G8 - Describe Architectural Formwork Flashcards
How are slip forms held together?
Yoke
What type of buildings are built using the slip-form method of construction?
Tall structures such as bridge piers, water towers, elevator shafts, and water silos.
What rate are vertical slip forms moved?
8 to 18 “ per hour.
Where is the finishers scaffold on a slip-form construction?
Below & outside
What depth of the layers is used when placing concrete?
12 Inch
How are curved walers built?
3 pieces of lumber, laminated with offset joints.
What is the purpose of a finisher’s scaffold?
Repair and touch up
Basic principal of slip forming is:
Form slips by or away from previously placed concrete. Concrete must set enough to support its own weight as the form moves by.
Sides of slip form are held against the pressure of fresh concrete not with ties but:
Yoke or a U-shaped brace.
Yokes support the walers, walers support:
Walers support the form sheathing.
What kind of sheathing will a round building use?
Multiple layers of thin sheathing.
Placing concrete in slip forms happens how many hours per day?
24 hours, until the project is completed.
