This is because you don't have Beams attached to you new node , it's just fall appart.

Iv'e made a simple beam structure to show you :

Code:

     "beams": [
          ["id1:", "id2:"],
          {"beamPrecompression":1, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0},
          {"beamSpring":2501000,"beamDamp":250},
          {"beamDeform":175000,"beamStrength":890000},
          ["rrfh1", "f13"],
          ["rrfh1", "f13l"],
          ["rrfh1", "f13r"],
          ["rrfh1", "f11"],
          ["rrfh1", "f11ll"],
          ["rrfh1", "f11rr"],
          ["rrfh1", "f18"],
          ],

Now to make it work you need to adjust your node position , add some Beamn to make it more solid
