Steel structure projects are widely used in factories, warehouses, multi-story buildings, etc. If steel structure projects want to extend their service life, they must be inspected and maintained regularly. The maintenance and upkeep of steel structure projects generally begins one to three years after the completion of the project. The specific time point is mainly determined by the design service life of the steel structure project and the quality of construction and installation. For example, steel structure buildings are designed to have a service life of more than 50 years, and maintenance is generally performed every three years.
In fact, the cost of post-maintenance of steel structure buildings is relatively low, the frequency of maintenance is relatively small, the operation is simple, and the maintenance materials are not expensive. What are the main aspects of maintenance of steel structure buildings?
- Regular maintenance and upkeep. Depending on the type of building, service life, construction quality, etc., it is decided whether maintenance and upkeep should be performed once every one year, every two years or every three years. It is best to clean the exterior walls once a year. Be careful not to use sharp cleaning tools and use appropriate detergent. The branches, fallen leaves, stones, dust, etc. on the roof should be cleaned up in time every year to prevent the roof from collapsing due to excessive load.
- Regular anti-corrosion and anti-rust protection. Regularly check the steel surface for scratches, rust and damage, and repaint it in a timely manner. It is best to re-apply protective paint to all components in the steel structure building every three years. Pay attention to cleaning the dust, rust and other dirt in the steel structure before applying paint.
- For buildings with cranes, the crane equipment must be regularly inspected and maintained, and pressure vessels and other equipment must be cleaned at the same time.
- Regular deformation monitoring and maintenance: Structural changes to the building are not allowed without authorization. If the steel structure undergoes excessive deformation during use, it indicates that the load-bearing capacity or stability of the steel structure can no longer meet the needs of use, which is extremely dangerous. Relevant industry personnel should be organized in a timely manner to conduct inspections and repairs to prevent hidden dangers.
- Inspection of other details: Especially for welds, bolts, rivets and other joints, check whether there are cracks, looseness, breaks, etc. Check whether there is excessive local deformation of each rod, web, connecting plate and other components, and whether there is any damage. Check whether the wire tubes and wire troughs of all lines are damaged or aged to prevent the risk of electric leakage.
The maintenance and upkeep of steel structure buildings is not complicated, but it must not be ignored. By carefully following the above aspects, you can completely ensure and extend the service life of the building, and eliminate unnecessary safety hazards. Regular inspection and maintenance are very necessary for steel structure projects, not only to eliminate safety hazards, but also to keep the building clean and not aging.
