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.

Techniques for and examples of a partition wall structure of a building are described, including a first shell formed as a first wythe including a first group of stacked elongated beads of extruded building material, a second shell spaced apart from the first shell and formed as a second wythe that has a second group of stacked elongated beads of extruded building material, and at least one structural support having a first portion embedded in the first wythe, and a second portion embedded in the second wythe.

The invention(s) disclosed herein include(s) various panels, components of panels, partitions, systems, and/or methods that increase acoustic insulation. For example, some embodiments include a movable partition where the interface between two panels includes various gaskets, damping elements, and/or perforations that mitigate sound transmission from one side of the partition to the other. In one or more embodiments, the partition and/or panel(s) include one or more upper and/or lower drops seals having a gasket that significantly impedes sound from entering a window associated with the panel(s), which in some embodiments leads to a cavity/region relative to which the drop seal is retractable/extendable.

The invention relates to a profile for arranging a component for a drywall construction, in particular a profile for a preferably ceiling-side fastening of a drywall, preferably a profile for a drywall comprising a panelled stud frame. Furthermore, the invention relates to a construction element set and to a drywall having such a profile. The invention provides a profile of the aforementioned generic type that can accommodate a possible relative movement of components of a drywall construction in an improved manner. This object is achieved according to the invention in that the profile has, in its cross section, substantially a U shape which comprises a web and two adjoining flanges, wherein the flanges are each designed to be resilient to the same degree and/or in the same manner in the direction which is substantially orthogonal to the web surface.

A system for the partition of a space that has a ceiling includes at least one partition wall that partitions the space and has at least one planar element and a system connecting it to the ceiling. Such system and the upper peripheral edge of the planar element include male and female elements. The connecting system further includes at least one elastomeric element interposed between the female and the male elements, which deforms upon the coupling of the male and female elements and frictionally acts against them to prevent the planar element from falling down by gravity, without the need for additional support in the lower part of the planar element.

A wall element having two sets of columns with panel between the columns so that the columns of the first set and the second set are within each other so that the wall element can be extended and contracted, depending on the room height, in such a way that the wall panels cover the area between columns and form a substantially continuous wall from floor to ceiling.

A moveable wall is connected to a structure and is operable to receive power from a power source. The moveable wall includes a first panel is connected to the structure for movement with respect to the structure. The first panel has a first electrical connection and the first panel receives power from the power source and to direct said power to the first electrical connection. A second panel is connected to the structure for movement with respect to the structure. The second panel has a second electrical connection, and the second electrical connection is configured to electrically connect to the first electrical connection to receive said power from the first electrical connection. One of the first electrical connection and the second electrical connection has a degree of freedom to move relative to the respective panel.

A seismic protective structure (100) for forming part of a board partition (190) and for limiting damage to the board partition (190) when a given level of seismic stress is appearing is described. The seismic protective structure (100) comprises at least one board (101) and support elements (102, 103) for positioning the board adjacent a neighboring wall and linking the board to the remainder of the board partition wall. The seismic protective structure (100) is adapted for, when a given level of seismic stress is appearing, intentionally causing damage of the at least one board (101) thereby releasing pressure from the remainder of the board partition(190).

A wall element having two sets of columns with panel between the columns so that the columns of the first set and the second set are within each other so that the wall element can be extended and contracted, depending on the room height, in such a way that the wall panels cover the area between columns and form a substantially continuous wall from floor to ceiling.
