Ceiling Strength to Support Chin Up Bar
About to mount a chin up bar on the ceiling in the garage. Total weight on this bar could be as much as 300 lbs. Got up in the attic to look at the spacing of the ceiling joists and they are 1.5 x 6 inches and 24 inches apart. The joists span the width of the 2 1/2 car garage without any other joists that would criss cross them to add support. There are 2 very long 2 x 4 tie ins criss crossing the joists and nailed to the tops of the joists but they don't look like it provides any real support. Not sure what their purpose is. As you might can tell, I have very limited knowledge of construction techniques. Are the joists strong enough to support the weight mentioned?
Thanks,
Barry

What does the span measure? Notice "ceiling joists, 2x6, 24"o.c. here: http://www.colonie.org/forms/building/bdspanab.pdf

Ceiling joist spans in middle column, 4th one down, 2x6 - 24" on center---maximum span: 10'6" with a 10# load. Yours are over-spanned for just a 10# per square foot drywall load and 5# dead load. They will not support you. I would use 2-2x8x19' in the ceiling, nailed together w. 16d nails every16" on center, and mount the bar from that.

Thanks Gary. I noticed that when I go into the attic that I can put all my weight on one of the joists without any sag. The brackets on the chin bar will bolt on to 2 separate joists thus sharing the load. Would this make a difference? Was my garage ceiling built incorrectly?

Once upon a time we had porch swings. They were hooked to screw hooks in the overhead ceiling joist. Ceiling joists back then were often 2X4s. The swings sometimes held three people. I can't ever remember an accident. Are we maybe over thinking this?
