What is really evident from the video is the amount of technical thought goes into this type of building work. Very impressive. I wish I could find builders of this calibre. Yesterday the boiler installer had to come back to correct the condensate waste pipe. He had put the lengths extending in the horizontal plane mostly level and in one area inclined in the wrong direction i.e. uphill. I had to refer him to the minimums set out in the installation guide and also to get confirmation from the boiler manufacturer that if not corrected the guarantee would be invalid. This is my constant experience. I have to find out how the job is done and then check that the tradesman does it correctly. It is clear from your video how much skill and knowledge is required in building. I wish all builders were as capable.

I'm a building inspector (20 years now) and love I flitch beams, so much more flexible to use and handle for the builder, as well as very strong. In loft conversions, a design I used to recommend quite a bit was laying a 12 x 4 under the original purlin (usually a 9 x 3). As the work was in the loft the builder would knock a hole in the gable to get the beam in. If it had to be cut because of the proximity of the neighbouring house then the cut would be at the end of the beam where the bending moment was least. Lay the beam directly under the purlin and sheath with 3/4" to a 1" ply depending on the scenario and screw fix with stepped staggered joints. You could park a bloody bus on those beams! Beauty is you can then fix joist hangers straight off the face. Make access pockets at the ends, again at the least bending moment and you are cooking on gas! 😀

@michaelmewis4761
@michaelmewis4761 2 жыл бұрын
@@SkillBuilder I don't have an issue with the position of the steel plate, it looked good to me. It's good to see the parallel bolt holes at the end and then the staggered fixings along the length, normally @ 16" (400mm) centres. With the flitch at the base of the timbers the steel takes the loading directly from the point of support and not the timber (if it were based centrally). The timber is technically not there for support as such but to arrest deflection of the steel and to provide a point of fixing. I love to see them used on projects. He's done a great job and he'd certainly get a final certificate from me!

@@leehaelters6182 That is a good point Lee. Dependent on the load I would say yes, although in my experience flitch beams are specified by engineers where the loads are not so intense, e.g. in this case, to carry domestic floor loadings in which case a concrete pad stone would suffice. A spreader plate would be good if you could get one in without putting the beam out of level. Another method for distributing the load on a wall is to place a 'Spanlite' over the masonry so that the loading is spread 'over' rather than being a point load In essence it's like making a point load into a UDL.

I (and TRADA) recommend placing the flitch plate mid-depth. This allows for timber shrinkage top and bottom without plate protruding. The plate should ideally be at least 20mm less than timber height. Bearing is not an issue as there should be 2 or more bolts at each end (as James had in his sample) which are to transfer the load out of the plate into the timbers sides so they can do all the bearing.

@@pyrrhical3423 Well... 1) I've never seen a flitch beam made from 2x4s, usually min. 145mm deep in my experience. 2) I'm not sure what you mean by 'shrinkage under load doesnt occur in the compression face'? Shrinkage occurs tangential to growth rings due to moisture loss, which has nothing to do with forces in the beam. 3) the 20mm is for a variety of reasons - shrinkage allowance is one of them, but it also gives some tolerance for plate being a bit off center, timbers being crowned and allows some depth for planing if needed to level up floor. 4) if the plate protrudes and that is what is bearing then, if it's bearing onto timber, chances are the concentration of force on the narrow plate will exceed the capacity of the timber it sits on and locally crush it until the timbers end up in contact again. 5) Why do you think flitches are over designed? Mine are usually designed to be just in. They have to have a factor of safety and often it is deflection criteria that dictates their size. In terms of efficiency, a flitch plate is the most structurally inefficient use of steel - ideally the majority of the steel should be at the extremities of the beam, i.e. like an i-beam. Flitch plates can often end up heavier than an equivalent steel beam that would do the job. Sometimes the trade off is worth it for other practical reasons such as being able to support a flitch beam off hangers, ease of adjustment of length on site, ability to nail hangers onto the side etc.

