[0002]

2. Description of the Related Art Double floors (free access floors) have become widespread due to office automation. The double floor is provided by lifting the finished floor panel from the floor base with the support legs.The support legs have a height adjustment function and the type that lifts the finish floor panel relatively high and the support legs have a height adjustment function. A simple type is known in which the finished floor panel is lifted up relatively low without providing any, and the present invention belongs to the latter.

As a simple type double floor structure, conventionally, as shown in FIG. 10, support legs 6 are provided at four corners of a top plate to which a carpet tile-shaped floor finishing material 67 is adhered and integrated.
It is known that a plurality of base floor materials 61 having No. 3 are arranged side by side on the floor base 11. A double floor can be constructed by simply arranging them side by side on the floor base 11. However, each base floor material 61 moves up and down individually by the impact of walking or the like, and the joints 6 of the finishing floor material are provided.
7a is easily rubbed and damaged, resulting in poor appearance. Particularly, when a carpet tile is used as the finishing floor material 67, fluffing and dirt of fibers are apt to occur.

In general, the floor base 11 is not flat or horizontal and is uneven, but it is difficult to deal with this in the double-shun structure shown in FIG. 10, and a space is provided between the adjacent floor base materials 61, 61. There was also the problem of easy occurrence.
