Technical Key Points for Reinforcement of Prefabricated Industrial Steel Structure Warehouse in Framework Light Metal Building

1. Steel structures can be reinforced locally or comprehensively based on the extent of damage. Common methods include changing the calculation pattern, increasing the cross-section of the original structural components, adding support points, welding, and bonding external steel. Among them, strengthening the support system reinforcement method is one of the effective methods.

2. The method of changing the calculation graphics for reinforcement refers to the use of measures such as changing the load distribution, transmission path, node properties, and boundary conditions, adding additional members and supports, applying prestressing, and considering spatial collaborative work to reinforce the structure.

3. The bonding reinforcement method uses structural adhesive to stick steel plates to the areas that need to be reinforced, and relies on structural adhesive to bond them together under common stress, improving the load-bearing capacity of the structure. Advantages of adhesive reinforcement: After reinforcement, it basically does not increase the self weight of the original structure and the size of the original components; Easy to operate, low cost, high efficiency, and can be used for construction in narrow spaces, making it particularly suitable for on-site repairs; There is no open flame during the construction process, suitable for various special environments.

4. The method of adding support points for reinforcement is applicable to the reinforcement of structures such as beams, slabs, trusses, and grid structures. This method can be divided into two types based on the different stress performance of the supporting structure: rigid support point reinforcement method and elastic support point reinforcement method.

5. Enlarged section reinforcement method: a reinforcement method that increases the cross-sectional area of a concrete structure or structure to enhance its load-bearing capacity and meet normal use. It can be widely used for the reinforcement of beams, slabs, columns and other components of concrete structures, as well as general structures.
