When the common reinforced concrete column can not meet the requirement, a plurality of projects adopt the steel reinforced concrete column (called steel reinforced column for short), and the steel ribs arranged in the column are usually in a cross shape and are formed by vertically intersecting two I-shaped steel in the form. Because the steel ribs are arranged in the columns, the connection between the main ribs in the beam and the columns is hindered, and the stress performance of the joints is influenced. The common practice in the current engineering is as follows: the beam main rib blocked by the cross steel rib flange in the column is connected with the flange; the opening in the web of the steel column passes through the opening which is not blocked by the flange of the steel column.
In order to enable the main beam reinforcements to penetrate through the column steel rib web, a steel structure factory needs to fully understand the design condition of the beam reinforcements and consider the actual on-site placement condition when processing steel ribs, and then a quasi-open hole position can be reserved; during on-site construction, steel bars need to be placed according to hole sites of detailed steel structure processing.
