Rigidity-adjustable steel beam connecting joint

ZHANG YUEGUO / ZHOU PENGFEI / LI MENG

The rigidity-adjustable steel beam connecting joint comprises a steel column (1), a short steel beam (2) and a splicing steel beam (3), the outer side of the short steel column (1) is connected with the short steel beam (2) in a welded mode, and an inner-layer flange plate and an outer-layer flange plate are arranged on the upper portion and the lower portion of the steel beam at the connecting joint of the short steel beam (2) and the splicing steel beam (3). An outer-layer flange plate (10) is connected with a first connecting plate (5) on the inner side of the outer-layer flange plate through a first connecting piece (4) on the outer side of the outer-layer flange plate, an inner-layer flange plate (11) is connected through a second connecting plate (6), and the short steel beams (2) are connected with webs of the splicing steel beams (3) through web connecting plates (7). The outer-layer flange plate (10), the first connecting piece (4), the first connecting plate (5), the inner-layer flange plate (11), the second connecting plate (6) and the web connecting plate (7) are provided with standard bolt holes and connected through high-strength bolts. The rigidity-adjustable steel beam connecting joint has the advantages of being high in connecting strength, convenient to disassemble and wide in application range.
