19 mm
What size tire slots are required in the panels
6 x 25
How are the tie slots made?
Using a template and a router With a carbide bit 6 mm
What is the safe working load for the ties?
Ten, MPA
What is the purpose of whaler bars
Supports the wall forms
Describe four methods of corner connections for strip ease forms
Metal hinge, steel corners, strap, hinges, and angle iron bolted to the form panels
What are the two standard sizes of panels for the strip ease system
600 mm x 2400 mm ( 2 x 8) and 1200 mm x 2400 mm ( 4 x 8)
What are the three pieces of equipment required to cut the slots into the form ply?
Template router, and router bit
What is the convenience of using corner forms with metal hinges, and a rod passing through
Forms can be folded flat together for easier handling and storage
How are the Whaler bars removed
Strike with a hammer
Why are the wall tiles design to break off 6 mm inside the concrete wall?
To leave a hole to be filled with caulking or cement plastic it prevents tiles from rusting out which may cause the wall to leak
Why should the whaler bars joints not line up with the plywood panel joints?
For strength and to prevent bulges
If pilaster’s are deeper than 250 mm, why should ties be used at right angles to the projection
So the sides of the pilaster’s do not break out
Is the bottom plate set on the concrete line? Why or why not?
No the thickness of the form away from the concrete line 19 mm or 3/4 and it provides extra lateral support
What size of nails should be used to fasten the panel to the plates?
50 mm common nails
Should both the inside and outside form panels be braced why or why not
Outside only
How many bottom plates are required on outside form panels?
One on one side along the bottom
How far beyond the joint in the strip ease panel must the Waler bar extend?
One Tie passed
Describe a grade beam
Low foundation wall at ground level, and as usual, he supported at individual points by Baring piles
Two methods of supporting formwork at the proper elevation
2 x 4 steaks or 38 x 89
Sleepers directly on footing
Each whaler bar should catch at least how many wall ties on a straight wall
Three
What are two methods of providing avoid under grade beams to allow for heaving and expansion of the soil?
Void form cardboard, and Styrofoam excavating
How could the treated plywood strips be fastened to the sides of a grade beam before backfilling?
Power, actuated, tools, hammer drill
Prior to aligning a row of wall panels one should check that the corners are
Plumb
A row of wall forms is aligned at the top by using a
Stringline
Braces used to secure the tops of wall. Forms in alignment should be space at ___ intervals.
2-3m
Interior wall forms are aligned by using
Spreaders
The bottoms of exterior wall forms are aligned by
Using a kick plate/nailer/runner
What block outs are treated with form oil to?
Prevent bonding and swelling
Round holes through concrete walls can be achieved by using_____ As block outs
Tubes
Square or rectangular block outs are tapered only when they
Must be removed
Layouts for locating any block out, should be checked
Before setting inside forms
Tubes used to form round block outs are secured to the forms by
Securing plugs to the forms
Bulkheads are used to form_____ Two concrete walls
Vertical ends
Keys and bulkheads must be attached to bulkheads with the wide part of the keyway toward the
Bulkheads
Bulkheads gain additional resistance to the pressure of concrete when provided with
Kickers (nailers)
Rough bucks should be made with____mm thick lumber
38
Key is attached to rough bucks should be nailed from the
Inside of the buck
Rough bucks for window or door frames are made
Slightly larger than the finished frame
The minimum distance from the edge of the key to the face of the concrete wall is
50mm
Deflection to the sides of bucks caused by pressure from concrete is prevented by using
Braces
Door window box must be made 4 mm to 6 mm narrower than wall thickness when using______
Strip ease form system
And residential construction anchor bolts must be embedded a minimum of
100 mm
Anchor bolts can be positioned with accuracy, if a ___ is used
