Strength calculation and design of AS/RS shelf
(AS/RS) is a modern logistics center of main equipment and facilities. The main structure is a high shelf unit cell structure. Typically made with steel or reinforced concrete. Steel shelves have components small size, high utilization rate of warehouse, production and installation advantages, and became more and more users and logistics equipment company of choice. Steel shelves can be made of cold rolled steel, hot-rolled angle bars or beam welded together, usually height of the shelve is between 8-50m. Lattice structure and size of the goods by goods stored by State and size to determine. In order to ensure the shelves have sufficient strength and stability, especially in extreme cases, for example in the earthquake caused by the short-term under alternate horizontal dynamic load, shelf column, base, lift rod and strength calculation of the connecting plate has become essential in the design of the shelves. This paper by design case, taking into account the long-term static load, short-term changes in load conditions proposed shelf post, lift rod, Foundation and strength calculation and design methods of connecting plate. 1 basic parameter settings
Set tray for standard sizes: 800xl000x800 (mm) and pallet stacking load averages 8kN, maximum value of 10kN; shelf Board size is 1175mm, the exhaust direction columns spacing is 850mm, prop 75x75 mm2 cross section dimensions. Weight of the shelf is 500N. Unit ground distance from Ht,H2, respectively, ... Hs。 Under the Japan industrial machinery Association prepared by the split rack structure standards for long-term stress, normal state, its shelves full ratio 100%; for short-term stress, during an earthquake, its shelves full rate is 80%.
