As a crucial component of warehousing systems, combining strength and economy, riveted shelving is constructed using modular design and reliable mechanical connections. Its overall functionality is achieved through scientific selection and precise assembly.
The main frame consists of three core components: uprights, beams, and shelves. Uprights are typically made of cold-rolled steel sheet, roll-formed, with C-shaped or Ω-shaped cross-sections to enhance bending stiffness. The diamond-shaped holes on the surface facilitate beam positioning and allow for adjustable shelf heights to accommodate diverse storage needs. Beams utilize rectangular steel tubing or double-C-shaped interlocking beams, with pre-set hanging plates or hooks at both ends for snap-fit positioning with the upright holes, providing a stable reference for subsequent riveting. Shelves can be made of steel plate, wood, or grating, with thickness and material matched to load-bearing capacity to ensure uniform planar load distribution.
The assembly process follows the sequence of "erecting the frame first, then connecting the beams, and finally securing the shelves." First, the uprights are vertically fixed to the ground at the designed spacing, and the verticality is calibrated using a level. Then, the crossbeams are inserted into the diamond-shaped holes in the uprights, and the hanging plates are manually or with simple tools brought into contact with the inside of the uprights to form initial positioning. The crucial riveting step requires the use of solid rivets with a diameter matching the hole position. Using a riveting machine or manual riveting gun, pressure is applied so that the rivet shank penetrates the through-hole in the hanging plate and the upright, and then expands at the end to form a rigid, two-way locking joint. This step requires careful control of the riveting force to avoid deformation of the sheet metal due to excessive pressure or loosening of the connection due to insufficient pressure. Finally, the shelves are laid and secured to the crossbeams with bolts or clips to complete the overall assembly.
The core of this method is replacing traditional bolt connections with riveting, eliminating the need for nut locking, and leveraging the interchangeability of modular components to achieve rapid installation and subsequent maintenance. Through the precise fit of structural components and the irreversibility of mechanical connections, riveted shelving significantly improves the construction efficiency and long-term stability of the storage system while ensuring load-bearing strength.
