Abstract

Improvements made in the manufacture of paving stones, especially made of concrete, which can be assembled to form interlocking gears, characterized in that the paving that occupies an imaginary, rectangular, almost square shape presents, on one side of the shape in plan, a gap in trapezoidal shape, which is arranged symmetrically with respect to a line of symmetry that cuts the side of the plan form at a right angle, because towards the side of the plan form which is opposite to the first side of the plan form extends a projection symmetrical with respect to the line of symmetry, produced by lateral holes, that in its front part, in a zone in the shape of a trapezoid has the same shape and very approximately the same area as the hole, because the corners of the paving stones formed between the first side of the plan form and the two remaining sides of the plan form are chamfered accordingly, and because each hole is limited between the root of the projection and one of the last sides of the plan form by two frontal planes, of which the one extends perpendicularly to the line of symmetry and the other inclined with respect to it, coinciding these frontal planes in length and position angular with the two frontal planes located at the opposite end of the line of symmetry next to the gap.
