Compared with the traditional concrete structure, the steel structure and the mixed structure have the advantages of high construction speed, light dead weight, small rod section and the like, and are widely adopted by modern buildings. In the building design, in order to control the cost, basement buildings generally adopt a concrete structure, and overground parts adopt a steel structure or a mixed structure system in order to meet the requirements of structural earthquake resistance and building attractiveness. This presents a problem in connection of steel members with concrete members.
In the current design and construction process, the steel and concrete connection node is always a difficult point in the project implementation process. The existing graph centralizes two methods of directly penetrating the rib and arranging the bearing pin for the part of the node. The two connection methods can meet the arrangement requirement of the structural steel bars or a small amount of stressed steel bars, but when the number of the steel bars is large, the conventional method for connecting the graph set nodes cannot meet the actual engineering requirement. Therefore, the method for manufacturing the concrete ring beam is provided in the design standard of the building steel structure, and although the method effectively solves the problem of steel bar anchoring, the method for opening the hole at the column edge is not suitable.
Accordingly, there is a need for new techniques and methods to at least partially address the problems of the prior art.
