Abstract
A module of road safety barrier for contacting and redirecting an errant vehicle includes a first beam, a second beam, and uprights that support them. The first beam has a first longitudinal part projecting laterally with respect to the uprights and also has a second longitudinal part projecting laterally with respect to the uprights, on the opposite side of the uprights with respect to the first longitudinal part. The first longitudinal part and the second longitudinal part are each joined to both of the uprights by means of permanent joints and are joined to one another by welds or brazing so as to form an internally hollow beam with longitudinal slots. In manufacturing, the whole module is galvanized.

A module of a road safety barrier for contacting and redirecting an errant vehicle, comprising:
- a first beam;
- a second beam;
- uprights that support the first beam and the second beam, each upright comprising a lower end which is configured to be fixed to the ground and an upper end, opposite the lower end;
- wherein:
- the first beam extends longitudinally from a first upright to a second upright in order to contact and redirect an errant vehicle and is joined between the lower ends and the upper ends, detached therefrom;
- wherein the second beam is joined to the upper ends;
- wherein the first beam comprises a first longitudinal part which projects laterally with respect to the uprights;
- the first beam comprises a second longitudinal part which projects laterally with respect to the uprights, on the opposite side of the uprights with respect to the first longitudinal part;
- the first longitudinal part and the second longitudinal part are both joined to the first upright and to the second upright by means of joints of a permanent type,
- wherein the first longitudinal part and the second longitudinal part are joined to one another so as to form an internally hollow beam with welds or brazing, longitudinally spaced so as to form longitudinal slots between the first longitudinal part and the second longitudinal part, each longitudinal slot extending between two welds or brazing longitudinally spaced.
A method for realising a module of a road safety barrier comprising steps of:
- providing a first longitudinal part and a second longitudinal part;
- providing a second beam;
- providing uprights comprising a lower end which is configured to be fixed to the ground and an upper end, opposite the lower end;
- joining the longitudinal ends of the first longitudinal part and the second longitudinal part to a first upright and to a second upright, in a detached position from the lower ends and upper ends, by means of joints of a permanent type;
- joining the second beam to the upper ends of the first upright and the second upright;
- reciprocally joining the first longitudinal part and the second longitudinal part so as to form a first beam, which is hollow, for contacting and redirecting an errant vehicle;
- subjecting the module to a galvanizing treatment with the first longitudinal part and the second longitudinal part joined;
- wherein the steps of providing a first longitudinal part and a second longitudinal part and joining the longitudinal ends are configured in such a way that both the first longitudinal part and the second longitudinal part project laterally with respect to the uprights on sides that are opposite one another,
- wherein during the step of reciprocally joining the first longitudinal part and the second longitudinal part, the first longitudinal part and the second longitudinal part are detached from one another and are joined by welding or brazing at several longitudinally spaced points so as to form longitudinal slots between the first longitudinal part and the second longitudinal part.
