Steel strand mounting method for wind driven generator supporting tower frame prestressed structure

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of wind power generation, more specifically, to a steel strand installation method for a prestressed structure of a wind power generator support tower. Background technique [0002] In the prior art, when installing steel strands for supporting towers of wind power generators, equipment such as large cranes, high-power winches, and large-capacity jacks are usually used. A dozen or even dozens of steel strands weigh several tons at every turn, which not only has low operating efficiency, high energy consumption costs, and a high risk factor, but also the installed steel strands are easy to interfere with each other, which can easily lead to damage to the steel strands. Relaxation affects the tension effect.
