beam type shelf design need to comply with what principles?

The first prerequisite for designing a beam shelf must know the size of the shelf, the number of layers, the size of the tray, and the size of the product.

In addition, in the comprehensive design of the shelf also need to pay attention to the following principles:

1. There is a safe distance between goods, between goods and shelves, and between goods and fire pipes, leaving fire sprinkler space;

2, the selection of high-quality steel, Henglida Logistics Equipment Co., Ltd. choose Q235D, its low temperature resistance and toughness are very good, surface rust and decorative treatment, to ensure that the shelf performance under the premise of minimizing the cost of the project.

3, considering the deformation caused by the uneven distribution of the weight of the goods, the lateral impulse caused by the action of the stacker or forklift, and the seismic intensity fortification;

4. The dimensional tolerance, deformation and clearance of the shelf shall conform to the relevant standards.

5 has a strict design procedure, whether in the durability limit state or the maximum load limit state design shelf structure, must meet the relevant standards, to have a calculation. For major projects, finite element calculations must be carried out to compound the strength, stiffness and stability of the shelf, and to conduct a comprehensive assessment of the safety under the action of earthquakes. For standard shelves that are reused, there must be a general calculation book.

6 The data used in the calculation must be based on evidence or experimental results. Shelf structure is often difficult to make accurate analysis in theory, we must use the corresponding test to determine the parameters required in the design, but also directly through the test to determine the shelf structure or a component carrying capacity. The test shall be reported, and the test equipment shall be calibrated and inspected by the qualified metrology department recognized by the state.

7 beam type shelves, each beam must be equipped with a locking device at both ends, or provide screws and nuts fastening, so that the beam can be stably fixed on the column, to prevent the upward force and from being separated. To ensure the engagement of the beam with its locking device (or screw and nut), the normal operation of the beam lock or the tightening of the screw and nut should be checked regularly during use, and the damaged device should be replaced in time.

8 When designing the shelf structure, the use requirements, equipment, load properties, material supply and installation conditions should be comprehensively considered, and the structural form, structural measures and production materials should be reasonably selected to achieve advanced technology, reasonable economy, safety and application, and ensure quality.
