With industrial upgrading and the increasing age of factory buildings, many old industrial plants face aging steel structures, insufficient load-bearing capacity, and even safety hazards. Through scientific and reasonable steel structure reinforcement and renovation, not only can the load-bearing capacity of the plant be restored, but its service life can also be significantly extended, improving production efficiency. This article will analyze in detail the methods, construction steps, and precautions for reinforcing the steel structures of old industrial plants, helping enterprises achieve safe and reliable renovation and upgrading.
Steel Structure Reinforcement and Renovation of Old Industrial Plants
Common Steel Structure Reinforcement Techniques
1. Steel Plate Bonding Reinforcement Method: High-strength steel plates are bonded to the surface of load-bearing components to quickly improve load-bearing capacity.
Advantages: Short construction period, minimal interference with the original structure.
Applicable Scope: Local reinforcement of bending or shear members such as beams, columns, and trusses.
2. External Steel Wrapping Reinforcement Method: Steel plates or structural steel are wrapped around the outside of old beams and columns and fixed with bolts or welding.
Advantages: Significantly improved load-bearing capacity, enhanced overall structural stability.
Applicable Scope: Main beams and load-bearing columns bearing heavy loads.
3. Carbon Fiber Reinforced Polymer (CFRP) Reinforcement: Laying high-strength carbon fiber fabric or sheets improves the bending and shear resistance of components.
Advantages: Lightweight, high-strength, corrosion-resistant, minimal impact on the interior of the factory building during construction.
Applicable Scope: Components with localized weak loads or where external steel cladding is difficult.
4. Enlarging Cross-Section or Support System Reinforcement: Adding steel beams, supports, or thickening the cross-section of existing components to distribute the structural load.
Advantages: Systematically improves the overall structural stability.
Applicable Scope: Overall structural renovation of the factory building, or future equipment load increases.
Steel Structure Reinforcement Construction Steps
1. Structural Inspection and Assessment
Using ultrasonic testing, magnetic particle testing, and other techniques to inspect steel for corrosion and cracks.
