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 instant invention has the
advantage that lateral forces are resolved directly along the leg members forming triangular openings at its periphery, and by the triangular configurations resulting when the tension restraining member is added to the framework. Triangular openings formed during construction can be used for doorways and windows without the need for dormers or skylights. The construction minimizes the number of braces and edges, there being a minimum of faces joining to form the edges. The over-all configuration is one which provides exceptional resistance to lifting or being torn apart by the wind, an anti-kiting effect which is most optimized in the preferred embodiment, due to its large volume per surface area. This space efficiency also helps to make the hypershelter more economical to build, and more
environmentally friendly than conventional structures. The inherent strength afforded by its over-all shape also reduces the amount and weight of material needed. Additionally, such structures are ideal for use as roofs over other
environmentally friendly enclosures, such as those made of
hay bale, cob, cord wood, etc.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.
