Shape of the vault
Shape of the vault The shape of the vault has to meet three requirements.
In the first place you have to make sure that the construction does not
collapse. The shape of the vault has to sustain the thermal expansion and
contraction during heating and cooling down. After all the shape of the
vault determines if there is a good heat accumulation and if air
circulation is possible. To make a homogeneous and well done loaf of bread
you have to take the distance into account between the bread and the vault
that functions as heat source. Construction Crosswise, the vault has the
shape of an ellipse or basket-handle arch, where the stress is mainly
distributed vertically. Make sure that the inside of the vault is shaped
like a curve by setting the bricks close to each other. Lengthwise, the
ovular shape provides the best mechanical impedance. Thermal expansion
During stoking, the vault will be under stress due to thermal expansion. A
basket-handle arch allows to retain this expansion and, after...
