A stud rail system comprising at least one stud rail assembly. The at least one stud rail assembly comprises a plurality of rail portions, a plurality of cross portions, where a plurality of sets of support openings are formed in each of the plurality of the cross portions, a plurality of pin projections, where each rail portion supports at least one pin projection, a plurality of support assemblies, and a plurality of support projections, where each support projection is supported by one of the plurality of support assemblies. Each of the support projections extends through one of the support openings in each set of support openings such that the rail portions are rotatably connected to cross portions at a plurality of axis points to allow the stud rail assembly to be reconfigured between a collapsed configuration and an expanded configuration.

A system and method for primarily erecting curvilinear buildings using a plurality of interconnected structural tubes/sandwich panels is provided. Fabricating structural tubing comprises: connecting a fibrous and flexible lining to an inner surface of a flexible outer membrane, wherein the lining is saturated in a curable material that forms into a solid foam material when cured; and curing the curable material. Fabricating a sandwich panel comprises: connecting a first fibrous and flexible lining to an inner surface of a first flexible outer membrane, wherein the first lining is saturated in a curable material that forms into a solid foam when cured; connecting a second fibrous and flexible lining to an inner surface of a second flexible outer membrane, wherein the second lining is saturated in a curable material that forms into a solid foam when cured; and curing the curable material of the first lining and second linings.

A tornado resistant/proof residential housing unit that is built to withstand natural disaster conditions resulting from tornadoes, violent storms, and fire. An internal concrete reinforced core layout gives the unit its structural strength, as well as the versatility needed to face natural disaster conditions while providing absolute resistance to heavy winds such as those caused by a tornado. The unit has an external facade which mimics the exterior appearance of a typical subdivision home.

A new prefabricated wall panel is the basic unit of a new, more efficient and stronger wall system. The wall panel is manufactured from a plurality of foam sections sized to leave vertical and horizontal voids into which concrete is later poured, each foam section having an inner and outer surface and two sides; and a plurality of fastening strips. The fastening strips are longitudinal metal strips being situated between the sides of two foam sections. Each fastening strip has two longitudinal fastening strips projecting perpendicularly to the longitudinal fastening strip and the fastening strips being adjacent to the outer surface of the two foam sections. The fastening strip also has a plurality of clearance holes in the longitudinal fastening strip, a plurality of embed tabs projecting from the edge opposite the fastening strips, each embed tab having at least one hole, and between each pair of embed tabs, a foam tab to hold the two inner sides of the foam sections in place and partially separate the foam sections from the concrete to be poured into a form.
