Question about joints for an awning over an outside door:
The sloping slated roof will be supported by a timber structure shaped
I H H H H H H B
Hope that's clear (!)
I is 75x50 bolted to the wall
x, H & S also 75x 50
B is the horizontal 92x75 horizontal timber running the length of the
x supports slating laths & the slates
What type of joint should be used:
1. at the junction of I and H - is a simple mortice/tenon joint OK &
if so what is its recommended size?
2. at junction of I and S - S here is angled. Options seem to be to
(a) rebate I to hold S (b) mortice/tenon (c) just screw or bolt S to
I've looked at quite a few porches/awnings, but have yet to find one
with enough exposed to allow me work out how joints were made at these
positions. Any information most gratefully received.
