Answer 6

Chute, pump or crane

Question 7

When can formwork for a suspended slab be removed?

Answer 7

When the design strength has been reached.

Question 8

List four options for curing a suspended slab.

Answer 8

Ponding, wet covering, mechanical barriers and curing compounds

Question 9

In what sequence does form stripping usually take place?

Answer 9

1) Bem sides, perimeter infill, small sections then large sections

Question 10

The tagline for a flyform must be what diameter and rope type?

Answer 10

5/8” Polypropylene

Question 11

What should workers inspect Aluma Beams for before use?

Answer 11

Wear, corrosion, deformity.

Question 12

What factors can affect the scheduling of a suspended slab?

Answer 12

Availability of materials, delivery of material,s and coordination with sub trades.

Question 13

What is an alternative to the Column Capital?

Answer 13

Drop panel, easier to form out of plywood, using similar system as for beams. Soffit plywood rests on the joists and stringers and finally a shore head.

Question 14

The underside of a slab is known as:

Answer 14

Soffit

Question 15

The material used to form the slab known as:

Answer 15

Decking

Question 16

Flyforms are known by their name because:

Answer 16

They are crane-lifted or flown

Question 17

Gang forms are mostly used for:

Answer 17

Forming walls

Question 18

Slab tables are mostly used for:

Answer 18

Forming suspended slabs

Question 19

Modern slab table consists of:

Answer 19

Alum. truss shoring., stringers, and/or joists and screw jacks for leveling and a plywood deck.

Question 20

Alum beam

Answer 20

Standard name for an aluminum extrusion that is in the shape of an I, includes 2x2 or composite material in the top and a groove in the bottom that will accept the head of a bolt to fasten the beam to the scaffold.

Question 21

Most systems consist of what set up?

Answer 21

Scaffold and shoring on a mudsill, with beams and joists providing the support for the decking.

Question 22

Who must ALWAYS design fly forms?

Answer 22

Designed by a P.ENG, and constructed, hoisted, moved, and set strictly according to the instructions of the designer or manufacturer.

Question 23

Before placement, what should be done before placing concrete?

Answer 23

Slump test to make sure it is up to the standard of an P.Eng.

Question 24

Typically, formwork for a suspended slab can be removed after:

Answer 24

14 days, but follow P.ENG plan for disassembly and re-shoring.

Question 25

How to store Aluma beams properly?

Answer 25

Dry, well-ventilated area to prevent corrosion & damage.

Stored in a horizontal position, preferred. on a rack or a pallet to avoid bending or warping.

Question 26

To avoid delays and a smooth construction process, what factors need to be considered?

Answer 26

Material availability, and delivery of (rebar, formwork), coordination with other trades (electrical, etc), weather conditions, and site-specific constraints. Efficient planning and scheduling will optimize the installation of suspended concrete slabs.
