| Summary: | The difficulty presented in the execution of "domical vault" or " quatre punts" timbrel vaults with diagonal brickwork is that of the marking out with cladding tiles in the layering of the first rows, when setting the pace of the construction and joins. The continuity of the joins is a sign of the good execution of the vault, resembling a translational surface made by the curved movement of the two parallel falsework systems. Experience in the execution of this complex procedure proves that faults and errors appear as the initial joins are lost and it is not possible to follow a specific geometry. A valid solution consists of approaching the vault as a toric surface, generated by the revolution of the generatrix arch taking the axis to be the vertical line perpendicular to the guide arch. The differences in proportion between the two surfaces are minimal, but with this second option the workman has more control over the marking out and execution, by using falsework systems that generate a repetitive sequence for the rows. |
