Mounting structure of Steel Cross-beam in Multi-girder concrete bridge and its construction method

摘要

The subject innovation is PS's (PSC; Prestressed concrete) beams such as the concrete is the concrete in the application water is to increase the ease and safety using a steel cross beam in the mold bridge of the mold bridge steel on the robotic installation structure and its method of construction of the as, steel cross beam was produced by embedding the anchor for installation at the beam at the time of said beam produced PS and connected to the end of the production of the beam by using the high-strength bolts for the connecting member to the buried anchor, using the crane PS's beam on the piers installation and 2, for when the beam is installed, the steel material is to salvage the Robo between beam through to high-strength bolt wherein when the installation error occurred dies and Shore from, high-rise by ever construction to correct the error using the slot of the connecting member working this reinforced the welding operation is unnecessary, and no need for such anti-tip ball of the beams improves the workability and safety, ball Based economy is also reduced, as well as have the effects that can be improved.
