Re: My 40" Inch pizza oven in Florida

Looking good in. Still love your entry wide and very well built. Will look at your detail more when I get to this point. A way off at the moment.

Thanks,
Any questions let me know. Although I think there is a lot more experienced help here on the forum. I'll try to help ya anyway I can.

Hope your boy has a great bday.


Ok Guys,
There seams to be some differing opinions going around........One reason I try to error on the side of caution.

Didn't think that was necessary for a hemispheric arch.
Brickie?

Unless the material the arch is made of is strong enough in tension you need to. Even a hemispherical arch still has force vectors not in line with the legs.

I'm incorporating a four inch rebar reinforced block buttressing wall on each side of my hemispherical arch. At the base of the arch a 2 1\2" void separation between block buttress wall, this will get larger as the arch curves. I plan to fill this with a vermiculite insulating concrete.

I did not feel comfortable leaving my arch un buttressed.
I think I should be able to sufficiently buttress my arch with the proper ratio mixed insulating concrete. I was thinking 6:1 vermiculite to Portland cement.

What are everones thoughts and suggestions?

Read this page, then the whole site.

If you have to buttress a semi circle arch then surely you would have to buttress a semi circle dome too?

That page and site has a lot of interesting and helpful information. From my understanding of their description on that page they distinguish between a ?circular dome? and an individual arch by describing the additional circular force acting within the dome structure. While the dome cross section is essentially a semicircular arch, absent this circular force the stand alone arch is seemingly less stable and as Tscarborough mentioned above it should have some buttressing.

I buttressed my entry arch somewhat because I figured it needed it but more so because of my rudimentary masonry skills and fear that it could be weak because I didn't know what I was doing.

John,
I agree very good article good info, a little above my pay grade and my rudimentary skills also. I'll error on the side of safety. Hope to pour some insulating concrete around the arch today.

KB,

That sure is looking nice. How far from the real kitchen is the oven?

And remember if you turn out a marginal pie..... you might get a dunk in the pool from the recipients for not being a pizza master.

Not necessarily....there are infinite variables which factor into whether buttressing is needed or not.

One thing for sure, it won't hurt anything if a buttress is included in the build..good insurance.

Re: My 40" Inch pizza oven in Florida

The fact that you loaded the arch and removed the centering without a hinge failure proves you have enough thickness in your arch without adding a buttress. For your span of 20"....3"-3.5" thickness on your arch is sufficient.


That said, you won't go wrong if...

...I'll error on the side of safety.....

There is wisdom in caution.

Thanks Chip,

The kitchen is across the pool in the house. Hopefully I can master the pie soon and avoid the dunk, I'm sure I will with everyone expert advice.

Thanks Texman,
Coming from a master builder like yourself,that means a lot.

I like your outer decorative arch I hope to do something similar. I noticed that there is no over lap of the outer vent arch and you have no smoke stains outside of the oven. I was considering having a over lap to avoid stains. The draw of the chimney must be the key.

Hope to put a fire in her soon.

Thanks Stonecutter,
I really appreciated all your advice and wisdom.


Ok Guys,

I poured the insulating/buttressing concrete yesterday. I think I should be able to remove form boards today. How soon can I put a fire in her. I'm getting anxious.

I would give the portland in the vcrete at least 7 days to cure before firing.

Bummer ..............................its going to be a long wait

[Tscarborough]

Re: My 40" Inch pizza oven in Florida

I lit the first fire in mine about 15 minutes after I pulled the arch form out. Just build the heat slowly and you are good.

No one get there panties in a wad, but couldn't wait........... It's official, first fire......although just a draw test on the flu, a wad of paper........... I think I will let her rest and cure while I work on insulating and the enclosure.....................
