double-span steel structure warehouse

What are the common reasons for reinforcing double span steel structure warehouses?

1. Accidents and natural disasters can cause severe damage to local structures.

2. The steel raw materials used do not meet the specifications.

3. After long-term use, the structure has suffered from varying degrees of rust, wear, and abnormal operation, resulting in structural defects and severe weakening of the structural components.

4. Due to the settlement of the foundation, it causes deformation and damage to the structure.

5. The change in production conditions results in the addition of structural loads, making the original structure unable to adapt.

6. Due to defects in the steel structure during planning or construction, the cross-section is weakened too much, and so on.

The painting of steel structures is a work that steel structure contracting units are prone to overlook, and it is also a weak link in steel structure engineering construction. If this phenomenon is not corrected, it will have a significant impact on the construction quality of steel structures, because the quality of rust removal and painting directly affects the maintenance costs of steel structures during their future use, as well as the service life, structural stability, and fire resistance time (to prevent fire painting) of steel structure engineering.

The root cause of this phenomenon lies in the insufficient understanding of the importance of painting work by the relevant personnel of the contracting unit, coupled with a lack of quality responsibility, and even a pursuit of profit, which often leads to problems in the quality of painting engineering in the later stage. Therefore, the supervising engineer needs to attach great importance to rust removal and painting work, and conduct strict inspection and acceptance of each process, which is the basis and determination of the quality of steel structure painting.
