Method and device for laying access floors, and access-floor support

Abstract

To simplify and speed up the laying of access floors formed of floor panels (6) laid on supports (5) set out in a regular pattern, an ancillary plane (4) extending over a field (3) of grid points (2) is levelled up at a distance from the subfloor or structural slab (1). A device (10) with a frame (11) and outriggers (12) is used to define the ancillary plane, to hold temporarily a multiplicity of supports (5) and introduce them simultaneously. The supports are then simultaneously adjusted in height and fixed on the grid points (2) in accordance with the respective distance between the ancillary plane and the (uneven) subfloor (1). The supports are then released from the device (10), the device is removed, and the panels (6) are laid on the accurately positioned head pieces of the supports. Various embodiments of the method, the device (10), and particularly suitable prefabricated supports (5) are described. In the latter, the head piece and base are loosely guided relative to each other and can be moved axially relative to each other without the need of rotating either the head piece or the base. After height adjustment of the supports, means of retention and fixation are used to fix the relative position of the parts to each other.
