How to Reinforce Ceiling Joists to Handle Heavy Loads
In addition, I would add another 2x6 under the existing 2x6 and use adhesive to sister onto the 2x12 but also under the existing 2x6. In this situation, I would use double 2x joist hangers at each end of the joists. You will need to shim under the double …
Deck Joist Span Chart - Fine Homebuilding
Decks get wet and may be framed with incised treated lumber so spans may have to be adjusted. Until a few years ago, the IRC didn’t have deck joist span tables. But the 2015 IRC included a new one (Table R507.5) that will make it easy for deck builders to spec a joist size for a given span and joist spacing.
How to Calculate Deck Cantilevers - Fine Homebuilding
Needless to say, there’s a lot more to joists than simply choosing the right lumber. But that’s still the best place to start. Dried lumber makes building easier. Most decks are framed with pressure-treated dimensional lumber. The pressure-treating process leaves lumber wet; the moisture content may exceed 50%.

doubled 2x6 joist span - Fine Homebuilding
2005年12月13日 · Ditto, with a properly sized beam down the middle doubled 2X6's should be fine. However , instead of sistering and worrying about properly connecting, they seem to still be adequate @ 8" o.c. (HF #2), basically dropping one in between, given 3/4" glued & …
The Right Header for Every Wall - Fine Homebuilding
Engineered-lumber manufacturers provide header-span tables similar to the ones listed in the IRC, making it easy to size them. I’ve used engineered lumber as single-ply headers, multi-ply headers, and rim-board headers. In many cases, the engineered-lumber members can span greater distances compared to sawn-lumber headers of similar sizes.
How Far Can a Deck Beam Span? - Fine Homebuilding
Deck builders can now refer to Section R507.6 Deck Beams and Table R507.6 Deck Beam Span Lengths to determine the size of 2-ply and 3-ply built-up beams made from 2×6 through 2×12 lumber. These values didn’t change in the 2018 version of the IRC. (For more on other aspects of framing an elevated deck, have a look at this guide.)
Dimensional shrinkage of pressure treated lumber.
2019年12月3日 · I’m building a deck to an existing elevation using 2 x 8 pressure treated lumber. It measures 7 1/2″ and the wood has a moisture content that ranges anywhere from 30% to 50% on these new boards with an average rating of near 35%. The small town home center said that the lumber was kiln dried before treatment.
Drying Wet Framing Lumber - Fine Homebuilding
There are 4 tools you can use to dry your wet framing lumber. Time, Air movement, De-humidification, and Heat. 1. Time. Given enough time (assuming it’s not getting wet again) that wet lumber will naturally dry. If the outdoor temps are above 60 degrees F then it won’t take much time. Maybe 3-5 weeks to get from 18% down to 14%.
