Verify the size of components, welding quality, etc., to ensure that they meet the design requirements; When stacking, it is sorted according to the order of installation to avoid deformation.
When installing the steel structure, the following technical points need to be noted:
Component acceptance and stacking
Verify the size of components, welding quality, etc., to ensure that they meet the design requirements; When stacking, it is sorted according to the order of installation to avoid deformation.
Fundamentals & Positioning
The elevation and axis position of the top surface of the foundation should be accurate, and the verticality and plane position error should be guaranteed to be within the allowable range through embedded parts or bolt positioning.
Connection construction
Welding: control welding parameters, avoid cracks, porosity, important welds need to be detected;
Bolt connection: high-strength bolts are tightened according to the specified torque, and it is strictly forbidden to forcibly penetrate or leak screw.
Hoisting and calibration
The hoisting equipment is selected and adapted, and the components are firmly tied; After installation, the verticality and elevation should be corrected in time, and the temporary support should be stable.
Measurement and monitoring
The whole process is tracked and measured, the deviation data is recorded, and the adjustment is made in time when the limit is exceeded, and the stress monitoring is required for large structures.
Anti-corrosion and fire prevention
After the surface is derusted, the anti-corrosion coating is painted according to the requirements, and the thickness of the fireproof coating reaches the standard to avoid construction damage to the coating.
Safety & Environment
In bad weather (strong wind, rain and snow), it is necessary to suspend operations, set up protective measures for high-altitude operations, and temporarily use electricity in accordance with the specifications.
