[0002] Existing construction engineering technologies mostly use direct exposure for placement, but this method is easily damaged by rain erosion for a long time during use. For example, a Chinese patent discloses "a connection node between a concrete column and an H-shaped steel beam", and its application number is "CN202222432787.1". It adopts the method of wrapping a steel pipe on the outside of the node area of ​​the concrete column body and setting a reinforcing ring plate on the outer wall of the steel pipe. The steel pipe is connected to a number of H-shaped steel beams through the reinforcing ring plate and a number of steel beam brackets. At the same time, an inner partition is set on the inner wall of the steel pipe corresponding to the position of the reinforcing ring plate, which improves the strength of the node. However, its structure is simple. When used outdoors, the connection node will be exposed to the outside for a long time, which will cause damage and consume the service life of the connection node.
