Post footing

摘要

This invention presents a security barrier post (10) which has an underground footing (12) and an impact post (14) that extends above the surface. The underground footing (12) has a substantially vertical tubular steel shaft (16) having an opening at its lower end on an impact facing side and a steel foot box (18) aligned with the opening. A bottom plate (20) is provided to which the shaft (16) and said foot (18) box are attached. A spring steel back plate (22) is arranged adjacent and perpendicular to rear facing side of the shaft (16), and extends to at least one side of it. The back plate (22) is located at a position that is flush with or slightly below the surface in which the footing is buried. The impact post (14) has at least a first spring steel element (32) which is L shaped, and at least one packing element (34, 36, 38) located behind the first element (32) to retain it in a position in which it extends into the foot box (18).
