s1, establishing a steel structure pre-assembled integral model according to the design data, and then performing pre-assembly operation on the steel structure through the integral model;
s2, during pre-splicing operation, the positioning frame plate (1) is sleeved to a spliced steel structure node, then the limiting ring sleeve (3) is pushed to slide through the matching of a limiting block (301) fixedly installed on the outer side and a positioning ring groove (401), the positioning shaft rod (5) and a positioning clamping piece (7) rotatably installed at the end part are subjected to position adjustment until the two positioning shaft rods (5) on the side surface of the positioning frame plate (1) are respectively positioned at the spliced steel structure, then the positioning shaft rods are sleeved to the end part of the positioning shaft rod (5) through a wrench tool, the positioning ring frame (6) can be pushed to the inside of the ring groove (302) through pushing while being sleeved, then the positioning shaft rod (5) is fastened through rotating, and the positioning clamping piece (7) at the end part can be fixed with a corresponding steel structure through the matching of the positioning frame plate (1) respectively when being fastened, after positioning is finished, the two rectangular plates (11) are pushed to rotate along the corresponding outer shaft sleeves (1002) until positioning pieces (1102) at the end parts of the rectangular plates are attached to the corresponding side surfaces of the steel structure, so that the angle between the two rectangular plates (11) is kept fixed;
and S3, after splicing operation is finished, measuring the length and width of the spliced model, the joint gap length of the joint plate and the angle value through a measuring tool, comparing the measured value with the built pre-assembled model, correcting the node exceeding the deviation or replacing the unqualified steel structure until the deviation is met, and recording the deviation value to finish pre-assembling.
