multi-span continuous prestressed concrete girder bridge structure rigidly joined to pier

摘要

The subject innovation has a long gyeongganjang than at the same time and relates to that Ramen-type multi-span continuous PSC I-type girder bridge structure ganggyeol the pier has a lower girder height while having a good workability of PSC I-type girder bridge according to the prior art, vibration , is to be constructed to have excellent usability affordable multi-span continuous PSC I girder type bridges in such deflections.; Piers the subject innovation is the span is installed as the infrastructure in the continuous bridge; Is installed between the piers, a plurality of PS wire and the fixing device is formed of a bridge superstructure of PSC I-type girder; The pier was extended bonding the reinforcement protrusion extending from both ends of the protruding reinforcement and PSC girders to each other from the to pouring concrete, and characterized in that it comprises a PSC I-type girder and bridge columns each other ganggyeol that the bridge coupling unit, PSC Unlike the combined parts of the conventional and between the I-type girder and bridge columns coupler and the adjacent shift between a rigid frame formula ganggyeol structure eliminates the bridge bearings sikimeuroseo increase the indeterminate degree of the structural system to redistribute the load acting on the bridge for generating the PSC I-type girders hold the gyeongganjang than conventional PSC I-type girder is formed in the same cross-section by reducing the danmyeonryeok and at the same time can provide more construction of the bridge girder continuous PSC I-shaped girder having a low height.; That is, the continuous PSC I-type girder bridge structure according to the present invention is sikimeuroseo changed to rigid frame format of continuous indeterminate structural system for sikimeuroseo bridge Structural Systems integrated with each other the girder and pier and the adjacent shifts and integrated in a simple of construction T conventional simple on bridge bearings as compared with the mounted structure type is danmyeonryeok occurs less secure good usability in a gyeongganjang a long multi-span structure capable of constructing a continuous PSC I-shaped girder of the lower girder height to vibration, deflection bridge bearings that were conventionally used by bridges and by to allow for removal of the expansion joint it is capable of reducing the maintenance of public bridge repair costs economically span can be constructed of a continuous girder bridges PSC I type.
