Hi everyone,
maybe someone here can give me one or even several good tips.
The roofing over our cellar entrance is to be redone or "refurbished."
Current status: roofing with multiwall sheets on longitudinal beams (80x80) attached to the house wall with joist hangers.
Current size approx. 4x2 m (see photos for the rest).
I would now like to put new supporting beams into the joist hangers (again 80x80 to continue using the hangers).
The new beams should be about 3.60 m long > at the end, a 10x10 crossbeam is planned on 3 10x10 support beams (see photo > H-anchors are already in place).
The width of the roof should be 5.40 m (on the left and right, one joist hanger each will be added. That is the plan for the supporting framework. For the 80x80, I would use rough-sawn construction timber (unfortunately, I cannot find planed beams in 80x80 in the required length).
For the covering, I would lay trapezoidal sheets (6 sheets at 1.05 x 3.65 each) (for support, the short crossbeams will be placed again between the longitudinal beams).
The longitudinal beams thus rest on 3 points: 1. joist hanger - 2. middle post - 3. 10x10 crossbeam.
I know it is not the usual construction, but would it be "justifiable" like this – or doomed to collapse? I would like to avoid a ledger on the house wall due to the existing joist hangers.
Do the 80x80 longitudinal beams carry load the same way as an 80x60 beam – or is there already a veto here?
I hope I haven’t forgotten anything so far....
Looking forward to any constructive feedback here.
Many thanks & regards
