OK team I have managed to brace up that end structure that supports my swinging walls. Who would have thought a window at the other end was going to make it harder. I have gone into a explanation of bracing to explain the problem and how I have fixed it.
I haven't got all of the movement out of that end structure but it is much better. It is just a design flaw of having a large open wall.
I was caught off guard by the large window at the opposite end of the house. The window allowed the top and bottom half of the wall to move independently. This is a problem as my bracing is anchored to this wall. I managed to overcome most of this by reinforcing the corner with double studs on the side walls.
There is still a little bit of movement and I have one more trick up my sleeve. I am going to see if I can build a brace to one of those posts into my kitchen cupboards. That is going to be quite tricky because I don't want it visible inside the house. I will come back to that later in the build.
Next steps is to finish off the sliding roof and swinging walls. I am already well under way, and man you are going to want to see these. They look awesome and I can't believe how they are coming together.
Until next time.
Don't hate... educate, and go build cool stuff.

I like the bad jokes almost as much as the videos themselves. I can't believe how quickly this is going. So fun to watch.

@TwoHandsandaTinyHouse 3 года назад

Hahahaa not sure everyone shares your view there ;). The last few weeks has seen so much happen, it's so nice to see it coming together.

A car shock absorber can also be used for bracing to absorb earthquake energy.

@julythird1505 3 года назад

Thank you! There are plenty of videos advising (and showing how) to install bracing, but yours is the first I've come across to actually show what happens if there is no bracing.

@TwoHandsandaTinyHouse 3 года назад

You are welcome July. So glad it helped. Please let me know if there was anything you didn't understand. 😊

Oh wow, thank you Richard. I really appreciate that. One of my principles in sharing this stuff is to "be interesting". I am not trying to make stuff people like, I am just trying to share stuff I think would be cool and want to watch. And I like cool stuff that not everyone is doing. Very grateful for that comment mate :)

Once you have sheeted the roof and if your using ply for your ceiling that too will help stop your racking. Also incorporating your internal walls or built in structures to be additional support.Love your efforts keep the uploads coming.

@TwoHandsandaTinyHouse 3 года назад

Thank you Chris. I was just talking to a mate yesterday who was saying the same. The one thing I wasn't sure about is the flex in the corners of that end wall as that is what is holding it square and there won't be any cladding/lining. But I had another suggestion of making the window structural, like they do on vehicles. Glass has a huge resistance force so would easily brace it. But I am definitely going to look at using the cabinetry to sure it up. I think that along with the cladding and lining will have it sorted. Thank you for following along Chris :)

@angelpena234 2 года назад

so I don't know much about building, but what comes to mind as a possible solution is using cabinets as a way to strengthen the structure even more... like an arch

@TwoHandsandaTinyHouse 2 года назад

Certainly it is possible and this is how many caravans do it. But my cabinets will designed more around the cabinets I want to create as opposed to structural elements. That would have required something going almost full height and I wanted to avoid that. However, the cabinets will certainly help strengthen the structure.

@racdad Год назад

This is fantastic - clear and thorough. I'm ready to order my strapping and, while I've found this type of metal strapping easily, I can't find anything resembling the tensioners you're using. Any tips on that front???

@TwoHandsandaTinyHouse Год назад

Strap tensioners are pretty common. You should be able to ask at your hardware store for "metal strap tensioners" I'd be shocked if you can't find them. Else, you could make some out of steels angle and a bolt. That's essentially all they are. But a lot of messing around 🤣

@racdad Год назад

@@TwoHandsandaTinyHouse Thank you so much for answering so quickly. Sorry for the delay! Welp, once I got the hardware stores to understand what I meant by "metal strap tensioners" they couldn't find them in their stock - or on order. Ah well. Looks like I'll go for the steel angle > cut to strap width > drill 3/8" hole through angle & strap (making sure the angle is pointed inward) > pass a bolt through with washers and a nut > e voila! Did I miss anything? Are there particular washers I should go for?

@72Dexter72Manley72 3 года назад

Great progress.. I like the metal strap bracing. I haven't seen that done in a trailer before. 🕵🏽🕵🏽👍🏽 Do you think you may have to make that rear window opening a little smaller, to help minimize the movement ?.

@TwoHandsandaTinyHouse 3 года назад

Yeah strap bracing is a great light weight option for bracing. Very common in building. It's not the best option in all situations and it's why I have had to combine it with brace board but it does work well. No I am not going to bother. I should have shown a shot post bracing up the corners. It has taken heaps of movement out. There is still some there. Instead what I am going to focus on is trying to incorporate a corner brace up closer to the opening. Even if I brace the rear wall better it will still be limited by bracing system on the roof. That and well... I think the window is going to look pimp haha. Something to consider if I do it again though. Certainly compounded the problem.

