摘要

The height adjustable support for a raised floor on a building has a base (1) fixed to a foundation and an identical section (3) attached to the floor tiles. The two are connected by a tube (2), which is double threaded (2.2) on its exterior. The base and upper sections each have a single thread (1.2) engaging with the tube to allow adjustment of their spacing when the tube is rotated. The base and upper section can have reinforcing ribs (1.4).
