Each of the SIPS may be configured to span between a floor and a ceiling of a building unit. An example method is disclosed for assembling an end wall panel to a floor panel.

The invention provides an acoustic panel comprising a plurality of parallel-arranged elongated cavities, wherein each cavity has a first cavity wall and a second cavity wall tapering to a cavity back end and defining a cavity opening angle (γ) having a value in the range of 0°<γ<90°, wherein the first cavity wall and the second cavity wall comprise a light-reflective material, wherein each elongated cavity at the cavity back end of the elongated cavity accommodates a light source having a light exit surface, wherein the first cavity walls hide the light exit surfaces of the light sources when the acoustic panel is viewed along a normal to the acoustic panel, and wherein the acoustic panel further comprises sound reducing material.

A fire-shielding U-shaped outer frame element adapted for supporting a side of at least one wall element in a wall construction, said outer frame element being elongate and comprising a bottom part and a first side flange and a second side flange extending at an angle to the bottom part, interior surfaces of the side flanges being adapted for extending along exterior surfaces of the wall element. The outer frame element (1) comprises a plurality of perforations (15) and a first elongate strip (16) of a material having thermal shielding properties and being arranged on a surface of the first and/or second side flange (13, 14) of the outer frame element (1) so as to shield the wall element from heat from a fire. A set of parts include an outer frame element and a fastenings means for use between wall elements when making a wall construction.

A mountable panel includes a panel body and a hanger body. The panel body includes front, rear, longitudinal side and lateral side surfaces, and a channel having a recessed portion recessed from the rear surface and a leg portion extending into the panel body from a first longitudinal end of the recessed portion. The hanger body includes a base portion disposed in the recessed portion of the channel and recessed from the rear surface of the panel body, a leg portion extending forward from a first longitudinal end of the base portion and into the leg portion of the channel, and a hook portion extending rearward from the base portion.

A fire-rated reveal piece and wall assemblies or other assemblies that incorporate the fire-rated reveal piece, in which the reveal piece can include an intumescent or other fire-resistant material strip. The reveal can be attached adjacent to a corner, flange or leg of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement. A fire spray material can be applied over a portion of the reveal piece.

Certain example embodiments relate to an acoustic wall assembly that uses active and/or passive sound reverberation to achieve noise-disruptive functionality, and/or a method of making and/or using the same. With the active approach, sound waves in a given frequency range are detected by a sound masking circuit. Responsive to detection of such sound waves, an air pump (e.g., speaker) is used to pump air in the wall assembly to actively mask the detected sound waves via reverberation and/or the like. The wall assembly may include one, two, or more walls, and the walls may be partial or full walls. With the passive approach, sound waves in a given frequency range are disrupted via features (e.g., holes, slits, etc.) formed in and/or on a wall itself. These techniques may be used together or separately, in different example embodiments.

An interior building structure is provided and comprises a plurality of side walls, each comprising an exterior surface, an interior surface, a bottom end, and a top end opposite the bottom end, the bottom end being connected to a lower base building slab of the base building and the top end being free. A lateral support structure is further provided that extends from a first wall to a second wall of the plurality of side walls. Airspace portions are formed from gaps between the side walls and the base building structure, decoupling the walls of the interior building structure from the base building structure.

A room divider system comprising at least one panel having a first sheet and a second sheet spaced apart by means of at least one lath, wherein said system further comprises a connector forming a rigid structure for associated equipment, said connector being configured to be at least partially inserted in a cavity formed between said first and second sheets, wherein the connector is arranged to be attached to the at least one lath.

An object handling system is described, the system having two substantially perpendicular sets of rails forming a grid above a workspace, the workspace having a plurality of stacked containers. The system includes a series of robotic load handling devices operating on the grid above the workspace, the load handling devices having a body mounted on wheels. The robotic devices can move around the grid under instruction from a computing device, the robotic devices being moved to a point on the grid above a stack of containers and then, using a lifting device, engage and lift a container from the stack. The container is then moved to a point where the objects in the container can be accessed. Modifications to the workspace and grid are described that allow vehicles and roll cages to be used to move stacks from the workspace to a point outside the workspace or from outside the workspace into the workspace.

A system for reversibly dividing a space is disclosed. Independent panels, with track followers attached to both narrow sides, move along parallel tracks. The panels start in an overhead storage space. The tracks are shaped such that as the panels move from the storage space into the space to be divided, one panel stops higher and the next panel slides down and then under the first panel. These panels preferably form a single-plane divider in the space.
