A panel for a building structure has a predefined curvature. The panel has a generally rectangular shape with a curvature, such that the panel has a convex outer surface and a concave inner surface with a set of side edge regions and a set of end edge regions. The panel is at least one mineral wool fibre slab with a plurality of first strips adhered to the outer surface and a plurality of second strips adhered to the inner surface.

The present disclosure provides a multilayered structural and material system assembly comprising a first layer and a second layer, each of the first and second layer comprises a plurality of slender structural support elements (1), wherein a plurality of anchoring members (2) connects the first layer to the second layer to form a skeleton of the multilayered structural and material system assembly; and a fabric (3) harmoniously integrated into a substantial part of the skeleton to define a plurality of singular models (4), wherein the skeleton comprises a plurality of unit cells (5) arranged in a repeating pattern, each having a first central axis and a second central axis, each unit cell (5) of the plurality of unit cells (5) in the first layer is in a horizontal offset displacement of a corresponding unit cell (5) of the plurality of unit cells (5) of the second layer.

A building panel is provided. The building panel includes an exterior wall portion, an interior wall portion, a pair of opposing sidewalls, a first end portion and an opposite second end portion. The pair of opposing sidewalls spacing apart the interior wall portion from the exterior wall portion to define a cavity therebetween. The exterior wall portion, the interior wall portion and the pair of opposing sidewalls are arcuate in shape to define the building panel. The first end portion has a slip lock slot extending between the pair of opposing sidewalls. The second end portion has a slip lock tab member extending between the pair of opposing sidewalls. The slip lock slot of the building panel is configured to receive the slip lock tab member of a second building panel to adjoin the first and second building panels in a continuous fashion.

Structural plates and methods of constructing arch-shaped structures using structural plates. Structural plates may include a combination of features including: an outer structural plate having adjacent circumferential apertures respectively spaced nominally greater than adjacent circumferential apertures of an inner structural plate; and the outer structural plate having nominally 5 enlarged or differently shaped circumferential apertures (as compared to circumferential apertures of the inner structural plate) such that the embodiment structural plates may be radiused to a variety of different radii while achieving desirable overlapping alignment of apertures along overlapping circumferential edges for receiving fasteners therein. Joiner plates may be provided for interconnecting structural plates along transverse edges in a non-overlapping arrangement, 10 thereby reducing the quantity of structural plate material that otherwise would be needed for a given circumferential length of the arch-shaped structure.

It is known that panels moulded for structural use can be subject to undesirable levels of shrinkage and this can complicate their end use or a building made from them. It is an object of the invention to go at least some way to addressing this problem. Accordingly there is provided a method of significantly reducing panel shrinkage in the production of a structural building panel. The method involves spraying polyurethane foam onto a rigid open mould such that the foam substantially embeds mesh, which prevents or significantly reduces shrinkage of the polyurethane foam. A skin of polyurea is then sprayed over the polyurethane to enhance structural strength of the panel.

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.

The present invention discloses a self-supporting prefabricated construction system that does not require a structure and has an arch-shaped configuration of different dimensions, intended for building living spaces and various types of uses. The present invention is based on modular structural elements that have the following configuration: undulating modules for the configuration of various types of roofs, that can be used in different kinds of spaces, wherein said modules are joined in an overlapping manner to generate rigidity and stability to the structure, making up completely sealed and waterproof spaces through various joining mechanisms. These curved undulating roof modules are of two kinds: curved ridge modules, whose size will depend on the dimensions of the intended arch, and curved wall modules. The system can have modules for different types of facades and interior dividing walls, which have a straight shape with obtuse folds.

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.

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.

The invention is a structural connector used as a component to construct an arch consisting of a plurality of closely adjacent, polygonal rows of stringer beams. The multiple row polygonal arch is a low-cost, general purpose support structure for bridges, shelters and arbors applicable to many cost-, time- or environmentally-sensitive situations. The invention is a Y-shaped connector, typically made of sheet metal, with three brackets, two upper brackets and a lower bracket, which collectively enable a union of three beams forming one node of the multiple row polygonal arch. Using these Y-shaped connectors to join the beams at each node creates the arch structure, and additionally provides the features of cantilevering, modularity, generic component shape, reusability and safety. The invention is applicable to a variety of structures such as: pedestrian and vehicular bridges, shelters, arbors, as well as jewelry, furniture and toys.
