ABSTRACT:
Apparatus and method for constructing and disassembling a triangular prism-form truss structure in spaced are disclosed. The apparatus includes a triangular prism-form construction fixture and three feed units disposed about the fixture for feeding the triangular frame elements that form the basic unit of the structure, or for removing the elements from the structure. The construction method, essentially automatic, comprises feeding frame elements to the fixture from the feed units in sequence. Fixture forward and backward movement along the fixture longitudinal axis, before and after element feeding, effects fastening of the frame elements to one another. Shifting of completed truss structure sections relative to the fixture is accomplished by periodic axial movement of the fixture. The disassembly method essentially comprises the reverse sequence of the steps of the construction method.
