Hui Xing Container House Maintenance

The maintenance of Hui Xing container houses should be carried out from multiple aspects such as structure, anti-corrosion, roof and wall, drainage, doors and windows, load and lightning protection, auxiliary components, and daily environmental safety. Details are as follows:

• Main structure maintenance: Regularly inspect steel columns, steel beams, and purlins for deformation, bending, and weld cracks. Tighten loose bolts and check for rust and detachment of high-strength bolts. Observe the settlement and tilt of the factory building, and stop work immediately for inspection if any abnormalities are found. Check the integrity of supports, tie rods, and tie bars to prevent missing or loose parts.
• Anti-corrosion and rust prevention maintenance: Promptly remove rust and repaint areas where the paint has peeled off or rust has formed. Conduct annual inspection and coating. The bottom of beams and columns, splice joints, and dead corners where water accumulates are key areas for rust prevention. In humid factory areas, increase the frequency of rust prevention to avoid large-scale rusting of steel.
• Roof and wall maintenance: Check for damage, edge curling, and water leakage in color-coated steel sheets, and promptly seal and repair them. Clean leaves, debris, and snow from the roof to prevent excessive load. Seal the waterproof rubber strips at the ridge, gutter, and expansion joints to prevent water leakage. Check and tighten the rivets and edge sealing parts of the wall panels.
• Drainage system maintenance: Regularly dredge gutters and downspouts to prevent blockage and water accumulation. Check the drainage slope to avoid water accumulation on the roof that could corrode the panels. Conduct a comprehensive inspection of drainage fittings before the rainy season.
• Door and window maintenance: Ensure that steel doors and sliding doors open and close smoothly, and inspect hinges and locks. Replace aging window frame sealants in a timely manner to prevent wind, rain, and water infiltration. Clean debris from ventilation louvers to ensure ventilation and heat dissipation.
• Roof load and lightning protection: It is strictly prohibited to stack heavy objects or add suspended equipment without permission. Annually test the connection firmness of the lightning protection grounding and lightning strips to ensure that the grounding resistance meets the standards and eliminate lightning strike safety hazards.
• Auxiliary component maintenance: Inspect crane beams and crane rails, and replace them promptly if the wear exceeds the standard. Check that guardrails, ladders, and platform踏板 (platform tread plates) are not loose or broken. Ensure that fire protection brackets and pipeline brackets are stable and not deformed.
• Daily environment and safety: Keep the factory building damp-proof and well-ventilated to reduce water vapor corrosion of steel. It is strictly prohibited to bake steel structures with open flames at close range. Divide load-bearing areas and do not stack goods beyond the designed load. Conduct a comprehensive overall inspection before and after typhoons and heavy snowfalls.
