Abstract

Claims (23)

1 . A component for a drywall construction arrangement, the drywall construction arrangement having a ceiling and at least one wall, comprising:

a profile, the profile having a cross section, the cross section having a substantially U-shape which comprises a web and two adjoining resilient flanges, the web having a width and a surface, the surface being configured to fixedly attach to the ceiling;

wherein the resilient flanges are each designed to be resilient to the same degree and/or in the same manner in a direction which is substantially orthogonal to the surface of the web; and

the resilient flanges each including a first linear portion proximate to the web and a second linear portion distal from the web, wherein at least one bead, being a substantially V-shaped bead, is intermediate to the first linear portion and the second linear portion, the second linear portion being longer in a length than the at least one substantially V-shaped bead, the length being along the direction which is substantially orthogonal to the surface of the web, the length of the at least one substantially V-shaped bead and the second linear portion having a ratio of approximately 2:3, the first linear portions and the second linear portions of the resilient flanges attach to the at least one wall preventing air passage between the at least one wall and the ceiling,

the at least one substantially V-shaped bead extends into an interior of the profile and comprises areas of material weakening in a form of recess bands, the areas of material weakening are along all three kinks forming the respective at least one substantially V-shaped bead.

2 . The profile according to claim 1 , wherein the respective beads are formed substantially as an arcuate recessing of a material of the respective resilient flange into the interior of the profile.

3 . The profile according to claim 1 , wherein the respective beads are formed such that the first linear portion and the second linear portion are equal in length.

4 . The profile according to claim 1 , wherein an effective flange length, the effective flange length being the length of each resilient flange extending from the web and including the length of the respective beads, and a length of each flange before incorporation of the respective beads have a ratio of approximately 3:4.

5 . The profile according to claim 1 , wherein the profile being provided as a ceiling profile for direct mounting on the ceiling.

6 . The profile according to claim 5 , wherein the ceiling profile is configured for a ceiling-side fastening of a drywall.

7 . The profile according to claim 6 , wherein the drywall comprises a panelled stud frame.

8 . The profile according to claim 1 , wherein the profile being provided as a connecting member for fastening a facing shell.

9 . A construction element set for a drywall comprising a panelled stud frame including a component according to claim 1 .

10 . The construction element set according to claim 9 , wherein the web of the at least one profile being provided for connection to the ceiling, the at least one wall or a floor and for fastening at least one panelling board to at least one of the resilient flanges, wherein the at least one of the resilient flanges blocks off a gap region between a free edge of the panelling board and the ceiling, the wall or the floor to prevent air passage.

11 . The construction element set according to claim 10 , wherein the web of the at least one of the first profile or second profile is being lined on the ceiling, the at least one wall or floor with at least one strip of the at least one panelling board.

12 . The construction element set according to claim 10 , wherein a fastening of the at least one panelling board to the at least one of the resilient flanges is being provided with an overhang of the at least one panelling board that projects in a direction of the web.

13 . A drywall, the drywall being fastened to the construction element set according to claim 9 .

14 . A profile for a ceiling-, floor- or wall-side fastening of a drywall comprising: a panelled stud frame, wherein the profile has a first profile and a second profile each having, a cross section, in the cross section a substantially U-shape which comprises a web and two adjoining resilient flanges, wherein the resilient flanges are each designed to be resilient to the same degree and/or in the same manner in a direction which is substantially orthogonal to a surface of the web, the resilient flanges each having a bead, and

wherein the profile has a substantially box-shaped cross section by being formed from the first profile and the second profile, which the first profile and the second profile are nested with one another in such a way that the first profile and the second profile are pushed into one another with each of the resilient flanges leading and a portion of each of the resilient flanges are in between the beads of the first profile and the second profile,

wherein each of the resilient flanges have a first linear portion proximate to the web and a second linear portion distal from the web and wherein each of the beads are intermediate the second linear portions and the first linear portions and the second linear portions overlap when nested with another profile, and the first linear portions and the second linear portions of the resilient flanges attach to at least one wall preventing air passage between the at least one wall and a ceiling.

15 . A component for a drywall construction arrangement, comprising: a first profile and a second profile each having a cross section, the cross section having a substantially U-shape, the first profile and the second profile form a substantially box-shaped cross section when the first profile and the second profile are nested, the first profile and the second profile each comprise a web and two adjoining resilient flanges, wherein the two resilient flanges are designed to be resilient to the same degree and/or in the same manner in a direction which is substantially orthogonal to a surface of the web, and the two resilient flanges each including a first linear portion proximate to the web and a second linear portion distal from the web, wherein at least one bead is intermediate to the first linear portion and the second linear portion, each of the at least one beads extending longitudinally substantially parallel to a web extent comprising one or more areas of material weakening in a form of one or more recess bands, the one or more areas of material weakening along one or more kinks forming the at least one beads, and

wherein when the first profile and the second profile are nested, the first and second profiles are pushed into one another with each of the resilient flanges leading, and in between each of the beads the second linear portions of the resilient flanges of the first and second profiles contact one another, the resilient flanges and the beads directly face one another and towards an interior of the substantially box-shaped cross section,

wherein the first linear portion and the second linear portion of the resilient flanges attach to at least one wall preventing air passage between the at least one wall and a ceiling.
