Super Zimmerer 2012 Task Model

Aufgabe 1 Dachausmittlung from the Super Zimerer website
Task Model 1 Roof Design

Here's a link to the Super Zimmerer's website with other task models.

This task model is all about roof design. Your given a ground plan and you have to draw the unequal pitched hip roof out geometrically.


 The roof profile slope angles are 50° and 40° with eave angles on 2 of the corners of the ground plan that are not at 90°. In this next drawing I drew out the roof design without the ± 1.00 , that represents raised or lowered plate lines to make sure I understood the basic roof design of the ground plan. The g1 & g2 dimensions are developed from the profile of the roof slopes using the same rise dimension h. The rise dimension h can be any dimension, but it's best to made it about 1/3 of the total rise of the roof for clarity. When your drawing parallel lines from the eave line using the g1 & g2 dimensions you want to keep them away from the ridge lines for clarity. The intersections of the  g1 & g2 dimensions locate the hip rafter run lines.


It's best to separate the different areas of the roof  to draw out the cripple hip rafters  that are developed by extending the lines of the eave lines. 


Here's the completed drawing for the roof design without using the ± 1.00 , that represents raised or lowered plate lines.
