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 support, the platform structure can also be divided into:

Platforms directly mounted on the factory column brackets or corbels, 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 with significant dynamic loads or heavy equipment, it is advisable to decouple the design from the factory columns and directly support them on independent columns.

Platform structure arrangement

Comply with the requirements for process production operations, ensuring clearances for passage and operation. The general clearance for passage should not be less than 1.8M, and 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 placed below the protective railings. A ladder for ascending and descending should be provided on the platform, with a width that should not be 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 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 deck plates, and reasonably arrange the beam grid to achieve a better economic effect.

Safety Maintenance

1. Steel platforms should have load limit signs.

2. The support points of the steel platform and the tie points at the top must be located on the building itself and must not be set up on scaffolding or other construction equipment. The support system must not be connected to the scaffolding.

3. Concrete beams at the steel platform's support points should be fitted with embedments and connected to the platform with bolts.

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

5. The beams and columns at the tension joints 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 installing steel platforms, use clamps; do not allow the hook to directly hang from the platform's lifting ring.

7. During steel platform installation, the steel wire rope should be securely fastened with hooks. When using other methods, there must be no fewer than 3 clips. Soft padding should be added to the sharp corner areas of the building where the wire rope is wrapped, and 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 a dense mesh safety net suspended.

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 customization to meet specific site conditions, usage requirements, and logistics needs. 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 merchants. 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 building structures currently in use. Steel structures, with their own characteristics, have gained dominance in the market.

One of its features is that steel has high strength, low self-weight, and great rigidity, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy structures.

Secondly, steel structures have good homogeneity and isotropy of materials, belong to 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 enabling it to withstand dynamic loads effectively. Many large-scale buildings in Suzhou are predominantly constructed with steel structures as the main framework.

Fourthly, 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!

The fifth point is that steel structure buildings have a high degree of industrialization and mechanization, allowing for specialized production, enhancing work efficiency, and reducing construction difficulties. They are highly compatible with the current high-speed, energy-saving society.

Sixthly, the drawback is its 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 like bridges and warehouses, as well as high-rise and ultra-high-rise buildings.
