Joist Hanger for Masonry: I-Joists

The JHM and JHMI range of joist hangers can be used to connect solid sawn
joists, trusses and engineered joists to masonry walls or steel beams.

Product Details

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 top flange, and holes, allow improved mortar keying.
  • Flanges on hangers are much higher than traditional style, providing greatly enhanced resistance to joist rotation.
  • Can be installed onto ‘I’ section or hollow section steel beams.

Mechanically Fixing to Steel

Application

Options

  • Return configuration provides additional support by wrapping around three sides of the block. Designate "return" and length of return dimensions when ordering.
  • JHMI, JHMIR OR JHMIS 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.

1.The above Safe Working Loads are based upon product tests using four No. Hilti 12mm X-EDNI steel pins fired through holes provided in the top flange of the hangers onto 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.

Ínstallation

Standard Masonry Installation

  • Use all specified fasteners. See table.
  • Hanger must be installed so that the back flange is tight against the face of the supporting member.
  • 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 JHMI 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.
