Hollow steel pipe-UHPC (Ultra High Performance Concrete) three-column type tower for power transmission line tower
The invention relates to the technical field of power transmission line towers, in particular to a hollow steel pipe-UHPC three-column type tower for a power transmission line tower, which comprises a plurality of column limb sections of which the boundary dimensions are sequentially reduced from top to bottom. The hollow concrete prefabricated pipe is reasonable and compact in structure and convenient to use, local thickening is conducted on the inner side of the upper portion and the inner side of the lower portion of the hollow concrete prefabricated pipe, meanwhile, the inner tie bars are arranged in the thickening portions, the whole pipe is provided with the through outer tie bars, and the steel pipes fixedly installed together with the connecting flanges are arranged on the outer sides of the thickening portions in a sleeving mode; a plurality of studs with the inner ends located in the concrete prefabricated pipe are pre-planted in the steel pipe, so that the overall rigidity, connection strength, bearing capacity and stability of the column limb are effectively improved, the material strength is fully utilized, the steel distribution rate of the column limb is effectively reduced, the concrete consumption is saved, the dead weight of the column limb is reduced, seismic resistance is facilitated, the material consumption is also saved, and transportation and hoisting are facilitated; and the construction cost is reduced, and good economic benefits are achieved.
本发明涉及输电线塔技术领域，是一种输电线塔用空心钢管‑UHPC三柱式塔架，其包括若干个从上至下外形尺寸依次减小的柱肢节段。本发明结构合理而紧凑，使用方便，其通过对中空混凝土预制管上部内侧和下部内侧进行局部加厚，同时在加厚部位内设置内拉筋，整管设置通长的外拉筋，以及在加厚部位外侧套装与连接法兰固定安装在一起的钢管，并在钢管内预植若干内端位于混凝土预制管内的栓钉，有效提高了柱肢整体的刚度、连接强度、承载力和稳定性能，还充分利用材料的强度，有效降低柱肢配钢率，节省混凝土用量，减轻了柱肢自重利于抗震，也节约了材料用量，便于运输和吊装，降低了工程造价，具有良好的经济效益。
