groined vault
Definition
Noun: A groined vault is an architectural structure formed by the intersection at right angles of two barrel vaults of equal size. This intersection creates a network of arched ribs, or groins, along the lines where the vaults meet.
Usage
The term is used specifically in architecture and architectural history to describe a type of ceiling or roof structure. * The nave of the cathedral is covered by a magnificent groined vault. * Groined vaults were a significant development in Romanesque and Gothic architecture, allowing for better support and larger interior spaces.
Advanced Usage
- Technical Description: In technical descriptions, a groined vault is analyzed by its constituent parts: the two perpendicular barrel vaults and the groin arches (or arrises) formed at their intersection. The weight is channeled down these groins to supporting piers or columns.
- Historical Context: The development of the groined vault was a precursor to the more complex rib vault, which used distinct ribs to define the groins before the vault's web (infill) was constructed.
