The most suitable steel structure for reinforcement in prefabricated steel workshops
If the prefabricated steel workshops have been used for a long time or caused some structural damage due to improper use, steel structures can be used to reinforce it to ensure the stability of the original structure. The steel structure has high strength and strong plasticity, and the reinforcement scheme can be customized according to the site. It is safe and effective to carry out reasonable steel structure reinforcement for the weak steel structure workshop factory. There are several methods:
1. The local reinforcement method is a method used to strengthen steel members with insufficient bearing capacity or the connection points of prefabricated steel workshops. It mainly increases the cross-section of steel bars in the steel structure and reduces the amount of steel bars or the length of steel bars.
2. The method of comprehensive reinforcement is to strengthen the overall steel structure workshop factory, mainly including two methods of not changing the static calculation mode of the steel structure and changing the static mode of the steel structure. Adding or strengthening the bracing system is also an effective way to strengthen the steel structure system.
3. Compared with other reinforcement methods, the load reinforcement method is more convenient for construction, more economical and practical. This method is mainly used when the component stress is less than 80% of the steel structure strength or the structural damage of the steel structure building is relatively small. In order to integrate the newly added firmware, it is necessary to temporarily unload the reinforcing rod.
4. When the structural damage of the steel structure building itself is large, the method of unloading reinforcement can be used, and if the stress state of the structural connection points becomes higher due to the damage of the steel structure in the workshop, it is also necessary to temporarily reduce the stress on the parts. load.
5. The method of foundation reinforcement is mainly used for the structural damage of the prefabricated steel workshops or the situation where the bearing capacity of the original section is too small. At this time, it is necessary to design a temporary support point for the steel structure to strengthen or update the support of the steel structure to the ground. Then completely unload the replaced steel structural equipment components. Of course, the safety of the entire prefabricated steel workshop structure must be ensured when replacing components.
