OBJ 1.1 Flashcards
Analyze the integration of architectural systems and technologies to meet project goals (A/E) As an architect you will first need to be able to resolve and detail roof, curtain wall, cladding, window, floor, and other architectural systems, while also considering the detail requirements and capabilities of individual building materials
Embed Plate
Embed plates are metal components that are cast into concrete to provide anchoring for other systems later.
Bentonite Clay
Foundations with habitable spaces must be protected from moisture intrusion. Bentonite clay is a type of clay that has unusual qualities of cohesion and sealing when exposed to moisture. Used as a waterproofing membrane at a fountain wall, it can provide an impermeable barrier to moisture intrusion from the soil. It cannot be ripped, punctured, or cracked. Bentonite clay can also be used under slabs. It is found naturally in South Dakota, Wyoming, and Montana and is mined for its unique qualities.
Glazing
Glazing is the process of installing glass in a window frame. It can also refer to the glass that has been installed through the glazing process.
Compare and contrast storefront, curtain wall, and window wall systems.
Storefront: a non-load-bearing, single-span glazing system that sits within the building structure and spans from slab to slab. Storefronts are often limited to a height of 10’ and are mostly used at the ground floor, but they can be placed at the upper levels of low-rise buildings.
Curtain wall: Non-load-bearing glazing system that “hangs” outside of the building structure and can span up to 20’ (or even further with reinforcement). Curtain walls are appropriate for use in the higher floors of tall buildings, and because curtain walls often hang outside of the building structure, they can span between floors.
Window wall: a non-load-bearing glazing system that spans from slab to slab, similar to storefronts. Unlike storefronts, window wall systems are rated for use in upper floors and can provide a look similar to curtain walls at a lower cost.
Weathering Steel
Often referred to as COR-TEN steel, is a group of steel alloys which were developed to eliminate the need for painting, and forms a layer of self-protective rust after several years exposure to weather.
Parging
A coat of mortar or plaster on the outside of concrete or masonry walls.
SIP
Structural Insulated Panel (SIP): two outer sheaths bonded to a core of rigid insulation.
Thermal Bridge
An area or component of an object which has higher thermal conductivity than the surrounding materials, creating a path for heat transfer.
Thermal Break
An element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials.
Tempered Glazing
A type of safety glazing that is created through a heating and cooling process. It is stronger than regular glass but is also brittle. When tempered glass breaks, it shatters into small pieces that are less likely to injure building occupants.
Laminated Glazing
A type of safety glazing that is made up of two or more glass panels held together by interlayers. When broken, laminated glazing holds together and can act as a barrier. Because of this, laminated glazing is typically used in glass guardrails.
Ice Damming
When warm air rises out of a heated space into an unheated roof and there is snow on the roof, the heat melts the snow and the water runs down the roof to the eave and gutter, where it cools and turns to ice, forming a dam where more water collects and leaks into the walls and ceilings of the building. Areas most susceptible to ice damming include roof eaves and valleys.
USCPSC
The United States Consumer Product Safety Commission is an independent federal agency that serves to protect the public from products that may be unsafe due to risk of fire, mechanical failure, chemical exposure, or electrical malfunction.
Float Glass
A sheet of glass made by pouring molten glass onto a sheet of molten metal, usually tin. Also called annealed glass. Float glass is very smooth and free from distortions.
Laminated Glass
A type of safety glass consisting of two or more pieces of glass, with layers of polyvinyl butyral resin sheet interlayers. It is good for security because the plastic interlayer holds the glass together, instead of shattering. Laminated glass is also a better sound protector than regular glass, due to the inner layer.
Spandrel Glass
An opaque glass available tinted or with a variety of coatings. It can be heat-treated or laminated, and is available as insulated glass units. Insulation and vapor retarders can be added to spandrel glass.
Low-E Glass
Low-E or low-emissivity glass is a hard or soft metallic coating that provides more reflectivity for shortwave solar energy that strikes the glass at a high angle of incidence during summer, and permits warmth to enter in winter when the angle of incidence is lower.
Reflective Glass
Reflective glass is coated with a very thin layer of metal with the primary purpose of reflecting radiative heat.
Polycarbonate
A group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent.
Heat-Strengthened Glass
Float glass that has been heated and cooled for strength. It is about twice as strong as annealed glass. When broken, glass pieces tend to break in larger pieces. It is not considered a safety glass.
Electrochromic Glass
Glass whose light transmittance is altered by the application of an electric current.
Insulated Glass
Insulated glass, is two or more panes of glass together with a layer of air in the middle for insulating purposes. Also called insulated glass units (IGUs). Insulated glass units are hermetically sealed and contain desiccants for dehumidification. The air space in between is often filled with an inert gas such as argon.
Patterned Glass
To obscure vision and reduce light transmission.
Glazier’s Points
Small metal pieces that hold a piece of glass in place while putty is applied.
