Fall on panelled clamp

[SJM]

Looking at building a silage clamp using rsj’s and panels on the inside face so no lip from the rsj. 12x50m long with a 1% fall so 0.5m of fall back to front. What’s the best way to put the panels on a slope? Thought about setting them in to the concrete slab to stop effluent but then will lose 0.5m of panel by the back of the clamp. Thanks

Set up your steel then weld a foot on each at the correct height and slope.

When I did my clamp I put the rsj's slightly off plumb (x degrees off plumb depending on fall and length required) an put the panels onto weld on plates at the correct height. Then when floor was concreted let the concrete flood under the panel and up about inch or so to seal it.

Then pour the floor afterwards say, 50mm up the panel?

Sounds great. Have you any photos? Pm if you’d prefer

On the pit we have done we have just stepped the panels each bay so we welded tabs on the post to sit the panel on one lower and on higher ..

Yes, set a shutter up outside to retain the concrete, the concrete will grip the panel sealing it rather than leaving a gap as it cures. Also adds strength to the panel. You could form a gutter outside to catch any effluent, have seen this done and it is effective.

Here is a few pictures, my clamp is only 12m x 24m on the short side with a fall of about 750mm back to front.

Dont put the panel in the concrete. They need to flex. I know of someone that has a 5 year old pit and the bottom panels have cracked. Because he has put concrete round the outside edge. You can get the panel manufactures to do the panel on the run. Jones Brothers can do it.

How are does panels held to the girders? Is there not a lot of stress behind the panels when backfilled?

Also, why didn’t you go two panels high?

Panels held on by normal clamps to steels but welded them as well incase they spun, was going to put a plate over the top and down but didn't bother. There is solid rock all around so only backfilled about 18 inches so should be ok. Only wanted to make an edge between floor and wall. Panels are 150mm double load bearing.

surely a shuttered clamp like this would be better

good point i have seen this happen,You need a compressible filler on the outside and need to stop the concrete griping the tongue at the bottom of first panel,Panel people can add extra tension wires to the outer face of bottom panels

That looks brilliant. Thanks. What size steels have you used?

Very nice. Probably is better but no tax breaks unlike panels.

They are 10" X 6"" I think,got them from local shed maker as offcuts for free hence why some are painted and some are galv.

Sounds perfect!

Should have got them all galvanised
