PROBLEM TO BE SOLVED: To realize the lightening of a folded plate structure. SOLUTION: In the folded plate structure forming a frame such as a roof surface by combining a plurality of polygonal plates 1, bundle materials 4 projected outside surfaces are mounted at approximately the central sections of each plate, and chord members 5 are stretched among the front ends of the bundle materials and each apex of the plates respectively. A poly-pyramidal shaped roof frame in which each joining section is formed in ridgelines by mutually joining the side sides of the trapezoidal plates while the bundle materials installed to each plate are projected to the inside of the plates and tension members 7a are stretched so as to be formed in an annular shape among the mutual front ends of these bundle materials. The top sections of each plate are connected by compression materials 6a.
