A tie rod or tie bar is a slender structural unit used as a tie and capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle.
A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings. In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing.
Powwow, also called Brauche, Brauchau, or Braucherei in the Pennsylvania Dutch language, is a vernacular system of North American traditional medicine and folk magic originating in the culture of the Pennsylvania Dutch. Blending aspects of folk religion with healing charms, "powwowing" includes a wide range of healing rituals used primarily for treating ailments in humans and livestock, as well as securing physical and spiritual protection, and good luck in everyday affairs. Although the word "powwow" is Native American, these ritual traditions are of European origin and were brought to colonial Pennsylvania in the transatlantic migrations of German-speaking people from Central Europe in the seventeenth and eighteenth centuries. A practitioner is sometimes referred to as a "Powwower" or Braucher, but terminology varies by region. These folk traditions continue to the present day in both rural and urban settings, and have spread across North America.
A barn raising, also historically called a raising bee or rearing in the U.K., is a collective action of a community, in which a barn for one of the members is built or rebuilt collectively by members of the community. Barn raising was particularly common in 18th- and 19th-century rural North America. A barn was a necessary structure for any farmer, for example for storage of cereals and hay and keeping of animals. Yet a barn was also a large and costly structure, the assembly of which required more labor than a typical family could provide. Barn raising addressed the need by enlisting members of the community, unpaid, to assist in the building of their neighbors' barns. Because each member could ask others for help, reciprocation could eventually reasonably be presumed for each participant if the need were to arise.
Timber framing and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany, where timber-framed houses are spread all over the country.
Jettying is a building technique used in medieval timber-frame buildings in which an upper floor projects beyond the dimensions of the floor below. This has the advantage of increasing the available space in the building without obstructing the street. Jettied floors are also termed jetties. In the U.S., the most common surviving colonial version of this is the garrison house. Most jetties are external, but some early medieval houses were built with internal jetties.
A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts, radio masts, wind turbines, utility poles, and tents. A thin vertical mast supported by guy wires is called a guyed mast. Structures that support antennas are frequently of a lattice construction and are called "towers". One end of the guy is attached to the structure, and the other is anchored to the ground at some distance from the mast or tower base. The tension in the diagonal guy-wire, combined with the compression and buckling strength of the structure, allows the structure to withstand lateral loads such as wind or the weight of cantilevered structures. They are installed radially, usually at equal angles about the structure, in trios and quads. As the tower leans a bit due to the wind force, the increased guy tension is resolved into a compression force in the tower or mast and a lateral force that resists the wind load. For example, antenna masts are often held up by three guy-wires at 120° angles. Structures with predictable lateral loads, such as electrical utility poles, may require only a single guy-wire to offset the lateral pull of the electrical wires, at a spot where the wires change direction.
Hex signs are a form of Pennsylvania Dutch folk art, related to fraktur, found in the Fancy Dutch tradition in Pennsylvania Dutch Country. Barn paintings, usually in the form of "stars in circles", began to appear on the landscape in the early 19th century and became widespread decades later when commercial ready-mixed paint became readily available. By the 1950s commercialized hex signs, aimed at the tourist market, became popular and these often include stars, compass roses, stylized birds known as distelfinks, hearts, tulips, or a tree of life. Two schools of thought exist on the meaning of hex signs. One school ascribes a talismanic nature to the signs; the other sees them as purely decorative. Both schools recognize that there are sometimes superstitions associated with certain hex sign themes and neither ascribes strong magical power to them. The Amish do not use hex signs.
A purlin is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin.
In art and iconography, a motif is an element of an image. Motifs can occur both in figurative and narrative art, and in ornament and geometrical art. A motif may be repeated in a pattern or design, often many times, or may just occur once in a work.
A five-pointed star (☆), geometrically an equilateral concave decagon, is a common ideogram in modern culture. Comparatively rare in classical heraldry, it was notably introduced for the flag of the United States in the Flag Act of 1777 and since has become widely used in flags.
Anchor bolts are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts, steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.
Dutch barn is the name given to markedly different types of barns in the United States and Canada, and in the United Kingdom. In the United States, Dutch barns represent the oldest and rarest types of barns. There are relatively few—probably fewer than 600—of these barns still intact. Common features of these barns include a core structure composed of a steep gabled roof, supported by purlin plates and anchor beam posts, the floor and stone piers below. Little of the weight is supported by the curtain wall, which could be removed without affecting the stability of the structure. Large beams of pine or oak bridge the center aisle for animals to provide room for threshing. Entry was through paired doors on the gable ends with a pent roof over them, and smaller animal doors at the corners of the same elevations. The Dutch Barn has a square profile, unlike the more rectangular English or German barns. In the United Kingdom a structure called a Dutch barn is a relatively recent agricultural development meant specifically for hay and straw storage; most examples were built from the 19th century. British Dutch barns represent a type of pole barn in common use today. Design styles range from fixed roof to adjustable roof; some Dutch barns have honeycombed brick walls, which provide ventilation and are decorative as well. Still other British Dutch barns may be found with no walls at all, much like American pole barns.
An anchor plate, floor plate or wall washer is a large plate or washer connected to a tie rod or bolt. Anchor plates are used on exterior walls of masonry buildings, for structural reinforcement against lateral bowing. Anchor plates are made of cast iron, sometimes wrought iron or steel, and are often made in a decorative style.
The Parker Training Academy Dutch Barn is located at that institution on Turkey Hill Road in the town of Red Hook, New York, United States. It is a wooden structure built in two stages between 1790 and 1810. In 2007 it was listed on the National Register of Historic Places.
The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components. A definition is "the displacement of building elements due to the expansion of iron and steel products as the metal rusts and becomes iron oxide". Corrosion of other metals such as aluminum can also cause oxide jacking.
American historic carpentry is the historic methods with which wooden buildings were built in what is now the United States since European settlement. A number of methods were used to form the wooden walls and the types of structural carpentry are often defined by the wall, floor, and roof construction such as log, timber framed, balloon framed, or stacked plank. Some types of historic houses are called plank houses but plank house has several meanings which are discussed below. Roofs were almost always framed with wood, sometimes with timber roof trusses. Stone and brick buildings also have some wood framing for floors, interior walls and roofs.
Primitive decorating is a style of decorating using primitive folk art style that is characteristic of a historic or early Americana time period, typically using elements with muted colors and a rough and simple look to them. Decorating in the primitive style can incorporate either true antiques or contemporary folk art. Contemporary primitive folk art is designed to have an old or antique look but created using new materials.
