The present invention is connected to the tendon which minimizes the tendon or the amount of the steel bar is applied to the girder, and maximizes the prestress introduced to the girders as well as improving the economy, so as to reduce the stress generated in the girder by the external force after construction effectively support using the there is provided a rigid frame bridge construction method.
Frame Bridge construction method using the connection support the tendon according to the present invention for achieving the above object after installing the formwork and place the sheath, connected to anchorage, connecting the support to a predetermined position in the mold, the concrete in the formwork by the casting and curing by installing on both ends of the anchorage after the formation of the concrete member, said concrete member, and inserting the tendon in the sheath, the tension step of manufacturing a concrete girder; Forming a concrete alternately be that the concrete girders are installed to form a steel wall provided with a connection anchorage in the upper end of the shift; The method comprising mounting a concrete girder on the shift; Inserting a yuapjaek connection between the steel support and the wall of the concrete girders, and loading a load into the yuapjaek; After said step of loading, by inserting a bolt or Shim close connection between the steel support and the wall of the concrete girders; Inserting a tendon or a rod, and the tension to the tendon or rod connection between the anchorage of the connection and the steel wall anchorage of the concrete girders; It characterized by forming a slab made of an step by pouring concrete on the steel girders and the concrete wall.
Further, Frame Bridge construction method using the connection support and tendon according to the present invention for achieving the above objects includes the steps by installing a steel beam welded to the connection support and connected to anchorage of manufacturing a steel girder; Forming a concrete alternately become the steel girder and the installation, form a steel wall provided with a connection anchorage in the upper end of the shift; The step of mounting a steel girder on the shift; Inserting a yuapjaek connection between supports and the steel wall of the steel girder and loading a load into the yuapjaek; The step of sandwiching a bolt or Shim close contact between the support and the connection of the steel wall after the loading, steel girder; Inserting a tendon or a rod, and the tension to the tendon or rod connection between the anchorage of the anchorage and connection steel wall of the steel girder; It characterized by forming a slab made of an step by pouring concrete on the steel girder and the steel wall.
