Construction method of large-span steel box girder
The invention provides a construction methodof a large-span steel box girder. The method is used for hoisting a steel box girder with the length larger than 40 m and comprises the following steps that S1, finite element analysis software and a building information model are adopted for conducting computer analogue simulation on the construction process of the steel box girder; S2, a steel box girder unit and a column top steel cross beam are manufactured according to an analogue simulation result; S3, the steel box girder units are assembled into the steel box girder on the temporary jig frame; S4, the column top steel cross beams are installed at the two ends of the midspan correspondingly; and S5, the steel box girder is hoisted to the two column top steel cross beams, and the two ends of the steel box girder are fixed to the two column top steel cross beams correspondingly. No temporary support is arranged in the midspan, and the steel box girder is mounted in the whole midspan, so that the pressure of engineering construction on traffic can be effectively reduced, and the construction efficiency, especially a busy central urban area, is improved; and the steel beam mounting precision can be guaranteed through computer analogue simulation, and the design and specification requirements are met.
本发明提供了一种大跨度钢箱梁的施工方法，所述方法用于吊装长度大于40米的钢箱梁，所述方法包括以下步骤：S1、采用有限元分析软件和建筑信息模型对所述钢箱梁的施工过程进行计算机仿真模拟；S2、根据仿真模拟结果制作钢箱梁单元和柱顶钢横梁；S3、在临时胎架上将钢箱梁单元拼装成所述钢箱梁；S4、在跨中的两端分别安装所述柱顶钢横梁；S5、将所述钢箱梁吊装至两个所述柱顶钢横梁上，并将所述钢箱梁的两端分别固定在两个所述柱顶钢横梁上。在跨中不设临时支撑，整跨安装钢箱梁，能够有效降低工程施工对交通造成的压力并提高了施工效率，特别是交通繁忙的中心城区；通过计算机仿真模拟能够保证钢梁安装的精度，满足设计及规范要求。
