Definitions

  • the invention relates to a hanger for dry construction, comprising a body which has a first portion for connection to the building and a second portion for connection to a C-profile which has a profile web and a first profile flange having a first bearing bar and a second profile flange having a second bearing bar.
  • the invention also relates to a dry construction arrangement having such a hanger.
  • Hangers of this type are used in dry construction in particular for the creation of suspended ceilings.
  • C-profiles are attached to a building component, in particular in a hanging manner, using the hangers.
  • Ceiling cladding can then be attached to the C-profiles. In this way, a suspended ceiling construction can be created.
  • the object of the invention is to further develop a hanger for dry construction and a dry construction arrangement in such a way that these can absorb a high load and at the same time are easy to assemble.
  • a hanger for dry construction comprising a body which has a first portion for connection to the building and a second portion for connection to a C-profile which has a profile web and a first
  • CONFIRMATION COPY profile flange having a first bearing bar and a second profile flange having a second bearing bar
  • the second portion has a first bearing portion for resting against an underside of the first bearing bar and a second bearing portion for resting against an underside of the second bearing bar
  • the second portion has a first holding portion for resting against an upper side of the first bearing bar
  • the body has, on a first side, a first main surface pointing in a first direction, and has, on a second side, a second main surface pointing in a second direction
  • a first support portion having a first side surface is arranged on the first bearing portion for resting against an inner side of the first profile flange
  • a second support portion having a second side surface is arranged on the second bearing portion for resting against an inner side of the second profile flange
  • the second portion has a width (B) in the region of the support portions, wherein the first and the second support portions point from the second portion in the first direction.
  • This design allows a stable fastening of a C-profile to a building component. Therefore, stable suspended ceilings can be produced in particular using the hanger.
  • the weight of the suspended ceiling can be transferred to the hanger via the C-profile, in that the first and the second bearing portions rest against the undersides of the first and the second bearing bars.
  • the hanger is particularly easy to assemble. It allows reliable and safe creation of suspended ceilings, reducing the risk of incorrect assembly. This is also achieved by the fact that the hanger does not require any safety elements that have to be bent manually after the hanger has been inserted into the C-profile in order to obtain a secure attachment.
  • the hanger contributes to quick assembly, so that assembly times are reduced.
  • the hanger can be produced inexpensively and therefore also contributes to a cost reduction.
  • the material thickness of the hanger can be reduced with the same load capacity, thus saving material. Since the first and the second support portions, starting from the second portion, point in the same direction, namely the first direction, a particularly stable connection between the hanger and the C-profile can be achieved. This is also attributed to the fact that the hanger is supported on the inner sides of the profile flanges of the C-profile with support surfaces that lie opposite one another in relation to a central longitudinal axis of the C-profile.
  • first and the second support portions each have a free end, wherein the free ends of the first and the second support portions point in the first direction. Furthermore, it is preferred according to the invention that the first and the second support portions are each connected to the second portion via a bent region. This contributes to high stability and allows simple production.
  • a particularly preferred embodiment of the invention provides that the first support portion is connected to the second portion via a first bending line, and the second support portion is connected to the second portion via a second bending line.
  • the first support portion in a direction perpendicular to the first bending line and the second support portion in a direction perpendicular to the second bending line each have a support portion length which is between 5% and 20% of the width B of the second portion. This contributes to high stability and at the same time allows easy assembly.
  • the hanger can be connected to the C-profile by screwing it in.
  • a preferred embodiment provides that the first support portion in a direction parallel to the first bending line and the second support portion in a direction parallel to the second bending line each have a support portion height which is between 30% and 40% of the width B of the second portion. This also contributes to high stability and enables easy assembly.
  • the second portion forms a main plane and the first and the second support portions are each arranged at right angles to the main plane.
  • the first and the second side surfaces can be arranged parallel to the inner sides of the first and the second profile flanges, which contributes to good stability.
  • due to the orientation of the second portion perpendicular to the first and the second profile flanges a particularly high level of stability is achieved.
  • first and the second support portions are arranged in a vertical plane in the installed position.
  • a particularly preferred embodiment of the invention provides that the second portion has a second holding portion for resting against an upper side of the second bearing bar. This contributes to further improved stability. Furthermore, it can advantageously be provided that the first holding portion points from the second portion in the second direction. A design is thus realized in which the support portions and the first holding portion point in opposite directions. This contributes to high stability and easy assembly. Preferably, the second holding portion points from the second portion in the second direction.
