Composition and Classification

Composition: The platform structure usually 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:

A platform directly mounted on the factory column trusses or brackets, 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 significant dynamic loads or heavy equipment, it is advisable to design them to be decoupled from the factory columns and directly supported by independent columns.

Platform structure layout

Meet 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 skirting board of 100-150mm in height should also be set below the protective railings. A ladder for access up and down the platform should be provided, 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 location of equipment loads and other significant concentrated loads on the platform, as well as the suspension of large-diameter industrial pipelines.

The layout of the platform structure should strive for economic rationality and direct, clear force transmission. The arrangement of the beam grid should match its span. When the beam span is large, the spacing should also be increased. Make full use of the allowable span of the deck 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 support 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 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 embedded with hardware 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 installing steel platforms, use latches; do not allow the hook to hang directly from the platform's lifting ring.

7. During the installation of steel platforms, steel wire ropes should be securely fastened using hooks. When using other methods, there must be no fewer than 3 clips. At the sharp corner of the building where the steel wire rope is wrapped, a soft padding should be added. 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 suspended with dense-mesh safety nets.

Advantages and Disadvantages of Steel Platforms

Modern steel structure platforms come in a variety of structural forms and are fully equipped with functions. Their key feature is the fully assembled structure, which offers flexibility in design. They can be tailored to fit different site conditions, meet specific functional requirements, and comply with 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 in 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. With its own characteristics, steel structures dominate 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 exhibits good plasticity and toughness, allowing for significant deformation, thus it can withstand dynamic loads effectively. Many large buildings, which are predominantly constructed with steel structures, are located in Suzhou, featuring steel structures as the main component.

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

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 drawback is the poor fire resistance and corrosion resistance.

Steel structures are primarily used for the load-bearing skeletons of heavy 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.
