A containment system may include four different widths of panel assemblies, at least four different types of corner assemblies, various types of door assemblies, multiple types of three-way corners or T intersections, multiple types of exhaust panel assemblies, multiple types of wall seal assemblies, and other components that form a modular system capable of adapting to various configurations using a minimal number of fasteners, brackets, and/or clamps. Each panel assembly includes a lower assembly, an upper assembly slideably attached to the lower assembly, at least one adjustment mechanism that interfaces with both the lower assembly and the upper assembly, and a sealing member extending between the upper assembly and the lower assembly.

A sandwich panel includes a first plate member and a second plate member, each of which is metallic, a spacer unit which is metallic and formed in the shape of a rectangular frame, and a core member. The core member is arranged in a region surrounded with the spacer unit between the first plate member and the second plate member. The spacer unit is made up of a plurality of spacers that are formed as separate members. The first plate member and the second plate member are bonded to the core member and each of the plurality of spacers.

Modular wall panels having a frame of a plurality of frame components and at least one wall sheet affixed to the frame. Frame component may have angled ends, straight ends, or a combination thereof. Each end of the frame components may have at least one fastener or at least one corresponding receiver to selectively connect adjacent frame components end on end in forming a frame, including corners. Frames can thus be assembled in the field and are fully customizable. A hub may be utilized with multiple sides having fastener(s) or receiver(s) to interconnect frame components. A wall system includes a plurality of such wall panels connected to one another along the outer surfaces of the frame components of their respective frames.

Modular wall panels having a frame of a plurality of frame components and at least one wall sheet affixed to the frame. Each frame component includes an outer surface with at least one aperture configured to receive and retain an insert therein. The apertures are also configured to permit a cable(s) to pass therethrough for running cables and such through the interior of the wall panel. The frame components may have angled ends, straight ends, or a combination thereof to collectively form a frame which may include corners. A wall system includes a plurality of such wall panels connected to one another along the outer surfaces of the frame components of their respective frames. Connectors and spacers may be inserted into the apertures as inserts and bridge between adjacent panels to selectively connect the panels. Caps may be placed in empty apertures to cover the openings for aesthetic purposes.

Wall panels and methods of constructing a wall system for a building are described. In some embodiments, a pre-assembled wall panel may include a panel frame including a perimeter member defining a perimeter side of the panel frame, first and second wall boards attached to opposite sides of the panel frame to define first and second major sides of the wall panel, each of the first and second wall boards comprising non-combustible material, and a waterproofing assembly enclosing the perimeter side of the panel frame and extending along a full length of the perimeter side, wherein the waterproofing assembly includes a non-metallic elongate member comprising first and second opposing flanges disposed against respective exterior surfaces of the first and second wall boards, and wherein the first and second opposing flanges are attached to the perimeter member.

A demountable wall system includes a frame component. The frame component may include a front channel that receives a panel of the demountable wall system. In addition to the front channel, the frame component may include at least one of a front cover, a removable back cover, a leveling system, a supplemental channel, or a joining system. In some examples, the demountable wall system includes a door support system for movably supporting a door relative to the panel of the demountable wall system.

A collapsible barrier including a substantially rectangular sheet having a first telescopic post and a second telescopic post pivotably connected with hinges. Feet extend from the bottom of the first telescopic post and the second telescopic post. A first-bracing member and a second-bracing member respectively reinforce the first telescopic post and the second telescopic post in a perpendicularly oriented position with respect to each other. A metallic webbing integrated with the substantially rectangular sheet to provide suitable strength and load bearing capabilities. The telescopic posts are configured to extend and retract to a height of a ceiling with a twisting motion. When the feet are aligned parallel with the substantially rectangular sheet the lip of the substantially rectangular sheet allows multiple collapsible barriers to be stacked. The collapsible barrier is useful for providing a portable barrier without the need for drilling into a floor or ground surface.

A demountable wall system includes a frame component that has a base. The demountable wall system also includes a biasing element and a cover that is removably coupled to the frame component. The cover includes a cover body and an engagement projection extending outwards from the cover body, and the biasing element is configured to bias the cover such that the engagement projection engages the frame component.

A functional wall module for at least partially forming an individual space in a building and for positioning and selectively repositioning one or more objects within the individual space. In one implementation, the functional wall module includes a frame having a plurality of frame supports that define an interior space of the frame. The functional wall module additionally includes a bracket configured to support or couple to moveable platforms, the bracket comprising one or more bracket arms extending away from the interior space and from the frame. The functional wall module additionally includes a positioning mechanism within the interior space and connected to the bracket such that the positioning mechanism is operable to reposition the bracket.
