随着建筑钢结构在工业厂房的广泛应用,但重型工业钢结构厂房由于行车吨位大、跨度大、格构柱超长且自重大、现场条件等不利因素制约,造成道路运输十分困难,所以车间必须分成两节制作,现场空中对接焊接施工。该成果的应用不仅确保工程的质量达到优良的目标,而且节约投资、缩短工期,使综合经济效益显著。本文就以一新建厂房为例介绍一下钢结构重型工业厂房二节柱现场焊接施工技术的研究。 With the wide application of structural steel structures in industrial plants, heavy-duty industrial steel plant buildings are difficult to transport due to unfavorable factors such as large tonnage, large spans, long lattice columns, large self-heavy columns, and site conditions. It must be divided into two sections for production and on-site aerial butt welding construction. The application of this achievement not only ensures that the quality of the project achieves excellent goals, but also saves investment, shortens the construction period, and makes the overall economic benefits significantly. This article takes a new factory as an example to introduce the research on the field welding construction technology of two-column heavy-duty industrial building.
