The two side plates of the U-shaped steel column are distributed with side connection recesses, and the side connection recesses of the same group are connected to each other through connecting holes. Both ends of the impact-resistant rod body are set as serial connection parts, and the serial connection parts are provided with circular holes. Strong torsion springs are installed in the upper and lower ports of the circular hole. The circular hole is connected with the serial pin rod part located in the side connection recess.

[0005] Preferably, a foundation connecting plate is welded to the bottom end of the U-shaped steel column.

[0006] Preferably, the cross-section of the side connection recess is L-shaped, and the inner wall of the side connection recess is fixedly connected to one end of the adjacent strong torsion spring.

[0007] Preferably, the inner diameter of the port of the circular hole is larger than the inner diameter.

[0008] Preferably, the corresponding parts of the serial connecting pin rod are assembled and fixed together in the connecting hole.

[0009] Compared with the existing technology, the advantages of the present invention are: a strong torsion spring is installed at the connection between the impact-resistant rod body and the serial pin rod part located in the side connection recess, which has high-strength impact buffering and enhances the protection effect. The serial pin rod is used to be connected in series with the corresponding parts of the impact-resistant rod body on the same side in sequence, which saves the operation of installing and connecting one by one and has high installation efficiency.
