Steel strand mounting method for wind driven generator supporting tower frame prestressed structure
The invention provides a steel strand mounting method for a wind driven generator supporting tower frame prestressed structure. The steel strand mounting method includes the steps that tower top anchorage devices and tower bottom anchorage devices are mounted; single steel strands are pulled into target tower bottom anchor holes through a winch, and tower bottom clamping pieces are used for anchoring; steel strands are pulled into target tower top anchor holes, and tower top clamping pieces are used for anchoring the steel strands; the target tower top anchor holes and the target tower bottomanchor holes are converted until a first preset number of target tower top anchor holes and a first preset number of target tower bottom anchor holes are hung and anchored; and the tower top anchoragedevices and the tower bottom anchorage devices are converted until a second preset number of tower top anchorage devices and a second preset number of tower bottom anchorage devices are hung and anchored. The steel strands are mounted in the manners of single hanging and tensioning and opposite angle mounting, the mounting efficiency is high, the safety coefficient is large, the energy consumption is low, mounting is stable, the problems of mutual twisting, winding and interfering between the mounted steel strands are solved, the height of a foundation inner cavity of a tower barrel is reduced, and the material cost, the construction cost and the labor cost are reduced.
本发明提供一种用于风力发电机支撑塔架预应力结构的钢绞线安装方法，包括步骤：安装塔顶锚具和塔底锚具；利用卷扬机将单根钢绞线牵引至目标塔底锚孔中，利用塔底夹片进行锚固；将钢绞线索引至目标塔顶锚孔中，利用塔顶夹片对钢绞线进行锚固；变换目标塔顶锚孔及目标塔底锚孔，直至第一预设数量个目标塔顶锚孔及目标塔底锚孔吊设及锚固完成为止；变换塔顶锚具及塔底锚具，直至第二预设数量个塔顶锚具及塔底锚具吊设及锚固完成为止。本发明采用单根挂设和张拉、对角安装的方式安装钢绞线，安装效率高、安全系数大、能耗低、安装平稳，解决了安装后的钢绞线之间相互扭转、缠绕和干扰的问题，降低了塔筒的基础内腔高度、节约了材料、施工及人力成本。
