The wearing surface of a floor, usually laid over a subfloor

A base for a finish floor, consisting of boards, plywood, or other structural sheathing laid over and fixed to the floor joists

A framing member crossing and supporting the ends of joists, studs, or rafters, so as to transfer the weight to parallel joists, studs, or rafters

A beam, joist, or rafter supporting one end of a header at the edge of an opening in a floor or roof frame

A joist set on top of the sill and forming the perimeter of wood-framed floor. Also called header.

A relatively short beam, joist, or rafter supported by a wall at one end and by a header at the other. Also called stringer.

Bridging consisting of short boards fixed vertically between floor or roof joists

Bridging composed of diagonal braces set in pairs between floor or roof joists

Material, such as masonry or concrete, for filling the spaces between joists or beams in or on top of a masonry wall, stiffening the members, and providing increased fire resistance

An opening in the vertical face of a structural member to receive a beam

An angular cut at the end of a joist or beam where it enters a masonry wall, allowing the member to fall without damaging the wall if it burns through somewhere along it length

Self-supporting units of wood, metal, or concrete capable of spanning beams, joists, rafters, or purlins and serving as a base for flooring or roofing

A steel pin welded to the top flange of a steel beam or girder and embedded in a concrete slab so as to cause the beam and the concrete to act as a structural unit

Metal decking serving as permanent formwork for a reinforced concrete slab until the slab can support itself

Metal decking containing glass fiber between the perforated webs of ribbed decking or in the perforated cells of cellular decking, used as a sound-absorbing ceiling

Metal decking serving as permanent formwork and tensile reinforcement for a concrete slab bonded to it by a deformed or dovetail rib pattern

Sheet steel strengthened for use as floor or roof decking by cold-rolling a series of ribs or flutes into it, and usually galvanized for corrosion resistance

Metal decking manufactured by welding a corrugated steel sheet to a flat steel sheet, forming a series of raceways for electrical wires and cables

A system of removable and interchangeable floor panels supported on adjustable pedestals or stringers to allow free access to the space beneath

Material used for the wearing surface of a floor, such as hardwood, terrazzo, or floor tile

Finish flooring in the form of wood strips, planks, or blocks

Flooring composed of long, narrow wood strips, usually side- and end-matched

Flooring composed of boards wider than strip flooring, usually side- and end-matched

Flooring composed of square units preassembled at the mill and usually installed with mastic over a wood subfloor or concrete slab

Long-wearing flooring composed of solid wood blocks set in adhesive with their grain oriented vertically

Laminated wood flooring made by pressure-gluing cross piles for greater dimensional stability and having a wear layer of solid, often prefinished hardwood

A flooring block made by joining short lengths of strip flooring edgewise, usually tongued on two adjoining sides and grooved on the other two to ensure proper alignment in setting

A flooring block made by bonding three or more wood veneers with a moisture-resistant adhesive, usually tongued on two opposing sides and grooved on the other two to ensure proper alignment in setting

A flooring block made by assembling narrow slats or fingers of hardwood into larger units

A floor composed of short strips or blocks of wood forming a pattern, sometimes with inlays of other woods or other materials

Mosaic work of wood used for floors and wainscoting

Of or pertaining to a wood or stone piece having a back face hollowed out so that it can fit more tightly against an irregular surface
