BOX BEAM TERMINALS

摘要

Gundrail installation designs are described that incorporate a box beam rail as the structral rail member. The box beam rail member (62) may have an open cross-section or a closed cross-section. An impact head (102) is provided to bend and deflect the rail member during an en-on collision, allowing the rail member to be deflected away from the roadway and out of the path of an end-on impacting vehicle. The impact head includes a striking face (18) and a chute (104) portion that receives the box beam rail member therewithin. In addition to bending and deflecting the rail member, the impact head may also include a flattening (112, 124) section for flattening the rail member.
