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.
It doesn't matter. It holds the frame legs together so they don't collapse
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!
Ok. Remove it. Get back to me when you need help with the roof collapsing
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.
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.
