A single, central post in a roof truss in tension between the rafters and a tie beam (bottom chord), or 2) (U.S.) A short of the tie beam only supporting the rafters via struts. 3) (U.K.) A king post specifically carries a ridge beam otherwise is called a king strut. "King post" was formerly used to describe a crown post in the U. K., but no ...
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.
In classical architecture, an architrave (/ ˈ ɑːr k ɪ t r eɪ v /; from Italian architrave 'chief beam', also called an epistyle; [1] from Ancient Greek ἐπίστυλον (epistylon) 'on the column') is the lintel or beam, typically made of wood or stone, that rests on the capitals of columns. [2]
Camber beam – In building, a camber beam is a piece of timber cut archwise, and steel bent or rolled, with an obtuse angle in the middle, commonly used in platforms, as church leads, and other occasions where long and strong beams are required. The camber curve is ideally a parabola but practically a circle segment as even with modern ...
Other forms include stairs with winders that curve or bend at an acute angle, three flights of stairs that join at a landing to form a T-shape, and stairs with balconies and complex designs. A "mono string" staircase is a term used for a staircase with treads arranged along a single steel beam.
Historically a beam is a squared timber, but may also be made of metal, stone, or a combination of wood and metal [1] such as a flitch beam.Beams primarily carry vertical gravitational forces, but they are also used to carry horizontal loads such as those due to earthquake or wind, or in tension to resist rafter thrust or compression (collar beam).
Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter.
A structural support is a part of a building or structure that provides the necessary stiffness and strength in order to resist the internal forces (vertical forces of gravity and lateral forces due to wind and earthquakes) and guide them safely to the ground.
