Irregular polygon power transmission double-limb tower connected through inner flanges
The invention discloses an irregular polygonal power transmission twin tower connected by inner flanges, the twin tower comprises single-limb towers arranged in pairs, the single-limb towers arranged in pairs image about a longitudinal plane, the cross section of the twin tower is an irregular polygonal cross section, and the shape of the cross section continuously changes along the longitudinal direction. Bending exists in the cross section transverse direction and the double-limb tower longitudinal direction, the double-limb tower is divided into a plurality of design sections in the longitudinal direction, the design sections comprise a tower bottom section, a tower top section and a plurality of tower middle sections, and the tower top section and the single tower middle section are each divided into at least two manufacturing sections. Longitudinal bending is manufactured in the mode that bending is replaced by straight bending, meanwhile, in order to guarantee the overall linear precision requirement of the double-limb tower, the design segments are divided into smaller manufacturing segments, and the overall linear and shape requirements of the double-limb tower are guaranteed; and the inner flange is adopted for connection, so that the structure has better wind resistance, the overall stability is enhanced, and the site construction difficulty and cost are reduced.
本发明公开了一种内法兰连接的不规则多边形输电双肢塔，该双肢塔包括成对布设的单肢塔，成对布设的单肢塔关于纵平面镜像，所述双肢塔横截面为不规则多边形截面，且横截面形状沿纵向方向不断变化，截面横向及双肢塔纵向均存在弯曲，所述双肢塔沿纵向方向划分为多个设计节段，所述设计节段包括塔底节段、塔顶节段和多个塔中节段，其中，塔顶节段和单个塔中节段分别划分为至少两个制造节段。本发明将纵向弯曲采用以直代曲方式进行制造，同时为保证双肢塔整体线型精度要求，将设计节段再进行划分，划分为更小的制造节段，保证双肢塔整体线型和形状要求；采用内法兰连接，使结构具有更好的抗风性能，增强了整体的稳定性，降低了现场施工难度和成本。
