装配式预应力钢纤维混凝土杆塔的研制与应用

摘要

In this paper, the design, test and engineering application of the assembled prestressed steel fiber reinforced concrete pole tower are introduced systematically. For the design of the pole tower, the standardization and modularization components are adopted, which are in accordance with the production of parts. The mechanical behavior of both pole tower structure and every component meets the code requirements. For the engineering application of the pole tower, all the components (including the poles, crossing braces, horizontal arms, ground wire brackets, etc. ) are prefabricated in the factory, and then are assembled in the site, which brings about better engineering quality and higher construction speed. All of these have the features of construction industrialization, the concepts of which could give a reference to other engineering.%系统介绍了装配式预应力钢纤维混凝土杆塔的设计、试验研究以及工程应用全过程.预应力钢纤维混凝土杆塔设计上采用标准化、模数化构件,符合部品化生产的特点;杆塔整体及各构件受力性能均满足规范要求；工程应用时,杆塔所有组成构件(包括杆段、叉梁、横担、地线支架等)均采用工厂预制化生产,现场装配化施工,既保证了工程质量又加快了施工进度,具备建筑工业化的生产特点,相关理念值得其它工程借鉴.
