The most common residential deck railing design is built on-site using pressure treated lumber, with the vertical balusters regularly spaced to meet building code. [1] Wood railing could be in different styles such as Victorian, Chippendale railing and others. [2] A popular alternative to wood railing is composite lumber and PVC railing. [3] [4 ...
Rail anchors, also called anticreepers, are spring steel clips that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration. Anchors may be attached and removed either by hand with hammers, or by an anchor machine.
Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"—a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...
Strut is normally made of sheet steel, with a zinc coating (), paint, epoxy, powder coat, or other finish.. Strut channel is also manufactured from stainless steel for use where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), from aluminium alloy when weight is an issue or from fiberglass for very corrosive environments.
Illustration of various examples of balusters, in A Handbook of Ornament, by Franz S. Meyer The term derives from the swelling form of the half-open flower of Punica granatum, in Italian balaustra A baluster ( / ˈ b æ l ə s t ər / ⓘ ) is an upright support, often a vertical moulded shaft, square, or lathe -turned form found in stairways ...
In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. In the case of railroad bridges, the railroad ties themselves may form the bridge deck, or the deck may support ballast on which the track is laid.
The catenary represents the profile of a simple suspension bridge or the cable of a suspended-deck suspension bridge on which its deck and hangers have negligible mass compared to its cable. The parabola represents the profile of the cable of a suspended-deck suspension bridge on which its cable and hangers have negligible mass compared to its ...
A handrail is a rail that is designed to be grasped by the hand so as to provide safety or support. [1] In Britain, handrails are referred to as banisters. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls, and to provide bodily support in bathrooms or similar areas.
