A4 Push-pull props
Push-pull props and kicker braces are
used for aligning the TRIO formwork,
for stability and for support against
wind forces.
The choice of the correct prop and
brace is made according to the
formwork height.

PERI Push-Pull-Props and Kicker Braces
*If necessary, the distance from top of formwork must be adapted to the system.
A maximum force of 11.3 kN is to be led into the building at the foot of the push-
pull-prop for the given width of influence.
Wind loads: h < 8 m = 0.5 kN/m

8 m < h < 20 m = 0.8 kN/m
