Up till now we have been "stick building", kind of taking general measurements on site and cutting to fit as we go...drawing in chalk to size on concrete driveways and parking lots... because I am not very good at working in 2-D. I can't really paint or draw, or make architectural drawings. But FINALLY now that I have been working on designing the roof trusses for months, and not that we are ready to build the roof trusses.. I have finally got the hang of designing things ahead of time, making sure everything will fit, and all the measurements are correct....so. onto th3e roof trusses! I had a dream a few nights ago of two sueful design considerations: one is of the way to make beautiful embroidered curatins, and the otehr is to use wood for the lower cords of the trussed, so they can be exposed, and metal cords above that, to attach, first 18 gauge furring channel, then the roofing material and the interiour paneling on the inside. Anyways, here are the hand drawings for the bathroom/bedroom floor platform, the four different roof trusses we will be making, and the two interior walls that will enclose the master bedroom. The drawings are on a scale of 2":1'
Scott found a program that will design roof trusses for you, and you know how much it costs? $7,000. I asked an architect for help, and they wanted $1,500. YIKES! No wonder I have been working on these drawings for months!
These two drawings/charts are first for the amount of materailw e will need to finish ALL framing, some 1'x 3 5/8 18gauage C-track, 18 gauge studs, 1"x 1 5/8" c-track, and hard wood beams, 1" x 2". The second drawings is a a little sketch od how we are going to attach the trsusses to the tops of the walls. We will enclose the C-track that the wall studs are fastened into with another piece of c-track to make a box, and the on all four sides of the truss and stud we will use 14 gauage angle stock, through bolted across through the truss and the wall stud, and also through the c-track. At four locations, denotedf by spirlas in the last image aboove, the through bolts will be tubular, hollow through the center, and through the bolts we will thread a piece of steel wire, which will be fastened diagonally across the 2' span between the wall studs, fatened at the floor. This will provide diagonal stability for the roof, to with-stand wind sheer and also to diagonally brace the walls.
