Support area upon which something rests, such as the point on bearing walls where the weight of the floor joist or roof rafter bears.

Curvature built into a beam or truss to compensate for loads that will be encountered when in place and load is applied. The crown is placed upward. Insufficient camber results in unwanted deflection when the member is loaded.

Contraction Joint

aka: control joint - contraction joints are joints either sawn or tooled into a concrete surface to create a decreased section at which the concrete will most likely crack as it shrinks. The intent of contraction joints is to "control" the crack locations and prevent random cracking of the concrete.

A roof that rises by inclined planes from all four sides of a building.

A platform between flights of stairs or at the termination of a flight of stairs.

A post to which the end of a stair railing or balustrade is fastened. Also, any post to which a railing or balustrade is fastened.

An extension of a rafter beyond the wall line. Usually a smaller member nailed to a larger rafter to form a cornice or roof overhang.

The replacement of excavated earth into a trench around and against a basement foundation.

A mineral closely related to mica, with the faculty of expanding on heating to form lightweight material with insulation quality. Used as bulk insulation and also as aggregate in insulating and acoustical plaster and in insulating concrete floors.

In architecture, a mezzanine or entresol is an intermediate floor between main floors of a building, and therefore typically not counted among the overall floors of a building. Often, a mezzanine is low-ceilinged and projects in the form of a balcony. The term is also used for the lowest balcony in a theatre, or for the first few rows of seats in that balcony.

The side and head lining of a doorway, window, or other opening.

Wood or metal plate riveted, bolted, glued or pressed (wood trusses) over joints to transfer stresses between connected members.

Shoring and forms that hold concrete in the proper shape as it hardens.

An opening in a sloping roof, the framing of which projects out to form a vertical wall suitable for windows or other openings.

A rectangular groove across the width of a board or plank. In interior decoration, a special type of wall treatment.

Short stud such as that used between a door or window header and the top plate.

In architecture: A perpendicular supporting member, circular or rectangular in section, usually consisting of a base, shaft, and capital. In engineering: A vertical structural compression member which supports loads acting in the direction of its longitudinal axis. Some columns are referred to as wind columns or wind beams and actually are flexural members and act like beams even though they are oriented in a vertical plane.

One of a pair of horizontal boards nailed to posts set at the corners of an excavation, used to indicate the desired level, also as a fastening for stretched strings to indicate outlines of foundation walls.

The finish materials in a building, such as moldings applied around openings (window trim, door trim) or at the floor and ceiling of rooms (baseboard, cornice, and other moldings)

A rafter that spans the distance from the wall plate to a hip, or from a valley to a ridge.

(a) A beam placed perpendicular to joists and to which joists are nailed in framing for chimney, stairway, or other opening. (b) A wood lintel.

A solid, tight closure of a concealed space, placed to prevent the spread of fire and smoke through such a space. In a frame wall, this will usually consist of 2 by 4 cross blocking between studs.

Expansion joint

A bituminous fiber strip used to separate blocks or units of concrete to prevent cracking due to expansion as a result of temperature changes. Also used on concrete slabs.

To nail perpendicular to the initial surface or to the junction of the pieces joined. Also termed face nailing.

Exterior wall of a building that is supported by the structure and carries no part of the vertical load except its own. Curtain walls must be designed to withstand wind loads and transfer them to the structure.

A protective sleeve or pipe typically used for installing electrical wiring.

Nailing in such a way that the nail heads are not visible on the face of the work—usually at the tongue of matched boards.

Band joist (Rim joist)

A wooden joist running perpendicular to the primary direction of the joists in a floor and closing off the floor platform and the outside face of the building.

A scalloped roof structure of reinforced concrete that spans in one direction as a barrel vault and in the other as a folded plate.

Suffix designating the size of nails, such as 6d (penny) nail, originally indicating the price, in English pence, per 100 nails. Does not designate a constant length or size, and will vary by type (e.g., common and box nails).

Two sloping surfaces meeting in a horizontal ridge, used between the back side of a chimney, or other vertical surface, and a sloping roof.

Material removed due to poor structural properties or saturated conditions below subgrade.

Underlying material to which a finish is applied or by which it is supported.

Leading brand of gypsum panel for interior wall and ceiling surfaces, developed and improved by United States Gypsum Company. There is only one SHEETROCK brand Gypsum Panel.

In stairs, the net width of a step or the horizontal distance covered by a flight of stairs.

Measurement in height of an object; the amount it rises. The converse is "fall."

Concrete or other material that is poured and set at a site different that where it will be installed.

coach gate"; also called a "carriage porch" is the architectural term for a porch-like or portico-like structure at a main or secondary entrance to a building through which a horse and carriage (or motor vehicle) can pass in order for the occupants to alight under cover, protected from the weather.

Chamber in which the pressure of the air is higher (as in a forced-air furnace system) than that of the surrounding air. Frequently a description of the space above a suspended ceiling.

Exactly perpendicular; vertical.

A pasty material used as a cement (as for setting tile) or a protective coating (as for thermal insulation or waterproofing)

Ledger Strip (Board)

Strip fastened to the bottom edge of a flush girder to help support the floor joists.

Annular Ring Nail

aka: rink-shanked nail - A deformed shank nail with improved holding qualities specially designed for use with gypsum board.

Method of framing outside walls in which studs extend the full length or height of the wall.

Narrow strip of wood, plastic, metal or gypsum board used to conceal an open joint.

To build out one or more courses of brick or stone from the face of a wall, to form a support for timbers.

Metal-mesh lath cut into strips and bent to a right angle. Used in interior corners of walls and ceilings on lath to prevent cracks in plastering.

Change in shape of a body brought about by the application of a force internal or external. Internal forces may result from temperature, humidity or chemical changes. External forces from applied loads can also cause deformation.

Member or means of supporting a finished surfacing material away from the structural wall or framing. Used to level uneven or damaged surfaces or to provide space between substrates. Also an element for mechanical or adhesive attachment of paneling.

Forcing out of plumb of structural components, usually by wind, seismic stress or thermal expansion or contraction

A felt which is impregnated with tar or asphalt.

Small piece or block of wood that bridges several members or provides a connection or fastening between them.

Fire-resistant wall that isolates the elevator, stairwell and vertical mechanical chase in high-rise construction. This wall must withstand the fluctuating (positive and negative) air-pressure loads created by elevators or air distribution systems.

A small masonry block laid with the top close to the ground surface to receive roof drainage from downspouts and to carry it away from the building.

Slender structural element that resists compressive forces acting lengthwise.

Double joists or rafters framing the opening of a stairway well, dormer opening, etc.

Tongue-and-Groove Joint

Joint where the projection or "tongue" of one member engages the mating groove of the adjacent member to minimize relative deflection and air infiltration; widely used in sheathing, flooring and paneling. Tongues may be in "V," round or square shapes.
