Composition and Classification

Composition: The platform structure typically consists 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, catering to various 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 pony walls of the factory column, typically serving as safety walkways or a simple medium-sized operation platform.

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

Platform supported by large equipment.

All are independent platforms.

For platforms supporting significant dynamic loads or heavy equipment, it is advisable to design them to be disconnected from the factory columns and to be directly supported by independent columns.

Platform structure arrangement

Comply with the requirements of production operation, ensuring clearances for passage and operation. The general minimum clear height for passage should not be less than 1.8M. Protective railings should generally be installed around the platform perimeter, with a height of about 1M. When the platform height exceeds 2M, a toe board of 100-150mm in height should also be set below the protective railings. A ladder for ascending and descending should be provided on the platform, with a width not less than 600mm.

When determining the flat dimensions, elevations, beam grids, and column layouts of the platform structure, in addition to meeting usage requirements, the arrangement of beams and columns should also consider the positions of equipment loads on the platform, as well as other significant concentrated loads, and the hanging of large-diameter industrial pipelines.

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

Safety Maintenance

1. Steel platforms should be equipped with load limit signs.

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

3. The concrete beams and slabs at the steel platform's support points should be fitted with embedment, 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. The beams and columns at the tension nodes on the upper part of the steel platform should be checked for tensile strength to ensure the safety of the building and the platform.

6. When using steel platforms, use clips; 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 other methods are used, there must be no fewer than 3 clips. A soft pad should be added at the sharp corner of the building where the wire rope is wrapped. The outer edge of the steel platform should be slightly higher than the inner side.

8. The steel platform must be equipped with fixed guardrails on both sides and a dense safety net must be hung.

Advantages and Disadvantages of Steel Platforms

Modern steel structure platforms come in a variety of structural forms and offer comprehensive functionalities. Characterized by their fully assembled structures, they are highly flexible in design, allowing for the creation of steel platforms that meet specific site requirements, functional needs, and logistics demands. They are widely used in modern storage facilities.

Today, land is becoming increasingly valuable and scarce. How to fit as much cargo as possible within limited space is a concern for many businesses. With the advancement of the times, the use of steel has become very widespread. Structures primarily made of steel are one of the main types of architectural structures currently in use. Steel structures, with their own characteristics, have gained dominance in the market.

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

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

Thirdly, its material has excellent plasticity and toughness, allowing for significant deformation, thus it can withstand dynamic loads well. Many large buildings in Suzhou are mainly constructed with steel structures, with steel structures as the main framework.

Fourthly, the construction period is short; a 300-square-meter building can be completed from construction to decoration in just a month with only five workers and thirty working days. It's a cost-saving, time-saving, and labor-saving solution!

Fifthly, steel structure buildings have a high degree of industrialization and mechanization, allowing for specialized production, which enhances work efficiency and reduces construction difficulties. They are well-aligned with the current high-speed, energy-saving society.

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

Steel structures are primarily used for the load-bearing skeletons in heavy industrial 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 super high-rise buildings.
