In this article, we will explore this topic in detail and provide insights into this common construction scenario.
Understanding Deck Hangers:
Before delving into the use of deck hangers on an angled beam, it’s crucial to understand their purpose and how they function. Deck hangers, also known as joist hangers, are metal brackets that provide support, stability, and connections for deck joists. They are typically made from galvanized steel to ensure durability and resistance to corrosion.
Traditional Use on Horizontal Beams:
Deck hangers are designed to be used with horizontal beams, as this provides the most straightforward and efficient process for deck installation. They are installed by attaching them to the side of the beam using nails, screws, or other appropriate fasteners. This allows the joists to rest in the hangers, creating a secure connection that supports the weight of the deck.
The Challenge of Angled Beams:
In some construction scenarios, builders may need to accommodate angled beams due to architectural choices, site constraints, or structural requirements. However, using deck hangers on an angled beam presents a challenge. The nature of deck hangers makes it difficult to achieve a secure connection and maintain the necessary stability when dealing with non-horizontal beams.
Potential Solutions:
While using traditional deck hangers on an angled beam may not be feasible, several alternative solutions can be explored. These solutions include:
1. Adjustable Angle Hangers:
Some manufacturers produce specialized adjustable angle hangers designed specifically for use on angled beams. These hangers allow builders to adjust the angle to match the slope of the beam, providing a secure connection point for the deck joists. However, it’s important to note that these specialized hangers may not be available in every market, so sourcing them may be limited.
2. Notching or Cutting the Decking Material:
Another potential solution is to notch or cut the decking material to match the angle of the beam. By doing so, the deck hangers can be attached to the side of the beam as usual, using the notched or cut decking material as a support. However, this approach requires careful cutting and precision to ensure a proper fit and maintain the strength of the deck structure.
3. Custom Fabrication:
In cases where standard deck hangers or adjustable angle hangers are not suitable, custom fabrication might be the solution. Builders can work with a metal fabricator or engineer to create custom hangers that are specifically designed to accommodate the unique requirements of a deck built on an angled beam. However, this option may increase the complexity and cost of the project.
Consulting with Professionals:
When confronted with the challenge of constructing a deck on an angled beam, it is crucial to consult with professionals to ensure the structural integrity and safety of the deck. Architects, structural engineers, or experienced deck builders can provide valuable insights, recommendations, and alternatives based on the specific project requirements.
While deck hangers are primarily designed for use on horizontal beams, alternative solutions can be explored when dealing with angled beams. Specialized adjustable angle hangers, notching or cutting the decking material, and custom fabrication are potential approaches to overcome this challenge. Consulting with professionals is essential to ensure proper construction techniques are employed, maintaining the safety and structural integrity of the deck.