  • the first holding portion has a free end pointing in the second direction.
  • the second holding portion has a free end pointing in the second direction.
  • a further improvement can be achieved if a space for receiving the first bearing bar is formed between the first holding portion and the first bearing portion. Furthermore, it can be provided that a space for receiving the second bearing bar is formed between the second holding portion and the second bearing portion.
  • first holding portion is designed as a first bent flap.
  • the second holding portion is preferably designed as a second bent flap.
  • the first and the second flaps are planar. In the case of this configuration, it can be achieved that the first and, if necessary, the second holding portion rest only against the upper sides of the first and the second bearing portions.
  • first holding portion is designed to be arranged completely above the first bearing portion in the assembled state.
  • the second holding portion is preferably designed to be arranged completely above the second bearing portion in the assembled state.
  • first and second holding portions are formed which do not rest against the outer sides of the first and the second profile flanges. This makes assembly easier, as the hangers can be obliquely inserted into the C-profile and then positively connected to the C-profile by turning the hanger.
  • the hanger is clamped in the profile so that the hanger remains in the intended position during the assembly of the profile and does not slip out or tilt.
  • a preferred embodiment of the invention provides that the first holding portion is designed to rest under prestress against the upper side of the first bearing bar.
  • the second holding portion is also designed to rest under prestress against the upper side of the second bearing bar. This achieves a particularly secure connection between the hanger and the C- profile, with rattling being avoided in particular.
  • the prestressing can be achieved in particular by the second portion forming a main plane and the first holding portion being arranged at an angle of between 80° and 89° (preferably between 86° and 88°) to the main plane of the second portion.
  • the region of the second portion lying outside of the beads forms the main plane.
  • a particularly advantageous embodiment of the invention provides that the first holding portion is formed by a first bent region of the second portion.
  • the second holding portion is preferably formed by a second bent region of the second portion. This contributes to high stability and low production costs.
  • a preferred embodiment of the invention provides that the hanger has a width B' in the region of the first and the second holding portions, the width B' being between 100% and 110% of the width B.
  • the width B' is between 101% and 108% of the width B.
  • the first holding portion has a closed surface and/or a closed peripheral contour.
  • the first holding portion has no recesses or holes in the interior of the holding portion or in the peripheral contour.
  • a second holding portion it can have the same feature. This achieves increased stability against bending. In this way it can be achieved that the first and the second holding portions rest only against the desired region of the C-profile (in this case the upper side of the first and the second bearing bars).
  • a further preferred embodiment of the invention provides that the first holding portion is connected to the second portion via a third bending line. It can furthermore be provided that the second holding portion is connected to the second portion via a fourth bending line. This contributes in particular to good stability and low production costs.
  • the first holding portion has a holding portion length in a direction perpendicular to the third bending line, which holding portion length is between 5% and 30% (preferably more than 10%, preferably less than 25%) of the width B of the second portion.
  • the second holding portion has a holding portion length in a direction perpendicular to the fourth bending line, which holding portion length is between 5% and 30% (preferably more than 10%, preferably less than 25%) of the width B of the second portion.
  • a further preferred embodiment provides that the first holding portion has a holding portion width in a direction parallel to the third bending line, which holding portion width is between 10% and 25% of the width B of the second portion. It can furthermore be provided that the second holding portion has a holding portion width in a direction parallel to the fourth bending line, which holding portion width is between 10% and 25% of the width B of the second portion.
  • the edge of the first recess is formed obliquely, so that the first bearing edge is inclined towards the middle of the second portion.
  • the edge of the second recess is formed obliquely, so that the second bearing edge is inclined towards the middle of the second portion.
  • the first bearing edge preferably comprises an inclined straight portion which extends over at least 50% of the bearing edge.
  • the inclination of the bearing edge preferably runs from the top outside to the bottom inside, relative to the second portion. This bevel allows the bearing bar(s) to snap into the recess(es) of the second portion.
  • the sheet metal thickness is between 0.4 mm and 1 .2 mm.
  • the sheet metal thickness is preferably between 0.6 mm and 0.8 mm.
