When designing the shelf, pay attention to the following points.metal utility cart with wheel

　　1. When designing the frame structure, we should comprehensively consider the requirements, equipment conditions, load properties, material supply and installation conditions, etc., and reasonably select structure forms, structural measures, and production materials quality.

　　2. The size of the shelves, deformation, and gaps shall meet relevant standards.

　　3. There are strict design procedures. When designing the frame structure in the durability limit or the large load limit state, the relevant standards must be met, and there must be calculation books. For major projects, it must be calculated by finite element to compound the strength, stiffness and stability of the shelves, and comprehensively assess the safety of the earthquake. For reused standard shelves, there must be a general calculation book.

　　4. The calculated data must be dependent or tested. Accurate analysis, bearing capacity of structure or component. Standard and inspection.

　　5. The beam -type shelves must be equipped with a locking device at both ends of each beam, or provide screws and nuts, so that the beam can be stably fixed on the column and the joint. The screw nuts are tightened and the damaged device is replaced in time.

　　6. The pillars of the shelves should be correctly fixed on the basis of concrete. Pieces, the secondary pouring scheme, small size, must be determined according to the actual load, earthquake load or wind load, and determine it by calculation.

　　7. The settlement value of the combined shelf shelf should be strictly controlled to ensure the normal use of the frame structure. The non -library shelves should pay attention to the separation of the shelves and the foundation of the building house column when designing.

　　8. One or more permanent signs must be set in the eye -catching part of the shelf. The area of each sign should not be less than (CM2). The sign should be marked with clear fonts. . The characteristics of light shelves and the characteristics of light shelves: 1 hole is used to connect the layer board; 2 3 4 drying and other process processing to assemble the finished product.
