Steel structure platform is also called working platform. Modern steel platform has many forms and functions. Its largest structure is fully assembled structure, flexible design, widely used in modern storage.
Layout of steel platform structure:
To meet the requirements of process operation and ensure the clearance of traffic and operation. The average net height is not less than 1.8M. Protective railings should normally be provided around the platform. The height of the railings is usually 1M. When the height of the platform is greater than 2M, the kickboard with the height of 100-150mm should be placed under the protective railing. The platform shall be equipped with ladders for upper and lower passages. The width of ladder should not be less than 600 mm.
In order to determine the plane size and height of the platform structure, besides meeting the installation requirements of beams and columns, the arrangement of beams and columns should also take into account the equipment loads on the platform and other large concentrated location loads and large diameter industrial pipelines. The structural layout of platform such as suspension should be economical and reasonable, and the transmission force should be direct and clear. The layout of the beam should be adapted to its span. When the span of the beam is large, the spacing should also be increased. Make full use of deck span and arrange beams reasonably in order to obtain better economic results.
Safety Maintenance of Steel Platform:
1. Limit cards should be installed on steel platform.
2. The shelf point and the upper breakpoint of the steel platform must be located on the building, not on the scaffolding and other construction facilities, and the support system should not be connected to the scaffolding.
3. Concrete beams and slabs at rest points of steel platform should be embedded and bolted to the platform.
4. The horizontal angle between the wire rope and the platform should be 45 to 60 degrees.
5. The tensile strength of beams and columns at the upper pull point of steel platform should be checked to ensure the safety of buildings and platforms.
6. The clasp should be used in the steel platform, so that the hook should not be directly hooked to the platform ring.
7. When installing the steel structure platform, the steel rope shall be fixed by special hooks. When using other methods, the fastening ring should be no less than 3, and the cable angle of the building should be lined with cushion. The outer surface of steel platform should be slightly higher.
8. The steel platform must be fixed on the left and right sides of the platform and suspended with a dense mesh safety net.
Advantages and disadvantages of steel platform:
Modern steel platform has many forms and functions. The most important feature of this structure is its complete structure and flexible design. It can design and manufacture steel structure platform to meet the requirements of the site according to different site conditions. Use function requirements and meet logistics requirements. It is widely used in modern storage. Today is social land is becoming more and more precious and scarce. How to place as many goods as possible in a limited space is a problem that many enterprises consider. With the development of the times, the use of steel has become very common. The structure based on steel production is one of the most important building structure types.
First, the characteristics of steel platform are its own high strength. Light weight, especially suitable for the construction of large-span and ultra-heavy buildings;
Secondly, the material structure of steel platform has good uniformity and isotropy. It is an ideal elastic body and meets the basic assumptions of general engineering mechanics. It is the ideal building material nowadays.
Third, its material plasticity_has good toughness and can be greatly deformed, so it can well withstand dynamic loads. Many large buildings are mainly steel platforms. Today, the world is first door is located in Suzhou, where steel platforms are the main platform.
Fourth, the construction period is short. It only takes 5 people and 30 working days to build a 300 square metre building. From building to renovation, it takes only one month to complete. It can save money, time and manpower!
Fifth, the steel platform building has a high degree of industrialization and mechanization, which can carry out specialized production, improve work efficiency and reduce the difficulty of construction. This stage is in line with the high-speed and energy-saving society.
Sixth, the disadvantage is poor fire resistance and corrosion resistance.
Steel structure platform is mainly used in heavy workshop load-bearing frame, power plant structure, plate and shell structure, high-rise television tower and mast structure, large-span structure such as bridge and reservoir high-rise and super high-rise buildings.
