Chapter 9 Flashcards
A wooden building frame composed of closely spaced members, nominally 2 inches (51 mm) thick, in which the wall members are single pieces that run from the sill to the top plates at the eave
Balloon Frame
A wooden building frame composed of closely spaced members nominally 2 inches (51 mm) in thickness, in which the wall members do not run past the floor framing members
Platform Frame
The rough covering applied to the outside of the roof, wall, or floor framing of a light frame structure
Sheathing
Drawings that show all the dimensional and technical information required to build a building
Working Drawings (Construction Drawings)
Serve to indicate the locations and dimensions of all walls and openings, and the exterior elevations are drawings that show the outside faces of the building
Floor Plan
A drawing that shows the relationship of parts of a building or components of a building assembly by imagining that the building or assembly has been cut or sliced. Sections are usually, but not always, in vertical orientation
Section
Shows the sizes and locations of the various parts of the foundation
Foundation Plan
Shows the sizes and locations of floor framing members
Floor Framing Plan
Shows the size and relationship of all roof framing members
Roof Framing Plan
Framing carpentry, as distinguished from finish carpentry
Rough Carpentry
The strip of wood that lies immediately on top of a concrete or masonry foundation in wood frame construction; the horizontal bottom portion of a window or door, usually sloped to shed water
Sill (Mudsill)
The parallel pieces in a floor structure
Floor Joist
In wood light framing, a structural member that spans an opening in a wall or a joist that supports other joists; in steel construction, a beam that spans between girders; in masonry, a brick or other masonry unit laid across two wythes with its end exposed in the face of the wall
Header
A wooden joist running perpendicular to the primary direction of the joists in a floor and closing off the floor platform at the outside face of the building; also called a rim board
Rim Joist/ Rim Board
The loading surface beneath a finish floor
Subfloor
A horizontal beam that supports other beams; a very large beam, especially one that is built up from smaller elements
Girder
Bracing or blocking installed between steel or wood joists at midspan to stabilize them against buckling and, in some cases, to permit adjacent joists to share loads
Bridging
A beam that supports a header around an opening in a floor or roof frame; a stud that supports a header at an opening in a framed wall
Trimmer
A metal device, attached with nails, that connects a joist to a header or beam
Joist Hanger
These are increasingly used in place of sawn joists because they can span farther between supports, they tend to be straighter, and they expand and contract less with changes in moisture content
I-Joist
A rib used to support the web of a wooden I-joist against buckling
Web Stiffener
A vertical framing block used in association with I-joists to provide reinforcement
Squash Block
One of an array of small, closely spaced, parallel wall framing members; a heavy steel pin
Stud
The horizontal piece of dimension lumber at the bottom of the studs in a wall in a light frame building
Sole Plate
The horizontal member at the top of a stud wall
Top Plate
A wall that supports floors or roofs
Bearing Wall
Interior walls of a building that supports the loads from above
Interior Bearing Wall
Walls that carry no loads
Nonbearing Wall (Partition Wall)
The clear dimensions of the opening that must be provided in a wall frame to accept a given door or window unit
Rough Opening
A stud that supports the end of a header at the side of a rough opening
Trimmer Stud
A full-length stud adjacent to a trimmer stud
King Stud
The horizontal framing member at the base of a window rough opening
Rough Sill
Diagonal members, either temporary or permanent, installed to stabilize a structure against lateral loads
Diagonal Bracing
A wall that is engineered to resist lateral forces in a building
Shear Wall
A metal device that connects a building frame to its foundation in such a way that the frame cannot be lifted up by external forces such as wind or earthquake
Hold-Down
The sloping wood or steel member that supports the treads of a stair
Stringer (Stair Jack)
A difference in elevation, such as the rise of a stair from one floor to the next or the rise per foot of run in a sloping roof
Rise
Horizontal dimension in a stair or sloping roof
Run
