Q

How would you calculate the exposure of siding

A

Actual siding size minus the overlaps would be how to calculate how much siding is exposed.

You then take full height and decide it by exposer to find number of rows.

Round to a whole row and divide height again by that number to get the true exposer of the siding

Q

A

First you need to calculate your maximum allowable exposure.

The take your max wall height and divide by maximum allowable exposure. This will give you your number of rows.

If you take the max wall height and redivide by the number of rows you will discover actual exposure of the siding.

Q

In grade beam form work. There is a method which involves stakes driving into the ground which are in line to the outside edge of the grade beam.
What are the steps in this procedure?

A

First stakes are driven to or cut off at the elevation equal to the underside of the grade beam.

Then a ledger is attached to the stakes and aligned to the beam face .

A kicker is offset by the thickness of the form panel and nailed to the ledger.

Finally the plywood form work panels are installed on top of the ledger and nailed into the kicker.

Snap ties wailers and rebar are placed, completing the opposite side of the form face

The second kicker is not nailed to the ledger which allows for grade beam form work to move as lateral concrete pressure tightens up the form work.

These are then nailed into the studs
And a fire stop can then be added aswell

257
Q

What size sheathing is used for post and beam construction. And why.

A

Post and beam construction uses large timber. This means the roof beams need to be spaced further apart to keep weight down while still providing the support required. This means the roof sheathing must be thicker to accommodate the spacing and minimize deflection.

A

Solid lumber member placed on edge such as floor joists, beams and lintels are most susceptible to shrinking.

263
Q

Which framing types have minimal concern for shrinkage problems

A

Ballon framing because stud height shrinks very little and the ribbons shrinking doesn’t create cracks or damage to finishes.

Structural insulated panels is not effected by moisture or shrinkage and the polyurethane core does not expand or contract.

264
Q

What is the danger of platform framing which is commonly built on pony walls or knee walls?

A

They have very little resistance to lateral loads imposed between the floor joists and the pony walls meaning a strong wind or an earth quake which causes this load could shift the house

Supports loads

Has larger stud spacing

And has unsupported height

266
Q

A

When it’s in a non load bearing wall above an opening.

268
Q

When determining your length for wall studs from blue prints.

A

Blue prints show ceiling height on elevation drawings. So you must deduct your bottom, cap, and top plate to find your stud length.

269
Q

If the sole plate is not flush with the outer edges of the floor frame. How much can of the width of the plate is aloud to project past the floor.

A

One third of the width of the plate may project past the floor.

This allows the walls to be straight even if the floor frame or foundation is not.

Also, where ridget insulation is applied to the outside of the rim and header joist, the wall will be flush with the insulation.

270
Q

Layout for a room is typically done in what directions.

A

Left to right (this includes the back of the room.)
And front to back.

This is done to help layout of studs fall as close to if not exactly in the joists (if they have the same O.C spacing)

Minimizing problems with load transfer, plumbing, and duct work.

271
Q

Joints in the top and sole plate can occur anywhere. But typically you want them ___________.

A

On the center of a stud. They may occur on the same stud or staggered

272
Q

How would you speed up your layout of the top and sole plates.

A

Nail them together and lay them out together.

This also minimizes errors.

273
Q

What is the cut length for a lintel

A

The cutting length of a lintel is the rough opening width plus the thickness of both trimmers.

274
Q

The first stud you lay out for a 16” on centre wall will fall at what dimension.

A

15 and 1/4 is your first stud which will make your wall 16 O.C

If you’re intersecting a wall for or you would hold your tap at the wall thickness before marking your 15 and 1/4
Once again ensuring that your 16s are O.C

275
Q

What is the joint spacing between the top and cap plates on straight walls

A

Must be staggered a minimum of one O.C spacing

276
Q

If the wall is classified as the long side of the wall. Where would you start your sheeting?

A

Flush with the end of the wall

277
Q

If the wall is classified as the short side of the wall. Where would you start your sheeting

A

The end of the sheeting should project past the framing by the thickness of the other wall. This ensures the entire exterior is sheeted evenly.

(Wall framing systems part B page 31 first paragraph.) this for the picture of it doesn’t make sense

278
Q

When nailing your sheeting. What is the spacing of nails on edge and in the field

A

Edge is 150mm o.c

And 300mm in the field

279
Q

Why would you leave a 2mm gap between your sheets of plywood?

A

To allow for expansion.

280
Q

Non-structural rigid insulation can be used as sheathing material. What are some advantages of this building practice

A

Increases the R value while decreasing the effects of thermal bridging.

This can also act as an air and moisture barrier when properly sealed.

281
Q

When nailing down the sole plate. After you have aligned the wall to the chalk line. How must it be fastened down.

A

Nails should be placed every 400mm or 16” and penetrate the subfloor AND the floor joist or headers.

282
Q

What is a rake wall?

A

A rake wall is a wall made to accommodate a sloped or vaulted ceiling. (Sloped wall)

283
