Definitions

  • the present invention relates to a motorway barrier to be used on the sides of bridges, and particularly to a monolithic barrier of this type, which can be homologated in the so-called B3 class of top resistance, which is particularly suited to be used on already existing bridges or motorway viaducts, due to its reduced weight, besides on newly erected structures of this kind.
  • An object of the present invention is to realize a steel- made barrier for the sides of a bridge, which can be homologated in the class B3, with minimum production costs, employing a reduced amount of materials, and reducing the time for its erection.
  • Another object of the present invention, depending on the preceding one, is to realize the barrier in separate blocks or monolithic modules which can be directly connected to each other, which require a minimum assembling time and can be adapted to bridges of any span.
  • a further object of the present invention is to include in this new kind of barrier belonging to the B3 class, all features already advantageously used in this technical field; said features, which in part have been suitably modified, comprise among other thingsi the screw anchors with predetermined breaking threshold, the reinforcing ribs provided on the so-called “mantle” with the New Jersey profile, and the mutual connection systems among the barrier elements at the site of the expansion joints or their neighbourhood, that is, between the bays of the bridge, in order to allow displacements caused by thermal dilatation, eliminating the rise of dangerous mutual actions and stresses on the bridge top and barrier.

It will be sufficient, then, to introduce the other tube 15 (of the other module), in the sleeve 21, and move the tubes only for a short distance, in order to obtain the connection.

Abstract

L'invention concerne une barrière en acier de type New Jersey, constituée d'éléments modulaires 'monolithiques', notamment des montants et des mains courantes, obtenus à partir de tôles métalliques convenablement pliées et soudées (1, 2, 3, 4, 5, 6, 7). Des structures verticales (3, 4) sont en outre disposées tous les 1,5 mètres, ces structures présentant une largeur de 15 cm et formant un 'ensemble réticulé', ou 'treillis', dans lequel un espace (14) est ménagé afin de permettre l'insertion de moyens d'ancrage ductiles (32), utilisés pour fixer la barrière sur son support (31). Tous les 3 mètres, chaque structure verticale 's'étend vers le haut', formant le montant ou le poteau (13) destiné à soutenir la tige de la main courante (15). L'invention concerne également des raccords spécialement conçus pour relier lesdits éléments modulaires et être utilisés au niveau des joints de dilatation, entre les travées d'un viaduc.
