Splice stringers

[RL1]

Hi, I need to splice 2 pieces of 7-step vangstycken from a balcony approximately 2.2 m, please don't suggest building my own as I need a simpler solution😫

Glue and screw a sufficiently coarse board on the inside of the stringers? Barely makes it easier, but a little at least 😊

Tail them together, a so-called dovetail joint??

Can you maybe screw an entire length of a support beam on the outside of the stringers? If so, which screw should I use?

 

[topmount]

Maybe not the cheapest solution, but if you want such a long staircase and want to maintain the open feel, you can overlap the vagnstyken on the inside.

Glue and screw a sufficiently thick rule on the inside of the stringers? Barely makes it simpler but a little at least 😊

As long as possible without going through. I would also glue. But very important that it is properly dimensioned both with the wood and the number/positions of the screws. Too many screws, as well as too few, weaken the construction. Seek help in some way if you're not comfortable with it. It can be dangerous if a staircase breaks...

I'm thinking of a 45*145 rule.

How many screws and which screws? Thinking of beams 45*170

 

[FredrikR]

45x145 or 170? 😉

170 on the outer sides and 120 in the middle (because that rule must go below the steps

6x80 screws, a suitable number. None side by side along the grain direction. It's possible there is a guide on screw joints on Svenskt trä.

6x80 screws, a reasonable amount. None next to each other along the grain direction. It's possible that there's some guide on screw joints at Svenskt trä.

Do you mean French wood screw?

Or do you mean träskruv c4?

Yes, a wood screw for outdoor use.
