Features

Material

Pre-galvanised mild steel

Benefits

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 support allowing superior performance.
Embossments on JHM stiffen top flange and holes allow improved mortar keying.
JHM side flange on deeper hangers is much higher than traditional style, providing greatly enhanced resistance to joist rotation.

1.The above Safe Working Loads are based upon product tests using four No. Hilti 12mm X-EDNI steel pins fired through the top flange material, onto a minimum 4mm thick steel plate. Other pins may be used provided similar structural performance is verified by the pin manufacturer. Pin Head size must be sufficient to prevent pull through during loading.

2.The designer must ensure that the steel support member will support the imposed loads.

3.Install shot-fired pins in accordance with manufacturer’s instructions

Installation

Standard Masonry Installation

Use all specified fasteners. See "General Notes".
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 ABOVE 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.

Fixed to Steel Beams

The JHM range can be mechanically fixed to steel beams of
thicknesses up to 12.5mm.
Timber is required in the web of the ‘I’ section steel beam when
the hanger depth is less than the steel depth.
Timber must be flush with the outer edges of the ‘I’ section steel
beam.
The shot-fired pins must be installed by a qualified person in accordance with the manufacturer’s installation requirements.

Options

Return configuration provides additional support by wrapping around three sides of the block. Designate "return" and length of return dimensions when ordering.
JHM, JHMR OR JHMS HANGERS DO NOT SATISFY THE REQUIREMENTS FOR LATERAL RESTRAINT TYPE HANGERS UNLESS STRAPS ARE FITTED.
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.
Other widths and heights available to order. Contact Simpson Strong-Tie® for details.
SPEC JHM’s up to 61mm width can be skewed from 5 to 45 deg. See skewed hanger load table.
