Abstract
Disclosed is a shock absorber for buffering the barrier wall of a road. According to the present invention, a horizontal inner pipe bumper is inserted into a pedestal attached to a boundary of a barrier wall and joined to the support pillar. The buffer rail transversely connected to the protruding portion of the buffer pad on the front surface of the pedestal constitutes the buffer portion of the collision portion barrier wall, and when the buffer pad adhered to the inner pipe bumper is displaced upright, tension of the elastic rail connecting the buffer pad and the elastic rail block is generated, and the guard rail of the pillar is coupled to the barrier bridging body by a connecting member.
Claims5
A shock absorber comprising:
- a pedestal having a buffer pad insertion hole (11) and a buffer pad fixing hole (12) formed on an outer circumferential surface (10) connecting anchor panels (15);
- and
- a buffer pad (60) adapted to be inserted into the buffer pad insertion hole (11) and protruded to the buffer pad fixing hole (12) provided in the pedestal,
- a rotary shaft (63) adapted to pass through the a rotary shaft through hole (64) provided in the buffer pad (60), wherein both ends of the rotary shaft (63) are horizontally connected to a rotary shaft block (62) provided in the pedestal, wherein the buffer pad (60) being up-shifted about the rotation axis (63) coupled to the rotation axis block (62) of the pedestal;
- and
- a buffer rail (30) transversely connected to a buffer socket (61) of the buffer pad (60), wherein the buffer pad (60) is up-shifted about the rotary shaft (63) of a rotary shaft block (62) when an external force applied on the buffer rail (30).
