Heavy steel platforms are also well known. Modern heavy-duty steel platform has various structural forms and functions. The most important feature of this structure is that it is fully assembled and its design is flexible. It can design and manufacture steel that meets the site requirements and functional requirements, and meet the logistics requirements according to different site conditions. Heavy steel platforms are widely used in modern storage.
Composition and classification of heavy steel platforms:
1. Composition: Heavy steel platforms usually consist of slabs, usually supported by slabs, main girders and secondary girders, columns, pillars and railings.
Classification: According to the use requirements, it can be divided into indoor and indoor platforms, static and dynamic load platforms, production assistant platforms, medium and heavy operation platforms.
According to the different treatment methods of support, heavy steel platforms can also be divided into:
1) Heavy steel platforms are placed directly on tripods or brackets of factory columns, usually used as safe passages or simple medium-sized operating platforms.
2) The pillars of the building or the walls of the building support one side, and the other side has a platform with independent pillars.
3) Heavy steel platform supported by large equipment.

4) All are independent heavy steel platforms.

Layout of heavy steel platform:
1. To meet the requirements of production and operation of the process and ensure the clearance of transportation and operation. The general net height should not be less than 1.8M. Protective railings should normally be provided around heavy steel platforms. The height of the railings is usually 1M. When the height of heavy steel platform is greater than 2M, the kickboard with height of 100-150mm should be placed under the protective railing. Heavy steel platforms shall be equipped with ladders for upper and lower passages. The width of ladder should not be less than 600 mm.
2. In determining the plane size, height, beam and column layout of heavy-duty steel platform, besides meeting the use requirements, the layout of beam and column should also take into account the equipment load on the platform and other large centralized positions. Load and large diameter industry. Suspension pipeline, etc.
3. The layout of heavy steel platform should be economical and reasonable, and the driving force should be direct and clear. The layout of the beam should be adapted to its span. When the span of the beam is large, the spacing should also be increased. Making full use of the allowable span of deck and arranging beams reasonably can obtain better economic benefits.
