Embodiment Construction

[0043] With respect to the figures, there is provided a terminal post generally indicated by arrow 1 having an upright portion 2 formed of a length of I-beam which, in use, is positioned on the ground. The strut 1 also has a ground engaging portion 3 at one end thereof. The ground engaging portion 3 is generally anchored in the ground (not shown). The ground engaging portion extends from one end 15 of the strut 1 to a point below two pairs of notches 4, one on each side flange 7, both level with the same horizontal plane.

[0044] The uprights 2 have holes 5 positioned in connecting webs 6 that span between side flanges 7 . A transverse stiffening member 8 is positioned on one side of the hole 5 with a slot 9 therein. The slot 9 receives the terminal end of an anchoring rope 10 having a nut 11 and a washer 12 thereon.

[0045] The transverse stiffener 8 is separated from the web 6 by a distance indicated by the double-headed arrow X via a horizontal support member 20 . The...

Abstract

A method for releasing at least one anchor cable from a terminal post in a cable barrier, after an inline impact, including deforming the terminal post from a straight upright configuration to a bent inclined configuration where the deformation creates a suitably sized aperture in the post which enables release of the anchor cable.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 2, 2011, an application number of 201110258994.3, and an invention title of "terminal support for obstacles and obstacles".
