The invention relates to a dome- or sphere-shaped multipurpose building, which is a prefabricated quickly erected structure and can be used for erecting the buildings of various functional purpose, of different number of storeys, both warm and cold, including residential buildings, cottages, industrial, administrative, sport, agricultural, warehouse, temporary portable buildings, arch structures, atrium roof, atrium room, located above the top floor of a building. Technical result of the claimed invention is to reduce the material consumption, installation time, increase the strength and stability of the building, including under conditions of asymmetrical and dynamic loads, and to increase energy efficiency and translucence of the building. The multipurpose dome-shaped building comprises a bearing frame having a base and an apex in the form of polygons of different perimeters, a roof in the apex of the bearing frame coated with a facing material, wherein the bearing frame is made in the form of at least three pyramidal volumetric trusses arranged symmetrically with respect to the base center and rigidly connected to each other in the upper part by at least one horizontal beam, and wherein the volumetric trusses are arranged in such a way that the horizontal distance between closest posts of neighboring volumetric trusses remains the same over the entire height from the base and up to the top of the neighboring trusses.

A portable theater includes a plurality of individual panels assembled together to form a theater enclosure, a plurality of audience seats installed within the assembled theater enclosure, and a projection screen mounted within the assembled theater enclosure. The projection screen has a partial toroidal shaped reflective surface configured to reflect, toward the plurality of audience seats, a moving image as projected by a projector.

The present invention is directed to a novel workstation which incorporates an acoustical dome for increased acoustic and visual privacy for the user. The workstation further is adjustable in height such that it is able to accommodate a range of users from the 5.sup.th percentile seated female to the 95.sup.th percentile standing male according to the dictates of ANSI/HFES100-2007 national ergonomic standard. The workstation is further designed to be in electrical and data communication with other workstations to optimize the workstation density in an open working environment without compromising user privacy.

A geodesic dome structure having a doorway in a vertical plane, includes: a single upper pentagonal planar member provided at a topmost position; five upper hexagonal planar members with vertices thereof meeting facing vertices of the upper pentagonal planar member; five middle pentagonal planar members disposed between the upper hexagonal planar members, with upper vertices thereof meeting corresponding vertices of the upper hexagonal planar member; five middle hexagonal planar members disposed between the upper hexagonal planar members and the middle pentagonal planar members; a single lower doorway hexagonal planar member disposed between the middle hexagonal planar member.

An immersion platform includes a dome configured to display a predetermined scene, wherein the dome includes an outer perimeter. A controller is configured to display the predetermined scene on the dome and to activate the plurality of accessories according to a predetermined timeline. A camera is configured to allow a user to stream the user to other platforms while the user is using the platform.

The invention relates to a space curved reticulated shell structure formed by stacking and combining rhombic dodecahedrons, comprising a one-way curved reticulated shell structure, a positive curvature two-way curved reticulated shell structure and a negative curvature two-way curved reticulated shell structure, the array combined revolution body is generated by rotating the orthogonal array combination body around the space rotation axis by a certain angle; boundary cutting structures are generated by the plane boundary in span direction or the curved boundary in span direction cutting the array combined revolution body; the plane boundary cutting structure respectively generates a one-way curved reticulated shell structure, a positive curvature two-way curved reticulated shell structure and a negative curvature two-way curved reticulated shell structure respectively through one-way bending arching, positive curvature two-way bending arching and negative curvature two-way bending arching.

A method of making a geodesic shape is provided. The method comprises of providing and assembling a plurality of pre-made forms, and a plurality of struts. The pre-made forms have a triangular shape, first and second inner edges, and an outer edge. The length of each inner edge and outer edge are determined by the frequency of the geodesic shape, diameter of the geodesic shape, and known formulas for relating diameter and frequency when creating a geodesic dome or sphere. Using the pre-made forms and struts, a polygonal shape is assembled, each shape having either five or six pre-made forms. The resulting desired polygonal shape and additional desired polygonal shapes made using the same steps are connected at preset angles in known geodesic form and function. The desired polygonal shapes then combine to form a desired geodesic shape. Throughout the process, no struts are operably coupled to other struts.
