Heavy-duty shelves are prepared and designed according to user attributes and needs, and it is critical to figure out the columns in the early stage. I think that everybody knows the value of pillars for carrying items on shelves. Excellent pillars can determine the outcomes of goods storage in a business. So, how to compute and determine the specs of heavy-duty racks? Listed below, shelves offer you a brief intro.
I. Strength and Instability Check
Since the pillar is the main force element of the rack, the structure is fairly made complex, and most of them utilize cold-formed thin-walled steel (the residual processing stress itself), and the load scenario is also more complex, especially for top-level racks with numerous layers and impacted The load is large, so that the style of the column bores, the check is complicated, and the fairness of the worth is directly related to the safety of the structure.
The hole type typically embraces inverted figure, rhombus or inverted trapezoid, so that the long hole of the column has a small angle with the vertical direction. After the hook is hung, it is instantly locked under the action of the gravity of the cargo, and the hook remains in surface area contact with the long hole of the column, The force is better, which makes sure more stable and safe usage.
Nevertheless, the opening of the hook hole has a fantastic influence on the bearing capacity of the short column of the column. The bearing capability after opening is 70% ~ 95% of the bearing capacity when the hole is not opened, and it has a higher influence on small-sized columns.
Therefore, under the property of satisfying the load carrying capability of the cross beam hook, the size and number of hook holes ought to be made as little as possible to improve the general load bring capacity of the rack. There are lots of long holes (hook holes) and storage-shelves round holes evenly dispersed on the front side of the column, which are utilized to hook the beams and install safety pins.
