[0053] In addition, the positioning and clamping assembly 52 includes:

[0066] Construction principle and steps:

[0067] S1: Installation of the cantilever beam 3. The cantilever beam 3 is hoisted to the height position of the connecting beam 2, and then one end of the cantilever beam 3 is translated to the positioning clamping assembly 52 for clamping;

[0068] S2. Clamping of the cantilever beam 3. When the cantilever beam 3 moves to the position of the positioning clamping assembly 52, the moving motor 534 drives the screw rod 533 to rotate, so as to drive the slider 532 to move at the outer end of the slide rail, so that the positioning clamping assembly 52 moves outward to between the two ends of the cantilever beam 3 and the two sets of clamping arms 522. Then the power member works to drive the clamping arms 522 to move, and the rotation clamping of one end of the cantilever beam 3 is realized through the setting of the rotating disk 523 thereon;

[0069] S3. Angle adjustment of the cantilever beam 3. After the cantilever beam 3 is rotationally clamped, the rotation motor 536 operates, driving the positioning clamping assembly 52 to rotate through the rotating shaft 535, so as to realize the angle adjustment of the cantilever beam 3 during hoisting. Then, the moving motor 534 operates to drag the positioning clamping assembly 52 back to dock the cantilever beam 3 and the connecting beam 2;

[0070] S4. Support of the cantilever beam 3. After one end of the cantilever beam 3 is docked with the connecting beam 2, the winding motor 65 drives the winding drum 62 to rotate, realizing the rope-laying operation of the lifting rope 63 until the hook 64 is hung on the lifting lug 61 at the end of the cantilever beam 3 away from the connecting beam 2. Then, the lifting rope 63 is wound up to make the lifting rope 63 taut. Then, by winding and unwinding the lifting rope 63 through the winding drum 62, the vertical angle of the cantilever beam 3 is adjusted to make it perpendicular to the connecting beam 2. Then, the cantilever beam 3 is installed on the connecting beam 2 through fasteners such as bolts;

[0071] S5. Installation of the curved beam. As described above, multiple cantilever beams 3 are successively installed on this section of the connecting beam 2 according to the construction requirements and are supported by the support unit 6. Then, the curved beam body 4 of this section is hoisted to the position of the cantilever beam 3 for docking. Due to the existence of the support unit 6, the cantilever beam 3 can be kept perpendicular to the vertical direction. At the same time, according to multiple cantilever beams 3, the position of the curved beam body 4 can be determined. At the same time, when the cantilever beam 3 is kept perpendicular to the vertical direction, the installation angle of the curved beam body 4 can be prevented from tilting during installation. After the installation of the curved beam body 4 is completed, except for the support units 6 at both ends of this section that are not disassembled, the support units 6 in the middle can be disassembled, so that the curved beam body 4 of this section can always be ensured not to tilt during the cantilever construction, so that the curved beam body 4 of this section can be used as the docking punctuation for the construction of the next section of the curved beam body 4;

[0072] S6. Construction of the next section of the curved beam. Install the cantilever beam 3 and the curved beam as described above. Then, when the support unit 6 is removed, the support units 6 at both ends of these two sections are retained, and the remaining support units 6 can be removed, so that after each section of construction is completed, the constructed curved beam body 4 always remains vertical. When the construction of the curved beam is relatively long, except for the two groups of support units 6 at the ends that are retained, several more groups of support units 6 can be retained.
