G4 - Describe Fly Form Tables Flashcards
Once a building goes over four stories of typical floors, it becomes economical to use:
Fly Forms
Slab tables are also known as:
Fly forms or as fly tables
Slab table consists of what components?
1) Leveling feet
2) Trusses
3) Joists
4) Formply
Also, column and shores.
How many times could a fly form be used in a 50-storey building?
50 times, but some floors may require unique modifications on one or more.
Slab tables (Fly forms) must be assembled according to the ?whose? specifications.
Engineer and manufacturer’s
OHS Regulates what should be included in drawings for a Fly Form, which are:
Plan view, longitudinal view, cross-section.
Weight, center of gravity, and position of pick-up points are also shown.
What is a stringer in fly form construction?
A beam that supports the formwork
Plan view in Slab table plan:
Overhead view, similar to a floor plan view in res. construction
Cross sections view in Slab table:
Easy way to reduce number of drawings, acts as a sort of schedule as wel.
Side Elevation for Slab Table:
Required for each truss, showing spacing of various members such as A-frame, location of legs, pick-up points, and direction of flights out from the building.
When is Infill required between Slab Tables?
Typically required between adjacent slab tables, between tables & shear walls, columns, and elevator shafts.
Infill formply support is based on:
Span, load & other factors.
Notes in slab table plans:
Notes clarify requirements, and reduce the amount of writing on drawings - making the drawings easier to read.
Legends in slab table plans:
Legends serve to indicate what different symbols stand for:
What is shoring?
AKA FALSEWORK
As forms are stripped, concrete will need temp. support for two possible reasons.
1) Concrete might not have reached enough strength yet to support itself
2) During construction, there are often temp. loads placed on the slab that exceed design strength.
Support provided for these two reasons is known as RE-SHORING
