Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 16/762,567 filed Oct. 25, 2018, which is the United States national phase of International Application No. PCT/EP2018/000488 filed Oct. 25, 2018, and claims priority to International Application No. PCT/EP2017/001315 filed Nov. 13, 2017, the disclosures of which are hereby incorporated by reference in their entirety. BACKGROUND OF THE INVENTION Field of the Invention 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. Description of Related Art So-called sliding ceiling connections are known in drywall construction. A connecting element for a sliding ceiling connection is disclosed for example in U.S. Pat. No. 5,040,345. The connecting element from the aforementioned publication has substantially a U-shape which can be inserted by one of its end sides, which shows the U-shape cross section, into a U-profile-shaped ceiling profile up to its U-profile web, that is to say against the ceiling, with the result that the U-profile-shaped connecting element is arranged transversely and thus perpendicularly to the U-profile-shaped ceiling profile. The upper end of a vertical stud of a stud frame of a drywall can be pushed onto the U shape of the connecting element in a sliding manner, or the U shape can be introduced into the upper end of the stud in a sliding manner. The free outermost end portions of the U-flanges of the U-profile of the connecting element can be screwed to the U-flanges of the ceiling profile, with the result that it is secured against a horizontal displacement in the ceiling profile. By contrast, the downwardly pointing width of the U-flanges of the connecting element predetermines a vertical sliding path for the upper end of the stud, which end can thus move correspondingly far from the U-web of the ceiling profile without coming completely free of the connecting element in the downward direction. In addition, for positive sliding guidance of the stud profile, the U-flanges of the connecting element have guide paths which are embodied as beads and in which the free longitudinal edges of a C-profile shape of the stud can engage in a positive manner. This positive engagement thus also prevents a horizontal movement of the stud, while it further allows a vertical movement. For the case of ceiling sag or upward bending, connecting elements are used as so-called sliding ceiling connections in order, with the help thereof, to connect ceiling profiles to stud profiles in such a way that a vertical movement and change of spacing between the upper ends of the studs and the ceiling profiles can be allowed and tolerated. At the same time or thereby the connection between the studs and the ceiling profiles being prevented from being completely released and the studs no longer being fixed in the horizontal direction by their upper ends, which would result in an instability of the wall. Deflections of ceiling profiles and/or stud profiles can occur particularly in the event of fire with a large action of heat or in the case of shocks, for example earth tremors or other jolts, that is to say dynamically. In such cases, a secure connection between ceiling and wall should remain to avoid adverse effects or even injuries to persons and, in the event of fire, to prevent fire spreading as long as possible. The sliding movement made possible by the connection means that the upper free end of the guided stud can be situated at a greater or lesser distance from the ceiling. To form a drywall, the stud is usually panelled with panelling boards in one layer or two layers on one or on both sides. These boards can preferably contain gypsum as a constituent part, which can in particular also be suited for a fire protection. Especially for a fire situation, a sliding ceiling connection can indeed also be provided. However, if then the distance between the upper free end of the stud and the celling profile increases as a result of the sliding ceiling connection, the distance between the upper free edges of the panelling boards fastened to the stud and the ceiling also increases. This can result in an air-permeable gap which breaches the desired fire protection and, as a “weak point”, facilitates and accelerates the transfer of fire. A similar problem also arises if the drywall and its panelling boards are provided for noise protection since, hereto, a gap between the ceiling and panelling boards can also breach the desired noise protection. The object on which the invention is based is therefore to propose a profile of the generic type mentioned at the outset that can accommodate a possible relative movement of components of a dryw
