[0030] In the installation, the staff needs to align the plug-in part 41 at the bottom of the cross beam 4 with the connecting hook 3 and plug from top to bottom, so that the elastic positioning assembly 5 is plugged and matched with the positioning port 31 on the connecting hook 3, which ensures the quick and stable connection of the cross beam 4 with the base column 1 and the annular connecting seat 2, changes the design mode of connecting by using multiple bolts in the traditional technology, avoids the tedious operation of repeatedly screwing multiple bolts by the staff, improves the connection efficiency between the cross beam 4 and the base column 1, and further improves the construction efficiency of the multi-layer assembly type building.

[0031] The cross beam 4 is a hollow square tube structure, the elastic positioning assembly 5 includes an installation cylinder 51 fixed at a position close to the plug-in part 41 of the cross beam 4, a pressing spring 52 arranged in the installation cylinder 51 and a positioning rod 53 connected with one end of the pressing spring 52 close to the base column 1, the installation cylinder 51 is located at the side of the plug-in part 41 away from the base column 1, and the end of the positioning rod 53 away from the pressing spring 52 is plugged and matched with the positioning port 31.

[0032] In the installation of the cross beam 4, the staff only needs to align the plug-in part 41 at the bottom of the cross beam 4 with the connecting hook 3 and plug from top to bottom, so that the second inclined surface 7 on the positioning rod 53 abuts against the top of the connecting hook 3, so that the positioning rod 53 gradually shrinks into the installation cylinder 51 and compresses the pressing spring 52, when the positioning rod 53 is plugged and matched with the positioning port 31, the positioning rod 53 resets under the action of the pressing spring 52 and is plugged with the positioning port 31, and at this time, the plug-in part 41 at the bottom of the cross beam 4 is plugged with the connecting hook 3 on the side wall of the base column 1, and one end of the cross beam 4 is plugged with the clamping part 21 on the annular connecting seat 2, which realizes the quick and stable connection of the cross beam 4 with the base column 1 and the annular connecting seat 2.

[0033] The beam 4 is provided with a separating mechanism 8, which comprises a separating assembly 81, the separating assembly 81 comprising a vertical rod 811 rotatably installed in the beam 4, a pulley 812 fixedly sleeved on the vertical rod 811, a horizontal plate 813 fixed to the inner wall of the beam 4, a winding roller 814 rotatably installed on the bottom wall of the beam 4, a movable plate 815 arranged in the beam 4, a pressing block 816 fixed to the top of the movable plate 815, a traction rope 817 with one end fixed to the winding roller 814, and a first spring 818 sleeved on the vertical rod 811 and arranged between the bottom of the movable plate 815 and the top of the horizontal plate 813; the vertical rod 811 penetrates through the movable plate 815 and the horizontal plate 813 and is in sliding fit, the top of the beam 4 is provided with a pressing opening 42 through which the pressing block 816 passes, the end of the traction rope 817 away from the winding roller 814 passes through the pulley 812 and the mounting cylinder 51 and is fixed to the end of the positioning rod 53 away from the base column 1, and the separating mechanism 8 further comprises a transmission assembly 82 for driving the winding roller 814 to rotate in the process of the descending of the pressing block 816.

[0034] When the beam 4 needs to be disassembled, the worker only needs to press down the pressing block 816, the pressing block 816 drives the winding roller 814 to rotate through the transmission assembly 82, so that the end of the traction rope 817 away from the positioning rod 53 is gradually wound on the winding roller 814, thereby causing the traction rope 817 to pull the positioning rod 53 and causing the compression of the compression spring 52, until the positioning rod 53 is separated from the positioning opening 31, at this time, the worker can lift up the beam 4 and separate the beam 4 from the annular connecting seat 2 and the connecting hook 3, thereby completing the disassembly of the beam 4.
