Connection joint of concrete filled steel tubular column and enclosed U-shaped steel concrete composite beam
The invention provides a connection joint of a concrete filled steel tubular column and enclosed U-shaped steel concrete composite beam; in order to save materials and solve the problem that since a connection plate at the connection part of a composite beam bottom plate and a steel pipe outwards extends, an indoor corner has a convex angle to influence the beautiful sense, an inner partition plate is arranged at a position corresponding to a U-shaped steel bottom plate in the steel pipe, and the periphery of the inner partition plate is welded with the inner wall of the steel pipe. Sleeves which are movably connected with the end parts of hogging moment reinforcing steel bars are correspondingly arranged at two relative ends in the steel pipe along the length direction of the composite beam respectively; and the sleeves are welded with the outer wall of the steel pipe. The joint is capable of relieving the condition that the bearing capacity of the steel pipe is weakened due to hole forming in the side wall of the steel pipe; the welding workload is reduced; construction is facilitated; and assembly is realized. In order to effectively transmit a load, a horizontal stiffening plate is fixedly welded at positions corresponding to the sleeves in an inner cavity of the steel pipe, and the welding workload in field is reduced; a U-shaped steel side plate is connected with the wall of the steel pipe by adopting high-strength bolts through connection plates; the connection plates are connected with the wall of the steel pipe by angle welding; and welding is completed in a factory.
