Joist hangers give roofing carpenters a great deal of flexibility. They are relatively easy to level in, fix very strongly indeed and allow the carpenter (by using temporary fixings) to get all timbers in place, with the correct spacing in between them, before fixing permanently.

The Simpson Strongtie JHA450/150 Joist Hanger Jiffy is a one-piece, non-welded steel Jiffy, perfect for joining timber. It is used by trade professionals. The Joist Hanger has a wide strap and increased nail spacing, giving it a larger surface area to work with. The jiffy has a speed-prong so you can temporarily attach it, to allow your hands to get the tools to fix it to the timber. Supplied as a single unit. Features and Benefits: The hangers above are known as a jiffy hangers. This type of hanger is used only when abutting one timber to another. It comes with plenty of holes through which you can screw or nail the hanger to one timber while you drop another timber in the "shoe". Rotten ends of joists can be cut off and replaced with new sections Fixing Joists to an RSJ (Rolled Steel Joist)To acheive ultimate lifespan of wood joists, a Joist Hanger is the best solutions as it will preserve the wood joists to which they are attached, as over time the wood will naturally twist and move. Josit hangers ensure the wood beams keep a true fitting, ensuring long term strength and rigidity. When a large span has to be covered (usually in a roof space) it is practical to insert an RSJ across two load bearing walls to break the long span into shorter distances. This allows the support from the floor to be minimal leading to greater sized rooms. Fixing joists to RSJ’s however, is not so easy without joist hangers. In may 1957 however, A James Findleton Roland decided to submit a patent for the improvement of the first hanger. It is not clear why both patents were granted on a design that is very similar and does the same job. The only difference we can see is that Mr Roland came up with the idea of using joist hangers in a saddle fashion.

It can also allow water to soak into the end grain of the timber where it can go undetected before it rots. Please see our projects on repairing timber joists for more information on what to do when you suspect rot has got into your joists. One final type of joist or beam hanger is called the Concealed Bean Hanger and it acts a little like a mortise and tennon joint where two beams or joists are to meet at right angles and the fixing is not to be seen.

Specification

Bear in mind also that the load tolerances for each will vary depending on the materials that you use. Please be careful only to cut enough of a chase to push one hanger in at a time. If you cut a long chase you are weakening the wall considerably so mark out exactly where you need the hangers and just cut out for each individual hanger. Prices for products are liable to change at any time, but changes will not affect contracts which have come into force. The Concealed Beam Hanger allows two timbers to be joined with no visible fixings making it ideal for the refurbishment of old cottages and period buildings. To all intents and purposes, each concealed beam hanger is a dowelled mortise joint.

For loft conversions or where a floor is being constructed at different levels, long-leg hangers have an extended drop. The length is easily adjusted by bending over the legs at the desired depth. Long-leg jiffy hangers feature a location tab that allows for easy alignment once installed.

Once the timbers have been bolted into the RSJ, joist hangers (in this case saddle joist hangers) can be hung over the RSJ and face-fixed to the timbers. This allows the easy installation of the joists as seen below.

Load is always the first consideration when buying jiffy hangers. In addition to determining size, it may also determine the type. Our S impson face fix joist hangers, for example, will typically support a lesser down load than a top-flange mount. They won’t demand the same sort of access requirements that a top-flange hanger will. 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. The patent was for a simple steel construction that has not changed a great deal since.
