How many does a scaffold need?
An adjustable screw jack under each standard that levels the scaffold on the ground or on a base plate. On ScaFix's example house (11.4 m × 5.3 m), the app's group “Base jacks and legs” has 34 pieces with Layher Blitz, 64 with Layher Allround and 40 with PERI UP. A straight 12.28 × 6 m wall takes 12 with Layher Blitz.
Base jack 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 Blitz | 34 | 8 | 12 | 24 |
| Layher Allround | 64 | 12 | 20 | 44 |
| PERI UP | 40 | 6 | 10 | 22 |
