Segmented installation method for high-altitude large-diameter steel pull rod
The invention discloses a high-altitude large-diameter steel pull rod segmented installation method, which belongs to the field of steel structure construction, and comprises the following steps of: installing a tensioner at the upper end of a lower section of steel pull rod, and connecting the lower end of the steel pull rod with an upper lug plate of a pull-down structure through a pin shaft; the steel pull rod and the pull-down structure are lifted in place, and butt joint with the pull-up structure is completed; an operation platform is erected at the upper section steel pull rod part; hoisting the upper section of steel pull rod to the mounting position according to the angle of the lower section of steel pull rod, suspending the steel pull rod, and keeping the pull rod in a linear state; a tensioner is screwed into the upper section of the steel pull rod, so that the whole steel pull rod is assembled and contracted to be close to the minimum length; lifting the whole steel pull rod to be inserted into an upper lug plate; the extensions of the upper and lower sections of steel pull rods are adjusted to be consistent, steel pull rod joints are adjusted to be in butt joint with pin shaft holes in the lug plates, and pin shafts are inserted; by means of the high-altitude steel tie rod installation method and device, segmented installation of the steel tie rod in a high-altitude narrow space is achieved, and the workload of high-altitude installation is reduced.
本发明公开了一种高空大直径钢拉杆分段安装方法，属于钢结构施工领域，步骤为：将张紧器安装在下节钢拉杆上端，钢拉杆下端与下拉结构上耳板用销轴连接；将钢拉杆和下拉结构提升到位，完成和上拉结构的对接；在上节钢拉杆部位搭设操作平台；按照下节钢拉杆的角度，吊装上节钢拉杆到安装位置，将钢拉杆悬挂，并使拉杆保持直线状态；在上节钢拉杆旋入张紧器，使整根钢拉杆组装收缩到接近最小长度；提升整根钢拉杆插入上耳板；调节使上下节钢拉杆伸长量保持一致，调节钢拉杆接头与耳板上销轴孔对接，并插入销轴；调节张紧器使钢拉杆达到设计的预拉力，锁紧全部护套，本发明实现了高空狭小空间内，钢拉杆的分段安装，减少了高空安装的工作量。
