JOINT STRUCTURE BETWEEN STEEL MAIN GIRDER AND PIER AND JOINT METHOD

PROBLEM TO BE SOLVED: To greatly reduce reinforcements of a rigid connection section between a steel main girder and a pier, enable workability to improve and, at the same time, to provide a joint structure between the steel main girder capable of being rationally designed and the pier and a joint method. SOLUTION: A plurality of cell chambers 13 are formed of oppositely arranged webs and cell steel plates partitioning among these webs, a multi-chamber cell cross beam 10 provided with a slippage stop to both of the web and the cell steel plate or either one of them and a pair of steel girders 1 placed in the direction of the bridge axis on the pier P are included in each cell chamber 13, the multi-chamber cell cross beam 10 is placed between a pair of steel girders 1 to fit the cell chamber 13 to the upper part of a projection attached steel frame 30 burying the lower part in the pier, both end sections thereof are connected to the steel girder 1 to constitute the steel main girder G, and the cell chamber 13 of the multi-chamber cell cross beam 10 is filled with concrete to make the rigid connection between the steel main girder G and the pier P.
