In the warehousing and logistics field, riveted shelving is widely used in various scenarios due to its stable structure and high load-bearing capacity. Its core working principle lies in achieving rigid connections between components through riveting, forming an integrated force-bearing system, thereby ensuring the safety and stability of stored goods.
The main body of riveted shelving consists of uprights, beams, and shelves. These components are mechanically fixed using cold-forged metal rivets. During the riveting process, the rivet shank, under pressure, penetrates the through-hole of the connected component, and its end expands to form a bulge, tightly engaging with the hole wall, eliminating gaps and transmitting shear and tensile forces. This connection method differs from welding or bolting, forming an unremovable rigid node without the need for additional locking components, significantly reducing the risk of loosening due to vibration or load fluctuations.
From a mechanical perspective, the load-bearing capacity of the shelving depends on the combined effect of the vertical support of the uprights and the horizontal force transmission of the beams. The uprights primarily employ C- or Ω-shaped cross-sections to enhance bending resistance by increasing the moment of inertia. The beams are welded or riveted with hooks according to load distribution, engaging with the diamond-shaped holes in the uprights to achieve height adjustment. When goods are placed on the shelves, the load is evenly transferred from the shelves to the beams, then distributed to the uprights via the riveting points at both ends of the beams, ultimately borne by the ground foundation. The crucial role of the rivets in this process is to integrate discrete components into a continuous load-bearing structure, preventing deformation failure caused by localized stress concentration.
Furthermore, the sealing effect of the riveting process prevents air and moisture from intruding into the joint gaps, reducing the risk of metal oxidation and extending the shelf's lifespan. This design logic, balancing strength and durability, makes riveted shelving a preferred solution for medium to heavy-duty warehousing scenarios. Its working principle essentially involves optimizing material mechanics and connection processes to construct a reliable spatial load-bearing system.
