You guys that know metal see the world differently than some of us who are most comfortable constructing with wood. I’m really enjoying this thread.
Is this what your describing? That's fairly obvious , I tend to over think things and would prefer to limit welding outside of my shop. I'm not really set up for mobile. If this is as simple as a "clip" is, what are these tek screws and will they self drill? Fastenal for a source?
I only know metal like for truck bumpers or tractor type chit. Too many years in residential construction.
You're on the right track. Make clip length equal to width of top chord. Put clip where the vertical and diagonal members hit the top chord. Joist are designed for a continuous load on top chord and if you put a point load on it it needs to be at a panel point. Tek is a brand name. Fine thread self drilling #14 x 3/4" with hex head. Fastenal will have them but you can get a better price on line.
Nearly 90* a few days ago when pouring Crete, today in this weather I'm feeling like a wuss and throwing in the towel. It's funny how quickly you get either spoiled or "used to" temperatures. I hardly wear gloves in the winter and they've crossed my mind a few times today, heck even my dog is in agreement.
I'll measure this spacing, if this is a "hard" rule for bar joists I may need to re thing lumber sizes.
It takes me about 2 weeks get acclimated to workin in the heat. Can't take enough clothes off to stay cool. I go thru 2 gallon of water a day when it's hot and humid and I'm workin. But when I'm fishin the heat doesn't bother me as much.
Lookin at the pic of joist you should be ok. The 2x4 is spanning 4' and at 2' on center is only carrying 4 sf of roof load. Do you know what code requires for snow load in your area? We are at 30psf and I've only measured 21psf as a worst case. Drifting can build up a huge pile on one side and cause uneven loading which can get you in trouble.
No wonder I'm cold, just drove out back to measure, the truck "says" 45* My panels (the distance between v&diag members coming together is 48", then the distance from the last panel to the bearing point is 8'8". They are just under 26" deep.
....and there's a slight difference in the length of the bearing surface on one end. Not sure if this is important.
Oak is too valuable up here, not like in PA. I'll be cutting Hemlock, it's our Tulip Poplar up here, but maybe a bit stronger. Iirc snow load up here is around 60# and without heat I (and some lifelong locals) think 3/12 will be fine and should shed the snow. The peak is oriented dead north, the direction of one weather normally.
You're ok then cause the diagonals hit in between at 2'. Each place a vertical or diagonal hits the top chord is a strong point.
Not really. Important thing is to get full bearing of the joist bearing surface onto a steel plate on top of wood post. You could do a similar detail of what you did on bottom of post.
