Girder making methos for precast end seggement using end mold and girder therewith

In as produced for bridges PSC beams (girder), both ends since the load due to the fixing device and tendons concentration which free the cast method produced first, and making first the central part is pre-cast method between both ends end segments to the start of the girder production method of manufacturing using the end mold corresponds to the production, first the both ends of the segment of the girder being prestressed is concentrated by the fixing device in the precast end segment using a high-strength concrete, and the girders making the length for this so as to be positioned at both ends of the fabricated girders spaced from each other said precast end segment in the longitudinal direction of the girder, and by setting the center mold between the precast end segment, but making the center segment, mold the central portion is a positive precast end the segment center side girders The outer surface of the section and to match the inner surface of the mold for the center segment having the same cross-sectional shape as the girder center side end face of the end segment, thereby curing and pouring concrete within the mold central portion.
