Roof structure question???

[gaz1]

i would use 2 of these one for either side lower

100mm x 225mm Speed Pro Masonry Joist Hanger Galvanised

Speed Pro Masonry Joist Hanger has remarkable strength without the need for a wide top flange. With no welds the Speed Pro Masonry Hanger is the only single piece masonry joist hanger with a straight top flange. It also has the key advantage that any standard Speed Pro Masonry hanger can be...

then i could wedge the beam thats going to sit onto it before inserting it under the beam

then i would cross memeber the beam to under the old one so its pushing it upward but also supporting by crossways also pushing the joist hanger into the wall

that hanger gives wall support but also gives bolting access ino the wall giving further stability by bracing and also supporting

By the look of the pitch and thickness of the rafters that purlin is doing very little supporting, I'd leave it alone.

Identical roof construction to my bungalow...that's been a 1950,s botch by the builders, you be amazed at what i see in roof spaces by builders of the 60,s and 70,s also...that timber should be in the wall

My bungalow roof is an embarrassment, 30 years old, looks like it was thrown together from whatever off cuts of 2x3 timber was laying around the site.

That's a pretty substantial roof, looks like 4x6 timbers at 60° pitch. Compare the brick size to the timbers.

Looks like they were propped on your old pics?

That's what I did 4 years ago.

7x3" I think.

I had another look tonight, that block I can move by hand, it's not doing much!

Pah you Englanders thinking 4x6 is a big bit of timber

It will be (purlin) hanging off the roof spars with 6" nails from the top

We dont want to see your big welsh wood Edd.

yeah i agree

most only see the standared 12x4 beams nowadays

its fun when you have to deal with 18x4x or the ackward 18x6s lug heavy things they are

Looks to be on a very shallow angle so the full strength of the purlin is not being utilised, it probably started off perpendicular to the rafters and has turned a little over time. Would now be installed vertically with the joists birdsmouthed over, but that's a bit irrelevant really!
I doubt it would work but even if you could I wouldn't try to twist it back. It's settled over time so your best bet is to just shore up what you've already got the same way you've done the other end. I would prop it and use some 3 X 6 or 8 with a v notch to hold the purlin in place. I would offset the notch so there's a longer section holding the top of the purlin in place to prevent further twisting. The wall looks nice and solid so use some good concrete bolts or resin fix some studs in.

 

[addjunkie]

Whats the other end like?

 

[dobbslc]

Whats the other end like?

The same.

 

[Cato]

Lots of options by previous posters so I'll only add one thing. Whatever you use don't fix it to the purlin as well as the wall. If you do any movement in the purlin will pull/push the wall.

after reviewing your old post on the site

i presume this is the other side ?

Roof trouble!

I've been in the eaves in my house (chalet bungalow if it makes any difference) looking at the roof structure and have found some donkey has cut one of the struts out to extend the bedroom! It's similar to the drawing below except the bottom of the struts are sitting on top of internal brick...

[dobbslc]

Yes this is the opposite side to that post.
I've now just skimmed through that thread again! 4 years on and I'm still flat out at it!

Swear some of mine has a coating of cement wher eit was previous used to tamp some concrete . . . but at least those ones haven't suffered from the woodworm . . .

I spent sometime the first winter spraying everything remotely timber looking . . . and hanging insectocuter lights to get the ones that hatched successfully on the way out . .

 

[brightspark]

The same.

what the hell were they thinking when they built it or a case of the wood wasnt the right length and short if it was me doing it id acro it up knock a hole into the brickwork and insert some 3x3 angle underneath the beam couple of foot long .drill through it and the beam and plate the other side and use long nuts and bolts then cement it in
