he invention relates to a metal parapet meant for separating traffic flow on roads. The said parapet is composed of: 1) vertical beams arranged at regular intervals and consisted of the a U-shaped section whose area increases while moving from the upper to the lower section, of the metal plate resting on the two edges determined by the free ends of the two members of the U-section and the additional angular L-shaped sections which are equal in number to the horizontal, parallel hollow beams and welded on the aforementioned metal plate so that the one member of the foregoing L-shaped sections can be positioned on the surface of the metal plate and in the direction of the beam's height while the other member is perpendicularly positioned onthe surface of same plate operating, thus, as a support of the horizontal parallel hollow beams; 2) three horizontal parallel hollow beams encountered on the same vertical plane and interconnecting the adjoining beams; 3) a cage anchoring the beams on the ground, and which cage is composed of a metal plate, anchor rods (anchoring elements) having the form of an inversed walking stick and screws fixing the plate on the beams. |
