About Regular Hip Rafter with Jack Rafter with Lip cut par rembarrement
I have been through this blog and reproduced the diagram (and the angles!) successfully.
I can thoroughly endorse this way of getting to know how it all works.
For those wanting also to do this, here are the basic parameters:
Profile/Jack rafter slope: 52°; eave angle 90°
giving:
Hip rafter slope: 42.15°
Hip rafter backing angle: 33.86°
Jack rafter:
- coupe alignement: 31.62°
- coupe aplomb: 38.00°
- coupe lip: 19.38°
These values agree when:
- measured on a printout of Michel's document: RegHipJackwLipRembarrement.pdf,
- measured on the SketchUp drawing that I made,
- calculated using Sim Ayer's Android app "Rafter Tools".
I went a step further and produced a "rolled-out" version of the cuts at the head of the jack rafter:
I put this information here to encourage other Apprendre la Charpente blog readers to do the same.
Any feedback would be interesting ! Michel is doing a great job.
