majority Guangxi Heavy Shelf They are designed and produced according to customers' needs. It is important to determine the column before production. As we all know, the column is an important part of shelf z, which determines the weight that the shelf can bear and the goods stored. However, how to calculate the column price of specific heavy shelves?

1. Strength and inconsistency inspection

The column is the main force bearing part on our shelf. The structure and shape are complex. The columns are mostly cold-formed thin-walled steel (with certain processing stress), and the bearing conditions are relatively complex, especially for high-rise shelves. The more the load is, the more complicated the column design and check are. The fairness of the value is directly related to the safety of the structure.

2. Design inspection

The hole type is usually inverted splay, diamond or trapezoid, so that the long hole of the column forms a small included angle with the vertical direction. After the hook is hooked, it will automatically lock under the gravity of the cargo, and the hook will contact the long hole surface of the column, so that the force is better, more stable and safe. Use.

However, the opening of the hook hole has a great impact on the bearing capacity of the short column. The post hole bearing capacity is 70% - 95% of the non hole bearing capacity, which has a great impact on small columns. Therefore, on the premise of meeting the beam hook bearing capacity, the size and number of hook holes should be as small as possible to improve the overall bearing capacity of the shelf. There are many evenly distributed long holes (hook holes) and round holes on the front of the column, which are used to hook the crossbeam and install safety pins.

3、 Beam hook hole

From the perspective of cross section, there are many types of cross section shapes of columns, but from the perspective of current market distribution, the mainstream profiles are basically the basic types of stable shelves, and some profiles are relatively simple in structure. Structure, mainly used for light shelves; The multilateral rolling structure is more complex, and the processing technology is also more complex. It is mainly used for medium and heavy shelves.

Other shapes derived from the basic type mainly increase bending on the longer side to improve the stiffness and stability of the column. In the detailed design, in addition to strength, stiffness and structural integrity, the influence of the detailed forming process on the track shape and the influence of the blank pretreatment on the product quality should be generally considered, such as the influence of the bending deformation of the pre punched hole and non cold bending roll line on the product quality, and the possible deformation of the pre punched hole in the cold bending process.

Under the condition of ensuring the requirements of matching dimension tolerance and hole spacing, the design of sectional profiles shall consider the requirements of different plate thicknesses, and the deformation shall adopt a fixed bending radius.

4、 Column section shape

The column is also a force bearing part of the detachable shelf. Its design is the hub of the whole shelf system, which is directly related to the safety of the structure and the economy of use. Assembled shelves are mainly composed of basic parts such as columns and beams, and optional accessories such as corner protectors, floor corners, partitions, guardrails, laminates (steel plates or boards).

The column is the main load-bearing part of the shelf, bearing up to 21 tons. With the increase of shelf height and number of floors, columns bear heavy loads, and most of them are cold-formed and pressed thin-walled steel. There is a certain degree of processing stress in itself, and the actual stress is more complex. Therefore, the design of the column is the whole shelf. The hub of the system is directly related to the safety of the structure and the economy of use.

Heavy shelf is an important carrier to improve the efficiency of storage and retrieval in the warehouse, and it has been widely used in all walks of life. Removable rack is also called combined rack. The floor height can be adjusted according to the spacing, so that the shelf spacing can be adjusted according to the size of the goods placed, increasing the randomness and flexibility of the inventory. At the same time, it has a smaller component size and a warehouse. The advantages of high utilization rate, convenient production, interchangeable assembly, short installation cycle, etc Guangxi Shelf The shelf widely used in z.
