As preferably, described sheath is fixing by reinforcing rib and cylinder welding, makes sheath more firm with being connected of cylinder.
As preferably, its two ends of described framework bolt are provided with external screw thread, and this framework bolt is an integral structure; In the framework of this framework bolt, be coated with guardrail board.Make that the structure design of framework bolt is more reasonable, bonding strength is better, and its result of use of the guardrail board that is coated is better.
As preferably, have the framework bolt hole on the described junction plate, described framework bolt is positioned at this framework bolt hole.
As preferably, described junction plate is a steel plate.
As preferably, described sheath is close to guardrail board in merging place of guardrail board, makes merging place of guardrail board very close to each other, connects more firm.
As preferably, also be provided with steel pipe, this steel pipe is weldingly fixed on an end of junction plate, and centers on the guardrail board that strap end portion is arranged on steel pipe, makes the connection of guardrail board more firm.
The utility model compared with prior art, have the following advantages and effect: overall construction design is reasonable, shock resistance is good, cost is low, long service life; Have good resiliency during vehicle collision, be difficult for the scratch automobile during collision, and greatly reduced the secondary injury of people's car; Simultaneously, the material environmentally safe of use, environmental protection.
