22. Doors Flush Door 6 Panel Door Top Rail Stile Panel Lock Rail Bottom Rail
23. Doors Continued Sidelight Transom A Transom is a small window directly above a door. A Sidelight is a tall and narrow window alongside a door.
24. Electrical Components Transformer Electrical Meters Electrical Meters measure the amount of electricity used. A Transformer is an electrical device that converts voltage of alternating current and sends it to the Service Head. Service Head The purpose of a Service Head is to send electricity from the outdoor lines to the meter base.
25. Electrical Components Cont. Service Panel Duplex Receptacle A Service Panel ties all of the circuits in a building to the main power supply. Breakers are used to prevent overloading. A Duplex Receptacle allows two appliances to be plugged into an electric circuit.
29. Front End Loader A Front End Loader is a type of tractor with a large metal bucket attached. It is used for carrying material from one spot to another and dumping the material in a truck or trench excavation.
30. Gypsum Board Gypsum Board Gypsum Board is an interior facing board with a gypsum core sandwiched between sheets of paper; also called drywall or plasterboard
31. Heat Pump Compressor/Evaporator Air Handling Unit Compressor- houses a fan that moves air across coils containing refrigerant to change the temperature of the refrigerant. A big advantage of a heat pump is its ability to both heat and cool. Some disadvantages of this system are that they are relatively noisy and the ducts are bulky. An Air Handling Unit is a device used to condition and circulate air.
34. Lintel A Lintel is an angle steel piece that transfers a load for the opening of a window or door. Angle Steel Lintel
35. Mortar Concave Mortar Joint (Tooled) – Dudley Hall The mortar type is S or N type. Mortar Joint – Residential Home The mortar type is S or N
36. Oriented Strand Board OSB Oriented Strand Board (OSB) is a building panel composed of long strands of wood oriented in specific directions and bonded together under pressure. OSB is a non-veneered panel product.
37. Plumbing Lavatory Water Closet A water closet uses a 3” drain pipe, and a lavatory uses a 1 ½’’ drain pipe.
40. Plywood Plywood is a type of Manufactured Wood made from thin sheets of wood , called plies or wood veneers . The layers are glued together so that adjacent plies have their wood grain at right angles to each other for greater strength. There are usually an odd number of plies, as the symmetry makes the board less prone to warping. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength. A veneer is a thin covering over another surface.
42. Rebar This is #5 rebar which means it is 5/8 in. The deformations on the surface of the rebar create friction between the steel and the concrete once it is poured and hardened. Rebar gives concrete tensile strength.
45. Steep Roof Materials Underlayment Underlayment Underlayment or Tar paper is a heavy-duty paper used in construction. Tar paper is made by impregnating paper with tar, producing a waterproof material useful for roof construction. Roofing felt, one common type of tar paper, is a glass fiber or polyester fleece impregnated with bituminous material (tar, asphaltic bitumen); it is produced in roll form.
46. Steep Roof Materials Cont. Clay Tile Roof- clay is used to fabricate. Aluminum sheets are used to fabricate these metal shingles. Metal Shingles
50. Steep Roof Terms Ridge- the top, flat edge of the roof Rake- slanting edge of roof; connects the eave and the ridge. Valley- where two components of a roof form a low point. Eave- the lowest flat edge of a roof. Fascia- front edge of an over hang below the eaves. Soffit- the bottom edge of an overhang. Ridge Valley Fascia Soffit Rake Eave
55. Weep Hole Weep Holes Weep holes are spaces between two bricks that are not filled with mortar. They allow water that penetrates the brick veneer to escape easily.
56. Welded Wire Fabric Welded Wire Fabric Welded Wire Fabric- Reinforcement of a flat concrete slab. This WWF is 6 x 6 in.
57. Windows Double Hung Window- two moving panels. Sliding Window- slides horizontally.
