Ribband

Definition

A ribband is the support for the second-floor joists of a balloon-frame house. It is the horizontal member of a wood frame wall that supports floor joists or roof rafters.

Purpose

The purpose of a ribband is to provide structural support for floor joists or roof rafters in balloon-frame construction, ensuring stability and load distribution.

Examples of Use

• In balloon-frame houses, ribbands support the second-floor joists, connecting them to the wall studs.
• Ribbands are used in roof construction to support rafters and distribute loads evenly across the structure.
• In multi-story buildings, ribbands help to stabilize the framework and provide a solid base for upper floors.
