The double spacer consists of two parts, male and female. This spacer is produced in different sizes. The number of use of these double spacers in the concrete slab is 4 per square meter.Suggested: Construction steps of concrete building using spacersDouble spacer is a type of spacer that consists of two pieces. A fragment is empty and is used as a base. The other piece has grooves that hold the bars in place.Double spacers are usually used to cover rebar in medium-weight concrete structures such as beams, putters, shingles and medium-weight floors.One of the other types of tiling tools and parts is the ceramic tile leveler, which is also known in the market with names such as tile clips and tile wedges, tile clips or ceramic tile levelers, and like other types of ceramic tile spacers as a The useful piece is important in the beauty and ease of tiling. 
* High resistance: Double spacers have higher resistance than plastic spacers and are suitable for heavier applications.* High stability: Double spacers are more stable than plastic spacers and do not change shape due to vibration or impact.Overall, double spacers are a useful tool for providing rebar cover in medium-weight concrete structures. These spacers are durable, stable and easy to install.In Iran, double spacers are usually made of plastic or metal. These spacers are available in different sizes and diameters. Double spacers are usually installed manually.
* **Use proper sized spacers. The size of the spacers should match the diameter of the bars and the amount of coverage required.* **Put the spacers accurately between the bars. This will allow the concrete to flow evenly around the rebars.* **Put the spacers firmly in place. This prevents them from moving in the concrete.By following these tips, you can use double spacers effectively and improve the quality of your concrete.

The application of a double spacer refers specifically to construction and maintaining the proper distance between two layers of rebar in concrete elements. Here’s a breakdown of its uses:
Maintaining Concrete Cover: Double spacers ensure a consistent concrete cover around the rebar. This cover is crucial for protecting the rebar from corrosion caused by moisture and other environmental factors.
Double Mesh Slabs: They are particularly useful in concrete slabs that utilize double mesh reinforcement. The double design allows for separate placement on the top and bottom mesh layers.
Versatility: Double spacers can be used in various concrete structures like slabs, walls, foundations, and even large projects like dams and tunnels.
Here are some additional points to consider:
Material and Design: Double spacers are typically made of plastic and come in interlocking parts for easy installation.
Quantity: The number of double spacers used can vary depending on the project specifications and weight of the rebar structure. Usually, around 4 spacers per square meter is a good starting point.
Alternatives: For heavier rebar loads or situations where the upper mesh has a larger diameter, alternative spacer configurations like double fix base spacers used with hard fix spacers might be recommended.
If you’d like to learn more about specific types of double spacers or their installation process, searching for “double fix spacer” or “double concrete spacer” online can provide more detailed information.
More weight: Double spacers weigh more than plastic spacers, which can make them more difficult to transport and work with.More cost: Double spacers are more expensive than plastic spacers.Need for precise installation: Double spacers must be accurately placed between the rebars so that the concrete flows evenly around the rebars. Otherwise, concrete cracking may occur.Overall, double spacers are a useful tool for rebar cladding in medium-weight concrete structures, but they also have disadvantages that should be considered.Here are some tips to mitigate the disadvantages of double spacers:Use lightweight double spacers.Use double spacers at a reasonable price.Use a precision tool to install double spacers.By following these tips, you can avoid the disadvantages of spacer double to a great extent. 
In conclusion, the double spacer plays a vital role in ensuring the quality and longevity of concrete structures. Here’s a summary of its key points:
Function: Maintains a consistent concrete cover around rebar for corrosion protection.
Application: Useful in concrete slabs (especially double mesh slabs), walls, foundations, and various other structures.
Benefits: Ensures proper concrete placement, protects rebar from corrosion, and offers versatility in application.
Material and Design: Typically made of interlocking plastic parts for easy installation.
Overall, double spacers are a simple yet crucial element in concrete construction, promoting structural integrity and durability.
