In particular, the relevant technologies of smart girder yards have developed rapidly in recent years, which has largely guaranteed the quality of girder production and maintenance. The entire process of box girder prefabrication includes: selection and construction of prefabrication sites; design, manufacture and installation of formwork, and steel bar binding; layout of the prestressed system and correct embedding of embedded parts; mixing, conveying and pouring of concrete, and maintenance of concrete; prestressing; grouting and sealing of prestressed ducts; storage, transportation and erection of prefabricated beams.

[0003] For the above-mentioned steel bar binding construction, the steel bar cage is bound and formed on the pre-binding pedestal. It is necessary to bind the bottom plate and web steel bars first, then install the positioning mesh steel bars, insert the rubber extraction rod, and finally bind the top plate steel bars. In the process of web steel bar binding, the following problems mainly exist: First, for prefabricated box girders with larger sizes, their webs are longer, and it is necessary to bind steel bars at multiple positions from bottom to top. Construction workers need to use scaffolding and other equipment to climb frequently, which is labor-intensive, and the disassembly and assembly are cumbersome, and there are also safety hazards. Second, for different prefabricated box girders, the web inclinations are different, and the existing steel bar binding devices are difficult to adapt and adjust, and have low applicability.
