Construction Knowledge of Steel Frame Lightweight Panels

It's essential to understand how the steel frame components that make up the construction structure are manufactured. Firstly, steel mills produce the raw materials for steel structures through the hot rolling process (usually). Steel structure manufacturers then purchase these raw 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 on-site construction drawings 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 design. The structural drawings only include overall requirements for the steel structure fabrication, specifically the 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 processing drawings for better guidance on how to manufacture each steel structure component under construction. The processing drawings include detailed information such as material standards, dimensions, welding, bolt connections, surface treatment, and painting requirements.

In the construction of steel frame lightweight panels, only general descriptions of the joints are included, while the processing involves all the details necessary for manufacturing each steel structural component.

It's 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主动 cut steel beams and drill holes. Some manufacturers manually program the CNC machines based on information from the detailed drawings. Other manufacturers of steel frame lightweight panels utilize the aforementioned digital manufacturing models to automatically program the CNC machines.
