[0002] In steel structure buildings, H-shaped steel and H-shaped cantilever rods are common support structures. The connection between H-shaped steel and H-shaped cantilever rods mostly uses angle steel and bolts for connection, resulting in poor anti-deformation ability between the H-shaped steel and the H-shaped cantilever rod. Therefore, we designed a connection structure between an H-shaped steel and an H-shaped cantilever rod. By using an expanded U-shaped plate to reinforce at the connection, the connection strength between the H-shaped steel and the H-shaped cantilever rod is strengthened, and the anti-deformation ability at the connection is increased.

The web of the H-shaped cantilever is inserted between the two connecting plates. The flange of the H-shaped cantilever abuts against the connecting plates. The web of the H-shaped cantilever and the two connecting plates are connected by two bolts II. Rib plates are welded to the opposite sides of the two connecting plates. Four bolts III pass through the two flanges of the H-shaped cantilever and the two rib plates. Two symmetric expansion type inner support assemblies are arranged on the side close to the connecting plates between the two flanges of the H-shaped cantilever. The expansion type inner support assembly includes an L-shaped plate I and an L-shaped plate II. A rectangular through hole is opened on one side of the L-shaped plate I. A screw rod is rotatably connected to the inner cavity of the rectangular through hole. One end of the screw rod penetrates to the outside of the L-shaped plate I. The L-shaped plate II is threadedly connected to the surface of the screw rod. The bolt III passes through the L-shaped plate I and the L-shaped plate II.

[0005] Preferably, the side of the rib plate close to the mounting plate is welded to the mounting plate.
