高强度单根钢筋在新澳凼大桥工程中得到多方面的应用:一是用为少数后张法预应力混凝土结构—35m 跨连续梁主桥的装配式桥墩和航道主桥斜拉桥跨的边纵主梁悬拼段的预应力筋;二是用为斜拉桥跨的墩顶横主梁与锚墩以及边纵主梁与锚墩和索塔的锚筋;三是用为一些临时性钢结构与工程结构的连续筋,还用为提升大型构件的吊杆,等等。单根资用拉力接近1000kN,用途广泛。本文特谈谈其在第一个方面的应用。
High-strength single steel bars in the New Macau-Taipa Bridge project has many applications: First, with a few post-tensioned prestressed concrete structure -35m continuous beam main bridge of the bridge pier and the main bridge cable-stayed bridge span Side of the main girder Suspension section of the prestressed tendons; the second is used for the cable-stayed bridge across the main pier and anchor pier and the side of the main girder and anchor pier and pylon anchor tendons; the third is used for some temporary Continuous steel structure and engineering structure of the tendons, but also for the lifting of large components boom, and so on. Rigid single force close to 1000kN, a wide range of uses. This article especially talk about its application in the first area.
