![]() ![]() ![]() Could put a double floor joist right there though. No glulam and I cannot put that much weight on the interior wall end, as no direct post/wall underneath. Since I have to build another roof on top of it, would the live load be double? I don't know where that's available right at the moment though or price point Prefer to run the ceiling parallel with the house walls, but I guess that's possible with 2' DF on 4' oc. I cannot figure out how to change spacing unless I got the wrong link, but I looked at 3 of them Does that solve it or do you want to keep going with the above? That looks good, is readily available and pretty fast to dry in. half of each rafter is bearing on the eave wall, half is bearing on the ridge x 30 psf=540 lbs per lineal foot on the ridge. Sounds like a 20' span? 18' tributary width. The easiest way to do a cathedral ceiling is a structural ridgebeam with rafters hanging from it. I'll let you walk through the rafter check, talk me through it like I did above and I'll spot you. 6' opening with 12x12 rc df & 3' opening with 9x9 rc df no floor joists above it. The floor joists would rest on the horizontal beam. Fastening the stud to the vertical beam and 'now' only down low to the horizontal beam. Was planning on overhang the horizontal beam 3 " on each side. Scroll through that and think about what they are showing, good stuff for post and beam or timberframe builders. That is shown in pics in the second link in my post above. If I put the pin at the top of the beam and into the post, as the beam shrinks it will lift off the notch and hang from the bolt. If I put the bolt or peg through the beam into the post down low on the beam, close to the notch the beam will bear on the notch as it shrinks. Same thing if you bolt a horizontal beam to a notched post. That is shown in pics in the second link in my post above. Scroll through that and think about what they are showing, good stuff for post and beam or timberframe builders. If I put the bolt or peg through the beam into the post down low on the beam, close to the notch the beam will bear on the notch as it shrinks. Same thing if you bolt a horizontal beam to a notched post. As the post shrinks the far side will move towards the point of attachment, the angle clip. If I bolt a piece of angle iron to the floor on the door jamb side of the post and bolt the upright leg of the angle to the post, as the post shrinks the door jamb side of the post will not move. Whoops, we're on top of each other but I'll post the reply to the post Q and then read this latest post. Worst come to worst we could build a "pole barn" type RC truss, but really do not like the look all that much. I can build pretty much anything metal and can work with wood, but am not a timber finisher by any means. With all that, we are not 'married' to any single idea, but we are trying to do something different without getting too exotic though. 20'圆" c-channel with 24"x12"x1/4" plates welded to both ends and either 1/2 chain with a threaded eye bolt for tension bolted through and to the exterior wall with a plate on the exterior side and/or to the end of the rafter heel or 2"x2" sq tubing welded under the c-channel to the outside wall plate and/or to the rafter heel If 32" oc doesn't work, could do something like this on 24" oc. Would need to still have a piece of rough cut on top of metal truss for ceiling to attache too though. Was thinking of something like this, with the 3x12 piggy backing the metal truss on truss 2, 4 & 6 or replacing 2, 4 & 6 entirely. This could be made up on the interior wall side of the house a few different ways, so for now lets say 7 rafters. I am wondering if 3x12's work on 32" oc.ģ2" oc would be 7 rafters plus a half. Don, on the exterior roof system you had said 2x12's work on 24" oc. ![]() ![]() We would prefer to have the 6" t&g pine or the 8" t&g hardwood as the ceiling vs rocking it. Of course by doing that, it requires another roof to be built on top of it, so we can achieve R38 insulating value. The idea is to have a cathedral ceiling with exposed rafters preferred. Don, while you're replying on the door/archway posts I thought I'd post on the interior stuff & anyone else with idea's, please chime in ![]()
