Posi joist metalwork

[TEO]

It took a long time, but I finally found a sheet that details all the dimensions of standard bar joist's.
when I get back to my desk, I'll try to dig it up, and scan it.
Normal Hot rolled angles, hot rolled round rod.

Thank you that'd be v useful

Anyone any ideas where to get the metalwork for these open web timber joists please?

Thank you, excellent site.

Sign up and see if you can purchase them.
I did find this under that heading:
"FIND YOUR NEAREST MITEK® MANUFACTURER
With the largest network of licensed fabricators across the UK and Ireland, you are never too far from a Posi-Joist manufacturer.

All manufacturers use the very latest BIM compliant MiTek 3D Design and Engineering software and are able to provide clear and detailed drawings."

Sign up and see if you can purchase them.

I found them via Google and in the search result, it shows some pricing:



But a three figure number in pounds starting with a '9' means you are not going to be able to buy a dozen pieces.

Yup, I think they come by the thousand

...and you probably have to jump thru a bunch of hoops (and pay allot of money)
to be a licensed user.

Brilliant, that really is very useful

You don't even have to make zig-zag rods, I have seen people just make "Vees" put the bend at the bottom.

 

[Agroshield]

You don't even have to make zig-zag rods,

Making the zig zag might be more efficient if you are starting from a stock 10' length of round bar as you do not need to cut it up into small bits. However, to do that you do need a lot of space around your bending machine with a long length.

Somewhere or other there is a similar design guide for angle iron trusses and rebar trusses. It is in the area of 'alternative' or 'developing' technology publications.

I did the long bar, made a bender, used 20' lengths.
And I'm advising as someone who has actually, wait for it, "done it"
it's easier to saw and bend.
You perchance ?

you would be better making your own up

angle iron for the beam 3mm 1 1/2 "
a flat plate that is shaped / strengthend

you can use a hydraulic press to do so as well instead of a bead former

 

[pod70]

What exactly are you using the beams for?
I've worked in the roof truss & floor joist industry for years and wouldn't fancy making these up myself without the correct design software (there's more to these than meets the eye), a hydraulic press and suitable bench with jigs.

there not really that much just formed pieces of metal with strengthened parts done by a former with 1mm steel

....and here I thought this was a welding forum.....what was I thinking......

No software needed, nor hydraulic press's.
follow the charts I posted.
Simple common hot rolled shapes, cut to length.

Maybe I beams would be easier to home make? Presume you'd router a slot in the top and bottom chord then cut 12mm OSB into strips the required height and glue and clamp together?

Yup, go out and get yourself some run of the mill OSB, a router, some pine boards and get going.....
Because everyone knows that's all there is to makin' em....

Well obviously not everyone knows that's all there is to making them! And In my defence I did say "maybe". Perhaps you can enlighten everyone on the process then it can be ruled in or out and we'll all know for future reference instead of making smug comments at 2 o clock in the morning.
