firstly, a short bracket and a beam longitudinal steel bar welding mode which cannot be communicated are arranged on a profile steel flange plate in a column.
And secondly, a short steel beam and a beam longitudinal steel bar lap joint mode are arranged on the profile steel flange plate in the column.
And thirdly, arranging a steel sleeve connector on the profile steel flange plate in the column to be connected with the beam longitudinal steel bars which cannot be communicated.
Fourthly, holes are formed in the column medium-sized steel web plate, and the beam longitudinal ribs are connected in a penetrating mode by bypassing the column-shaped steel flange.
When the steel reinforced concrete structure is specifically constructed, main steel components in the connection node structure of the center pillar and the concrete beam of the steel reinforced concrete structure need to be processed and manufactured in a factory in advance, and then are installed on site, so that the welding workload on the site is reduced as much as possible to ensure the engineering quality.
