摘要： A terminal portion of a guardrail safety system includes a terminal portion of a guardrail beam having a downstream end and upstream end. The terminal portion of the guardrail beam slopes from a height appropriate for redirecting an errant vehicle to a height proximate the surface of the ground at an upstream end of the terminal portion.Support posts are installed adjacent a roadway in spaced apart relation to one another and are coupled to the terminal portion of the guardrail beam. A terminal support post is installed adjacent the roadway at an upstream end of the terminal portion of the guardrail beam. The terminal support post couples to an upstream end of the terminal portion of the guardrail beam by a resistive, tensile coupling that maintains tension in the terminal portion of the guardrail beam. The resistive, tensile coupling is maintained between the terminal support post and the guardrail beam during an end-on or re-directive impact by a vehicle. However, the resistive, tensile coupling between the terminal support post and the guardrail beam is released during a reverse-direction impact.

摘要： Devices and methods for supporting guardrail terminal installations that incorporate safety end treatments such as the GET and the SRT. Preferred embodiments are described wherein guardrail terminal installations are primarily anchored to the ground using weak support posts that are preferably made of metal. The ends of the guardrail installation are secured to the ground using breakaway posts. In operation, the weak posts permit the central portion of the guardrail installation to contain and redirect the vehicle during a lateral collision to the rail member. The anchorage provided by the breakaway end posts helps prevent the guardrail from being excessively displaced, thus preventing the impacting vehicle from breaking through the guardrail. In operation, guardrail terminal assemblies constructed in accordance with the present invention provide an improved support system for the rail member which is more forgiving than conventional strong post anchorages, thereby providing an improvement in safety. At the present time, the invention has particular application in some non-U.S. countries, where it is required or highly preferred that metal support posts be used either completely or primarily within guardrail installations. However, the invention is also applicable to installation within the United States.

摘要： A guardrail safety system includes a guardrail beam operable to contain and redirect an errant vehicle to prevent the vehicle from leaving a roadway. At least a portion of the guardrail beam includes a thrie beam. A support post is coupled to the guardrail beam and includes a lower portion, a mid portion, and an upper portion. The lower portion is installed below grade adjacent the roadway. The mid portion lies substantially adjacent the grade and is weakened about a first axis without being substantially weakened about a second axis that is generally perpendicular to the first axis. An upper portion is releasably coupled to the guardrail beam such that the upper portion is uncoupled from the guardrail beam when the mid portion yields about the first axis.

摘要： In accordance with a particular embodiment of the present invention, an end treatment of a guardrail safety system includes a terminal portion of a guardrail beam that has a downstream end and an upstream end. The terminal portion of the guardrail beam slopes from a first vertical height appropriate for redirecting an errant vehicle to a second vertical height proximate the surface of the ground at an upstream end of the terminal portion of the guardrail beam. A flattening portion forms a channel through which the terminal portion of the guardrail beam is disposed. A vertical dimension of the channel is greater at a downstream end of the flattening portion than at an upstream end of the flattening portion. An impact plate is connected to the flattening portion for engaging an impacting vehicle at an end of said guardrail beam. During an end-on impact, the impact plate and the flattening portion are advanced longitudinally along the guardrail in a downstream direction by the vehicle. The advancement of the impact plate and flattening portion dissipate energy to decelerate the impacting vehicle. As downstream portions of the guardrail beam are forced into the flattening portion, the guardrail is flattened vertically.

摘要： In accordance with a particular embodiment of the present invention, a guardrail safety system includes a guardrail beam having a length-of-need (LON) portion spanning between two terminal portions. The guardrail safety system also includes a plurality of guardrail support posts in spaced apart relation to one another. At least a portion of the plurality of support posts include a lower portion for installing below grade adjacent the roadway, a mid portion that lies substantially adjacent the grade, and an upper portion releasably coupled to the LON portion of the guardrail beam. The mid portion includes a weakened section operable to weaken the support post about a first axis without substantially changing the behavior of the support post about a second axis that is generally perpendicular to the first axis.

摘要： A guardrail extruder terminal for flattening a folded or W-beam guardrail and bending the guardrail to dissipate the energy of a vehicle impacting the end of the guardrail includes a feeder chute. The feeder chute is provided with an inlet in which the guardrail is positioned. The feeder chute extends into a terminal housing, and is in communication with an extruder or flattening throat. The flattening throat is of a smaller width than the feeder chute to flatten the guardrail. A bending member is also provided in the terminal to bend the guardrail in an curvilinear arc away from the impacting vehicle. Also included is a cable anchor releasably mounted on the guardrail. A cable extends from the cable anchor to a first post located at the end of the guardrail. The cable anchor includes lugs that release from the guardrail upon engagement of the extruder terminal with the cable anchor. To prevent twisting, bending or rotation of posts holding the guardrail as the extruder terminal and impacting vehicle move down the guardrail during a collision, a groundline cable extends through bores in each post. In an alternative embodiment, the extruder throat includes side walls defined by curvilinear extruder plates. The curvilinear extruder plates minimize the engagement of the guardrail with the side walls of the extruder throat during impact by a vehicle to reduce the frictional forces experienced during initiation of the flattening process.

摘要： A guardrail extruder terminal for flattening a W-beam guardrail and bending the guardrail to dissipate the energy of a vehicle impacting the end of the guardrail includes a feeder chute. The feeder chute is provided with an inlet in which the guardrail is positioned. The feeder chute extends into a terminal housing, and is in communication with a flattening throat. The fattening throat is of a smaller width than the feeder chute to flatten the W-beam. A bending member is also provided in the terminal to bend the guardrail in an curvilinear arc away from the impacting vehicle. Also included is a cable anchor releasably mounted on the guardrail. A cable extends from the cable anchor to a first post located at the end of the guardrail. The cable anchor includes lugs that release from the guardrail upon engagement of the extruder terminal with the cable anchor. To prevent turning or rotation of posts holding the guardrail as the extruder terminal and impacting vehicle move down the guardrail during a collision, a groundline cable extends through bores in each post.
