Full Log King Truss Tie Beam notch at full log walls?

[Neil Stasilli]

:confused: What is the best notch for bottom of full log king truss tie beam at full log walls? Any lay out ideas available? Really stumped. All Ideas welcome.

I don't know what a king truss is, so IDK.

as a rule we do not notch anything, so I am at a loss... most notching is done with a scribe.

Peter, a king truss is a triangle that supports the roof and the free span from wall to wall is engineered into the construction of the truss so you need no posts to support the truss. They can be made of full logs, heavy timber etc. Neil

Neil,

I recognize you from another log house forum, so I know you already know this, but I'd like to explain it for any newcomers to the industry. LHBA members generally use a ridgepole that is supported by vertical logs or timbers that rest on the foundation. It is a simple, yet elegant system that is pretty much foolproof if the walls are stacked in the LHBA style.

With many other forms of wall log construction, (including the style you are using Neil) the wall logs settle as they cure and the roof must be supported, either by the walls, or on upright supports that incorporate some mechanism that allows for vertical adjustment as the walls settle. Typically that mechanism is a screw jack at the base of every vertical support in the structure.

The LHBA system of log wall building ends up with a wall that does not get noticeably shorter as the logs shrink. Consequently we can get away with using that simply elegant system of uprights supporting a ridgepole for our roofs. Due to the simplicity of the LHBA roof, it is tough to find many of us who have put much time and effort into log or timber trusses. We don't, for the most part, learn anything about notches for the King or Queen posts because we mostly don't employ those notches in our method of building.

That said, there are a few notch and timber frame guys/gals who occasionally hop on this forum and maybe they'll chime in. I just thought I'd explain to you again, and everyone else out there why this post probably won't generate a ton of response from us. Kinda like asking a Unimog question on a Honda motorcycle forum. I like 'em both and I might read both forums but I wouldn't expect a great answer about one of them on the other forum.



PS... Only done it once myself but we used what one of the guys called a butterfly cut notch on the bottom of a King Post in a house we did for a movie. He was just some ole worn out movie carpenter so don't know if the terminology was correct but it was kinda fun and it seemed to work OK. Personally I'll never notch another log structure and I can't imagine the roof on the home we are building being supported any other way... But that's just me.

I guess you don't understand nor looked at any pictures of our work.

I'll make this simple, real simple. Log trusses, king trusses and others are complex assemblies that need engineering, steel, bolts and the like. We don't do complex. I have one notch in my home and I screwed that up. Its ugly and no one will ever see it again.

We use ridge poles, not trusses. I suggest you google log trusses. I did and found several video's and many company's that want to show their stuff...

We recommend a large overhangs that trusses generally do not support.

Good luck

Note: Log King trusses are triangle of logs that generally flattened on the roof side that have internal structures that support the span.

Thank you, I know we have shaired ideas before. I am supporting the ridge poles with adjusters on the up right supports. I thought a nonfunctional King Truss in the living room and dinning area would be a nice touch in our home. Thank you very much for staying in touch and conferming my choice of construction is the best choice for me. Here from you again.

[Neil Stasilli]

Thanks for the come back on my confusion. I am trying to keep it simple as I can. Winter has been long and my mind is going 1000 miles a second. Good to here from you all on my issues. Here from you soon.

If its non load bearing why not just choose the style you like the looks of? Here is a king truss we made for an entry way into a commercial building, I'm not a fan of the brackets but its easy and its what the customer wanted

You can skip the notching and use lags

Or spend the time and make pretty notches

Thank you and all the LHBA members that replyed to my thread. I get the picture. I have a plan. Thanks again. Neil
