ABSTRACT:
DESCRIPTION
The present invention relates in general terms to a flooring and more specifically to a flooring according to the preamble of claim
7
(see DE-A-2 225 892).
According to the state of the art, tiles are laid side by side until the entire surface to be floored is covered. The flooring thus obtained, which is advantageous from various points of view, has a disadvantage, however, which is revealed when it has to be removed in part, for example in order to gain access to cables, pipes and the like, which were laid at the same time as the flooring, or in order to lay these subsequently. The disadvantage is that removal of the tiles is laborious and inevitably involves the destruction of many if not all the tiles to be removed, with the consequent necessity of replacing them.
The problem underlying the present invention is to devise a flooring of the type indicated, which has structural and functional characteristics which make it possible to overcome the abovementioned disadvantage.
This problem is solved by a flooring according to claim
7
.
