Barrier system

摘要

A barrier system including a guardrail, a support to hold the guardrail in position and a fastener to attach the guardrail to the support, wherein the support has a weakened zone to facilitate the fastener releasing from the support when the support is subject to impact forces.

主权项

1. A vehicle containment barrier system, comprising:
a plurality of supports that each have a top end and a bottom end, wherein the bottom end is configured to be placed into the ground and the supports generally vertically oriented, wherein the supports each include a front side and a rear side, and wherein each support includes:
a tab formed in the front side that is defined by a reduced thickness area in the support comprising a recessed channel around the outer periphery of the tab, anda connection portion, wherein the connection portion is located at a bottom region of the tab and the reduced thickness area is positioned at sides and a top region of the tab; a guardrail that is coupled to the supports so as to extend laterally across the front sides of the supports; and a plurality of connectors that couple the guardrails to the supports at the tabs, wherein the connectors are located within the outer periphery of the tabs; and wherein the reduced thickness area has a shear strength that is less than a connection force between the connector with the tab such that when a vehicle strikes the guardrail at the front side of the supports, the reduced thickness area separates from the support causing the sides and top region of the tab to move outwardly away from the support while the bottom region of the tab remains connected to the support and the tab remains connected to the guardrail, thereby suspending the guardrail above the ground while the supports move away from their generally vertical orientation as the vehicle impacts the barrier system.
