The strength with respect to weight varies from place to place, resulting in a soft floor overall. As a result, when walking on the floor panel or deploying OA equipment etc.,
This causes problems such as instability.

Further, in the above-mentioned conventional floor panel, squeaking between the floor material and the cover member is likely to occur, which may cause unpleasant noise due to squeaking and curved deformation of the cover member. As a result, there arises a problem that the cover member is exhausted due to bending deformation and the like.

The present invention has been made in view of the above problems, and an object thereof is to increase strength against weight and prevent fatigue of members due to bending deformation and the like. To provide.

[0006]

In order to achieve the above-mentioned object, the present invention has standing portions standing upright at predetermined intervals and forming grooves between the mounting surfaces of each standing portion. In a floor panel including a floor material and a cover member placed on the placement surface of the standing portion so as to cover substantially the entire surface of the floor material, in the cover member, corresponding to the groove portion. The gist of the present invention is that the thickness of the formed portion is made thicker than the portion corresponding to the mounting surface of the standing portion, and the fitting portion that fits into the groove portion is provided by the thick portion.

[0007]

According to the above structure, the cover member placed on the placement surface of the standing portion covers substantially the entire floor material, and the entire floor material is in a uniform state. Further, in this state, since the thickness of the portion of the cover member corresponding to the groove portion is thicker than the thickness of the portion corresponding to the mounting surface of the upright portion, the portion corresponding to the groove portion is reinforced. As a result, the strength with respect to weight is maintained substantially even at any part of the surface of the floor material.

Further, since the fitting portion provided in the thick portion of the cover member fits in the groove, the lateral displacement and squeaking of the cover member are prevented, and the cover member is prevented from being curved and deformed. .
