what is 'an angled cleat connection'

[DIYedboy]

I have to join two 9 x 2 double beams together at 90 degrees to each other using the a.c.c........eeerrrr, what is such a thing?

Good man Him, so, having looked at the pics in that link, I propose to use some 2" angle iron I've got hanging about to bolt the two beams together at a right angle, that won't cause any probs with the regs inspector will it?

 

[Himaginn]

Ask the inspector. They're usually helpful friendly people.
Or ask whoever told you what to do.

It's this just a random bracket or has it actually been specified?

The inspectors are not fond of random.

" 9 x 2 double beams ", lets call these 9" X 4". " together at 90 degrees to each ". So is this a joist running of a trimmer? or of a post? or of a wall plate? or of a lintel?. Look at a conventional fixing system (say for a pair of 6" X 2") then scale it up. Angle irons could easily work, it depends on what you want them to do and how big they are.

Jeez Prince, ..............eeeerrrr............trimmer?.....post?.............not sure what they are!
Hopefully I can explain what I'm doing which may answer your questions. I have a 30's semi, I'm going to extend the side of the house which will make the upstairs third bedroom 6ft wider. The new pitched roof will be extended over this and the existing wall will obviously be knocked out. One of the 'beams' will support the old wall plate that is holding up the existing roof timbers. I can't really imagine what the other beam is gonna do, it will be crossing over to the new side wall, but it is basically in the middle of the new room so can't imagine what it's doing.

Wood, the structural engineer stated on his list of beams that these two wooden jobs need to be connected with a a.c.c.

A proper structural engineer will specify the size and type of all connections. Otherwise how are you to know?

The cheeky funker has relieved me of the problem of having £900 in my bank account, but hasn't mentioned the size of the cleat.

Robbery aside; if it's a piece (or two pieces) of steel angle, it is not good enough for the SE just to leave it at that. In the BS 5268 code for structural use of timber, there are specific spacings for the bolts/screws or whatever in terms of the end- and edge distances. If you go outside these distances, it can compromise the strength of the joint. As the joint will presumably be carrying some not-inconsiderable load, he should specify the fixing detail. If you do this yourself and it fails, he will disclaim responsibility. Get on the phone........

Are you saying a SE charged (sorry, robbed!) you of nine hundred quid to design a simple cleat end joint.

 

[DIYedboy]

No Jeds................he had to design 8 beams (plus these wooden things) for my rear and side extension

 

[jeds]

Phew, that's a relief. Only £450.00 too much.
