In this invention, the joint between the column and the beam is provided so as to protrude integrally from the precast reinforced concrete column to the beam end position, so the rigidity of the frame can be increased, thereby making it possible to increase the span.
In addition, sufficient joint strength can be expected as the joints and beam steel frames are tightened with cover plates attached to the top and bottom surfaces of the joints using prestressed steel rods passed through the joints. In addition, the processing of the steel beam only involves drilling bolt holes, which saves processing time, and the length of the steel beam can be shortened by the length of the joint, which can lead to cost reductions. Furthermore, this construction method allows for a significant reduction in construction time.
