Framing construction, essential for building structures, primarily involves light, heavy, and expedient framing, with light framing having the most variety for residential construction. Let's delve into the types of framing focused on light structures:
Light Framing Types
According to the provided reference, there are three principal types of framing used for light structures:
- Western Framing (Platform Framing):
- This is the most commonly used method today.
- Each floor is built as a separate platform.
- Wall studs run only from one floor to the next.
- Easier to erect as it provides a working platform as each floor is completed.
- More fire-resistant as fire breaks are created at each floor.
- Balloon Framing:
- Wall studs run continuously from the foundation to the roof line.
- Floors are hung from the studs.
- This method is less common now, mostly used in older structures.
- Requires longer lumber for studs, increasing cost.
- Can create a fire pathway up through the walls if not properly fire stopped.
- Braced Framing:
- Older framing method.
- Uses large posts and beams that support the frame.
- Requires diagonal bracing to provide strength and stability against lateral loads.
- Not widely used in modern construction.
Framing Types Summary
Here's a table summarizing the three main types of light framing construction:
| Type of Framing | Description | Key Characteristics | Common Usage |
|---|---|---|---|
| Western (Platform) | Each floor is built as a separate platform. | Studs run floor to floor, creates fire stops | Most Common, modern residential construction |
| Balloon | Wall studs run continuously from foundation to roofline. | Floors are hung from the studs, longer studs required | Older structures |
| Braced | Uses large posts and beams, diagonal bracing for stability. | Requires significant bracing, less common in modern residential projects | Older structures, less common in modern buildings |
Additional Insights
- Framing Materials: While not specified in this reference, these different types of framing use materials like lumber, and sometimes steel.
- Nomenclature and Location: Figure 6-1 on page 6-2 (according to the source) illustrates the nomenclature and location of the various members within these framing systems, including studs, joists, and rafters.
In conclusion, the three principal types of framing for light structures are western (platform), balloon, and braced framing. Western framing is the most popular choice in modern construction, while balloon and braced framing are more commonly found in older buildings.
