Anchoring conversion construction method for vertical prestressed tendons
The invention discloses a vertical prestressed tendon anchoring conversion construction method, belongs to the technical field of prestressed tendon installation, and solves the problem that cables are difficult to penetrate through a small-diameter reserved hole channel integrally at present. The method comprises the steps that a cable head device is used for manufacturing a cable, and a whole cable body with the diameter smaller than that of a reserved hole channel is obtained; then the whole bundle of cable bodies are hoisted through a hoisting device to penetrate through the reserved hole channel, then a lifting device is replaced to serve as a temporary hoisting tool, an anchor plate is installed, and the whole bundle of cable bodies are hoisted again; and finally, the anchor plate is lowered to a preformed hole opening, a working clamping piece is installed, and anchoring conversion of the prestressed tendon is completed. According to the vertical prestressed tendon anchoring conversion construction method, rapid cable hanging of a small-diameter reserved hole channel can be met, and the construction efficiency is effectively improved.
本发明公开了一种竖向预应力筋锚固转换施工方法，属于预应力筋安装技术领域，解决目前对于小直径的预留孔道难以整体穿索的问题。该方法是先用索头装置制索，得到直径小于预留孔道直径的整束索体；然后用吊装装置将整束索体起吊穿过预留孔道，再更换提升装置作为临时起吊工具，安装锚板，将整束索体再次提升；最后下放锚板至预留孔道口，安装工作夹片，完成预应力筋的锚固转换。本发明的竖向预应力筋锚固转换施工方法，能够满足小直径预留孔道的快速挂索，有效提高施工效率。
