And meanwhile, the horizontal connecting steel plates are all tightly welded with the beam end steel plate. The upper horizontal connecting steel plate and the lower horizontal connecting steel plate are respectively one, the number of the middle horizontal connecting steel plates is determined according to design, and the upper horizontal connecting steel plate and the lower horizontal connecting steel plate are arranged in parallel.
