A road steerable crash pad

Abstract

The invention provides a highway anti-collision pad with a guide function. The highway anti-collision pad with a guide function comprises a plurality of vertically-arranged slidable frames with the frame faces perpendicular to a collision direction line, energy absorption components arranged between the adjacent slidable frames, wave-shaped protection plates arranged on the left and right sides of the slidable frames in the collision direction, and a fixed end arranged at the tail end of the anti-collision pad with a guide function in the collision direction. The slidable frames are connected in series through steel wire ropes, the fixed end is fixedly connected with the ground or a concrete cushion, the wave-shaped protection plates are connected end to end in a lap joint mode in the collision direction, and each energy absorption component comprises two end plates fixedly connected with two corresponding adjacent slidable frames in parallel respectively, and a plurality of side plates which are fixedly and vertically arranged between the end plates and are perpendicular to the end plates. When a vehicle collides with the anti-collision pad with a guide function, the side plates generate half-wave deformation. The highway anti-collision pad with a guide function is simple in structure, not likely to fall apart and good in energy absorption effect and can protect and guide vehicles in high-speed collisions.

Description

technical field [0001] The invention relates to the field of road traffic safety facilities, in particular to a guideable crash pad for roads. Background technique [0002] With the rapid development of my country's expressway traffic, people are paying more and more attention to traffic safety, and some traffic safety products have gradually been applied. The guideable crash pad is one of the widely used products. It mainly absorbs energy through the interior. The crushing of the structure absorbs the kinetic energy of the vehicle and provides space and time for buffering the collision of the vehicle, so as to reduce the injuries of the drivers and passengers due to the impact of external forces. [0003] At present, my country's design requirements for steerable crash pads all come from the newly issued regulations "Safety Performance Evaluation Standards for Highway Guardrails" JTG B05-01-2013. Due to the low protection level of the existing crash pads in China, the maxim...
