How to safely mount w/o gussets

I’m in Australia so I need to mount this upside down (with the angle supports on top). But seriously, the only wall I can put this that has a high enough ceiling also has a door that opens directly into it and would hit the gussets/angle supports.

I need a bracket that either has the supports on top of not at all. Not having any luck with google, just getting bookshelf brackets and $500 heavy machinery specific brackets

Not keen to just put the brackets upside down in case the welds let go and it brains me

我在澳大利亚，所以我需要将其倒置安装（角度支撑在顶部）。但说真的，我能放置的唯一一堵具有足够高天花板的墙也有一扇直接打开的门，会撞到角撑板/角支撑。

我需要一个顶部没有支撑的支架。谷歌没有任何运气，只是得到了书架支架和 500 美元的重型机械专用支架

不热衷于将支架倒置，以防焊缝松脱，这让我很头疼

Steel still work upside down.

钢铁仍然可以倒置工作。

The engineered weight loading doesn’t

It goes from the weight being pushed into the wall and the welds compressing to being pulled out of the wall and the welds being pulled apart

设计的重量负载不

它从重量被推入墙壁并且焊缝压缩到被拉出墙壁并且焊缝被拉开

eyeballing it the angle is say in the middle (its not) of the horizontal.

the force on the wall plate at the horizontal is user weight acting upwards.

say the angle bar is 45 degrees (its not) the load along the bar is user weight / sin 45 = user weight / 2 in compression.

anyway i cant be bothered doing any more maths but the point is that it has fucking nothing to do with the welds, the problem is the mounting hole above the horizontal bar, the torque at the top is pulling away from the wall and into the wall at the bottom regardless of orientation.

in op pic the distance between the bottom angle and the top mounting hole is large, pull out force on this fixing is reduced. mounted upside down, the distance between top hole at the wall fixing and the load point on the mounting face (angle bar) is minimised and so pull out force at this fixing is maximized.

the most simple solution is to remove the door if temporary, or rehang the hinges if permanent to open away from the bracket in stead of towards.

目视它的角度是在水平线的中间（不是）。

壁板上水平方向的力是用户重力向上作用的力。

假设角杆为 45 度（事实并非如此），沿杆的负载为用户重量 / sin 45 = 用户重量 / 2 压缩状态。

无论如何，我懒得做更多的数学，但重点是它与焊接无关，问题是单杠上方的安装孔，顶部的扭矩从墙壁拉离墙壁并进入底部的墙壁，无论方向如何。

在上图中，底部角钢和顶部安装孔之间的距离较大，该固定件上的拔出力减小。倒置安装时，墙壁固定件的顶部孔与安装面（角钢）上的负载点之间的距离最小，因此该固定件的拉拔力最大。

最简单的解决方案是，如果是临时的，则将门拆下；如果是永久性的，则重新挂上铰链，使其远离支架而不是朝向支架打开。

It won't be the welds that fail. Also the thing isn't engineered to the point where someone gave thought to the nature of stress at the welds. They just did it 'plenty good' and tested it.

Since you'll have reaction forces for every force and torque is a force the length of the lever arms will make a difference and kangaroo land mounting will put half of the bolts in a slightly more disadvantaged position as it would have been otherwise.

This difference is insignificant and if the safety margin in final product is anywhere near that difference it's unsafe to begin with. Just bolt it to the wall and it will hold two people, upside down or not.

aussieland is a drywall country

in that case you're probably fucked anyways and better treat your home like a raw egg

不会是焊接失败。而且，这个东西的设计还没有达到有人考虑焊缝处应力性质的程度。他们只是做得“非常好”并进行了测试。

由于每个力都会产生反作用力，而扭矩是一个力，杠杆臂的长度会产生影响，袋鼠式陆地安装会将一半的螺栓置于稍微不利的位置，否则会出现这种情况。

这种差异是微不足道的，如果最终产品的安全裕度接近该差异，那么从一开始就是不安全的。只需将其用螺栓固定在墙上，无论倒置与否，它都可以容纳两个人。

澳大利亚是一个干墙国家

那样的话你可能就完蛋了，最好像对待生鸡蛋一样对待你的家

>>3003978

okay but what is it? what does it do?

