METHOD FOR MANUFACTURING OF STEEL GIRDER COUPLED WITH PRECAST-CONCRETE PARTS ON UPPER FLANGE OF STEEL GIRDER

摘要

A method of making a steel composite girder in which a precast concrete member is joined to a steel girder upper flange is disclosed. A method for manufacturing a composite composite girder in which a precast concrete member is combined with an upper flange of a steel girder according to the present invention is a method for manufacturing a composite composite girder having an I shape or a U shape having an upper flange (12), a belly portion (14) Sectional girder (10) having a cross-section, combining the segmented steel girder with a single steel girder and connecting the upper end flange (12) of the joined steel girder with a shear connection (20) (2) a step of inserting the support support (30), and the combined steel girder is moved from both ends to L (combined steel girder length) / 4 to L (combined steel girder length) A precast concrete member 40 having an opening 42 formed therein for inserting a front end connection member 20 provided on the upper flange 12; Prize (40) to the openings (42) and the connecting portions (44) of the precast concrete member, and the unfired concrete having a compressive strength not lower than the compressive strength of the precast concrete member And integrating the combined steel girder and the precast concrete member 40 and moving the mounting support 30 to both ends of the combined steel girder.
