rafter legs.
For large spans, you will need to install additional elements yourself to reinforce the load-bearing beams and increase their load-bearing capacity:
rafter legs (struts);
racks;
runs;
sleepers;
contractions.
All elements are made of first or second grade greece mobile database wood. To choose the most suitable material, you need to pay attention to the following points:
felling site (it is better to choose northern regions);
time of felling (a tree cut in late winter – early spring will be stronger).
Calculation of the system
Before you start assembling the structure with your own hands, you need to make calculations and correctly select the cross-section of all elements.
Roofing is a responsible process in which mistakes cannot be made.
Depending on the width of the building and the required cross-section of the rafter leg for the designed span, a design solution for the rafter system is selected.
Calculation of the length of rafter legs
