A partition (10), mounted on a mounting surface, comprises a plurality of elongate upright members (16, 18), a first board (20) and a second board (22). The first board is mounted on one side of a pair of the elongate upright members that are adjacent to each other, and the second board is mounted on the other side of the same pair of adjacent elongate upright members, so as to provide a cavity (24) between the pair of elongate upright members and the first and second boards. The partition further comprises a spacer (26) that is located within the cavity, the maximum dimension of the spacer in the through-thickness direction of the partition being at least 90% of the separation of the two boards. The spacer may help to reduce the extent of inward bowing of the boards between adjacent elongate upright members, so that, for example, the upright members may be spaced further apart

A kit for assembling prefabricated wall panels includes prefabricated wall panels and clips. Each side of the prefabricated wall panels is configured to form a side-lap joint and at least a tongue and groove joint upon assembly. Each clip includes a flange having a plurality of holes and a web that is connected to an edge of the flange and is at least 4 inches long. The clips may allow for greater panel spans and/or provide improved wind resistance. For assembling the prefabricated wall panels to a building structure, a clip is placed on a cheek surface of the side-lap joint of one of the prefabricated wall panels. Fasteners are threaded through the prefabricated wall panel to clamp an edge of the prefabricated wall panel between the clip and the building structure.

An enclosure assembly apparatus can include a plurality of elements that can be arranged to facilitate positioning of an enclosure in a work space such as a room or floor of an office building or other building. Embodiments can be configured to facilitate relatively quick and level positioning of such an enclosure. Embodiments of the enclosure assembled via use of at least one embodiment of the enclosure assembly apparatus can be define a room, a meeting space, a privacy booth, a meeting cubicle, or other type of enclosure or work space within the room or floor of a building.

A background wall structure. The background wall structure includes an object placing plate and a fifth straight rod, where a four-way member is movably mounted at each of the two sides of the fifth straight rod; a first straight rod is movably mounted at the top of each four-way member; the object placing plate is fixedly mounted between the first straight rods; an object placing plate fixing block is fixedly mounted at one side of each first straight rod; a second straight rod is movably mounted at the top of each first straight rod. The bottom of the background wall structure adopts the four-way members, the first elbow pipe and the fifth straight rod which are connected to form a triangular base, so that the background wall structure is stable after assembling, and is convenient to disassemble.

A system comprising an inner cement wall board, an outer cement wall board, and a cement or concrete compatible adhesive formed between the fluid-applied water-resistive barrier and the outer cement wall board, wherein the cement or concrete compatible adhesive forms drainage channels between the inner cement wall board and the outer cement wall board.

A building system may include at least one diaphragm beam having opposite ends connected to an external structural frame of a building, at least one pre-assembled floor-ceiling panel adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall adjacent to a horizontal side of and coupled to the diaphragm beam. The diaphragm beam may be filled with a mineral-based material, such as concrete. The one or more pre-assembled floor-ceiling panels may each include a plurality of joists extending perpendicular to the diaphragm beam, a floor-panel including at least one metal layer attached to the joists on a floor side of the pre-assembled floor-ceiling panel, and a ceiling panel including at least one layer comprising mineral-based material attached to the joists on a ceiling side of the pre-assembled floor-ceiling panel. The one or more pre-assembled walls may include interior and/or exterior walls of a building.

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.

The invention relates to a dry construction system for making partition walls (1), suspended ceilings or the like, with a support structure (2), a cladding (3) arranged on at least one side of this, and an insulation layer (4), wherein the support structure (2) comprises a plurality of carrier profiles (22), to which at least one cladding (3) is secured, and wherein the carrier profiles (22) are formed from a sheet material and exhibit in cross-section a basic section and two limb sections arranged perpendicular thereto, and comprise an embossing with regularly distributed elevations and depressions. In this situation, the centre-to-centre distance between two adjacent elevations of the embossing on one side of the sheet material is less than six times the rated sheet thickness, and the base section is connected to the adjacent limb section in each case by a curved section with an outer radius which amounts to at least three times the rated sheet thickness. The invention further relates to a carrier profile (22) for such a dry construction system and uses of such a dry construction system. In this way a generic dry construction system is further improved in respect of the sound insulation properties.
