Steel pipe concrete column-precast concrete superposed beam assembly type building connection node

Abstract

The invention discloses a steel pipe concrete column-precast concrete superposed beam assembly type building connection node. The steel pipe concrete column-precast concrete superposed beam assembly type building connection node comprises a steel pipe concrete column and a precast concrete superposed beam, wherein the outer wall of the steel pipe concrete column is provided with a U-shaped steel tank and a prewelded outer ring steel plate in a welded manner, the prewelded outer ring steel plate is horizontally arranged and located above the U-shaped steel tank, the U-shaped steel tank is provided with a bottom plate and side plates, the bottom plate is provided with bottom steel bar clamping buckle devices, and the tops of the side plates are provided with upper flanges being folded outwards; and the precast concrete superposed beam is installed inside the U-shaped steel tank in an inserted manner, the bottom of the precast concrete superposed beam is connected with the bottom steel bar clamping buckle devices in a clamped manner, the top of the precast concrete superposed beam is welded to the prewelded outer ring steel plate, a mutual plug-in mounting area of the precast concretesuperposed beam and the U-shaped steel tank is a superposed area, and concrete is poured into the superposed area after lap joint and assembly of the precast concrete superposed beam. The steel pipeconcrete column-precast concrete superposed beam assembly type building connection node is convenient and fast to install without bolts and mold supporting, and the production and construction efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a beam-column node of a building structure, in particular to a prefabricated building connection node of a steel pipe concrete column-prefabricated concrete composite beam. Background technique [0002] Building prefabrication has the advantages of reducing on-site wet work, improving construction efficiency, reducing environmental pollution and energy consumption, and conforms to the general trend of building industrialization and industrialization development, and has been effectively applied both at home and abroad. [0003] With the implementation and practice of prefabricated building policies, many specifications and atlases have been issued in terms of prefabricated-concrete buildings, prefabricated-steel structures, and prefabricated-wooden structures. However, for prefabricated-mixed The development of structural buildings has not yet made a major breakthrough in the connection nodes, but the circular steel tube concre...

AI Technical Summary

Problems solved by technology

[0005] 1) The connection between the circular steel pipe concrete column and the steel beam is generally bolted or welded. On-site construction welding and reaming work requires a lot of work, especially the construction standard of the prefabricated structure is relatively high. Higher requirements are put forward for precision and construction quality, which greatly increases the difficulty of construction.

[0006] 2) The connection between circular concrete-filled steel tube columns and concrete beams generally adopts the forms of steel bar surrounding joints, steel bar through joints, ring beam joints, etc. These joints require a large amount of on-site reinforcement work, a high degree of wet work, and the lower part requires A large number of erected formwork supports are not conducive to the application of prefabricated construction; and the concrete pouring in the joint area is also difficult to guarantee the quality due to the restrictions of the working surface and the working environment, and the strength of the joint area will be affected to varying degrees
