The invention relates to the construction industry. This invention can be used in the field of creating suspended planes and coverings. This invention may be used in the field of creating suspended ceilings of various designs. And the invention can also be used in the field of creating other similar suspended structures.
Structures that utilize suspended ceilings of various kinds are well known. These structures are widely used indoors. We are talking about suspended ceilings. Also, these structures are used in devices for a wide variety of purposes.
From the prior art, a ceiling covering attachment assembly to a wall is known. This attachment assembly includes a U-shaped profile member. A shelf of the profiled element adjoins the wall from the inside. The shelf of the profile element has a longitudinal groove. The attachment unit also includes a cage for installation within the profiled element. This embedded part in a cross section is made in the form of a triangle. One corner of the triangle is placed in the groove of the profile element. And the opposite to this corner facet is in contact with another vertical flange of the profiled element. The facet is in contact in the working position. See patent for a useful model of the Russian Federation No 37744, cl. IPC E043 7/10.
Disadvantage of the known profile is its limited functionality. As the profile is designed only for fastening the cloth stretch ceiling to the wall. And this profile is not applicable in the structures of the suspended ceiling.
Also known is a profile for installing a suspended ceiling. This profile is formed by two mutually perpendicular shelves. Also, this profile is formed by a lintel that is attached to one of the shelves. This lintel is parallel to the other shelf. And this bridge is wider than the other flange (patent RU 16605 U1, cl. IPC E043 9/18).
The disadvantage of the known profile for suspended ceilings can be attributed to the narrow functionality. Since the known profile provides a rigid attachment of ceiling panels to the ceiling frame and supporting surfaces. The rigid mounting design of the suspended ceiling panels to the supporting surfaces contributes to the increasing tensile stresses. This occurs during use. This is due to changes in the geometry of the walls and mating surfaces. And leads to warping and destruction.
As the closest technical solution of the claimed useful model, a ceiling profile is selected. This profile is used for the installation of stretch and suspended ceilings. This profile contains a first and a second shelf. In the end stepped part of the first shelf is a groove. The depth of the groove is more than half the thickness of the first shelf. The first flange is connected to the second flange by two partitions to form a channel. The stepped part of the first shelf is provided with an additional cantilever shelf. The cantilevered shelf is located to the outside. And there is a cantilever shelf on the inner side of the second shelf (patent RU 182821 U1, IPC E04B 9/30).
The disadvantage of the closest analogue, as well as other known analogues, is its low reliability. Low reliability is associated with possible damage to the ceiling fabric. For example, the canvas, which is made of gypsum board (CBC) and its analogs. Analogues assume, as in solution RU 16605, rigid attachment of the sheet to the wall surface. Fastening the sheet with metal profiles. The walls of apartments and houses are inevitably subject to changes in geometry. This is especially true for new houses during the initial shrinkage of the building. Also on short-term changes in geometry influence temperature changes, repairs, etc. Changing the geometry of the walls when the ceiling profile is rigidly fixed is accompanied by an increase in the ceiling plane. Increase of the plane due to the different heights of the walls. This situation leads to tensile stresses. As a consequence, cracks in the gypsum plaster and plaster.
This problem also applies to other joints. Wall-wall, wall-floor, door frame-wall. As well as any other adjoining surfaces with variable geometry. In addition to changing the size of the ceiling space, the angle between the assembled ceiling and the horizontal normal changes. This results in additional stresses on the fixings. As a result of these factors, classic suspended ceiling systems require a complete replacement of the suspended ceiling system. This includes the counterparts discussed above. And/or suspended ceiling systems require replacement and/or devices to attach them to supporting surfaces. And/or suspended ceiling systems require repair.
