BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view showing a state before fixing the legs of the free access floor by the fixing device of the present invention, FIG. 2 is a side view showing a state where the cutouts of the leg fitting members are fitted to the legs, and FIG. FIG. 4 is a side view of a state in which the leg is pressed down by the leg pressing member from the state and fixed to the base floor by the anchor bolt, and FIG. 4 is a perspective view of another example of the leg fitting member.

In FIG. 1, reference numeral 1 denotes a leg fitting member. Here, two cuts for forming a support plate 1a having an appropriate width are provided in parallel at the center of a rectangular metal plate, and both sides of the cuts are erected. The upper steps 1b, 1b are bent outward to form notches 1c, 1c for inserting the legs A of the free access floor F into the upper steps 1b, 1b, respectively, and the lower step 1d is provided with anchors. It is provided with a bolt hole 1e. The upper and lower tiers 1b and 1d form a stepped portion. The metal plate may have a planar shape other than a rectangular shape. In short, the above-mentioned support plate 1a, upper step 1b, notch 1c, lower step 1d, bolt hole
Anything that can form 1e is sufficient.

In FIG. 1, reference numeral 2 denotes a leg holding member, which is a foot 2a.
And a horizontal T-shaped leg holding member composed of a horizontal plate portion 2b. The foot portion 2a has a width approximately equal to the width of the support plate 1a of the leg fitting member 1, and the horizontal plate portion 2b has inner edges on both sides of the upper step portion 1b. , 1b is formed so as to be pressed against the end of the notch 1c, and the tip of the foot 2a is pressed against the leg A by the horizontal plate 2b. An anchor-bolt hole 2c corresponding to the center anchor-bolt hole 1e provided in the lower portion 1d is provided.
