The upstairs corridor wall wasn't something I really thought about until it's nearly time to do it. Then I thought thats a lot of wall for a slab to hold. I know weight transfers down at 45 degrees, so I suppose a lot will get transfered to beams but still. There's a baby beam only 1.5 m away...

Yes the hydrogen rod was indeed too big for the welder. Couldn't get them in the smaller size, no demand for them I guess. Maybe they are only used on big structures like ships over here. Literally nobody around here had a decent wattage welder, tried all the welding shops and self hire. Didn't...

I have asked already but they're all on religious holiday in Bali right now so waiting for reply. Also im pretty sure they'll say its fine as they designed it but I'd like a second opinion from a developed country. The way it is here is there is little responsibility or recourse. If something...

Hi guys. Just questioning a couple of things on our house designs. We have a brick wall on the upstairs floor that forms a corridor to the bedrooms. It's 4.5m high so quite substantial weight and is largely just being supported by the floor slab which is 12cm thick 2 layer x 10mm wire...

Cool thanks for the advice. I'll do fillet welds. Yes my research also led me to preheat to about 200. Google AI is pretty good on the subject. I think my 420 grade rebar is counted as low carbon and 150 would suffice as minimum temp. Difficult to get exact info so will probably run with 200 to...

Might have found a solution thanks to Stevie888. I can buy low hydrogen welding sticks online and my builder says he can weld them. I know the welding process (presumably even lower hydrogen) will weaken the steel at least a little so was thinking just hedge my bets and weld half of the short...

Thanks thats helpful to know. To give you some specifics yes all the steel is the same, just bad photo probably sorry. All 16mm 420 grade rebar which is the best available here. There's 2 lower graded than that. Beams designed for tension with additional bars in centre bottom and top 1/4 into...

Its not really about UK standards. All western standards would include a large safety margin. Exactly how much i dont know. Here in Indonesia there are no standards or codes we need to work to for permits. This is purely for my peace of mind. Most builders here never even use 16mm rebar...

I had thought about that as wouldn't be difficult, but that column is choca with rebar. 2 beams connect to it at 90 degrees. Each beam has 4 x 16mm top rebars with hooks, then 3 extra 16mm bars about 5cm below them for added shear resistance. Not going to be able to drill 18-20mm holes without...

Thanks but what i am saying is there isn't 500mm, thats the problem. I read overlap should actually be 40 to 50 x diameter depending on which source I was reading. So minimum 64cm. If you look at the photo all the rebar in the middle are short, one is only 20cm and the others range up to 45cm...

Hi guys. I'm new here just looking for some help please. Hopefully asking in the right place. I'm english but building in Indonesia. Our builders have messed up a bit on house build and left the rebar short for splicing to new column on one column. We have 12 columns and the rest are OK. 16mm...
