The Parkes joist hanger ranges offer very strong and effective methods of supporting timber joists, built in to brick or block walls. They can also be used in timber to timber connections as well as attaching joists to steel beams. Appropriate fixings and methods should always be used.
- The joist hanger should have a minimum of 3 courses (675mm) of solid block work on top of the joist flange, and any masonry above or below the hanger must be fully cured before any load is added.
- The back plate of the hanger must be tight and flat against the wall.
- Timber Joists must be cut accurately to ensure a tight fit against the hanger back plate (a maximum gap of 6mm is permitted) before being fixed using 30mm x 3.75mm galvanised square twist nails, or equivalent.
Parkes welded joist hanger – Traditional design that is excellent for both new build and retro. fitting, due to its contained width the hanger can be fitted quickly and also flush against obstacles.
Parkes welded hookover hanger – The addition of the hookover plate does not increase any weight loadings. It does however allow for single user installation, as all hangers can be positioned quickly and left in place while you continue the build.
The depth of the hookover plate must be specified at time of order.
Parkes welded straddle hanger- Again the addition of the straddle plate offers no extra weight loading capacity but does once again allow for single user installation. It also ensures the twoconnected hangers align exactly on either side of the supporting wall.
The depth of the straddle plate must be specified at the time of order.
- Parkes welded joist hangers are manufactured from mild steel and galvanised after manufacture.
- All the joist hangers within these two ranges of 150mm deep and above are manufactured 10mm less than overall size to allow for notching and for regularised timber.
