As a widely used structural form in modern construction engineering, the production method of steel structure usually includes the following steps:
Design and material selection: According to the specific needs of the project, such as load, span, building height, etc., the structural design is carried out, and the appropriate steel type and model are selected.
Cutting: According to the design drawings, use plasma cutting machines, laser cutting machines and other equipment to accurately cut the steel.
Welding: Welding is a key step in the fabrication of steel structures. Commonly used welding methods include manual arc welding, submerged arc welding, and gas shielded welding. The welding process is subject to relevant national or international standards, such as AWS D11 or EN 1090 to ensure welding quality.
Assembly: The cut steel is assembled according to the design drawings, a step that usually involves high-strength bolted or welded connections.
Correction: Calibrate the assembled steel structure to ensure that it meets the size and shape of the design requirements.
Rust removal and coating: In order to prevent steel from corroding, it is usually necessary to remove rust from the steel structure and apply anti-rust paint or anti-corrosion coating.
Component acceptance: Conduct quality checks on the finished steel structural components to ensure that they meet the design specifications and standards.
On-site installation: transport the made steel structural components to the construction site, and carry out on-site installation in accordance with the construction drawings. The installation process includes hoisting, calibration, welding, profiled steel plate installation, steel bar binding, concrete pouring and other steps.
Quality inspection: After the on-site installation is completed, the final quality inspection of the steel structure is also required to ensure that it is safe and reliable.
The above is the commonly used production method of steel structure, and its process covers multiple links such as design, material selection, processing, assembly, inspection, etc., to ensure that the final product can meet the needs of the project.
