Study Notes

Frame Construction

The height of floors is determined by client agreements, design guidelines, and town planning permits.
The height specified in design guidelines is often based on the building regulations surrounding siting and overshadowing requirements.
Town planning permits may have height restrictions to ensure compliance with local regulations.
Timber frame construction uses prefabricated wall panels, timber flooring, and roof materials built on a timber framework.
Timber components are nailed to the framework to create a sturdy skeleton for exterior walls.

Frame Components

Top Plate: The upper horizontal piece of a wall frame.
Lintel: A horizontal structural element that supports a wall or opening.
Jamb Stud: Vertical stud that forms the side of a door or window opening.
Sill Trimmer: Horizontal piece of timber that supports a window or door opening.
Jack Stud: A shorter stud that supports a window or door header.
Bottom Plate: The lower horizontal piece of a wall frame.
OSB Bracing: Oriented strand board used for bracing and sheathing.
Noggings: Short pieces of timber used to support interior walls.
Head Trimmers: Horizontal pieces of timber used to support window and door openings.
Ribbon Plate: Horizontal piece of timber that connects walls at different levels.
Corner Stud: A stud that joins two walls at a corner.
Diagonal Bracing: Diagonal pieces of timber used to provide structural support.
Load Bearing Walls: Walls that support the weight of the building.
Non-Load Bearing Walls: Walls that do not support the weight of the building.
Junction Block: A structural component used to connect different elements of the frame.

Dimensioning

Interior to interior room dimensions are used for framing.
Ground floor height standard is 2.7 meters.
First floor height standard is 2.4 meters.
Standard stud spacing is either 450 mm or 600 mm - External wall stud spacing: 450 mm, Internal wall spacing: 600 mm.
Internal load-bearing wall spacing is typically 450 mm.
Room dimensions are usually represented in four lines: Overall Dimensions (First line), Porch / Alfresco dimensions (Second line), Wall to Wall space dimensions (Third line), and Void/Niche dimensions (Fourth line).
Dimension lines are spaced at 1000 mm distances.
The internal most dimension line is kept 2500 mm away from the external wall line.
The X-axis is used to mark dimensions above (top of plan) and below (bottom of plan) the line.
The Y-axis is used to mark dimensions left (left side of plan) and right (right side plan) of the line.
All dimensions should end with a Zero (0) numeric value.

Engineering Drawings

Engineering drawings provide technical information for architects to create safe, functional, and aesthetically appealing buildings.
Engineering drawings include details of frame components, framing materials, and their connection details.
Beams are often made of PFC or timber depending on the building schedule.
Lintels are placed over windows and doors for structure.
Timber studs include Double studs (DS), Triple studs (TS), Quad studs (QS), and Five studs (FS).
PFC (Prefabricated Channels) are used where higher strength beams are required.
LVL (Laminated Veneer Lumber) is a commonly used engineered wood product for construction.
Engineering drawings provide frame component sizes using different legends.
