestal portion is immersed in the cylindrical body formed on the lower surface of the top plate portion, so that the pedestal portion is formed. Since the top plate is supported on the pedestal, the diameter of the cylindrical body must be molded to a size that takes into account the dimensional tolerance between the multiple pedestals of the pedestal, which is a so-called stupid hole. The relationship, that is, the diameter of the cylinder is too large for the diameter of the pedestal, and the gap between the peripheral surface of the pedestal and the peripheral surface of the cylinder of the pedestal part The top plate may move in a substantially horizontal direction on the pedestal.

The present invention has been made by paying attention to such a conventional technique, and has a structure in which a pedestal of a pedestal portion and a support portion of a top plate portion are easily fitted to each other even if a dimensional error occurs. By doing so, it is possible to provide a laid-down double floor panel in which the top plate portion is hard to move in a substantially horizontal direction with respect to the pedestal portion.

[0006]

According to a first aspect of the present invention, there is provided a substantially square top plate part having an upper surface formed in a substantially flat surface and a lattice rib-shaped reinforcing part formed on a lower surface thereof. A laying ground consisting of a thin-walled base portion formed in substantially the same shape as the top plate portion and placed on the structural floor of the building, and a pedestal portion having pedestals that are erected at predetermined intervals on the base portion. It is a heavy floor panel, and an engaging support part is formed on the top part of the pedestal part so that a part of the reinforcing part of the top plate part can be fitted as a supporting part, and the engaging support part is to name a cross-shaped,
Around the portion that will be the support portion of the reinforcement portion of the top plate,
The intersecting portion is formed and is surrounded by the base portion.

In addition to having a protrusion amount from the outermost side to the inner side between the pillars,
The second support part is formed so as to be engageable with the first support part.
Characterized in that it comprises.

According to the first aspect of the present invention, the reinforcing portion formed on the lower surface of the top plate portion is formed in a grid rib shape and is formed on the pedestal of the pedestal portion. Since the engagement support portion is formed in a cross shape, at least two of the four sides are fitted in the horizontal direction, and a dimensional error occurs between the reinforcement portion and the engagement support portion. However, not only the fitting is easy, but also the movement in the substantially horizontal direction is prevented. In other words, the manufacturing cost can be reduced because the precision of the double floor panel is not so high as in the conventional case, and the top plate portion does not move in the horizontal direction, so that the stability is increased. Since the base portion is thin, it is possible to follow even if the structural floor is uneven. Also, the reinforcing portion
