Concrete panel silage clamps

Location
West Wales
Just trying to get my head around using panels as walls for a clamp instead of shuttering it. I
Assume you can fit a panel between webs and then use it for 2 clamps in effect?
Do the clips get in the way when filling and grabbing out?
Do they Tare the side sheet?
Do you still side sheet it all or just enough for a top overlap?
Anyone done one recently with a guide on the price for the stanchions?
And finally is 20ft a no go on them? Our 95mm panels flex like hell if your mucking out.

They want to be 6” at least and double loading. Personally I only do silage clamps with 15’ panels
For fitting I would use heavy UC ( columns) You can then slide them inside the webs with no clamps etc

Definitely do not use 95mm panels for a silo. Mostly use 150mm over here but as Bob says 15' or 15'9" would be the longest recommended bay size.
We have done a few with 200mm thick panels, clamp machinery isn't getting any smaller.

we have built silage clamps with 20 foot bays using 6 inch panels to 3.6 m high the panels were specified with extra tension wires in to take the load and the calculations said that the clamp could not be rolled with a machine heavier than 10 tone the steelwork was 533 X 210 and the foundations took 8.3 m of concrete in each base

thankyou it is as I suspected this is going to cost me a sh!t tonne!

might try and find a way to persuade nrw to let me keep the earth banks and just concrete the floor.

Dig away the bottom part of the bank concrete in rsjs and drop in a 4' high panel, fill in behind the panel and reform the earth bank sloping back from the top of the panel. Cheaper option and easier to keep tidy than the earth bank going down to the floor.

Might be expensive but cheaper to do it once well than the situation we’re in. 15’ panels next time and bigger steels.

Why do a threequarter job?
Just form an earth bank at 45degrees and lay concrete slabs on it
No need for steel

I bought some 15’x5’ panels to lean onto my soil bank so I have a good edge to clean up against,never got round to fitting them yet,I’ve seen clamps use concrete sleepers before stood on their end,my back wall uses 10’x3’ concrete slats stood against a banking.

All bottom panels 200mm into concrete base. They’ve all cracked and steels not so upright as they were. Still used but need to be careful. Might in time need to form another wall away a bit and fill for bracing.
It can be a mistake to encapsulate the bottom of the panel fully in concrete as the second panel above will flex under load and if the bottom one is concreted in it will break the Tonge of on the second panel,The bottom panel needs a flexible joint formed at the bottom on the outside and then sealing

The existing clamp I use has earth banks with a 1500 panel slide into webbing but for me there is too much waste. What put’s you off shuttering price I’m guessing? Just starting too look into a new clamp here aswell so interesting reading, I was think of doing a long narrow one open at both ends so you can put multi cuts in, anyone done this?

We have a 45ft wide one, open at both ends. It began life 120ft long and now 255ft long. We left floor space for more steel uprights putting 3 bays on each time of expansion. 3m high sides, only 2m3 concrete per upright with one sheet of steel reinforcing round each to tie sides to the floor.

Works well we tend to fill one end and use from the other, but there is flexibility and we never have silage older than 18 months old.

That sounds about exactly what I was thinking 45 by 120-160 depending on capacity. Not had chance to work it out yet what sort of volume do you get in it?
