    Default Joining Bearers

    Hi just after some help please.

    I am building a back deck and the bearers are 100 x 75 and span 9600.

    They are detailed to be supported on an enaged pier at each end, then directly on galvanised stirrups (the bolt to footing type 200mm leg to suit 75mm) for the intermediate supports. How should I join the bearers to span the 9600?

    Is a scarf joint in the stirrup ok?

    Thanks

    It would depend on the stirrups you are using, i.e. where the holes are for bolting. If they are in the middle i would probably use a vertical half lap join, making sure the full width of each end of the bearer is supported on the stirrup by at least 20 mm. Assuming a 90mm stirrup this would leave 50 mm for the half lap and bolting through.

    If the holes allow for a simple butt join, i would do that.

    Thanks for that.
