Two barrel vaults or curving ceilings intersect to produce a groin vault. A groin is the curving junction of two vaults. Vault junctions can be inside or outside groins; both employ the identical template-creation technique. Where do groin vaults come from? Groin vaults were originally used in churches where there was not enough space for flat ceilings. These unusual shapes are still found today in public buildings and museums around the world.
Groin vaults are commonly found in European architecture and date back as early as the 11th century. They are also known as triapsidal vaults because they have three equal arms branching off the central hub of the vault. The three arms form an equilateral triangle with each side measuring about 18 feet. The apex of the triangle is about 30 feet above the floor. In order to fit under these ceilings, you would need to be at least 1.6m (5'3") tall!
They are made out of steel or wood and cover the entire room except for one small area near the door. There, the architect creates a hole through which to view the sky. Sometimes this opening is covered by a dome or lantern.
These beautiful ceilings deserve to be seen up close. That's why we put telescopes at our rooftop observatory so that you can see all their details without having to climb up hundreds of stairs!
A groin vault or groined vault (also known as a double barrel vault or cross vault) is formed by the right-angle junction of two barrel vaults. The margin between the intersecting vaults is referred to as the "groin." Groin vault arches are sometimes pointed rather than circular. They may be simple or have various kinds of molding and carving around their openings.
The word "vault" here does not mean a large enclosed space but rather just a small room with no more than a four-foot roof height. Vantage points such as windows and doors are called openings in the roof. The term "ceiling" refers to the flat surface covered by boards, plastic, or other material. This term is used interchangeably with "roof" when talking about buildings or vehicles with roofs.
In architecture, a groin vault is a type of vault in which the ribs that support the ribbed vault meet at a right angle. Thus, there are two sets of ribs, one on each side of the centerline, with the outer ends of each set meeting at right angles to form a single ridge pole for the vault.
A vault formed by the right-angle junction of two barrel (tunnel) vaults. They usually have flat or slightly raised panels, but may be round with elliptical openings.
The word "vault" comes from Latin via French, meaning "a cover or lid over something." In architecture, a vault is a roof construction that covers a room or space below. The term can also refer to a large dome-shaped structure used for covering an area such as a court or market place.
Barrel vaults were commonly used in Europe from the 11th through the 14th centuries. They consist of a series of intersecting ribs or barrels that form the shape of the vault. The number of barrels required varies according to the size of the vault being constructed. For example, a four-barreled vault would require only eight vertical supports for its construction.
Groin vaults were common in England from about 1350 to 1550. They share many similarities to barrel vaults but instead of using horizontal members to connect the ribs together, they use vertical posts called "groins". Each post ends in a sharp point which fits into a socket cut out of the next post down.
Grain vaults (also known as groin vaults) A vault formed by the junction of two barrel-vaults that cross at a right angle. Its thrusts are centered along the groins or arrises, finally reaching the four corners. The word comes from Latin grainium, "a kernel of corn", and originally meant "the shell of a corn kernel". In architecture, the term refers to a type of vault in which the ribs forming the roof do not run continuously round the building but instead intersect at right angles, forming a grid pattern. There are two types of grain vault: one with flat surfaces (as on most churches built before the 13th century), the other with ribbed surfaces.
The plural form of this word is grains.
Grain vaults are found mostly in medieval churches. They were used instead of transverse vaults because they required less structural support than a transverse vault. Also, grain vaults are more efficient use of space than transverse vaults since there are no diagonal ties between vaults and so there can be more open area inside the structure. Finally, since grain vaults do not have continuous supporting walls all the way around them, they offer more room inside the church for storage or other purposes.
In conclusion, the plural form of grain vault is grains.
What exactly is a groin vault? A groin vault is made up of two barrel vaults of the same diameter that cross or intersect. The distance between the centers of their openings is called the height of the vault. A horizontal round opening in the center of the vault lets light into it.
The word "vault" comes from the Latin vacca, meaning cow. Thus, a groin vault is like a pair of cow horns attached to the top of a wall with a hole in the middle. The term "cowhouse roof" is also used for this type of construction.
Groin vaults were commonly used in medieval church buildings as transverse arches over naves and other large rooms. They are still found in many barns and warehouses built before the advent of steel framing techniques. They are also used as roof supports on industrial buildings, factories, storage tanks, and oil wells. They require very little material to build them, which makes them economical despite their appearance. Their weight tends to be distributed evenly, so they do not cause walls to collapse.
In architecture, a groin vault is a kind of vault in which the ribs rise at an angle from the base to the apex. They are formed by connecting together several pairs of cylindrical barrels with circular holes cut through them.
A vault is a structural element in building construction that consists of an arrangement of arches, commonly forming a ceiling or roof. When two barrel vaults crossed at right angles, they produced a groin vault, which, when repeated in sequence, could span rectangular expanses of infinite length. The word "vault" comes from the Latin verb vehere, "to bear up." In architecture, a vault is a domed structure, usually made of concrete or steel, used to cover a room or space below it. They are used for various purposes including shelter, storage, and decoration.
The word "vault" is used today to describe several different types of structures: one-piece shell vaults over rooms; segmental-vault buildings in which walls and roofs are separated by vertical divisions called joists or beams; and multiunit vaults such as parking garages where floors are supported by columns placed on end. Shell vaults were originally used primarily as rainwater collectors but also as shelters for food and tools or weapons. Today they are used mainly for decoration and protection against the elements. Shell vaults have been extensively used by builders throughout history because of their ability to collect water and release it slowly through small holes provided for ventilation. These shells can be made of wood, metal, or cement and range in size from small pools for garden use to large structures for industrial applications.
