In the arena we typically play in, we most often use joist hangers when building or providing maintenance to decks or porches.
While always being incorporated into a new deck or porch that we are building, it is not unusual for us to come across an older deck or porch where there is an absence of joist hangers, most probably because that particular deck or porch was built prior to the widespread use of joist hangers within our industry.
When we come across these situations, it is most prudent to install the joist hangers wherever possible.
What exactly are ‘joist hangers’?
Joist hangers are metal brackets designed to hold wooden joists in place. They are essential components in construction, providing support and ensuring the structural integrity of buildings. These devices are widely used in floor, ceiling, and decking applications.
Joist hangers are made from galvanized steel to prevent rust and corrosion. Their U-shaped design is simple but highly effective. The open ends of the U wrap around the joist, while the flat bottom and sides attach to a supporting beam or structure using nails or screws. This setup creates a strong, stable connection, distributing the weight of the joist and the load it carries across the support beam.
Builders use joist hangers when constructing floors, ceilings, decks, and roofs. For instance, when creating a deck, joist hangers connect the horizontal deck joists to the vertical beams, providing stability and strength to the structure. Without them, the joists might shift, sag, or even collapse under heavy weight.
Using joist hangers offers several advantages. First, they save time during construction. Installing a joist hanger is faster than other traditional methods, such as notching beams or constructing wooden supports. Second, joist hangers improve safety by ensuring the joists remain firmly in place over time. They also help reduce the risk of squeaky or uneven floors caused by loose connections. Additionally, joist hangers can be used in various weather conditions, as they resist corrosion and can withstand outdoor environments.
However, it is important to choose the right type of joist hanger for each job. Joist hangers come in different sizes and shapes to match various wood sizes and project requirements. Heavy-duty joist hangers are available for supporting larger loads, such as in commercial buildings or industrial projects. When purchasing joist hangers, builders should also consider the type of nails or screws to use, as they are key to ensuring the hanger’s strength.
Proper installation of joist hangers is crucial. To begin, the hanger is placed where the joist meets the supporting structure. The builder must align it carefully to ensure the joist is level. Next, nails or screws are inserted into the pre-drilled holes on the hanger to secure it tightly. Over time, regular inspections should be performed to check for signs of wear or damage.
Joist hangers are a vital part of modern construction. They provide a reliable, efficient, and long-lasting way to secure joists. With their use, builders can create strong, safe, and stable structures that stand the test of time. Whether for small home projects or large commercial buildings, joist hangers are a smart choice for ensuring construction success.
