System of prefabricated concrete elements for constructing paths

Claim 1

A combination of prefabricated concrete elements for constructing paths in the form of walks and cycle paths and the like for light traffic and having a predetermined width corresponding to normal minimal width N, the combination of prefabricated concrete elements adapted to rest on the ground and extend at least on part above the ground, comprising a first group of prefabricated concrete elements comprising flat, four-sided slabs for the straight sections of the path, and a second group of prefabricated concrete elements consisting of flat radius slabs for forming the curved sections of the path, said first group of elements comprising four sets of slabs each slab having at least one curb forming end surface, the end surface of the first set being vertical, the end surface of the second set being straight bevelled the end surface of the third set of slabs being obliquely bevelled towards a first opposite corner and the end surface of the fourth set being obliquely bevelled towards a second opposite corner; said second group comprising a first set of radius slabs and a plurality of sets of flat radius slabs each having a large arc and a small arc concentric with each other, the slabs in the first set of said second group having a predetermined radius which is equal to said normal width N, each of the remaining sets having slabs respectively which increase serially in radius equal to the radius of the immediately preceding set plus the normal minimal width N, the slabs of each set of said second group having edge portions at at least one of said arcs designed to form the outer contour of the path, providing a curb-forming effect.
