Proper Construction Techniques for Beams and Joists

When building a house, it is crucial to understand the proper techniques for constructing beams and joists. This guide will explain the correct methods to ensure structural integrity and safety.

Understanding the Components

In house construction, several critical components must be installed correctly to ensure the building's stability and safety. Two of these components are beams and joists. Beams are horizontal structures that support loads and transfer them to columns or walls, while joists are the horizontal supports that act as a floor or roof system's structural members.

Beams and Atomic Hangers

Beams should rest directly on a haunch, which is a concrete or wood extension that provides a solid, level foundation. This is the recommended and most common method to attach beams. However, some may consider using top flange hangers or face hangers. These techniques can be dangerous and unnecessary, as they add unnecessary expenses and potential risks during inspection.

Why Using Beams with Top Flange Hangers is Inefficient

When beams are hung with top flange hangers off the sill plate, it not only adds extra work and material expenses, but it also increases the risk of structural weakness during inspections. This is because the union between the beam and the sill plate is no longer a solid connection. Instead, it relies on the hangers, which may not provide the same level of support as a direct rest on a haunch.

Using Joists with Top Flange Hangers

Similarly, using top flange hangers to hang joists off the sill plate is also not recommended. While this method might seem convenient at first glance, it can lead to several issues. For instance, the joist hangers may not distribute the load evenly, leading to misaligned beams and potential building collapse. Moreover, the method requires a significant amount of extra labor and materials, making it less cost-effective than standard construction techniques.

Using Face Hangers for Beams

Face hangers are another issue. These are often used to hang beams where the top flange or the wider section of the beam is faced down instead of resting on a haunch. This method is problematic as it does not provide a solid, level foundation for the beam. Furthermore, face hangers can cause the beam to shift or move, leading to structural instability and potential collapses. It is best to avoid using face hangers and stick to traditional methods that ensure the integrity of the beam and its supporting structure.

Conclusion

When building a house, it is vital to follow proper construction techniques to ensure the integrity of the building and maintain safety standards. Beams should rest directly on a haunch, and joists should be properly supported and anchored using standard hangers or other appropriate methods. Avoiding unnecessary and potentially harmful techniques like top flange hangers and face hangers can save time, money, and prevent structural issues.

Additional Tips

To further ensure the safety and longevity of your construction project, consider the following tips:

Select high-quality materials and ensure they are properly installed. Secure all connections and joints to prevent any movement or shifting. Regularly inspect the structure to identify and address any potential issues before they become serious. Consult with a professional if you have any doubts or questions about the construction process.
