It's essential to understand how the steel frame components of construction structures are manufactured. Firstly, steel mills produce the raw materials for steel structures through hot rolling processes (typically). Steel structure manufacturers then purchase these materials, cut them according to detailed drawings, and fabricate beams and columns for construction use. The finished steel structure components are transported to the construction site, where they are assembled by steel structure installers.
Where do the construction drawings on-site come from? The responsibility of the structural engineer is to plan, analyze, and verify the structures to be constructed, and create construction drawings that document the structural plans. The structural drawings only include overall requirements for the steel structure fabrication, i.e., descriptions of typical joints.
Then, the steel structure detail planner uses these construction drawings and overall node descriptions to plan detailed steel structure components and precise geometric shapes, creating detailed manufacturing drawings to better guide steel structure manufacturers on how to fabricate each component of the ongoing construction. The manufacturing drawings include detailed information such as material specifications, dimensions, welding, bolt connections, surface treatment, and coating requirements.
In the construction of steel frame lightweight panels, the钢结构construction only includes overall descriptions of the joints, while the processing encompasses all details required for the manufacture of each steel structural component.
It is important to note that in construction projects, the quantity of detailed drawings exceeds that of construction drawings significantly.
Steel structure manufacturers typically use CNC machines to actively cut steel beams and drill holes. Some manufacturers manually program the CNC machines based on the information in the processing drawings. Other manufacturers of steel frame lightweight panels use the aforementioned digital manufacturing models to program the CNC machines automatically.
