In eight days (on 30/9), 24 lightweight concrete elements will arrive to be placed as the roof on my future workshop. The ones that are 600 mm wide and 6 meters long weigh nearly 700 kg...
I have scoured the internet for instructions and tools. I feel fairly confident about how it's supposed to be done but I'm lacking tensioning braces (need at least two) that are used to pull the elements together.
I can't find where these can be purchased or decent pictures to make one myself.
Very grateful for any help with this!
Hello and welcome.
What do they use to lift the concrete pieces? Are they lifting eyes that are screwed down, or do they use slings around the piece to lift it?
I was thinking if one could create something using a threaded rod and hooks that could be attached to lifting eyes and tighten with.
It is not the lifting that is the problem, but when they are in place and need to be adjusted together. I have found a video on YouTube where the tension clamp is clear. I will try to weld two of those together. Doesn't seem too tricky.
Okay, I'll rephrase then..
If there are holes on the top side of the concrete elements where lifting eyes have been/are, these can perhaps be used to tighten 2 elements together by using 4 hooks and 2 threaded rods to pull them together, hence the question.
There is also some tool (winch?) with a cable between 2 hooks, but I don't know its real name.
Okay now I'm with you! No, there should not be any holes or lifting eyes on the elements. I'm warming up to the idea of threaded rods! I have a couple of sturdy ones (M12 I believe) that could do a good job in some kind of clamp/tension contraption. I have an air-driven impact wrench that could drive them!
