Follow the principle of the shelf procedure:

1, consider the weight of the goods caused by the uneven distribution of deformation, transverse momentum stacker or forklift operation caused by seismic fortification intensity;

2, between the cargo, leaving shelves and between cargo and cargo piping and fire safe distance, leaving the fire sprinkler space;

3, high quality steel, surface rust and decorative treatment, under the premise to ensure shelf performance, minimize project cost.

We should also pay attention to the shelf design the following points:

1. Design shelf structure, you should consider factors requirements, equipment cases, load nature, material supply and installation conditions, a reasonable choice of structure, structural measures and the production of materials, so technologically advanced, economical, safe application, to ensure quality.

2. shelf dimensional tolerances, deformation and the gap should comply with the relevant standards.

3. Have a rigorous design process, both in durability limit state or to the maximum load limit state design shelf structure, we need to meet the relevant standards, to have calculations. For major projects must be finite element calculation of the shelf strength, stiffness and stability of the composite, for safety under earthquake conduct a comprehensive assessment. Standard shelf reusable, have a general-purpose computing book.

4. Calculate the data used must be evidence-based or get tested. Shelf structure is often difficult to make precise theoretical analysis must resort to the appropriate test to determine the parameters required for the design, but also directly determine the carrying capacity of the shelf structure or a member through tests. Test have reported test equipment should recognized by the state qualified calibration measurement sector, inspection.

5. beams shelves, both ends of each beam must be equipped with a locking device, or to provide screws and nuts that beam can be stably fixed on the column to prevent the upward force and detachment. To ensure that its beam engagement means (or screw and nut) are locked in use should regularly check the proper functioning of beam lock nut or screw fastening, timely replacement of damaged equipment.

6. Rack column column foot should be properly secured to the concrete foundation. To clear the shelves with the ground connection is to use embedded parts, using secondary irrigation scheme, or the use of chemical bolt directly connected with the ground plan. The diameter of the bolt, the minimum size of the embedded, must be based on the actual load, seismic load or wind load, determined by calculation. 2.4m the following materials on hand a small shelf may not be fixed. Fixed shelf column foundation of concrete must be cured 28 days in a row, and bear the appropriate pressure, uneven foundation settlement to meet the requirements.

7. The library shelf one Rack-based settlement value should be strictly controlled to ensure the normal use of the shelf structure. Non-library shelf one shelf shelves attention house foundation and building the basis of the separation column should be designed to prevent the shelf structure forces cause damage buildings.

8. striking at the shelf must be provided at one or more permanent signs, each sign of the area should not be less than 20 × 20 (cm2), it should be clearly marked maximum unit load fonts (kg) on the plate, each maximum Uniform load (kg), each cargo load cell allows the number of units stored.
