Definition
High Chair Reinforcing refers to a chair-shaped device used to hold steel reinforcement in a specified position within a concrete slab while the concrete is being poured.
Purpose
High Chairs are used to ensure that reinforcing steel (rebar) remains in the correct position within a concrete slab, providing the necessary structural support once the concrete sets. Proper placement of rebar is crucial for the strength and durability of the concrete structure.
Examples of Use
- Concrete Slabs: Holding rebar at the correct height within the slab.
- Bridge Decks: Ensuring proper placement of reinforcement in bridge construction.
- Foundations: Maintaining rebar positioning in concrete foundations.
- Pavements: Supporting reinforcement in road and sidewalk construction.
Related Terms
- Rebar: Steel bars used to reinforce concrete.
- Spacer: A device used to maintain proper spacing between reinforcing elements.
- Concrete Cover: The distance between the surface of the concrete and the rebar.
Notes
High Chairs must be placed accurately and securely to maintain the integrity of the reinforcement during the concrete pour. They come in various heights and materials to suit different construction needs.
