H4 - Build Wall systems LT #1

Question 1

Define platform wall framing:

Answer 1

Walls are constructed horizontally using the floor as a platform, then stood up.

Question 2

What type of wall does not use studs?

Answer 2

S I P - Structural Insulated Panels

Question 3

What is a partition wall?

Answer 3

An interior wall that divides the room within an occupancy

Question 4

What is a load-bearing wall and are all interior walls non-load bearing?

Answer 4

A wall that supports a roof or floor load is load bearing

Question 5

Describe a plumbing wall

Answer 5

Specifically framed wall to accommodate large plumbing pipes

Question 6

Weaving insulation between staggered studs and the use of a res-bar will help to:

Answer 6

Reduces sound transmission

Question 7

What is a point load?

Answer 7

A CONCENTRATED load, such as where a beam or girder truss rests on a wall

Question 8

How does a party wall differ from a partition wall?

Answer 8

A party wall is between two occupancies, whereas a partition wall is within an occupancy

Question 9

What is the purpose of a shear wall?

Answer 9

To provide lateral support against wind, seismic & other forces

Question 9

What is the purpose of a shear wall?

Answer 9

To provide lateral support against wind, seismic & other forces

Question 10

What is a manuf. prefab wall?

Answer 10

Built-in an automated plant and then shipped to site

Question 11

What sizes do prefab walls typically come in?

Answer 11

Framed & sheathed, typically up to 20 ft. lengths & up to 11 ft height.”
Transportation concerns limit the wall heights.

Question 12

What are the advantages of prefab walls?

Answer 12

1) Built using automated truss plant technology, producing walls that are true and square
2) built regardless of weather conditions
3) Less waste material on the job site, the building goes quicker

Question 13

Structural insulated panels are made how:

Answer 13

Sandwiching rigid foam insulation between panels of OSB, plywood, cement board, or metal.

Wall panel provides system that includes sheathing, structural framing, insulation and vapour barrier in one.

Question 14

In a SIP, which size wall panels do not use studs?

Answer 14

4 and 6-foot walls, the structural component is mainly supplied by the panels’ sheathing.

Question 15

How are SIP joined together?

Answer 15

Using top & bottom plates and with splines between the panels.

Question 16

6” SIP panels provide an overall R VALUE of what?

Answer 16

R-24

Question 17

What advantages of SIP are:

Answer 17

1) Reduced wall framing time
2) High levels of insulation
3) Reduced thermal bridging
4) Increased lateral and compressive structural

Question 18

Plumbing walls can be constructed with what lumber?

Answer 18

These walls can be constructed with 2x6 studs, they can also be constructed with two sets of 2x4 studs on the flat on either side of a 2x6, 2x8 or 2x10 plate

Question 19

2x4 studs on the flat are weaker, how can you secure the opposing studs together?

Answer 19

With a plywood cleat at mid height

Question 20

Sound waves are conducted through walls by:

Answer 20

Vibrating the studds,

Question 21

How can you significantly reduce sound transmission?

Answer 21

Staggered stud walls with insulation weaved in between

Question 22

Hip roofs often have all exterior walls load bearing, or non load bearing?

Answer 22

All exterior wall are load bearing

Question 23

Gable-end walls are load-bearing or not?

Answer 23

Gable-end walls bear a small roof load and are treated as a special cases of load bearing.

Question 24

Load-bearing walls need bracing and extra framing, this is done to support & transfer overhead loads down to the ______?

Answer 24

Foundation (Known as the Load path)

Question 25

Most load-bearing walls support relatively uniform loads, when a load is concentrated, it is called:

Answer 25

A point load

Question 26

Non-load-bearing walls only need to support:

Answer 26

Wall finishes, sometimes items such as cabinets & do not usually require lintels in the header space over the window & door openings. The stud sizing can be reduced compared to load-bearing walls.

Question 27

In order to achieve the required fire & sound transfer ratings, party walls may use:

Answer 27

Alternating studs, double studs, concrete blocks, or multiple layers of drywall.
