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.

A dome- or sphere-shaped multipurpose building is disclosed, which is a prefabricated quickly erected structure and can be used for erecting the buildings of various functional purpose, of different number of floors, both heated and unheated, including residential buildings, cottages, industrial, administrative, sport, temporary portable buildings, arch structure. 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 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.

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 can 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 modular self-supporting arched ceiling structure has a plurality of interconnected modules each extending in a first direction over an arc and arranged one after the other in a second direction which is transverse to the first direction, with each of the modules being composed of a plurality of interconnected panels located adjacent to one another in a direction of elongation of each of the modules, and each of the panels has two plates spaced from each other to form therebetween a space which is filled with a cellular material with one of the plates composed of a plurality of strips of a heavy-duty high-modulus material.

A novel work station 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.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates arranged around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.

The invention is a system and method for building a polar zonohedron structure from precast cement panels. The building system may include a plurality of panels configured to register with each other. Each panel includes a precast cement base with side walls enclosing a cavity within the precast cement base. The panels include at least one ridge protruding from at least one surface of a side wall of the panel and at least one aperture on at least one surface of a side wall of the panel. Each ridge is preferable configured to interlock with each aperture; in his way, the panels interlock with each other to form the polar zonohedron structure.

A method of creating and attaching membrane panels of thin film, fabric or laminate to a tubular framework, that keeps the membrane tight over a wide range of air temperature and effectively seals the edges and hubs to provide a weather tight enclosure. A second aspect of this invention is a complete system for building enclosed geodesic domes and space frames using this method and addresses anchoring, external shading, venting, creating entryways and interior partitioning of said geodesic domes.

An architectural building block system including a block having three side walls, each having an inside surface and an outside surface, the three side walls cooperate to form a triangular tube, the outside surface of each of the three side walls extending from the inner surface to the outer surface and the inside surface of each of the three walls is disposed substantially at right angle to each of the inner surface and the outer surface; and three channels, each channel disposed on one of the three side walls on the inner surface, wherein each channel extending from the inside surface to the outside surface of one of the three side walls and each pair of the three channels configured to receive a rebar.
