Abstract

Si descrive un braccio distanziatore per ancorare il nastro o corrente di barriere stradali ai montanti di sostegno, il quale braccio assorbe e dissipa energia derivante dall'urto di un veicolo per propria conformazione, mantenendo lo stesso nastro sostanzialmente in una posizione operativa anche in caso di collisione di mezzi pesanti. A tale scopo il braccio è indebolito da zone a resistenza ridotta, programmate per deformarsi in modo differenziato, le quali provocano, a seconda dei casi, all'istante della collisione, mutue rotazioni e/o scorrimenti longitudinali tra le parti adiacenti in maniera correlata allo sforzo cui il distanziatore viene sottoposto.A spacer arm is described for anchoring the belt or current of road barriers to the support uprights, which arm absorbs and dissipates energy deriving from the impact of a vehicle due to its conformation, keeping the belt substantially in an operating position even in the event of collision of heavy vehicles. For this purpose, the arm is weakened by areas of reduced resistance, programmed to deform in a differentiated way, which cause, at the instant of the collision, mutual rotations and / or longitudinal sliding between the adjacent parts in a manner related to the stress to which the spacer is subjected.
