⭐ Core Definition: Scaffolding

Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other human-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects.

There are six main types of scaffolding used worldwide today. These are tube and coupler (fitting) components, prefabricated modular system scaffold components, H-frame / façade modular system scaffolds, suspended scaffolds, timber scaffolds and bamboo scaffolds (particularly in China, India and Hong Kong). Each type is made from several components which often include:

👉 Scaffolding in the context of Plank (wood)

A plank is timber that is flat, elongated, and rectangular with parallel faces that are higher and longer than wide. Used primarily in carpentry, planks are critical in the construction of ships, houses, bridges, and many other structures. Planks also serve as supports to form shelves and tables.

Usually made from timber, sawed so that the grain runs along the length, planks are usually more than 1+1⁄2 in (38 mm) thick, and are generally wider than 2+1⁄2 in (64 mm). Planks are often used as a work surface on elevated scaffolding, and need to be thick enough to provide strength without breaking when walked on. In the United States, planks can be any length and are generally a minimum of 2×8 (1+1⁄2 in × 7+1⁄4 in or 38 mm × 184 mm), but planks that are 2×10 (1+1⁄2 in × 9+1⁄4 in or 38 mm × 235 mm) and 2×12 (1+1⁄2 in × 11+1⁄4 in or 38 mm × 286 mm) are more commonly stocked by lumber retailers. Timber is categorized as a board if its width is less than 2+1⁄2 in (64 mm), and its thickness is less than 1+1⁄2 in (38 mm). In Germany, the national norm (DIN 68252) stipulates that the thickness of a plank (termed Bohle) must be 40 mm minimum.

Scaffolding in the context of Ledger lines

A ledger line or leger line is used in Western musical notation to notate pitches above or below the lines and spaces of the regular musical staff. A line slightly longer than the note head is drawn parallel to the staff, above or below, spaced at the same distance as the lines within the staff.

The origin of the word is uncertain, but may have been borrowed attributively from the term for a horizontal timber in a scaffolding, lying parallel to the face of the building and supporting the putlogs. There is no basis to support the often-found claim that the word originates from the French léger, meaning "light" or "slight" (OED 2005). The Oxford online dictionary describes the origin of the "leger" spelling as a "variant of ledger" that first appeared in the 19th century (Oxford Living Dictionary n.d.).

Scaffolding in the context of Solid hydrogen

Solid hydrogen is the solid state of the element hydrogen. At standard pressure, this is achieved by decreasing the temperature below hydrogen's melting point of 14.01 K (−259.14 °C; −434.45 °F). It was collected for the first time by James Dewar in 1899 and published with the title "Sur la solidification de l'hydrogène" (English: On the freezing of hydrogen) in the Annales de Chimie et de Physique, 7th series, vol. 18, Oct. 1899. Solid hydrogen has a density of 0.086 g/cm making it one of the lowest-density solids.
