PURPOSE: A guardrail is provided to minimize damage due to an external shock by reinforcing the joint of a rail and a post and to prevent corrosion by not exposing a fixture. CONSTITUTION: A guardrail comprises a post(10), a rail(20), an internal rail(40), a fixture(50), and a fastening guiding device(70). Both ends of the internal rail are inserted into a rail joint space(22) and are fixed by a fixing unit(30). The fixture fixes the rail and the post. One side of the fixture is formed with a hanging unit and the other side of the fixture penetrates the post to be fixed. One side of the internal rail is formed with a cut part(42) for inserting the hanging unit. An external finishing plate with a joint hole is installed in the joint of the rail. |
