[Prior art]

 The free-access floor must be laid so that its legs cannot be lifted or displaced from the base floor. The reason is that furniture such as partitions and storages are usually placed on the free access floor, so if the legs are lifted or displaced from the base floor due to an earthquake or vibration, This is because there is a risk that furniture may fall over or slip in, causing danger.

Conventionally, when the legs of the free access floor are fixed to the base floor, a fixing metal fitting having a leg insertion hole is inserted into the leg insertion hole, and an adhesive or an anchor bolt is attached to the base floor. Although it was possible to prevent the floor from slipping, it is not possible to prevent the legs from rising from the base floor in the event of an earthquake or vibration.

Therefore, as shown in FIG. 5, a notch 12 for inserting the leg A of the free access floor into the upper tier 11 is a two-tier type in which one plate is erected from an appropriate place and bent outward. As shown in FIG. 6, a leg A in which two nuts 16 are preliminarily screwed into the notch 12 of the mounting bracket formed on the mounting portion 13 to the base floor F is provided with two nuts 16, With the 16 parts inserted, the mounting portion 13 is fixed to the base floor F with an adhesive, or the mounting portion 13 is provided with anchor bolt mounting holes 14 as shown in FIG. After fixing to the base floor F with the bolt B, the upper tier 11 is clamped by the nuts 16 and 16 so as to be held between them, or as shown in FIG. Install a flange 17 that matches the height of the Then, with the space between the flange 17 and the nut 16 inserted into the notch 12 of the mounting bracket, fix the mounting part to the base floor F in the same manner as above, and tighten the nut 16 to tighten the earthquake or vibration. Even so, the legs A were not lifted or displaced from the base floor F.

According to the above-mentioned device, it is possible to prevent the legs from rising and shifting from the base floor. However, not only the work for that purpose is complicated, but also the fitting itself has an unstable shape. Therefore, there is a problem that it is easy to fall down and it is difficult to handle, and if flanges are provided on the legs, there is a risk that rattling may occur after laying the floor unless the positions where the flanges are provided are accurate.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a free access floor before fixing legs by a fixing device of the present invention, FIG. 2 is a side view of a state in which a notch of a leg fitting member is fitted into the leg, and FIG. From the state, the leg is pressed by the leg pressing member 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 notches for forming a supporting plate 1a having an appropriate width are provided in parallel at the center of a rectangular metal plate, and both sides of the notches are provided. The upper steps 1b, 1b are formed to be upright and bent outward, and notches 1c, 1c for inserting the legs A of the free access floor F are provided in the upper steps 1b, 1b, respectively. And is provided with an anchor bolt hole 1e. The upper and lower steps 1b and 1d form a stepped portion. The metal plate may have a planar shape other than the rectangular shape. The point is that it is sufficient if the support plate 1a, the upper step portion 1b, the cutout portion 1c, the lower step portion 1d and the bolt hole 1e can be formed.

In FIG. 1, reference numeral 2 denotes a leg pressing member, which is a flat T-shaped leg pressing member composed of a foot portion 2a and a lateral plate portion 2b, and the foot portion 2a is of the same degree as the supporting plate 1a of the leg fitting member 1. The lateral plate portion 2b is formed so that the inner edges of both sides of the lateral plate portion 2b can push the leg A inserted into the upper step portions 1b, 1b against the end portion of the cutout portion 1c, and the tip portion of the foot portion 2a. When the leg A is pressed down by the lateral plate portion 2b, an anchor bolt hole 2c is formed to match the central anchor bolt hole 1e provided in the lower step portion 1d of the leg fitting member 1.

The leg fixing device of the present invention comprises the leg fitting member 1 and the leg pressing member 2, and the height of the inner surface of the upper step portion 1b, 1b of the leg inserting member 1 is equal to that of the leg A. The thickness of the pedestal A1 and the thickness of the lateral plate portion 2b of the foot pressing member 2 are made to be slightly larger than the sum.

The leg A is fixed by the above device as follows. First, as shown in FIG. 2, one notch 1c of the upper step portion 1b of the leg fitting member 1 is fitted to the leg A of the floor panel arranged on the base floor F, and the adhesive is applied to the back surface of the lower step portion 1d. Apply and temporarily fix to the base floor F. Then, as shown in FIG. 3, after the leg A of the other floor panel is inserted into the other cutout portion 1c of the upper step portion 1b, the foot portion 2a of the leg pressing member 2 is attached to the lower end portion of the leg inserting member 1 at the tip portion 2a. When the anchor bolt hole 2c is aligned with the anchor bolt hole 1e on the portion 1d, the lateral plate portion 2b of the leg pressing member 2 presses the leg A against the end of the cutout portion 1c. Here, the anchor bolt B is driven and fixed to the base floor F through the anchor bolt holes 1e and 2c.

In this way, by fixing the leg fitting member supporting the leg A and the leg pressing member on the base floor F, the leg A does not float or shift even when subjected to an earthquake or vibration. Therefore, even if furniture such as partitions and storages are placed on the free access floor, there is almost no risk of them falling due to an earthquake or vibration.

In the leg fixing device of the present invention, the leg fitting member 1 may be formed as shown in FIG. That is, the notches 1f and 1f formed between the support plate 1a and the upper step portions 1b and 1b are not formed to the boundary of the stepped portion by the upper and lower step portions 1b and 1d as in the example of FIG. The lateral plate portion 2b of the retaining member 2 is formed to have a front-rear width that allows the vertical insertion. In this way, the front and rear width of the cut portion 1f facilitates the alignment of the anchor bolt holes 1e and 2c. In addition, such a shape and structure is preferable in manufacturing because molding in one step by press working becomes easier.

[0016]

The present invention is as described above, and the cooperation of the leg fitting member and the leg pressing member can surely prevent the legs of the panel forming the free access floor from being lifted and displaced. .

Since the leg fitting member is integrally provided with the support plate at the lower step thereof, when the notch is fitted into the leg and placed on the base floor, the stability is high and there is no risk of tipping over. Is extremely easy and the workability is good, and in the case of temporarily fixing it on the base floor with an adhesive, the conventional work could not move to the next work until the adhesive solidified. Since the work can be immediately started after the temporary fixing, the work for laying the free access floor can be easily and efficiently performed.
