There are two groups on the upper and lower sides of the groove. The movable clips are clamped on the grooves. The movable clips are opened with a through hole, and the bottom of the movable clips is movably installed with a rotating shaft. The bottom of the movable clips is fixedly connected with a fixed stack. The upper and lower slopes of the fixed stack Screws are all screw-connected, and railings are fixedly connected to the fixed pile by screws.

Preferably, the roadbed covers and tightly presses the bottom bar, and the bottom bar is in the shape of a cuboid.

Preferably, the inclined support rod is obliquely welded to the bottom rod and the support leg to form a triangular structure.

Preferably, the threaded part of the support leg is exposed out of the road.

Preferably, the movable clip is fixedly connected to the fence post through the through hole of the screw.

Preferably, threaded holes matching the screws are provided on the fixing stack.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model directly fixes the bottom bar on the roadbed, laying a good foundation for the later construction of the guardrail. The guardrail has a firm foundation and a high safety factor, which saves a lot of labor and improves work efficiency. And the build quality of the guardrails, installing the guardrails on the support legs is quick, easy, safe and convenient.
