Lifting a wooden grain floor

[eagleye]

well it took us nearly 3 months to do the job (relaying) but that included rebuilding the main air duct, building fan house, moving electrics, moving door, moving dividing wall, placing fans on top of duct and generator/heat exchanger, concrete outside door to bring up to new level etc as well as putting the boards down and more new boards 100'x 55'
but yes grain now comes off combine straight onto floor and I am not stuck working drier and transfering grain to this shed to store. 2-3 weeks a year saved plus wear and tear on telescopic, dust etc

we use it for w barley which usually comes in less than 20% and hopefully less than 18% which is then easy for the ventilated floor. tip 2 or 3 loads and then push up.

I really meant was it worth the hassle over buying a new one?

Only you can decide that,
Have you costed a new one, ?
think you may have to sit down when you read the quote !!

I dont do new, but how much are they?

 

[eagleye]

well for us 55x100 floor would have been approx £55k, add £15k for 2x 30kw fans with controls, 100ft main air duct £20k then all the other work we did anyway which we would still have had to do.
In all about half price.
The floor would need to be cheap or next to nothing. Took longer to dismantle the main air duct and side wall than the floor, only two of us and a forklift did the job. It was a warm job in up to 30c that year starting after 4,30am as the veg lifting squad in the field woke us up with the noise, working till about 9pm stayed at the farm ready for the next day - and repeat....

So a new floor is about £10/sq ft?
Are the bearers bolted to concrete?

 

[spanners and hammers]

new floor about 100 sq meter

Is it a challow?

 

[glasshouse]

My plan is to cut it along the middle of a plank, right down to concrete, into 30ft by 8ft sections , then glue back together

 

[chickens and wheat]

Bearers not bolted to floor.
Our older shed has a wooden tounge along top of each bearer top boards are shaped to fit
New shed has no tounge, boards just butt up.
New shed is easier to repair without this tounge.
New shed had boards that cover 3 rows old shed shorter board 2 rows

What ever you get make sure you can get new boards that match. different brands don't always mix with some reshaping efforts

 

[eagleye]

no idea what make it was, was not in sections like a challow advertise now.
Boards were hardwood possibly keruing, softwood bearers.
I would number the sections so you know where they go to match when you relay them.
Mice can have fun chewing thru bearers so that all needs checking before relaying

Linwood cut the bearers so they follow the concrete floor if not level, making the floor “weak” to move. Do other floor makers do the same?

 

[eagleye]

maybe Linwood then as the bearers were cut.

How do they cut the bearers?

 

[Rooney]

When they lay the floor they cut bearers before the top boards and mesh go on.
Helps leave bearers tight to floor but can leave air gap where cut. We put plywood over gap at side screwed on.

I cant follow that logic

 

[SilliamWhale]

@warksfarmer did a cheap one

If the concrete floor is not level that the wood floor is being layed on when the bearers (like floor joists in a house) as set down then they will have gaps under them where the floor dips. You cut the bearer to allow it to sit down on the concrete again.
Alternate is to plane the bearer on the high bits of floor. The top floor will not be flat if you cut the bearers but at least it will not flex or break as you drive over it.

I would have thought The floor would be better levelled