>>3003978

好吧，但这是什么？它有什么作用？

You're not going to break that thing, but you could bolt the shit out of it if you're afraid it'll go. Put brackets where the welds are.

>>3003990

It's a pullup bar.

你不会破坏那东西，但如果你担心它会掉下来，你可以把它拧出来。将支架放在焊缝处。

>>3003990

这是一个引体向上杆。

>the only wall I can put this that has a high enough ceiling

Are you a hobbit? Put it into.a different wall, bend your knees

>>3003978

>我能放置的唯一一堵天花板足够高的墙

你是霍比特人吗？把它放到另一面墙上，弯曲你的膝盖

>Welds pull apart

That is the least of your worry compares to tiny fastener getting detached from weak frame.

>>3003981

>焊缝拉开

与微小的紧固件从脆弱的框架上脱落相比，这是您最不需要担心的。

>door that opens directly into it

isn't that the point?

>>3003978

>直接打开的门

这不是重点吗？

Thanks for the info guys

Yes it’s a gyrock wall with 450mm gaps between studs (the bar is 1200mm wide) so I’m gonna put a hardwood backing board across 3 studs and attach it to that

I’ll look at drilling some better placed holes on the mounting plate to reduce the pull out force

I have std 2400mm ceilings and I’m normal height so I can touch it without jumping. Mounting it on a 2400 wall would be way too low. I have one small room with raked ceilings and dormer windows and an inconvenient door thats perpendicular and flush to the wall that I can’t remove or rehang. But I’ll make it work

谢谢你们的信息

是的，这是一面 gyrock 墙，螺柱之间有 450 毫米的间隙（杆宽 1200 毫米），所以我要在 3 个螺柱上放一块硬木背板，然后将其固定在上面

我将考虑在安装板上钻一些位置更好的孔，以减少拉出力

我的天花板标准为 2400 毫米，而且我的身高正常，所以我可以触摸它而不会跳起来。将其安装在 2400 墙上太低了。我有一间小房间，有倾斜的天花板和老虎窗，还有一扇不方便的门，它与墙壁垂直且齐平，我无法拆除或重新悬挂。但我会让它发挥作用

how much of a weighted pullup is safe for the welds? Can I store spare plates on this? I'd like to see the calculations.

>>3003987

>>3003988

多大的负重上拉对于焊缝来说是安全的？我可以在上面存放备用盘子吗？我想看看计算结果。

>>3003978

Attach outside ends to ceiling, no need for angle supports.

>>3003978

将外侧端固定在天花板上，无需角度支撑。

>>3004046

Yes sand no. That's fine if the door opens outwards like in your pic, but if the door opens inward, the angle bracket only allows the door to open to 90 degrees.

>>3004046

是的，沙子，没有。如果门像您的图片那样向外打开，那没问题，但如果门向内打开，则角支架仅允许门打开到 90 度。

>>3004097

Bad faith argument.

It's not a rack for you to store plates on it's obviously a pull up bar.

>weighted pullups

Yes it's safe. There's a limit to weighted pullups, most guys can't even and wont ever add their own body weight.

>Calculations

No one has the data on this. Welds are - as I have explained you imbecile - done by feel and not a fabrication sheet. And do it yourself you insufferable fag, why would anyone else?

>>3004097

恶意论证。

它不是一个供您存放盘子的架子，它显然是一个上拉杆。

>负重引体向上

是的，它很安全。负重引体向上是有极限的，大多数人甚至不能也不会增加自己的体重。

>计算

没有人有这方面的数据。焊接——正如我向你解释的那样愚蠢——是凭感觉而不是加工板完成的。自己做，你这令人难以忍受的基佬，为什么要别人做呢？

>>3004132

Just say you don't know, it's easy.

>>3004132

就说你不知道吧，很简单。
