Prestressed flexible diagonal web member structure of steel pipe truss type high wind tower and construction method
The invention relates to a prestressed flexible diagonal web member structure of a steel pipe truss type high wind tower and a construction method. The structure comprises a tower column, a cross rod, an arc-shaped flange plate, a diagonal steel strand pair and a tensioning bracket, wherein the cross rod is connected to the tower column through the arc-shaped flange plate; the diagonal steel strand pair is used for forming a prestressed flexible diagonal web member, the lower end of the diagonal steel strand pair is a locking end and is locked at the upper part of the arc-shaped flange plate, and an anchoring point adopts a locking end extrusion type anchorage device; the upper end of the diagonal steel strand pair is a tensioning end and penetrates through the lower part of the arc-shaped flange plate, an anchoring point of the tensioning end and the lower part of the arc-shaped flange plate adopts an adjusting end clamping piece type anchorage device, and the adjusting end clamping piece type anchorage device is connected with an anti-loosening thread cap through threads; and the tensioning bracket is fixedly connected with the tower column, is arranged on an extension line at the upper end of the diagonal steel strand pair, and is used for providing a working platform for tensioning the diagonal steel strand pair. Compared with the prior art, the prestressed flexible diagonal web member structure has the advantages that steel consumption is reduced, the fatigue resistance is excellent, the construction is convenient, the maintenance is simple, and the adaptability is strong.
本发明涉及一种钢管桁架式高风塔预应力柔性斜腹杆结构及施工方法，结构包括塔柱、横杆、弧形法兰板、斜钢绞线对和张拉牛腿；横杆通过弧形法兰板连接于塔柱上；斜钢绞线对用于形成预应力柔性斜腹杆，斜钢绞线对的下端为锁固端，锁固于弧形法兰板的上部，锚固点采用锁固端挤压式锚具；斜钢绞线对的上端为张拉端，穿过弧形法兰板的下部，且张拉端与弧形法兰板下部的锚固点采用调节端夹片式锚具，调节端夹片式锚具通过螺纹连接有防松螺纹帽；张拉牛腿与塔柱固定连接，并设置于斜钢绞线对上端的延伸线上，用于为斜钢绞线对的张拉提供作业平台。与现有技术相比，本发明用钢量省、抗疲劳优、施工方便、维护简单、适应性强。
