Construction points of steel supports
2025-07-28
Selection Control: Select appropriately sized steel supports based on the height, weight, wind pressure, and other pressures and loads of the structure to ensure they can support and safely transfer the building's weight and loads.
Design Control: Conduct precise structural and layout design, and reasonably arrange the position, direction, and quantity of support components to ensure compliance with design requirements.
Installation Control:
Before installation, carefully verify the quantity, size, and model of the support components to ensure they meet the requirements.
Installation should be performed by professional construction personnel, with safety protection measures in place to prevent accidents during installation.
Measurement Control:
After installation, measure the support points to ensure stability and accuracy.
Use professional measuring tools (such as laser trackers and theodolites) to obtain accurate data.
Regular measurements should be taken during construction, and the data should be used to analyze and correct the already constructed sections.
Connection and Reinforcement:
After installation, check the connection status of each node, and apply prestress after meeting the requirements.
Pre-applied axial force should be applied evenly, symmetrically, and in stages, and locked after the rated pressure stabilizes.
Reinforce the support nodes to ensure structural stability.
Prestress Application and Monitoring:
Monitor axial force during construction. If stress loss occurs due to temperature differences, self-deformation, etc., reapply prestress.
Reapply support prestress if prestress is lost or the wall undergoes horizontal displacement.
