This allows fixing from the top also, giving extra support. The lighter joist hangers, or Jiffy Hangers, are always provided with fixing holes to allow you to fix them to the face of the wall but usually also have long "legs" which allow the hanger legs to be bent over, or "wrapped over" the wall. Thanks to Simpsons Strongtie for many of these images, there is a link to them further down the page if you would like to find out more about them.įace fix Jiffy hangers can have long legs to provide plenty of fixing options Face Fixed Jiffy Hangers
One of the largest suppliers of Joist hangers of all kinds in the UK is a company called Simpson Strong Tie who have adapted their range to now include special galvanised brackets, called Simply Build It, for putting together shelves and workbenches. They are galvanised to prevent rusting and can be fixed, where fixing is necessary, with either screws or nails. In reality, most joist hangers are a little of both. Those which are fixed to the face of the wall which is to support the joists, and those which literally hang on the top of the wall that carries the joists. Joist hangers (or rafter hangers or joist brackets as they are also known) are usually divided into two categories. Ceilings, roof, floor joists and even decking could now be laid in a “jiffy” rather than the hours it took to build the end of the joists into the walls, or form the correct joint in adjoining timbers. However, the patent was granted and joist hangers became the go-to product for the simplicity they offered in building. The only difference we can see is that Mr Roland came up with the idea of using joist hangers in a saddle fashion. It is not clear why both patents were granted on a design that is very similar and does the same job.
In may 1957 however, A James Findleton Roland decided to submit a patent for the improvement of the first hanger. Since 1903 roof and ceiling joists can be erected in a jiffy The patent was for a simple steel construction that has not changed a great deal since. Joist hangers were first invented in 1903, or at least that’s when the first patent was filed, by August H Eberhabdt of California USA. Why are Joist Hangers Called Jiffy Hangers and who Invented Them?
