Most joist hangers slot over or under the edge of a wooden beam around three sides, and are attached with nails. There is a connecting plate on the joist hanger that is fastened to the surrounding frame. Joist hangers are versatile and are much stronger than using traditional nails or screws alone. They are also easier to fit and relatively cheap given the length of time they will last. Provided all the holes have nails or screws inserted, they provide excellent stability. Joist hangers can also be welded if needed and can be attached to masonry as well as timber.
all there are two main types of Joist Hanger applications
- Timber to Timber
- Timber to Masonry
These hangers are used in timber to timber applications due to them having a greater load capacity.
The masonry hanger or Cullen JHI Hangers are especially used in Timber to Masonry applications, and can be built into the wall during construction, or the wall or mortar joint can be cut out to install the masonry joist hangers. These are most used between walls where the building in of the timber joist is not possible or not acceptable due to air tightness requirements.
