A retractable roof for a building having a supporting frame and a high structure extending vertically above the supporting frame. The roof has at least one structure section with first and second panels. The first panel is hingeably mounted on the supporting frame at a proximal hinge and the second panel is hingeably mounted on the first panel at a distal hinge. A distal end of the second panel is suspended to the high structure with a distal cable connected to a distal motorized winch. A tackle member connects to both first and second panels adjacent the proximal hinge and the distal end, respectively, and includes a tackle wire that forms a wire side of a triangular cross-sectional shape with the first and second panels. The tackle wire connects to a winch mechanism to control a length of the wire side.

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 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.

An enclosing structure (1) comprising a backfill (2) and a roof (3), wherein the roof rests on the backfill and is attached to it.

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.

A shelter system is shown and described. A hub for a shelter system is shown and described. A frame for a shelter system is shown and described. In one embodiment, the shelter system includes a frame and cover. The shelter may include a hub system. The frame may be collapsible. The cover is configured to fit with the frame. The hub may include a receiver slot, a receiver sleeve and an attachment projection. The result is a shelter system with reduced set up time, effort and requirements and improved strength and ease of use. The inventions may also be considered a shelter kit and/or a shelter and hub method.

An arch building structure includes a plurality of structural arch assemblies, a plurality of purlins, and a plurality of flat roofing sections. The plurality of structural arch assemblies is positioned parallel and offset from each other upon the length of the building. The plurality of purlins is positioned perpendicular to the plurality of structural arch assemblies and radially positioned on the vertexes of the plurality of structural arch assemblies to further strengthen the building. Each of the plurality of flat roofing sections is mounted across a corresponding pair of adjacent purlins from the plurality of purlins so that the building roof can be completed.
