ABSTRACT:
Construction elements each consist of a central section and two external sections, with the central section having, in addition to flat top and bottom surfaces, two parallel side walls and four, shorter side walls arranged at angles relative to the longer side walls. Pairs of the angled side walls would intersect at right angles were they to extend to the two external sections. The two external sections are cylindrical in shape and of a height less than the height of the central section, with the remaining portion of the central section having a cylindrical wall that may be thought of as a continuation of the external section. By providing the external sections with a height less than the central section, it is possible to line up the elements adjacent to each other with the external sections of adjacent construction elements overlapping in order to form a temporary curbstone or traffic control structure.
