PART 2 (A) CONSTRUCTION METHODS
OUTLINE the Construction Methods to change the flooring from Sheet Flooring to Tongue & Groove.
READ & REFER: Text Book 2 – Section 6 Framing -Topic 6.2 Flooring
Consider the following: Type your answers in the sections provided below.
Describe the methods of laying Sheet Flooring
Preparation:
• Ensure that the sheet flooring is cut and laid out properly, allowing space for expansion as per manufacturer recommendations.
Installation:
• Position the sheets to cover the joists, ensuring proper alignment.
• Secure the sheets with nails or screws, adhering to the spacing guidelines (e.g., approximately 150 mm along edges and 300 mm at intermediate points).
• The sheets are to be fixed with adhesive where specified, and the edges must be secured as the diagram indicates.
• Expansion gaps are necessary, especially for floor widths over 6 m, to prevent buckling due to moisture changes.
Considerations:
• The document emphasizes proper edge nailing, cramping to ensure boards are tight against each other, and pre-drilling for areas susceptible to splitting.
Describe the methods of laying Tongue & Groove Flooring
Preparation:
• Similar to sheet flooring, T&G boards must be acclimatized and checked for moisture before installation. Ensure the subfloor is ready.
Installation:
• Boards should be secret-nailed or glued, starting from one side and working across the room. Nails should be driven into the tongue at a slight angle to hide them.
• Use the diagrams provided in the document, which demonstrate the correct nailing patterns, including proper spacing and where to apply adhesives.
• Cramping tools may be used to ensure the boards are tightly fitted together.
• Expansion joints should be left around the perimeter.
Considerations:
• Pay special attention to how boards are laid around wall junctions to allow for natural expansion and contraction. The diagrams show details like secret nailing to reduce visible fasteners.
Explain what needs to be considered with the position of the floor Joists with Fitted Floors (Tongue and Groove) – include examples from the NCC
Joist Placement:
• Floorboards should be laid perpendicular to the joists, ensuring that joints line up directly over the joists to provide adequate support.
• Diagrams show that boards should overlap joists at ends, and additional blocking may be required if the joints do not naturally align over a joist.
• The recommended practice involves placing nails at specific intervals to secure boards along the joist lines. For example, the diagrams suggest specific nailing patterns to ensure stability.
• The structural plywood sheet flooring should be laid with the long edges perpendicular to the joists for better load distribution.
• NCC Example: In accordance with the National Construction Code (NCC), floor joists may need to be positioned at specific intervals to meet structural requirements. For example, in residential construction, floor joists for tongue and groove flooring may need to be spaced at intervals of 450mm to 600mm apart, depending on the load-bearing capacity required for the particular application.
Describe why the flooring was changed
Structural Integrity and Moisture:
• The standards and conditions for different types of flooring, such as timber, plywood, and engineered boards, and indicates how each performs under varying conditions. Changing the flooring might have been necessary to ensure compliance with standards related to moisture resistance or load-bearing capabilities.
Adherence to Australian Standards:
• The switch to flooring materials that better comply with AS standards (e.g., AS 1684) would likely ensure safety, durability, and longevity of the flooring system.
Provide information on what the changes and modification would need to be made to the drawings and its notes
Material Specifications:
• Update the material annotations in the drawing to reflect the new choice (e.g., specifying plywood instead of T&G or vice versa).
Fastening Details:
• Modify drawing notes to specify the correct nailing and adhesive techniques visible in the diagrams. For example, include notes on secret nailing patterns or recommended expansion gaps.
Joist and Blocking Adjustments:
• Add diagrams showing the necessary blocking or changes in joist spacing to accommodate changes in material or installation method.
Expansion Gaps:
• The diagrams highlight the importance of expansion gaps, so ensure these are clearly marked and specified on the drawings.
List the references to the Timber Framing Code & the Steel Framing Provisions
