Description

[0001] Holding brace, dry construction structure with holding brace and method for assembling a dry construction structure

[0002] The invention relates to a holding brace for a dry construction structure, a dry construction structure with a holding brace and a method for creating a dry construction structure.

[0003] Holding braces are regularly used in metal structures to increase their load-bearing capacity or to prevent impermissible deformations.

[0004] From Engineer’s Notebook, February 2017, it is already known to connect parallel dry construction profiles with holding braces. The disadvantage of the previously known holding braces is that they require time-consuming and error-prone assembly when creating dry construction structures.

[0005] It is therefore an object of the invention to further develop a holding brace and a dry construction structure as well as a method for creating a dry construction structure, so that these enable quick and safe assembly of stable constructions in the field of dry construction.

[0006] This object is achieved by a holding brace having the features of claim 1 . Accordingly, a holding brace for a dry construction structure is provided, comprising a holding strip and a first wing arranged at a first longitudinal position of the holding strip and a second wing arranged at a second longitudinal position of the holding strip, wherein the first wing and the second wing each have a connection section for connecting to the holding strip, wherein the connection section is configured, such that the first wing and the second wing can assume an assembly position in which the first wing and the second wing are arranged transversely to the holding strip. This design offers various advantages. Such a holding brace allows a reliable, precise and safe assembly of dry construction structures. In particular, the holding brace can be used to connect dry construction profiles, which can have different material thicknesses, in a particularly simple way. Preferred applications are ceilings and walls. The holding brace allows a quick and precise assembly. The holding brace with the first and second wings and the holding strip can be used to connect dry construction profiles to each other in a stable manner. Occurring stresses that would lead to impermissible deformations can be counteracted. In particular, impermissible deformations and torsional flexural buckling of dry construction profiles are avoided. This reduces the need for other measures to prevent impermissible deformations. Dry construction structures can be effectively reinforced with the holding brace. During assembly, it is advantageous that the first and second wings arranged at the first and second longitudinal positions allow the dry construction profiles to be easily mounted at a predetermined distance without having to be measured in each case. This can significantly improve the assembly speed and repeat accuracy during assembly of the dry construction profiles. In particular, it is possible to prepare the holding braces in such a way that the distance between the first and second wing is dimensioned in such a way that dry construction profiles assembled using the holding brace are arranged at a center distance common in dry construction. This is important for dry construction structures, for example, where the dry construction profiles are to be assembled in such a way that prefabricated boards of a planking system can be attached without changing the dimensions of the boards. By arranging the first and second wings in relation to the holding strip in the claimed manner, effective force transmission can be achieved. This reduces the amount of material used and saves costs. Another advantage is that the space between the dry construction profiles can be kept largely free when using the holding brace and can therefore be used for installations and / or insulation. For walls in particular, it is advantageous that the holding brace can be used for backing the joints of the planking. The claimed holding brace can also be manufactured easily, with high process reliability and at low cost.

[0007] A width of the holding strip can be preferably between 3 cm and 10 cm (particularly preferably between 4 cm and 6 cm). A wing width can preferably be between 4 cm and 5 cm. The length of the holding strip can be adapted to the center distance between the dry construction profiles.

[0008] Center distances between the dry construction profiles, as bridged by the holding brace according to the invention, can preferably be in the range between 30 cm and several meters. Common center distances are — to name just a few examples — 400 mm, 500 mm, 625 mm, 750 mm, 1000 mm, 1250 mm, 1500 mm.

[0009] In principle, the shape of the holding strip is not limited. In a preferred manner, however, the holding strip is essentially formed in the shape of a flat, elongated rectangle, i.e., has two essentially parallel longitudinal edges. The end regions of the holding strip can be formed by transverse edges running at right angles to the longitudinal edges, resulting in a “genuine” rectangle. In the end regions, however, the holding strip can also be formed in such a way that the corners are rounded, the end pieces have semi-circular transverse edges, run at an angle to the longitudinal edges or deviate from the strict rectangular shape in some other way. These variants of the holding strip are comprised below by the term “essentially rectangular”, in particular if the longitudinal edges are parallel in the region between the wings.

[0010] In an advantageous way, the wings protrude from the essentially rectangular shape of the holding strip.

[0011] Further advantageous embodiments are described below which, among other things, further enhance the aforementioned advantages.

