The disclosure presents a composite conduit formwork structure which includes a cylindrical outer casing adapted to bond with a cylindrical inner casing which are maintained at a fixed distance apart by a plurality of radial stanchions. The inner casing and outer casing form an interior void which is filled with concrete during manufacture. The outer casing and inner casing remain in place to protect the structure once completed. A novel method of assembly is also provided whereby radial stanchions are rotated between the outer casing and inner casing. All of the components in a preferred embodiment are formed of a fiberglass material.

The present invention is a novel cable system for a disaster-resistant structure (such as a building or wall) and a method for constructing or assembling the cable system to secure the structure, including the roof of the structure, to a body of cast material such as a foundation, grade beam, base, platform, slab or floor by incorporating flexible cables to resist the very high loads that may occur due to high winds, tornadoes, earthquakes, or other severe storms.

A protective shelter including an enclosure having at least a floor, at least one sidewall coupled to the floor, a door, and a roof coupled to the at least one sidewall. The protective shelter further includes one or more members coupled to the enclosure that support the protective shelter on a substrate and a resilient grouser attached to at least one of the one or more members and in contact with the substrate.

A fire escape chamber includes a hermetically sealable outer cage with outer side wall elements, with an outer floor element and with an outer ceiling element. Fire protection insulation layers are provided on the inner sides of the outer elements with some fastened by pin elements, which protrude from the outer side wall elements and from the outer ceiling element into the respective fire protection insulation layers. An inner cage has inner side wall elements, an inner ceiling element and an inner floor element. The inner floor element is mounted in a supporting manner on the fire protection insulation layer of the outer floor element. The inner side wall elements and the inner ceiling element are formed by a plurality of support structure elements, on the inner sides of which panels are, in turn, fastened. The support structure elements are located at spaced locations from the pin elements.

An ember screen for protecting a building from ember attack comprising a series of individual fire-resistant screens joined laterally. The screens are sealedly attached to the building above any fire susceptible features, typically to a gutter. The bottom of the screens are held in place and sealed to the ground with the aid of sand bags.

A storage system comprising a portable building having a climate-controlled interior space and a plurality of hazardous materials storage cabinets disposed in the interior space. The portable building contains no water sprinklers and no smoke detectors and has a floor that is sealed to prevent leakage of liquid. Each cabinet comprises metal double walls separated by an air space and a liquid-tight containment sump. Each cabinet is configured so that fire cannot spread from a space above a shelf to a space below the shelf. The storage system further comprises an electrical power connection and an HVAC unit mounted to an exterior of the portable building.
