There are two kinds of trestle desk: as with trestle tables, some have trestles joined by one or more stretchers, and some have free-standing trestles. They can be dismantled, with the desk top removed from the trestles, for storage or transport.
A truss is an assembly of members such as beams, connected by nodes, that creates a rigid structure.
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.
A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support.
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.
A plate girder bridge is a bridge supported by two or more plate girders.
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a plank or beam such as the support structure for a trestle table. Each supporting frame is a bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation.
A lattice bridge is a form of truss bridge that uses many small, closely spaced diagonal elements forming a lattice. The lattice Truss Bridge was patented in 1820 by architect Ithiel Town.
In woodworking, a saw-horse or sawhorse 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.
Barmouth Bridge, or Barmouth Viaduct is a Grade II* listed single-track wooden railway viaduct across the estuary of the Afon Mawddach near Barmouth, Wales. It is 820 metres (900 yd) long and carries the Cambrian Line. It is the longest timber viaduct in Wales and one of the oldest in regular use in Britain.
In woodworking, a trestle table is a table consisting of two or three trestle supports, often linked by a stretcher, over which a board or tabletop is placed. In the Middle Ages, the trestle table was often little more than loose boards over trestle legs for ease of assembly and storage. This simple, collapsible style remained the most common Western form of table until the 16th century, when the basic trestle design gave way to stronger frame-based structures such as gateleg and refectory tables. Ease of assembly and storage has made it the ideal occasional table, and it remains a popular form of dining table, as those seated are not so inconvenienced as they might be with the more usual arrangement of a fixed leg at each corner.
The Cornwall Railway company constructed a railway line between Plymouth and Truro in the United Kingdom, opening in 1859, and extended it to Falmouth in 1863. The topography of Cornwall is such that the route, which is generally east–west, cuts across numerous deep river valleys that generally run north–south. At the time of construction of the line, money was in short supply due to the collapse in confidence following the railway mania, and the company sought ways of reducing expenditure.
The Landore viaduct is a railway viaduct over the Swansea valley and the River Tawe at Landore in south Wales. It provides a link between Swansea city center and the West Wales Line to the South Wales Main Line. The valley crossing provides a panoramic view of Landore, Kilvey Hill, the Liberty Stadium and the Swansea Enterprise Park.
The original Maroon Creek Bridge is a steel trestle along State Highway 82 at the western boundary of Aspen, Colorado, United States. It was designed by George S. Morison in 1888 for the Colorado Midland Railroad, one of the last viaducts in Colorado built for a standard gauge mountain railroad in the 19th century. Of the five steel bridges the Midland built, it is the only one still extant. Due to the later removal of most track and the rail depots, the bridge is the most visible remnant of rail service to Aspen. In 1985 it was listed on the National Register of Historic Places along with other highway bridges in the state, including the Sheely Bridge, also in Aspen.
Trestle or Trestles may refer to:
The Tulip Viaduct is a 2,295-foot (700 m) long railroad bridge in Greene County, Indiana, that spans Richland Creek between Solsberry and Tulip. According to Richard Simmons and Francis Haywood Parker, authors of Railroads of Indiana, it is "easily the state's most spectacular railroad bridge". The bridge was built in 1905 and 1906 by the Indianapolis Southern Railway and successor Indianapolis Southern Railroad, which became part of the Illinois Central Railroad in 1911. It is now part of the Indianapolis–Newton, Illinois, line of the Indiana Rail Road.
A stool is a raised seat commonly supported by three or four legs, but with neither armrests nor back a backrest, and typically built to accommodate one occupant. As some of the earliest forms of seat, stools are sometimes called backless chairs despite how some modern stools have backrests. Folding stools can be collapsed into a flat, compact form typically by rotating the seat in parallel with fold-up legs.
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.
The Murrumbidgee River railway bridge is a heritage-listed railway bridge across the Murrumbidgee River located on the Tumut railway line at Gundagai in the Cootamundra-Gundagai Regional Council local government area of New South Wales, Australia. It was built in 1903. It is also known as the Gundagai Rail Bridge over Murrumbidgee River and the Murrumbidgee River Railway Bridge. The property was added to the New South Wales State Heritage Register on 2 April 1999.
