Embodiment Construction
[0027] The present invention will be described in detail below in combination with specific embodiments.
[0028] The present invention relates to a prefabricated and erected simply supported beam prefabricated channel steel widening structure between tunnels, which can be prefabricated and preassembled in the beam yard, and can be disassembled and transported in place by a beam transport vehicle or an integrated machine for transport and frame erection. Connect and pour the later cast-in-place vertical walls, etc. It can greatly simplify the on-site construction process and effectively shorten the construction period, and has obvious economic benefits.
[0029] The present invention makes the prefabricated box girder 1 transition from the original standard beam width of 12.6m to the prefabricated box girder beam width of 12.1m, and the prefabricated channel steel member 2 is arranged outside the flange end face of the prefabricated box girder 1, and the prefabricated channel ...
