The connection structure of the upper end plate 12 and the upper end of the main reinforcement 14 is the same as the connection structure of the lower end plate 13 and the lower end of the main reinforcement 14. In this embodiment, the connection structure of the lower end plate 13 and the lower end of the main reinforcement 14 is taken as an example for description. Both ends of the main reinforcement 14 are provided with a upset head 141, and the diameter of the upset head 141 is greater than the diameter of the main reinforcement 14. The lower end plate 13 is provided with an anchoring hole 131 having a diameter greater than the diameter of the upset head 141.
