Hello forum,
I have a carpentry question.
I want to install a small loft in my garage, which was built three years ago.
For this, I plan to install beams (see picture No. 3) with cross-sections of 70x110mm (2.8x4.3 inches).
On one side, these beams should be attached to the wall plate (picture No. 1) of my garage roof using joist hangers, and on the other side, they will rest on the partition wall with a thickness of 11.5cm (4.5 inches) that was built during the construction (picture No. 2).
The distance between the wall plate and the partition wall is 2m (6.6 feet).
Now I have two questions:
1. Should I mount another beam or a squared timber on the wall as a support to screw the beams onto?
2. How far can my beams extend beyond the wall?
Of course, I understand that heavy loads should only be placed in the area of the wall or towards the wall plate.
Thanks in advance!
