Today’s ‘spot the defect’ challenge is all about best practice when installing wall plates.
Can you guess what’s wrong with the wall plates in this picture?
Drum roll please…..
Here’s what you should have spotted;
1. Wall plates should not be used in this instance because infilling is required between truss members. Instead the joists should be 'built in' or on suitable hangers.
2. Block work has been incorrectly built off the timber wall plate instead of correctly supporting the trusses off the masonry using specified truss or joist hangers.
You can find more detailed information on constructing timber roof structures in Chapter 7.8 of our Technical Manual.
