The free access 70A is constructed by laying it on a plurality of floor panels 2 and a reference floor surface 3 such as a concrete floor via support legs 4. The support leg 4 is disposed below a position where four corner portions 2a of four mutually adjacent floor panels 2 come together in the center of the free access 70a1, and also on the wall surface of the free access 70a1. In the side portion, the corner portions 2a of the two adjacent floor panels 2 are arranged below the position where the two corner portions 2a come together.

The fixing fitting 5 is formed into a rectangular plate shape, and a fixing part 5a that engages with the presser plate 7 is provided at the tip. A projection 5f that engages with a hole 7d formed in the holding plate 7 is provided. In addition, reinforcing plates 5b are integrally formed on both side edges of a portion from near the center of the dowel to the fixing s5a at the tip.

A slit 5c extending in the length direction and into which the fixing bolt 6 is inserted is provided in the central portion, and a rack portion 5d that engages with the positioning member 8 is formed on the back surface of the slit 5c.

This fixing metal fitting 5 is inserted through the slit 5c and the insertion hole 8a of the positioning member 8, and is further inserted into the hole 2b of the floor panel 2.
The fixing bolt 6 inserted through the nut 20 is screwed and tightened to be tightly fixed. The fixing fittings 5 are arranged as shown in FIG. At this time, the rack portion 5d and the rack portion 8b of the positioning member 8 are engaged with each other, thereby preventing the fixing member 5 from moving in the horizontal direction along the slit 5c.

The holding plate 7 has a horizontal portion 7a and a vertical portion 7b, which have a cross-sectional shape, and the horizontal portion 7a is provided with a leg receiving portion 7c and a hole 7d formed in a 0-shape, while the vertical portion 7b is provided with a screw hole 7e into which the bolt 12 is screwed. Furthermore, one or more liners 9 are appropriately attached to the lower surface of the horizontal portion 7a by welding or gluing so as to match the height of the leg base portion 11b of the leg portion 11. This holding plate 7 is engaged with the leg portion 11 of the device 10, and the protrusion 5f of the fixing metal fitting 5 is inserted into the hole 7d, so that when the fixing metal fitting 5 is fixed, the leg base portion 11b is pressed. It is fixed at Furthermore, since the fixing metal fitting 5 and the holding plate 7 are always maintained in a state of contact by the pressure bonding between the tip of the bolt 12 screwed into the screw hole 7e and the upper surface of the fixing part 5a, the fixing metal fitting 5 is prevented from floating up. Even if there is, the protrusion 5f is prevented from coming out of the hole 7d.

A floor panel 2 on a raised floor 1 on which equipment 10 such as a computer is installed is formed with a hole 2b at a predetermined position through which a fixing bolt 6 is inserted, and a nut 20 is press-fitted into the hole 2d. The holes 2b are provided in a plurality of mounting portions 2c formed at the intersections of reinforcing ribs (not shown) on the back surface of the 70 Avanel 2. Therefore, the load applied to the hole 2b via the holding plate 7 and the fixing metal fittings 5 due to movement of the equipment 10 due to earthquakes, vibrations, etc. is distributed to the reinforcing ribs, and deformation or damage to the floor panel 2 is prevented. .

Now, to fix the device 10 such as a computer, the leg holder 7c of the holding plate 7 is engaged with the leg 11 of the device IO placed on the floor panel 2, and then the column base of the fixing bracket 5 is inserted. This is done by engaging the portion 5e with the column base 11a, inserting the protrusion 5f into the hole 7d of the holding plate 7, and fixing the fixture 5 with the fixing bolt 6. Therefore, the horizontal movement of the device 10 is prevented by the column base insertion part 5e and the leg receiving part 7c sandwiching the column base 11a, and on the other hand, the holding plate 7 fixed to the fixture 5 is prevented from lifting up. This is prevented by pressing the base portion 11b from above.

When changing the device, it is only necessary to replace the presser plate 7 with one having a liner 9 attached to the lower surface corresponding to the height of the footrest 11b, and this operation can be easily performed.

Further, an insulator 14 is provided between the fixing bolt 6 and the fixing metal fitting 5, and this insulator 14 covers the outer peripheral surface of the shaft portion 6a of the fixing bolt 6 and the lower surface of the washer 13 attached to the fixing bolt 6. is formed. An insulator 2d such as a melamine board is laid on the upper surface of the floor panel 2. Such a structure maintains the electrical insulation between the fixture 5 (equipment 10) and the floor panel 2.

5 and 6 show another embodiment of the present invention, in which a device 21 having casters 15 is fixed on a floor panel 2. FIG.

That is, the connecting member 16 is sandwiched between the bottom of the device 21 and the mounting plate 15a of the caster 15, and the holding plate 17 is fixed to the holding plate 17 by welding. A protrusion 5f and a hole 17a are provided on the fixed part 5a.
are attached so that they engage with each other. Then, the device 21 is securely fixed by tightening the bolt 18 inserted through the insertion hole 16a of the connecting member 16 and the nut 19.
