Many people who use light warehouse shelves will complain that light storage shelves are too easy to damage and collapse, on the one hand, because of excessive load bearing of light storage shelves, on the other hand, they are not used correctly according to the push back racking system instructions. So how to prevent the deformation of lightweight storage shelves should be done?
1. The design aspect
a. When the storage shelf factory is designed, it should comprehensively and fully consider the factors such as the use environment, use requirements, load properties, material supply and installation conditions of the light storage shelf. Then the storage shelf manufacturer should choose a reasonable structural form, structural measures and production materials, so that the production of lightweight storage shelves technology is advanced, economical and reasonable, safe and applicable, to ensure quality.
b. The technical personnel of the storage shelf factory must make a precise analysis in theory when calculating the shelf data of the lightweight warehouse, and determine the parameters required in the design with the help of the corresponding test, and can also directly determine the bearing capacity of the shelf structure or a component through the test.
c. The settlement value of light storage shelves should be strictly controlled to ensure the normal use of the shelf structure. In the design, attention industrial racking systems should be paid to the separation of the shelf foundation and the building pillar foundation to prevent the damage of the building caused by the force of the shelf structure.
2. The installation method
a. Both ends of each beam must be equipped with locking devices, or screws and nuts are provided, so that the beam can be stably fixed on the column to prevent it from being separated by upward external forces. To ensure the bonding of the beam with its locking device (or screws and nuts), the normal operation of the beam lock or the tightening of the screw nut should be checked regularly during use, and the damaged device should be replaced in time.
b. The column foot should be correctly fixed on the concrete foundation. It is necessary to clarify whether the connection of the shelf to the ground is based on embedded parts, the secondary pouring scheme, or the scheme of direct connection between chemical bolts and the ground. The minimum size of the bolt in diameter must be determined by calculation based on actual loads, seismic loads or wind loads. Small Shenzhen shelves with manual feeding heavy duty metal racking below 2.4m can not be fixed. The concrete that fixes the foundation of the Shenzhen shelf column must be continuously cured for 28 days and withstand the corresponding pressure, and the uneven settlement of the foundation must meet the requirements of use.
3. Use
a. The user unit does not follow the operation instructions of the warehouse shelf factory in the process of use, and the actual weight of the goods exceeds the layer load of the shelf. If the weight of the goods placed in the process of using the shelf exceeds the layer load, it is easy to teardrop pallet racking cause deformation damage to the shelf.
b. The improper use of handling equipment hits the light storage shelf, especially the use of forklifts to operate the goods, due to the driver's wrong operation, it will lead to the forklift hitting the shelf, which will lead to the deformation of the light storage shelves.
c. In the process of use, if the light storage shelves are not evenly placed, the weight distribution is uneven, and it is easy to cause shelf deformation. For example, when placing goods, the weight of the goods is concentrated at one point, and there is no bearing in other areas, so the shelves are easily deformed.
