STEEL-CONCRETE COMPOSITE HYBRID INTEGRATED CONTINUOUS BRIDGE SYSTEM USING CAST STEEL NODE AND PRECAST SLAB, AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a steel-concrete composite hybrid integrated continuous bridge system using a cast steel node, capable of realizing a load-saving maintenance structure for a bridge, and a precast slab, and a construction method thereof. According to the present invention, a method to construct an integrated continuous bridge comprises: a step of installing an abutment on both sides and installing a plurality of piers between the abutments, wherein a cast steel node structure is installed in each pier; a step of mounting a girder connecting the abutment and the pier on the cast steel node structure, wherein the girder is temporarily fixed in the cast steel node structure by using a buffering member installed in the girder; a step of welding and attaching the temporarily fixed girder to the cast steel node structure; a step of mounting the precast slab on the girder and using a connection member to couple the precast slab to the girder; and a step of depositing concrete between the abutment and the precast slab, and between the pier and the precast slab.;COPYRIGHT KIPO 2018
