Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a panel for forming a free access floor from which wiring and piping can be drawn out from a desired position.

[Conventional technology and its problems]

The free access floor forms a double floor by laying panels on the foundation floor with appropriate supporting members, and wiring and piping are routed in the space between the foundation floor and panels, and wiring and piping are routed through the desired panel. It can be pulled out on the floor.

Conventional free access floor panels are generally made of aluminum alloy die-cast due to their strength and weight, but die-cast products have the drawback of being expensive.

For this reason, panels for free access floors made of inexpensive metal plates such as copper plates have also been developed. However, in the conventional metal plate panel, a reinforcing metal plate that has been subjected to uneven processing by press molding is fixed by welding to the lower surface of a flat plate-shaped panel body, and as a result, two metal plates of approximately the same size are eventually used. It has the disadvantage that the plates are stuck together and the weight is as heavy as about 7 kg / sheet. If the weight is heavy, not only the operator is burdened when the panels are spread, but also the strength of the foundation floor must be increased.

[Means for solving the problem and its action]

The present invention provides a panel for a free access floor made of a metal plate that solves the above-mentioned problems, and has a structure in which a side plate portion formed by bending a square flat plate portion made of a metal plate downward to four sides. And a reinforcing member made of a molded body of a metal plate fixed to the lower surface of the flat plate portion of the panel main body, the reinforcing member having a substantially X-shaped shape extending in a diagonal direction of the panel main body. The cross-section is formed in a concave shape having bulged portions on both sides, the bulged portion is welded and fixed to the flat plate portion of the panel body, and the mounting portion of the panel support member is provided near each X-shaped tip portion. Is provided.

In this panel, the flat plate portion of the panel body is reinforced by a substantially X-shaped reinforcing member, and the peripheral portion of the panel body is reinforced by the side plate portion formed by bending the peripheral portion downward, thereby providing overall strength. It is also designed to be lightweight.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 6 show an embodiment of the present invention. This free access floor panel has a rectangular panel body 11
And a substantially X-shaped reinforcing member 21 fixed to the lower surface thereof.

The panel body 11 has side plate portions 13 formed by bending downward on four sides of a rectangular flat plate portion 12, and is formed by bending a steel plate. Holes 14 for inserting a screwdriver for height adjustment are formed in the four corners of the flat plate portion 12, and lead holes 15 for wiring or the like are formed in the central portion and in the vicinity of the middle portion of each side. 15 is covered with disc lids 16 and 17.
The disc lids 16 and 17 can be removed as shown in FIG.

Further, the reinforcing member 21 has a substantially X-shaped shape extending in a diagonal direction of the panel body 11, and has a cross section formed in a concave shape having protruding portions 22 on both sides as shown in FIG. The reinforcing member 21 is also made of a molded metal plate, and is fixed to the panel body at the protruding portion 22 by spot welding.
A mounting portion 23 of a panel support member is fixed near each X-shaped tip of the reinforcing member 21. Mounting part of this embodiment
23 is composed of a female screw with a flange. Mounting part 23
Is provided at the same position as the screwdriver insertion hole 14 of the panel body 11 (see FIG. 5). A lead-out hole 24 for wiring or the like is also formed in the center of the reinforcing member 21.

As shown in FIG. 8, the panel is supported by the panel support member and laid on the foundation floor. In Figure-8,
Reference numeral 31 is a panel of the present invention, 32 is a base floor, 33 is a base plate of a panel supporting member, 34 is a bolt receiver fixed to the base plate 33, and 35 is a bolt. That is, the panel 31 is a bolt of the panel support member.
It is fixed in place by screwing 35 into mounting 23. The height of the panel 31 can be adjusted by rotating the bolt 35 with a screwdriver inserted through the hole 14.

As shown in FIG. 9, the panel support structure is such that the panel support member mounting portion 23 is simply a tubular body with a flange.
It is also possible to insert the head of the bolt 35 there and screw the lower part of the bolt 35 and the bolt receiver 34 together.

[Effect of device]

As described above, in the panel for the free access floor according to the present invention, the panel main body and the reinforcing member are made of a metal plate, and the reinforcing member is not a member for reinforcing the entire surface of the panel main body but is formed in a substantially X shape. Since the peripheral part of the panel body that cannot be reinforced with the reinforcing member is reinforced by the side plate part formed by bending the peripheral part downward,
The strength as a whole is large and the structure can be made lightweight. It is the same size as a conventional metal plate panel and can weigh about 4 kg / sheet.
