Hi guys, been a bit busy with the project, I've been a lot more involved in it than I thought I would be, but I just wanted to stop by and say thanks for everyones help. I'd like to especially acknowledge @Brad93 who messaged me to help out. I would have had no doubt he would have come through...
Yeah, I was reading the deflection limit of the plate welded underneath it, oops :doh:
No. Kane is absolutely correct. The RHS is specified for resistance to torsional effects which is important in this case. There will be brickwork on the outer leaf supported by a welded steel plate causing...
Great piece of advice! Yes, the bi-folds will be the last thing to go in once all the dead loads have been applied. I think I quoted the wrong value in one of my previous posts; the SE calculated deflection is 16.9mm for the ~6m length (L/360).
I've already set the opening height to be ~20mm...
Update: Found a good local mobile welder with 40 years experience who is confident he can fix it. He said it was no problem, he showed me his certifications, pictures of previous jobs, he told me how he would do it and he even showed me what he would use as well as all his other kit in the van...
Yep- well spotted! He said he would get this welded on before putting the beam in because I pointed it out to him. Not sure if he did it though as I wasn't there for that bit unfortunately. Another reason I want to get it fully welded now.
Spoke to the SE and a fully welded connection should be fine and they will recalculate. Could have still used the hollo bolts but I don't trust the welded connections from the shop now and would rather just get it all done properly.
Then spoke to the builder yesterday and when he started...
It is on the ground floor. I calculated the weight and its about 463kg with the plate, columns and beam. Add a little extra for the baseplates. So it would need either a crane, a couple of genie lifts or brains to get it up :laughing:
I did suggest a forklift too as there is access, but he said...
You are absolutely correct. There has already been some back and forth with the SE on other things, but the original design should have been followed in this case.
I'll definitely be stopping work on this part. I will go back to the SE and see if they can specify a welded connection here as I...
Yes, it's a steel and brick built extension. There is going to be a new roof over the existing conservatory as well, but that steelwork hasn't gone in yet. Didn't want any brickwork returns hence the 150x100mm columns flush in the walls. There will only be a flat roof on top, so not much load...
Thanks for chiming in so quickly guys, it gives me the confirmation I was after. The connection detail was designed by a structural engineer, the builder twisted my arm and said he can cut it, slot it in from the top and then weld it in, so hesitantly I said yes to it as long as he is 100%...
Hi guys, just joined the forum because I'm in need of some urgent advice. Having some building work done which involves a steel goal post for some bifold doors. The beam is a 6m long box section (200x100x10mm) which connects to the posts which are 150x100x5mm. A 80x160mm box section was welded...
