JHMs are one piece non-welded joist hangers for supporting timber joists, beams and trussed rafters from masonry walls.
Built -in inspection slot at the base of the hanger to aid inspection from the ground.
Top flange provides widest area in contact with masonry supportallowing superior performance. Embossments on JHM stiffen top flange andholes allow improved mortar keying.
JHM side flange on deeper hangers is much higher than traditionalstyle, providing greatly enhanced resistance to joist rotation.
Regularised Timber: we have added new sizes to our JHM range to suitregularised timber. Use 47mm or 91mm width hangers for this newapplication.
Pre -galvanised mild steel.
- Use all specified fasteners.
- Set hanger back flange tight against block wall when built to desired level, then continue with additional courses to complete wall height. Joist should be tight into back of hanger when possible. Maximum gap permitted is 6mm.
- Minimum 3 courses of solid block (675mm masonry) required abovce hanger, with mortar fully cured before applying load.
- Do not stack blocks or heavy loads on the joists during construction unless the joists have additional support to take the full load of the blocks vertically and horizontally.
- The JHM joists hangers can be fixed to steel beams by means of power actuated fasteners.
- The shot -fired pins must be installed by a qualified person in accordance with the manufacturer’s installation requirements.
- Return configuration provides additional support by wrapping around three sides of the block. Designate “return” and length of return dimensions when ordering.
- Return hangers do not satisfy the requirements for lateral restraint type hangers.
- Straddle configuration provides two hangers connected across top of support enabling exact alignment on both sides of supporting wall. Designate “straddle” and length of straddle dimensions when ordering.
- JHM can be shot -fired into steel.
- JHM’s up to 61mm width can be skewed from 5 to 45 deg.
