Read the thread. It is NOT a fundamental rule.

Google "hanbjälke" and read about its function. Return afterwards
 
But it's not a hanbjälke.

Oh no? And what is it then?

Look closer at the picture. The lower beam does not continue into the wall on the left. In other words, it has no load-bearing function.

It doesn't matter. It holds the frame legs together so they don't splay out.
 
No, it is not mounted to carry a load. It is just hanging.

Thank you for all the discussion! I read all the posts but still have trouble understanding why the horizontal rule is considered to bear some form of load by some of you.

As you can see in the picture, it is only connected via a few nails to the angle rule that supports the outer roof.

Ok. Remove it. Get back to me when you need help with the roof having collapsed in.

To my knowledge, tie beams are usually attached to both legs of the roof truss. According to the pictures, the horizontal "beam" is attached to a vertical beam/stud. That would mean ALL the load would fall on the right angle and the joint of these two beams. It is a very weak construction as the load wants to open up the right angle formed by the joint of the two beams. I would install a proper tie beam and then dismantle this peculiar construction if it needs to be removed.

Edit: tie beams are called [hanabann] here in Skåne. But I think they're called tie beams or collar beams. Correct me if I'm wrong.
 
"The collar beam is the lowest horizontal part of the roof truss."

"Between the principal rafters is a collar beam whose function is to reduce moment in the rafters. The collar beam can also function as a tension member if the horizontal anchorage in the floor or walls is insufficient."

That is, the beam we are talking about IS a collar beam. Its function is not to support the roof but to either reduce moment (torque) or pull the walls together. Both of these functions could exist in the TS even if principal rafters are cut off/missing. Whether there is overcapacity in another construction and the beam can still be removed is another question!

What do you mean? Why would the roof collapse?
The beam isn't attached to the house on one end and only with two nails on the other end of the roof beam.

A collar tie does not bear the weight of the roof. It holds together the roof truss and prevents the walls from spreading out.

Google roof truss and read about its function and parts. Or tear it down and keep your fingers crossed.

Terrible how you're going at it, look at the picture and read the text carefully, it's an extension where one leg of the roof truss has been extended.

Close-up of a roof extension showing a rafter's shortened tie beam not reaching the old exterior wall. Wood structure and ceiling elements visible.
Here I have zoomed in on the "hanbjälke," it ends before it reaches the old exterior wall...

If the horizontal rule is not attached to something that supports or pulls, it's just a matter of taking it down.
It is there solely for you to be able to attach a ceiling.
