Heavy-duty shelves are prepared and designed according to user attributes and needs, and it is vital to determine the columns in the early stage. I think that everyone understands the importance of pillars for bring goods on shelves. Excellent pillars can identify the outcomes of goods storage in a business. So, how to calculate and figure out the specifications of durable shelves? Below, racks provide you a quick introduction.
I. Strength and Instability Inspect
Because the pillar is the main force part of the shelf, the structure is relatively made complex, and most of them use cold-formed thin-walled steel (the recurring processing stress itself), and the load situation is likewise more complicated, specifically for top-level shelves with lots of layers and impacted The load is large, so that the style of the column bores, the check is complicated, and the fairness of the value is straight related to the safety of the structure.
Design check
The hole type generally adopts inverted figure, rhombus or inverted trapezoid, so that the long hole of the column has a small angle with the vertical instructions. After the hook is hung, it is immediately locked under the action of the gravity of the cargo, and the hook remains in surface contact with the long hole of the column, The force is much better, which guarantees more stable and safe usage.
Nevertheless, the opening of the hook hole has a great influence on the bearing capability of the short column of the column. The bearing capability after opening is 70% storage-shelves ~ 95% of the bearing capacity when the hole is not opened, and it has a higher effect on small-sized columns.
Therefore, under the facility of satisfying the load bring capacity of the cross beam hook, the size and variety of hook holes ought to be made as little as possible to improve the total load carrying capacity of the rack. There are many long holes (hook holes) and round holes equally distributed on the front side of the column, which are utilized to hook the beams and install safety pins.
