The gods didn't want you to post, therefore it went wrong.

because..


495m


ameblo.jp/kiyurino-jp/


twitpic.com/photos/pp_komura

The roof of tower frame has been reached!

The only thing is that it will only grow again in the 2nd half of December, but even without the growth it will still be interesting to watch the construction of the 2nd pod that should also start pretty soon (probably next week).

the last jack-up of antenna mean the tower may grow about 130m in just one day?

In theory it could be lifted in 1 day, but the way they are going to do it will take more time.

It's all being explained here:
http://www.obayashi.co.jp/news/skytr...l10_20100724_1

Since it's all in Japanese I will give a quick explanation in English how the spire is constructed.

Fase 1

This was the fase where the spire was put together inside of the core, the spire got lifted from the top to make room to attach new parts at the bottom. This way they could put it together on the ground level with out having to lift all new parts in from the top of the core. This fase is completed.




Fase 2

The are currently in fase 2 of the construction of the spire, the spire is completed inside of the core. The points where the spire is lifted are replaced from the top of the spire to the bottom of the spire in order to make it possible to lift it up above the height of the steel tower.




Fase 3

The next fase can only start when tower body is finished since the spire will be lifted from the top of the tower body. Then the spire will only be lifted inside of the core up to a point where the top of the spire just stick out a little bit on the top.




Fase 4

They won't pull it up to 634m at once since it's still a bare spire, all the antenna's and the other communication equipment will be installed onto the spire as it comes out of the core.



This will mean that the spire will grow in steps, the speed will depend on how fast the equipment will be installed. Remember that it's expensive equipment, it's all being done at 500m in the air and they basically got a year to do it. They start half December with this fase and don't expect it to be T/O well into the new year.

The cranes (or at least one of the two) will stay at the current height until the spire is completely finished. They won't be lowered down for the construction of the 2nd pod.


As the spires grows out the core they will also start with the concrete reinforcement of the core. They will use a slip-form to construct it all the way to the top. This concrete core inside the core will give the tower more stability during typhoons and earthquakes.

More info on the construction of the core (in Japanese):

Yes, almost there! It is so precarious looking with those 2 cranes being so high.

The rise of the antenna will be done in a controlled manner - 1 day might be a little too quick?

The only question is that statement about one of the two cranes staying in place while the second pod is constructed. It looks far enough out from pod #2, but can it reach all the way over to the other side?

Very strange looking at the moment, with the "truss" structure outside...

I think you misunderstood me, they will use 2 cranes for the construction of the 2nd pod. After the 2nd pod is structurally finished they will start with lifting up the spire, then they might only use 1 crane to attach the broadcasting equipment to the spire as it goes up.

For the last level they already lifted only 1 of the 2 cranes and attached it to the tower in such a way that it can't climb or be lowered easily. If they won't raise the other crane later this week it's pretty certain that it will only be used for the 2nd pod from now on.

It's funny, one of the first pictures of the Sky Tree I saw on flickr, about a year ago, was your diagram and here you are posting on this forum! The detail is great.

And momo1435, many thanks for the pics and explanations on the antenna 'Gain' - the construction inside the base of the tower is amazing in itself.

Looking at this building each day, its quite a sight and the cladding on the first Pod and its size - just defies belief.

展望台で貯められた雨水は、地下のタンクに貯められます。
その量は墨田区の全部の家の水に匹敵します。

The rainwater accumulated in an observatory is stored in an underground tank.
The quantity is equal to the water of all the houses of Sumida-ku.

Wow, it's hard to believe that TST is now only 14m off Taipei 101.

10/20








tokyo-sky-tree.seesaa.net/

And the 2nd crane also jumped this morning.

This can only mean that the 2 cranes will stay at this height for a longer period.
