Post-Frame Construction Wall Assembly

montypbbc|Posted inEnergy Efficiency and Durabilityon

只想说我真的很感激这个社区,而GBA你们很棒。

我正在设计一个46×46后框架构建的单一故事。屋顶将由桁架组成,中央填充有松散的纤维素的桁架脚跟2'能量鞋跟。Intello Plus将被钉在桁架的底部和5/8 Drywall上。

乳胶油漆5/8干墙

非负载轴承2×6螺柱墙24英寸,中央有5.5英寸的岩石瓦特

Intello Plus固定在贴在平板地板上的柱框架的柱子上,并粘贴到天花板上的Intello Plus,以继续空气屏障。

5.5”石棉垫之间的8对文章中心of the load bearing post frame.

2×6 Girts 24英寸边缘至边缘,彼此之间有1.5英寸的摩擦摩擦。

15lb felt paper

2×3 rainscreen strapping 24″ on center

LP Smartside Lap壁板

我在宾夕法尼亚州东南部5区的温暖一侧。

几个问题。

鉴于我认为我认为它是最简单的地方,因此我可以正确地密封Intello,有人在柱子和girts的第一个冷凝表面上看到蒸气驱动器的任何问题吗?

The metal siding on Pole Barns give them shear strength will the 2×3 rainscreen straps 24′ on center be enough to make up for the metal?

我可能完全缺少所有其他问题吗?

Really appreciate the input!

    montypbbc,

    No continuous surface, no condensing surface of interest. The posts and girths are just like the studs on an exterior wall. That's not where the trouble usually occurs, it's on the interior face of the sheathing. Your wall will dry well enough to remove any small amount of water that has plans to hang around the wood structure and cause mischief.

    I'm sorry I don't know enough about the shear requirements of pole structures to comment usefully on that.

    非常感谢Malcolm。

    有了我阅读/聆听的所有内容,您所说的似乎也是我最有可能的结果,但是也许这里有人会进一步了解。

      montypbbc,

      有了良好的空气密封和雨屏,即使是带有护套的双层墙也没有遇到水分问题。你的更安全。

      如果没有固体护套作为后备,您还可以考虑使用像Tyvek这样的纸牌WRB而不是建造纸。

        很好,我一直在想,在编织WRB上可能是必经之路,并且我认为也会使闪烁和录制的粗糙开口更加容易。

        Thanks Again.

    我同意马尔科姆的观点,您不应该有任何与水分有关的问题。最好是您的WRB密封,但是组装效果很好。至于剪切,我希望比钢壁板和/或绑带更多的支撑。不是每天的风,而是针对100 mph+风事件。您可以使用电缆,Simpson皮带,带鞋支撑或膝盖支撑 - 您不需要全套护套。更多信息在这里:https://codes.iccsafe.org/content/irc2015/chapter-6-wall-construction#irc2015_pt03_pt03_ch06_secr602.10

    I too am designing a similar post frame house. For peace of mind, you could simulate your wall in this tool - it will show the true R value and drying time of the wall:
    https://www.ubakus.com/en/r-value-calculator/

    Regarding the rain screen straps and siding. Doubt that these are enough to substitute for the shear strength of the metal. However, would venture that if you have the structure engineered, the engineer can find other ways of bracing the structure.

    Am planning something similar. We seem to be on the same page with the "Mooney" wall. Climate zone 6 (MN).

    Inside to outside:
    5/8" drywall
    2x4 stud wall with rockwool batts
    1/2" air gap
    Intello膜,完全用胶带密封
    2'的2'中心2x8 girts搭配摇滚瓦特
    Commercial Tyvek or Mento membrane, with butyl tape where metal fasteners go in
    Standard post frame steel, screwed in.

    Trying to answer the question of how well the wall will dry through the small open channels in the wall steel. Believe there might be a way of configuring the Ubakus tool to answer this question.

    关于能量脚跟。我的设计在CAD中绘制。如果您打算将屋顶purlins冲到桁架顶部(带托梁衣架),则在屋檐上没有足够的空间可容纳完整的R60纤维素(〜20英寸)和好风坝(1-2英寸)。桁架顶部边缘的purins会购买更多的空间。该细节在后框架上略有不同,屋顶pur可以阻碍。我已经接近3',以使能量高跟鞋使这个细节清洁。
