Steel structure installation guidance with 3D animation
The installation of steel structures must follow a systematic process, which mainly includes the following steps:
Construction preparation: Complete the review of construction drawings, check the component models and sizes, build temporary supports and scaffolding, and ensure that the site is flat.
Foundation acceptance: Review the concrete foundation axis, elevation and embedded parts position to confirm that they meet the design requirements.
Component transportation and stacking: Use flatbed trucks for transportation, classify and stack, use wooden blocks to prevent deformation, and take rain protection measures.
Lifting operation: Use a crane to lift the main beam first and then the secondary beam, and adjust the positioning accuracy through the cable wind rope to avoid collision.
Measurement and correction: Use a total station and a level to monitor in real time, and adjust the verticality of the column and the horizontality of the beam through a jack or a hand winch to control the error within the allowable range.
Connection construction: High-strength bolt connections need to be initially tightened and re-tightened, and the welds are welded symmetrically to prevent deformation, and non-destructive testing is performed according to the specifications.
Inspection and acceptance: After installation, check the quality of the welds, the tightness of the bolts and the overall stability, conduct load tests and submit an acceptance report.
Key technical points: A special plan must be formulated for hoisting, and operations should be suspended when the wind speed exceeds level 6. Welding must control the interlayer temperature to avoid residual stress concentration. Bolt connections must use a torque wrench to ensure preload.
