Air Barrier• Tyvek – creates a membrane around the
structure in which air can not freely permeate through.
Attic Ventilation• Attic ventilation is needed to
release any accumulated heat in the attic space out. It also allows water vapor to escape the attic.
• • Soffit –
• Ridge vent
Back Hoe
• A back hoe digs Earth material from the ground a construction site.
• The width of this bucket is 2’
Batter Boards• Batter boards are temporary boards put in
place just out side of the area where the foundation is to be poured. The batter boards help the workers locate the exact corners and edges of the foundation
• Keystone on roman arch• Centering – is used to hold bricks in place
in an arch till the mortar sets
Brick Bonds• Flemish – alternating headers and strecthers
• Running – stretchers laid continuously and on top of each other
Bulldozer
• A bulldozer is a piece of heavy equipment used to push big amount of loosened Earth around a job site. It can help level the job site also.
Code Requirements
• Window, 29” from the floor, 34” wide x 58” long = 13.69 sq. ft.
• IBS requirements – less than or equal to 44” from AFF with a minimum dimension of 36” and Sq Ft area of 9.
• Window is less than 44” AFF , has a 58” long dimension, and is 13.69sq ft.
Concrete Joint
• A concrete joint tries to make the cracks that will occur in concrete occur in a place that the designer chooses. Need crack not in one
• Isolation joint (column from slab)– used to allow columns or walls to move separately of the foundation
Concrete Masonry Unit (CMU)
• A CMU is block made from concrete that is meant to be laid as if it were brick.
• Its typical dimensions are 7 /58” x 7 5/8” x 15 5/8”
• 1 block = 3 bricks
Door
• Transom – a window immediately above a door
• Sidelight – a window immediately besides a door.
Electrical Components• Power pole – holds electrical
wires for safe transmission of electricity from the power plant.
• Service head – brings electricity from the power lines to the meter base.
• Meter – Measures how much electricity a house uses.
• Service panel – Distributes electricity to the circuits within a house.
• Duplex receptacle – Is what you plug appliances into so they can receive power.
Front End Loader• Used for picking up
earth material or debris from a job site and moving it.
• Is distinguished from a bulldozer by its ability to pick up material and raise it ton elevated height.. Its is different from a back hoe in that it can not dig.
Gypsum Board
• Gypsum board is a panel made from calcified rock and fibers sandwiched between two paper sheets.
Heat Pump
• One advantage – they heat or cool a building quickly
• One disadvantage – they are loud.
• Compressor/condenser – pulls heat from the air to distribute through out the building
• Air Handling unit – mixes outside and inside air
Insulation- retards the flow of heat into the building in the summer and out of the building
in the winter
• Foamed – is a spray foam that is sprayed into the area where it is to be laid. Densely packed and has a high R – value.
• Batt – rock wool or glass wool , light and fluffy can be cut with a knife.
• Rigid board – used where insulation thickness matters. Is a panel installed like sheathing that provides insulation.
• Loose fill – is glass fiber, or rock wool with a
fire retardant cellulose coating. It is blown into place.
Lintel
• Lintel – A steel beam that is used to hold up bricks around an opening. Bricks do not span well with out support from beneath.
Mortar 2
• tooled• 3/8” in width• Retaining wall • M strength because its in contact with the
ground.
OSB
• Oriented Strand Board is strand like wood particle that are glued and the compressed into layers of 3 to 5. the strains are orient perpendicular to each other from layer to layer.
• It is manufactured by laying the long strand like particle down in an alternating orientation with glue and then compressing the layers together.
• Lavatories - A sink used for washing with a means of draining. Size pipe used to flush the water down is a 1 1/2” diameter pipe.
• Water closet – a toilet, flushed solid waste, piping size required is 3”
Plumbing
VTR
• Vent Through Roof – provides air to the sewer pipes so that water from the P trap is not sucked out.
Plywood• Plywood is a wood panel product.
It is made up of thin veneers glued together with the front and back grains facing the same direction but with the inner veneer laying perpendicular to layer beneath it.
• Plywood is made from rotary sliced logs that produces a continuous thin veneer from a log.
• Veneer – a thin layer of wood having been rotary sliced from a log. Produces a nice grain finish.
Radiant Barrier• Definition – reduces the flow of solar
heat by reflecting infrared radiation with an aluminum foil. Goes over the rafters and beneath the sheathing
Rebar
• Size #4• Deformations purpose
is to allow the bars to grip to the concrete so the bars do not slip.
Steep Roof Drainage
• Gutter – usually a metal tube on the eave of a roof that collects rain water.
• Downspout – directs the water collected by the gutter to the splash block on the ground.
• Splash block – receives the water from the down spout. Prevents erosion of the soil below the down spout.
Steep Roof Materials
• Underlayment – helps provide extra protection from
water getting into the sheathing and then attic.
• Clay
Steep Roof Terms• Ridge – the highest point on a roof where
the sides of a roof intersect.
• Valley – the area where the slopes of two adjacent roofs come together.
• Eave – the low level edge of a roof
Steep Roof Cont
• Rake – the low sloping edge of a roof
• Soffit – the area underneath where a roof hangs over, is usually perforated for ventilation.
Steep Roof Cont
•Fascia – the area at the bottom of a roof that faces outward. Is attached to the butts of the rafters.
•Building without a Facia – does not have a bottom rail that is attached to the rafters
Vapor Retarder
• Prevents water vapor from getting into the insulation. Goes on the warm in winter side.
Waterproofing
• Waterproofing – this one is liquid applied water proofing. Water proofing prevents water from penetrating into the basement.
Windows
Awning – pivots from the top horizontal axis and swings outward
• Casement – pivots from the side and opens outward
