Variable cross-section stepped steel box arch section and assembling method
The invention relates to a variable cross-section stepped steel box arch section and an assembling method. The section size of the variable cross-section stepped steel box arch section exceeds 6 meters, and the requirement of four types of road transportation ultra-wide and ultra-high standards is met. According to the manufacturing method, by designing a reasonably designed partitioning scheme, an assembling sequence and a technological process, the manufacturing problem of the steel box arch section of a single-double combined stepped box-shaped section structure is solved. The method has the remarkable effects on the aspects of controlling welding deformation, guaranteeing the manufacturing precision, improving the assembling efficiency and reducing the manufacturing cost, and fills the blank of the manufacturing technology of the variable-cross-section stepped steel box arch section. Compared with a traditional steel box arch segment assembling method, the method has the advantages of being convenient to operate, ingenious in conception, convenient and rapid, and has very high practicability and popularization value. The method has high applicability and operability, meanwhile, safety risks in the operation process are reduced, reference can be provided for manufacturing of similar steel members in the future, and the good reference effect is achieved.
本发明涉及一种截面尺寸超过6米，达到四类道路运输超宽超高标准要求的变截面阶梯式钢箱拱节段及组拼方法。本发明通过设计合理的分块方案、组装顺序和工艺流程，解决了单双结合“阶梯式”箱形断面结构的钢箱拱节段制造难题。本发明在控制焊接变形、保证制造精度、提高组拼效率、降低制造成本方面具有显著效果，弥补了变截面阶梯式钢箱拱节段制造技术空白。与传统的钢箱拱节段组拼方法比较，本发明具有便于操作、构思巧妙、方便快捷的优点，具有很高的实用性和推广价值。本发明具备较强的适用性和可操作性，同时减少了操作过程中的安全风险，可以为以后同类钢构件的制造提供了参考，起到很好的借鉴作用。
