Tensioning device and tensioning method for stay cable
The invention provides a tensioning device and a tensioning method of a stay cable, and relates to the technical field of bridge construction, the tensioning device is provided with a connecting assembly and a tensioning assembly, the connecting assembly is arranged in an anchor box at a box girder end or in a main tower, a cable body penetrates through the connecting assembly, an anchor backing plate is arranged in the anchor box, a mounting slope is arranged in the main tower, and the tensioning assembly is arranged in the mounting slope. The tensioning assembly comprises a supporting seat and a hydraulic nut, one end of the supporting seat is correspondingly attached to an anchor bearing plate in an anchor box at the box girder end or an installation slope in a main tower, the other end of the supporting seat is connected with one end of the hydraulic nut, and the other end of the hydraulic nut is attached to the connecting assembly. The hydraulic nut pushes the supporting base to enable the connecting assembly to move in the direction away from the supporting base so as to stretch the cable body. The connecting assembly and the tensioning assembly are arranged in the anchor box at the box girder end or in the main tower, the hydraulic nut pushes the supporting seat to tension the cable body, and the connecting assembly and the tensioning assembly are compact in structure and small in size and can be conveniently arranged in the anchor box at the bridge box girder end or in the main tower, so that the construction requirement is met.
本发明提供了一种斜拉索的张拉装置及张拉方法，涉及桥梁建设施工技术领域，张拉装置设有连接组件和张拉组件，连接组件设于箱梁端的锚箱内或主塔内，索体穿束于连接组件内，锚箱内设有锚垫板，主塔内设有安装斜面，张拉组件包括支撑座和液压螺母，支撑座的一端对应与箱梁端的锚箱内的锚垫板或主塔内的安装斜面贴合，支撑座的另一端与液压螺母的一端连接，液压螺母的另一端与连接组件贴合，液压螺母顶推支撑座使连接组件向远离支撑座的方向移动以张拉索体。本发明的连接组件和张拉组件设于箱梁端的锚箱内或主塔内，液压螺母顶推支撑座以张拉索体，连接组件和张拉组件结构紧凑尺寸较小，便于设置于桥梁箱梁端的锚箱内或主塔内，满足施工需求。
