Rear Verandah - WIP

**Glenn.Visca** · 10th May 2016, 01:02 PM

Here we go with this year's major project.

A verandah attached to the rear of the house - measuring approximately 10m x 5m. Gable roof (on the long length). Plans are all approved - owner builders certificate obtained.

The roof will be Sunglaze 4/800 - which is a solid polycarbonate standing seam system - but more about that when we get closer.

The first step is to install the rafter strengthening brackets. These are from Stratco - a 10mm gal steel jigger with adjustable flanges on the outside to which the verandah beam is attached. They were the only things I could find that allowed the installation of a 200mm box gutter between the new verandah and the existing house (which I am told is the requirement in Victoria. I considered the units that attach to the top plate and project up through the iron, but the verandah is already >2.7m off the ground and I didnt want to make it any higher.

The rafter brackets are installed on each rafter (which are at approx 800mm centres), and bolted to the existing house truss with 4 x M12 bolts. In addition, a 90x45 MGP10 stiffening member is bolted on the opposite side of the existing house truss from the bottom chord to at least 300mm past the 1st web frame with M12 bolts at <=300mm centres.

The house has a colorbond roof, so to make all this happen, we had to remove all the iron and the foil insulation on that section of roof, then install the rafter brackets and stiffening members, and then put the roof back on.

The first photo shows the rafter brackets, the second showing the opposite side of the trusses with the stiffener installed.

Thanks for looking...

Looks like I need to seat in the front row.

good time to new foil down before roof goes back on, will be on the bench watching

Thanks lads. And you are right .. Rather than fighting with the old foil insulation, a nice new lot was installed.

Hi GV
I don't seem to be able to find the fascia connector brackets that you're using from stratco. Have you got a link to that or know what they called? Good work by the way, will be watching your progress with interest.

Hi JOT,

Let me tell you, they were pretty hard to find. I had no issue finding the Dunnings units at the green shed - but they werent adjustable - and only projected a poofteenth past the original quad gutter - and I didnt want add that much extra roof area into the existing gutter. I also spoke with a plumber who made the same recommendation ... yet just about every verandah you see attached to a house feeds into the existing gutter !

Here is a link to one of their manuals - refer page 3:

Here is a link to a youtube video:

The Stratco SKU information is as follows:
The arm section is part# ARSBRAA
The tab section on the front is part# ARSBTAB

In total, they are about $100 each. I just rang my local Stratco store - they took credit card payment over the phone and ordered them in.

If you want a Sketchup component - Here tis... (I hope)

A good and satisfying project to take on Glenn!!

I like the look of those brackets.

**justonething** · 11th May 2016, 07:28 PM

I've used these, but they were for a small lean to verandah, What you using is excellent for a such a substantial build.

**Glenn.Visca** · 11th May 2016, 08:17 PM

Yes artme/JOT .. They are pretty substantial. Over 1100mm long 50mm x 10mm flat steel.

Had my timber delivered this afternoon. Time to start painting [emoji15] ... I really don't enjoy painting.

When I was planning this project out, the building consultant told me I could bolt the posts to the existing patio slab of it was more than 100mm thick .. Which it is.

I called the company that makes the bolt on stirrups today to ask them a question. Bloke was very nice and asked me how I was going to anchor them.

"Ramset Ankascrews" says I. He said he has had engineers suggest it is best to 1/4 fill the screw hole on the concrete with epoxy for added strength.

Anyone have a view on this ... Good and bad ?

**justonething** · 13th May 2016, 10:28 PM

I think you should use either ankascrews or chemset anchors. No epoxy with ramset ankascrews because you can't remove them if you've made a mistake. Chemset are stronger Just go with that.

Thanks jot ... Presumably chemset can't be removed either once set ?

**justonething** · 13th May 2016, 11:00 PM

You use these anchor studs with the epoxy, make sure you use epoxy, or the chemset polyester. They are used the same way as dynabolts, just stronger and more consistent.

**rwbuild** · 14th May 2016, 11:00 AM

Just make sure you use either galvanised or stainless, Iv'e lost count of the number of post anchors that have rusted out because they skimped on a few cents difference, remember, you are liable for any failure.

Oh yes ! Gal all the way here !
