Shield arch
A shield arch is the line or inner edge that occurs when a reveal of the vault cap of a barrel vault or cross vault meets the shield or front wall, or an arch adjacent to the wall .
designation
The vertical, semicircular surfaces, which, like a gable wall, form the end of barrel vaults , are called shields . Accordingly, a fitting at the sign will bow as a sign arc called. Shield arch ribs, wall ribs or wall straps are profiled shield arches protruding in front of the vault reveal and the shield wall.
use
Often one encounters shield arches in the ribbed vaults and groin vaults of medieval churches above the windows of the Obergade zone , but also above the windows of the aisles.
With a cross vault , from two penetrating barrel vaults, four shields are created, i.e. also four shield arches. Church naves often consist of several yokes , each with a cross vault. In this case, the vaulted arches on the side walls, in the longitudinal direction of the nave, are called dividing arches , while the yoke- dividing arches across the direction of the nave are called belt arches .
Notre-Dame de La Souterraine , ribbed vault, 2 divider arches and 2 belt arches.
Ste-Trinité d'Anzy-le-Duc , central nave, groin vault with shield arches and belt arches
Sts-Pierre et Paul de Montceaux-l'Etoile , barrel vault with a shield arch
