[0002] The beam-column connection structure includes a beam-through type beam-column connection structure and a column-through type beam-column connection structure.

[0003] The rigid connection between the steel columns and steel beams of the existing landscape trestles mostly adopts a column-through type beam-column connection structure connected by welding or bolts. Since the components of the landscape steel structure trestles are relatively small, the column-through connection method causes the beams to be disconnected, which will result in too many connection nodes at the beam-column connection and small operating space, which will eventually lead to an extension of the construction period. At the same time, landscape trestles are usually single-column cantilevers with rigid connections at both ends, and the column spans are relatively dense, resulting in cumbersome rigid connection nodes and high maintenance frequency of outdoor open-air components. The existing connection methods are difficult to meet the requirements of construction period, simple construction and rapid replacement in the later stage.

[0004] Therefore, how to improve the construction convenience and maintenance and replacement efficiency of the beam-column connection structure has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0019] The first step is to weld a top plate and a transverse reinforcement rib at the top of the steel pipe column;

[0020] The second step is to lift the steel beam to the top of the column top plate, and lower the steel beam so that the node connection plate is inserted into the avoidance slot hole of the column top plate along the vertical direction;
