JH/JHI - Masonry Joist Hangers
PRODUCT DESCRIPTION
The JH/JHI is the traditional timber - masonry hanger range. The higher side flanges help resist rotation while the wider masonry top flange spreads the loading over a greater surface area.
ADVANTAGES
Higher side flanges help resist rotation while the wider masonry top flange spreads the loading over a greater surface area.
MATERIAL

Hangers shown above are for 47mm joists, JHs are available in widths of 38, 44, 47, 50, 63, 75, 88, 92, 100, 125, 150 and 198mm.Standard return sizes available 100, 115, 125, 140 & 215mm.
ORDER DETAILS - JHR/JHIR - RETURN STYLE HANGERTo specify return style hangers add “R” to the standard JH product code.
Example(50 x 200 timber on 100mm blockwork)JH 50-200 with a 100mm return flange = JHR-50-200-100
ORDER DETAILS - JHST/JHIST - STRADDLE STYLE HANGERTo specify straddle style hangers add “ST” to the standard JH product code.
Example(2no. 50 x 200 timber on 100mm blockwork)JH 50-200 x (2) to suit 100mm blockwork = JHST-50-200-100
General Notes
Joist hanger must abut face of masonry wall to perform as quoted. Specifying return style hangers improves the chances of on-site compliance and produces a more robust detail.All hangers to suit timbers 150mm deep and above are manufactured with their H dimension 10mm undersize to allow for notching to provide a flush ceiling line.In order to achieve the stated safe working loads/characteristic capacities all masonry must be fully cured and a minimum of three block course (675mm) must be constructed above hanger. Where no masonry exists above see Cullen’s RA or RBJH.R dimension stands for return tab only and does not provide restraint.

ImportantParallel restraint is required for Joist Hangers, except the RA. For information on restraint refer to page 107.
ImportantIn order to achieve the stated safe working loads all masonry must be fully cured and a minimum of three block course (675mm) must be constructed above hanger before floor is loaded.
Fixing to Steel
Masonry hanger positioned on top flange of steelwork and fixed directly to top flange by shot firing (maximum steel fixing thickness 12mm) using:
- 4no. Spit Spitfire P370 Cartridge tool using SC9 nails or equivalent, into the hanger top flanges (2no. fixings per leg).
SAFE WORKING LOADS (kN) for all hangers 7.45kN - uplift 1kN.
Alternative fixing to shot firing, fix hanger top flange directly to top flange of steelwork using 4no. Tek screws.
SAFE WORKING LOADS (kN) for all hangers 6.90kN - uplift 1kN.
Fixing through top flange
Maximum gap from truss/joist to blockwork = 6mm
Rear face of hanger must tightly abut the blockworkGap = 0mm
