Hi guys and gals,
I've been watching the forum for some time and have gleaned a lot of useful infomation. This is my first post and have some question that I'm sure you can help me with.
I am building a deck. This is my second deck. I recently transformed my upper storey deck from tiles to timber as you can see in the photos. I also got rid of that hideous balustrade and went with the stainless steel wire. It looks great and really opened up the view.
My second deck is to be built as a free standing deck in the middle of the back yard. I haven't done exact measurements yet but it is approx 6m x 7m and will predominantly be a rectangle with cutoff corners at one end (bit like the shape of a boat).
The plan is to have bearers mounted directly to stirrups with the stirrups imbedded in concrete. The deck height will require one step, so perhaps 500 off the ground. Probably use 450 stirrups.
In looking at the layout I was planning to put in 5 rows of 5 stirrups at 1.5 metre intervals.
I've had a look at the span tables and although I'm good with computers I can't make work out the tables.
Q) where is says 2/90X45 does this mean there are two pieces of wood to make up each bearer?
Q) would I just nail these 2 together and put them into the stirrup?
Q) would having the 2 pieces touching create a water retention problem? Should they be blocked apart?
Q) if I use a single piece of wood e.g. 125x75 I should centre it over the stirrup and use a filler on both sides?
Q) given my 5x5 foundations is 2/90x45 suitable? Am I over the top with foundations?
Q) I'll need to join the bearers to make up the lenght so should I use a scarf joint inside the stirrup? This would only allow one bolt through each end of the bearer, would this be strong enough?
Joists will be 90x45 at 450 centres.
Thanks for all the help you have already given me and for the future.
Cheers,
Malcolm
