The service life of steel structure buildings is more than 50 years. The roof and wall panels of prefabricated steel…
For the logistics park, the logistics warehouse design is an essential part of its planning and design. The success of the logistics warehouse architectural design directly affects the logistics park’s function and its operational efficiency.
Logistics warehouse design
The function of the warehouse building structure
Mainly include the building’s structure selection, the building’s ceiling height; the number and area of the building; the choice of the ground; the size of the passage.
The form of the warehouse building
Through the construction of building space, the functional partitions will not interfere with each other, laying a foundation for better use of the functional space; through the design of indoor and outdoor environmental space of the building, improve the quality of the building itself, and use clever design techniques to highlight the style design of the building Wait.
Warehouse building technology
It includes the energy-saving design of buildings, the use of materials, etc.
1. Logistics warehouse structure type
A building structure is a skeleton composed of essential components such as beams, slabs, walls, columns, foundations, etc., which can bear and transmit loads and other insights according to specific composition rules and correct connection methods. There are many classification methods for building structures, which can generally be classified according to the structure’s materials, load-bearing structure, the use function, the appearance characteristics, and the construction method. Here we mainly introduce the classification by material.
Buildings can be divided into four categories according to the materials used: concrete structure, steel structure warehouse, masonry structure, and wood structure. With the rapid development of the logistics industry, the current logistics mainly use steel and concrete structures.
1) Steel structure warehouse building
The steel structure is a structure formed by effective linking of steel plates, section steel, etc., and is widely used in industrial buildings and high-rise buildings. With the rapid development of economic construction and the substantial increase in steel output in China, the application of steel structures has been greatly expanded. Compared with other structural forms, steel structure has the main advantages of high strength, lightweight, uniform material, good reliability, simple construction, short construction period, and good seismic performance.
The steel structure has certain advantages in terms of structural performance, use function, and economic benefits. In the steel structure, the portal frame steel structure warehouse is the most popular. Generally, the span is between 18 and 36 meters, and this range can be exceeded if necessary.
2) Concrete structure
Concrete structures include reinforced concrete structures, and prestressed concrete structures, among which reinforced concrete structures are the most widely used. Its main advantages are high strength, good integrity, durability and fire resistance, easy to obtain materials on site, and good moldability. The main disadvantages are self-heavy weight, poor crack resistance, multiple construction links, and a long construction period.
2. Logistics warehouse design for height
The height of the warehouse refers to the distance from the ground to the roof. In theory, the higher the warehouse’s height, the better, but in fact, the higher the warehouse will increase the construction cost and reduce the number of floors of the building. The warehouse’s height is mainly affected by the average height of the stack of goods, the type of storage equipment, and the type of stacking equipment.
1) Average height of cargo stacking
The stack’s average height refers to the average height of the goods stacked on the actual floor space of the stack. The average height of the warehouse is directly proportional to the utilization rate of the warehouse height. The higher the warehouse’s average height, the higher the warehouse height utilization rate, and the higher the warehouse height.
2) Types of storage devices
When the warehouse has an automatic three-dimensional warehouse, the height is often high; when the warehouse mainly uses pallet stacking, the warehouse’s height is often relatively low. An effective height design must be able to meet the basic height requirements of the storage device used. Simultaneously, storage equipment should be kept at a certain distance from the warehouse roof and beams to ensure fire protection and ventilation.
3) Types of stacking equipment
Different operating equipment also has different requirements for the height of the warehouse. Generally speaking, the distance from the ground to the beam required by forklifts is relatively low, while the distance required by large cranes (such as gantry cranes, bridge cranes, etc.) is relatively high.
Generally speaking, the net height of a single-story elevated warehouse should not be less than 7 meters. If a portal steel frame structure is used, the net height should be 8-10 meters.
3. Logistics warehouse design for floors and area
Warehouses can be classified into single-story warehouses and multi-story warehouses according to the number of floors. The number of floors is related to the warehouse’s structure and related to the height of the warehouse. It is generally believed that the higher the warehouse is, there are fewer floors; the lower the warehouse can appropriately increase the number of floors
The determination of the warehouse area involves the length and width of the warehouse. The warehouse’s length and width are affected by factors such as the type of goods stored, the handling method, and the selection of building structure. Generally, a rectangle is used, and the length is about 3 times the width.
