1. The space and floor height separated by mezzanine should meet the use function;
2. The main materials of steel structure interlayer (generally, the practice of large-scale interlayer is cast-in-place concrete after H-beam profiled steel plate pavement), the use model of H-steel, the thickness and specification of embedded parts, and the specification and quantity of high-strength bolts shall comply with the steel structure design specifications;
3. If it is a small mezzanine, the general material is square tube and angle steel, which should also meet the overall stress requirements. The calculation method also refers to the steel structure design code;
4. Its overall weight should be within the stress range of the main beam or the main frame, which will not affect the main structure.
