BCGCA3004B

1. BCGCA3004B Construct Wall Framing

3. Wall Framing • National Construction Code states that

4. What does this mean • NSW law has adopted the National Construction Code (NCC) as “Building Law” • The “Building Law” says that the methods outline in AS 1684.2 will comply with this law. • So if you follow the methods outlined in AS 1684.2, unless otherwise stated you do not need any other design assistance e.g. Engineer etc.

5. AS 1684.2 Scope Page 9 Section 1.1

6. AS 1684.2 Scope Page 9 Section 1.1 This means that this standard only applies the Residential Buildings (Class 1) or Garages & Carports (Class 10).

7. Wall Frame Members • Parts of a frame perform specific functions- supporting live & dead loads- resist Racking Forces- resist Overturning Forces- resist Sliding Forces- resist Uplift Forces -Most members provide a face to accept linings (this means that member sizes may be limited)

8. Live Load

9. Dead Load

10. Racking Forces Wind

11. Overturning Forces Wind

12. Sliding Forces Wind

13. Uplift Forces Wind

14. What is a Timber Frame • Structurally Connected Timber Members • Resist Forces • Forming a Wall Frame to meet requirements • Height • Load • Roof, Upper Levels etc • Openings

15. Timbers Generally Used • Radiata Pine • F5 • MGP 10 • Higher Grades for Lintels etc. • Oregon • F5 • Hardwood • Generally only used for Lintels etc. • Engineered Timbers • Generally only used for Lintels etc.

16. Basic Frame Components Refer page 2 TAFE Guide

17. Common Stud • Main Vertical component of the wall • Transfer Loads from Top Plate to Bottom Plate • Accept wall finishes • Straightness will affect the quality • Accept fittings & Fixtures • Driers, Shelving etc.

18. Common Studs • Vertical members placed between the plates • The set the wall height • Studs in external frames resist Wind Loads • Generally Stud sizes are 90mm or 70mm wide by 45mm or 35mm in seasoned timbers and75mm or 100mm wide by 50mm or 38mm in seasoned timbers. • Required Stud sizes can be found in AS 1684.2 Supplements (which we will look at Shortly)

19. Common Studs • May be Straightened to provide acceptable wall • Only 20% of Studs may be Straightened • Studs at sides of Openings & Supporting Concentrated Loads shall not be Crippled

20. StraighteningRefer to Page 59 of AS 1684.2

21. Confirmation of Learning • On A4 page supplied draw & label an Isometric view showing the method of Crippling Studs

22. Frame Components • Common Studs • What Consideration For Selection • Determine Required Grade – Cost v Size, Usually MGP10 • Level – Upper/Single or Lower • Select Correct Table – For member • Upper Floor Joist Spacing– Applicable to Double Storey Only • Upper Floor Load Width – Applicable to Double Storey Only • Roof Material – Tile/Metal • Rafter/Truss Spacing – Roof Panel Width • Stud Spacing – How much of Roof Panel does it carry • Stud Height – The Taller a stud the less load it can carry • Roof Load Width – Roof Panel Length Span Tables supplied – Identify Part

23. Worked Example Determining Studs • Refer to Supplied Plans • Determine minimum sizes of Studs • External Walls at rear (Single Storey Section) • At Point marked 1 • External Walls at front (Two Storey Section) • At Point marked 2 (Lower Level) • At Point marked 3 (Upper Level) Present this to your trainer for confirmation of Understanding and recording of completion of the task
