Although the majority of the roof-work from which I would hang the external room plasterboard ceiling was now complete, there were still some problematic areas that required attention. These mostly involved the end sections of the garage, where I would need something to fix plasterboard onto on the far walls.
Additionally, there was the front section of the garage where I had to install a new timber board into the wall in order to be able to use Joist Hangers to hang the required rafters in this section. Here is a picture of me doing just that:
In the image, I'm using a torque wrench to install some Rawlplug LX concrete screwbolts - I found this to be the easiest way of fixing solid timber structures to the concrete. Initially I tried sleeve anchor bolts for this job: these are fixings specifically designed for masonry that have part of the bolt (the sleeve) that expands when you tighten them, thus gripping the hole. However, the issue I had with these was that it was very easy for them not to grip in the hole, or to grip too early meaning that they wouldn't tighten appropriately. Once this happens, there are not many options but to use a grinder to grind off the head as, once the sleeve is deformed, there is no going back. I found the Rawlplug LX bolts to be plenty strong enough, and the massive advantage of these is that they can be removed if necessary just by unscrewing.
Here is the finished result from the front section:
I also had to do a similar process at the back of the garage: circled in red you can see a smaller board fixed to the wall from which I then hung the joist hangers and subsequently the rafters
Finally, there were some more framework sections that needed finishing that happened to be in tricky areas, such as the below:
These two back-most rafters were physically too close together to be drilled and bolted , so I had to use steel Nail Plates to bridge the connection, through which I screwed many 4x45 wood screws. As you can see, I used multiple plates for each connection, (and had one on the back where possible), thus having one to take the vertical force, and one to take any horizontal force.
