CONTINUOUS GIRDER BRIDGE HAVING COMPOSITE NON-UNIFORM SECTION STRUCTURE AND CONSTRUCTION METHOD THE SAME

摘要

The present invention relates to a continuous girder bridge and a construction method thereof having a composite sectional cross-section structure that can be easily placed in the concrete lower section of the girder under the compressive stress of the parent cement portion.;In the continuous girder bridge having a composite cross section structure according to an embodiment of the present invention, an area of the girder supported by the lower structure of the bridge is composed of a composite cross section girder, and the composite cross section girder is formed at both ends of the abdominal plate. The lower flange is provided, the end of the lower flange is provided with a reinforcement jaw in a structure capable of placing concrete, the lower flange upper surface between the reinforcing jaw and the abdominal plate may be made of a structure in which concrete is synthesized.;By the above configuration, the present invention can be easily made of concrete to be synthesized in the area where the parent moment occurs, the concrete can be placed before and after the installation of the girder to improve the workability and It is possible to shorten the air and to increase the load capacity of the continuous steel bridge to reduce the weight of the double composite steel bridge.;Steel box girder, continuous bridge, section, concrete, parent
