Floor covering of pentagonal shaped concrete slabs abutting one another with joints

摘要

The invention concerns a floor covering made up of pentagonal concrete moulded parts (F1) which fit together with joints between them. In order to give a floor covering of this kind an appearance similar to that of a floor covering made of irregularly shaped natural stones, while at the same time ensuring that the moulded parts are easy to manufacture and easy to lay, the invention calls for each part to have two adjacent straight sides (1, 2) of equal length with an obtuse angle between them, two concave sides (3, 4) of the same length and with the same curvature on each side of the two straight sides and, between the two concave sides, a convex side (5) twice as long as the concave sides (3, 4) and with the same curvature as the concave sides. Each set of three parts forms a group, the straight sides (1, 2) fitting against each other to form a star-shaped joint (6). The outwards-facing convex side (5) of each group of three fits into the concave sides of the adjacent groups of three and vice versa.
