How to design safe warehouse racks

When designing warehouse rack structures, factors such as use requirements, equipment conditions, load properties, material supply and installation conditions should be comprehensively considered, and the structural form, construction measures and manufacturing materials should be reasonably selected to ensure advanced technology, economic rationality, safety and applicability, and quality. The dimensional tolerance, deformation and clearance of the warehouse racks should all comply with relevant standards.

There are strict design procedures. When designing warehouse rack structures for storage racks, whether in the durability limit state or the maximum load limit state, they must comply with relevant standards. For major projects, calculations must be performed to composite the strength, stiffness and stability of the racks, and a comprehensive assessment of safety under earthquakes. For standard warehouse racks that are reused, there must be a general calculation standard.

The data used in the calculation must be based on evidence or obtained through experiments. It is often difficult to make an accurate theoretical analysis of the warehouse rack structure. It is necessary to use corresponding tests to determine the parameters required in the design, or to directly determine the bearing capacity of the warehouse rack structure or a certain component through experiments. The test must have a report, and the test equipment should be calibrated and inspected by a qualified metrology department recognized by the state.

For beam pallet racks, both ends of each beam must be equipped with locking devices, or screws and nuts must be provided for fastening, so that the beam can be stably fixed on the column to prevent it from being separated by upward external force. To ensure the engagement of the beam with its locking device (or screws and nuts), the normal operation of the beam lock or the fastening of the screws and nuts should be checked regularly during use, and damaged devices should be replaced in time.

The warehouse rack columns should be properly fixed on the concrete foundation. It is necessary to clarify whether the warehouse rack is connected to the ground by embedded parts, secondary pouring scheme, or chemical bolts directly connected to the ground. The diameter of the bolts and the minimum embedding size must be determined by calculation based on the actual load, seismic load or wind load. Small racks with manual loading below 2.4m can be unfixed. The concrete of the fixed warehouse rack column foundation must be cured for 28 consecutive days and withstand the corresponding pressure, and the uneven settlement of the foundation must meet the use requirements.
