Flat bar Spacer

Flat bar Spacer

Double-Layer Spacer for Soft and Recessed Surfaces

The Flat bar Spacer is an ideal component for creating concrete covers and placing rebar on soft and recessed surfaces such as foam-covered floors (e.g., polystyrene foam). A special feature of this spacer is its ability to accommodate two perpendicular or crossed rebar layers within its central cavity. This spacer is particularly well-suited for use at the intersection points of rebar, a feature made possible by the differing heights of its two intersecting seating areas. The Flat bar Spacer can withstand point loads ranging from 120 to 150 kg and can hold rebar sizes from 8 mm to 16 mm within its locking arms.

Creating a concrete cover for rebar on soft and recessed surfaces is essential to prevent the spacer from sinking and disturbing the uniformity of the rebar spacing with the floor. Therefore, the Flat bar Spacer is a specialized product with a larger cross-sectional area compared to similar spacers (such as the Flat Fix Spacer), making it more effective in these applications.

This plastic cover for rebar is designed to hold rebar securely during concrete pouring. Its narrow and flat design is typically used in projects where rebar needs to be placed on a flat and uniform surface. The use of this spacer plays a crucial role in enhancing the durability and strength of concrete structures and can improve the quality and efficiency of the pouring process.

Features of the Flat bar Spacer

• Capable of withstanding a point load of 120 to 150 kg
• Can accommodate rebar sizes from 8 mm to 16 mm
• Ideal for intersections of rebar

How to Use the Flat bar Spacer

The Flat bar Spacer is specifically designed to be placed at rebar intersections, and it is not recommended for use in other areas where it would be less effective or cost-efficient.

Consumption Rates for the Flat bar Spacer

1. Normal Weight Surfaces:
   • Use 4 spacers per square meter for normal weight surfaces.
2. Heavy Weight Surfaces:
   • If the rebar network uses larger diameter rebar or if the reinforcement density is too high for the standard 4 spacers per square meter to be sufficient, the exact number of spacers should be calculated based on the weight of the rebar network and the point load capacity of the spacer.

Important Notes Regarding the Flat bar Spacer

• The Flat bar Spacer is specifically designed for use on soft and recessed surfaces, such as polystyrene blocks.
• The most suitable placement for the Flat bar Spacer is at the intersection of rebar.
• It is not suitable for use on standard concrete surfaces or molds, as its relatively large cross-sectional area and level surface could cause structural weaknesses.
• If the rebar network is unusually heavy, it is recommended to use alternative horizontal spacers like the Hardfix Spacer between the soft and recessed surface spacers to better distribute the load.
