Trestle Support
In structural engineering, a trestle support (or simply trestle) is a structural element with rigid beams forming the equal sides of two parallel isosceles triangles, joined at their apices by a plank or beam. Sometimes additional rungs are stretched between the two beams. A pair of trestle legs can support one or several boards or planks, forming a trestle table or trestle desk. A network of trestle supports can serve as the framework for a trestle bridge, and a trestle of appropriate size to hold wood for sawing is known as a sawhorse. Trestle table A trestle table is a table with trestle legs. In shape and manufacture, it sometimes resembles variations of the antique field desk, which were used by officers close to the battlefield. Trestle legs come in two kinds: *Fixed trestle legs, where the angle between the legs is a fixed joint. *Folding trestle legs, where the angle is hinged, to make them more compact and portable. In the United States, a table or desk su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sawbuck Table
A sawbuck table or X-frame table is a type of trestle table having X-shaped supports at either end. It takes its name from the similarity of these X-shaped supports to sawbucks. In addition to the supports, a sawbuck table is distinguished by a sturdy central rail and key- tenon joints holding the supports and central rail together. Historically, sawbuck tables also often featured footrests running the length of the table. The sawbuck table originated in Pennsylvania in the early 18th century, and is a characteristic example of Pennsylvania Dutch vernacular design. The design is sufficiently sturdy that some sawbuck tables have remained in regular use for over 200 years. The earliest known modern picnic table was derived from the sawbuck table design, with the addition of attached benches on either side. Picnic table builders continued to experiment with sawbuck designs having separate benches until the invention of the modern A-frame picnic table in 1926. Sawbuck-style picnic ta ...

Sawhorse
In woodworking, a saw-horse or sawhorse (saw-buck, trestle, buck) is a trestle structure used to support a board or plank for sawing. A pair of sawhorses can support a plank, forming a scaffold. In certain circles, it is also known as a '' mule'' and a short sawhorse is known as a pony. The names come from the shape of the frame, which resembles a horse. A sawhorse may also be a rack for supporting logs for sawing, known in the US as a sawbuck. The sawhorse may be designed to fold for storage. A sawhorse with a wide top is particularly useful to support a board for sawing or as a field workbench, and is more useful as a single, but also more difficult to store. A sawhorse can also be used as the base for a portable work table by placing a sheet of plywood or even a door across two sawhorses. If the sawhorses are strong enough, the portable table can be used as a platform for tools like a table saw, although with caution if the top is not secured to the sawhorses. In boa ...

Stretcher (furniture)
A stretcher is a horizontal support element of a table, chair or other item of furniture; this structure is normally made of exposed wood and ties vertical elements of the piece together. There are numerous styles of the stretcher including circumferential, double and spindle design.''Genuine Antique Furniture'', Arthur de Bles, Published 1929, Thomas Y. Crowell This term is sometimes referred to as a stretcher beam. A very common pattern for chairs has each front leg connected to the back by the lateral stretchers, which in turn are connected by a medial stretcher. In the William and Mary period chi (from the Greek letter chi - Χ) stretchers were common, connecting the legs diagonally, frequently with a finial where the stretchers crossed.

Trestle Desk
There are two kinds of trestle desk: as with trestle tables, some have trestles joined by one or more stretchers (and sometimes to the desktop), and some have free-standing trestles. They can be dismantled, with the desk top removed from the trestles, for storage or transport. Antique trestle desk (linked trestles) The antique{{clarify, date=May 2021 trestle desk has linked trestles. It is usually very much like the writing table desk form, which offers a simple flat desktop surface with a few drawers underneath it. Unlike the writing table the trestle desk is supported by two legs instead of four, and the legs are designed to be dismantled easily in order to store or move the desk efficiently. More precisely, the two legs are two strong side supports which branch out in two feet each (for a total of four) at the bottom. These trestles are fastened together, and sometimes to the desktop, to make a rigid support. Some antique trestle desks are fitted with small cubbyholes and no ...

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments ( torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary ...

Bent (structural)
A bent in American English is a transverse rigid frame (or similar structures such as three-hinged arches). Historically, bents were a common way of making a timber frame; they are still often used for such, and are also seen in small steel-frame buildings, where the term portal frame is more commonly used. The term is also used for the cross-ways support structures in a trestle. In British English this assembly is called a "cross frame". The term ''bent'' is probably an archaic past tense of the verb ''to bind'', referring to the way the timbers of a bent are joined together. The Dutch word is ''bint'' (past participle ''gebint''), the West Frisian is , and the German is . Compare this with the term bend for a class of knots. Bents are the building blocks that define the overall shape and character of a structure. They do not have any sort of pre-defined configuration in the way that a Pratt truss does. Rather, bents are simply cross-sectional templates of structural members, i. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Control Channel
Flood control channels are large and empty basins which let water flow in and out (except during flooding) or dry channels that run below the street levels of some larger cities, so that if and when a flood occurs, the water will run into these channels, and eventually drain into a river or other body of water. Flood channels are sometimes built on the former courses of waterways as a way to reduce flooding. Levees Flood control channels are not to be confused with watercourses which are simply confined between levees. These structures may be made entirely of concrete, with concrete sides and an exposed bottom, with riprap sides and an exposed bottom, or completely unlined. They often contain grade control sills or weirs to prevent erosion and maintain a level streambed. Distribution By definition, flood control channels range from the size of a street gutter to a few hundred or even a few thousand feet wide in some rare cases. Flood control channels are found in most heavily dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
