Re: Tilt-up Pancake

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Keep in mind that the lifting operation may be a bit more complicated, with the bottom edge of the panel being lifted tending to slip off the edge of the stack.   (Of course that's the builder's problem.)

And be ware of the possibility of settlement and/or distress in the floor slab on which this big, heavy stack is being built.  It's a significant superimposed load on the slab.

Yes, it is possible to stack panels/forms, but I've only done it for 2 layers, not 4 - 5.

It was required because the footprint of the building relative to the height of the walls was small.

To do this, the main thing is using threaded inserts (ferrule's or similar) for slab dowels and other items and planning of the lift sequence (contractor's problem, but you should think about it). You may also have to do some blind lifts which the crane guys try to avoid.

In sites where there are space constraints and tilt up construction is desired, is it possible to "Pancake" the panels?
That is form and pour a first panel (layer), then wait sometime and pour and another panel (layer) on top it and so on (up to say 4 or 5 layers).
If you have experience or thoughts on such a process, please share it with us.
