Also, such a support made from steel, aluminum, or other material. Air Barrier - A component of the building envelope system that prohibits air leakage into a building and reduces the risk of condensation build up. House wrap and fluid-applied air barriers are examples. Anchor Bolt - A threaded bolt, usually embedded in a foundation, for securing a sill, framework, or machinery. beam - A horizontal structural member, such as a girder, rafter, or purlin, that transversely supports a load and transfers the load to vertical members, such as columns and walls Bond Breaker - A material used to prevent adhesion between freshly placed concrete and the substrate. column - A long, relatively slender, supporting pillar. A column is usually loaded axially in compression. Curtain Wall - The exterior closure or skin of a building. A curtain wall is nonbearing and is not supported by beams or girders.Dampproofing - An application of a water-resisting treatment or material to the surface of a concrete or masonry wall to prevent passage or absorption of water or moisture. Can also be accomplished by using an admixture in the concrete mix. Does Professor Palmer love rebar - You should know this question :) Envelope - A term used to denote the extreme outside surface and dimensions of a building. flashing - A thin, impervious sheet of material placed in construction to prevent water penetration or direct the flow of water. Flashing is used especially at roof hips and valleys, roof penetrations, joints between a roof and a vertical wall, and in masonry walls to direct the flow of water and moisture. How do we find Linear Foot? - Multiply the number of objects we are looking for by the length # * L How do we find Square Feet - Multiply the number of objects we are looking for by the length and height # * L * H How do we know where to find dove tails - From lab - Assignment 5 - we learned that there will always be two dovetails in corners and one that isn't How many objects can dowels support? - Tend to support two or more objects How many objects can rebar support? - Tend to support one object If the beam is not the exact length what do we do? - We have to contact the manufacture, inform him of the problem, and wait until he can cut one to the exact dimension. If you have a W12x40 beam that is 20 ft long, how much does it weigh in tons? - .40 tonsJoist - A piece of lumber two or four inches thick and six or more inches wide, used horizontally as a support for a ceiling or floor.

Load-bearing Wall - A wall specifically designed and built to support an imposed load in addition to its own weight. Metal Framing - Metal framed partitions commonly used for fire-rated construction around columns and at beams. On the job site, you notice that the beams that you ordered for the project are too long. You inform your boss about the situation and say that "we could cut it to the dimension we need it to be" What is wrong with this - Beams cannot be cut to the exact dimension on the job site. they have to be the right size when they come straight from the manufacturer Sheathing - Plywood, waferboard, oriented strand board, or lumber used to close up side walls, floors, or roofs preparatory to the installation of finish materials on the surface. The sheathing grades of lumber are also commonly used for pallets, crates, and certain industrial products. storefront sash - An assembly of light metal members that form a frame for a fixed-glass storefront. Tilt wall panels are typically cast with the interior face down on the slab or cast bed - False - it is the opposite, with the exterior wall facing down Tilt-up Construction - A method of concrete construction in which members are cast horizontally at a location adjacent to their eventual position and tilted into place after removal of forms.Vapor barrier - Material used to prevent the passage of vapor or moisture into a structure or another material, thus preventing condensation within them. Veneer - A masonry facing attached to the backup, but not so bonded as to act with it under load. What do beams support? - Any structure above it What is the minimum number of floors that are required to be shored or re-shored on elevated concrete construction? - 3 Floors What supports girders? - Beams When it comes to reinforcing concrete, what rebar grade would we use - Grade 60 Wythe - Each continuous vertical section of a wall one masonry unit in thickness.
