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
