Readjustable floor system

DETAILED DESCRIPTION One object of this invention is to provide a readjustable floor system which enables cables of various sorts to be freely distributed with an extremely simple structure.
Another object of this invention is to provide a readjustable floor system which is capable of very flexibly coping with expansion and relocation of already distributed cables of various sorts with a very simple structure.
To accomplish the objects described above, according to this invention, there is provided a readjustable floor system comprising unit members of an approximately U-shaped cross section each composed of a pair of floor member-supporting joists disposed parallelly on a floor surface in an opposed relation to each other across a fixed interval and a bottom plate laid to interconnect the lower parts of the pair of floor member-supporting joists, the unit members defining therein a space for distribution of cables and pipes, a plurality of antistatic sheets each having opposite ends fastened to the pair of floor member-supporting joists for vertically partitioning the space, and unit floor boards detachably mounted one each on top of the unit members.
According to this invention, there is also provided a readjustable floor system comprising unit members of an approximately U-shaped cross section each composed of a pair of floor member-supporting joists disposed parallelly on a floor surface in an opposed relation to each other across a fixed interval and a bottom plate laid to interconnect the lower parts of the pair of floor member-supporting joists, the unit members defining therein a space for distribution of cables and pipes, a plurality of antistatic sheets each having opposite ends fastened to the pair of floor member-supporting joists for vertically partitioning the space, each of the antistatic sheets concurrently serving as a heat-transfer sheet and having a groove-shaped receptacle, unit floor boards detachably mounted one each on top of the unit members, and a plurality of thermal medium-circulating pipes each distributed across the groove-shaped receptacle of the heat-transfer sheet
