Cavity Width
All standard Qwik-Fix™ Angle configurations are suitable for cavity widths ranging from 70mm 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 technical department for design assistance on fixing details.
Loading
Qwik Fix™ Angle is supplied in configurations to accommodate design loads ranging between 1kN/m and 20kN/m.
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 per BS 648 (1964):
| Material | Density kg/m³ | Unfactored Panel Load kN/m² | *Factored Panel Load kN/m² |
| Blockwork & Medium Density Clay Brickwork (100mm wide) | 2150 | 2.15 | 3.01 |
| Blockwork & Medium Density Clay Brickwork (215mm wide) | 2150 | 4.62 | 6.50 |
| Sand & Cement Render (12.7mm thick) | 1888 | 0.24 | 0.34 |
| High Density Clay Brickwork | 2327 | 2.33 | 3.30 |
* Factored Panel Load = (Unfactored Characteristic Load x 1.4 Factor of Safety)
Design Load (kN/m) = [Factored Panel Load (kN/m²) x Panel Height (m)]
| Factored Load Range (kN/m) | Specify As Follows: |
| 1 – 2 | K02 - [Insert Cavity Width] |
| 3 – 4 | K04 - [Insert Cavity Width] |
| 5 – 6 | K06 - [Insert Cavity Width] |
| 7 – 10 | K10 - [Insert Cavity Width] |
| 11- 12 | K12 - [Insert Cavity Width] |
| 13 – 14 | K14 - [Insert Cavity Width] |
| 15 – 16 | K16 - [Insert Cavity Width] |
| 17 – 18 | K18 - [Insert Cavity Width] |
| 19 – 20 | K20 - [Insert Cavity Width] |
