Havit Steel designed the Chile Steel Structure Warehouse; the Chile Steel Structure Warehouse size is 20 meters (width) x 35…
The mezzanine can be used in large-space buildings and taller warehouses. It is a common way to separate the upper and lower floors and increase the warehouse’s use areas. It can be used as a platform or as an office. The main structure of the Steel structure warehouse mezzanine uses Q345B H-shaped steel. The main structure should lay with steel floor slabs and then reinforced concrete with a thickness of 120-200 mm.
The type of Steel structure warehouse mezzanine
1. Steel structure frame and wooden board combination
The structural solution has the advantages of low cost, lightweight, and short construction period. Still, the sound insulation effect is not ideal, the board deformed for a long time, the load is small, and the fire, insect and mildew resistance is weak. It is suitable for small span buildings.
2.Steel structure and lightweight floorboard combination
This structural combination scheme has safety and environmental protection, lightweight, high strength, long-term non-deformation, fast construction, short construction period, and installed at the same height as the upper flange of the steel beam during installation.
3.Steel structure frame, floor bearing deck, cast-in-situ concrete combination
This scheme has the characteristics of high safety performance, large load, no chattering, and excellent sound insulation. It is suitable for steel structure warehouse buildings with different large and small spans, or large spans Industrial workshop buildings, etc.
The detail of floor bearing deck
The floor bearing deck, also known as a steel bearing plate or building pressed steel plate, is formed by a cold-forming galvanized steel plate by rolling. Its cross-section becomes V-shaped, U-shaped, trapezoidal, or similar shapes of waveforms, mainly used as permanent formwork.
The floor bearing plate is used as the tensile reinforcement of the concrete floor slab, which also improves the floor slab’s stiffness and saves the amount of reinforcement and concrete.
The surface embossing of the pressed plate makes the maximum bonding force between the floor bearing plate and concrete so that the two form a whole, with stiffening ribs, so that the floor bearing plate system has a high bearing capacity.
It can give full play to the advantages of steel tensile and concrete compressive performance according to each component’s position and characteristics and has good earthquake resistance and construction performance. This structure is now widely used in domestic and foreign multi-rise buildings.
Comparison of floor deck and ordinary reinforced concrete floor slab：
- floor deck can be used as permanent formwork for cast-in-place concrete, eliminating the process of installing and removing formwork during construction.
- The floor bearing plate can be used as a construction platform after installation, and at the same time, does not affect the work of the next floor construction plane because they do not have to use temporary supports.
- The floor bearing plate can be used as the bottom reinforcement of the floor slab, reducing the workload of installing the slab reinforcement.
- It can reduce the amount of floor concrete by 30%, reducing the self-weight of the floor slab can also reduce the size of beams, columns, and foundations and improve the structure’s overall performance.
Application Scope of Steel structure Warehouse mezzanine
It often used in the case of ample storage space, small goods, manual access, and ample storage capacity, which can make full use of space and save warehouse space.
A mezzanine structure for Steel Warehouse Building is an essential tool for modernization and improvement of warehouse efficiency. It can easily automate with the use of machinery. The steel warehouse building mezzanine is a storage device based on management and logistics such as packaging, transportation, loading and unloading, sorting. It is a necessary component of a modern industrial warehouse logistics center and distribution center.
