Demystifying Joist Supports: What Are They Called?
Brief Summary
While the term “joist hanger” is the most common and technically accurate, other names exist depending on specific design or function, such as beam hangers, rafter hangers, or even just “hangers.” All, however, serve the primary purpose of providing secure support and connection points for joists within a structural framework.
Expanded Answer
Joist Hangers: The Go-To Solution
- Function: Joist hangers are metal connectors specifically engineered to support the ends of joists where they meet a beam or ledger board. They ensure a secure and load-bearing connection, transferring the weight of the floor or ceiling structure to the supporting members.
- Design & Variety: Joist hangers come in various sizes and configurations to accommodate different joist dimensions and load requirements. They typically feature a U-shaped or L-shaped design with multiple nail or screw holes for secure attachment.
- Material: Most joist hangers are made from galvanized steel for strength and corrosion resistance. Stainless steel or other specialized coatings may be used in specific environments or applications.
Other Names for Joist Supports
- Beam Hangers: When used to connect joists to beams, they may be called beam hangers. These hangers are typically larger and heavier-duty than standard joist hangers to handle the increased loads.
- Rafter Hangers: In roof framing, similar metal connectors are used to secure rafters to ridge beams or wall plates. These may be referred to as rafter hangers or rafter ties.
- Hangers (Generic): In casual conversation or general construction terminology, joist supports may simply be called “hangers.” However, this term lacks specificity and may refer to other types of connectors as well.
Importance of Proper Joist Support
- Structural Integrity: Joist hangers are critical for maintaining the structural integrity of floors and ceilings. They prevent joists from slipping or twisting, ensuring a safe and stable framework.
- Building Code Compliance: Building codes in the USA mandate the use of approved joist hangers and specify their proper installation to meet safety standards.
- Load-Bearing Capacity: Different joist hangers have varying load capacities based on their size, design, and material. It is crucial to select the appropriate hanger for the specific application and load requirements.
Installation & Trends
- Proper Installation: Correct installation is essential for ensuring the effectiveness of joist hangers. This includes using the correct nails or screws, ensuring proper alignment and seating of the joist, and following manufacturer’s instructions.
- Remodeling & Renovations: When modifying or extending existing structures, joist hangers provide a convenient and code-compliant way to connect new joists to existing framing members.
- Innovation & Trends: Advancements in building technology have led to the development of specialized joist hangers for various applications, such as seismic-resistant hangers and adjustable hangers for sloped ceilings.
Conclusion
While several terms may be used to describe joist supports, “joist hanger” remains the most accurate and widely recognized. These metal connectors are crucial for ensuring the structural integrity and safety of floors and ceilings in both new construction and remodeling projects. By understanding their function, types, and proper installation, you can make informed decisions for your construction or renovation project.