@zacdredge3859 3 года назад

OSB and ply are pretty much treated interchangeably in terms of bracing capacity. The main determining factor with any sheet bracing is the fixings as you already emphasised... unless you use plaster; please nobody use plaster in a moveable dwelling. As for this build and the issue you're having I think it primarily relates to the shallow angle of the bracing that runs full length. It may seem counterintuitive but if you really think of the structure as a system then the simple solution is to layer additional cross bracing at the angle that your smaller sections are; so put extra cross bracing that spans the trusses that currently don't have any(so your X's will end up making a series of parallel lines). That tightens up the whole roof structure and the forces transition without simply pulling on the rear wall directly. Cross bracing loses efficiency the further it deviates from 45 degrees and as a general rule of thumb shouldn't go past either 30 or 60 degrees. Which is why I'd say additional bracing along the roof but at tighter angles than the full-length brace should give the desired outcome and do so at less weight than bolstering the surrounding framework. So if you do it now it will be even stronger, haha. Australian Standard 1684 is the prescriptive timber stud framing document nationally for anyone who's curious. They include calculations, tables and diagrams to figure out the bracing requirements(typically measured in KiloNewtons of wind force relative to the area formed by the top half of the wall face plus another calculation for the roof). For a mobile tiny you want to assume at least 100km wind speed given you can legally drive that fast(ie don't just design for your local wind intensity and forget cars go bloody quick) but even then you may end up traveling 80-90km/h into a headwind at some point so I'd just over-engineer anyway. Also try to incorporate aerodynamics at the design phase. You've seen horse floats and caravans so the concept isn't foreign it's just that working with curves is tricky and those aren't quaint cottages, but even working with angles a hip roof is more aerodynamic than a gable. There was some talk about Aus Standards being free to the public through the Library of Australia but I just checked and guess this fell through. Can still find most of the info through commentaries, excerpts and product specifications that reference them. I'm lucky to still have them from access through uni but don't think I am permitted to distribute.

@TwoHandsandaTinyHouse 3 года назад

Thank you for the detailed information. Really appreciate you sharing it on the channel. I think ply actually has a higher kN rating but both certainly better than just strap. I actually think plaster could be used in a tiny house providing you work in the appropriate movement and willing to patch some cracks when you setup. At the end of the day tiny houses are designed more as moveable houses than traveling accommodation. Unless that is what you are building. I could do more bracing but I am not sure it would get much better with only one partially braced wall actually bracing my side walls. The shallow angles certainly made it hard but the additional bracing (the extra squares) really helped lock it up and running closer to 45 degrees. But I am also doing a ply roof which will add to the kN rating overall. It has always bothered me that we are governed by standards that you cannot freely access. That is just ridiculous. But I also understand they need to fund a standards body to adjudicate and maintain them.

@zacdredge3859 3 года назад

@@TwoHandsandaTinyHouse Yeah, I think they should at least make stuff like framing, footings, masonry etc available. Maybe they still will but I wouldn't hold my breath. I thought ply was higher too but I checked and saw mixed information. It's definitely more stable though, whereas I think osb is really only strong under longitudinal force. I'm sure your measures were enough in the end, just thought I'd share a simple solution for any attempting their own build(which probably won't be as complicated as yours to be fair). I'm planning to do this sort of thing with a bit of a different roof frame, I can't really explain in a comment how it goes together though haha. The thing is to allow for plaster you probably need to brace internally with ply anyway, and then you're adding unnecessary weight. Then I just prefer ply in the first place; looks nice IMO and you can still paint it if you want.

@unboundlearners519 3 года назад

Hi, wondering what metal strapping you're using? Looking to use this type of framing for a small 10x14 board and batten structure. Thanks.

@TwoHandsandaTinyHouse 3 года назад

This is a perforated metal strap. It's about 1mm think and 25mm wide so 1” and a bit over 1/32 thick. Not sure if it's common over the but I imagine you might have metal strap bracing of some description. Doesn't have to be perforated but it's easier to use with tensioners.

@llikwodash 3 года назад

What about using hardwood brace ply? It’s like 4mm thick and is an Australian standard for cyclone arenas?

