Bridge erection concrete prefabricated assembly joint connecting device and method

HUANG YAN

The invention discloses a bridge erection concrete prefabricated assembly joint connecting device which comprises a plurality of concrete structure prefabricated sections, and a traction mechanism used for automatically pulling the concrete structure prefabricated sections to move is arranged between every two adjacent concrete structure prefabricated sections. Guiding and positioning assemblies are arranged at the ends of the concrete structure prefabricated segments; the traction mechanism comprises a mounting seat which is detachably arranged at the end, close to each other, of the adjacent concrete structure prefabricated segments, mounting frames are arranged at the top of the mounting seat, and a hydraulic cylinder body is arranged on one mounting frame. According to the bridge erection concrete prefabrication assembly joint connecting device, the arranged traction mechanism is composed of a hydraulic cylinder body, a steel strand and the like, automatic assembly connection between two concrete structure prefabricated sections can be achieved, pre-positioning between the adjacent concrete structure prefabricated sections is facilitated through cooperation of a positioning plate with the conical end and a positioning groove, and the construction efficiency is improved. And automatic repair of deviation can be realized in the splicing and connecting process.
