Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial Application Field) The present invention relates to a system floor used when performing underfloor shielding wiring of power cables, signal cables, etc. of various devices for realizing office automation. About.

(Prior Art) Conventionally, as a system floor used when performing underfloor shielding wiring of power cables, signal cables, and the like of various devices for realizing office automation, for example, Japanese Unexamined Utility Model Publication No. 61-76045 is disclosed. As described above, a fitting block having a specific shape meshing with each other is integrally provided on a peripheral portion of a rectangular base (floor base) laid on the foundation floor, and the fitting blocks are connected to each other to form a rectangular shape. A structure in which a base (floor base) is laid on the base floor surface, or as shown in JP-A-60-40472, a plurality of columns are provided in a lower unit, and an upper portion is provided by the columns. There is a configuration in which an upper unit is placed and fixed on a lower unit via a unit and laid on a foundation floor surface.

(Problems to be Solved by the Invention) However, the above-mentioned conventional floor structure has problems in various aspects including laying workability and adaptability. That is, in the prior art described above, in any of the configurations, the bottom of the base member called a bottom plate, a base plate, or the like has a flat plate shape, and therefore, it is not laid on the base floor surface in a surface contact state. Stickiness occurs, and the conformability to the foundation floor surface is impaired. At this time, in order to lay the base member on the same plane in a stable state, high flatness is required for the surface finish of the foundation floor surface, and therefore, in various aspects such as construction cost, construction period, workability, etc. Problems arise.

Further, in the above-described configuration in which the floor base is laid on the foundation floor surface while the fitting blocks are connected to each other, each side (four sides) of the floor base is connected to the adjacent floor base. There is a problem that the work of inserting the blocks into each other is required, so that the laying work including the work of inserting the blocks into each other requires much labor and time, and the workability is poor. Furthermore, in the above-described block-fitting structure, if the blocks-fitting are hardened so that the floor bases are firmly integrated with each other, more time is required for the laying work, and the workability becomes worse. There is a problem that the familiarity (fitness) with the base floor surface also deteriorates. If the blocks are loosely fitted, the laying work becomes easy, but the floor bases cannot be firmly integrated with each other. However, there arises a problem that the stability, flatness and the like are deteriorated. Also, in the structure in which the upper unit is placed and fixed on the lower unit via a plurality of columns, the lower unit is arranged on the base floor, and the upper unit is placed and fixed from above, Although the lower units are relatively easy to lay, the lower units are not connected to each other and are not integrated, which causes a problem that the stability and flatness of the upper floor surface are impaired.

Therefore, as shown in Japanese Patent Application No. 1-242835, columns at the same height are provided at each intersection of the lattice frame to support the floor panel at multiple points, making it easy to fit into the basic floor surface. A floor base of a system floor that can be laid and constructed by simple work was considered.

However, the floor base having such a configuration has a structure in which a large number of pillars are integrally provided on a lattice-shaped frame, so that the structure becomes complicated, and there remains a problem in terms of cost and handling. I was
