A demountable structure system is disclosed. The demountable structure system may have a roof system positioned atop one or more structural panel(s) and a floor system positioned beneath one or more structural panels(s). The structural panels may have different shapes, configurations, and features, and may support the roof system in order to form a demountable structure. Alternatively, the roof system is omitted and a wall or other structure can be formed from the structural panels. Each structural panel may have other features, such as finish panels, fabric panels, accessory mounts, recessed lighting, electrical outlets, etc. Some structural panels have sound dampening features, such as to form portable musician's sound booth. Thus, a structure may be formed which is both readily disassembled, yet also sturdy.

A fitness module box including a box body having an entrance in a side. The box body includes a framework having a structure and a finishing plate structure finishing outer surfaces of the framework. In the framework top frames spaced apart from bottom frames are connected to the bottom frames using side frames. The fitness module box is provided as a modular structure, such that two or more such fitness module boxes can be connected together, allowing the scale of a fitness facility to be adjusted in consideration of the number of users. An operator may have a significant advantage in terms of the operation of the fitness facility. A user may make a reservation for one of a variety of fitness module boxes at a desirable place and time, and may pay a fee based on the time of use.

An expansion insert for converting an ISO shipping container into a housing unit is provided, the insert having a compacted form reversibly convertible to a expanded form. The insert has a frame assembly torsionally hinged to a roof assembly and a floor assembly. Two pivot walls and a sidewall are also built into the insert. The insert may be compacted for shipping, expanded after insertion into an ISO container, and compacted again on the ISO container.

The present subject matter discloses an outdoor storage shed utilizing molded plastic components or panels. A storage shed structure can comprise foldable corner panels and one or more interlocked teeth couplings. The foldable corner panel can pivot at integrated folding grooves to serve as corners. The interlocked teeth couplings comprise a plurality of protrusions and matched recesses arranged on both sides of engaged panels. Furthermore, the storage shed can come with pre-constructed shelf grooves in the foldable corner panels. The storage shed can have a concaved door frame and a recessed door.

There is provided a structure that is a prefabricated (or systems-built) building space including a floor assembly, modular wall assemblies, and a roof assembly. The structure may at any time be connected to one or more other structures or prefabricated room extensions to form integrated building spaces. The structure is attached in a semi-permanent connection to a helical pier foundation assembly. The structure can include a locking mechanism adapted to be removably fastened to the floor assembly and the foundation assembly.

An extendable structure adapted to operate between a retracted configuration and at least one at least partially extended configuration includes a box-like body, a foldable floor element, and a foldable ceiling element. The box-like body includes a first and a second upright. The foldable floor element is hinged at a lower portion of the uprights and is configured for being folded and spread out. The foldable ceiling element is hinged at an upper portion of the uprights and is configured for being folded and spread out. In the retracted configuration of the extendable structure, the foldable floor element and the foldable ceiling element are completely housed within the box-like body, which defines an overall size of the extendable structure.

A quick-installation soundproof cabin includes a soundproof cabin frame, an end sealing assembly, and a quick-installation mechanism located between the soundproof cabin frame and the end sealing assembly. The quick-installation mechanism includes a supporting body located at a bottom end of the soundproof cabin frame, and the supporting body is protruded towards a direction close to the end sealing assembly from the bottom end of the soundproof cabin frame, to form a supporting structure that is suspended, and the end sealing assembly is configured to be placed on the supporting structure and turned over to an assembly position mated with the soundproof cabin frame. The assembly between the end sealing assembly and the soundproof cabin frame is convenient and efficient.

An enclosure component having first surface layer, a core layer and a second surface layer. The core layer has three rectangular foam panels, each with a first edge, an opposed second edge, a third edge separating the first and second edges and an opposed fourth edge separating the first and second edges. The second and third foam panels are identical, and each has an internal passage between the first and second edges that is offset from the mid-point of the panel, and an elongate recess on a surface of the panel spanning the distance between the first and second edges. The fourth edge of the first panel is arranged side-by-side with the third edge of the second panel, and the third edge of the first panel is arranged side-by-side with the third edge of the third panel. An elongate reinforcement spline is in each recess. The first surface layer is bonded to the core layer, and the second surface layer is bonded to the core layer.

A system, elements of the system and a method of forming scalable, compatible and resilient building structures. Preferably, one or more of (i) standard intermodal containers or racks (steel cuboidal versions as well as flat racks typically used on cargo ships); (ii) pallet racks (steel frame versions typically used in warehouses), and/or (iii) boat storage racks (steel frame versions typically used in marinas) are utilized to form a main structure/assembly (e.g., outer shell or frame) of a building structure that is easily assembled with width ranges from, for example, 24 feet wide to 40 feet wide, a length of 40 feet or longer and multiple stories or levels (e.g., 2 to 4 stories or levels). Preferably, existing portions of containers and associated racks are used to interconnect these members/elements (e.g., casting corners or fork-lift receiving channels/sections/portions) to form scalable, compatible and resilient building structures.

Self-standing, thermally-insulating, noise-insulating, seismically-insulating, water-insulating, electromagnetic-insulating superstructure, whose overall internal volume is filled with rigid and lightweight granules, in which the dwelling rooms are immersed. The lightweight granules are spherical, porous or hollow, they have no binder and are scattered. A gas-tight skin clads all the outer surface of the superstructure's shell and the walls of the dwelling quarters. Gas-tight bay-frames of conical outer shape are embedded in the openings and bays. The entire volume, made up of the scattered granules, the plates, the bay-frames and the gas-tight skin, is under gas-vacuum. This gas-vacuum is lifetime-controlled by a vacuum pump which is installed in situ. The outer casing and the inner walls are braced by the volume of granules stiffened by atmospheric pressure. A plurality of ion-polarized layers, vaporized on overlay metallized polymer vacuum sheets, are inserted between the rigid plates and the gasproof skin.
