PROBLEM TO BE SOLVED: To achieve better physical relationship between rubber supports and bridge girders after completion of bridge construction. SOLUTION: It is possible to predict the direction of deviation (direction of displacement) and amount of deviation (amount of displacement) of fulcrum positions of rubber supports 14-1-14-6 when construction of bridge girders 20 is completed by adding up amounts of extension and contraction D1-D5 per span closing time of the bridge girders 20(K1)-20(K5) sequentially. Consequently, each rubber support 14 is sheared and deformed onto a reverse side to the inferred direction of deviation of the fulcrum positions by only the inferred amount of deviation in advance to connect with the bridge girders 20 and adjust their positions, to reduce an amount of deformation of the rubber support 14 at the reference temperature time.
