Max Fix Spacer

عددی

The Max Fix Spacer is a type of plastic rebar chair specifically designed for horizontal structural elements subjected to moderate loads and standard reinforcement weight. It is particularly suitable for projects involving:

Beams
Tie beams (Poutres)
Grade beams (Shenazh)
Stair landings and intermediate slab levels
Medium-weight floors and lightweight ceilings

Its engineered design ensures proper concrete cover and rebar stability during pouring, making it a reliable choice for semi-heavy structural applications.

🧱 Max Fix Spacer – Features and Applications

Usage Range The Max Fix Spacer is designed for rebar grids with diameters ranging from 8 to 22 mm. It is an ideal choice for structural elements with medium weight, where standard rebar sizes are used. Load Capacity This spacer can withstand point loads between 150 and 180 kg. Based on the total rebar weight and live/dead loads, the appropriate number of Max Fix spacers should be calculated to ensure proper concrete coverage. Quality and Standards Known as a semi-heavy-duty plastic spacer, Max Fix contributes to improved construction quality and complies with international standards for reinforced concrete works. Sizes and Design Available in four different sizes, Max Fix is a relatively rigid plastic component designed to hold rebar securely in place during concrete pouring.

⚠️ Usage Guidelines for Max Fix Spacer

Proper Application: Suitable for horizontal surfaces with medium-weight rebar grids, such as slabs, stair landings, beams, and semi-heavy ceilings.
Rebar Diameter: Designed for rebar up to 22 mm. For diameters up to 32 mm, use Hard Fix Spacer. For larger diameters, plastic spacers alone may not be sufficient.
Selection and Calculation: Always calculate the required number of spacers based on the load-bearing capacity, rebar grid weight per square meter, and expected loads. For heavier grids, switching to Hard Fix spacers is more logical and cost-effective.
Minimum Rebar Diameter: Recommended for rebar ≥12 mm. Smaller diameters may not lock securely in the spacer clips.
Installation Tip: Avoid twisting or lateral rotation of the rebar during placement, as this may damage the spacer clips and compromise concrete cover quality.

📏 Consumption Rates

Application Type	Recommended Quantity
Medium-weight slabs	4 pcs/m²
Heavier slabs (rebar ≤ 22 mm)	6–8 pcs/m²
Beams and footings	2 pcs/meter (spaced 60–70 cm)

Following these guidelines ensures optimal performance and durability of the reinforcement system.

🧱 Max Fix Plastic Spacer – Material, Durability, and Thermal Properties

General Description The Max Fix Spacer is a lightweight, rigid, and durable plastic component used to maintain precise spacing between rebar and concrete formwork in reinforced concrete structures. These spacers are manufactured from high-density plastics, typically polypropylene (PP) or similar polymer blends, using injection molding technology. Their engineered design ensures dimensional stability under the pressure of rebar and fresh concrete, preventing deformation during placement.

Chemical Resistance The raw materials used in Max Fix spacers offer excellent resistance to:

Moisture
Acids and alkalis commonly found in concrete
Chemical degradation and corrosion

To enhance outdoor durability, UV stabilizers are added to the plastic compound. Under normal usage conditions, these spacers are non-toxic and safe, although—like most plastics—they are non-biodegradable.

Thermal Stability Max Fix spacers remain stable under typical ambient temperatures. Softening or thermal degradation may begin only at elevated temperatures above 120–150°C.

Product Variants and Coverage Thanks to their engineered geometry, Max Fix spacers are available in various forms—slab-type, wall-type, and linear-type—to suit different structural applications. They provide concrete cover in multiple sizes, typically ranging from 2 to 7 cm, depending on design requirements.

🛠️ How to Use the Max Fix Plastic Spacer

To ensure proper installation and performance of the Max Fix Spacer, follow these steps:

1. Rebar Placement Place the rebar directly onto the seating platform of the Max Fix Spacer. This platform is designed to support the rebar at the correct elevation.

2. Rebar Locking Secure the rebar using the locking clips integrated into the spacer. These clips are specifically engineered to hold the rebar firmly in place, preventing movement during concrete pouring.

3. Concrete Cover Formation Once the rebar is seated and locked, the vertical distance between the bottom of the rebar and the formwork surface defines the concrete cover. This cover—known as concrete protection layer—is established precisely according to project specifications.
