Externally-hung cast-in-place box girder prestress tensioning platform and construction method thereof
The invention belongs to an externally-hung cast-in-place box girder prestress tensioning platform and a construction method thereof. The prestress tensioning platform comprises an externally-hung tensioning platform body, a movable hanging bracket and a guide rail. The externally-hung tensioning platform body is provided with a bottom frame controlled by a hydraulic cylinder, an arm frame and a tensioning hydraulic cylinder which is flexibly moved through a butt-joint disc and a movable plate to align with a cast-in-place box girder prestress tensioning steel bar. The externally-hung cast-in-place box girder prestress tensioning platform can be matched with a movable hanging bracket or a forklift to conduct tensioning operation on cast-in-place box girder prestress steel bars on the upper end face of a cast-in-place box girder or the ground at the front end of the cast-in-place box girder according to different geographic positions of the cast-in-place box girder. And a constructor can place and operate the tensioning hydraulic cylinder on the tensioning platform in cooperation with mechanical operation, and the defects of a traditional method are overcome. The construction method has the advantages of wide construction surface, mechanical operation, transverse movement alignment, time and labor saving in placement of the tensioning hydraulic cylinder, good safety, high efficiency and high construction speed.
本发明属于外挂式现浇箱梁预应力张拉平台及其施工方法，预应力张拉平台包括外挂式张拉平台、移动吊架、导轨，外挂式张拉平台设由液压缸控制的底架、臂架及且通过对接盘、活动板灵活移动张拉液压缸对齐现浇箱梁预应力张拉钢筋。本发明的外挂式现浇箱梁预应力张拉平台能根据现浇箱梁所处的地理位置不同配合移动吊架或叉车在现浇箱梁上端面或现浇箱梁前端地面对现浇箱梁预应力钢筋实施张拉作业，且施工人员在张拉平台上能配合机械操作放置操作张拉液压缸，克服了传统方法的缺点。本发明有施工面宽敞、机械化操作，横移对位、放置张拉液压缸省时省力、安全性好、效率高、施工速度快的优点。
