difference between slipform and jumpform

What is the difference between slipform and jumpform?

 

[Ingy]

Slipform - concrete is placed continuously in side form which moves at a set rate. Forms are not removed, they slip over the concrete which can support itself by the time it is out of the form. I think of a slipform as a "concrete extrusion."

Jumpform - As the name implies, the wall form is jumped from one lift to the other. The system is supported by the lower lift of concrete. Forms are released and stripped after the concrete has adequately cured. Embeds are provided in the concrete to receive the form system when it is jumped up to the next level.

Try looking up on the web sites for Doka, Peri, Symons, Patton.

How does climbform work?

 

[Zambo]

I think climbing forms are what you are looking for rather than jump forms. What are you constructing? There are many cases where a choice has to be made between slipform and climbing forms.

As stated above you should contact Doka, Peri, RMD who all have climbing formwork systems. Inserts are cast into the top of the preceeding lift which will be used to support the formwork for the subsequent lift. There may also be a simple mechanism bult in which will allow the formwork to be tilted back by a few degrees to make cleaning the formwork easier.
