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 invention relates to a modular wall system comprising a number of mutually releasably couplable wall modules for forming in coupled state a reusable assembled wall, wherein a wall module comprises a wall part with attaching means for releasably attaching at least an exchangeable cloth along at least one side of the wall part, wherein the attaching means comprise: at least a first cloth attaching element arranged close to or on a first outer end of the wall part; at least a second cloth attaching element arranged close to or on a second, opposite outer end of the wall part; an exchangeable cloth to be attached along the at least one side of the wall part to the first and second attaching element mounted on the wall part for the purpose of providing a desired appearance on the relevant side of the wall part.

A partition wall has a structure with a wall end portion butted against another building structure and exposed to architectural spaces. An end post at the end portion of the wall is constituted from first and second end post elements, which are spaced apart from each other, so that a gap or an isolation zone interrupting a propagation of a solid vibration or insulating a path for propagating the solid vibration is formed between the first and second elements. An interior finishing panel for defining the architectural space on one side of the wall is fixed to the first element and the interior finishing panel for defining the architectural space on an opposite side of the wall is fixed to the second element.

A smart wall comprises: a frame structure including a mounting cell; an electronic product disposed in the mounting cell; and an art wall covering the front of the frame structure, wherein the frame structure comprises: a first steel section; a second steel section which includes a second fastening part formed at the end thereof and is disposed in a direction perpendicular to the first steel section; a first fastening part which includes multiple first fastening holes arranged in the width direction of the first steel section; the second fastening part which is located at the end of the second steel section and includes multiple second fastening holes corresponding to the multiple first fastening holes; and fastening screws passing through the first fastening part and the second fastening part, and the first fastening part comprises multiple first fastening parts disposed at predetermined intervals in the extension direction of the first steel section. Accordingly, various frame structures can be implemented and thus reduced manufacturing costs can be achieved.

Provided are a heat-insulating and sound-absorbing material improved in construction workability, and a partition wall in which degradation in sound insulation performance is suppressed. The heat-insulating and sound-absorbing material 1 is comprised of an agglomerate of inorganic fibers, wherein the agglomerate has a density of 10 to 20 kg/m.sup.3 and the inorganic fibers of the agglomerate have a length-weighted average fiber diameter of 2.0 to 8.7 μm, and wherein the agglomerate contains: 20 to 66% of inorganic fibers having a length-weighted average fiber diameter of less than 4.0 μm; and 13 to 58% of inorganic fibers having a length-weighted average fiber diameter of 7.0 μm or more. The partition wall comprises a hollow wall portion, and the above heat-insulating and sound-absorbing material installed in the hollow wall portion.

Certain exemplary embodiments can provide a wall frame comprising a top plate, a bottom plate, a first end column, a second end column, a plurality of studs, and a plurality of purlins. Each of the plurality of purlins is an edge of a pair of cells, the pair of cells having edges comprising three edges that comprise one or more of a part of the top plate, a part of the bottom plate, a part of the first end column, a part of the second end column, a part of the plurality of studs, and another of the plurality of purlins.

The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.
