The gusset plate is usually painted to match nearby steel and fixtures and to give it an extra layer of protection. [2] Occasionally gusset plates are made from copper or aluminum, but only with small structures that do not require much support. The copper and aluminum gusset plates also provide a more attractive finish for exposed structures. [2]
Truss plates are light gauge metal plates used to connect prefabricated light frame wood trusses. They are produced by punching light gauge galvanized steel to create teeth on one side. The teeth are embedded in and hold the wooden frame components to the plate and each other. Nail plates are used to connect timber of the same thickness in the ...
This is an example of a "double roof" with principal rafters and common rafters. A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. Trusses usually occur at regular intervals, linked by longitudinal timbers such as purlins. The space between each truss is known ...
Splice or butt connectors (primarily insulation displacement connectors) that permanently join two lengths of wire or cable. In computing, electrical connectors are considered a physical interface and constitute part of the physical layer in the OSI model of networking.
Earthing systems. v. t. e. Knob-and-tube wiring (sometimes abbreviated K&T) is an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s. [1][2] It consisted of single-insulated copper conductors run within wall or ceiling cavities, passing through joist and stud drill-holes via ...
A Howe truss is a truss bridge consisting of chords, verticals, and diagonals whose vertical members are in tension and whose diagonal members are in compression. The Howe truss was invented by William Howe in 1840, and was widely used as a bridge in the mid to late 1800s.
Gusset plates, usually triangular, are often used to join metal plates and can be seen in many metal framed constructions. Expanding folders or accordion folders also employ gussets to allow for expansion when containing more than just a few sheets of paper. The gusset is also a charge in heraldry, as is the gyron (an Old French word for gusset).
A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self-contained assembly (usually the size of a large carpenter's nail). [ 1] The fibers are not permanently joined, just precisely held together so that light can pass from one to another. This impermanence is an important advantage over ...
