Abstract

PROBLEM TO BE SOLVED: To provide excellent workability by fixing multiple leg members to the back face of a panel member so that the coupling grooves of grooved panels provided on the top faces of the leg members are protruded from the corner sections and outer peripheral edges of the panel member. SOLUTION: Cylindrical leg members 3 made of a hard synthetic resin are fixed to a back face 24 at four corner sections and near the centers of the sides of a square panel member 21 made of aluminum or a hard synthetic resin. A cross-shaped or I-shaped coupling groove 32 is formed on the projection of the cylindrical top face 31 of each leg member 3. Multiple small lugs 34 are protruded on the lower end face 33 of the leg member 3, and the panel member 21 is installed on a floor slab via the small lugs 34 to construct a free-access floor. The material cost and manufacturing processes can be reduced, and the economical efficiency can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel used for a free access floor laid on the surface of a floor slab in a building, particularly a basic panel.

[0002]

2. Description of the Related Art Recently, various electric or electronic devices are used in a room such as an office provided in a building, and electric wires and communication lines used for them are provided at predetermined intervals on the surface of a floor slab. It is carried out in the free access floor that it has.

These free access floors are, for example, as shown in FIGS. 7 and 8, a square basic panel 2 having, for example, a plurality of leg members 3 installed on a slab 1 at a predetermined distance from each other, and The groove panel 5 covers the groove 4 formed between the basic panels 2 and accommodates various cables in the groove 4.

In order to form the conventional free access floor, the basic panel 2 is first attached to the floor slab 1 by a plurality of leg members 3 arranged at predetermined positions on the floor slab 1.
Install a certain distance above.

At this time, normally, the leg piece 25 bent downward along the outer peripheral edge of the base panel 2 is fitted into the cross-shaped or I-shaped fitting groove 32 formed on the top surface 31 of the leg member 3. By inserting and mounting the leg pieces 51 bent downward along the outer peripheral edge of the groove panel 5 on the top surface 31 protruding from the angle and outer peripheral edge, the basic panels 2 and 2 are placed.
The groove panel 5 is installed between them.

As described above, in the conventional free access floor, it is necessary to install a plurality of leg pieces 3 on the floor slab 1 in accordance with the arrangement position of the basic panel 2, and this work is extremely troublesome and requires skill. It was a requirement.

Therefore, a means shown in FIG. 9 is known as a means for facilitating the installation of the leg member 3.

According to this method, a plurality of leg members 3 for supporting the basic panel 2 can be easily arranged at predetermined positions, and a plurality of support frames 61 for inserting and supporting the leg members 3 have a predetermined length. A support member 6 integrally formed of, for example, a rubber material or the like is connected to each other by a connecting member 62 having a height, and the basic panel 2 can be accurately formed by simply inserting each leg member 3 into a support frame 61. Can be supported by.

[0009]

However, in the free access floor configured to support the basic panel 2 by using the conventional supporting member 6, it is necessary to insert a plurality of leg members into the supporting member 6. In addition, there is a problem that the workability is not sufficient and the supporting member 6 is required, which is not economical.

[0010]

DISCLOSURE OF THE INVENTION The present invention solves the above problems and provides a basic panel excellent in workability and economical efficiency, in which a plurality of leg members are provided on the back surface of the panel member. The fitting groove of the groove panel formed on the top surface is fixed in a state of protruding from the corner and the outer peripheral edge of the panel member.

Further, in the above-mentioned means, it is more preferable that a plurality of small projections are provided on the lower end surface of the leg member at regular intervals.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described.

FIGS. 1 to 3 show one embodiment using a basic panel according to the present invention. The basic panel 2 is a flat square panel member 21 made of, for example, aluminum, iron or hard synthetic resin. A cylindrical leg member 3 made of, for example, a hard synthetic resin and having a top surface 31 is adhered, welded, screwed or integrally combined to the back surface 24 near the center of each of the four corners 22 and each side 23. Thus, a part of the top surface 31 is provided so as to project from the corner portion 21 or the side 22.

Further, each leg member 3 fixed to the corner portion 21 has a ceiling-shaped cylindrical shape, and a cross-shaped fitting groove 32 is fixed to each side 22 on a projecting portion of the top surface 31. Each leg member 3
An I-shaped fitting groove 32 is formed on each of the protrusions on the top surface of the.

Further, the leg member 3 has four small projections 34 integrally formed on the lower end surface 33 at positions of 90 degrees from each other.

In order to construct a free access floor using a plurality of basic panels 2 of the present invention having such a structure, as shown in FIG. 4, on the surface of the floor slab 1, there is a predetermined distance from each other, that is, , A groove panel to be installed between the basic panels 2 and 2 is arranged with a distance to be installed.

As shown in FIGS. 5 and 6, the groove panel 5 is installed between the basic panels 2 and 2, and the leg pieces 52 bent downward are fitted to the respective sides 51 thereof. Good.

If necessary, the groove panel 5 may be removed and a cable such as an electric wire may be accommodated in the exposed groove 4.

In the embodiment of the present invention, the leg member 3 is fixed to each corner portion 22 and each side 23 of the panel member 21, but the leg member 3 has only four corner portions, for example. It may be fixed according to the place to install, such as sticking,
Further, it may be provided on the inner surface depending on the weight of the placed object of the panel member 2.

Further, the leg member 3 has a plurality of small projections 34 protruding from the lower end surface 33, and since it is installed on the floor slab 1 through these small projections 33, a large load is applied to these small projections 33. As compared with the conventional case where a load is applied to the entire lower end surface 33 as in the conventional case, the slip is less.

Therefore, it is not necessary to attach a rubber anti-slip material or the like to the leg member 3 as in the conventional case.

[0022]

As described above, the basic panel for a free access floor according to the present invention is excellent in workability because the leg members are integrally fixed, and the conventional supporting members are provided. In addition to the need for a separate part, it is not necessary to bend the sides of the panel member to form the leg pieces for fitting, and the material cost and the manufacturing process are small, which is extremely economical.

Further, when a plurality of small projections are provided on the lower end surface of the leg member so that the small projections have a slip preventing effect, it is not necessary to additionally provide an anti-slip material.
