Description

Technical Field

[0001] This utility model relates to the field of structural engineering technology, specifically to a rigid joint structure between a concrete column and a steel beam. Background Technology

[0002] Due to its numerous advantages, including lightweight, high strength, good plasticity and toughness, fast construction speed, and aesthetic appeal, steel structure construction has experienced rapid development and is increasingly used in industrial and civil buildings. In newly built factories and large-span stadiums, as well as in the expansion and addition of floors in renovation projects, there is a growing trend of connections between steel and concrete structures, such as the connection between steel beams and concrete columns. These connections are mostly made using chemical anchors or expansion bolts. The stiffness of the connection between the steel beam and concrete column joints is closely related to the stability of the structure and has a significant impact on the internal forces and displacements. While ensuring the safety and reliability of the joint, it can transfer the bending moment and shear force generated by the beam to the concrete column. Based on whether it can transfer bending moment, the connection method can be divided into hinged connections and rigid connections.

[0003] Currently, in the design of steel structures for industrial and civil buildings in my country, the rigid connection between concrete columns and steel beams mainly relies on chemical anchors or expansion bolts to fix the end plates of the steel beams to the concrete columns. The connecting plates extending from the end plates and the webs of the steel beams are connected by high-strength bolts, and the beveled edges of the upper and lower flanges of the steel beams and the end plates are connected by butt welds.

[0004] In the use of existing rigid joints between concrete columns and steel beams, the steel beams are mostly fixed to the concrete columns using anchor bolts or expansion bolts. After long-term corrosion, the anchor bolts or expansion bolts will be damaged, making it easy for the connection between the expansion bolts or chemical anchors and the concrete column at the joint to loosen. At the same time, the joint structure will bend, making it difficult for the joint structure to achieve a real rigid connection. Utility Model Content

Movable plates are provided at both ends of the fixed plate, and one side of the fixed plate is in contact with one side of the concrete column body. Fixed seats are symmetrically provided at both ends of the mounting plate, and threaded rods are provided on the fixed seats. One end of the threaded rod is provided with an adjustment block two, and the movable plate is connected to the threaded rod.

[0012] Furthermore, in order to better ensure the connection and fixation effect of the steel beam body, the second connection component includes four movable seats.
