Sturdy racks are planned and created according to user qualities and requirements, and it is crucial to figure out the columns in the early stage. I believe that everybody knows the value of pillars for carrying products on shelves. Great pillars can determine the results of items storage in an enterprise. So, how to compute and determine the requirements of heavy-duty racks? Below, shelves offer you a short intro.
I. Strength and Instability Check
Due to the fact that the pillar is the main force element of the shelf, the structure is fairly made complex, and most of them utilize cold-formed thin-walled steel (the residual processing tension 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 is tedious, the check is complicated, and the fairness of the worth is directly related to the security of the structure.
The storage-shelves 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 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.
However, the opening of the hook hole has an excellent effect on the bearing capacity of the brief column of the column. The bearing capacity after opening is 70% ~ 95% of the bearing capacity when the hole is not opened, and it has a higher impact on small-sized columns.
For that reason, under the premise of satisfying the load bring capacity of the cross beam hook, the size and number of hook holes need to be made as small as possible to enhance the total load carrying capability of the rack. There are many long holes (hook holes) and round holes uniformly dispersed on the front side of the column, which are used to hook the beams and set up safety pins.
