Pedestal structure for raised access floors

摘要

A pedestal comprises a support 20 having a screw bolt 21, its upper end having an adjusting hole 23, its lower end having an H-shape and being connected to a base 22, the base having a protruding portion 27 with a central pivot hole 271. Also provided is a fixing seat 30 having an interiorly threaded through hole 31, connected by screwing with the upper end of the screw bolt. The fixing seat supports a plurality of raised access floor panels. A socket set screw 40 is screwed into the through hole of the fixing seat, it has a vertical (in use) though hole having a diameter larger than that of the adjusting hole 23 of the screw bolt. In use, an adjusting tool extends through the through hole in the socket set screw to engage with the adjusting hole of the screw bolt, rotation of the screw bolt permits vertical displacement of the supporting seat relative to the fixing seat. The socket set screw is rotated into abutment with the screw bolt in order to prevent movement of the screw bolt.
