Plumbing accessories brace the formwork against wind loads and make it easier to plumb and align.

|
WARNING Risk of the formwork tipping over! ➤ Formwork elements must be held stable in every phase of construction work! ➤ Observe all applicable safety regulations! ➤ If high wind speeds are likely, and when work finishes for the day or before prolonged work-breaks, always take extra precautions to fix the formwork in place. |

The values apply where the wind pressure we = 0.65 kN/m2. This results in an impact pressure qp = 0.5 kN/m2 (102 km/h) where cp, net = 1.3. The greater wind loads encountered at exposed formwork-ends must be restrained by additional plumbing accessories (e.g. struts or pipe-braces). In cases where higher wind pressure is encountered, the number of struts must be determined by statical calculation!

Note:
Every gang-form must be supported by at least 2 plumbing accessories.
Example: Where the formwork height is 5.50 m, the following are needed for every 4.00 m wide gang-form:
▪ 1 panel strut 340
▪ 1 panel strut 540
