Cavity flooring for concrete slabs

摘要

The floor consists of several cavity floor panels (5) which are located in a prespecified lattice over a sub-floor with allowance for spaces for installation services (4). Track-like installation material (1) is laid on the sub-floor and is provided with positioning aids (2) which receive support projections (6,7,8) in a prespecified pattern. The track-like material is a deep-drawing sheeting made of board, and the positioning aids encompass punch-outs. Installation projections (3) are located in between the positioning aids for the installation of cables and lines. These projections are each located in groups of four corresponding to the corners of a square, and are provided in a prespecified lattice.
