摘要:PURPOSE:To attempt weight reduction and improvement of reliability in a truss structure suitable for an unfolding structure constructed in the space by rotating and unfolding connecting bars and diagonal members for forming a triangular pole truss element by movement of bonding portions of a triangular bonding member in the axial direction by means of a driving means. CONSTITUTION:When a structure 20 for forming a parabola antenna is constructed by six triangular pole truss elements 10; in respective triangular pole truss elements 10, three connecting bars 11 each of which includes a freely foldable intermediate portion are arranged into a delta shape, and a triangular bonding member 12 formed by rotatably connecting the bonding portion of the connecting bars is provided. A triangular pole truss 14 is constructed in such a manner that the two triangular bonding members 12 are oppositely arranged at predetermined intervals; driving members 13 for folding and unfolding are mounted between mutual bonding points of the connecting bars and bonding parts on both ends are rotatably connected to each other through a bonding member 11a. The driving members 13 have screw portions 13a, and diagonal members 17 of second triangular bonding members 16 are rotated in the unfolding direction by driving driven motors contained in the screw
portions 13a. Thereby, the triangular pole truss 14 is unfolded.
