Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present application relates to a floor member that constitutes a free access floor.

[0002]

2. Description of the Related Art Conventionally, as a floor member for a free access floor that is laid on a floor made of concrete and forms a wiring space such as a communication cable and a power cord with the floor, the lower surface of the floor board is A synthetic resin floor member formed by extrusion molding in which a plurality of leg pieces are suspended is known.

[0003]

However, according to the above-mentioned conventional publicly known floor member, the floor plate is formed thick and a large number of leg pieces are required due to the fact that the load resistance is required. Since three leg pieces are hung vertically on a floor board having a width, the weight of the whole is increased, which is inconvenient for transportation and handling, and the wiring space is also reduced.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned inconveniences of the conventional ones, the present application provides a floor member formed by vertically arranging a plurality of leg pieces in parallel on the lower surface of the floor plate. , A reinforcing plate is laminated, preferably, the inner surface of the root of the opposing leg is formed in a curved shape, and both sides of the reinforcing plate laminated on the lower surface of the floor plate between the opposing leg. Is curved, and the curved portion is fitted to the curved portion formed at the base portion of the leg piece, and a locking step portion is provided at the lower end of the curved portion on the inner surface of the root portion. , The lower edge of the curved portion of the reinforcing plate is locked, or both sides of the reinforcing plate are extended to the lower end portion along the inner surface of the facing leg piece, and the lower edge of the extended portion is locked to the lower end of the leg piece. It is made up of. The reinforcing plate is made of steel, and a plurality of reinforcing ridges extending in the left-right direction are juxtaposed on the flat surface thereof. Further, as a concrete configuration of the present application, the floor member has a vertical width of 5 and a horizontal width of 5 respectively.
This slit is formed by vertically arranging leg pieces on the lower surface of both sides in the lateral width direction of 00 mm and 166 mm, and slits reaching the floor board from the lower surface of the leg piece at equal positions in the longitudinal width direction. A notched portion that opens at the lower surface is formed in the leg piece portion that is evenly divided by, and a reinforcing plate is laminated at each position that is evenly divided by the slit.

[0005]

The floor member is laid on the floorboard made of concrete as in the conventional case. In this laying, when the floor member is formed by vertically arranging the leg pieces on the lower surface of both sides in the lateral width direction of the floor plate having the vertical width and the horizontal width of 500 mm and 166 mm, respectively, the floor member is connected in the lateral width direction. 3 in parallel as a unit floor member, and by laying the floor members of this unit on the floor so that the consecutive installation directions differ from each other by 90 °, a free access floor is constructed, A wiring space is formed between the leg pieces.

[0006]

EXAMPLE An example of the present application will be described in detail below with reference to the drawings. The floorboard 1 has a vertical width and a horizontal width of 500 mm, respectively. It has a substantially vertical shape, the inner side surface is largely curved at the root portion, has a locking step portion 2 at its lower end, and is integrally provided with leg pieces 3 and 3 which are tapered in a tapered shape. A hollow portion 4 penetrating in the front-rear direction is provided at the roots of the leg pieces 3, 3 thus configured, and a wide grounding portion 5 is provided at the lower edge.
Is provided.

The floor member constructed as described above is produced by, for example, extrusion molding of vinyl chloride resin, and
A slit 6 that reaches from the lower surface of the leg piece 3 to the position of the floor plate 1 is provided at a position that divides the leg piece 3 in the vertical direction (front-back direction). A notch 7 having a shape is provided.

A reinforcing plate 10 laminated on the lower surface of the floor plate 1.
Is made of a steel plate having a front-rear width of approximately 150 mm, and curved portions 8 formed at the base of the leg piece 3 on the left and right sides thereof.
The curved parts 11 and 11 that match with are provided respectively,
On the plane portion 12, three U-shaped reinforcing ridges 13 extending in the left-right direction are arranged in parallel.

The reinforcing plate 10 thus constructed is overlapped with the lower surface of the floor plate 1, and the curved portions 11, 11 formed on the left and right side portions are curved on the inner surfaces of the root portions of the leg pieces 3, 3 facing each other. The reinforcing plate 10 is fitted to the lower part of the floor plate 1 and the curved parts 8 and 8 by being fitted to the part 8 and the lower edge of which is locked to the locking step part 2. Are glued.

In use, however, the floor member of the present invention is laid on a floorboard made of concrete as in the conventional case.
In this case, make sure that the floorboards 1 are connected to each other in the widthwise direction.
The individual floor members are arranged in parallel to form a unit floor member having a size of about 500 mm on one side, and the floor members of adjacent units are laid so that the connecting directions of the floor plates 1 differ from each other by 90 °. It

In FIG. 3, the left and right side portions of the reinforcing plate 10 are further extended so that the extended portions 10a are closely attached to the inner surfaces of the leg pieces 3 and 3, and the lower edges thereof are locked to the ground portion 5. 2 shows another embodiment of the present invention, and in the case of this configuration, the extension portion 10a
A notch is provided at a position facing the notch 7 and the locking step 2 is omitted.

[0012]

As described above, according to the present invention, since the mechanical strength is increased by laminating the reinforcing plates, the floor plate can be made thin, and the leg pieces are reduced to reduce the distance between them. Since it can be formed widely, the material can be reduced as a whole, and a large wiring space can be provided, which is convenient for handling and wiring work. In particular, according to the configurations of claims 2 and 3, the bending is possible. By forming the portion, the mechanical strength of the root portion of the leg piece is further increased, and according to the configuration of claim 6, by forming the slit,
It has the advantage that it can absorb unevenness.
