Shed floor joist spacing? - Screwfix Community Forum
Guest. Jul 16, 2015. #1. Hi one and all, I'm currently drawing up the plans for a shed I'm going to be building, and I'd like a second (or more) opinion on what the the spacing should be for the floor joists? The shed in question will be 5.4m x 2.3m with 47mm x 75mm timber for the joists and 11mm OSB for the floor itself. Thanks.
wide floor joist spacing - JLC-Online Forums
2005年4月6日 · Re: wide floor joist spacing It appears the building is 26' wide with 13' joists bearing on the exterior walls and a central beam. The second floor room 13' wide. So it appears the knee walls bear at the center of the joists. (Depending on how one does the math) The knee walls transfer about 1/2 the roof load to the center of the joist.
Bracing for floor joists - Screwfix Community Forum
2004年1月7日 · If the span of your joists is less than 2.5m then you don't need to include any noggins. Up to 4.5m span one row of noggins at mid span is needed. Above 4.5m span use two rows of noggins at third points. Noggins need to be at least 38mm wide and the depth should be at least 0.75 times depth of joists. The info you have provided indicates that ...

300mm joist spacing - Screwfix Community Forum
2020年4月19日 · Greentram said: Old building inspector's [imperial] rule of thumb for floor joist spans is safe span in feet = 2 x depth (ins) - 2, thus 200x50 (8x2) will span 4.2m/14ft, 50x131 about 8'4"/2.5m. For floor joists deflection is generally critical: joist stiffness is proportional to I, breadth x depth cubed/12.
24" OC Floor framing? - JLC-Online Forums
2005年10月11日 · When you walk across the floor you can't tell where the trusses are. So I don't personally have a problem with 24" O.C. spacing. As long as the floor members are designed correctly it should be fine. My only reservation is with tile floors. As I understand, 24" O.C. framing isn't recommended for tile.
Long floor joist span - JLC-Online Forums
2000年10月16日 · The joists will span the distance safely, but the span tables are based on "maximum allowable deflection". That is usually 1" per 360", or in your case, about 3/4". That means you will feel anybody walking across the floor, and furniture may rattle. Visit someone with floors that span 22'-28' and see for yourself.
19 3/8 o.c. - JLC-Online Forums
2002年1月3日 · At this rate you save one joist every 8' over that of 16" o.c. without going to 24" o.c. I am framing an apartment building right now that has 24'-4" floor trusses 24" o.c. and 30' floor trusses that are 19.2" o.c. This was done so that we could achieve the same floor stiffness without having to make the floor trusses taller on the entire floor
Subflooring and Joist Spacing - JLC-Online Forums
2001年6月5日 · Re: Subflooring and Joist Spacing The tile industry caqlls for joist spacing of 16-inches maximum for good reason: tiles installed over joists spaced further apart fail on a regular basis. To my knowledge, no backer board manufacturer specifies a layer of 30-pound felt paper between the backerboard and substrate.
