Composition and Classification

Composition: The platform structure is typically composed of deck boards, main and secondary beams, columns, inter-column supports, as well as ladders, railings, etc.

Category:

Indoor and outdoor platforms are available, as well as static and dynamic load-bearing platforms, production auxiliary platforms, and medium to heavy-duty operation platforms, all catering to specific usage requirements.

According to the different treatment methods of the bracket, the platform structure can also be divided into:

Platforms directly mounted on triangular brackets or cantilevers of the factory columns, typically serving as safety walkways or simple medium-sized operational platforms.

A platform supported on one side by a factory column or building wall, and on the other side by an independent column.

Platform supported on large equipment.

All are independent platforms.

For platforms supporting heavy dynamic loads or equipment of significant weight, it is advisable to decouple the design from the factory columns and directly support them on independent columns.

Platform structure layout

Meets the requirements for process production operations, ensuring clearances for passage and operation. The general clearance height for passage should not be less than 1.8M. Protective railings should be installed around the platform perimeter, typically 1M in height. When the platform height exceeds 2M, a toeboard of 100-150mm in height should be set beneath the railings. A ladder for access up and down the platform should be provided, with a width of no less than 600mm.

When determining the plan dimensions, elevation, beam grid, and column layout of the platform structure, in addition to meeting usage requirements, the arrangement of beams and columns should also consider the location of equipment loads on the platform and other significant concentrated loads, as well as the suspension of large-diameter industrial pipelines.

The arrangement of the platform structure should strive for economic rationality and direct, clear force transmission. The layout of the beam grid should be appropriate to its span. When the span of the beam is large, the spacing between them should also be increased. Make full use of the allowable span of the deck plates, and reasonably arrange the beam grid to achieve better economic results.

Safety Maintenance

1. Steel platforms should have load limit signs.

2. The support points of the steel platform and the upper tie points must be located on the building structure and must not be set on scaffolding or other construction facilities. The support system must not be connected to the scaffolding.

3. Concrete beams and slabs at the steel platform support points should be equipped with embedded components and connected to the platform with bolts.

4. The horizontal angle between the wire rope and the platform should be between 45 and 60 degrees.

5. Beams and columns at the upper tie nodes on the steel platform should be checked for tensile strength to ensure the safety of the building and the platform.

6. When installing steel platforms, use latches; do not allow the hook to hang directly from the platform's lifting ring.

7. During steel platform installation, the steel wire rope should be securely fastened with hooks. If using other methods, there must be at least 3 clips. The sharp corner of the building should be lined with soft padding where the wire rope is wrapped. The outer edge of the steel platform should be slightly higher than the inner side.

8. Both sides of the steel platform must be equipped with fixed guardrails and have dense mesh safety nets hung.

Advantages and Disadvantages of Steel Platforms

Modern steel structure platforms come in various structural forms and are fully equipped with functions. Their distinctive feature is the fully assembled structure, which offers flexibility in design. It can be tailored to meet site-specific requirements, usage functions, and logistics needs. They are widely used in modern storage facilities.

In today's society, land has become increasingly valuable and scarce. How to fit as much cargo as possible within limited space is a concern for many merchants. With the advancement of the times, the use of steel has become very widespread, and structures primarily made of steel are among the main types of building structures currently in use. Steel structures, with their unique characteristics, have gained dominance in the market.

One of its features is high strength, light self-weight, and great rigidity, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings.

Secondly, steel structures possess good homogeneity and isotropy of materials, are ideal elastic bodies, and conform to the basic assumptions of general engineering mechanics, making them a rare ideal building material.

Thirdly, its material has good plasticity and toughness, allowing for significant deformation, thus it can withstand dynamic loads effectively. Many large buildings, primarily constructed with steel structures, are located in Suzhou, which also feature steel structures as the main component.

Fourth, the construction period is short. A building of 300 square meters can be completed from construction to decoration in just one month with only five people and thirty working days. It's a cost-saving, time-saving, and labor-saving solution!

Fifthly, steel structural buildings have a high degree of industrialization and mechanization, enabling specialized production, enhancing work efficiency, and reducing construction difficulty. They are highly compatible with the current high-speed, energy-saving society.

The sixth drawback is the relatively poor fire resistance and corrosion resistance.

Steel structures are primarily used for the load-bearing skeletons in heavy-duty workshops, factory structures subjected to dynamic loads, plate and shell structures, tall television towers and masts, large-span structures such as bridges and warehouses, as well as high-rise and ultra-high-rise buildings.
