The hanging basket cantilever pouring method is widely applied to construction of large-span continuous beam bridges, the hanging basket is a hanging device used for high-altitude operation, and a hanging structure for hanging basket connection is an important bearing component for hanging a lower steel tray, a bottom die, an outer die, an inner sliding beam, an outer sliding beam and the like. The traditional process takes the finish rolling deformed steel bar as a hanging basket hanging structure, but under the conditions that the finish rolling deformed steel bar is changed in material quality of the finish rolling deformed steel bar by shaking and spark generated by bridge welding operation, and the like, the finish rolling deformed steel bar is easy to break to cause safety accidents, and related departments already prohibit the finish rolling deformed steel bar from being taken as a main hanging rod of the hanging basket at present, so that the steel hanging belt with better stress performance is required to be changed.

The steel suspender is a thick steel plate with holes arranged at certain intervals, and the steel suspender transversely crosses the bolt in the holes and is placed on the steel structure to bear the weight. The bolts penetrate through the hanging strip holes at different positions to adjust the elevation of the lower steel structure and the template, thereby meeting the construction requirement. The finish rolling deformed steel bar is more suitable for pure vertical tension, and the safety of the steel hanging strip is far higher than that of the finish rolling deformed steel bar during construction: firstly, the sectional area of the steel sling is far larger than that of finish rolling deformed steel bars, and because the pure vertical tension force is static in the construction condition of the basket, the steel sling has various uncertain factors such as uneven load shaking, high-altitude wind load-induced swinging and the like, and the bearing capacity of the steel sling is suitable for various adverse working conditions.

However, the holes of the steel slings have a certain interval, so the elevation cannot be continuously and accurately adjusted. The method of filling steel plates under the support cross beams after the jack is jacked is adopted in a construction site, and the steel plates with different thicknesses are used for filling for multiple times so as to achieve more accurate elevation.

The application patent CN 111021259A discloses a micro-adjusting device for realizing elevation lifting precision of a hanging basket hanging belt for bridge construction, which comprises a cross beam, a through hole arranged in the cross beam, a clamping seat arranged in the through hole and a fine-adjusting structure arranged in the through hole and used for controlling the clamping seat to move. The beam and the clamping seat are separated, the beam and the clamping seat can move relatively, the clamping seat is used for supporting the pin shaft, the clamping seat is adjusted and controlled to move through the fine adjustment structure so as to adjust the height of the clamping seat, fine adjustment is achieved, the purpose of accurately controlling elevation is achieved, elevation control is achieved through the structure, and complex and potential safety hazards caused by repeated replacement of base plates with unequal thicknesses can be avoided. But in the working process, a plurality of nuts are required to be adjusted simultaneously, the operation is inconvenient, only the lower end is fixed, the upper end is unconstrained between the clamping seat and the fine adjustment structure, the stability is poor, and the safety of the construction process cannot be guaranteed.
