How many does a scaffold need?
A horizontal member along the wall that joins two standards and carries decks or guardrails. On ScaFix's example house (11.4 m × 5.3 m), the app's group “Ledgers and beams” has 120 pieces with Layher Allround, 156 with PERI UP and 0 with Layher Blitz. A straight 12.28 × 6 m wall takes 39 with Layher Allround.
Ledger in three systems
The example house scaffolded all round and three straight walls, each computed by ScaFix's engine with the system's own bay length and depth. The counts are the app's part group, which can also hold related parts (for example legs or base plates with the base jacks).
| System | Example house | 6.14 × 4 m | 12.28 × 6 m | 30.7 × 12 m |
|---|---|---|---|---|
| Layher Allround | 120 | 14 | 39 | 186 |
| PERI UP | 156 | 14 | 39 | 186 |
| Layher Blitz | – | – | – | – |
