Floor bearing plate--200

Detailed introduction of the floor plate:

1. Structure composition

- Substrate: usually galvanized steel plate, thickness between 1.0mm and 1.5mm, with high strength and corrosion resistance.

- Compression design: The steel plate is pressed into a specific shape (such as trapezoid, wavy shape, etc.) through the cold pressing process to increase its stiffness and load capacity.

- Surface treatment: Some floor plates will be coated (such as epoxy resin coating) to improve corrosion resistance and aesthetics.

2. Main features

- Light weight and high strength: light weight but strong bearing capacity, can reduce the floor weight, reduce building load.

- Convenient construction: As a permanent formwork, concrete can be poured directly on it, saving the time of formwork installation and removal.

- Economical and practical: reduce the amount of concrete and construction costs, shorten the construction period.

- Fire resistance: When combined with concrete, it has good fire resistance.

- Seismic performance: the composite structure of steel and concrete has good seismic ability.

3. Application field

- Industrial and civil buildings: floors and roofing for office buildings, residential buildings, shopping malls, etc.

- Plant and warehouse: floor and roof structures for large-span plants.

- Public facilities: floors for stadiums, exhibition halls, airports and other long-span buildings.

Bridges and tunnels: temporary support structures for Bridges and lining of tunnels.

4. Common types

Classification by use

1）Floor bearing plate: mainly used for floor structure, which works together with concrete to form composite floor.

2）Roof bearing plate: mainly used for roof structure, usually combined with thermal insulation materials.

5. Installation and construction

Installation procedure

1）Pay-off positioning: Determine the laying position and direction of the floor bearing plate according to the design drawings.

2）Lay the floor bearing plate: Lay the floor bearing plate in sequence and fix it on the steel beam with tapping screws or welding.

3）Joint treatment: Ensure that the joints between the floor plates are tight, and use sealant if necessary.

4）Binding of steel bars: Binding of steel bars on the floor bearing plate to enhance the overall strength of the floor.

5）Concrete pouring: Concrete is poured on the floor bearing plate to form a composite floor.

Matters needing attention

- Ensure that the floor plate is laid perpendicular to the steel beam to improve the bearing capacity.

- The lap length of the floor bearing plate should meet the design requirements, usually not less than 50mm.

- The concrete should vibrate evenly when pouring to ensure that it is tightly combined with the floor plate.

6: Strengths

- Fast construction speed, shorten the construction period.

- Reduce the use of formwork and reduce construction costs.

- Light weight and high strength, reduce building load.

- When combined with concrete, it has good fire and earthquake resistance.

7. Market status and development trend

Because of its excellent performance and economic benefits, the floor bearing plate has been widely used in the construction industry. With the popularity of steel structure buildings and the promotion of green building concepts, the market demand for floor bearing plates continues to grow. In the future, the floor bearing plate will develop in the following directions:

- High performance materials: higher strength steels and more corrosion-resistant coatings.

- Multi-functional: The development of multi-functional floor bearing panels with thermal insulation, sound insulation and fire prevention.

- Intelligent construction: Combining BIM technology and automation equipment to improve construction efficiency and quality.

Sum up

Floor bearing plate is an efficient and economical building floor material, which has the advantages of light weight, high strength, convenient construction, economic and practical, and is widely used in industrial and civil buildings. With the advancement of technology, the performance and application range of floor bearing panels will be further improved to provide better solutions for the construction industry