[0012] In an advantageous way, the first and second wings can be formed as separate wings, having a free intermediate space formed between them. This not only contributes to material savings, but also makes assembly easier. In particular, the first and second wings can be moved more easily from the transport position to the assembly position if the intermediate space is provided between the first and second wings.

[0013] There are preferably regions without material (such as gaps) in front of or behind the outermost wings. This serves to save material. However, in the aforementioned regions — particularly in the region between a first and the nearest second wing — it is also possible to provide surface sections that can assume angled positions in relation to the holding strip by means of their own connection sections to the holding strip. Such intermediate surface sections can be particularly advantageous if the stability of the holding strip is to be increased.

[0014] An advantageous embodiment of the invention provides that the holding strip is formed flat and is arranged in a first plane and that the first wing and / or the second wing have at least one flat surface section, wherein, in the assembly position, the flat surface section of the respective first and / or second wing is arranged in a second plane which is arranged at an angle to the first plane. Preferably, the second plane is arranged at right angles to the first plane. Preferably, the flat surface sections of the first wing and / or the second wing are not arranged parallel to the first plane of the holding strip in the assembly position.

[0015] According to the invention, it is particularly preferred that the first wing and the second wing can assume a transport position in which the first wing and / or the second wing (or the flat surface sections of the respective first and second wings) are arranged parallel (preferably coplanar) to the first plane of the holding strip. It is possible to produce the holding brace in the transport position. In this position, the holding brace is still flat, which makes transportation and storage considerably easier. Prior to assembly of the holding brace, the first and second wings are brought into the assembly position.

[0016] According to the invention, it can be provided that the connection section is plastically deformable. In this way, the first or second wing can be moved from the transport position to the assembly position. This can involve bending the connection section. Preferably, the connection section has a defined bending line. Preferably, the connection section can be bent manually. This means that the first and second wings can also be easily brought into the assembly position on the construction site. Preferably, the bendable connection section is configured to be pliable. This facilitates the defined forming of the first and second wing.

[0017] Preferably, the first wing and / or the second wing have a free end, wherein the connection section is arranged on a side of the first wing or second wing facing away from the free end.

[0018] Preferably, the first wing and / or the second wing have a rectangular basic shape.

[0019] A preferred embodiment provides that two first wings are provided which are arranged on opposite sides of the holding strip, and / or that two second wings are provided which are arranged on opposite sides of the holding strip. Preferably, the first wings and the second wings are each arranged in pairs axially symmetrically to a longitudinal central axis of the holding strip.

[0020] A further improvement can be achieved by the holding strip having several predefined second longitudinal positions for the second wing, each second longitudinal position having a different distance from the first longitudinal position. In this way, the holding brace can be used for different specified distances without the need for measurements or adjustments during assembly.

[0021] Preferably, the holding strip is manufactured in one piece with the first wing, e.g., cut out or punched out of one piece of sheet metal. This simplifies production. Alternatively, the holding strip with the first wing can also be assembled from several parts, for example welded together. For example, a metal sheet forming the first wing can be welded or otherwise permanently attached to a long metal sheet forming the holding strip. In an embodiment without the holding piece described below, the holding strip can be manufactured in one piece from a metal sheet with the first wing and the second wing.

[0022] According to the invention, it is particularly advantageous if a separate holding piece is provided comprising the second wing, wherein the separate holding piece is formed to be connected to the holding strip at the second longitudinal position. In this way, the holding brace can be made up of two elements. This makes assembly even more flexible. In the embodiment with several predefined longitudinal positions, the holding piece with the second wing can be attached at the desired longitudinal position. A first fastening means can be provided in order to fasten the holding piece with the second wing at the second longitudinal position on the holding strip. Preferably, the first fastening means comprises a bolt with a nut and / or a rivet.

[0023] The holding piece can preferably be made in one piece, e.g. from sheet metal, or it can be permanently assembled from several parts.

[0024] A particularly advantageous embodiment provides that the separate holding piece is crossshaped and has at least three holding piece arms. Two holding piece arms can be formed by the second wings. The third holding piece arm can be a holding piece section for connecting to the holding strip. The cross-shaped design not only enables good transmission of forces, but is also easy and inexpensive to manufacture.

[0025] In particular, the holding brace can be produced in the transport position, for example by punching out a piece of sheet metal, before the two holding brace arms that form the second wings are bent over.

