[0002] With the increasingly tense urban land resources and the continuous increase in building height, in order to effectively control the cross-sectional size of the bottom frame columns of buildings and improve the structural efficiency, steel sections are ingeniously placed inside the cross-section to form concrete-filled steel tube columns with both strength and stiffness. However, in the pursuit of the balance between economic benefits and technical feasibility, the floor system mostly adopts the mature and economical reinforced concrete structure. In the combination of concrete-filled steel tube columns and reinforced concrete beams, the connection structure between the concrete-filled steel tube columns and the reinforced concrete beams has become the top priority of construction quality control.
[0003] The traditional connection structure between a concrete-filled steel tube column and a reinforced concrete beam usually uses a combination of a fixing plate and bolts for connection and fixation. This connection method restricts the high bearing capacity potential of the concrete-filled steel tube to a certain extent. When in long-term service or facing large load challenges, stress concentration is likely to occur in the connection area, which may then induce surface cracks, having a non-negligible impact on the safety and durability of the overall structure.
[0004] For the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0012] Furthermore, in order to improve the safety and durability of the overall structure, the adjustment component includes a plurality of groups of limit grooves opened at one end of the fixed plate.
[0013] Furthermore, in order to achieve the positioning of the crossbeam steel bars and reduce the steel bar positioning errors caused by manual operation errors or construction environment limitations, the adjustment component also includes several groups of limit grooves 2 opened at one end of the fixed plate 2, the limit grooves 1 and 2 are matched with each other through the limit plate, and a limit hole matching the crossbeam steel bars is opened on one side of the limit plate.
