System of direct fusible anchoring for a support post of a security barrier or parapet in rigid ground

A direct fusible anchoring system for a support post of a safety barrier or parapet in rigid ground comprising:

• a base plate fixed to the post, with fixing holes in the base plate,
• one or more anchor bolts, partly embedded in the ground and rigidly fixed to the ground, so that each of the one or more anchor bolts emerges from the ground and passes through a separate corresponding fixing hole of the base plate,
• the one or more anchor bolts remaining fixed to the base plate by corresponding closure nuts and one or more fusible washers with a fusible capacity located beneath the corresponding closure nuts, wherein each of the one or more fusible washers are in the form of a longitudinal bar with a cross-section in the form of a “C”, and
• each of the one or more fusible washers having
• a central core, in a horizontal position or slightly inclined position, forming an upper face of the washer in contact with one of the corresponding closure nuts;
• two side wings, with lower ends of the side wings resting on the base plate;
• and
• at least a bolt passage hole located in the upper face of the washer, the bolt passage hole having a size less than a size of the corresponding closure nut;
• so that in the event of an impact from a vehicle against the safety barrier or parapet the bolt passage hole can be progressively deformed by the corresponding closure nut, allowing said corresponding closure nut to pass completely through the washer, wherein the bolt passage hole has a star shape, with a central gap of a size less than the size of the corresponding closure nut;
• and a plurality of elongated holes in the form of concentric radii connected to the central gap.
