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.

L'invention concerne un revêtement de sol composé de pièces moulées pentagonales en béton (F¿1?) assemblées les unes aux autres au moyen de joints et a pour but de conférer à un tel revêtement de sol, un aspect analogue à un revêtement en pierres brutes de formes irrégulières, tout en assurant une fabrication simple des pièces moulées et une pose simple de celles-ci. A cet effet, il est prévu que chaque pièce moulée présente deux côtés rectilignes adjacents et d'égale longueur (1, 2) formant un angle obtus entre eux, deux côtés concaves (3, 4) raccordés aux précédents, d'égale longueur, de même courbure et, entre ces deux côtés concaves, un côté convexe (5) dont la longueur est le double de celle des côtés concaves (3, 4) et d'une courbure correspondant à celle des côtés concaves. Trois de ces pièces forment, à chaque fois, un groupe de trois éléments dont les côtés rectilignes (1, 2) viennent mutuellement en contact en vue de former un joint en étoile (6). Les côtés convexes (5) situés à l'extérieur d'un groupe de trois viennent en contact avec les côtés concaves du groupe de trois voisins et inversement.
