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.

A method and apparatus according to which a blast resistant shelter is assembled. The blast resistant shelter includes first and second structural members, a third structural member coupled to the first and second structural members, a first airway adjacent the third structural member, and a first blast panel pivotably mounted to the third structural member and adapted to pivot thereabout in response to a blast wave. In a first configuration, the first blast panel is detachably connected to a first portion of the blast resistant shelter and prevented from pivoting about the third structural member so that the first blast panel obstructs air flow through the first airway. In a second configuration, in response to the blast wave, the first blast panel is detached from the first portion of the blast resistant shelter and permitted to pivot about the third structural member to permit air flow through the first airway.

A quonset style building is provided with an arched-roof defining a width, length and height, and tower supporting the roof adjacent its apex. The tower separates storage areas on opposite sides of the building. The tower also permits the building height and width to be increased over conventional quonset buildings, and allows the width to be 3× the height, while withstanding typical weather forces, including wind and snow.

An acoustic isolation booth for providing a space for noisemaking out of earshot from other parties. wherein: the acoustic isolation booth comprises a shell comprising at least two compartments, an intermediate wall, a plurality of outer walls, a ceiling and one or more entryways. The shell comprises a shell width, a shell depth and a shell height. The two compartments comprise at least a first compartment and a second compartment. each of the two compartments comprises a compartment depth, a compartment width and a compartment height. A first side wall, the intermediate wall and a second side wall are configured to divide a space within the shell into the first compartment and the second compartment.

A canopy for selectively covering an area, such as a sports field includes at least two beams which span the area, at least two cross beams which are displaceable along the beams, a cloth which is attached to the cross beams, a drive which is configured to displace the cross beams with the cloth attached thereto along the beams, and a substantially flexible tensioning member fastened between the cross beams.

A portable erectable shelter may include a pair of wall panels arranged outermost from a pair roof panels. The pair roof panels may be between the pair of wall panels in a collapsed, vertical position of the shelter. The portable shelter may include a first outer wall truss link rotatably fixed to a sidewall of a first wall panel and having a first end pivotally secured to a first corner of a first roof panel and a free end opposite the first end. The portable shelter may further include a first outer roof truss link rotatably fixed to a sidewall of the first roof panel and including a first end pivotally secured to a first corner of the first wall panel. The first end of the first outer wall truss link may be arranged to abut the first end of the first outer roof truss link in an erect position.

Method and apparatus for covering an area is disclosed. The apparatus includes a plurality of bases located near a first side of the area and positioned substantially normal to ground, a plurality of flexible rods connected to the bases, and covering material secured to the flexible rods. The covering material crumples into a compact form when not spread out. A stabilizer may be used to provide stability and strength to the bases. The flexible rods are bent toward a second side of the area and attached to attachment mechanisms at the second side. The covering material is spread over the area along the now bent the flexible rods, thereby covering the area. The covering material may be fastened to one of the bases, to one of the attachment mechanisms, or other structures. Guy lines may connect the flexible rods to stable articles to provide additional stability.

The present disclosure discloses an air-borne multilayer film building structure which includes an independent film, a heat-insulation structure covering the independent film, and an airbag cover covering or an outer film cover covering the heat-insulation structure. The heat-insulation structure is installed on the outer wall of the independent film and includes at least two heat-insulation layers sequentially from inside to outside. Each heat-insulation layer is formed by paving a plurality of heat-insulation panels, the heat-insulation panels in every two adjacent heat-insulation layers being installed in a staggered manner. The outer heat-insulation layer covers a seam of the inner heat-insulation layer thereof. The air-borne multilayer film building structure has the advantages of good heat-insulation property, good airtightness, convenience in construction and the like.

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.

Arch structure defining equidistant points along a radial curve and comprising uniformly-sized, standard stock, elongated rectangular cross-section stringer members, uniformly-sized, standard stock, elongated rectangular cross-section arch members each having a midpoint and first and second angled ends of equal but opposing to one another angular magnitude, each arch member adapted to converge crossways on and completely abut a side surface of two non-adjacently positioned stringer members, each of the arch members further being adapted for undergirding a stringer member located between two non-adjacently positioned stringer members at the mid-point of the arch member, each arch member adapted for being oriented in scissor-like crossing relationship to another arch member, a plurality of fasteners, and where needed at least one tensioning member preferably attached between end stringer members, or alternatively between foundation members, the tensioning members and fasteners making the arch structure fortified to be as if monolithic.
