Hi Rahim (and all others)!
I have created this post to summarise the research I did on the spot for the TAKENAKA Crown Structure Demonstration.
Some pictures are stitched together as you can see. All of them you can click to see magnified and download if you need.
On the bottom of the page is a COMMENT field, where you can put your comment. We can discuss there, or yu can send me a message on Whatsapp.
Let’s start with a general picture of the structure:
You can click on it and you will see all the anchor points for lower leafs (or petals). I marked them here:
As You can see, there are no anchors on the overhanged, “under-the-roof” side of the petals. On the bottom of the structure, there are 2 points, that we could use to re-direct the technitian, but it would be way too far to reach the surface:
The only way we could bring the operators closer to the surface of the structure is by installing the tentioned rope under the petal (horisontaly) using the anchors on the edges of petals.
Ok, now some more pictures of the leaf:
Access to the structure is via ladders and hatch (hatch is also used to access the top of the structure from the inside (2 long, vertical petals).
Some more views for the the lower petals:
Now the top structure:
The anchors are running along the edge on the side and the top. The inside of the Petals is hollow.
The last anchor points inside are pretty far from the top edge, so I would suggest to bring a pole and tape, to clip the lanyard to the bolt (otherwise we would have to aid climb vertically to reach the top.
Some more pictures from all over the place, mainly anchor points:
The plates are quite soft, easily bend. We need to bring stiff edge protectors (wood) to avoid damage.
