Curtain wall
Curtain wall
" an extrior" which carries no rood or floor loads
How would you reinforce aluminium
Uses steel (rods) in mullions
What size straight edge should a layout man have
Usually a ten-foot edge is sufficient however it's length will depend on its use
Elevation
Vertical height above sea level
Commercial type
Walls made up of standardized parts by the manufacture typically used for 1-2story buildings
Custom type
Walls which are designed for one project using parts specially made for this (generally typical)
The series 1600 stock length
Was created so dealers could fab & install small and medium projects in the one and two store category
Story poles are used
When doing layout and need to duplicate measurements
When and why would you use wax
When tapping and drilling aluminum as it will not stain the finish
How are lots of curtain walls fastens
With self tapping screws and pop rivets
Two types of concrete curtain wall
-cast cured finished & delivered to site -tilt up method (cast in place then lifted into place)
Three planes of adjustment
-in/out -up/down -side/side
7 parts of curtain wall
-mullions -shear block -caps -corner Plugs -header/sills -pressure plates -dead & wind load anchors
Curtain wall became explosives in construction in
1950
A full Transit rotate
360 vertically
Sandwich type panels
A Panel made of assembly; of several materials
What size tape should a layout man carry
A fifty or 100 ft steel tape
All material before errection in is
A finished product
Story pole is
A gage or template
What must be used if bolting steel to aluminum
A gasket in between as aluminum will corrode if the steel has not been treated
Corner plugs
A neoprene plug which seals between the vert and horiz mullion
Geodetic survey
A surveyors bench mark
What finish is hard
Anodized
With Aluminum why is more thread depth required
As it is a soft metal and it stretches
Math is an important factor in layout
As tolerance is minimal therefore double checking is key
When drilling stainless steel how should the drill be set
At a slow speed so the bits do not burn out
Centreline in curtain wall is the centre of the building
At least Two cross marks will follow all the way to top floor; As structural steel or concrete may vary in length width and height
It is import to select the proper blade (tooth per inch)
Because of the different thicknesses of aluminum require different blades
Masonry walls required some methods to protect against moisture penetration; a system developed was
Cavity wall- to act as a buffer minimizing rain and penetration
If you only have a high speed drill for stainless what should you do
Click it the trigger on and off as it will slow it
Spandrel panels
Cover the exterior floor beams
Besides protections from the elements
Curtain wall should be attractive durable simple to erecting and require little maintenance
Horizontal snap on covers have and are cut to
Cut to DLO and have weep holes
D.L.O.
Day light opening
Basic function of curtain wall
Enclosure and protection which hasn't changed since they were first built
Why is it important to examine and observe the starting points/ units which have been installed
Erection of the first units exactly according the proper heights stated in the blueprints
Prefab panels meanings they can be well insulted and sealed with prevent
Excessive air and moister leakage
If the sill was stated at the base of erecting it will sit on
Flashing (angle)
Glass sandwich panels
Have edges of metal which are designed with profiles to fit components of the system being used
Pressure plates
Have pre punched holes (if more then half the c/c lands before the end of the drill another hole) these plates are also cut to the length of the mullions
Top horizontal piece is also know as
Header
Anchor back up attached to mullions are used
If intermediate (wind load) anchors are required (these fasten to the side of a very mullions and run behind it)
Horizontal pressure plates are cut to
The daylight opening dimensions
As an IW Elevation is
The height above finished floor line
Spangle finish
The osb look crisis crises
Laying out
The process of locating and marking reference lines & properly identifying the lines to the work being preformed
What attaches to the vertical mullions to support the horizontal mullions
The shear block or spigot
Bottom horizontal piece is also know as
The sill
U factor detemines
Thickness of sandwich panel
Butyl sealant will be used
To seal around the corner plug
Drilling for tapped holes in aluminum it is recommended
To use a smaller size them what the charts call for
Which lubricate will not stain stainless steel
Turpentine
Interior glazing gasket
Is a rubber stripping which is used as a barrier on the inside next to glass
Thermal break
Is a seal strip which runs the length of the vertical and horiz mullions
To establish vertical lines of two floors or more why would you use piano wire and a heavy plumb bob
It will not stretch nor break if used in a small turn buckle
Only supports it's dead weigh (designed for wind loads only) resulting in
Lighter wall sections
Matte finish
Mill finish; matte dull
Cavity walls
Minimum width is 50mm; kept free of mortar droppings with weep holes
Drain holes on snap covers
Must be installed drain holes down
A 4foot bench mark is given
On each floor which can be distributed with an engineers level or transit
What are installers urged to pay extra attention to during installation
Onsite sealing for the wall grid as deviations or omissions can result in costly rework
Closed sandwich type panel
Sandwich panels where all edges are closed (except weep holes and vent so)
Open sandwich type panel
Sandwich panels with two open edges
Curtain wall can be coordinated with the structural frame resulting in
Shorter construction times
Files for aluminum
Should be kept clean from other materials
Weep holes are
Slotted holes drilled into the horizontal/transome pressure plates
Reduction in extortion wall thickness results
in more floor space
