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, catering to static and dynamic load-bearing platforms, production auxiliary platforms, as well as medium and heavy-duty operational platforms, etc., based on usage requirements.

According to the different handling methods of the supports, 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, and on the other side by an independent column.

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 directly supported by independent columns.

Platform structure layout

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, and protective railings should generally be installed around the platform, with a height of about 1M. When the platform height exceeds 2M, a toeboard of 100-150mm in height should also be set below the protective railing. A ladder for ascending and descending should be provided on the platform, with a width not less than 600mm.

When determining the flat 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 and other significant concentrated loads on the platform, 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 anchoring points for the steel platform and the upper tie-backs must be located on the building structure and must not be set up on scaffolding or other construction equipment. The support system must not be connected to the scaffolding.

3. The concrete beams at the steel platform's support points should be fitted with embeds 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 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. 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, wire ropes should be securely fastened with hooks. When using other methods, there must be at least 3 clips. The sharp corner of the building where the wire rope is wrapped should be padded with soft material, and 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 secured with a dense safety net.

Advantages and Disadvantages of Steel Platforms

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

Today's society sees land becoming increasingly valuable and scarce. How to fit as much cargo as possible into limited space is a concern for many merchants. With the advancement of times, the use of steel has become extremely common, and structures primarily made of steel are one of the main types of architectural structures in use. With its own characteristics, steel structures dominate the market.

Firstly, steel is characterized by high strength, light weight, and great rigidity, making it particularly suitable for constructing large-span and ultra-high, ultra-heavy structures.

Secondly, steel structures have uniform material properties and good isotropy, making them ideal elastic bodies that comply with the basic assumptions of general engineering mechanics. They are a rare ideal building material.

Thirdly, its material possesses excellent plasticity and toughness, allowing for significant deformation, thus it can well withstand dynamic loads. Many large-scale buildings, with steel structures as the main framework, are located in Suzhou, which also utilizes steel structures as the main framework.

Fourth, with a short construction period, 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 level of industrialization and mechanization, enabling specialized production, improving work efficiency, and reducing construction difficulties. They are highly compatible with the current fast-paced, energy-efficient society.

Sixthly, the drawbacks include poor fire resistance and corrosion resistance.

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 like bridges and warehouses, as well as high-rise and super high-rise buildings.
