Main tower column using prestress as stress control and construction method thereof
A main tower column using prestress as stress control comprises a tower bottom section, a lower inclined section, an upper inclined section and a tower top section which are sequentially poured from bottom to top, a lower cross beam is arranged between the lower inclined section and the upper inclined section, a middle cross beam is arranged between the upper inclined section and the tower top section, and an upper cross beam is arranged in the middle of the tower top section. A stay cable is arranged on the tower top section; the lower inclined section is arranged on the tower bottom section in an inclined mode, the lower inclined section comprises two lower pouring sections which are oppositely arranged, and the lower pouring sections incline outwards from bottom to top; compared with the prior art, in the tower column construction process, the pre-tightening assembly and the pre-supporting assembly are arranged on the upper side and the lower side of the section of the tower limb, and the pre-tightening assembly and the pre-supporting assembly are subjected to pre-stress tensioning; the situation that the pressure stress on the inner side and the pressure stress on the outer side of the tower column generated under the action of the self weight, the creeping formwork body and other temporary loads are inconsistent is controlled, and it is guaranteed that the tower column has the better vertical line and stability in the construction process.
一种利用预应力作为应力控制的主塔塔柱，包括自下而上依次浇筑的塔底段、下部倾斜段、上部倾斜段和塔顶段，下部倾斜段与上部倾斜段之间设有下横梁，上部倾斜段与塔顶段之间设有中横梁，塔顶段中部设有上横梁，且塔顶段上设有斜拉索；所述下部倾斜段倾斜式设置于塔底段上，且下部倾斜段包括两根相对设置的下部浇筑段，下部浇筑段自下而上向外倾斜；与现有技术相比，在塔柱施工过程中在塔肢截面的上下侧进行预紧组件和预撑组件的布置，并且对预紧组件和预撑组件进行预应力的张拉，实现对塔柱在自重、爬模架体和其他临时荷载的作用下的产生的内外侧的压应力不一致的情况的控制，确保塔柱在施工过程中具有更好的竖直线和稳定性。
