Mini Fix Spacer

Plastic Spacers

Mini Fix Spacer

عددی

The Mini Fix plastic spacer is specifically designed for concrete sections with low thickness or for structures requiring reduced load-bearing capacity. This type of spacer is suitable for projects utilizing rebars with diameters less than 12 mm. Common applications of the Mini Fix spacer include:

Casting of joist-and-block slab systems
Steel deck slab concreting
Various types of floors and slabs constructed with lightweight rebar meshes
Production of precast concrete components

🧱 Features and Applications of Mini Fix Spacer

🔩 Load Capacity

The Mini Fix Spacer can withstand a point load of 25 to 35 kg, depending on its height. Load-bearing capacity may vary with spacer size.

📏 Compatible Rebar Sizes

Designed to accommodate rebars with diameters from 6 to 16 mm within its locking prongs. It is primarily used in steel structures with maximum rebar diameter of 12 mm.

💰 Design and Cost Efficiency

Engineered with reduced weight and volume, the Mini Fix Spacer is highly economical for lightweight structural applications.

📐 Consumption Guidelines

For structures with lightweight rebar mesh, typically 4 spacers per square meter are sufficient to ensure proper concrete cover.
For denser and heavier reinforcement grids, the number of spacers should be calculated based on the weight of the rebar mesh per square meter and the point load capacity of the Mini Fix Spacer.

🛠️ Applications and Benefits

Material & Strength: Made of durable plastic, suitable for supporting rebar meshes in lightweight structural slabs.
High Usage Rate: One of the most widely used floor and slab spacers in the construction industry.
Standard Compliance: Ensures precise vertical spacing under rebar mesh and formwork, providing concrete cover in accordance with Technical Specifications and National Building Code – Part 9.

⚠️ Key Considerations for Mini Fix Plastic Spacer

🔧 Design & Usage

Optimized for horizontal surfaces with lightweight rebar grids, such as slabs and low-load concrete floors.

🚫 Rebar Size Limitations

Recommended for rebars up to 12 mm in diameter. For larger diameters or heavier structures, stronger spacers like Max Fix or Hard Fix are advised.

🧱 Load Capacity

Although capable of holding rebars up to 18 mm, its maximum point load capacity of 35 kg makes it unsuitable for heavy structures. Use stronger alternatives for such cases.

🧩 Installation Notes

Avoid twisting or rotating the rebar during placement, as this may damage the spacer prongs and compromise rebar stability.

📊 Spacer Quantity Calculation

If the calculated rebar mesh weight and live/dead loads exceed the spacer’s load capacity, increasing the number of Mini Fix spacers is not efficient. Instead, use Max Fix spacers, which offer four times the point load capacity, reducing quantity and improving cost-effectiveness and installation speed.

📦 Storage and Handling

Store away from frost, excessive heat, and prolonged direct sunlight.
Ideal temperature range: +10°C to +30°C

📈 Consumption Rates

Application Type	Quantity Needed	Notes
Lightweight Slabs	4 pcs/m²	Suitable for light rebar mesh and low loads
Beams and Light Girders	4 pcs/meter (linear)	Install with 5 cm spacing per row

🧱 Mini Fix Spacer – Material and Performance Characteristics

The Mini Fix Spacer is a small, lightweight component made of durable plastic, typically manufactured from polypropylene (PP) or high-density polyethylene (HDPE). Due to its compact dimensions, it is designed for rebars with smaller diameters (commonly 6 to 12 mm) and provides limited concrete cover height, usually ranging from 15 to 30 mm.

⚙️ Physical Properties

Engineered with precise and stable geometry, the Mini Fix Spacer remains firmly in place beneath the rebar during installation.
It supports the weight of rebar and concrete in light-duty applications.
Performs reliably in both dry and humid environments.
Offers sufficient resistance to light mechanical pressure, but is not suitable for heavy structural loads.

🧪 Chemical Properties

The polymer structure is resistant to moisture, alkaline substances, and chemical agents present in concrete.
To enhance durability, additives such as UV stabilizers and antioxidants may be incorporated.
The spacers are non-corrosive, non-toxic, and chemically stable, though like other plastics, they are non-biodegradable in nature.

🌡️ Thermal Resistance

Withstands temperatures up to approximately 120–140°C.
Under normal concreting and curing conditions, the spacer does not undergo chemical or physical changes.

🛠️ How to Use the Mini Fix Plastic Spacer

To ensure proper installation of the Mini Fix Spacer, follow these steps:

1. Placing the Rebar into the Spacer

The Mini Fix Spacer is equipped with two serrated prongs designed to lock and secure the rebar. Carefully insert the rebar between the spacer’s prongs.

2. Locking the Rebar

Once the rebar is positioned, gently press it down until the prongs firmly grip the rebar. This locking mechanism ensures the rebar remains fixed in its correct position.

3. Seating the Rebar on the Base

The rebar must rest fully on the spacer’s seating surface. This placement determines the distance between the bottom of the rebar and the formwork or concrete surface, which defines the concrete cover.

4. Ensuring Proper Concrete Cover

Make sure the distance from the spacer base to the bottom of the formwork is sufficient to provide the required concrete cover, in accordance with technical specifications.

By following these steps, the Mini Fix Spacer will be correctly installed, ensuring the rebar is securely positioned and the concrete cover meets design and regulatory standards.
