grain store concrete panels

[agcon1]

converting hay barn to a grain store, floor will be laser levelled and power floated, question is, which is best....set panels up so they sit in the concrete, or lay floor and then sit them on top?.... pros and cons for each please

sit in concrete, stops water coming in.
on top of floor the water can get under panels
there was a thread on this before

If the panels are under the concrete it also stops you catching the edge of the bucket under the panel

We did a Dutch barn in the summer, welded lugs to the stanchions for the panels to sit on, set the first run of panels on the lugs then concreted the floor. We set the panels level from front to back, so the bottom of them was 4” below finished level at the back of the shed and 1” below finished level at the front, then we gave the cement a 3” run from front to back (60 foot shed).

It gave the panels a good hold of the ground, a good seal for water as has been said already and most important I think is that it gives a nice edge for the bucket to run against when loading grain out of it...

I'm building a grain shed in the new year and was thinking about using panels, I wonder how you close up the space when the side sheeting comes down to meet the panel if the panels are kept internally against the stanchion? I would want to keep small birds out of the shed. Is it a real hassle fitting the panels between or inside stanchions instead? Do the panels always have to be fitted at the same time as the stanchions going in when putting them in the H beam?

Mine are inside the stanchion, it makes the wall cladding simple, you just sheet down 12" below the top of the panels... nothing to fill in, and you get a shed 2 foot wider inside.

The hard bit is getting them in, they have to be cut accurately so you can put one end in and just get the other in before centralising, if your stantions are loose on the bolts it helps, a sheet of ply wood in the right place as they swing in also helps, you do end up with a nicer looking shed though.

agcon1, I've a lot of nice examples from company Urbanist Architecture. Converting houses into flats article, when I saw it first time, seemed not so realistic, but after some real examples, I've seen in Croydon, and after getting some additional information about this firm, I've done it for myself as well.

how you get it dead flat with nothing to tamp off, i know you can get it close if you wet it up and go though it just wondered if you had any top tips.

Get the cement nice and wet for a start, then lead off the bulker with a loadall bucket so you can dump the concrete to exactly where you need it rather than the driver putting out a big slosh every few meters.
One person works a laser level staff, and a couple of men with rakes levelling as required. Then run from front to pack with a 6 meter power screed, leave it for a few hours then power float a few times. Far easier than buggering about with shuttering etc like we used to do!

My contractors order it wet (very important not to add water) and one is in charge of the chute instructing driver when to move, another rakes according to the man with laser level, its all looks very easy and un-rushed, remember to tie up the powerfloat at the back of the building to make a start as it goes off.

i have to say used loadall last time and just added last bit of shutter at front or shed at the end, as you say i got the concrete where it was needed and made the job much easier load less moving it about with rakes.

i cold reach over a large section with wood to check it was ok and borrowed a home made tamp tool (5 ft plasters rake with handle welded on) which we walked though with working the concrete, this got air out and i have to sat make it dam flat.

Floated it off with an 8ft long reach float which worlked well im not flash enough for a power float.

ive got another 30ft square to do in shed but there is no where to tamp from but im less fussy about this bit being perfect as its just for machinery storage.

how long did you leave it before going on with vibrating tamp?

You dont need the tamp with the correct mix, just easyfloats, and to be really smooth hire a powerfloat.

spill flashing

 

[GrantMo]

Every time we emptied a load we pulled the power screed over it. They float over it no problem, and it wasn’t expensive to hire from GAP for the day.
We then left it about 3 hours before going on with the polisher, that was a hot day in the summer though it would need a bit longer at this time of year. Do the polishing with slippers or crocs to save making imprints on the surface which you then need to polish out!

Ideally the panels want to be smooth internally so fixing them against the stanchion is best

Along the top edge they will fit a spill flashing

Got a hay barn with 20 ft bays with 6 inch panels . Two high . Thinking of concreting this for grain will the panels be strong enough ?
thanks

 

[quattro]

Panel’s will b ok more depends on legs

 

[RAF]

10 year old shed .12 inch legs but bolted in . Wonder weather to put rsj in middle and then be able go 3 high .

10 year old shed .12 inch legs but bolted in . Wonder weather to put rsj in middle and then be able go 3 high .

Bolted below ground then concreted in ?, 12 “ steels sound ok but what’s the span and height

 

[RAF]

Sorry 10 inch by 6 inch steels bolted in with around 12 - 18 inch concrete up them , shed is 16 ft high 45 ft wide . Will 3 panels high hold up on grain . Didn’t really want have put a rsj in middle if can help it .
thanks