@TwoHandsandaTinyHouse 3 года назад

Great suggestion. And had one of the higher ratings I think? Only reason I didn't was weight and I couldn't get any nearby by the sheet. Steel strap helped heaps and I'll have a ply roof which will add to the kN rating. But I certainly coveted l corrected l considered it

@Sildenafil_Damages_Eye_Retina 2 года назад

Hello

@rob1971 3 года назад

Another really informative video. I'm curious as to why you use nails and not screws for attaching the bracing? Oh, and maybe stick to the building, rather than the jokes, stud 😉

@TwoHandsandaTinyHouse 3 года назад

Thank you Rob. That is a great question and I was wondering if it would come up. I can't proclaim to know the exact answer (so if you are reading this and have a better one, please add) but here is what I understand. Screws are too brittle. To take the twisting force applied to a screw when it is driven they need to be quite hard. If it was too malleable the shank could twist under a heavy drive. The problem with this is it makes them brittle (by comparison, this is all relative). A bracing nail is going to take a lot changing forces. Being pulled sideways, force up on the head and shock loads. Screws are not so good with these kinds of forces. This could lead to failure. A bracing nail by comparison is strong but slightly malleable. So when they get a sideways shock load they are likely to bend a little into the timber as opposed to have the head pop off. I can tell you by having to remove a couple when I put bracing in the wrong spot. I got the cold chisel onto the head of the nail. It didn't take the head off. Instead it painfully dragged the nail out of the timber. The nail came out intact, bent but intact. I hope that explains it. Haha and yeah, I'll stick to building I think ;)

@rob1971 3 года назад

@@TwoHandsandaTinyHouse That's a great explanation, and I can definitely see the logic to it. My brother is a timber engineer, so I'll need to ask him and see what fixing method he'd normally use - in their case I think it's often glue due to the products they're manufacturing though and then bolts for combining components. Haha, it's good to add a little humour from time to time 😉

Two Trailer!? What happened to the definition of "tiny" ha good on you though

@TwoHandsandaTinyHouse 2 года назад

My friend I don't disagree with you at all. Ironically I am put off by huge tiny houses. In fact I get a lot of people contacting me about how big they can build and my response is to start as small as possible then evaluate what is important to you and only add as you find decide is important to the life you want. I am doing two trailers for a couple reasons. 1. In Australia the only way I can tow it without a truck is to keep the trailer small. I want to be able to move myself with only a 4WD. 2. I work from home and I spend long hours at a computer. I wanted to create a space that was healthy to do that but I could also create a mental seperation from a place I can relax. That meant a "study" of sorts which is very hard to fit in to a tiny house and still have a lounge etc 3. I wanted to stay true to the idea of a "tiny house on wheels". So many people are building massive tiny houses that end up on foundations and you'll never move then. At what point does it become a transportable house. I think this has important implications for regulation in Australia where people can start to hang axles off of a tiny subfloor and call anything a tiny house. You can guess what regulators will start to do there. I wanted my tiny house to be able to be hooked up and moved in a day. It's a true road registered and road safe house. Noting I have some challenges with my openings to overcome. 4. The biggest reason. I wanted the challenge. I've never seen a fully mobile two trailer tiny house that is one seamless house done. But it's talked about a lot. That it my kind of crazy and the sheer engineering challenge to make that happen is something that excites me. So I somewhat agree with you. But my goal has never been to build as big as I can and never will be. Mine looks quite big, and is, but a fifth of the space only exists when the trailers join. It doesn't actually exist in either of the trailers (which I think is cool). Each trailer loses one wall to the join, which actually impacts usable space. And one of the trailers probably has about 1m of luxury space. But I don't subscribe to the idea of "being more tiny" than the next guy so why not. It meant I could build two identical trailers instead of shortening one. Long explanation but it's a very interesting point and one I ironically mostly agree with you. I hope you follow along. I love critical input and I'm planning some cool stuff for the interior.

@@TwoHandsandaTinyHouse Hey I really appreciate the in depth mental layout of your situation, I don't have any criticism but think this is part of the evolution of rethinking housing as a globe. Like any trend, it starts with filling a niche, and eventually becomes a status show, but that does not discount the ingenuity and creativity that goes on beyond the limelight. I personally have been toying with the idea of modular connecting homes, but I am trying to make a 8x10ft house out of panels that maximizes living space, and reduces weight by using emt conduit, like a greenhouse, or steel studs and panels that can be placed hastily but ratcheted tight, figuring out gasket design to go between the panels that won't let air, moisture, fungus or insects to come in, but is also dependable and has give. As well as roofing that requires no screws because it has ratchets over the top keeping the roofing secure to the quonset style home. This way it can be dismantles loaded and stacked into a 4x6ft bed small truck, and reassembled elsewhere, and have hallways between two which extend the living availability, and allow for not having to heat the both rooms depending on where the tenant is. I think this will give more opporunity to people who don't own hauling trucks or have access to them. Really like your idea, and the technique you are implementing to gain maximum sheer strength with the minimum amount of space consumed.
