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]
A fishplate, splice bar or joint bar is a metal connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish, [1] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [2] The top and bottom faces taper inwards along their short dimensions to create an even ...
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 ...
The top members of a truss are known generically as the top chord, bottom members as the bottom chord, and the interior members as webs. In historic carpentry the top chords are often called rafters, and the bottom chord is often referred to as a tie beam. There are two main types of timber roof trusses: closed, in which the bottom chord is ...
The fibre counts have grown up to 144 per cable and can be installed in microducts of only 8 mm inner diameter. Bundles of microducts can be jetted over 1500 m or more. Microduct cables can even be jetted over 3.5 km in one single shot. More length without splice is reached by placing jetting equipment in tandem.
An early transistor socket and an integrated circuit socket are included for comparison. Tube sockets are electrical sockets into which vacuum tubes (electronic valves) can be plugged, holding them in place and providing terminals, which can be soldered into the circuit, for each of the pins. Sockets are designed to allow tubes to be inserted ...
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 protective porcelain ...
Splicebox. A splice box (also known as splice distributor) is a housing in which fiber optic cables begin or end. Fiber optics are fanned out in splice boxes that are situated at the end of fiber optic transmission paths. The main components of a splice box are the splice cassette that picks up the fibers and their reserves, and the front panel ...
