23
Q

Can INTERIOR LINTELS be on flat and single?

A

Yes, only when non-load-bearing. Load bearing walls need proper load transfer to the floor

24
Q

What do cripples do besides frame the window bottom height?

A

Maintain OC for exterior and interior sheathing/finishes

25
Q

Are fillers and rough sills the same length?

A

Yes

Q

4 purposes of corner posts (L’s)

A

1) Tie walls together
2) exterior sheathing support

4) insulation space

27
Q

Where do we find stud length on blueprints?

A

Refer to ceiling height from floor to determine which studs + 3 plates must be used

Q

What is a common miscalculation when determining exterior plate locations and lengths?

A

Not accounting for 3/8 sheathing (10mm)

Q

Why are all lintels kept the same size even when not necessarily needing that much strength?

A

Consistent heights to minimize mistakes

Q

On a typical opening with two trimmers total, what is the lintel LENGTH?

A

RO + (trimmer thickness x2)

39
Q

3 ways to frame wall junctions

A

1) L
2) U
3) ladder blocked between studs to join other wall
