Abstract

Improvements in the formative structure of pieces for paving, especially paving stones, in which an upper layer is limited in a rectangular shape, while a lower layer is provided on two opposite sides of the stone with in each case only at least one cut-out recess with respect to the upper layer, and on the other two opposite sides, of in each case at least one projection that protrudes from the upper layer and that corresponds to the recess, as well as possibly recesses, characterized in that the recesses and the projections that correspond to each other are formed by contour lines that, starting from a common point of intersection, extend to a contour line from the ground; because the contour line of the floor includes with the imaginary extension of the stone edge an angle less than or equal to 90º; Because the guide contour line that extends from the point of intersection of the contour lines to the point on the contour line that is furthest from the edge of the stone, is in a plane parallel to the lateral surfaces provided with recesses, and because the lateral displacement of the stone, motivated by the development of the contour line of guide of the stone to priest, along the contour line of guide of the corresponding recess, is in the plane of the lateral surfaces of the stone provided with cut-outs only, less than or equal to the displacement in these planes determined by the contour lines of the lateral surfaces of the stone.
