You should gain good concepts rather than us guessing and every location has different ideas for wind and snow load. This site might offer you so,e real numbers and real plans that have stood the test of time. I'm just saying, plan well, think to the future! 12 foot sounds good and should work nice, but think it through. End up bending wagons, cracking building supports. If you use angled bracing at top to support a weaker header, you lose some width up top just where the kicker flair is. Most kicker wagons are flaired at the top, making them close to 10 feet wide actually?Ī 12 foot span makes an 11.5 foot opening at best. Is this plywood going to overload the roof? I'd like to put plywood sheeting on top of the joists and then a metal or shingle roof - 3-12 or 4-12 pitch. What about roof joist board sizes and what spacing? No intermediate posts between the front and back down the 20 ft run or do I need to support that in the middle too? If 20 ft deep, 2 x 12 header, single - would that suffice, or do I need two, one on each side of the poles? So when you have a header going the length, say 12 ft centers on the bays and 4 of them, 48 ft total header length. Wagons are kicker wagons, 8ft wide, square bales of hay. I've got 3 2x12s with two layers of valley tin for a header on the sidewall of an old barn. If you doubled or tripled 2x12s and sandwiched valley tin between them it should be a lot stronger.

Has more space to get wagon backed in between posts and some space to walk between loads once in the shed. Lumber used for the plates with 10 and 12 foot spacing of poles will be much less expensive than what is needed for 16 and 20 foot spacing, also easier to handle during construction. If 5X5, loaded either way, load will be slightly over 10 feet wide. If 4X5 loaded on round side, load will again be slightly over 8 wide. You could set poles 10 feet, but again still close. If 4X4 rounds, loads will be a little over 8 feet wide regardless of being loaded flat or on round side. You could get by with poles 10 feet on center, but it would be close, as the post and their thickness are such that they will not be 10 feet distance between them. Therefore, if you have 8 foot decks, you could have a near 9 foot wide load. What are widths of the deck of your wagons? Will hay be small squares or large rounds? If small squares, then you will probably have the ends of the bales hanging over the edge of the deck a few inches. Wish you luck and wear a hard hat, 2x4s accidentally falling from high places will kill you. Currently building one with the LVL on 20s.The 2x12s will be extreamly heavy if pre built. Block them together with 6圆s every 4 feet or just use an lvl.

I did one and wish I would have left gable end open instead Posted 07:45 (#6672423 - in reply to #6672131) Subject: RE: Pole Barn Bay Widthġ6 would be very tight opening to back 2 loaded wagons side by side need at least 20. Now, what bay size fits your needs, now and the future? Maybe 16 feet is easy, but 20 foot lets you easily double your effective uses for the building? Etc. Anything is possible with an engineer design and enough header. Posted 07:27 (#6672369 - in reply to #6672131) Subject: RE: Pole Barn Bay Widthġ2 to 16 foot should be easy to engineer, 20-24 is possible with more thought and $$$$. We built an open front shed for machinery. But anything is possible with enough engineering. If you want to stay with plank, probably limited to 16', if you use knee braces. If you go with an engineered joist, you should be able to go to 20'. Hay loaded hay wagons will be parked in each bay.īetween perimeter columns on the front, what is a reasonable, realistic bay width? Pole barn will be made of telephone poles and a 4/12 pitch single slab roof front to rear. Posted 04:34 (#6672131) Subject: Pole Barn Bay WidthĢ0ish ft deep, 4 bays wide.
