Ich würde meinen Brot- und Pizzaofen noch einmal genau gleich bauen
Der Ofen ist gut isoliert, er behält den Schnee auf der Kuppel auch wenn er innen über 200°C ist. Die Kuppel musste absolut wasserdicht sein, nicht in erster Linie wegen der Wärme und Isolation, sondern wegen dem Frost der dann alles zerreisst. Im Winter decke ich den Kamin mit Plastik ab und die Öffnung mit einer Schalungstafel. Dies ist jedoch schnell weg falls man Backen will.
Der Offen kann am Abend für Pizza gebraucht werden und hat dann am anderen Morgen immer noch über 200°C. Damit kann man Abend Pizza machen und am Morgen ein Brot in den Ofen schieben .
Heute nach fast 10 Jahren sieht er immer noch wie fast neu aus.
The location
A frost-proof substrate, lots of gravel and concrete
Stake out the mould
The foundation must be formworked.
Ready for concreting
The foundation is now being concreted.
Foundation smoothed
It can now harden. The electrical pipe is also inserted, you never know if you will need it.
Finished foundation
My first concreting job didn’t go badly at all.
Material for the base
The material for the oven base is ready.
Wall
The first row has to be very precise, because it is the template for all the others.
There are limestones everywhere
The work is progressing rapidly. The pool is ready to cool down.
Stove arch
The arch is bricked over a template. The electrical conduit goes with the wall on the left.
The plinth is finished
The top row is bricked with half bricks so that the base plate can be concreted on top.
The base plate
Here you can see the half bricks and the scaffolding for the formwork of the base plate.
Reinforcement of the slab
The formwork is ready. There is a film between the plinth and the formwork. There is an expansion joint on the side behind the film.
Ash chute
The recess for the ash chute opening. Everything must be constructed in such a way that it can be easily removed after the concrete has hardened.
Concreting the slab
The floating open slab can be cast. A bit of steel as the slab only rests on its side.
Curing the slab
Everything worked out. The tension belts were used to prevent the formwork from being pushed outward
Removing the formwork
Here you can see the expansion joint. The slab can expand by 2 cm without the plinth cracking.
Marking the position
Here I draw where the stove will stand.
Le Panyol stones
Le panyol 83 cm; the fireclay bricks from France are ready.
Oven plate insulation
Here I cut the base plate to size. There is a vermiculite slab under the firebricks.
Last row of plinths
Before I continue, I brick a row of half limestones all round. The last missing stone contains a socket, which is still missing.
Laying the plinth slab
On the concrete slab is first vermiculite (5cm), then ceramic mat (3mm), then quartz sand, then the refractory bricks
Temperature element
The temperature sensor is a thermocouple between the sand and fireclay. I filled the side cavity with loose vermiculite mixed with a little cement.
Levelling the stones
The stones are laid loosely. I check the height with the wooden slat.
Finished stove top
The base plate of the open is finished, I hope I haven’t made a mistake.
Filling the void
Finalise and fill everything.
Power socket
The power socket is now in place. I drilled the stone first and then bricked it in.
Erecting the dome
The construction of the stove can now begin. The ready-made stones from le Panyol were the ideal solution for me.
Levelling the stones
Progress is quick. The tenon in the centre should be a little higher, as it can slip in later.n.
Inspection
Looks good, doesn’t it? Everything inside is now covered so that the mortar inside does not soil everything.
Stove stones are supported
Everything is supported until all the bricks hold each other. It must be possible to remove all aids later from the inside through the oven opening.
Fix the bricks with wire
Everything is plastered with fireclay mortar. The wire secures everything until the mortar holds.
3 Thermoelemente
Links für in den Ofenraum. Oben für die Kuppelsteine. Rechts für den Boden.
Die Brennkammer ist fertig
Der Ofen ist verputzt und damit quasi fertig. Ein Zelt darüber damit der Regen den Ofen nicht durchnässt.
Fliesen der Ofenplatte
Die Ofenplatte wurde mit geneigten schwarzen Fliesen abgedeckt damit sich kein stehendes Wasser bildet.
Die Ofenöffnung
Ich wollte eine Front aus holänder Steine. Zwischen Ofen und Mauer fügte ich eine 2cm dicke Promoclad Keramikfaserplatte als Wärmeisolation ein.
Das erste Feuer
Sieht gut aus, Freude herscht!
Keramikfaservlies
So wie der Boden muss auch die Kuppel isoliert werden.
Rock wool insulation
After the fleece, a layer of rock wool was placed on top.
The owner at work
While it fires I insulated further.
Finished insulation
Everything I had came on top. The sensor is outside the insulation and is now under the plaster.
Aluminium as protection against frost.
Finally, I covered everything with aluminium foil and secured it with a rabbit wire mesh.
Dome ready for plastering.
It’s coming to an end. It’s about time, we started in spring and now it’s already late summer.
Schblone for the dome
The wire mesh is used to stabilise the plaster. The template for levelling the mould.
The first pizza
Baking pizza takes some practice.
Die Kuppel verputzen
Die Kuppel ist fest mit den Fliesen verbunden. Der Ofen innen kann sich dehnen und bewegen.
Silikonfuge beim Kamin
Die Kuppel ist fast fertig. zwischen Kamin und Kuppel. hatte ich eine hochtemp. Silikonfuge angebracht.
Liquid plastic.
I coated the stove with a liquid terrace coating. To make the stove hardy
The embers
The oven is glowing nicely; it is now over 400°C.
Temperaturanzeige
Die Temperaturanzeige misst drei Temperaturen: der Boden, die Kuppel und den Innenraum.
Die Umgebung
The oven is now just waiting for the first party opportunity.
The finished oven
The stove fits well into the picture.
Biscuit day
The oven retains its heat for a whole day of biscuit baking; in winter, of course.
The first Züpfe
Züpfen also turn out perfectly, as long as you know how to braid.
The fire
It is almost easier to light the fire if it burns from top to bottom.
