ABSTRACT:
The instant invention is a method for achieving a-planar framing configurations which enable the construction of hyperbolic paraboloid surfaces, a multiplicity of which join to create roof structures and enclosures.In particular, the shaping and erecting of connected a-planar quadrilateral frames to create under-framing which can be completed by a simple in-framing, and covered with sheeting material resulting in a new method of constructing enclosures with hyperbolic paraboloid faces without the use of highly trained crews, or the need for elaborate pre-forms or specialized connecting or covering elements.The additional methods of assembly and erection of a hypershelter described herein make possible even greater strength-to-weight ratios and more efficient construction procedures than was possible at the time of the original application. The pre-stressed effects of the twisted framing members, and the progressively rotated orientations of the faces are strength enhancements; and the assembly of whole faces before erection makes possible a great deal of savings in the construction process. As a result of these improvements, it also makes it easier to create various embodiments of hypershelters, here called “domular” and “multi”, that were not noted previously.
