Plastic Spacers

عددی

Plastic spacers with specialized designs are used for heavy-duty applications and foundations. This product, known as “Hard Fix,” is suitable for withstanding high pressure in large and heavy concrete structures such as foundations and concrete sections with thick rebars.

Sharing:

In large-scale structures and foundations, which typically involve thick rebar and dense reinforcement meshes, spacers capable of withstanding heavy loads are required. Due to its high strength and durability, Hard Fix is an ideal choice for providing proper concrete cover in heavy-duty projects such as beams, tie beams, and foundations. This type of spacer can withstand point loads ranging from 350 to 600 kilograms. Considering the weight of the rebar and both live and dead loads, placing an adequate number of Hard Fix spacers ensures optimal concrete coverage for the reinforcement. Plastic spacers are made from durable plastic materials, and Hard Fix is one of the most prominent examples. It serves as a spacer between rebar and formwork in columns, concrete walls, and structural ceilings, and effectively maintains the distance between rebar and the foundation.

Important Notes on Hard Fix When using Hard Fix, consider the following:

Rebar Diameter: Hard Fix is designed for rebar up to 32 mm in diameter. For larger diameters, standard plastic spacers are not recommended, and alternative options may be necessary.
Use in Heavy Surfaces: Due to its special design and high load-bearing capacity, this product is suitable for heavy and semi-heavy surfaces. It may not be ideal for structures requiring concrete cover for smaller-diameter rebar.
Recommended Rebar Diameter: For best results, use Hard Fix with rebar of at least 14 mm in diameter. Smaller rebar may not lock securely into the spacer’s prongs, potentially affecting concrete cover dimensions.
Load and Quantity Calculation: In areas with ultra-heavy reinforcement meshes, calculate the rebar structure’s weight per square meter. Based on the point load capacity of Hard Fix and existing live and dead loads, determine the required number of spacers.
Economic Choice: If the rebar mesh weight and loads per square meter are moderate or low, Max Fix spacers may be used instead of Hard Fix to reduce costs.
Installation Precautions: Avoid twisting or side-turning the rebar during installation, as this may break the spacer’s plastic prongs.

By following these guidelines, you can use Hard Fix efficiently and achieve maximum performance.

Usage Rate of Hard Fix Optimal usage depends on the type and conditions of the structure. Recommended quantities for different applications are:

Foundations and semi-heavy floors: 4 Hard Fix spacers per square meter
Heavy and massive floors: 6 to 10 Hard Fix spacers per square meter, depending on structure volume and load
Beams and girders: 2 Hard Fix spacers every 60 to 70 cm along the length, in a row

Following these quantities ensures effective use of Hard Fix for achieving proper concrete cover.

Storage and Handling of Hard Fix

Conditions: Keep away from cold, frost, heat, and prolonged direct sunlight
Optimal Temperature: Between +10°C and +30°C

Hard Fix plastic spacer is a lightweight and durable component made from polypropylene or polyethylene, designed to maintain precise spacing between rebar and concrete formwork. It is resistant to pressure, impact, moisture, and the chemical components of concrete, and is manufactured in various sizes to ensure proper concrete coverage. Chemically stable and non-corrosive, it is safe under normal temperatures but may degrade at high temperatures (above 200°C). These spacers are non-toxic but not biodegradable.

How to Use Hard Fix

To use Hard Fix, follow these steps:

Placing the Rebar: First, position the rebar on the seating area of the Hard Fix spacer.
Locking the Rebar: The rebar is secured in place using the locking prongs integrated into the spacer’s design.
Creating Concrete Cover: Once the rebar is placed on the Hard Fix and concrete is poured, the space between the underside of the rebar and the surface of the concrete form is filled, thereby establishing the required concrete cover.

Thanks to its specialized design, the Hard Fix spacer can easily hold the rebar in the correct position and ensure proper concrete coverage.
