  11. 11. Concrete Joints<br />Control joint-(with crack running from it) a groove made in concrete to allow cracking.<br />Isolation joint-(between slab and brick wall) a space between a wall or structure and an adjoining concrete slab filled with a compressible material to allow expansion and contraction between the concrete and the structure.<br />
  12. 12. Concrete Masonry Units<br />Here are CMU’s on top of modular brick. 3 courses of modular brick equal one of CMU’s. <br />Here are two different sizes of CMU. The bottom two are 8 in. blocks while the top level is two 4 inch blocks.<br />
  13. 13. Decorative CMU<br />The bottom blocks are split blocks.<br />
  14. 14. Doors<br />Transom- orange circle<br />A window above a door.<br />Sidelight- blue circle<br />A window on the side of a door.<br />Flush door<br />Green circle- top rail<br />Red- panel<br />Blue- stile<br />Orange- lock rail<br />Yellow- bottom rail<br />
  15. 15. Electrical Components<br />Top Row: Left to Right. Transformer, Meter(red circle), Service Head(green circle), Service panel. <br />Bottom left: Duplex receptacle. <br />The power travels from the high voltage line into the transformer where the voltage is decreased. Power then runs into the service head located on the building, through the meter, which records electricity used, and into the service panel. The service panel controls the circuits in the house and prevents them from overloading. From the service panel the power travels on individual circuits containing duplex receptacles.<br />
  16. 16. Framing Elements<br />Anchor bolt—Red circle<br />Sill plate – Blue square<br />Floor joists – Green circle<br />Subflooring – Purple square<br />Sole plate – yellow square<br />Stud – Orange circle<br />Top plate – Aqua circle <br />Ceiling joist – Brown circle<br />Rafter – Black circle<br />Roof decking – Green square<br />Sheathing – Pink square <br />
  17. 17. Front End Loader<br />Pictured on the right is a front end loader. It is a wheeled or tracked machine with a large bucket used for moving and loading large quantities of earth or material. <br />
  18. 18. Gypsum Board<br />Also known as sheetrock or drywall, it is used as an interior facing material. It consists of gypsum material sandwiched between a paper back and front. It is nailed or screwed in place and the joints are taped and plastered. <br />
  19. 19. Heat Pump<br />The photo on the left is that of a heat pump compressor and the photo on the right is the air handling unit. <br />The compressor moves outdoor air across coils to change the air temperature. The air handling unit forces the air throughout a system of ducts to control the temperature of the house. One advantage is an increase of efficiency by a factor of about 3. A disadvantage is the fact it is very noisy. <br />
  20. 20. Insulation<br />Batt/Blanket Insulation<br />Rigid foam board<br />Insulation is used to slow the conduction of heat through the walls, roof, and floor of the house.<br />
  21. 21. Lintel<br />Highlighted by the green rectangle is a steel lintel. It is used to provide added strength across the opening of a door or window.<br />
  22. 22. Mortar<br />Below is an extruded 3/8 “ joint. It is neither tooled or troweled. Type N mortar was probably used.<br />Below is a concave joint. It is a tooled joint, apx 3/8 “. This is the base of an arch, however it is most likely a veneer wall. Type N was probably used.<br />
  23. 23. Oriented strand board<br />Strands of wood, oriented in the same direction and plied together with pressure. Manufactured in 4x8 sheets and used for sheathing and subflooring. <br />
  24. 24. Plumbing<br />Top left: Kitchen sink. 2” drain pipe<br />Top right: Plumbing vent (in green circle)<br />Bottom left: <br />Green- Shower/tub. 2” drain pipe<br />Yellow- Water closet. 3” drain pipe<br />Red- Lavatory. 1.5” drain pipe<br />
  25. 25. Plywood<br />Veneers(thin slices of wood) of wood glued together and formed under pressure. The veneers are usually laid at right angles to each other to help resist warping. <br />
  26. 26. Radiant Barrier<br />Highlighted in the green circle is a radiant barrier. It is used to block out the heat of radiation from the sun. <br />
  27. 27. Rebar<br />Highlighted by the yellow circle is #5 rebar. It is 5/8” diameter. Rebar is steel rod used to reinforce concrete. The surface deformations are to increase the surface area of the rod and allow a better bond with the concrete.<br />
