[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor used for wiring under a floor in an office or the like.

[0002]

Conventionally, as a double floor, a structure is used in which abutting corners of a large number of floor boards are supported by floor board supports. In this structure,
In order to get the wiring passing through the space under the floorboard into and out of the room,
It is necessary to provide cuts in some of the sides of the floorboard.

[0003] These cuts cause stress concentration and reduce the strength and rigidity of the floorboard. In particular, in the case of a floor plate using a metal plate, it is difficult to provide a reinforcing material around the cut portion, so that the rigidity is greatly reduced.

[0004] In addition, there is also known a structure in which each floor plate is directly mounted on a ground surface, a gap is provided between the floor plates, the space is covered with a lid, and a part of the lid is opened to allow wiring to enter and exit. In this structure, the sides of the floorboard are straight, so that the strength and rigidity of the floorboard are prevented from lowering. However, in this structure, since each floorboard is separately mounted on the ground surface, it is difficult to adjust the height. For this reason, the floor of the room is an imperfect plane similar to the ground plane which is not usually an accurate plane.

The present invention solves these disadvantages, makes it possible to adjust the height of the floorboard using a floorboard support, and obtains high strength and rigidity by making each side of the floorboard straight. The purpose is to realize a double floor.

[0006]

According to the present invention, one floor plate supporter supports each floor plate to be abutted together with a gap provided between the sides thereof, and the lid member supports the gap with the floor plate. It is made to cover.

Accordingly, the height of the floor plate support can be adjusted so that the butted portion can be raised and lowered. Also, by entering and exiting the wiring from the gap, notches are not required, and the sides of the floor plate can be made straight. .

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The concrete structure of the present invention is that a plurality of side walls are formed in a straight line and are arranged side by side to form a floor of a room. 1 floor board support and the floor boards provided on the floor board support, which are to be abutted, are placed together while providing a gap between the sides so that wiring can enter and exit, and the height of the floor board can be adjusted so as to be adjustable. A receiving table that can raise and lower the butted corners together, a lid member that covers a gap between each side of the floor plate, and a lid receiving portion that is formed on the side of the floor plate and that detachably supports the lid member. It has a double floor.

The lid member may cover one side of the floorboard with one. However, it is convenient to provide a plurality of lid members per side, because only a part of the side can be opened. The lengths of the lid members may all be the same, or two or more different types may be used in combination. The width of the lid member, that is, the width of the gap may be all the same, or two or more different types may be used in combination. further,
In addition to the configuration in which this gap is provided between all floor plates, a configuration in which only a part of the floor plates is provided is also possible.

The lid member and the lid receiving portion may be of various configurations. For example, the lid member may be formed by forming an elongated member having a U-shaped cross section with both edge portions directed downward. The portion may extend downward from the surface of the floor panel, bend in a U-shape at the tip, and hook the lower end of the lid member.

The floor panel support may have any configuration as long as the floor panel can be placed on the floor panel as described above and the height can be adjusted. For example, a pedestal placed on a ground surface, a column that is rotatably attached to the pedestal and that stands upright, a receiving pedestal that is screwed to the column, engages with a floor plate, and becomes non-rotatable, It is possible to have a tool receiving portion formed at the upper end of the body, engaged with the tool and rotated, and capable of adjusting the height of the receiving base.
