Node for connecting concrete-filled steel tube column and external wrapping U-shaped steel concrete composite beam
The invention provides a node for connecting a concrete-filled steel tube column and an external wrapping U-shaped steel concrete composite beam. The node facilitates the pouring of concrete in a steel tube, easily guarantees pouring quality of concrete in a node area, is favorable for welding operation and easily guarantees weld seam quality. An outer annular plate is welded to the outer side of the steel tube at the position of a U-shaped steel base plate, the two opposite ends inside the outer annular plate in the length direction of the composite beam are connected with the U-shaped steel base plate having undergone limb cutting through butt joint weld seams, the weld seams do not crack easily, the connecting strength is high, and the vibration resistance is good. Sleeves capable of being movably connected with the ends of a hogging moment steel rib are arranged at the two opposite ends inside the steel tube in the length direction of the composite beam respectively; and the sleeves are welded to an outer wall of the steel tube. The structural type can reduce the weakening of steel tube bearing capacity caused by hole opening in a side wall of the steel pipe, the welding workload is reduced, and the construction and assembly are facilitated. To effectively transmit a load, horizontal reinforcing plates are fixedly welded to the positions of a steel tube inner cavity corresponding to the sleeves.
