CP'ers, need your smarts and ingenuity urgently!
Our plant has grown huge and is falling apart.

As can be seen from the photo, its trunks are long and weak, while the leaves are large and heavy. We've tried reinforcing it with bamboo u-shape sticks pushed into the soil and ropes but it keeps falling apart. Larger pot is no longer an option; the one it grows in is as big as they get. Any helpful suggestions or, even better, a sketch would be much appreciated!
