Technical Field
[0001] The utility model belongs to the technical field of steel structure buildings, and particularly relates to a hinged connection structure between a steel beam and a concrete wall. Background Technique
[0002] The application of steel structures in industrial and civil buildings is increasing. In some newly built factories and large-span stadiums, as well as in the expansion and storey-adding construction of some renovation projects, there are more and more connections between steel structures and the original concrete structures, such as the connection between concrete columns and steel columns, the connection between steel columns and concrete beams, and the connection between steel beams and concrete columns. Most of these connections are made through chemical anchor bolts or expansion bolts. Among them, the hinged connection between concrete walls and steel beams often appears in expansion projects.
[0003] A steel plate is installed on the concrete wall through chemical bolts, and a connecting plate for connecting the steel beam is welded on the steel plate. The connection between the connecting plate and the steel beam is realized through multiple bolts. Since the load of the steel beam is large, it is easy to cause tearing on the connecting plate and the steel plate. Therefore, we designed a hinged connection structure between the steel beam and the concrete wall. A support structure is arranged between the bottom of the steel beam and the steel plate, and a pulling structure is arranged above the steel beam, which improves the connection strength and load-bearing capacity of the steel beam, reduces the possibility of fracture between the steel beam and the steel plate, and improves the connection firmness.
