Hi to all. I am about to start my brothers verandah measuring 5 x 4.4m. Using 115*115 posts and 190*45 side beams and fascia beam. 5 metre house side connected to fascia which has been reinforced in the roof and end of fascia beam extends out onto a post. Gable roof with laserlight on top with 140*45 rafters at 900 centres. Side beam spans 5 metres over 3 posts, while 4.4 side will have 3 posts.
In previous verandah constructions, I have used simple a-frame trussed preformed on the ground and lifted it up with 2 people and placed in joist hangers from fascia beam to side beam. However have decided this verandah to use a ridge beam instead. Also I have access to a mates nailgun, but have no experience with one, since have used joist hangers all the time for rafter to beam connections.
My queries are:
1. As i understand a ridge beam essentially is not load bearing but simply holds everything into place as such, what is the recommended size i should use for this ridge beam since rafters are 140*45 and side beams are 190*45. Ridge beam length is 5 metres?
2. If ridge beam is not load bearing, I dont necessarily need a longer post holding up the ridge beam on each side, since have seen some people do this but most have avoided this. simple rafter connections to ridge will essentially hold the ridge beam up?
3. what is a stronger connection - a joist hanger or 3 nail gun hits for the ridge to rafter and rafter to fascia beam connection? (havent used a nailgun before but prefer the clean look of a nail gun)
4.Planning to put a A-frame on each end of the verandah to support the ridge beam, would joist hangers be suitable here since am worried about holding up the long 5 metre beam high up in the air while attaching the rafters.
Any advice and help would be appreciated. Thanx
