It is made of steel, has high strength and durability, and bears and disperses the load of the building or structure to ensure its stability and safety. Specifically, the long-span steel beam is more and more widely used in super-high-rise civil buildings and some other large buildings. In current technology, various connection auxiliary devices such as hoisting devices, clamps or support mechanisms are required for the connection of long-span steel beams. However, when two long-span steel beams need to be connected based on different connection angles or connection orientations, a set of support mechanisms need to be equipped respectively, and the versatility of the support mechanisms is poor.

[0051] According to one embodiment of the present application, the end of the first articulated sleeve 203 is provided with a first avoidance notch 209 on the side away from the third top support arm 201, and the end of the second articulated sleeve 205 is provided with a second avoidance notch 210 on the side away from the fourth top support arm 202. When the angle between the first top support structure 100 and the second top support structure 200 is 0°, the third top support arm 201 and the fourth top support arm 202 are located between the first top support arm 101 and the second top support arm 102. When the angle between the first supporting structure 100 and the second supporting structure 200 is 180°, the first end of the first supporting arm 101 can be accommodated in the first avoiding notch 209 so that the third supporting arm 201 and the first supporting arm 101 are in the same straight line, and the first end of the second supporting arm 102 can be accommodated in the second avoiding notch 210 so that the fourth supporting arm 202 and the second supporting arm 102 are in the same straight line. Of course, if the first pressing block 107, the second pressing block 108, and the third pressing block 2 07 and the fourth top pressure block 208 can move in a direction parallel to the first axis, and the design of the first avoidance gap 209 and the second avoidance gap 210 can be cancelled.

A corresponding third avoidance gap 211 can also be set on the first articulated sleeve 203, and a corresponding fourth avoidance gap 212 can be set on the second articulated sleeve 205. Based on the avoidance need when the angle between the first top support structure 100 and the second top support structure 200 is 90°, the third avoidance gap 211 and the fourth avoidance gap 212 should both be two arranged in pairs, and the two third avoidance gaps 211 are formed on the same radial direction of the first articulated sleeve 203, and the two fourth avoidance gaps 212 are formed on the same radial direction of the second articulated sleeve 205.

The first locking structure 2, the second locking structure 3, the third locking structure 4, the fourth locking structure 5, the fifth locking structure 6 and the sixth locking structure 7 can specifically adopt a threaded pressure rod with a knob, such as a peripheral wall of the first hinge sleeve 203. A through hole is opened, and the fourth locking structure 5 (a threaded pressure rod with a knob) passes through the through hole of the peripheral wall of an articulated sleeve. After tightening the threaded pressure rod with the knob, the central axis 1 can be pressed so that the first articulated sleeve 203 and the central axis 1 are relatively fixed. After loosening the threaded pressure rod with the knob, the first articulated sleeve 203 and the central axis 1 can move relative to each other. Based on the previous embodiment, if a first avoidance gap 209 and a second avoidance gap 210 are designed, it is necessary to use these avoidance gaps to make the first articulated sleeve 203 and the second articulated sleeve 205 move axially toward the two ends of the central axis 1. When the first locking structure 2 and the second locking structure 3 are laterally mounted threaded pressure rods with knobs, it is preferred that the first locking structure 2 and the second locking structure 3 are arranged on a portion of the central axis 1 between the first articulated sleeve 203 and the second articulated sleeve 205.
