Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a double floor.

[0002]

2. Description of the Related Art Double floors are often used when arranging power supplies for information processing devices such as computers or data cables in the underfloor space. Conventionally, the one shown in FIG. 6 has been proposed. ing. In this conventional example, on the floor slab 1,
A panel support device 4 including a box-shaped support portion 9 and panel support legs 2 is installed, and a plurality of floor panels 5, 5, ... Are installed with the four corners supported by the panel support legs 2.

Further, in order to prevent a leakage of electric current in the case of inundation or the like, a cable or the like arranged in a space below the floor constituted by the floor panel 5 is held at an appropriate height above the floor slab 1. A square cable separator 10 having a plan view shape substantially the same as that of the floor panel 5 is installed on the support portion 9.

[0004]

However, in the above-mentioned conventional example, the cable separator 10 is formed to have substantially the same size as the floor panel 5, and the four corners thereof are engaged with the support portion 9. The cable separator 10
When inspecting equipment installed below the cable, the situation cannot be seen because the cable separator 10 interferes, and also when cleaning the floor slab 1 in the event of water leaks, etc. Since the separator 10 alone cannot be removed, the maintenance is troublesome.

The present invention has been made to solve the above drawbacks, and an object thereof is to provide a double floor which is easy to maintain.

[0006]

According to the present invention, the above object is achieved by connecting a panel supporting leg 2 standing on a floor slab 1 with a connecting beam 3 as shown in FIGS. A panel support device 4 formed by connecting in a grid pattern, a plurality of floor panels 5, 5, ... Supported by the panel support device 4, and locking portions 6 formed at both ends thereof are connected to the connecting beam 3 A cable holding portion 7 that is detachably locked to the connection beam 3 and is installed between the connecting beams 3, and that holds wiring under the floor panel 5 at a predetermined height above the floor slab 1 by a cable holding portion 7 formed in the middle portion. This is achieved by providing a double floor comprising cable rails 8.

[0007]

In the present invention, the panel supporting device 4 is constituted by connecting the panel supporting legs 2 standing on the floor slab 1 by the connecting beams 3 in a grid pattern, and the cable rails 8 are provided between the connecting beams 3. Is detachably installed. The connecting beam 3 is formed in a rod shape, and even in the installed state,
It is possible to check the state of the equipment below, and moreover, by simply removing the corresponding floor panel 5, a space for removing the connecting beam 3 is secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. An embodiment in which the present invention is applied to a seismic isolated floor is shown in FIGS. 1 and 2. The seismic isolation floor includes a panel support device 4 slidable on the floor slab 1, and a plurality of floor panels 5, 5, ... Supported by the panel support device 4.
And a cable rail 8 installed between the connecting beams 3 of the panel support device 4, and when an earthquake occurs, the floor panel 5 surface moves relative to the floor slab 1 and is installed on the floor panel 5 surface. Is configured to absorb shocks to the equipment being used.

The panel support device 4, as shown in FIG.
A slide plate 11 slidably supported on a slide bearing member (not shown) fixed on the floor slab 1, and a leg fixing member 12 fixed on the slide plate 11.
A panel support leg 2 whose lower end is fixed to the leg fixing member 12,
There is a connecting beam 3 for connecting the panel supporting legs 2 to each other in a grid pattern, and the panel receiving surfaces 13 fixed to the upper ends of the panel supporting legs 2 support the rear surfaces of the four corners of the floor panel 5.

In FIG. 3, 14 is a floor panel 5.
The four corners of the floor are pressed down from above and each floor panel 5
A panel presser for connecting and fixing the spaces to each other, and a cover 15 mounted on the head 14a of the panel presser 14.

As shown in detail in FIGS. 3 and 4, the connecting beam 3 is formed by bending and is formed into a U-shaped channel portion 16 and a side portion outward along the lower end of the channel portion 16. It is composed of a bent portion 17 and a bent portion 17.
The channel portion 16 has a bolt insertion hole 19 through which a bolt 18 for fixing to the slide plate 11 is inserted, and a bolt recessed around the bolt insertion hole 19 so as to accommodate the head portion 18a of the bolt 18. The slide plate has a support surface 20 and a retainer portion 21 for pressing the projecting portion 12a of the leg fixing member 12, and the both ends are fitted on the plate support portion 22 of the slide plate 11. It will be installed between 11

On the other hand, the cable rail 8 is a rod-shaped rod having an intermediate portion as a cable holding portion 7, and both ends thereof are crushed and bent into an L-shape to form a locking portion 6. Further, in order to detachably lock the locking portion 6 of the connecting beam 3, a long hole 23 is formed in the connecting beam 3.

With the above-mentioned structure, the cable A, the piping, and the like arranged below the floor panel surface are connected to the connecting beam 3.
It is held at an appropriate height on the floor slab 1 while being supported by the cable holding portion 7 of the cable rail 8.

Another embodiment of the present invention is shown in FIG. In this embodiment, the panel support device 4 comprises a panel support leg 2 fixed on the floor slab 1 and a connecting beam 3 connecting between the upper ends of the panel support leg 2. The connecting beam 3 also serves as a panel support rod that supports the back surface of the floor panel 4 around the four sides thereof, and like the above-described embodiment, the channel portion 1 is provided.
6 and the bent portion 17, the channel portion 16 and the bent portion 1
A long hole 23 for receiving the locking portion 6 of the cable rail 8 is formed at the boundary with the cable rail 7.

Further, in this embodiment in which the connecting beam 3 is arranged at the upper end of the panel supporting device 4, the cable rail 8 has a hanging portion 24 formed by bending both ends of the cable holding portion 7 upward. The upper end is provided with a locking portion 6, so that a space for inserting the cable A can be provided between the cable holding portion 7 and the back surface of the floor panel 5.

Therefore, in this embodiment, the cable A is supported by the cable holding portion 7 of the cable rail 8 and disposed at an appropriate height above the floor slab 1, and below it, that is, on the floor slab 1. The cable A can be inserted.

Further, in this embodiment, the hanging part 24
When a plurality of cable rails 8 having different heights are mounted, the cables A can be arranged in a plurality of layers in a stacked manner, so that the cable wiring can be divided according to the type and the like.

[0018]

As is apparent from the above description, according to the present invention, since the cable rail is formed in the shape of a rod, it is possible to visually check the condition of the equipment below and the space where the floor panel is removed. Since it can be easily removed from the outside, maintainability can be improved.
