<p>A new guardrail comprises spaced out uprights or posts (12; 112 ...), on which is carried, by means of deformable spacer elements (20; 120 ...), a horizontal rail (30; 130 ...) comprising two strips (32, 34; 132; 134 ...) with a double wave, situated opposite each other, connected to each other at intervals by means of ribs or cross stiffening brackets (36; 136 ...) bolted to the strips. The strip and the ribs are made of steel. The spacer has a straight lower inclined side and a curved or bent upper side. In some variants the barrier has one or two continuous upper elements (150) at the top having considerable bending stiffness. <IMAGE></p> |
