Due to the low cost of the steel structure plant, the construction period is short, the construction period is becoming more and more popular. Every year, a large number of steel structure factories are built up, but the steel structure plant also has limitations and durability. In particular, the steel structure plant from the 1990s to the period of the 1990s, and now there are two or 30 years of use history. Many steel structure components have experienced different degrees of rust loss, or the use function can no longer meet the status quo. The production capacity of production capacity is needed, especially in the fact that the structure of the plant is not enough, it is necessary to do stiffness and stability detection. If there is a disease in the detection of the steel structure component, the steel structure plant needs to be reinforced and reinforced.
The method of reinforcing the steel structure plant has reinforced loads, increased the cross section of the original structural component and connection intensity, prevent crack expansion, local reinforcement, comprehensive reinforcement, load reinforcement, load -reinforcing reinforcement, foundation of the foundation, foundation Reinforcement, etc., these are more commonly used methods for steel structure factories. Of course, the reinforcement methods of steel structure factories are diverse. The specific reinforcement method also needs to depend on customer choices and engineering companies’ suggestions. Starting according to actual. The following China Green Steel Structure Plant Reinforcement Company introduces 5 more common steel structure reinforcement methods:
1. Load enhancement
[ 123] The reinforcement of loading is a simpler reinforcement method, and it is also an economical method that saves costs. This method is mainly applicable to the component stress of the steel structure plant building less than 80%of the steel design or relatively mild component damage. In order to enable the new connocence to participate in the stress, it is necessary to take a temporary loading measure for the reinforcement rod. It is to temporarily uninstall the steel components so that the new steel component can participate in the stress.
2. Uninstallation of steel
The structure of the steel structure plant is severely damaged or the stress state of the component and connecting parts is very high. At the same time, the method of unloading steel bars is suitable for temporarily reduced loads.
3, the foundation reinforcement
This method is more suitable Happening. This foundation reinforcement method must set temporary supports on the ground for reinforcement or update. -Steel-Structure-MEASUREMENT
The structural safety of objects.
4. Partial reinforcement
The local reinforcement of theis to strengthen the components or connection nodes with insufficient bearing capacity, Including the method of increasing the section of the component, the method of reducing the freedom length of the component and the method of reinforcing the component.
5. Comprehensive reinforcement
Comprehensive reinforcement refers to the reinforcement of the overall structure of the. There are two reinforcements in total, one is the reinforcement method of static calculation diagram that does not change the structure, and the other is the reinforcement method of changing the static calculation diagram of the structure. At the same time, increasing or strengthening the support system is also a way to strengthen the steel structure workshop itself.