  • the body having the first and the second portions as well as the first and the second support portions and the first holding portion is produced by forming (preferably bending) from a single piece of sheet metal. If the body also has a second holding portion, this can also be produced by forming from the same piece of sheet metal.
  • the piece of sheet metal is preferably processed by a separating method (particularly dividing, such as punching, for example) before forming.
  • first portion and/or the second portion have reinforcing beads.
  • Reinforcing beads are preferably provided, which extend continuously from the second portion into the first support portion and/or the second support portion.
  • the stability is further improved if the beads are designed in such a way that they protrude towards the inner side of the first or second support portion. In this way, a level contact of the first and the second support portions on the inner side of the profile flange is achieved, which ensures good force transmission.
  • the first portion has connecting means for connection to the building.
  • the connecting means can be arranged on the first or the second main surface of the body. A particularly good stability is achieved when the connecting means are arranged on the second main surface.
  • the connecting means comprise a connecting portion with a plurality of holes arranged one below the other in a row.
  • the distances between the holes are preferably the same.
  • the holes can in particular form so-called vernier perforations or nonius perforations.
  • the holes arranged in this way make it possible to arrange the hanger at different height positions relative to an upper part of the hanger and to fix it with push-through elements.
  • the upper part of the hanger can also have a row of holes which are arranged to correspond to the holes in the hanger.
  • the first direction is opposite to the second direction.
  • a preferred embodiment provides that the width B of the second portion is between 95% and 105% (preferably between 99% and 101%) of the distance between the first and the second profile flanges before assembly.
  • an intermediate space is formed between the hanger and the profile web, so that the hanger does not touch the profile web. Resting against the profile web is also not necessary, since good force transmission is already achieved with the bearing portions, the support portions, and the holding portions, whereby rattling can be avoided.
  • the object on which the invention is based is also achieved with a method for producing a suspended ceiling.
  • the method provides that a C-profile, which has a profile web and a first profile flange having a first bearing bar and a second profile flange having a second bearing bar, is attached to a part of a building using a hanger described above.

Description

Hangers for dry construction as well as dry construction arrangement having such a hanger
The invention relates to a hanger for dry construction, comprising a body which has a first portion for connection to the building and a second portion for connection to a C-profile which has a profile web and a first profile flange having a first bearing bar and a second profile flange having a second bearing bar. The invention also relates to a dry construction arrangement having such a hanger.
Hangers of this type are used in dry construction in particular for the creation of suspended ceilings. In this case, C-profiles are attached to a building component, in particular in a hanging manner, using the hangers. Ceiling cladding can then be attached to the C-profiles. In this way, a suspended ceiling construction can be created.
DE 202016 102338 U1 describes a hanger for a C-profile having two support portions pointing in opposite directions. Furthermore, the previously known profile comprises portions which are brought into contact with the outer sides of the profile flanges of the C-profile by bending.
DE 91 05466 U1 describes a hanger for a C-profile which has curved portions which lie against the outer side of the profile flanges of the C-profile.
DE 202007010881 U1 , DE 201 16627 U1 , and DE 297 19 610 U1 describe hangers for dry construction, in which the hanger is clamped to the C-profile using a clamping element.
The object of the invention is to further develop a hanger for dry construction and a dry construction arrangement in such a way that these can absorb a high load and at the same time are easy to assemble.
This object is achieved by a hanger having the features of claim 1. Accordingly, a hanger for dry construction is provided, comprising a body which has a first portion for connection to the building and a second portion for connection to a C-profile which has a profile web and a first
CONFIRMATION COPY profile flange having a first bearing bar and a second profile flange having a second bearing bar, wherein the second portion has a first bearing portion for resting against an underside of the first bearing bar and a second bearing portion for resting against an underside of the second bearing bar, wherein the second portion has a first holding portion for resting against an upper side of the first bearing bar, wherein the body has, on a first side, a first main surface pointing in a first direction, and has, on a second side, a second main surface pointing in a second direction, wherein a first support portion having a first side surface is arranged on the first bearing portion for resting against an inner side of the first profile flange, and a second support portion having a second side surface is arranged on the second bearing portion for resting against an inner side of the second profile flange, wherein the second portion has a width (B) in the region of the support portions, wherein the first and the second support portions point from the second portion in the first direction.
