I have a nice outbuilding I am retrofiting into my new shop. It has a main part and then two side carports that have no doors. They, however have a concrete floor. The main part of the building is a wood floor. I am planning to frame up the front of the carports and make doors for them. One carport will be my machine room, the other one lumber storage and the middle of the building will be where I setup my workbenches for hand tool work and assembly.
I am not very experienced in carpentry framing so I have a couple questions. First, I am planning to use two 2×4 on edge on either side of the opening. The concrete cinderblock on the left is sticking exactly 3” past the 4×4 post. After I do that, I will make a header out of two 2×10 with 1/2 plywood sandwitched in btw yielding a beam thats 3 1/2” wide which will make it perfectly stand on top of the 2×4 king studs.
It will then be connected to the existing structure by pairs of 2×4’s every 2 feets (see my rough sketch).
first off, the span that this header will have to cover is about 110 +3*2= 116 ”. Is it too long of a span for my beam? or is it ok? After all, its not load bearing ?
Secondly, I will make two doors to close that space. They work out to be 56 ” wide by 72 ” tall. ( i will leave 1/8” up top and 3/8” at the bottom for clearance).
I am planning to make these doors with 1×6’s and 2×4’s to reinforce. I suspect they will be heavy.
I do not want these doors to tear up my framing because of their weight. I am putting a 2×6 backed by 2×4’s behind it on either side to use that as the door jambs. Is that going to be strong enough to support these doors If I use three strong utility hinges?
