How to attach intermediate joist to frame

[vineeththampi01]

Hi All,

I am in the process is building a deck quite close to ground. I have built the perimeter (framing with 47 * 147 timber) with post every 2.4 m roughly. The shape roughly looks like a triangle. I am bit stuck with how to attach intermediate joist to the framing. I am using a joist hanger on one side (The end which is perpendicular to the intermediate joist), but the other end joins the frame at 28 degree angle. Any idea would be more than helpful.

Thanks,

Vineeth

Thanks for all inputs. My initial thought was to use posts every 2.4m / coach screw So for the intermediate joist in picture which is roughly 7m

(Joist hanger) ......2.4m ..... (Post) ......2.4m ..... (Post) ..... (Coach screw)

But wasn't sure if coach bolt will hold, also thought there would be a reason why builders use joist hangers instead of coach screws?

@skyripper I quite like the coach bolt idea with a spade bit. That would give it a good hold.

I did refer some of the joist span calculations and as per building reg and it says it can go upto 3m, but 2.4m sounds quite nominal. I might add some noggins like you said just to be sure

A joint sounds a bit tedious for my skill set, will go with coach bolt option instead
