摘要： PROBLEM TO BE SOLVED: To reduce weight of an upper structure, restrain shear fracture, secure high tenacity performance, and eliminate an underground beam by fixing a concrete-filled steel pipe column to a synthetic steel pipe pile integrally formed on a cast-in-place pile, and installing a girder having a hollow cross section or an opening cross section. SOLUTION: A lower part of a concrete-filled steel pipe column (CFT column) 3 of a railway elevated bridge is fixed to a synthetic steel pipe pile 2 integrally formed in an upper part of a cast-in-place pile 1. A reinforce concrete girder (a hollow girder) 4 having a hollow cross section or an opening close section as a vertical girder member is installed between concrete-filled steel pipe columns 3, 3 adjacent in the bridge shaft direction. A reinforced concrete girder 5 as a horizontal girder member is arranged between the concrete-filled steel pipe columns 3, 3 adjacent in the right-angled direction to the bridge girder direction to be connected to the reinforced concrete girder 4. Thus, earthquake resistant performance to a large-scale earthquake can be secured, a bridge shaft directional span interval L can be set long, and since an underground beam can be eliminated, a construction period is shortened, a construction cost can be reduced, just above elevating work can be realized, and an elevation under space can be effectively used.

摘要： PURPOSE: To reduce the construction term and construction cost greatly and reduce work at an elevated place greatly when a bridge having high bridge pier is constructed. CONSTITUTION: After a bridge pier 2 is constructed by a jack-up construction method at an installation position of the bridge pier 2, a bridge beam of which a central part is supported on the bridge pier 2 is assembled in the vertical direction along the bridge pier 2 by the jack-up construction method by using the bridge pier 2. The thus assembled bridge beam 3 is rotated by using a winch and a wire rope with an upper section of the bridge pier as a support point to construct it in the horizontal direction.
