Abstract
A roof or ceiling structure for buildings in the nature of a "space frame" or three-dimensional truss, including substantially planar panels and supporting struts and a method for producing the structure on-site. The panels serve a dual purpose as structural members interconnecting the struts and as surface elements for a roof or ceiling. Two panels spaced parallel to one another are interconnected by equiangular struts to form an array of tetrahedrons throughout the three-dimensional structural member. Each panel is made up from sheet material, and the seams between panels are accommodated by rotating each layer of panels relative to those adjacent to it so that the seams overlap abutting sheet surfaces in differing angular attitudes.
