Five reinforcement methods for steel frame workshop

The steel frame workshop with a service life of over 20 years is relatively outdated in terms of both appearance and internal main structure. The replacement of color steel plates for external enclosures is relatively simple, and reinforcement measures need to be taken if the main structure is damaged or deformed and continues to be used. The following five methods are for reference:

First, methods of unloading and reinforcement

When the structural damage of the steel structure building itself is significant, unloading and reinforcement methods can be used. If the stress state of the structural join point becomes higher due to the damage of the plant structure, it is also necessary to temporarily reduce the load on the parts.

Second, methods of foundation reinforcement

The method of foundation reinforcement is mainly used for the structural failure of steel frame workshop or situations where the bearing capacity of the original section is too small. At this point, it is necessary to design a temporary support point for the steel structure to strengthen or update its support for the ground. Then completely unload the replaced steel structure equipment components. Of course, when replacing components, it is necessary to ensure the safety of the entire steel structure of the factory building.

Third, methods of load reinforcement

Compared with other reinforcement methods, the load reinforcement method is more convenient and economical in construction. This method is mainly used when the stress of the component is less than 80% of the strength of the steel structure or when the structural damage of the steel structure building is relatively small. In order to integrate the newly added firmware, temporary unloading measures need to be taken for the reinforcement rod.

Fourth, comprehensive reinforcement methods

The comprehensive reinforcement method is to strengthen the overall steel frame workshop, mainly including two methods: not changing the static calculation mode of the steel structure and changing the static mode of the steel structure. Adding or strengthening support systems is also an effective way to strengthen steel structure systems.

Fifth, methods of local reinforcement

The method of local reinforcement is a method used to strengthen the connection points of steel components or steel frame workshop with insufficient bearing capacity, mainly by increasing the cross-sectional area of steel bars in the steel structure and reducing the amount or length of steel bars.
