inner points of the rising and falling of the connection with the introduction of the compressive force that the floor plate is omitted continuous prestressed concrete the concrete construction method

摘要

The present invention provides a concrete floor plate was introduced in connection with the compression force rise and fall of the medial branch is omitted continuous prestressed concrete structures as on the construction method of the upper flange and a lower flange and prestressed concrete girders is formed shear key fabricated on the side of the cross beam abuts the flange and flange-mounted on the bottom in the transverse direction of the bridge girder structure and connected by steel girders connecting the longitudinal direction, and has elevated the inner points after the epoxy mortar or a shear key between the longitudinal and transverse directions gap between the abutting girder and the girder to girder to girder charge sikimyeo PC steel tension in the transverse direction After weaving by which the prestressed girders and girders in the transverse direction by lowering the inner point was raised again characterized by introducing the prestressing of the connection to the niche. ; rise of the inner points presented in the invention and Plates of continuous prestressed concrete construction method of concrete structures is omitted, which introduces the compression force in connection with the lowering of the bottom plate and concrete structure because it is not so much the number of lower-type pick of the entire bridge structure in bridge structure can be introduced in the prestressed connection There may also allow the behavior of a continuous gyoro. May also be enough to bridge structures that can replace the existing prestressed box girder bridges in each of the fabricated concrete I-girders in the transverse direction by integrating the entire structure had the great torsional rigidity in the field.
