吸収できなくなるという問題が生じる。However, in the structure of the conventional unit 2A 'with a top plate, only the four corners of the top plate 3 are connected to the legs 4.
Therefore, the parts other than the four corners, for example, the top plate center 3a and the top plate side 3b, are floating from the floor slab and have low strength. Therefore, when a load is applied to the top plate 3 from above, The amount of deflection of the plate 3 increases. In particular, when the top plate 3 is formed of a synthetic resin material, its load-bearing performance is further reduced. For example, a bogie passes many times or a large OA
When used on a floor where equipment is placed, there is a problem that the use cannot be sufficiently endured. If the number of the legs 4 is increased in order to increase the strength, a problem arises that the unevenness of the floor slab cannot be absorbed.

Are arranged in four blocks at the four corners, and the grooved unit 2B is arranged in each of five central cross-shaped blocks. As shown in FIG. 1, the main body 4A of the unit 2A with a top plate has main legs 4 hanging from four corners of a top plate 3 formed in a square shape in a plan view. The legs 4 are connected to each other. Further, a plurality of auxiliary leg portions 5 are respectively suspended from positions other than the four corners of the top plate 3 and including at least the center portion 3a of the top plate. In this embodiment, one auxiliary leg 5 is hung from the top plate center 3a, and four auxiliary legs 5 are hung from the top plate side 3b. Each auxiliary leg 5 is formed in a small column shape smaller than the main leg 4, and as shown in FIGS. 2, 5, and 6, the hanging length L 2 of each auxiliary leg 5 is the main leg 4. Droop length L 1
It is set slightly shorter than. For example, the lower end 5 a of each auxiliary leg 5 has a height difference d 1 of about 1 mm with respect to the lower end 4 a of the main leg 4, so that the auxiliary leg 5 can cope with unevenness of the floor slab 7. In addition, when a load is applied from above, the lower end 5a of the auxiliary leg 5 contacts the floor slab 7 to support the load, thereby increasing the strength of the top plate 3. Note that the number and positions of the auxiliary legs 5 are not limited to those in the embodiment of FIG. 1, as long as at least one auxiliary leg 5 is hung at least on the top plate central portion 3a. The number and position of the auxiliary legs 5 are not limited as long as they are other than the four corners of the top 3 and the center 3a of the top.

A plurality of floor panels 1 are laid side by side on the front, back, left and right, and then covered with a carpet 40. At this time, floor panel 1
A main leg 4 at four corners and a plurality of auxiliary legs 5 for reinforcing the main leg 4 are hung on the side facing the floor slab 7 of the unit 2A with a top plate constituting a part of. , and since hanging length L 2 of the auxiliary legs 5 are slightly shorter than the droop length L 1 of the main leg 4, the lower end 4a of the main leg 4 the lower end 5a of the four corners of each auxiliary leg 5 Being located slightly above, each of the auxiliary leg portions 5 is adapted to the unevenness of the floor slab 7 and can sufficiently cope with the unevenness of the floor slab 7.
In addition, when a load is applied from above the top 3, the lower end 5 a of each auxiliary leg 5 is in contact with the floor slab 7 so that the center 3 a and the side 3 b of the top are supported by the auxiliary leg 5. Thus, the strength of the entire top plate 3 is increased, and the structure that can absorb the unevenness of the floor slab 7 and at the same time can sufficiently bear the load is obtained. Moreover, since the auxiliary leg portions 5 are connected to each other by the auxiliary ribs 8, the strength of the auxiliary leg portions 5 itself can be improved, and the load bearing performance can be further improved. Since the center 8a 1 of the lower end of the auxiliary rib 8 is located above the lower end 5a of the auxiliary leg 5, the auxiliary rib 8 reinforces the auxiliary leg 5 and at the same time sufficiently copes with unevenness of the floor slab 7. You can do it.

Compared to the conventional flooring having only four legs at the four corners, the one provided with the auxiliary legs 5 and the auxiliary ribs 8 as in the present embodiment can withstand approximately twice the load, and furthermore, can apply a load. It can be seen that the amount of flexure when the slab is greatly reduced compared to the conventional case, and that the load-bearing performance is greatly improved even though the floor panel 1 is formed of a synthetic resin material. It has been found that even when used on a floor where a large OA device is placed, it can be sufficiently used.

のである。Further, since the top plate unit 2A is connected to the grooved unit 2B via the thin portion 6, the wiring is passed through the wiring groove 9 of the grooved unit 2B, so that the top plate unit 2A is formed. The space on the side facing the floor slab 7 of 2A does not need to be a wiring space. Therefore, although the floor panel 1 has a floor wiring function, the auxiliary legs 5 and the auxiliary ribs 8 can respectively hang down on the lower surface side of the top plate 3. Moreover, since the grooved unit 2B has legs 10 on both sides of the wiring groove 9, and the legs 10, 10 are connected to each other by the lower bottom plate 12, the grooved unit 2B is formed. The strength of 2B is high, and the load-bearing performance of the entire floor panel 1 can be improved.

めることが可能となる。In the case where the floor panel 1 is integrally formed of synthetic resin, it is difficult to pull out the small supporting column 5 from the mold if the supporting column 5 is suspended. A holding pin receiving portion 13 is provided near the auxiliary leg portion 5 in the plate side portion 3b, and the holding pin receiving portion 13 is pressed by a pressing pin provided in a mold, whereby the small pillar-shaped auxiliary leg portion 5 is molded. As a result, the floor panel 1 as a molded product can be easily separated from the mold. In addition, since the lower surface 13a of the holding pin receiving portion 13 is located above the lower end 5a of the auxiliary leg 5, this holding pin receiving portion 13 is also sufficient for unevenness of the floor slab 7 like the auxiliary rib 8. In addition to being able to cope with the problem, the protrusion of the holding pin receiving portion 13 eliminates the need for increasing the amount of protrusion of the holding pin. In addition, since the holding pin receiving portions 13 are provided on both sides near the auxiliary leg portion 5, the auxiliary pin receiving portion 13 is provided. The leg 5 can be reinforced by the holding pin receiving portion 13, and the strength of the auxiliary leg 5 can be further increased.
