Here is a case where investing in a post frame building kit from people who have actually constructed buildings is a huge asset (am surmising this is not the case, since this person sent the Hansen Pole Buildings Technical Support email address a plea for help).
Reader James writes: “I have a 24 x 60 pole barn. I pulled my outside dimensions from outside of skirt board now on my trusses are an inch and a half long on each side how can I fix this?”
Dear James ~
Since I do not know who supplied your post frame building kit package, I will have to do some guessing as to how your post frame building was designed. Typically questions like this can be answered by whomever provided your plans and materials – and if it is an engineered building, the building engineer should be consulted as well.
A quick solve for anywhere in the country and any method of construction – to the eave outside of all corner and sidewall columns, attach a pressure preservative treated 2×6 from grade, up to the level of the trusses. In most cases two 10d galvanized common nails spaced every nine inches will be an adequate connection. As these 2×6 will be in contact with the ground, they should probably be treated to at least a UC-4B standard. Your building’s skirt board and any other exterior mounted framing can now be attached to the face of these 2×6. Using this method allows for siding to be installed normally, without any undue compensations to get it to lay out properly.
Another possibility – provided the heel plates of the prefabricated light gauge metal connector plated trusses are not in the way, you could cut 1-1/2″ off of the end of each truss, making them 29’9″ to match the width of your building from outside of column, to outside of column. In no case cut through a steel truss plate.
Or, (in cases with recessed or joist hung purlins) attach the eave girts between the overhanging 1-1/2″ of each truss. The end connections end up being a bit trickier here as it requires nailing through the end of the truss, into the end grain of the eave girt.
With stacked purlins, the eave girt can be nailed to the outside face of the columns above the truss.
If the chosen path is any of the last three choices, when the endwall steel is placed, start the first panel of steel 3/4 inch PAST the corner of the building. The corner trim will cover this and it eliminates having to do a lengthwise rip on the last sheet of steel on the opposite corner.
