We also need to add 1.5" from the basement slab to the sill = 122.875" total rise <br /> <br /> The actual stairway rise will depend on the height of the landing:<br /> <br /> With 2x6s and 3/4" planks (6.25" total) it will need to be 116.625"<br /> <br /> With 2x8s and 3/4" planks (8" total) it will need to be 114.875"<br /> <br /> <br /> 15 steps of 7-3/4" (the maximum allowed by code) is 116.25"<br /> <br /> 15 steps of 7-5/8" provides 114.375"<br /> <br /> <br /> The landing or the top step can be adjusted to make up the difference<br /> <br /> ==CAD for Stairway with 7 3/4" rise==<br /> [[File:stairs_detail.fcstd]] - Detailed design file - 7.75" rise<br /> <br /> [[File:stairs_simple.fcstd]] - Simple object for merge<br /> <br /> ==CAD for Stairway with a 7 5/8" rise==<br /> [[File:7_625_stairs_detail.fcstd]] - Detailed design file - 7.625" rise<br /> <br /> [[File:7_625_stairs_simple.fcstd]] - Simple object for merge<br /> <br /> [[File:7_625_stairs_example.fcstd]] - Example - SEH2 partial with Stairs<br /> <br /> ==FreeCAD workbench to generate stairs==<br /> [[File:FreeCAD_Stairs_Workbench.zip]]<br /> <br /> (Note: The generated steps need to be rotated 180 degrees for use in SEH2. If you create a simple copy, you can set the placement angle to 180 deg and then adjust the x, y, and z position to position the stairs. x=349.35" and y=186.125" should align them in the stairwell. Adjust z as needed to move them up or down to meet the landing.)</div> </article> </main></body></html>
