PREFABRICATED HYBRID GIRDER CAPABLE OF APPLYING PRESTRESS TO GIRDER USING GAP DIFFERENCE BETWEEN CONTACT SURFACES OF CONNECTIVE PARTS OF BLOCKS, METHOD FOR APPLYING PRESTRESS TO PREFABRICATED HYBRID GIRDER, CONTINUATION METHOD FOR PREFABRICATED HYBRID GIRDER, AND MANUFACTURING AND ASSEMBLING METHOD THEREOF
PREFABRICATED HYBRID GIRDER CAPABLE OF APPLYING PRESTRESS TO GIRDER USING GAP DIFFERENCE BETWEEN CONTACT SURFACES OF CONNECTIVE PARTS OF BLOCKS, METHOD FOR APPLYING PRESTRESS TO PREFABRICATED HYBRID GIRDER, CONTINUATION METHOD FOR PREFABRICATED HYBRID GIRDER, AND MANUFACTURING AND ASSEMBLING METHOD THEREOF
The present invention relates to a prefabricated hybrid girder composed of precast concrete blocks and steel blocks used as an upper structure of a bridge, and more specifically, to a prefabricated hybrid girder in which two precast concrete blocks are arranged on the outsides thereof, a center block for connecting the same is formed with the steel block, and a gap difference is formed between contact surfaces of connective parts between the blocks to automatically apply prestress force using the gap difference when the blocks are assembled.