I could probably fit a steel plate if required, but didn’t know whether it would be necessary when only carrying a domestic floor.

Are you saying that a flitch beam can replace an RSJ without having to increase the designed section size (or not significantly increase it)? I can see how the steel plate is still the ‘web’ but are the adjacent timbers now the ‘flanges’? I hope I’ve made sense. I had a situation where lack of space and a large RSJ could have been made significantly easier if I’d been able to ‘make-up’ my own beam. Thanks 👍

I haven't seen of a Flitched beam like this, since I was an apprentice in the Eighties. Then it was 9"x 2 1/2" timbers with steel in-between to match existing lintels at windows in a preservation zone in London. We then had to add a special paste, administered by a specialist company, so we were only aloud back after some weeks, this paste was placed between steel and wood to stop we were told the reaction to each both other when placed together. I've never come across it since and wondered why when we clamp on timber to RSJ's all the time and saw little difference. As it wasn't used more, I put it down to being Just frowned upon. There's been loads of occasions when this would have worked for me. Thanks for the Vid 👍

Just out of interest the difference between universal beams and rolled steel joist is the section. RSJs have much thicker flanges with a steeper angle (about 5 deg) whereas UCs have almost parallel flanges. In reply to a previous comment I will say that if you take a building inspectors advice on structures make sure your insurance is up because if it falls down the council will take no responsibilty for it. Building inspectors are only there to make sure that the building complies with the approved plans.

You really need an engineer to pontificate on this, but I've little faith in modern ones with their computers. Total inability to resolve the forces on a hip is just one thing amongst others. Maybe I'm old fashioned but I look at the amount of timber in this roof and I wonder why they don't carve it out of a solid block!! I was brought up on the likes of McKay's carpentry.

A question for James, if you don’t mind me asking! Where did you get the socket for your Impact driver? I can only find up to 10mm in a 1/4 hex inch drive - and most coach bolts need a 17mm. Or is it a regular socket plus an adaptor? I wasn’t sure how one of those adaptor bits you see on Amazon / eBay (1/4 inch hex to 3/8 or 1/2 inch square) would hold up… so am on the hunt for a proper impact rated socket bit in the right size. I’ve got 50 coach bolts to do soon and has reigned myself to using a ratchet, as it’s not worth a Milwaukee impact wrench for so little!

Good video, for the timber and steel flitches you should use toothed washers to distribute the load into the timber to act as one and transfer load more effectively ,.. generally 5d edge distance for bolts in timber.. Hope this helps

Neil Thanks for your advice. When bolting two timber beams together a toothed washer helps. When you are bolting steel to timber there is nothing to get your teeth into on the steel side. Hope this helps.

Whilst you're right that single sided tooth plates increase bolt resistance in timber, I've never found them to be necessary when calculating a flitch beam, so 1} I don't think it's worth creating the extra hassle for the installer to procure (single sided tooth plates are not as widely available as double sided ones) and fit (getting them to press in fully can be a pain, even when large washers are used),and 2) it risks creating the situation where they are not fitted and so the beam as installed becomes under designed. So better in theory, but not in practice - at least in typical domestic scenarios.

@@smartbuildengineering A toothed washer being bigger helps distribute the shear from the smaller circumference of the bolt as it reaches the edge of the timber and thus reduces potential splitting. ..

Hi there. Not on topic for this video, however I have watched and sympathised with the video you did a while ago about the good and bad concerning heat pumps.

Hi David I know that I have been critcised by some of those other channels and it is all part of what happens if you stick your head above the parapet. I am fairly certain that I would not change the minds of any of them because they all make a living from installing heat pumps. I am sure they all have their hearts in the right place and when I do talk to them it is surprising how much common ground there is. If we go down the intended route of taking out gas boilers and replacing them with heat pumps it will do that industry a lot of harm because heat pumps will get a very bad name. I am doing them a favour if they only knew it. The short term gain from the grant will destablise their market and make it harder for them in the future.
