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 (hereinafter, referred to as a floor base) laid on the foundation floor, and the fitting blocks are connected to each other. A structure in which a rectangular floor base is laid on a foundation 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.

As described above, when assembling a partition when constructing an office automation system in an office on the system floor, the lower end of the partition is fixed to the floor panel by bolts. In addition, in order to partition the floor, a pole on the floor, that is, a plurality of columns are erected, and when these columns are covered with a partition panel, the lower end of the column is generally fixed to the floor panel with bolts or the like, The upper end is fixed to the ceiling panel with bolts. Also,
To cope with such an option, there is a construction in which a through hole is provided in the floor panel in advance, and a pillar is inserted into this through hole, but it is usual that the lower end of the pillar is also fixed to the foundation floor surface with bolts It is.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional system floor, when a partition is provided, it is necessary to fix the base to the floor with bolts, and to partition the floor. When erecting a support post on the floor, the lower end of the post is fixed to the floor panel with bolts, etc., and the upper end is fixed to the ceiling panel with bolts. And the construction is difficult. In addition, even if the floor panel is provided with a through hole in advance so as to correspond to such an option, the workability is poor because the lower end of the column is also fixed to the foundation floor surface with bolts,
Further, the structure in which only the lower end of the column is fixed by bolts is insufficient in strength.

The present invention has been made in view of the above circumstances, and an object thereof is to enable a pole to be erected on a floor panel with a simple structure, to be excellent in strength, and to use the pole for multiple purposes. It is to provide a system floor that can be used.

[Configuration of the Invention] (Means and Actions for Solving the Problems) A system floor according to the present invention is laid on a foundation floor surface, has struts at four corners on an upper surface, and has a center strut at a central portion. A base, a floor panel supported by the support of the floor base, and having a through hole at the center thereof facing the center support; a floor panel inserted into the through hole of the floor panel and supported by the center support. And a pole supported detachably on the pole support member and standing on the upper surface of the floor panel.

The center support is preferably in the shape of a rectangular frame, and is provided with a concave groove on four side walls thereof, and the pole support member has a plurality of support legs engaged and supported by the concave groove. And

Preferably, the pole support member has a bottom portion that is fixed to the floor base through a through hole of the floor panel and a support portion that protrudes upward from the floor panel and supports the pole.

The pole preferably has an insertion portion inserted inside the pole support member, and a flange portion joined to the upper surface of the floor panel.

The pole is preferably an information pole to which an information communication device is attached.

The information pole preferably also serves as a support leg of the table.
