AI Technical Summary
The existing rebar jigs used for large box girders in high-speed railways are inefficient during disassembly, as they cannot be quickly pulled out of the rebar cage, affecting preparations for the next rebar binding.
A common steel reinforcement jig for the inner formwork of a high-speed railway box girder is designed. It adopts a combination structure of U-shaped jig frame, inner support frame, flat support plate, diagonal tie rod and hydraulic rod. The flat support plate is driven to flip and cover the bottom steel reinforcement of the box girder by a jacking mechanism. The inner support frame can be easily removed after the hydraulic rod is detached from the steel reinforcement.
This improved the dismantling efficiency of the rebar cage, facilitated its use in subsequent rebar tying, and enhanced construction efficiency.
