Structural Steel Roof Load Safety Inspection and Appraisal

What are the advantages of steel structures?

(1) High Stability of Steel Structures: Compared to traditional brick and concrete structures, as well as reinforced concrete factory structures, steel structure factories offer exceptional stability, which is evident in two aspects. Firstly, steel structures have excellent seismic performance due to the high strength and light weight of steel, and their strong integrity with uniformly distributed internal materials, making them well-suited to meet the mechanical requirements of factory construction. Secondly, steel structures exhibit excellent load-bearing capabilities, as steel's excellent toughness and plasticity allow it to withstand significant structural deformation, resulting in clear load-bearing effects.

(II) Construction period for steel structures is shorter

Compared to traditional brick-and-concrete factory structures, steel structures exhibit distinct industrial characteristics. With ready-made steel products and straightforward installation procedures, they can significantly reduce construction timelines. Standard steel structures typically come pre-drilled and pre-assembled for easy positioning and welding according to specific requirements. In cases where factory relocation is necessary, steel structures can be easily disassembled and reused in new construction, thereby shortening timelines and effectively reducing construction costs, offering excellent economic benefits.

(3) Structural steel has energy-saving and environmental protection features

Compared to brick-and-mortar and reinforced concrete structures, steel structures exhibit strong green energy-saving efficiency, both in terms of material sourcing and construction processes. Steel construction generates minimal dust and noise, significantly reducing its impact on the surrounding environment. Moreover, the new wall materials compatible with steel structures also boast strong environmental performance, enhancing the overall green quality of the factory structure in multiple aspects.

1) Categorize and conduct welding process tests based on joint types, determining welding methods, equipment, materials, process parameters, welding sequence, bevel shapes, etc.

2) Develop a reasonable and feasible welding process based on the results of the welding test.

3) Design process equipment that guarantees welding quality and facilitates control of welding deformation, ensuring the effective implementation of welding processes and effective control over welding deformation.

4) Develop a quality control plan for critical welds, strictly overseeing production processes such as raw material re-inspection, cutting, assembly, welding, and non-destructive testing.

3 Precision control of steel structure engineering drilling

Steel structural chord members, integral joints, joint plates, and splicing plates have a large number of holes and complex connection relationships. The accuracy directly affects the progress and quality of bridge installation and the geometric shape of the completed bridge. Therefore, high precision in hole making is required. The following measures are taken:

1) Focus on the post-drilling process with pre-drilling as a supplement for hole-making, to minimize the impact of welding distortion and enhance the precision of hole creation.

2) Design high-precision precision marking and precision drilling processes.

3) Design high-precision hole-making equipment, including drilling templates and drilling fixtures.
