High-rise prefabricated storage steel structures, often used in the construction of apartments, hotels, warehouses, and workshops, are designed to offer robustness, efficiency, and flexibility. Here’s a detailed look at how these structures are fabricated, focusing on frame truss fabrication and welding techniques:
1. Design and Engineering
- Customization: Each structure is designed based on specific client requirements, including dimensions, load-bearing capacities, and architectural aesthetics.
- CAD Software: Computer-Aided Design (CAD) software is used to create detailed plans and blueprints, ensuring accuracy and precision.
2. Material Selection
- High-Strength Steel: Typically, high-tensile steel is chosen for its strength-to-weight ratio, which is crucial for supporting heavy loads and resisting environmental stresses.
- Corrosion Resistant: Galvanized or coated steels are selected to resist corrosion, enhancing durability and extending the structure's lifespan.
3. Fabrication Process
- Cutting and Shaping: Steel beams and plates are cut to size using plasma cutting or laser cutting machines for precise dimensions.
- Bending and Rolling: Large beams may require bending and rolling to form curves or angles, depending on the design specifications.
4. Truss Fabrication
- Component Assembly: Trusses are assembled by connecting steel members (chords, webs) using bolts or welding.
- Quality Assurance: Each component undergoes rigorous quality checks to ensure it meets structural integrity standards.
5. Welding Techniques
- MIG (Metal Inert Gas) Welding: Commonly used for its speed and ability to weld thinner sections.
- TIG (Tungsten Inert Gas) Welding: Preferred for its precision, especially in critical joints where high strength is required.
- Arc Welding: Used for thicker sections and offers a strong bond between steel pieces.
6. Painting and Coating
- Primer Application: A primer is applied to prevent rust and improve paint adhesion.
- Finish Coating: A protective coating is added to shield the steel from environmental elements and enhance appearance.
7. Assembly and Erection
- Prefabrication: Components are pre-assembled in a factory setting, ensuring precision and quality control.
- On-Site Erection: Once transported to the construction site, the structures are erected using cranes and specialized lifting equipment.
8. Inspection and Testing
- Non-Destructive Testing (NDT): Techniques like ultrasonic testing and magnetic particle inspection are used to detect any flaws in the welds.
- Load Testing: Structures undergo load tests to verify their strength and stability under operational conditions.
9. Integration with Other Systems
- Electrical and Plumbing: Prefab structures can easily integrate electrical wiring and plumbing systems, facilitated by the modular design.
- HVAC Systems: Heating, ventilation, and air conditioning systems can be efficiently installed, optimizing energy usage.