This design allows a stable fastening of a C-profile to a building component. Therefore, stable suspended ceilings can be produced in particular using the hanger. The weight of the suspended ceiling can be transferred to the hanger via the C-profile, in that the first and the second bearing portions rest against the undersides of the first and the second bearing bars. The hanger is particularly easy to assemble. It allows reliable and safe creation of suspended ceilings, reducing the risk of incorrect assembly. This is also achieved by the fact that the hanger does not require any safety elements that have to be bent manually after the hanger has been inserted into the C-profile in order to obtain a secure attachment. The hanger contributes to quick assembly, so that assembly times are reduced. The hanger can be produced inexpensively and therefore also contributes to a cost reduction. Due to its stability, the material thickness of the hanger can be reduced with the same load capacity, thus saving material. Since the first and the second support portions, starting from the second portion, point in the same direction, namely the first direction, a particularly stable connection between the hanger and the C-profile can be achieved. This is also attributed to the fact that the hanger is supported on the inner sides of the profile flanges of the C-profile with support surfaces that lie opposite one another in relation to a central longitudinal axis of the C-profile.
An advantageous embodiment of the invention provides that the first and the second support portions each have a free end, wherein the free ends of the first and the second support portions point in the first direction. Furthermore, it is preferred according to the invention that the first and the second support portions are each connected to the second portion via a bent region. This contributes to high stability and allows simple production.
A particularly preferred embodiment of the invention provides that the first support portion is connected to the second portion via a first bending line, and the second support portion is connected to the second portion via a second bending line.
According to the invention, it is preferred that the first support portion in a direction perpendicular to the first bending line and the second support portion in a direction perpendicular to the second bending line each have a support portion length which is between 5% and 20% of the width B of the second portion. This contributes to high stability and at the same time allows easy assembly. In particular, the hanger can be connected to the C-profile by screwing it in.
A preferred embodiment provides that the first support portion in a direction parallel to the first bending line and the second support portion in a direction parallel to the second bending line each have a support portion height which is between 30% and 40% of the width B of the second portion. This also contributes to high stability and enables easy assembly.
According to a preferred embodiment, it is provided that the second portion forms a main plane and the first and the second support portions are each arranged at right angles to the main plane. In this way, the first and the second side surfaces can be arranged parallel to the inner sides of the first and the second profile flanges, which contributes to good stability. In addition, due to the orientation of the second portion perpendicular to the first and the second profile flanges, a particularly high level of stability is achieved.
According to the invention, it can also be provided that the first and the second support portions (apart from beads that may be provided) are arranged in a vertical plane in the installed position.
A particularly preferred embodiment of the invention provides that the second portion has a second holding portion for resting against an upper side of the second bearing bar. This contributes to further improved stability. Furthermore, it can advantageously be provided that the first holding portion points from the second portion in the second direction. A design is thus realized in which the support portions and the first holding portion point in opposite directions. This contributes to high stability and easy assembly. Preferably, the second holding portion points from the second portion in the second direction.
It can be provided in a preferred manner that the first holding portion has a free end pointing in the second direction. Preferably, the second holding portion has a free end pointing in the second direction.
A further improvement can be achieved if a space for receiving the first bearing bar is formed between the first holding portion and the first bearing portion. Furthermore, it can be provided that a space for receiving the second bearing bar is formed between the second holding portion and the second bearing portion.
A preferred embodiment provides that the first holding portion is designed as a first bent flap. The second holding portion is preferably designed as a second bent flap. Preferably, the first and the second flaps are planar. In the case of this configuration, it can be achieved that the first and, if necessary, the second holding portion rest only against the upper sides of the first and the second bearing portions.
It can be provided in an advantageous manner that the first holding portion is designed to be arranged completely above the first bearing portion in the assembled state. The second holding portion is preferably designed to be arranged completely above the second bearing portion in the assembled state. In this way, first and second holding portions are formed which do not rest against the outer sides of the first and the second profile flanges. This makes assembly easier, as the hangers can be obliquely inserted into the C-profile and then positively connected to the C-profile by turning the hanger. In addition, the hanger is clamped in the profile so that the hanger remains in the intended position during the assembly of the profile and does not slip out or tilt.
