Abstract

The invention discloses a guardrail terminal. The guardrail terminal comprises a connecting assembly (2) and two or more pre-deformation energy storage plates (1). The pre-deformation energy storage plates (1) are provided with energy storage parts (101). The energy storage parts (101) can be deformed when under pressure so that the kinetic energy of a vehicle can be offset. The connecting assembly (2) is fixedly connected with a guardrail. The pre-deformation energy storage plates (1) are arranged on the connecting assembly (2) in a sleeving mode, and thus the pre-deformation energy storage plates (1) can move and be extruded with each other on the connecting assembly (2) when under pressure. The end, away from the guardrail, of the connecting assembly (2) is fixed to the foundation. According to the guardrail terminal disclosed by the invention, a lot of energy can be released in the vehicle collision process to offset the kinetic energy of the errant vehicle, and thus the personal safety of personnel in the vehicle is protected more effectively.

Description

technical field [0001] The present application relates to the technical field of highway anti-collision facilities, and more specifically relates to a guardrail end. Background technique [0002] Guardrails are the main facilities to ensure road traffic safety, and play an important role in preventing vehicles from rushing off the road, falling into ravines and deep valleys, and reducing the serious consequences of accidents. The end of the guardrail is a special end structure set at the beginning or end of the standard section of the guardrail. It has a good energy-absorbing effect on the collision of out-of-control vehicles, and provides buffer space and time for the collision, thereby reducing the driving force caused by vehicle collisions. The extent of injuries to personnel and the extent of vehicle damage. [0003] The guardrails in the prior art generally use the end of the guardrail of the wave beam. The structure of the end of the guardrail cannot absorb the kineti...
