Solar Wheel Fix Spacer

Plastic Spacers

عددی

The plastic Wheel Fix Spacer, also known as the solar spacer or wheel-type spacer, is used to ensure precise and uniform concrete coverage on vertical surfaces. These spacers are designed for walls, columns, and circular vertical sections in both cast-in-place and precast concrete applications, and are manufactured in accordance with BSI 7973 standards.

Advantages and Features of Solar Wheel Fix Spacer Corrosion Prevention of Rebar:

In concrete walls and columns, using the Wheel Fix Spacer ensures uniform concrete coverage around the rebar, preventing it from approaching the concrete surface and rusting. Structure and Design: The Wheel Fix Spacer features a strong central locking mechanism to hold the rebar securely. Side fins prevent the impact of vibration and intense concrete pouring on the concrete surface. These fins also block the penetration of chloride ions, sulfates, acids, and other harmful agents into the concrete. Use in Vertical Surfaces: Using the Wheel Fix Spacer on vertical surfaces such as walls and columns ensures that the rebar mesh remains perfectly parallel to the formwork, preventing misalignment and congestion inside the mold. Load Capacity and Dimensions: The load-bearing capacity of the Wheel Fix Spacer varies depending on the diameter and size of the rebar. It is specially designed to accommodate rebar of appropriate diameters. Resistance to Vibration: The fins of the Wheel Fix Spacer provide resistance against strong vibrations during concrete pouring, minimizing their impact on the concrete surface. By using the plastic Wheel Fix Spacer, you can ensure uniform and proper concrete coverage over the rebars, protecting them from environmental damage. These spacers are widely used in various construction projects to reinforce concrete structures and enhance their durability. — Important Notes on Using Plastic Wheel Fix Spacer Application on Vertical Surfaces: The Wheel Fix Spacer is specifically designed for use on vertical surfaces such as walls and columns. It is not suitable for horizontal surfaces. Spacing When Stirrups or Tie Rods Are Outside the Rebar Mesh: If stirrups or tie rods are placed outside the rebar mesh, Wheel Fix Spacers should be spaced 75 cm apart. Installation When Stirrups or Tie Rods Are Inside the Rebar Mesh: If stirrups or tie rods are inside the rebar mesh, the plastic Wheel Fix Spacers should be installed on the main vertical rebars. Additional Notes: Secure Installation: Ensure that the spacers are firmly and securely attached to the rebars and remain fixed during concrete pouring. Compatibility with Rebar Size: Make sure the spacer size matches the rebar diameter to hold the rebar properly and ensure uniform concrete coverage. Resistance to Vibrations: The fins of the Wheel Fix Spacer are designed to withstand strong vibrations during concrete pouring and minimize their effects. Protection Against Environmental Factors: Using the Wheel Fix Spacer prevents the penetration of chloride ions, sulfates, acids, and other harmful agents into the concrete, protecting the rebars from corrosion and the concrete from damage. Following these guidelines will help you use the Wheel Fix Spacer effectively and avoid potential issues. — Usage Rate of Plastic Wheel Fix Spacer Walls and Vertical Surfaces with Normal Pressure from Concrete Formwork: Usage Rate: 3 Wheel Fix Spacers per square meter for each side of the reinforced surface. Vertical Surfaces with Heavy or Special Formwork (e.g., Tunnel Formwork): Usage Rate: 4 to 6 Wheel Fix Spacers per square meter for each side of the wall. Columns: Columns up to 50×50 cm: Usage Rate: Minimum 16 Wheel Fix Spacers per 3-meter column. (2 spacers per stirrup side, repeated every 1.5 meters in height.) Columns Larger than 50 cm: Usage Rate: Up to 48 plastic Wheel Fix Spacers may be required for a 3-meter column. By following these patterns, you can ensure optimal and efficient use of plastic Wheel Fix Spacers in various construction projects. — Storage and Maintenance of Plastic Wheel Fix Spacer Conditions: Keep away from frost, extreme heat, and prolonged direct sunlight. Ideal Temperature: +10 to +30°C

The solar Wheel Fix Spacer is made of durable plastic and features a circular design with radial fins that stabilize it around the rebar and ensure uniform spacing from the formwork. This type of spacer is designed for rebars of various diameters and is commonly available in sizes that provide concrete cover ranging from 2 to 7 centimeters.

Physically, the spacer is lightweight yet highly resistant to lateral pressure from fresh concrete. Its wheel-like shape helps distribute the load evenly across the formwork surface and prevents rebar displacement. Installation is very simple—it locks around the rebar with a press-fit mechanism. It is ideal for use in vertical structures with high rebar density.

Chemically, the main material of this spacer is typically polypropylene (PP) or high-density polyethylene (HDPE), which offers excellent resistance to moisture, alkaline substances, and chemical compounds found in concrete. To enhance durability against sunlight and harsh environmental conditions, it often contains UV stabilizers and anti-oxidation additives. These spacers remain stable at ambient temperatures but may deform at high temperatures (around 130 to 150°C).

Additionally, these spacers are non-toxic, non-corrosive, and safe for use in construction environments. However, like other polymer-based spacers, they are not biodegradable and should not be discarded in nature.

Application Method of Plastic Wheel Fix Spacer

The plastic Wheel Fix Spacer is primarily used to create proper and uniform spacing between rebars and concrete formwork on vertical surfaces. Below are the detailed methods for using this spacer:

Installation on Tie Rods (Stirrups):

The Wheel Fix Spacer is generally installed vertically on tie rods (stirrups). This method helps maintain appropriate spacing between rebars and the concrete formwork, ensuring uniform concrete coverage over the rebars.

Placement in Special Structural Conditions:

In specific structural situations, the round plastic cover (Wheel Fix Spacer) may also be placed on the main rebars. This is done to provide additional reinforcement and ensure proper spacing between the main rebars and the formwork.

Installation Steps:

Selecting the Appropriate Spacer Size:

First, choose the size and type of Wheel Fix Spacer based on the rebar diameter and the required concrete cover.

Placing the Spacer on the Rebar:

Position the Wheel Fix Spacer vertically on the rebar. Ensure that the rebar is securely locked into the central locking mechanism of the spacer.

Proper Spacing:

Install the spacers at defined intervals (usually according to the engineering specifications of the project) along the rebars. This spacing helps achieve uniform concrete coverage and prevents direct contact between the rebars and the concrete surface.

Monitoring Installation Strength:

Before concrete pouring, make sure all spacers are firmly and securely attached to the rebars and remain fixed in place.

By following these steps, you can effectively and efficiently use the plastic Wheel Fix Spacer to reinforce concrete structures and enhance the durability and strength of vertical concrete elements.