A preferred embodiment of the invention provides that the first holding portion is designed to rest under prestress against the upper side of the first bearing bar. Preferably, the second holding portion is also designed to rest under prestress against the upper side of the second bearing bar. This achieves a particularly secure connection between the hanger and the C- profile, with rattling being avoided in particular. The prestressing can be achieved in particular by the second portion forming a main plane and the first holding portion being arranged at an angle of between 80° and 89° (preferably between 86° and 88°) to the main plane of the second portion.
If the second portion has beads, it can be provided that the region of the second portion lying outside of the beads forms the main plane.
A particularly advantageous embodiment of the invention provides that the first holding portion is formed by a first bent region of the second portion. The second holding portion is preferably formed by a second bent region of the second portion. This contributes to high stability and low production costs.
A preferred embodiment of the invention provides that the hanger has a width B' in the region of the first and the second holding portions, the width B' being between 100% and 110% of the width B. Preferably the width B' is between 101% and 108% of the width B.
According to the invention, it is particularly preferred that the first holding portion has a closed surface and/or a closed peripheral contour. In particular, it can be provided that the first holding portion has no recesses or holes in the interior of the holding portion or in the peripheral contour. If a second holding portion is provided, it can have the same feature. This achieves increased stability against bending. In this way it can be achieved that the first and the second holding portions rest only against the desired region of the C-profile (in this case the upper side of the first and the second bearing bars).
A further preferred embodiment of the invention provides that the first holding portion is connected to the second portion via a third bending line. It can furthermore be provided that the second holding portion is connected to the second portion via a fourth bending line. This contributes in particular to good stability and low production costs.
According to the invention, it can advantageously be provided that the first holding portion has a holding portion length in a direction perpendicular to the third bending line, which holding portion length is between 5% and 30% (preferably more than 10%, preferably less than 25%) of the width B of the second portion. It can furthermore be provided that the second holding portion has a holding portion length in a direction perpendicular to the fourth bending line, which holding portion length is between 5% and 30% (preferably more than 10%, preferably less than 25%) of the width B of the second portion.
A further preferred embodiment provides that the first holding portion has a holding portion width in a direction parallel to the third bending line, which holding portion width is between 10% and 25% of the width B of the second portion. It can furthermore be provided that the second holding portion has a holding portion width in a direction parallel to the fourth bending line, which holding portion width is between 10% and 25% of the width B of the second portion.
The stability of the hanger can be further improved in that the first bearing portion has a first bearing edge and the second bearing portion has a second bearing edge. The load transmitted by the C-profile can be absorbed particularly effectively with the bearing edge.
It can be advantageously provided that the first bearing edge is formed by the edge of a first recess, and the second bearing edge is formed by the edge of a second recess in the second portion. The recess can in particular be designed as a cutout or punched-out portion in the sheet metal material of the hanger.
Furthermore, it has proven to be advantageous if the edge of the first recess is formed obliquely, so that the first bearing edge is inclined towards the middle of the second portion. In addition, it can be provided that the edge of the second recess is formed obliquely, so that the second bearing edge is inclined towards the middle of the second portion. The first bearing edge preferably comprises an inclined straight portion which extends over at least 50% of the bearing edge.
The inclination of the bearing edge preferably runs from the top outside to the bottom inside, relative to the second portion. This bevel allows the bearing bar(s) to snap into the recess(es) of the second portion.
According to the invention, it is particularly preferred that the body is formed from sheet metal.
It can furthermore be provided that the sheet metal thickness is between 0.4 mm and 1 .2 mm. The sheet metal thickness is preferably between 0.6 mm and 0.8 mm. Furthermore, it is preferred that the body having the first and the second portions as well as the first and the second support portions and the first holding portion is produced by forming (preferably bending) from a single piece of sheet metal. If the body also has a second holding portion, this can also be produced by forming from the same piece of sheet metal. The piece of sheet metal is preferably processed by a separating method (particularly dividing, such as punching, for example) before forming.
A preferred embodiment provides that the first portion and/or the second portion have reinforcing beads. Reinforcing beads are preferably provided, which extend continuously from the second portion into the first support portion and/or the second support portion. The stability is further improved if the beads are designed in such a way that they protrude towards the inner side of the first or second support portion. In this way, a level contact of the first and the second support portions on the inner side of the profile flange is achieved, which ensures good force transmission.
