(Problems to be Solved by the Invention) However, the above-mentioned conventional floor structure has problems in various aspects including ease of installation, adaptability, and the like. In other words, in the above-mentioned conventional example, in which the floor base is laid on the foundation floor surface while the inset blocks are connected to each other, there is a gap between each side (four sides) of the floor base and the adjacent floor base. Therefore, the installation work, including the work of fitting the blocks into each other, requires a lot of labor and time, resulting in poor workability. Furthermore, in the structure in which the blocks are fitted into each other,
If the interlocking of the blocks is made harder in order to firmly integrate and connect the floor bases together, the installation process will take more time and workability will become worse, and the compatibility with the foundation floor surface will also deteriorate. If the blocks are loosely fitted into each other, the installation work becomes easier, but the floor bases cannot be firmly connected to each other and the stability, flatness, etc. of the upper floor surface is impaired. occurs. In addition, in a structure in which the upper unit is placed and fixed on the lower unit via a plurality of supports, the lower unit is lined up on the foundation floor, and the upper unit is placed and fixed from above. Although the installation of the lower units is relatively easy, since the lower units are not connected to each other and are not integrated, a problem arises in that the stability, flatness, etc. of the upper floor surface is impaired.

Furthermore, in the above-mentioned conventional configuration, equal consideration is not given to cable protection measures including water leakage measures, which are the biggest problem in practical terms.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide a system floor that has good workability and adaptability, and can maintain a stable installation state without causing positional shift.
