The connection between the carrying capacity of the storage rack and the column

The emergence of the column butterfly hole pattern reduces the process of installing screws to connect the shelves, which makes the storage shelf structure simpler. Because there are many holes in the shelf, the height can be adjusted freely. Such storage shelves are very convenient to use. The rack hole pattern is designed to meet the requirements of dimensional tolerance and hole spacing.
At present, the common shelf holes in the market generally have diamond holes, some have round holes at the same time, and some do not. The design of the round hole is to increase the convenience of connection. For high-rise shelves or shelves with very large carrying capacity, the absence of round holes can slightly increase the carrying capacity of the column. The original design of this type of pass comes from abroad and has been used for more than 20 years. There has never been a report on bearing problems. Some are butterfly holes, some are tongue holes, some are inverted eight-shaped holes, and some are rivets.

Is there any connection between the carrying capacity of the shelf and the shelf column? According to the introduction of the Spieth Shelf Factory, the size of the column card has a great relationship with the actual carrying capacity. Theoretically, due to the larger size of the column card, the connection between the beam and the column will be different. The hinged structure and the fixed structure play the greatest role in the bearing capacity of the beam.

Is there a big difference in the carrying capacity of storage shelves with different holes? If other structures are the same, the difference in carrying capacity is actually very small, almost negligible. However, different hole designs are different in terms of cost, ease of installation and stability. For example, the diamond-shaped hole is matched with the reinforced column clamp. When the rack is loaded, the column clamp and the column will be compressed, which can effectively prevent the rack from shaking. But for installation, it may increase the installation cost a little.
