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, static and dynamic load-bearing platforms, production auxiliary platforms, as well as medium and heavy-duty operation platforms, can be categorized according to usage requirements.

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

A platform directly mounted on the factory column brackets or bullnoses, typically serving as a safety walkway or a simple medium-duty operation platform.

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 substantial 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

Meets the requirements for process production operations, 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, with a height of about 1M. When the platform height exceeds 2M, toeboards 100-150mm in height should also be set below the protective railings. Ladders for ascending and descending should be provided on the platform, with a width not less than 600mm.

When determining the plane dimensions, elevation, beam grid, and column arrangement of the platform structure, in addition to meeting usage requirements, the placement of beams and columns should also consider the positions of equipment loads on the platform, as well as large concentrated loads, and 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 be equipped with 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. The concrete beams and slabs at the steel platform 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 ideally be between 45° and 60°.

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

6. Use a ring clip for steel platforms; do not allow the hook to directly hang from the platform's lifting ring.

7. During the installation of steel platforms, wire ropes should be securely fastened with hooks. If using other methods, there must be at least 3 clips. At the sharp corner of the building where the wire rope is wrapped, a soft pad should be added. 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 have a dense mesh safety net hung overhead.

Advantages and Disadvantages of Steel Platforms

Modern steel structure platforms come in a variety of structural forms and are fully equipped with functions. Their characteristic is a fully assembled structure, with flexible design that allows for customization based on different site conditions. Steel platforms that meet the specific requirements of the site, usage functions, and logistics are designed and manufactured. They are widely used in modern storage solutions.

Today, land is becoming increasingly valuable and scarce. How to fit as much cargo as possible in 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 among the main types of architectural structures currently in use. Steel structures, with their own characteristics, are dominating the market.

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

Secondly, the materials for steel structures are homogeneous and isotropic, making them ideal elastic bodies that conform to the fundamental assumptions of general engineering mechanics. They are a rare ideal building material.

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

Fourthly, the construction period is short. A 300-square-meter building can be completed from construction to decoration in just one month, requiring only five people and thirty working days. It's truly cost-effective, time-saving, and labor-saving!

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

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

Steel structures are primarily used for the load-bearing frames 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 super high-rise buildings.
