A foot assembly for a V-leg assembly of a folding frame system includes a first U-shaped bracket having two legs connected by a web, a second U-shaped bracket having two legs connected b a web, a cylindrical foot member, and a pivot pin extending through a hole in the web of the first bracket, a hole in the foot member, and a hole in the web of the second bracket so that the first bracket, the foot member, and the second bracket are all pivotable relative to one another about the pivot pin.

A building system comprising a plurality of tubes, a plurality of connection nodes comprising tubular sections for connection to the tubes, wherein the tubes are arranged to connect between the connection nodes to form a frame for a building, wherein at least one continuous cavity is formed through at least a portion of the nodes and tubes when the nodes and tubes are connected, the building system further comprising fluid tight seals between the tubes and connection nodes to enable fluid to flow through the at least one continuous cavity.

A new class of polyhedron is constructed by decorating each of the triangular facets of an icosahedron with the T vertices and connecting edges of a “Goldberg triangle.” A unique set of internal angles in each planar face of each new polyhedron is then obtained, for example by solving a system of n equations and n variables, where the equations set the dihedral angle discrepancy about different types of edge to zero, where the independent variables are a subset of the internal angles in 6 gons. Alternatively, an iterative method that solves for angles within each hexagonal ring may be solved for that nulls dihedral angle discrepancy throughout the polyhedron. The 6 gon faces in the resulting “Goldberg polyhedra” are equilateral and planar, but not equiangular, and nearly spherical.

A transverse span for an airform membrane is disclosed that can include a material having a perimeter defined at least in part by a longitudinal edge having opposite ends that terminate at a base edge further defining the perimeter. The longitudinal edge can be configured to couple to a longitudinal edge of an adjacent transverse span of the airform membrane. The base edge can at least partially define a base perimeter of the airform membrane for coupling with a base support structure. The transverse span can also include a load compensated region with a length dimension and/or a width dimension reduced from an intended final dimension to compensate for stretch of the material when the airform membrane is inflated. In addition, the transverse span can include a flare region between the load compensated region and the base edge. The flare region can transition in the length dimension and/or the width dimension between the load compensated region and the base edge.

In this invention, Dome structure is constructed by, “Top connector” (TC) connecting to the “Base plates” (BP) by connecting the “Connecting arch's” (CA) and “Middle connectors” (MC), to form a meridian of a doom. “Middle connectors” (MC) are used to connect “Connecting arch's” (CA) to maintain a specific radius vertically for the entire structure, and to connect adjacent “Connecting arch's” (CA's) horizontally with horizontal bars, to maintain the stability of the structure at each horizontal level, as shown in FIG. 33. The “Middle connector's” are also used to attach another layer of similar dome structure to the structure and to attach accessories inside the structure.

The invention provides a unique injection-molded, slotted, angled hub that connects standard timbers at predetermined angles to build geodesic domes. They form fit over the ends of multiple timbers to transfer load evenly, limit strut rotation and movement, and aid in easy construction of domes. Furthermore they include screw holes that help to snug the timbers flush into its slot to form a durable structure. Being injection molded, they are cost effective, lightweight and through multi directional load transfer, allow lightweight timbers to be used in maximizing the strength at each union. Building with molded slotted angled dome connectors one can assemble a geodesic dome without calculating angled cut for each timber.

An Injection Molded Slotted Angled Dome Connector

This invention provides a novel one-piece injection molded hub that form-fits around timbers to form a geodesic dome without the need for angled cuts.

Wall systems and buildings having such wall systems are disclosed. Such wall systems include parametric mullions each of which is constructed from a plurality of interconnecting components so that the wall systems may be disposed much closer to the building frame than conventional wall systems. Such wall systems may include panels disposed to form convex or concave facades. Such wall systems may also include decorative features superimposed over one or more panels or extending outward from the facade surface. The parametric mullions may be formed into trusses which may be used as part of a wall system or independently of such wall systems.

Disclosed are devices, systems, and methods for self-constructing structures. In particular, a mold for forming a structure includes an inflatable inner balloon, a non-inflatable outer shell coupled to the inner balloon about a base circumference, the outer shell having an apex and an opening disposed at the apex, and a pump in fluid communication with the opening of the outer shell; wherein, when the inner balloon is inflated, a gap is formed between the inner balloon and the outer shell for containing a building material, and the outer shell comprises a dome shape.

A safety enclosure for building structures is an apparatus that provides maintains a safe and healthy living environment and shields hazardous conditions from a surrounding environment. The apparatus includes a structure enclosure, at least one entrance, a plurality of anchoring posts, a plurality of indoor environmental systems, a plurality of indoor maintenance systems, a main controller unit, and a power supply. The structure enclosure surrounds a building and any supplemental buildings. The building may include a variety of extensions as well. The at least one entrance provides access into and out of the structure enclosure. The plurality of anchoring posts secures the structure enclosure with the ground. The plurality of indoor environmental systems ensures livable conditions within the structure enclosure. The plurality of indoor environmental systems ensures the safety within the structure enclosure. The main controller provides a user with manual operation and the power supply provides the necessary power.
