  3. Skew angle to be specified in accordance to the illustration.

Installation

Installation

Installation

Build the masonry to the required level and leave to cure.

  • Place hangers onto supporting block work, ensuring the hanger back flange is tight against the face of the block work.
  • Continue with masonry above hanger ensuring a minimum of 675mm of masonry is above the hanger top flange and leave to cure.
  • Mortar must be fully cured before any load is applied to the hanger.
  • Install the joist into the hanger. The joist should be tight into the back of the hanger. A maximum gap of 6mm is permitted.
  • Fix the joist to the hanger using all specified fasteners.
  • If installing I-joists, web stiffeners are required. Web stiffeners should be installed in accordance with I-joist manufacturers recommendations.
  • Where the 90˚ skewed variant is used to frame around soil vent pipes, a solid blocking piece is to be fitted between the joist and hanger back flange so the joist is positioned 50mm from the face of the masonry wall.
  • The blocking piece must be fitted to the joist prior to installing into the hanger. The blocking piece must be the same depth as the joist, the width to suit the remaining gap, and be at least 100mm long.

Options

How to Order

  1. Specify hanger finished height and width.
  2. Specify skew angle and direction - Left or Right

Example:

For joist 200mm deep by 100mm wide with a right directional skew of 45˚ the code to order would be: RHMSK200/100 SKR45.
