I-BEAM SEGMENT CONSTRUCTION BRIDGE CONNECTION METHOD WHICH INCREASED IN JUNCTION STIFFNESS

摘要

A method for connecting I-beam segments of a temporary bridge with improved stiffness in a connection is provided to keep stiffness in a connection of the existing I-beam segments, to prevent a deck plate put on an upper flange of I-beam segments of a temporary bridge from projecting to a connection of I-beam segments and to keep at a level, and to prevent I-beam segments from being damaged when disconnecting I-beam segments of a temporary bridge. A method for connecting I-beam segments(10) of a temporary bridge(B) with improved stiffness in a connection comprises the steps of welding straight or square steel plates on right and left sides of the top of a web(20) in the vicinity of a connection(16) of the I-beam segments using connecting auxiliary flanges(30b), and adding connecting steel plate(18) on upper and lower sides of the auxiliary flanges and fixing with high tension bolts(32), wherein the auxiliary flange of the straight steel plate is not connected with an upper flange(12) and the auxiliary flange of the square steel plate is connected with the upper flange.
