门廊基础设计和施工
我正在建房子，在一个凸起的板坯基础上缠绕着门廊。
简单的矩形52'x40'。
2×6 @ 24 oc外墙，带拉链护套和壁孔纤维素。
板坯将使用块铺设杆墙体24英寸等级。块是在NC中所做的方式而不是倾倒似乎。板坯将像这样绝缘......//m.etiketa4.com/app/uploads/2019/03/slab3-700×998.jpg.
桁架屋顶，我可以将门廊屋顶整合到桁架包装中。
What is the best way to build the porch foundation? Wood framed and open underneath the porch or build a raised slab for the porch as well? Aesthetically, I like the look of it being open underneath with stone or brick columns and lattice type panels in between (see attached pic). Considering the insulation detail and the thinner “shoe block” at the top of the stem wall, can I still attach a ledger board at that point on the stem wall to wood fram the porch? Or is the thinner block at the top a problem? In regards to building an additional raised slab for the porch, this would mean building a stem wall, back-filling it, and pouring the slab on top. This would completely encase the main stem wall of the foundation in back-fill, soil, dirt, etc…to the point where it could not be visually inspected for termites. Termites are an issue here. Is this a problem or am I over thinking this?

Jason,
我会把你的帖子放在凹凸。FWIW，我觉得倾倒凸起的板块只是为了支持门廊将涉及很多不必要的费用。
史蒂夫，
Thanks for the reply. One of the things I'm wondering about is the cost of each method and which is more economical, but mainly I'm wondering about the ledger board attachment considering the thinner concrete at the top of the stem wall.
P.S. - It appears that we're climate zone neighbors. :)
嗨杰森。
I am just a homeowner with a passion for green building. So keep that in mind. Frame construction is likely to be your most cost-effective option. I’ll let one of the professionals comment on the ledger board issue.

史蒂夫，
我当然很感激输入。我也只是一个喜欢尽可能涉及的房主。
I should have mentioned the total size of the house. It's a 52' x 40' rectangle. So it will be a fairly large porch since it will cover a 52' side and a 40' side and be about 7' to 8' deep. With that in mind, I've gotten some contradicting info on which would actually be the most cost effective way to do it. Hence my reason for posting the question here, along with question on the potential ledger board issue. I'm sure the slab being raised plays a significant factor. Perhaps one of the professional builders will comment on this.
Anyone else have any thoughts or input on this?
Jason, I like raised slabs for conditioned space, and have designed the same for porches as well. So far I have always gotten strong pushback from contractors; they say it's too expensive to fill and compact the sub-slab area. Either way can work; I would suggest pricing it out both ways and see for yourself which makes more sense.
If you're concerned with attaching the ledger in a stick-framed floor, you could set the whole porch on piers, including the end closest to the house. Helical metal piers make this especially easy.
迈克尔，
谢谢你的建议。我对分类帐的担忧并不是一个附着在棍子框架地板上，而是挡板基础墙的较薄顶部。我正在附上我计划的绝缘板细节的形象。分类帐将靠在基础墙壁顶部的较薄“鞋块”上，并将通过刚性泡沫代替混凝土来支撑，因为它不会没有板坯绝缘。我不知道杆壁的较薄部分是否为分类帐创造了结构问题。我想的结构工程师的好问题。
On different note, would, or have you had any concerns in the past regarding termites in a situation with the raised slab for the porch as well considering you cannot visually inspect the foundation any longer with it being completely "encased." See my second attached imaged with a raised slab for the porch. The red circled area can no longer be inspected and termites seen before they have a chance to cause major damage. Perhaps I'm concerned about a non-issue? Overthinking is major weakness of mine...
再次感谢您的输入。这是真诚的欣赏。
杰森，对不起，我的意思是“为”棍子框架的地板 - 你的门廊。如果它倒入混凝土，我将没有关于连接到厚度厚度的阀杆墙壁的担忧。我没有经验与块墙一起做的，但我将更舒适地连接到填充的细胞。或制作门廊楼。
关于白蚁的好问题。我们在这里没有他们，所以我不考虑它们很多，虽然我经常常规盾牌是安全的。也许包括金属闪烁，让墙壁和板坯留出来？
我同意Michael的锚定墙壁中的开放核心。您可以将嵌入块的螺栓嵌入块和核心填充前3个课程，并使其成为坚实的连接。让他们放置在正确的位置需要一些计划，但房子的其余部分也是如此。我认为框架门廊比用具体更便宜，但也许你所在地区的价格更有利。如果您使用混凝土门廊，您可以有一个暴露的聚合完成来拥有不同的东西。与砖墙一起看砖墙，你可以让泥瓦在岗位位置放置一块砖砌窗台，并将普通砖放在那些地方。或者让它们在岗位位置撞出墙壁，并安装薄砖块以获得您的外观。
