The beam and joists are unconnected to the floor / ceiling below as the beam is resting on the front wall of the house and a brick load bearing wall at other end

Doing my loft extension; total house width span is around 6400. I have a steel beam in the middle and joists (3m and 3.6m joists) will meet in the middle resting on the beam for support. Is it ok to simply m10 coach bolt the joists on the beam together where they overlap slightly? As opposed to...

No I know but was told by the structural engineer and by bc they’d suffice as they are sitting on single course of bricks anyways

Yeh they’re sitting on concrete bricks (acting as padstones)

I have finally bolted the steel beams together in the loft for our loft conversion, and there is a 6m beam bolted together resting on concrete blocks either end. There is about a 15mm height difference to make the beam level at one end needed. (The beam is probably sagging at the joint where...

Yes you are quite right; I waited over 2 months for the structural engineer to get the splicing diagrams back to me then I got them fabricated, with 3 plate joints for 1 connection and 2 end connection plates for the other connection. Progress has been slow due to work commitments, Christmas...

Connecting universal beam using welded plate connections for loft conversion floor; should the m20 bolts be tightened to a specific torque or do I just tighten them as tight as I can with a socket wrench? Can’t find any info online apart from specific torques in commercial large scale applications

Thanks. Think I’ll buy some rods and cut them down to 110-120mm instead then it will be much cheaper. Think I was overthinking it as it’s not specified on the plans but it does specify they are m16

How far should an m16 stud be inserted into the wall to hold up a trimmer joist? Held in with resin. I'm thinking 190mm studs should do the trick, 50mm thickness for the joist that leaves 140mm in the wall. These =...

Well the good news is we did it with brute force and some rope. Purchased some high tensile rope from screw fix with a payload strength of 160kg, tied 4 lengths to each hole on each beam and me and brother in law hauled each one up, precariously using the ladder rungs as support as we did...

Haha thanks chaps lots of good ideas here. Sure we’ll get it sorted in next few days. Maybe we’ll just have a go brute force with ropes pulling it up. We tried pushing it up yesterday and that was a no go. Health and safety priority. I don’t usually work with steel wood’s my thing so am cautious...

No we’re not; but because of other concerns we have to put these beams in first

That’s a great idea; unfortunately the purlin in the opposite side is a steel beam mind you I could fix a bit of 3x2 diagonally between the purlin and the brick gable wall and use that as a brace. That would have the same effect no?

Because of the nature of the conversion we need the beams then floor joists in first then the stairs. Stairs will be hung off the new joists

That’s a good idea like that. That would help a lot

I know it’s not a lot of weight but it’s very awkward. We have to lift it 3m before it hits the loft hatch then another 2m to clear it with very limited ‘wiggle room’. So it has to go straight up like a giant ‘I’ which is why we struggled yesterday. I’ll look into the ladder/slide method as well...

Haha yeh it’s just me and my dad the edges are super sharp where they’ve been welded so trying to be extra careful. It’s a super tricky tight space to manoeuvre it up. The block and tackle / chain hoist I think should work. Just worried the purlin would take the weight or not

hi all, so am doing a loft conversion and we have to lift 3x 2m steel beams into the loft. I’ve had the 6m beam needed split into 3 sections and fabricated to be bolted together to avoid cranes etc. Each beam is only 50kg but we tried to lift them through the small hatch yesterday and it’s too...

Bump!

I know what you mean about a chamfered beam now that makes sense. What I was thinking is taking some brickwork out at the front of the house and remaking with the padstone on top. It’s very difficult to see because of all the dust and **** but there is a rough course of stone work in front of...
