SOG Bar Chairs: Key Features and Specifications You Need to Know

SOG Bar Chairs, or Slab On Ground Bar Chairs, are used in construction to support reinforcement bars in concrete slabs. They ensure the bars maintain the correct positioning during concrete pouring, enhancing the slab’s structural integrity. These chairs are crucial in preventing the reinforcement bars from shifting, which helps in maintaining the design specifications and strength of the concrete structure.

SOG Bar Chair are crucial because they keep reinforcement bars in place, preventing them from shifting during concrete pouring. This ensures the concrete structure’s strength and stability, reducing the risk of structural failure. Properly positioned reinforcement bars improve load distribution, minimize cracking, and enhance the overall durability of the concrete slab.

Yes, Combination SOG Bar Chair are versatile and can be used in various construction projects. These include residential and commercial buildings, infrastructure projects like light rail and tunnels, and industrial facilities. Their adaptability to different slab thicknesses and reinforcement requirements makes them suitable for a wide range of applications, ensuring consistent performance across diverse project types.

Plastic SOG Bar Chair are resistant to corrosion and weathering, ensuring long-term durability. They are also lightweight and easy to handle, which simplifies installation. Additionally, plastic bar chairs are cost-effective and environmentally friendly, as they can be made from recycled materials. Their non-conductive properties also prevent any potential interference with electrical currents in the concrete.

Ensure the surface is clean and free from debris before placing the bar chairs. This provides a stable base and ensures proper support for the reinforcement bars. Cleaning the surface removes any obstacles that might prevent the bar chairs from sitting evenly, which is essential for maintaining the correct position of the reinforcement bars throughout the concrete pouring process.

Yes, Combination SOG Bar Chairs are adaptable and can be used for both light and heavy-duty projects. This includes residential slabs and industrial concrete floors. Their robust construction ensures they can handle significant loads without deforming, making them suitable for high-stress environments as well as standard construction applications.

After positioning the bar chairs under the reinforcement bars, make sure they are stable and won’t move during concrete pouring. Proper placement is crucial for maintaining the integrity of the reinforcement setup. You can check the stability by gently pressing on the reinforcement bars; the chairs should hold firm without tipping or shifting. Secure placement ensures that the bars remain in the designed position, which is vital for the structural integrity of the concrete slab.

The number of bar chairs needed per sheet of mesh can vary depending on the size and spacing of the mesh, as well as the specific requirements of the project. Generally, bar chairs are placed at regular intervals, such as 4 to 6 chairs per square meter, to ensure adequate support and stability of the reinforcement bars.

For a 100mm slab, the appropriate size of bar chairs would typically be around 50/65mm. This size ensures that the reinforcement bars are positioned correctly within the slab, providing the necessary coverage and structural support required for the thickness of the slab.

The number of bar chairs needed per meter depends on the spacing required for the reinforcement bars and the specific design of the concrete slab. A common practice is to place bar chairs at intervals of 300mm to 500mm along the length of the reinforcement bars, which usually translates to about 2 to 4 bar chairs per meter.
