A soundproofing structure comprises a jacket having an external surface and an opposite internal surface defining an inner compartment. A resilient and deformable soundproofing material is contained within the Inner compartment and engages the internal surface. Constricting elements are mounted to the jacket for constriction of the jacket to provide inner surface pressure against the soundproofing material for compression thereof. The constricting elements are releasable for selectively releasing inner surface pressure against the soundproofing material for expansion thereof against the inner surface. The soundproofing structure defines a size that is selectively modifiable by selective releasing of the contacting elements.

A portable workstation includes a base having a perimeter and a plurality of base fasteners positioned along the perimeter, a first sidewall with a side and a plurality of sidewall fasteners positioned along the side, and a second sidewall with a side and a plurality of sidewall fasteners positioned along the side. The first sidewall is coupled to the base by positioning the side of the first sidewall along the perimeter such that at least one sidewall fastener of the first sidewall couples to one of the base fasteners, and the second sidewall is coupled to the base by positioning the side of the second sidewall along the perimeter such that at least one sidewall fastener of the second sidewall couples to one of the base fasteners. The first sidewall and the second sidewall can be coupled to the base in different positions relative to the base to thereby change the configuration of the workstation.

A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.

The disclosure provides systems and methods for fastening wall and ceiling panels, such as drywall sheets, to framing members. The back side of the panels comprise a first touch fastening component of a touch or hook and loop fastening system configured to removably couple with a second touch fastening component of the fastening system. The second touch fastening component is provided on an outer surface of framing members that are configured to physically support the panels. The second touch fastening component may be coupled to a framing member, or may formed integral by the framing member. Some framing members may comprise a stud/joist, a c-channel, a fixed furring strip or an adjustable furring. The disclosed systems and methods may form walls, ceiling, partitions and the like.

A monolithic corner encapsulates one or more panels while maintaining structural integrity and maintain hygienic properties. The corner may securely receive one or more panels and provide flexibility to easily adjust the one or more panels. The corner may simplify installation and an ability to adjust connected panels without compromising safety, installation time, and sterility.

An extendable arm includes first and second rigid members forming a cross unit. Each rigid member includes one end portion including one of end coupling shafts, the other end portion including the other end coupling shaft, and a middle portion including a middle coupling shaft. The one end portion of each rigid member includes a bottom-side outer side surface that surface-contacts a base surface when the extendable arm in an extended state is placed thereon. The other end portion of each rigid member includes a top-side outer side surface extending parallel to the bottom-side outer side surface of each rigid member. The middle portion of each rigid member includes a middle strip region passing through a middle coupling shaft and perpendicular to the bottom-side outer side surface and the top-side outer side surface.

A dividing screen structure has at least two screens and at least one assembling member mounted on one side of one of the two screens for connecting the two screens together. Each screen has a frame with at least one magnet on each side for pairing with the assembling member; the assembling member comprises at least two magnetically attracted U-shaped securing members, and each securing member has a back portion, two side portions and an opening.

A veneer panel may include a face veneer, a first inner layer bonded to the face veneer, a second inner layer bonded to the first inner layer, and a thermally conductive backing layer bonded to the second inner layer. The first inner layer and the second inner layer are treated with a flame retardant. The first inner layer is disposed between the face veneer and the second inner layer, and the second inner layer is disposed between the first inner layer and the thermally conductive backing layer.

A modular paneled partition includes a first pane panel defining a first panel bottom edge, a first panel upper edge, and a first panel thickness; a second pane panel defining a second panel bottom edge, a second panel upper edge, and a second panel thickness; a wall bottom edge structure including a fixed profile and a movable profile supporting the first and second pane panels and engaged with the fixed profile along an adjustment direction, and means for adjusting position of the movable profile, the movable profile defining a first and a second outer longitudinal sides, and a third side between the first and second outer longitudinal sides. The movable profile has a first bottom channel accommodating the first panel bottom edge, and a second bottom channel accommodating the second panel bottom edge.

A guard system is disclosed for protecting patients and medical health professionals from the transmission of airborne contagions during the administration of vaccinations. The system includes a frame having a generally rectangular shape; a transparent sheeting attached to the frame creating a barrier against the transmission of airborne contagions, the sheeting having a front side opposite a back side; an aperture in the transparent sheeting, the aperture sized for administering a vaccination to a patient seated on the back side of the transparent sheeting from the front side; a movable screen portion for covering at least a portion of the aperture; wherein the movable screen portion moves from a closed position to an open position to facilitate the administration of the vaccination.
