Embodiment Construction
[0013] Such as figure 1 As shown, taking the construction of a "herringbone"-shaped steel tower as an example: first, set up a simple temporary support 13 under the steel tower 1 and the inclined legs 2, and make a certain angle a between the steel tower 1 and the inclined legs 2, and the steel tower 1 Can not overlap with the inclined leg 2 in parallel to avoid self-elevation difficulties, and then use the lifting equipment on the ground to tailor weld the steel tower 1 and the inclined leg 2 on the temporary support 13. Install the hinge 3 at the bottom of the steel tower; install the hinge 4 between the steel tower 1 and the inclined leg 2 (for the single-column steel tower, the auxiliary leg 2 can be set on the main body of the steel tower 1); install the slideway 6; install the inclined leg 2 Bottom ball boot 14 (or hinge) and slide plate 5, slide plate 5 is positioned on slideway 6; Then prestressed steel strand 7 is set between steel tower base and auxiliary leg bottom,...
