The steel structure platform is a multi-story (two to three stories or more) workbench constructed on an existing workshop or warehouse site, effectively doubling the usable space, with each floor capable of supporting 300-1500 kg. Goods are transported to the upper level via forklifts, lifting platforms, or conveyor belts, and then moved to their designated locations using hydraulic vehicles. The platform can also serve as an assembly line, assembly center, or storage space.
Similar to storage shelves, steel platforms typically feature a fully assembled structure, consisting of columns (H-shaped steel), main beams (H-shaped steel), secondary beams (H/C/M-shaped steel), floor slabs (steel plates), fences (square or round tubes), and stairs. The load-bearing capacity generally ranges from 500 kg to 800-1000 kg (for warehouse shelves).
When designing a steel platform, it is essential to consider the number of personnel, machinery weight, and production material weight. The design must facilitate operational processes while ensuring adequate space for movement. Generally, the net height of passageways should be at least 1.8 m, with a minimum width of 700 mm, and railings around the platform should be approximately 1 m high. For platforms over 2 m high, a ladder must be provided, with a width of at least 600 mm. The spacing between platform columns typically ranges from 3 to 5 m, not exceeding 6 m, and floor height can be tailored to workshop or warehouse needs. Additional factors to consider include:
1. Earthquake resistance level.
2. Platform height and load per square meter.
3. Stair placement (internal and external).
4. Lighting systems.
5. Goods retrieval methods: lift, forklift, or slide.
6. Other considerations such as drainage ditches and fire hydrants.
Advantages of steel structure platforms include:
1. Maximized warehouse space utilization, with the lower level for production and storage and the upper level for storage or office use.
2. Lightweight yet highly rigid structure, suitable for large spans and heavy loads, with materials exhibiting good plastic deformation and ductility.
3. Short construction time and low raw material costs, resulting in time and cost savings.
4. Fully assembled structure that can be disassembled and reassembled without damaging the factory floor.
Disadvantages include:
1. Heat-resistant but not fire-resistant; material properties change significantly above 250°C, and at 600°C, steel can no longer bear loads.
2. Poor corrosion resistance, making it susceptible to rust in humid or corrosive environments, necessitating regular maintenance.
3. Welding joints may develop cracks over time, leading to structural weaknesses.
