Durable racks are prepared and developed according to user qualities and needs, and it is critical to determine the columns in the early stage. I think that everybody understands the significance of pillars for carrying goods on racks. Excellent pillars can identify the results of goods storage in an enterprise. So, how to calculate and figure out the requirements of durable shelves? Below, racks offer you a short introduction.
I. Strength and Instability Check
Because the pillar is the primary force element of the shelf, the structure is relatively made complex, and the majority of them use cold-formed thin-walled steel (the residual processing tension itself), and the load circumstance is also more complex, particularly for high-level racks with lots of 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 straight related to the security of the structure.
The hole type usually 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 storage-shelves is hung, it is automatically locked under the action of the gravity of the freight, 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 a fantastic influence on the bearing capability of the short 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 greater influence 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 ought to be made as little as possible to enhance the overall load bring capacity of the rack. There are numerous long holes (hook holes) and round holes evenly dispersed on the front side of the column, which are used to hook the beams and set up safety pins.
