[Conventional technology]

Conventionally, 1 is a flooring material used in bathrooms, swimming pools, etc.
There are drainboards made of synthetic resin, but the manufacturing process is complicated and they have drawbacks in mechanical strength such as compressive strength.

Additionally, carpets, artificial turf, rubber sheets, and other carpets traditionally used outdoors on balconies, rooftops, etc. have problems with drainage, ventilation, etc., and mold, bacteria, insects, etc. can grow between the floor surface and the carpet. This has the problem of occurring.

Furthermore, we also provide multi-purpose gymnasiums, i.e., gymnasiums that are used as pool fields in the summer and used as regular gymnasiums where temporary flooring is laid on the pool in the winter for ball games, etc., flooring for temporary stages, teaching podiums, and floors for residences. Unit flooring materials with legs are becoming popular. The unit floor material is 500 s/m in length x 50 s/m in width.
0m/s+ or vertical 2000m/m x width 1000
A floor is formed by laying unit members such as thorns/■.

In recent years, the introduction of office automation equipment such as personal computers has increased dramatically, especially in offices, etc., and the use of cables, optical fibers, and communication lines for telecommunications (
(hereinafter simply referred to as communication lines) are being installed in large numbers. Currently, many of these communication lines are laid vertically and horizontally on conventional floors or carpets, which poses problems in terms of aesthetics and safety, and an access floor that improves these issues is desired. There is.

On the other hand, many of these devices require replacement, expansion, or movement of installation locations, and as a result, there is an increasing need for floor structures that allow for easy movement of communication line installation locations.

As a floor structure that meets these needs, a relatively easily removable upper floor is installed on top of a durable base floor.
There is a method of laying communication lines between the base floor and the upper floor. Utility Model No. 57-185732, No. 57-181840, No. 57
