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 support, the platform structure can also be divided into:

A platform directly mounted on the triangular brackets or haunches of the factory columns, 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, with an independent column on the other side.

Platform supported on 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 layout

Meet the requirements of 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, typically 1M in height. When the platform height exceeds 2M, a toe board of 100-150mm in height should be placed under 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 plan dimensions, elevation, beam grid, and column arrangement of the platform structure, in addition to meeting usage requirements, the arrangement of beams and columns should also consider the position of equipment loads on the platform, other significant concentrated loads, and the hanging of large-diameter industrial pipelines.

The layout of the platform structure should strive for economic reasonableness and direct, clear transmission of forces. The arrangement of the trusses should match their spans. When the span of the beams is large, the spacing between them should also be increased. Make full use of the permissible span of the deck plates, and rationally arrange the trusses 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 must not be set on scaffolding or other construction equipment. 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 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 degrees.

5. The beams and columns at the tie 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 S-hooks; do not allow the hook to directly hang from the platform's lifting loop.

7. When installing steel platforms, wire ropes should be securely fastened with hooks. If other methods are used, there must be no fewer than 3 clips. Soft padding 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. Steel platforms must be equipped with fixed guardrails on both sides and secured with a dense mesh safety net.

Advantages and Disadvantages of Steel Platforms

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

Today's society sees land becoming increasingly valuable and scarce. How to place as much cargo as possible in limited space is a concern for many merchants. With the advancement of the times, the use of steel has become very common, and structures mainly made of steel are one of the main types of current construction. Steel structures, with their own characteristics, dominate the world.

Firstly, steel boasts high strength, low self-weight, and great stiffness, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings.

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

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

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

Fifth, 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 drawbacks include poor fire resistance and corrosion resistance.

Steel structures are primarily used for load-bearing frames in heavy-duty workshops, factory structures subject 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.
