<P>PROBLEM TO BE SOLVED: To provide a skeleton structure that can be made lightweight while suppressing an increase of deformation. <P>SOLUTION: The skeleton structure is formed by arranging a triangular truss unit 1 and an inverted triangular truss unit 2 successively. The triangular truss unit 1 includes one linear first upper chord member 1a, two first lower chord members 1b, 1b, and a plurality of first lattice members 1c connecting the first upper chord member 1a and the respective first lower chord members 1a together, and the inverted triangular truss unit 2 includes one linear second lower chord member 2a, two linear second upper chord members 2a, 2a, and a plurality of second lattice members 2c connecting the second lower chord member 2a and the second upper chord members 2a together. The first upper chord member 1a and one second upper chord member 2a are connected through an upper connecting member 3, and one first lower chord member 1b and the second lower chord member 2b are connected through a lower connecting member 4. The first upper chord member 1a and second lower chord member 2b are not connected, and the first lower chord member 1b and second upper chord member 2a are not connected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
