Multi-section steel box girder splicing method
The invention discloses a multi-section steel box girder splicing method, relates to the technical field of steel box girder construction, and solves the problem that the machining and hoisting precision of an existing steel box girder cannot be controlled. The method comprises the steps of machining, hoisting and welding initial steel box girder sections to obtain to-be-spliced steel box girder sections; performing data acquisition on the to-be-spliced steel box girder sections to obtain first-stage data; processing and analyzing the first-stage data to obtain second-stage data; generating a segment component scanning model by using the second-stage data, and generating a simulation pre-assembly model; fitting and comparing the simulation pre-assembly model and a theoretical model to obtain deviation data of the simulation pre-assembly model; adjusting the to-be-spliced steel box girder sections according to the deviation data, and acquiring the adjusted steel box girder sections; and splicing the adjusted steel box girder sections on site. By the adoption of the method, precise construction of pre-assembly of the steel box girder is achieved, the construction efficiency is greatly improved, and the construction cost is reduced.
本申请公开了一种多节段钢箱梁拼装方法，涉及钢箱梁施工技术领域，解决了现有钢箱梁加工及吊装精度无法控制的问题。该方法包括：对初始钢箱梁节段进行加工、吊装并焊接得到待拼接钢箱梁节段；对待拼接钢箱梁节段进行数据采集得到第一阶段数据；对第一阶段数据处理和分析得到第二阶段数据；利用第二阶段数据生成节段构件扫描模型，并生成模拟预拼装模型；将模拟预拼装模型与理论模型拟合比对得出模拟预拼装模型的偏差数据；根据偏差数据调整待拼接钢箱梁节段，得到调整后钢箱梁节段；对调整后钢箱梁节段进行现场拼装。采用本申请实现了对钢箱梁预拼装的精确施工，且大大提高施工效率，降低施工成本。
