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 panel member for a cyclorama includes a concavo-convex body having integrally-formed first and second side portions with an intermediate portion therebetween. The first side portion, the second side portion, and the intermediate portion have a radius of curvature in a Y-Z plane, and the first and second side portions have a radius of curvature in an X-Y plane that is different from the radius of curvature in the Y-Z plane to uniformly reflect or diffuse sound and light incident on the panel member.

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.

A foam panel is provided, that includes a substrate formed of foamed synthetic resin, a fastening portion having a first end embedded in the substrate and a second end exposed, and a polyurea resin layer covering a surface of the substrate. A prefabricated house includes a plurality of foam panels and is formed by coupling the plurality of foam panels.

A modular geodesic dome construction simultaneously optimizes vertex positioning to be equidistant from a central point and minimizes a number of uniquely shaped triangular panels utilized in construction. The dome construction includes a plurality of triangular panels being coupled together along sides of the triangular panels forming a geodesic polyhedron structure. Each side of each of the triangular panels has a length corresponding to an associated one of only five length factors times a radius of the geodesic polyhedron structure. Additionally, the five distinct shapes of the triangular panels are either isosceles or equilateral triangles.

The present invention provides a modular system for constructing a structure assembly. The system comprises first and second sidewall components each comprising a set of spaced-apart longitudinally oriented grooves disposed in a first face thereof. The system comprises a plurality of rib components, each rib component having a pair of elongated protrusions extending from opposing sides of the rib component and, each protrusion being shaped to matingly engage with at least the first portion of the groove to connect the first and second sidewall components along a face-to-face direction. The system further comprises two elongate key joint members matingly engaging with two respective additional sidewall components to connect the sidewall components with the additional sidewall components along a transverse direction perpendicular to the face-to-face direction in a side to side relationship.

A wall module for a modular wall having a wall segment with a top, bottom, front, back, first end, and back end. A first component of a connector is preferably and extended tongue and is attached to the second end of a wall segment. The second component of a connector is preferably an extended groove in the first end of the wall segment. Preferably, a channel exists along the length of each wall segment at top. Also, preferably either a ring segment or an elongate member is in such channel and is connected to a leg. And preferably the ring segment or elongate member connects to the corresponding element on an adjacent wall segment when such adjacent wall segment has been connected to the first wall segment.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A beam system and method of erecting a supporting arch enables large roofed structures to be erected quickly and economically. The method includes aligning a plurality of structural elements longitudinally; connecting upper corners of the structural elements to upper corners of adjacent structural elements, wherein adjacent lower corners of the structural elements remain unconnected; elevating first and second structural elements in a middle of the supporting arch; connecting lower corners of the first and second structural elements together; elevating third and fourth structural elements adjacent the first and second structural elements, respectively; and connecting lower corners of the third and fourth structural elements to lower corners of the first and second structural elements, respectively.