According to the invention, it is further preferred that the first portion has connecting means for connection to the building.
The connecting means can be arranged on the first or the second main surface of the body. A particularly good stability is achieved when the connecting means are arranged on the second main surface.
According to an advantageous embodiment, the connecting means comprise a connecting portion with a plurality of holes arranged one below the other in a row. The distances between the holes are preferably the same. The holes can in particular form so-called vernier perforations or nonius perforations. The holes arranged in this way make it possible to arrange the hanger at different height positions relative to an upper part of the hanger and to fix it with push-through elements. For this purpose, the upper part of the hanger can also have a row of holes which are arranged to correspond to the holes in the hanger.
According to a further advantageous embodiment, the connecting means comprise a spring with two spring flaps, which spring is attached to the first portion. The spring flaps can each have a through opening for the introduction of a suspension wire. Furthermore, it can be provided according to the invention that no movable clamping element for generating a clamping force between the profile web and the second portion is arranged on the second portion.
The aforementioned width B of the second portion is preferably determined in the horizontal direction in the assembly position of the hanger. The width B1 mentioned above can also be determined in the assembly position of the hanger in the horizontal direction. The assembly position refers to the orientation of the hanger in the intended assembled state.
According to the invention, it can be provided that the first direction is opposite to the second direction.
The object on which the invention is based is also achieved with a dry construction arrangement. The dry construction arrangement comprises a hanger of the type described herein, and a C-profile, which has a profile web a first profile flange having a first bearing bar and a second profile flange having a second bearing bar.
A preferred embodiment provides that the width B of the second portion is between 95% and 105% (preferably between 99% and 101%) of the distance between the first and the second profile flanges before assembly.
According to the invention, it is particularly preferred if an intermediate space is formed between the hanger and the profile web, so that the hanger does not touch the profile web. Resting against the profile web is also not necessary, since good force transmission is already achieved with the bearing portions, the support portions, and the holding portions, whereby rattling can be avoided.
The object on which the invention is based is also achieved with a method for producing a suspended ceiling. The method provides that a C-profile, which has a profile web and a first profile flange having a first bearing bar and a second profile flange having a second bearing bar, is attached to a part of a building using a hanger described above.

Fig. 1A to 1E show a first embodiment of a hanger 1 according to the invention for dry construction. The hanger 1 comprises a body 2 having a first portion 3 for connection to a building and a second portion 4 for connection to a C-profile. As will be explained in more detail below in connection with Fig. 2, the C-profile to which the hanger 1 is connected has a profile web and a first profile flange having a first bearing bar and a second profile flange having a second bearing bar.
The second portion 4 has a first bearing portion 5 for resting against an underside of the first bearing bar and a second bearing portion 6 for resting against an underside of the second bearing bar.
Furthermore, the second portion 4 has a first holding portion 7 for resting against an upper side of the first bearing bar. In the embodiment shown, a second holding portion 8 is also provided for resting against an upper side of the second bearing bar.
The body 2 is made of sheet metal in the illustrated embodiment. In particular, the body 2 can be made of sheet steel. The sheet steel can in particular be galvanized. The body 2 has a first main surface 14 on a first side 13 and a second main surface 16 on a second side 15. The first and the second main surfaces 14, 16 are formed by the two opposite sides of the sheet.
The hanger 1 also has a first support portion 9 on the first bearing portion 5, which first support portion has a first side surface 11 for resting against an inner side of the first profile flange of the C-profile. A second support portion 10 having a second side surface 12 is arranged on the second bearing portion 6 for resting against an inner side of the second profile flange of the C-profile.
Fig. 1A to 1E also show that the first and the second support portions 9, 10 point from the second portion 4 in the first direction R1 . It can be seen in particular in Fig. 1A and 1B that the first and the second support portions 9, 10 each have a free end. The free end of the first and the second support portions points in the first direction R1 .
The first and the second support portions 9, 10 are each connected to the second portion 4 via a bent region. The first support portion 9 is connected to the second portion 4 via a first bending line 21. The second support portion 10 is connected to the second portion 4 via a second bending line 22.
The first support portion 9 has a support portion length SL in a direction perpendicular to the bending line 21 . The second support portion 19 also has a support portion length SL in a direction perpendicular to the second bending line 22.
