A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when contacted by water via dissolution, melting or through some other destructive process initiated by contact with water. Some or all of the materials comprising the protective barrier can be designed to fail at a certain temperature. This failure can create access points from the ceiling through the protective barrier to the area being protected by the barrier, which can allow water from a fire suppression system to reach a fire located below the protective barrier.

A mounting profile for lighting system of suspended ceiling, which comprises a comprehensive triple-section aluminium profile, where repositionable wireless luminaires fitted with magnets can be used on the mounting profile and comprises devices for fastening stretch ceiling material as well as other types of suspended ceiling materials thereto.

An acoustic insulated ceiling system is disclosed. The system comprises a first profile and a second profile. The system comprises a carrier layer connected to the first profile and the second profile. As such the carrier layer is suspended between the first profile and the second profile. The system comprises a bottom layer in a high density material. The bottom layer supports on the carrier layer. The bottom layer extends from the first profile to the second profile. The system comprises an intermediate layer in a low density insulation material. The intermediate layer supports on the bottom layer. The system comprises a top layer in a high density material. The top layer supports on the intermediate layer. The top layer extends from the first profile to the second profile.

The fabric mounting system (1) includes a mounting profile (4) adapted to be mounted to a wall or ceiling and at least one fabric retaining element (5) engaging the mounting profile and being adapted to retain an edge (6) of the fabric (2). First and second supporting faces (9, 10) of the mounting profile (4) are mutually tapered in such a tapering direction (T) that a resilient bias of first and second legs (7, 8) of the fabric retaining element (5) urges the first and second legs (7, 8) to slide along the first and the second supporting faces (9, 10), respectively, to thereby displace the fabric retaining element in a direction generally against the tapering direction (T) and in a fabric tensioning direction (F) being transverse to a longitudinal direction (L) of the mounting profile (4) in order to stretch the fabric (2) in its retained position.

A double rail (1) for creating a stretched-fabric structure, having a tubular body comprises a longitudinal passage opening (3) for the passage of stretched fabrics, wherein the tubular body comprises two internal flanges (4, 5) converging toward one another and delimiting, with an internal wall (6), a cavity (7) in which lighting means (8) are housed, the cavity (7) being open toward the passage opening (3).

A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when contacted by water via dissolution, melting or through some other destructive process initiated by contact with water. Some or all of the materials comprising the protective barrier can be designed to fail at a certain temperature. This failure can create access points from the ceiling through the protective barrier to the area being protected by the barrier, which can allow water from a fire suppression system to reach a fire located below the protective barrier.

The panel includes a frame formed by profile members (6) and a plate member (10) extending therebetween. A textile (11) extends between the profile members which are formed by bending an edge area of a metal plate (15) forming the plate member (10), thereby forming said profile members in one piece with the plate member. Said edge area forms a rounded edge (16) connecting the plate member with the profile member. The profile member includes a first oblique section (21) of the metal plate forming an acute angle with the plate member and having a first end being connected to the rounded edge. The textile is bent about the rounded edge, and an edge element (24) attached along an edge (12) of the textile is adapted to slide along the first oblique section and is spring-biased in the direction of a second end (23) of the first oblique section.

A ribband for a stretched fabric three-dimensional structure comprising at least one light source incorporated in the ribband, wherein the ribband comprises two adjacent recesses separated by a tongue designed to receive the fastening elements of the stretched fabrics, wherein each recess comprises a bottom, an inner side wall forming the tongue and an outer side wall, wherein each outer side wall defines a peripheral wing of the ribband.

A system for influencing the senses of a person in a room for measuring and/or influencing physiological parameters of the person is provided. The person is substantially stationary and lying in the room during the measurement and/or influencing. The system includes a sound insulating apparatus for screening off acoustically active devices with respect to the person. The acoustically active devices serve for measuring and/or influencing the physiological parameters in the room, and an optical display apparatus for offering optical stimuli and/or signals for the person in the field of view of the person.

The invention relates to the construction industry and can be used in the field of creating suspended surfaces and coverings, in particular suspended ceilings of varying design, and also other analogous suspended structures.

The technical result which can be achieved with the use of the invention consists in increasing the reliability of a coupling assembly of a device for fastening a suspended ceiling or other analogous suspended coverings.

The technical result is achieved using a coupling assembly of a device for fastening a suspended ceiling, which comprises the following parts interconnected by mating connecting elements of a lock connection: a supporting part with an installation means having a supporting surface, and a mounting part having a means for connection to a surface of panels of the suspended ceiling, wherein the lock connection is designed to be shock-absorbing and consists of two mating parts provided with mating connecting elements formed on the connectable mating and mounting parts, where one of the mating parts is provided with a C-shaped profile with an open cavity and, mounted therein, a damper which is provided with an element for anchoring the mating element of the lock connection situated on the other part of the coupling assembly.
