Pizza Oven: Building the Inner Structure (the Dome)
5.Laying the Vermiculite Bricks
The vermiculite bricks supplied are 100mm x 100mm x 70mm high. There are sufficient bricks to cover the footprint completely.
Steps:
- First place a layer of ordinary brick mortar, about 20mm thick, where the bricks are going to be laid.
- Lay the bricks as shown bedded in the soft mortar.
- Make sure that the top surfaces of the bricks are reasonably level and in-plane. It is not important to keep the lines absolutely straight as you are not going to see them again.
After a day or two the mortar will be strong enough to proceed.
6. Installing the 4 x Floor Panels
- Locate the centre lines that you set out before.
- Loosely place the 4 x precast concrete floor panels on top of the bricks SMOOTH SIDE UP so that their joints line up with the centre lines. Mark and place aside.
- Place a thin layer of brick mortar on top of the vermiculite bricks.
- Level off with a straight edge.
- Replace the four panels, pressing them against each other edge-to-edge. Make sure they are bedded in and level on top. This is the final oven floor. It must be flat and level.
- Wait a while for the mortar to set before proceeding further.
7. Installing the Dome
As for the floor, the dome is supplied in quadrants. The quadrants are quite heavy. Get someone to help you lift and place them.
- First loosely place the panel with the door opening and make sure it faces the way you want it to. Mark and place aside.
- Place a 10mm thick x 50mm wide layer of soft brick mortar on the vermiculite bricks along the line of all the dome walls as shown.
- Now place first the panel with the door opening in. The apex should be in the centre above the cross on the floor.
- Then place the other three quadrants. Make sure that all panels fit together closely. The butt joints between panels must be as small as possible. Make sure proper bedding is achieved.
8.The last floor panel
The fifth floor panel can now be installed into the door opening.
- Again use some soft mortar and place it on the vermiculite bricks in the door opening.
- Level it off and lay the floor panel SMOOTH SIDE UP on it. Wriggle into position.
- Make sure the top of this panel is in-plane with the tops of the already installed oven floor.
