Sturdy shelves are planned and designed according to user qualities and needs, and it is crucial to determine the columns in the early stage. I believe that everyone understands the significance of pillars for carrying goods on shelves. Good pillars can determine the outcomes of products storage in an enterprise. So, how to calculate and determine the specifications of sturdy racks? Listed below, shelves give you a quick introduction.
I. Strength and Instability Check
Due to the fact that the pillar is the main force component of the rack, the structure is fairly complicated, and the majority of them utilize cold-formed thin-walled steel (the residual processing stress itself), and the load scenario is likewise more complicated, especially for top-level shelves with many layers and impacted The load is large, so that the design of the column bores, the check is made complex, and the fairness of the value is directly related to the security of the structure.
The hole type typically embraces inverted figure, rhombus or inverted trapezoid, so that the long hole of the column has a little angle with the vertical direction. After the hook is hung, it is automatically locked under the action of the gravity of the freight, and the hook is in surface area contact with the long hole of the column, The force is much better, which ensures more steady and safe use.
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 capability when the hole is not opened, and it has a higher impact on small-sized columns.
For that reason, under the premise of pleasing the load carrying capacity of the cross beam hook, the size and variety of hook holes should be made as little as possible to improve the total load bring capacity of the rack. There are many long holes (hook holes) and round holes equally storage-shelves distributed on the front side of the column, which are used to hook the beams and set up safety pins.
