Concrete panel fitting

[Jameshenry]

Hopefully having a new shed put up soon, 15ft bays with 1.5mtr high panels all around, i like the idea of having lugs welded on the posts for panels to sit on, but my shed builder reckons to sit them on engineering blocks, thoughts ?

Lugs

 

[biggmw]

Yep lugs.... Best way I have found.

 

[BobGreen]

Landing plates on posts. Only way

Have seen both done regularly, but prefer lugs as long as they are welded on at the same height all the way round.

Bolt on lugs is best option, then if they have levels issues, they can just re-make a bolt on lug

Go round with a laser level and weld lugs on at the same height.

Go round with a laser level and weld lugs on at the same height.

Some shed men weld them on when they are fabricating the posts but then don't put the posts up level.

Would share @BobGreen view as best practice.

 

[Steevo]

Lugs every time. If the shed builder gets things right on the steelwork, everything else just slots together without an issue.

 

[MrA.G.]

We went with lugs. In hindsight we should have turned the angle the other way to provide more bearing for the panels.

I'd like to see the lug out past the web of the post. Normally tell customers to run the concrete out through below the panel a few inches when pouring the floor to give a good seal at the ground and provide good support around the post/ lugs.

All ours have been like this

For grain are you all setting the bottom height of the panel to the bottom of the concrete floor ?

 

[designanddetail]

Usually set the bottom of the panel 50mm below the finished concrete level.

Thats how I do all of mine but sometimes use 3x3 angle instead of abit of beam depends what I have really.

 

[Hesston4860s]

Usually set the bottom of the panel 50mm below the finished concrete level.

We do 50mm below FFL inside and only concrete up 25/30mm outside to stop capillary action.

Do they just constantly give problems if sealed down to a flat slab?

I know of someone that just sat them on top of the slab and used a gazillio tubes of mastic to seal them, they all leak to this day even after he went round with another gazillion tubes of mastic ?

I thought as much.
I'm debating setting road forms up in the pannels position to concrete to, how do you keep exact concrete height with pannels in first? Use laser level plenty? Or get one of these firms in with level bar thingy? Are they dear?
