[0002] Steel structure building is a new type of building system that breaks down the industry boundaries between the real estate industry, construction industry, and metallurgical industry, integrating them into a new industrial system. This is the steel structure building system that is generally favored by industry insiders.

[0003] At present, compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. In addition, since the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Since steel can be reused, it can greatly reduce construction waste and is more environmentally friendly. Therefore, it is widely adopted by countries around the world and used in industrial and civil buildings. In steel structure buildings, the main structure of the building is generally composed of steel columns and steel beams.

[0004] In the related art, since the dead weight of steel columns and steel beams is generally large, when connecting steel beams to steel columns, it is often necessary to use lifting equipment, such as a crane, etc., first hang the steel beam above the steel column and overlap it with the steel column, and then pre-fix the steel beam to prevent it from shifting, and then the steel beam and steel column can be connected. However, during pre-fixing, due to the large weight of the steel beam, it is often necessary for personnel and equipment of multiple types to cooperate, and the lifting equipment cannot leave the site until the connection operation is completed. This results in a large amount of manpower and physical effort required to connect a single steel beam to a steel column, and the operation is cumbersome, which seriously affects work efficiency.

The connection structure of steel columns and steel beams of a steel structure building according to claim 4, characterized in that: A locking screw (57) is screwed and connected to the axis of one end of the adjusting shaft (55), the locking screw (57) is threadedly matched with the adjusting shaft (55), and one end of the locking screw (57) is in contact with the screw rod (56).

8. The connection structure of steel columns and steel beams of a steel structure building according to claim 4, characterized in that: A rocker arm (58) is fixed to one end of the screw rod (56) away from the docking rod (54).

9. The connection structure of steel columns and steel beams of a steel structure building according to claim 2, characterized in that: The inner wall of the transmission sleeve (45) is embedded and rotatably connected to a ball (6), and the ball (6) abuts against the steel column (1).

10. A connection method, applied to a connection structure of a steel column and a steel beam of a steel structure building according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, placing the steel beam, first placing the steel beam (2) on the top of the steel column (1) through an external suspension device, and making the steel beam (2) located between the first abutment plate (33) and the second abutment plate (35); S2, active adjustment, rotating the screw (56) to make it interlock with the inner thread of the adjusting shaft (55), thereby driving the adjusting plate (53) to rotate, and the rotation of the adjusting plate (53) drives the interlocking plate (52) to interlock, thereby pulling the transmission sleeve (45) to slide on the steel column (1); S3, driven adjustment, when the transmission sleeve (45) slides, the transmission sleeve (45) synchronously drives the transmission plate (46) to perform linkage, and pulls the pin (44) through the transmission plate (46); S4. The steel beam is pre-fixed. When the pin shaft (44) is in linkage, the pin shaft (44) drives the driven push plate (41) and the active push plate (42) to be linked as a whole, and pushes the second connecting sleeve (34) to slide on the cross bar (31), thereby causing the first abutting plate (33) to abut against the steel beam (2), and pushing the other side of the steel beam (2) to abut against the second abutting plate (35), so that the steel beam (2) is pre-fixed.
