- How ScaFix plans Japanese frame scaffold
- 1.7 m lifts; ties every 9 m vertically, every 7.32 m (4 × 1.83 m) / 7.62 m (5 × 1.52 m) / 7.31 m (6 × 1.22 m) along the wall; diagonals at least one per 1 bays in every lift
Wall-tie spacing along the wall for Japanese frame scaffold
ScaFix ties Japanese frame scaffold every 9 m in height. Along the wall a tie sits on a standard, so the spacing is always a whole number of bays: for a wall built from one bay length, the table shows how many bays lie between two tied standards and the spacing that gives. Rule: 労働安全衛生規則 §570 第1項第5号 (枠組足場: 垂直方向 9 m、水平方向 8 m 以下). ScaFix is a planning tool, not a structural approval.
| Bay length | Bays between ties | Tie spacing along the wall |
|---|---|---|
| 1.83 m | 4 | 7.32 m |
| 1.52 m | 5 | 7.62 m |
| 1.22 m | 6 | 7.31 m |
| 0.91 m | 8 | 7.31 m |

Pick Japanese frame scaffold if…
- you need a wide working deck: ScaFix plans Japanese frame scaffold up to 1.22 m deep, a width only 8 of the 60 other systems of its type also reach.
- space along the wall is tight: Japanese frame scaffold comes as narrow as 0.61 m.
- you build in lifts of 1.7 m: that is this system’s lift height in ScaFix, against 2 m for most systems.
