How to join a pre-existing wooden beam?

[vanda99]

I have to remove and move a car port post but the beam it supports has a join exactly on top of the post above it. (I doubt there is a through bolt joining the 2 parts of the beam but I suppose having the join on top of the post was a reasonable method when it was first built). Its a 48 x 200 mm beam 

Can anyone recommend a suitable way of joining the 2 parts of the the beam, like some sort of bracket or length of steel with bolt holes that could bolt across the join. The various sorts of brackets i have seen at Bunnings, in the section with rafter hangers and the like seem too light - there are some lengths of solid hot dipped steel but they are less than 300 mm long with only 3 bolt holes with one uselessly in the middle.
Oh similarly there is a rotten section i would like to splint with something suitable

Any thoughts gratefully received

I could be completely wrong mate - but I think @vanda99 is going to extend the carport concrete and as a result the current stirrup under the beam join will be buried. Hence he moved the post/stirrup to the left.

Hi @Noyade 

Thank you for the heads up. I was referring to their proposed second option (you'll see they made a list), but that includes the option of putting posts next to the old one which is option number three. Although the second option states that they will be installing a new stirrup, I was suggesting that if the old stirrup was still in good nick why not re-use it? But having had a second look I realized that my answer was incomplete. I'll modify it as soon as I can. But I also understand your reference to option three which is to relocate the posts.

Thank you!

Eric
