Bolster

Definition

A long wire type "chair" used to support reinforcing bars in a concrete slab while the concrete is being placed.

Purpose

Bolsters are essential in concrete construction to maintain the correct position of reinforcing bars (rebar) within the slab, ensuring that the rebar remains properly embedded in the concrete for structural integrity and strength.

Examples of Use

• Using bolsters to hold rebar in place when pouring a concrete foundation.
• Supporting reinforcing bars in the construction of concrete floors and driveways with bolsters.
• Applying bolsters in large-scale commercial and industrial concrete projects to maintain rebar alignment.

Related Terms

• Rebar: Reinforcing steel bars used to strengthen concrete.
• Concrete Slab: A flat, horizontal surface of concrete, commonly used in floors and foundations.
• Reinforcement: The process of strengthening concrete by embedding steel bars or mesh within it.

Notes

Proper placement and secure fastening of bolsters are crucial for maintaining the structural integrity of the concrete slab. Different types and sizes of bolsters are available to suit various construction needs.
