[0002] A cable-stayed bridge is a special type of bridge structure. Its main feature is that it uses one or more sets of diagonal cables (cables) to directly connect the bridge deck (main beam) to the bridge tower (cable tower), forming an efficient load-bearing system. During the construction of a cable-stayed bridge, the steel bar binding of the main pier tower column is a critical and complex construction process, which directly affects the bearing capacity and durability of the tower column structure.

[0003] At present, in the process of steel bar binding of the main pier tower column of the cable-stayed bridge, due to the complex geometric shape of the tower column structure (such as curved profile, non-rectangular cross-section), coupled with special load-bearing requirements and unconventional spatial layout, the traditional scaffolding or hanging basket system may be difficult to directly adapt to these characteristics. This causes construction workers to encounter many difficulties when dealing with the steel bar binding work in certain complex structural areas in the tower column. For example, the construction workers need to perform delicate operations in a limited operating space, which increases the complexity and technical difficulty of the binding process. In addition, the construction workers cannot flexibly adjust the working position, resulting in limited working space and affecting work efficiency. Utility Model Content

The positioning rod 6 is inserted into the positioning tube 7, and the inner end of the horizontal part of the suspension frame 1 is also welded and fixed with a fixing frame 18. The two suspension frames 1 of this structure can be moved by hanging the hook part 2 on the steel bar, and the positioning frame 3 is used to move between the horizontal parts of the two suspension frames 1 to drive the bracket 4 to shift as a whole. When the bracket 4 shifts, the positioning rod 6 can be driven by the outer frame 5 to slide inside the positioning tube 7 for limited fixation. In this way, the bracket 4, the outer frame 5 and the fixing frame 18 can form a platform for construction workers to stand between the horizontal parts of the two suspension frames 1, so that the construction workers can tie the steel bars of the main pier tower column of the cable-stayed bridge, which solves the problem of difficult steel bar tying work on the main pier tower column of the cable-stayed bridge. In addition, this platform structure has the advantages of simple structure, high operability and space saving. The hook part 2 has the advantages of small space and high adjustability, which is conducive to improving the work efficiency of construction workers during operation. A solid block 11 welded and fixed on the suspension frame 1 is provided at the opening of the hook part 2, and a stopper 13 is movably provided on the outer side of the solid block 11. The inner end of the stopper 13 is movably arranged on the outer wall of the top end of the solid block 11 through a pin shaft, and a metal support sheet 12 is connected between the stopper 13 and the solid block 11. The metal support sheet 12 is made of an existing elastic metal material and is provided with a support spring inside. The stopper 13 of this structure can maintain a certain elastic force on the outer side of the solid block 11 under the elastic force of the metal support sheet 12, so that the hook part 2 can be conveniently hung on the steel bar, and the stopper 13 can also limit the hanging of the hook part 2 on the steel bar, ensuring the stability of the hook part 2 when hanging. The positioning rod 6 is located at one end of the positioning tube 7 and is welded and fixed with a protrusion 9, and the outer side of the positioning tube 7 is provided with a transverse opening 8 that matches the protrusion 9, and the outer end of the protrusion 9 extends to the outside of the positioning tube 7 through the transverse opening 8, and the inner side of the outer end of the protrusion 9 is inserted with a fixing pin 14 through a threaded structure, and a support strip 15 is welded and fixed to the bottom of the positioning tube 7, and the top of the support strip 15 is evenly provided with a number of positioning holes that match the bottom end structure of the fixing pin 14. When the positioning rod 6 of this structure slides inside the positioning tube 7, it will simultaneously drive the protrusion 9 to slide transversely on the transverse opening 8 until the positioning rod 6 extends to a suitable length on the positioning tube 7. The fixing pin 14 can be rotated at the outer end of the protrusion 9 to make the bottom end turn into the corresponding positioning hole on the top of the support strip 15.After the fixing pin 14 is limited, the extension length of the positioning rod 6 can be locked. After the positioning rod 6 is locked, the bracket 4 and the outer frame 5 are simultaneously limited in the appropriate position. A reinforcing rib 10 is welded between the vertical part and the horizontal part of the suspension frame 1, and the reinforcing rib 10 is obliquely distributed between the vertical part and the horizontal part of the suspension frame 1. The reinforcing rib 10 of this structure can improve the overall stability of the suspension frame 1 and ensure the safety of construction personnel when using it. A guide column 16 is provided on one side corresponding to the horizontal part of the suspension frame 1 through a recess, and a connecting sleeve 17 movable on the outside of the guide column 16 is welded and fixed at both ends of the positioning frame 3. The positioning frame 3 of this structure can drive the connecting sleeve 17 to slide along the outside of the guide column 16 when it is active, so as to improve the stability of the positioning frame 3 when driving the bracket 4 to adjust the overall position.

[0018] Working principle: When using the variable position cable-stayed bridge main tower steel bar binding platform, first, the two suspension frames 1 can be hung on the steel bars by the hook part 2. When the opening of the hook part 2 is in the hanging process, the steel bars will contact the stopper 13. After the stopper 13 is stressed, it will move on the outside of the solid block 11 under the elastic force of the metal support sheet 12 until the steel bars enter the opening of the hook part 2. The stopper 13 will be reset under the elastic force of the metal support sheet 12 to limit the steel bars, and the positioning frame 3 can move between the horizontal parts of the two suspension frames 1 to drive the bracket 4 to shift as a whole. When the positioning frame 3 moves, it can drive the sleeve 17 to slide along the outside of the guide column 16, and when the bracket 4 shifts, it will also drive the positioning frame 3 through the outer frame 5. The positioning rod 6 slides inside the positioning tube 7. When the positioning rod 6 slides inside the positioning tube 7, it will simultaneously drive the boss 9 to slide horizontally on the horizontal opening 8. Until the positioning rod 6 is extended to a suitable length on the positioning tube 7, the fixing pin 14 can be rotated at the outer end of the boss 9 so that the bottom end is turned into the corresponding positioning hole at the top of the support bar 15. After the fixing pin 14 is limited, the extension length of the positioning rod 6 can be locked. After the positioning rod 6 is locked, the bracket 4 and the outer frame 5 are simultaneously limited to the appropriate positions. In this way, the bracket 4, the outer frame 5 and the fixing frame 18 can form a platform for construction workers to stand between the horizontal parts of the two suspension frames 1, so that the construction workers can tie the steel bars of the main pier tower column of the cable-stayed bridge, thereby completing a series of work.
