PROBLEM TO BE SOLVED: To provide a shape variable trussed frame, by which a plane can be formed without damaging the structural strength of a truss and which can be folded up in small size and is suitable for usage for a shape variable ceiling and an open-close type roof. SOLUTION: A pair of chord members 1 and a pair of expansion-adjustable post members 4, 4 are mutually combined rotatably and formed in a quadrilateral lattice while a diagonal member 5 is united rotatably between both nodal points of the connection points of the chord members 1, 1 and the post members 4, 4 along one diagonal of the lattice and a minimum unit truss 8a as the fundamental unit of a component is constituted, and a large number of the minimum unit trusses 8a are continuously connected and joined in a latticed shape towards one direction while jointly having the post members 4, thus forming the shape variable trussed frame. A large number of the shape variable trussed frames are separated and juxtaposed, and sections among each shape variable trussed frame is combined by connecting members in constant length, thus configuring the shape variable space-trussed frame. The shape variable space-trussed frame, a ceiling finishing material and a roof sheathing material are combined, thus organizing the shape variable ceiling and the open-close type roof. |
