Strict quality inspection of modular steel platform shelves

Description :

　　Application of building steel structure attic:

　　Attic platform, also known as attic style shelf platform, second floor platform, warehouse platform, refers to building a platform in the warehouse and forming a shelf form to store and manage goods. Previously, the entire warehouse was required to store warehouse goods, but now only half of the storage space is needed, saving space utilization, investment, and factory costs.

　　Steel Structure Engineering Co., Ltd. provides you with Suzhou attic steel structure platform and steel structure staircase construction.

　　The design and construction of attic steel structure mainly targets: villa attic construction, villa steel structure with added steel stairs, steel reinforcement, two-story construction, building with additional floors, adding floors and roofs, duplex mezzanine attic, shop attic, loft, apartment type with added floors attic.

　　Generally, ordinary operating platforms are composed of main beams, small beams, and planks due to their low load-bearing capacity and lack of equipment support. Steel platform beams are mainly made of hot-rolled ordinary section steel. When the span is large, section steel or welded I-beam composite beams can also be used, and they can be supported on the factory building and other structures with triangular frames, support brackets, or directly supported.

　　Heavy duty operating steel platforms have large loads, frequent operations, large platform areas, and large, medium, and small vibration loads directly placed on the steel platform. Their structure usually consists of independent column grids, main beams, secondary beams, small beams, and planks. The steel platform structure has an independent support system, which is connected laterally to the structural framework columns of the factory building to ensure the integrity of the steel platform structure.

　　Steel structure platform structure columns and inter column supports

　　Steel platform columns are generally designed as equal section columns. The commonly used forms of solid web columns include hot-rolled ordinary steel sections, I-beams reinforced with plates, or steel pipes with flanges. If necessary, it can also be designed as a combined column form composed of two channel steels.

　　The strength, stability, and deflection of steel platform beams should be calculated. The fatigue strength calculation should also be carried out for beams that directly bear large vibration loads. The design of steel platform beams generally does not consider the development of plastic deformation; When necessary, calculate according to the requirements and formulas listed in the Steel Structure Design Code (GB50017-2003).

　　The simple connection method between the secondary beam and the main beam is stacking. Put the secondary beam directly onto the main beam and connect it with welds or bolts. The required building clearance for stacking is large, and the use of this method is often limited. Therefore, the equal height connection between the secondary beam and the main beam is a commonly used method. There are two construction forms for the hinge connection between beams and columns:

　　Setting the beam directly on the top of the column makes the connection structure relatively simple. The total reaction force of the beam support is transmitted to the column stiffeners through the connection weld between the top plate and the column stiffeners or through the end face of the beam stiffeners under pressure. The force is then transmitted to the column web through the vertical connection weld between the column stiffeners and the column web.

　　Design of Steel Platform Structure Deck

　　Steel platform planks can be divided into fixed and detachable according to the production process requirements; According to the structure, it can generally be divided into plate type, grate type, and joint structure composed of steel beams and concrete slabs.
