Abstract

Abstract A readjustable floor system permits cables C of various sorts to be freely distributed therein and is capable of very flexibly coping with expansion and relocation of cables of various sorts already distributed. This system is constructed by forming unit members 3 of an approximately U-shaped cross section each composed of a pair of floor member-supporting joists 1 disposed parallelly on the surface of a floor 13 in an opposed relation to each other across a fixed interval and a bottom plate 2 laid to interconnect the lower parts of the joists, defining a space 4 for distribution of cables and pipes inside the unit members, partitioning the space through an antistatic sheet 9, and detachably mounting unit floor boards 6 one each on top of the unit members.
