1. The scale, service deformation and gap of the shelf shall comply with relevant specifications.
2、 Stereoscopic library The settlement value of the bottom of the storage rack shall be strictly controlled to ensure the normal operation of the rack structure. In the planning of non warehouse shelves, attention should be paid to the separation between the bottom of the shelf and the bottom of the building roof column to prevent the damage of the building caused by the effective force of the shelf structure.
3. When planning the shelf structure, factors such as application requirements, equipment conditions, load properties, data supply and installation conditions should be summarized and considered, and the structural mode, structural measures and manufacturing data should be reasonably selected to achieve advanced technology, reasonable economy, safe application and quality assurance.
4. There are strict planning procedures. When planning the shelf structure, whether in the durability limit state or in the heavy load limit state, it should comply with the relevant specifications, and there should be an accounting book. For major projects, it is necessary to conduct finite element calculation, compound the strength, stiffness and stability of the shelf, and comprehensively check the safety under the earthquake effect. For the standard shelf that is reused, there should be a general accounting statement.
5、 Pallet Racks It is necessary to equip locking equipment at both ends of each beam, or provide screws and nuts 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 connection between the beam and its locking equipment (or screws and nuts), check the normal operation of the beam lock or the fastening of the screws and nuts regularly during the use, and replace the damaged equipment in time.
6. The plinth of rack column shall be correctly fixed on the concrete foundation. It should be clear that the connection mode between the shelf and the ground is to select embedded parts, secondary irrigation scheme, or direct connection between chemical bolts and the ground. The diameter of bolt | embedded Z small scale, it is necessary to check and confirm according to the practical load | seismic load or wind load. Small shelves with manual loading below 2.4m may not be fixed. It is necessary for the concrete fixing the bottom of the rack column to be cured for 28 days continuously, and to accept the corresponding pressure. The uneven settlement of the bottom must meet the application requirements.
7. The data selected for accounting must be based on evidence or obtained through experiments. It is often difficult to make an accurate analysis of the shelf structure in theory. It is necessary to confirm the parameters required in the planning with the help of corresponding experiments, or directly confirm the bearing capacity of the shelf structure or a component through experiments.
