PROBLEM TO BE SOLVED: To provide a method for constructing an arch rib of a concrete arch bridge, by which the construction can be rationalized when constructing the arch rib of the concrete arch bridge. SOLUTION: In the Meran (steel arch) construction method, wherein the arch rib 10 is formed by constructing a Meran material 11 between a pair of erected parts 13 which are overhung from both the ends of the arch rib and concrete is placed in the Meran material 11 so as to construct a Meran erection part 12, a steel panel 20 includes a main beam 21 of T-shaped steel with a projection arranged side by side, a bottom steel plate 22 attached below the main beam 21 and a side steel plate 23 attached to a width end portion of the bottom steel plate 22, and is erected in an arch shaped to be used as the Meran material 11. Furthermore, concrete 26 is placed into a part of a flange and a web of the main beam 21 of the Meran material (steel panel) 20 to construct the Meran erection part 28. COPYRIGHT: (C)2010,JPO&INPIT
