A collapsible pop-up structure for the rapid erection of buildings includes at least two portals forming two first parallel aspect facades of the shelter, the two other facades each comprising means for vertical articulation, on one hand with respect to the uprights of the portals that they connect, and on the other hand with respect to an axis positioned centrally between the portals. The portals are independent and the uprights of one portal each comprise an internal profile that can be made to slide so as to increase the height thereof in order to impart pitch to the roof, wherein said internal profiles are connected by an upper beam and form a secondary upper portal that can be made to slide into the portal. Means for controlling the sliding are provided in at least one of the uprights.

A device for eliminating auditory and visual distractions for the user. The device is adjustable and features walls comprised of fabric to accomplish its design goal. Extendable poles provide the structure for the device. The tent-like device can quickly expand into its useful position. The device can also quickly collapse. The device can be stored in a storage container for simple transportation.

A modular building unit for construction of a building comprises a structural frame 40 suitable for interconnection to another modular building unit in construction of the building; and a stud frame wall 80/82 internal to and fixed to the frame. The modular building unit is suitable for handling as a shipping container for transport.

A temporary radiotherapy facility for use during renovation, upgrading, and/or modernization of an existing facility. The radiotherapy facility includes a central vault room containing a radiation emitting device and a platform for holding a quantity of radiation shielding material above the central vault room. The platform is supported by shear walls that are disposed outside the sidewalls of the central vault room such that the radiation shielding material is supported and suspended above the central vault room without being in contact with or bearing upon the central vault room or affecting the height or level of the central vault room.

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly. To solve the above problems, the present invention is proposed. A retractable roof with a foldable ceiling is provided. The roof can be used on some expandable structures such as recreational vehicles or mobile houses. Compared to the traditional sliding roof, this invention combines a foldable ceiling inside the roof. The ceiling can split the roof and room which offer a better thermal insulation function.

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly.

To solve the above problems, the present invention is proposed. A multi-layered folding roof fitted with a liftable ceiling is also provided. The roof can be unfolded and retracted in the horizontal direction, and the internal multi-piece ceiling structure will unfold and fall simultaneously with the roof due to the action of the internal slide rail. The invention can be used in a variety of buildings and mobile homes.

The present invention relates to a portable building assembly providing a complete structure configured for onsite construction. The structure once packed down can be delivered to site in a flat packed form most efficient for transportation.

A collapsible modular building is constructed from at least two building modules that are joined together to form the building. Each building module is constructed to be configured in either a collapsed or erect position. In the collapsed position, each module is individually transported to a site by trailer. Once offloaded, the modules are joined together to form the building, this joining together of the modules can be done while the modules are in the collapsed position or in the erect position.

Modular soundproof cabin (1), of the type comprising a perimeter wall (2) having perimeter panels (21, 22, 23, 24, 25), an upper ceiling (3) having ceiling panels (3a) and a lower floor (4) having floor panels (4a), where the panels (3a, 4a, 21, 22, 23, 24, 25) have acoustic insulation properties, where the perimeter panels (21, 22, 23, 24, 25) comprise frames (5) on their inner side, comprising intermediate horizontal struts (6) provided between horizontal lines (90, 91) of perimeter panels (21, 22, 23, 24, 25), and end horizontal struts (7) provided between the perimeter wall (2) and the upper ceiling (3) and lower floor (4); comprising mechanical fixation means, at least, between the frames (5) and the horizontal struts (6, 7), and between the ceiling panels (3a) and the floor panels (4a) and the end horizontal struts (7).
