The inner partitions at the connection nodes with the H-shaped steel beam are welded in the processing plant. After the nodes are transported to the construction site, the beams and columns are connected by bolting or welding.

[0042] Working principle: After the crossbeam 9 is inserted into the connecting sleeve 4, the second knob 12 is rotated so that the second knob 12 drives the second screw rod 10 to rotate and perform a threading action with the second screw sleeve 11. When the second screw sleeve 11 penetrates the crossbeam 9 and enters the lower end of the connecting sleeve 4, the position of the crossbeam 9 is fixed. When it is necessary to adjust the height of the connecting sleeve 4 on the square column 1, the first knob 7 can be rotated first so that the first knob 7 drives the first screw rod 5 to rotate and perform a threading action with the first screw sleeve 6. After the first screw 5 rotates out of the rotating hole 8, the sleeve rod 15 can be rotated so that the sleeve rod 15 drives the third screw sleeve 18 to rotate and The third screw 17 is threadedly acted on the third screw 17, so that the third screw 17 moves inside the movable groove 16. As the length of the third screw 17 changes, it will push the crossbeam 9 to drive the connecting sleeve 4 to follow the slider 3 to slide in the slide groove 2. When the connecting sleeve 4 moves to a suitable position, the first knob 7 can be rotated again, so that the first knob 7 drives the first screw 5 to rotate and is threadedly acted on the first screw sleeve 6.
