Double-floor design

摘要

A double-floor design with flooring panels and a support structure to be placed on a sub-floor on which the flooring panels can be laid abutting one another edge to edge and spaced from the sub-floor. The support structure includes support rails which extend below the joints between the flooring panels along the joints. The flooring panels and support rails include devices for vertically fitting the flooring panels onto the support rails, wherein the edge faces of the flooring panels forming the joints are pressed together horizontally.

1. A double-floor construction, comprising: floor plates; and a support structure to be built on a subfloor, the floor plates being placeable on the support structure with edges of the floor plates abutting each other, wherein
the support structure comprises support rails, which extend underneath the butt joints between the floor plates and along the butt joints and which are held at a certain distance from the subfloor by uprights of the support structure, the uprights being configured to be arranged underneath corners of the floor plates; and the floor plates and the support rails comprise contrivances to allow the floor plates to be set vertically down onto the support rails under horizontal compression of the edges of the floor plates forming the butt joints, wherein each of the support rails comprises a horizontal channel extending under an associated butt joint, wherein the contrivances of the floor plates are hooking sidepieces formed on the edges of the floor plates, the hooking sidepieces being vertically insertable into the channel so that the hooking sidepieces of the abutting floor plates lock into place within the channel when vertically inserted and secure the floor plates against movement in both vertical directions by locking projections.
