Further, the adjustable disc-shaped lifting appliance 2 is utilized to realize integral lifting of the large-diameter variable-circular-section steel bar segment steel bar, and the concrete method is as follows:
s1, binding the steel bar segments according to a preset rounded section profile.
The binding of the steel bar segments is generally configured at the binding platform, the positioning part of the bottom opening of the steel bar segments of the binding platform is provided with a prefabricated positioning toothed plate, and the positioning toothed plate is cut in a numerical control mode so as to meet the butt joint requirements of the top opening and the bottom opening of each steel bar segment, and particularly the gradient requirement of the main bar during binding.

S2, setting lifting points and connecting corresponding lifting appliances according to the deformation condition of the lifted reinforcing steel bar segments.
According to calculation, the large-diameter round section steel bar segment is lifted in a conventional manner, the self weight of the large-diameter round section steel bar segment can cause the deformation of the first main bar 11 of the round section to be increased, and the deformation is different from that of the conventional case, so that the lifting stability of the round section is required to be increased, the deformation after lifting is controlled, one control mode is to increase the lifting points, and the other control mode is to increase the lifting area of a single lifting point. In addition, for the outer ring structure 1a with dense main ribs in the embodiment of the present application, a denser tensile force needs to be set to control the deformation amount. Therefore, with the aforementioned adjustable disc-shaped hanger 2, hanging points are set for the steel bar segments according to the predicted deformation condition of the large-diameter rounded section, specifically, the positions of the connecting movable hangers 24 are determined on the steel bar segments, the first movable hangers 24a with a large number of primary reinforcements are uniformly fixed on the outer ring structure 1a of the steel bar segments, the second movable hangers 24b with a small number of primary reinforcements are uniformly fixed on the inner ring structure 1b of the steel bar segments, the relative heights of the movable hangers 24 need to be adaptively adjusted, and the relative heights are mainly determined by the lengths of the rope rings 245 and the lengths of the adjustable connectors, so that all hanging points are not coplanar under most conditions. However, it will be appreciated by those skilled in the art that when lifting segments of steel bar of circular cross-section (or other centrosymmetric cross-section) using the adjustable dish-shaped lifting appliance 2 of the present application, the lifting points should be set as required for lifting, and that the lifting points may be coplanar.
S3, integrally hoisting the steel bar segments to a butt joint position by utilizing the lifting appliance;
the overhead hoisting posture leveling is carried out before the whole hoisting of the steel bar segments, namely, the steel bar segments are lifted to be about 10cm away from the binding platform, the inclination of the steel bar segments is observed, and the leveling is carried out by utilizing an adjustable connecting piece at the moment, specifically, the flower basket screw rod is matched with the chain block to level the steel bar segments. And after the preliminary leveling is finished, continuously lifting the steel bar segments, and lifting the steel bar segments to the upper part of the butt joint position in a gradual lifting and translation mode so as to prepare for alignment connection. In practice, the segments of rebar are not guaranteed to be completely undeformed when in the air, but can be subsequently butted using their controlled deformation.
S4, after the first main rib 11 at the arc section is abutted, unloading the lifting appliance for the first time; after abutting the second main bar 12 at the straight section, the spreader is withdrawn.
During butt joint, the bottom opening of the current steel bar segment is in butt joint with the top opening of the bottom-section steel bar segment, namely the main bar connection of the upper steel bar segment and the lower steel bar segment is completed. When the large-diameter round section steel bar segment is installed, the first main rib 11 of the circular arc segment with smaller controlled deformation amplitude is connected when the steel bar segment is lifted in place, then the lifting equipment is used for unloading most of the lifting weight, the unloading load can be 60% -85% of the total load, namely, the partial weight of the actual steel bar segment is transferred to the constructed segment by the lifting equipment, after the supporting state of the steel bar segment is changed, the whole shape of the steel bar segment is restored to be closer to the actual connection state, namely, the second main rib 12 at the straight line segment with larger controlled deformation amplitude is restored to the assembly state by the inward-tilting or outward-stretching deformation reduction when the steel bar segment is lifted, so that the connection of the upper steel bar segment and the lower steel bar segment is facilitated. And after abutting the second main rib at the straight line section, withdrawing the lifting appliance. After the lifting appliance is removed, binding of the residual steel bars of the steel bar segments is completed, and therefore the whole lifting procedure of the steel bar segments is completed.