In the embodiment shown, the support portion length SL is between 5% and 20% of the width B of the second portion 4 in the region of the first and the second support portions.
The first support portion 9 has a support portion height SH in a direction parallel to the first bending line 21 , and the second support portion 10 has a support portion height SH in a direction parallel to the bending line 22. In the illustrated embodiment, the support portion height SH is between 10% and 25% of the width B of the second portion 4.
It can be seen in particular in Fig. 1 A that the second portion 4 forms a main plane, and the first and the second support portions 9, 10 are each arranged at right angles to the main plane. In the installed position of the hanger 1 , the result is that the first and the second support portions 9, 10 (apart from any beads provided) are arranged in a vertical plane. Fig. 1A to 1E also show that the first holding portion 7 and the second holding portion 8 point away from the second portion 4 in the second direction R2. Thus, the first and the second holding portions 7, 8 point in an opposite direction compared to the first and the second support portions 9, 10. The first holding portion 7 has a free end pointing in the second direction R2. The second holding portion 8 also has a free end pointing in the second direction R2.
The first holding portion 7 is designed as a first bent flap. The second holding portion 8 is designed as a second bent flap. The first and the second flaps are flat, so that they only rest against the upper side of the first and the second bearing portions (cf. also Fig. 2).
The first and the second holding portions 7, 8 are designed to be arranged completely above the first and the second bearing portions of the C-profile in the assembled state (cf. Fig. 2).
The first holding portion 7 and the second holding portion 8 are designed to be prestressed against the upper side of the first or the second bearing bar of the C-profile. This can be achieved in that the second portion 4 forms a main plane, and the first and the second holding portions 7, 8 are each arranged at an angle W of between 80° and 89° to the main plane.
Fig. 1C shows that the first bearing portion 5 has a first bearing edge and the second bearing portion 6 has a second bearing edge. The first bearing edge is formed by the edge of a first recess 24. The second bearing edge is formed by the edge of a second recess 25. The first and the second recesses 24, 25 can be produced in particular by punching or another separation method.
As illustrated, the edge of the first recess 24 is formed obliquely, so that the first bearing edge is inclined towards the middle of the second portion. The edge of the second recess 25 is also formed obliquely, so that the second bearing edge is inclined towards the middle of the second portion.
Fig. 1A to 1E also show that the body 2 has a plurality of beads 26. These are formed in the sheet metal body of the body 2 and stiffen the body 2. In the embodiment shown, the beads 26 extend from the second portion 4 into the first and the second support portions 9, 10. Beads 26 are also formed in the first portion 3 of the body and extend into the second portion 4. It can also be seen in Fig. 1A to 1E that the first holding portion 7 is formed by a first bent region of the second portion 4. The second holding portion 8 is formed by a second bent region of the second portion 4.
The first and the second holding portions 7, 8 are designed in such a way that the hanger 1 has a width B' in the region of the first and the second holding portions 7, 8, the width B' being between 100% and 110% of the width B of the second portion 4 in the region of the first and the second support portions 5, 6.
In the example shown, the first holding portion 7 and the second holding portion 8 each have a closed surface and a closed peripheral contour. Undesirable deformation of the first or second holding portion 7, 8 is thus avoided.
The first holding portion 7 is connected to the second portion 4 via a third bending line 27. The second holding portion 8 is connected to the second portion 4 via a fourth bending line 28.
In a direction perpendicular to the third bending line 27, the first holding portion 7 has a holding portion length HL which is between 5% and 30% of the width B of the second portion 4. In this example, in a direction perpendicular to the fourth bending line 28, the second holding portion 8 has a holding portion length HL which is also between 5% and 35% of the width B of the second portion 4.
In a direction parallel to the bending line, the first holding portion 7 has a holding portion width HB which is between 5% and 25% of the width B of the second portion 4.
In a direction parallel to the fourth bending line 28, the second holding portion 8 has a holding portion width HB which is also between 5% and 25% of the width B of the second portion 4.
The body 1 of the illustrated embodiment is made of sheet metal. The sheet metal, which is initially flat, is brought into the shape shown in the figures by forming after it has been cut out. In particular, the first and the second support portions 9, 10 and the first and the second holding portions 7, 8 can be formed by bending. The beads 26 can also be introduced by forming. The hanger 1 has connecting means 29 for fastening the body 2 to a building component, such as a raw ceiling. In the embodiments illustrated in Fig. 1A to 1E, the connecting means 29 comprise a spring 30 having two spring flaps 31. The spring 30 is connected to the body 2 via fastening means 50 (shown as rivets).
