1.1 When to use Masonry Support SystemsMasonry and brick panels must be restricted in size to avoid facade cracking due to differential expansion and compressive stress fracturing. Differential expansion is caused by thermal fluctuationsandmoistureabsorption.Qwik-Fix™recommendsmasonrysupportanglesshouldbe provided at every single or second storey level when a building exceeds 9 metres in height. For masonry panel design guidance please refer to BS 5628: Part 1: 2005 or the IStructe manual for eurocode 6.

1.3 Design considerations1.3.1 Fixing and restraint considerations
the minimum expansion gap should be at least 12mm where there is a single storey height of brickwork below the support system. the gap should be increased by 1mm for every additional metre in panel height.
Wall ties should support the panel no more than 300mm above and below the shelf angle.

AllstandardQwik-Fix™Angleconfigurationsaresuitableforcavitywidthsrangingfrom70mm to 200mm. Brackets for narrower cavities can be fabricated on a case by case basis. When designing for cavity widths greater than 150mm in width, we recommend you contact the Qwik-Fix™ technicaldepartmentfordesignassistanceonfixingdetails.

Qwik-Fix™ angle is suitable for use with most outer leaf materials: brickwork, fairface blockwork, rendered blockwork, exterior insulation panels, cut stone and reconstituted stone.
calculating loads:
Masonry load assumptions for Brick, Block & render below are per BS 648 (1964). Qwik-Fix™ recommends referring to manufacturers guidelines for exact values.
* Factored Panel Load = (Unfactored Characteristic Load x 1.4 Factor of Safety)
an overall partial safety factor for action of g = 1.4 is used. the partial safety factors for action depend on the type of loading and shall be taken from the national regulations. according to the British national annex of eurocode: Basis of Structural Design (BSen1990), the partial safety factor is gg = 1.35 for permanent actions and gQ = 1.5 for variable actions.

Qwik-Fix™ gFrP cavity ties have been independently tested and conform to BS en 845-1: 2003 and meet the appropriate parts of the nHBc standards at a cavity width of 200mm. they can be cat-egorised as type 2 ties at a design embedment of 62.5mm in accordance with corrigendum no. 1: BS 5628-1: 2005. this means they can be used in buildings not exceeding 15m in height, anywhere in Ireland or the uK.
It is assumed that masonry units conform to BS en 771, with a normalised compressive strength > 5n/mm² and mortar conforms to BS en 998-2, with a compressive strength > 1.5n/mm².
