Construction method of large-span fine aggregate concrete H-shaped steel stiff beam
The invention relates to a construction method of a large-span fine aggregate concrete H-shaped steel stiff beam, which can accurately splice a large-span steel beam in the air through connecting steel plates, connecting bolt holes and connecting bolts, can adopt a three-dimensional simulation method of BIM (Building Information Modeling) to determine the spatial relationship of a beam column and the like so as to accurately position the bolt holes, and can perform the steel beam mounting process on a construction site. If hole position deviation exists, a BIM reverse design method is adopted, three-dimensional scanning is carried out on the steel beam position deviation on the construction site, and hole size fine adjustment is carried out on other steel beams subjected to next construction; the double-truss steel beam construction technology is adopted, double-truss steel beams can be poured at a time, an expansion joint structure is formed, the two sides of the expansion joint can be poured at the same time, the construction efficiency is greatly improved, the formwork position can be adjusted, the slurry leakage problem is solved by changing the formwork structure, and the expansion joint quality is guaranteed.
本发明涉及一种大跨度细石混凝土H型钢劲性梁施工方法，通过连接钢板、连接螺栓孔、连接螺栓的方式，可在空中准确拼接大跨度钢梁，并且可采取BIM的三维模拟方法，确定梁柱等空间关系进行螺栓孔的精确定位，在施工现场进行钢梁安装过程，若有孔位偏差，则采用BIM逆向设计方法，三维扫描施工现场钢梁位置偏差，对接下来其他施工的钢梁进行孔洞尺寸微调；采用双榀钢梁施工技术，一次即可浇筑双榀钢梁并形成伸缩缝结构，伸缩缝两侧可同时浇筑，大大增加施工效率，且模板位置可调节并通过模板结构改变使得漏浆问题得到改善，伸缩缝质量得到保证。
