Boundary barrier, especially for traffic lanes, pavements or road works

摘要

The limiting barrier consists of hollow molded bodies (1) made of plastic on the bottom with a base (2), which have an upper part (4) which is narrower in relation to their lower part (3) and which with its side walls (5) extends into the wider base (2) having lower part (3) and which are provided on one end face (6) with a partially cylindrical convex and on the other end face (6 ') with a corresponding partially cylindrical concave end face (7, 7'), the side walls (5 ) in the transition area (8) to the concave end face (7 ') converge into this. In the concave end face (7 ') is a horizontally extending, open on both sides and accessible from above latching groove (9) and on the convex end face (7) at the same height extending over the entire arc of this end face (7) into the Locking groove (9) matching locking bar (10) arranged. Between two of these shaped bodies (1), a cylindrical shaped piece with a circumferential locking bar or groove can be arranged, or one with a Maltese cross-like cross section with locking grooves or bars in or on the partially cylindrical concave side surfaces between the arms.
