Hello PrepHole,
I nned some advice on the best way to combine multiple wooden beams.
Would you choose option A and put screws in a 45° angle through both beams, or
option B place an angle connector on top or rather
option C and put the angle connector underneath the beam?
How strong does it have to be?
Option C is basically how shelves mount to walls and is the best out of the options you list, but you'd have to find a shelf support that works for the load you're trying to support.
If this is supposed to be a structural connection (more than simply mounting a shelf), then none of these are appropriate.
How would you connect them if it's supposed to be a structural connection?
I would redesign and support the cross-beam from below
First of all,thanks for the answers so far.
I guess I have to provide further details so it becomes clear what I'm trying to do.
I want to add insulation to my outer walls. The structure I provided in my picture will be repeated many times containing exactly this kind of joint.
The load itself should not become too heavy - the weight of the structure itself + the weight of the insulation + the cobering in form of roughly 1-2 inch of plaster.
A support from below is a valid idea, but basically is the same as Option C, just with a bigger angle connector
Those solutions are not really applicable in my opinion since for decks the force will be distributed differently than in what purpose I have in mind.
The most stable configuration would of course be a bolt going through both beams of wood inside my walls, but that would be very counterproductive for insulation purposes.
> I want to add insulation to my outer walls
You mean the inside of the outer walls right? And the gray beams in
are already present?
Definitely don’t go with a thousand angle brackets, just put two long screws straight in each crossing.
You could frame an actual faux wall if you add additional upright beams and put the horizontal members in between (screwed in from side). Costs more in wood but easier to make and more support
No, it's supposed to be external insulation in the form of wood fibers. A two inch layer of ventilation is planned as well.
What I have in mind is something like pic related, but instead of going with 8 inch thick wood I figured it might be more handy and cost effective to split it up.
put a screw straight through the front one into the back one. jesus man.
>A support from below is a valid idea, but basically is the same as Option C, just with a bigger angle connector
Wrong.
>A support from below is a valid idea, but basically is the same as Option C, just with a bigger angle connector
are you for real?
What will be adequate structurally depends on the sizes and loads involved. That kind of arrangement is not uncommon in deck framing, fwiw the vertical pieces are posts, beams are horizontal.
There are metal connectors that function like c that might work but are usually sized for 2x joists-

Aka "post to beam connectors"-

Here's a whole article with various solutions-

If the parts are large enough to not be weakened by the holes, simply through bolting them can work; lots of pergolas do that...but codes and common sense might restrict that or other solutions.
It's a case by case thing.
Lap joint
Ignore the rest of these lap slappers
option A is pure moronicry
It's actually a valid solution. I didin't pull it out of my ass.
The kind of screws used for this are those in the picture.
sounds like you have your soulution
Dont do A, itll just split the wood.
seems to me no matter what you do you will be relying on screws to hold it together, may as well just go a. Get pan head screws to avoid splitting.
None of those. You through bolt them together.
Sure, that's the most stable configuration. But having a connected piece of metal going from the inside to the outside when you try to do insulation is pretty stupid.
Now if you use a wooden dowel instead it might just work.
on the same note how do you connect a rectangular piece of wood coming in at an angle to another piece like a rafter to ridge
i was thinking one nail near the upper tip and then criss cross near the lower
