H4 - Build Wall systems LT #1 Flashcards
Define platform wall framing:
Walls are constructed horizontally using the floor as a platform, then stood up.
What type of wall does not use studs?
S I P - Structural Insulated Panels
What is a partition wall?
An interior wall that divides the room within an occupancy
What is a load-bearing wall and are all interior walls non-load bearing?
A wall that supports a roof or floor load is load bearing
Describe a plumbing wall
Specifically framed wall to accommodate large plumbing pipes
Weaving insulation between staggered studs and the use of a res-bar will help to:
Reduces sound transmission
What is a point load?
A CONCENTRATED load, such as where a beam or girder truss rests on a wall
How does a party wall differ from a partition wall?
A party wall is between two occupancies, whereas a partition wall is within an occupancy
What is the purpose of a shear wall?
To provide lateral support against wind, seismic & other forces
What is the purpose of a shear wall?
To provide lateral support against wind, seismic & other forces
What is a manuf. prefab wall?
Built-in an automated plant and then shipped to site
What sizes do prefab walls typically come in?
Framed & sheathed, typically up to 20 ft. lengths & up to 11 ft height.”
Transportation concerns limit the wall heights.
What are the advantages of prefab walls?
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
Structural insulated panels are made how:
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.
In a SIP, which size wall panels do not use studs?
4 and 6-foot walls, the structural component is mainly supplied by the panels’ sheathing.
How are SIP joined together?
Using top & bottom plates and with splines between the panels.
6” SIP panels provide an overall R VALUE of what?
R-24
What advantages of SIP are:
1) Reduced wall framing time
2) High levels of insulation
3) Reduced thermal bridging
4) Increased lateral and compressive structural
Plumbing walls can be constructed with what lumber?
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
2x4 studs on the flat are weaker, how can you secure the opposing studs together?
With a plywood cleat at mid height
Sound waves are conducted through walls by:
Vibrating the studds,
How can you significantly reduce sound transmission?
Staggered stud walls with insulation weaved in between
Hip roofs often have all exterior walls load bearing, or non load bearing?
All exterior wall are load bearing
Gable-end walls are load-bearing or not?
Gable-end walls bear a small roof load and are treated as a special cases of load bearing.
Load-bearing walls need bracing and extra framing, this is done to support & transfer overhead loads down to the ______?
Foundation (Known as the Load path)
Most load-bearing walls support relatively uniform loads, when a load is concentrated, it is called:
A point load
Non-load-bearing walls only need to support:
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.
In order to achieve the required fire & sound transfer ratings, party walls may use:
Alternating studs, double studs, concrete blocks, or multiple layers of drywall.