A through opening 32 for the introduction of a suspension wire is provided in each spring flap 31 . Fig. 1E shows the hanger 1 with such a suspension wire 33. The suspension wire 33 has an eyelet at its upper end, with which it can be attached to a building component, in particular a raw ceiling.
Fig. 2 shows the hanger 1 from Fig. 1A to 1E, inserted into a C-profile 40. The C-profile 40 has a profile web 41 on which a first and a second profile flange 42, 43 are arranged. The first profile flange 42 has a first bearing bar 44. The second profile flange 43 has a second bearing bar 45. The first and the second bearing bars 44, 45 each extend inwardly from the first and the second profile flanges 42, 43. The C-profile 40 consists of sheet metal. The first and the second profile flanges 42, 43 and the first and second bearing bar 44, 45 are produced by bending a piece of sheet metal. In the embodiment shown, the first and the second profile flanges 42, 43 have beads 46. A centrally arranged bead 47 is also formed in the profile web 41. The beads 46; 47 each extend in the longitudinal direction of the C-profile 40.
The C-profile 40 rests with the first and the second bearing bars 44, 45 against the first and the second bearing portions 5, 6 of the hanger 4. In this way, a weight force acting downwards can be reliably transmitted from the C-profile 40 to the hanger.
It can also be seen in Fig. 2 that the first and the second holding portions 7, 8 rest only against the upper side of the first and the second bearing bars 38, 39. In particular, the first and the second holding portions 7, 8 do not rest against the outer side of the first and the second profile flanges 42, 43.
Fig. 3A and 3B show an embodiment of a hanger 11 which - as far as the second portion 4 is concerned - corresponds to the embodiment from Fig. 1A to 1E. In particular, the hanger 1 ' from Fig. 3A and 3B again has a first and second support portion 9 and 10 and a first and second holding portion 7, 8. Reference is made to the description of Fig. 1, which applies accordingly to the embodiment of Fig. 3A and 3B insofar as there are similarities. The hanger 1' from Fig. 3A and 3B differs in the design of the connecting means. As shown, the first portion 3 has holes which are in the form of vernier or nonius perforations 50. This comprises a plurality of holes arranged one below the other in a row. In the illustrated embodiment, these are arranged in a U-shaped region of the first portion 3. In this way, the hanger 1' can be positioned at different heights relative to an upper part 51 of the hanger. The upper part 51 of the hanger and the hanger 1' can be fixed to one another with push- through elements 52. The upper part 51 of the hanger also has a series of holes which are arranged to correspond to the holes in the vernier perforations 50. This is shown in Fig. 3B.
Fig. 4 shows the assembly of the hanger 1 from Fig. 1E in a C-profile 40. As shown on the left in Fig. 4, the hanger 1 can first be inserted into the space of the C-profile 40 formed between the profile flanges 42, 43. The hanger 1 is then rotated (cf. Fig. 4, middle) until it reaches its final position (cf. Fig. 4, right). In this position, the first bearing portion 5 is arranged under the first bearing bar 44 and the second bearing portion 6 is arranged under the second bearing bar 45. The first holding portion 7 is located above the first bearing bar 44, while the second holding portion 8 is located above the second bearing bar 45. Typically, a C-profile of the dry construction arrangement is attached using two or more hangers 1 spaced along the length of the C-profile 40.
Fig. 5 schematically shows a dry construction arrangement. Only a single hanger 1 is shown in this case for better visual representation. The hanger 1 is connected to the C-profile 40 via its second portion 4 in the manner described above. The first portion 3 is connected to a building component 48, which is shown schematically in this case as a portion of a shell ceiling. This is done using the suspension wire 33. Fig. 5 also shows a ceiling cladding 49. This can in particular comprise a dry construction board which is attached to the C-profile 40 and in particular to the profile web 41. The dry construction board can be connected to the profile web 41 with fastening means which can be designed in particular as screws. The dry construction board can in particular be a plasterboard. Of course, dry construction cladding made of other materials that can be assembled using this system are also included in the scope of protection.
