A geodesic dome-like structure of the disclosure is constructed from a plurality of generally equilateral triangular panels whose sides are each defined by a plurality of elongated rods extending in spaced relationship to each other. Opposite ends of the rods associated with each panel side are secured to the ends of the rods associated with the other two sides. A plurality of generally planar hinge plates are fixed to the rods in a longitudinally spaced relationship and have their planes oriented perpendicular to the elongated direction of the rods. Pintles pivotally interconnect the hinge plates associated with adjacent panel sides about axes intermediate the rods so that the panels pivot relative to each other about axes located outwardly from their sides. The pintles take the form of elongated pintle rods or headed pins. Preferably, two elongated rods are associated with each panel side and in one embodiment the hinge plates have triangular shapes while in another embodiment the hinge plates have washer shapes. The two elongated rods associated with each panel side are spaced radially with respect to the dome structure and the pintles are located radially intermediate the rods as well as intermediate the panel sides so as to provide a high strength interconnection between the panels. Enclosed openings in the hinge plates may receive the panel side rods in an inserted relationship or slots in the periphery of the hinge plates may receive these rods intermediate their ends during assembly. When metallic hinge plates and rods are utilized, the hinge plates are fixed to the rods by welding after being received within the hinge plate openings or slots and the ends of the rods are then secured to each other by welds as well.
