Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a double-floor panel that is laid on the structural floor of a building, and is used as a double-floor, and wires and optical fiber communication cables are appropriately routed under the floor. Regarding what was done.

[0002]

[Prior art]

 In order to mechanize the office (office automation), the office floor is doubled, and wires and optical fiber communication cables for office equipment are laid under the floor. For this purpose, many flat panels with legs are laid side by side on the structural floor, and carpets etc. are laid on top of them. As a flat panel, a light metal cast panel with the legs integrally molded was used initially, but in recent years, a reinforced plastic integral molded product with a similar shape has been used.

[0003]

[Problems to be solved by the invention]

 In offices, desks, bookcases, and other heavy objects are placed as appropriate, and the weight is concentrated on a small number of legs. Therefore, the floor must have a structure that can withstand such stress concentration. Also, it is desirable that the double floor panel, once placed on the floor, be securely fixed so that there is no gap or gap between adjacent floor panels. In addition, even after the office has begun to be used, it is necessary to change the initial underfloor wiring appropriately as layout changes, office equipment are replaced or expanded. In such a case, the required number of double floor panels on the floor are moved to replace or install new wiring. Therefore, the floor panels must be quickly moved or removed as necessary, and the wiring under them must be replaced or newly installed.

In a double floor panel, in order to prevent a gap between adjacent floor panels, a band-shaped upper joint is conventionally provided from a suitable upper edge of a flat plate of a panel to an upper edge of a flat plate of an adjacent panel. Passing over was common. This is effective in preventing the floor panel from shifting, but when the connected floor panel is lifted, the upper joint may be bent upward and the joint may be damaged. Therefore, as described later, the inventor of the present invention provided a joint portion extending obliquely upward or downward toward the adjacent leg at the tip of the leg portion suspended from the flat plate, and By arranging the slopes in such a manner that the slopes are arranged obliquely upward and then obliquely downward, the connecting portion is not bent even when two connected floor panels are lifted. Although some improvements have been made to the connection of floor panels in this way, the inconvenience of having to lift the floor panels together with the legs when installing or replacing floor wiring has changed. There was no.

[0005]

[Means for Solving the Problems]

 According to the present invention, the above object is achieved by a floor panel top plate portion integrally formed on a back surface of a rectangular plate with a plurality of reinforcing ribs extending in a direction perpendicular to the rectangular plate and a pillar insertion cylinder. A plurality of short pillars to be inserted into the cylinder on the back of the plate are erected so as to be parallel to each other, and connecting ribs extending vertically, horizontally and diagonally between the pillars are formed integrally with the pillars. This is achieved by a low-floor double-floor panel consisting of a pedestal portion and a floor. As for the connection between the top panel and the top panel, a pair of male and female connecting sections for connecting to the adjoining floor panel and column of the same shape are provided on the top panel and the pillar, respectively. ing. With the above configuration, the floor panels can be continuously arranged in the vertical and horizontal directions of the floor surface, and the floor panels do not shift from adjacent panels.

In another embodiment of the present invention, a connecting rib of the pillar is pivotally attached to the pillar, and the rib pivots in a pantograph manner with respect to the pillar, and the rib is pivoted relative to the pillar. The whole can be expanded and contracted in the horizontal direction. With this configuration, the pillar can be used not only for a rectangular top plate but also for an elongated top plate by adjusting the distance between the pillars.

[0007] The double floor panel of the present invention can be made lightweight and inexpensive by integrally molding the top plate and / or the pillars with a flame-retardant reinforced plastic resin such as phenol resin, melamine resin, silicon resin and the like. A heavy floor panel is obtained. These reinforced plastics can be reinforced by injecting glass fibers, especially in areas where stress is concentrated. If necessary, a conductive substance can be added to the plastic material to prevent static electricity.

[0008]

[Action]

 Since the present invention is constructed as described above, first, the required number of pillars are laid on the floor slab of a building or the like while being connected to each other in four directions on the left and right. In this case, the gap between the pillars is arranged so as to coincide with the gap of the pillar insertion cylinder provided on the lower surface of the top panel of the floor panel in at least one direction. Wire electric wires, optical fiber communication cables, etc., including their terminal connections between the pillars, and then, while displaying or exposing the positions of the terminal connections on the top panel, attach the top plate to its legs. The pillar insertion cylinder is inserted into the already-installed pillar, and is fixedly arranged on the pillar while interconnecting with the adjacent top plate.

[0009] Since the wiring is performed before the arrangement of the top plate portion, the layout is easier than the conventional wiring method of inserting between the pillars of the top plate, and the number of the wirings is increased or decreased. Also, when making changes, the work can be done easily and reliably compared to the conventional method, since the work can be done by peeling off only the top plate while leaving the pillars intact. When fixedly mounted on the pillars, the legs and / or the top plate may be connected to each other, even if a heavy object is placed on the floor or moved. There will be no lateral displacement of the pillars or top plate, or irregular irregularities on the floor.
