Attic shelf
The overall structure of the attic shelf is assembled. Usually, medium-sized shelves or heavy-duty shelves are used as the main support and the floor panel (which shelf is selected according to the total load weight of the shelf unit). The floor panel usually adopts special floor panels such as cold-rolled steel floor panels, checkered steel floor panels or steel grid floor panels. The floor panels adopt mutual buckle structure without on-site welding, and the overall appearance and generosity. Compared with the concrete structure or steel structure, because the ground floor shelf itself plays the supporting role of the upper floor, it has the advantages of low cost and high space utilization.
In recent years, the use of cold-rolled steel floor loft-type shelves, it has a strong bearing capacity, good integrity, bearing uniformity, high precision, smooth surface, easy to lock and other advantages. There are many types of optional, and easy to match the lighting system, access, management are more convenient. The load capacity of each layer of unit shelves is usually within 500kg, the floor spacing is usually 2.2m ~ 2.7m, and the height of the top shelf is generally about 2m, taking full account of the convenience of staff operation.
The attic shelf panel has flat plate, patterned steel plate, punched steel plate and other varieties to meet the different requirements of fire prevention, ventilation, light and so on. The goods are usually delivered to the second floor and the third floor by forklift, hydraulic lift platform or freight ladder, and then delivered to a certain location by light trolley or hydraulic pallet truck.
Attic shelves usually have a bearing capacity of 300KG ~ 1000KG/m2, and the columns are circular tubes with strong bearing capacity and less steel use. The primary and secondary beams can be selected according to the bearing requirements of H-shaped steel and C- shaped cold-formed beams of special steel platforms, which are currently more economical and reasonable in steel structure engineering. Carry out overall planning according to customer requirements, calculate the strength and rigidity of the platform, and set up safety barriers around it.
The attic shelf floor panel adopts special C- shaped cold-formed patterned steel plate or hollow plate, adopts buckle plate structure, and is rigidly fixed with primary and secondary beams. The whole platform structure has strong integrity. Different floor panels can be selected according to actual needs to meet the requirements of fire fighting, dust prevention and small falling prevention. The lighting system can also be configured under the floor as required.
Loft shelves are widely used in the case of high warehouse, small goods, manual access and large storage capacity, which can make full use of space and save warehouse area. According to the actual site and specific requirements, it can be designed as a single-layer or multi-layer attic, generally 2-3 layers. It is especially suitable for the classification and preservation of series products of enterprises such as auto parts and electronic devices, with a load of ≤ 500kg/layer.
Features of attic shelves:
1. The surface is treated with electrostatic powder spraying, with beautiful appearance and generous structure.
2, usually 2-3 floors, set up stairs and cargo lift elevators.
3, column, main beam, auxiliary beam material cross-section optimization, strong bearing capacity.
4, attic shelf fully assembled structure, free combination, installation, disassembly convenient and flexible.
5, according to the actual site needs, flexible design into two or more shelves, make full use of storage height, better use of storage space.
6. Attic shelves fully consider humanized logistics, beautiful design and generous structure. It is easy to install and disassemble, and can be flexibly designed according to the field.
7. The lower layer of the attic shelf is a shelf form, and the upper layer can be a platform or a shelf structure. The bottom shelf can store materials and support the floor, which is very flexible.
8. The floor of attic shelf is paved with special floor slab for shelf. Compared with patterned steel plate or rigid grid, it has the characteristics of strong layer load capacity, good integrity, uniform layer load, smooth surface, easy locking, etc.
9, suitable for high warehouse, small goods, manual access, large storage capacity.
