It's a little difficult to show it all. The kitchen extension and garage flat roof runs the whole length of the side of the house, the fall of the flat roof also runs from front to back as well. The height of the flat roof prevents a warm roof as its too near a window on the landing. The only...

Eeek that's not good then. I've just done a drawing which hopefully helps. The extension is part of the kitchen and leads to the garage on the side of the house. The timber beam is on the inner leaf and supports both sets of joists and the steel beam on the outer leaf is above the joists of the...

The external leaf as a small galvanised beam sat on top of the extension joints and these joists then sit on the existing timber beam which is under the internal leaf. I'm not sure why it was done that way. I thought maybe it has something to do with air flow from the cavity and cross...

So after looking at the steel beam my SE as specified, I have noticed the depth between the flanges on steel beam is smaller than the actual joists on the 1st floor. The joists are 175mm and the beam which was specified is 178mm however the beam only as 146mm between the flanges so you can't...

Haha thanks, it's good that you can help So my SE sent this over, it's a trada coach screw designer. It will make more sense to you than me but one thing i'm unsure of is the different minimum measurements between my SE and what you've put unless I've misunderstood. '] [/URL] I have done a...

What I forgot to ask is where it has the minimum spacings like Sedge, Send ect. Does the S refer to steel.? So it would require screws to be 40mm from the edge and end of the steel

Thanks again for the help Tony, yep that makes sense the screws being nearer the edge on the steel So the way my SE has drawn the bolt layout as 3 bolts in a straight line unlike your drawing, this would not be possible? Also are the measurements you said based on the center of screw or edge...

I have just had an email back from the SE and like you said, he recommends coach screws as they will be easier to fit than bolts Reading what he said he says it won't matter if you use bolts or coach screws using the existing measurements? As long as it's 800 N/mm2 that's all that matters...

Ok thanks, I'll bring up the coach screws v bolts with the SE What length of coach screw would I require if the combine steel timber is 85mm? I take it you don't need any washer at all with these? Something I'm not sure of is the bolt spacings ect When it says 40mm from the edge, is that...

Thanks Tony, yes there are 3 purlins. There is one on each plane about half way up the roof. I'm not sure putting 9x2 onto the existing 9x3 would work, wouldn't the ends need to be supported on the 9x2? it's already near flush with the brickwork as it is. I'm going to email the SE back and...

The first picture is just the timbers calcs being used in the loft. The other 5 pictures are the steel for the front timber beam

Actually in Hazel Grove, Stockport. I take it you've come across this or something similar before? Are you an SE or builder?

Hi Tony The way the load bearing walls run in the house is odd. Basically where you would have two separate steel beams across a spine wall, I can only use 1 steel beam that's nearer the rear of the property as the load bearing wall runs straight down in a line at the point. The front part of...

Yes the bay window is at the front. No dormer.

Yeah a new floor is going in the loft so all timber lintels need reinforcement. The front bedroom is the only one I can see which is causing an issue as it's got the rafters resting on it also as well as one end being in the cavity

I've got 3 timber lintels that need 10mm steel plates bolting to them. 2 of them seem straightforward as they are not built into the cavity. However the front bedroom one which is 3m long sits below the ceiling with the rafters resting on it to the bay window. Now one end is built into the party...

Mainly for storage but I want to put a server stack up there with cctv recorder ect. Seeing as every bedroom as cracking down the centre of the ceiling the existing joists can't take a single person up there let alone any storage.

Ah ok thank you Yes usually you would have two steel beams, one wall that's bearing the roof is about 30cm offset from the ground floor wall and is sat across the joists in the living room. The SE said it could cause cracking to the ceiling but he said he would need to run the calculations...

I want to put a stronger floor in the loft. At the moment the joists in the loft are only 75x50 with the joints running from front to back of the property. Now I have had a structural engineer around and he said he would have to calculate the new floor as a proper floor because of the spans...
