Title
(EN) IMPROVEMENTS IN ROAD BARRIERS
(FR) AMELIORATIONS DE BARRIERES ROUTIERES
Abstract
(EN)
A road barrier comprises an elongate container configured to receive and hold a volume of water. The barrier is made from a plastics material and has a base, end walls, each of the end walls having means for releasably coupling the barrier in end to end relation with a like barrier, side walls, and a top. The barrier includes a water fill hole in its top to enable the barrier to be filled with water and a discharge hole near its base for enabling water to be discharged from the barrier. The side walls of the barrier define a lower face which is inclined and extends outwardly away from a central longitudinal axis of the barrier, a step portion which extends inwards towards the central longitudinal axis of the barrier and an upper inclined face which extends away from the central longitudinal axis of the barrier. This contouring of the side wall helps to prevent vehicle tyres from riding up the sides of the barrier. The road barrier includes a plurality of mounting means, located at each side of both ends of the barrier adjacent the ends of the barrier, at the base of the barrier and also at the top of the barrier adjacent the upper inclined faces. The mounting means are used for mounting latch plates to the barrier to enable one barrier to be connected on both sides top and bottom to the mounting means of another opposed barrier in end to end relation. The barrier also includes a visible float to indicate whether the barrier is full of water or not.

L'invention concerne une barrière routière constituée d'un contenant allongé conçu pour recevoir et conserver un certain volume d'eau. La barrière, en matière plastique, a une base, des parois d'extrémité, lesdites parois étant, chacune, pourvues d'un moyen de coupler détachable, bout à bout, une barrière semblable, des parois latérales et d'un sommet. La barrière a également, à son sommet, un trou de remplissage d'eau, ce qui permet de la remplir d'eau, et, près de sa base, un trou pour vider l'eau qu'elle contient. Ses parois latérales définissent une face inférieure inclinée qui s'étend vers l'extérieur, éloignée d'un axe longitudinal central de la barrière, une partie en gradin qui s'étend à l'intérieur vers l'axe longitudinal central de la barrière et une face supérieure inclinée qui s'étend éloignée dudit axe. Ce profilage de la paroi latérale permet d'empêcher les pneus d'un véhicule de monter sur les côtés de la barrière. La barrière routière comporte plusieurs moyens de montage, placés sur chaque côté des deux extrémités de la barrière jouxtant les extrémités de la barrière, à la base de la barrière et au sommet de la barrière jouxtant les faces inclinées supérieures. Les moyens de montage servent à monter des plaques de blocage sur la barrière, ce qui permet de relier, bout à bout, une barrière sur les deux côtés supérieur et inférieur aux moyens de montage d'une autre barrière opposée. La barrière comprend également un flotteur visible qui indique si la barrière est pleine d'eau ou non.
