Floor built=up unit

摘要

The floor sections (1) are made from compressed mineral material and are mounted on supports (3). The supports consist of a spherical cup, which allows alignment of the support face. A bolt is provided which can be screwed into the cup so as to adjust the height of the support. The floor sections have stepped edges (6) so that the upper ledge of an inverted section can lie on the lower ledge of a supported section.