[0026] A further improvement provides that the holding piece has an elongated guide section that extends parallel to the holding strip and rests against it. Preferably, the guide section can form a fourth of the holding piece arms of the cross-shaped holding piece. The elongated guide section can not only enable better force transmission between the holding piece and the holding strip. It also extends the options for attaching the holding piece to the holding strip in an adjustable manner.

[0027] In an advantageous manner, it can be provided that the holding strip and the holding piece each have at least one first through-opening for receiving the first fastening means. An advantageous embodiment provides that the first through-opening is formed as a circular opening. This enables precise positioning of the holding piece at the second longitudinal position. This makes it particularly easy to use the holding brace to position two dry construction profiles at the distance specified by the first and second longitudinal positions. According to the invention, the first through-opening of the holding strip and / or the holding piece can also be formed as a slotted hole. This allows the distance between the first and second longitudinal position to be continuously adjusted. This means that the holding brace is particularly suitable to be subsequently mounted to previously mounted dry construction profiles.

[0028] Furthermore, it can be provided that the holding piece has at least one second through- opening for receiving a second fastening means in order to connect the holding piece to the holding strip. Preferably, the at least one second through-opening is formed as a slotted hole. An embodiment as a slotted hole has the advantage that the guide section can be arranged on the holding strip in a continuously adjustable manner. Preferably, the at least one second through-opening is arranged in the guide section. In this way, the holding brace can be continuously adjusted to the required distances between dry construction profiles. This means that the holding brace is also suitable to be subsequently mounted to previously mounted dry construction profiles.

[0029] According to the invention, it can be provided that the holding strip has several second longitudinal positions which are spaced at different distances from the first longitudinal position. Preferably, the second longitudinal positions are arranged in a straight line. Preferably, each second longitudinal position comprises one of the first through-openings.

[0030] A preferred embodiment of the invention provides that the holding strip forms a first connection section for connecting to a first dry construction profile and a second connection section for connecting to a second dry construction profile. Preferably, the first connection section is allocated to the first longitudinal position and the second connection section to the second longitudinal position. Preferably, the first and second connection sections are arranged in the first plane.

[0031] Preferably, the first connection section is arranged on the side of the first wing facing away from the second longitudinal position and the second connection section is arranged on the side of the second wing facing away from the first longitudinal position.

[0032] A particularly preferred embodiment provides for the holding strip to be cross-shaped in the region of the first longitudinal position, with a first arm forming the first connection section, a second and a third arm, each formed by a first wing, and a fourth arm connecting the first longitudinal position to the second longitudinal position. Here, the first wing can be arranged at a distance from a first end of the holding strip, wherein the distance is determined by the length of the first arm.

[0033] According to the invention, it is preferred that a third fastening means is provided to connect the holding strip to a dry construction profile. Preferably, the third fastening means is arranged in the first connection section. For this purpose, the first connection section can have a push- through opening.

[0034] According to the invention, it is preferred that a fourth fastening means is provided in order to connect the holding strip to a second dry construction profile. Preferably, the fourth connection means is arranged in a section of the holding strip that is at a greater distance from the first longitudinal position than the second longitudinal position. Preferably, the fourth fastening means is arranged in the second connection section. For this purpose, the second connection section can have a push-through opening.

[0035] A further improvement provides that a third wing is provided which is arranged at a third longitudinal position of the holding strip. Preferably, two third wings are provided which are arranged on opposite sides of the holding strip. One advantage of providing a third wing is that the holding brace can be used for different distances between dry construction profiles without further ado.

[0036] It is advantageous if a free space is formed between the second and third wing. Preferably, the free space forms a receiving section for a dry construction profile. This contributes to a particularly stable connection between the dry construction profile and the holding brace. For this, the free space can preferably be between 27 mm and 105 mm.

[0037] Furthermore, it can be provided that at least one further wing is provided, which is arranged on at least one further longitudinal position of the holding strip. Preferably, at least two further wings are provided which are arranged on opposite sides of the holding strip. It is preferable if a further free space is formed between the third wing and the further wing.

[0038] In an advantageous manner, it can be provided that the third wing and / or the further wing can assume an assembly position in which the respective wing is arranged transversely to the holding strip. According to the invention, it is preferred that the holding strips and the first and second wings are made of sheet steel. Preferably, the holding strip is formed as a single punched part. The holding piece is preferably made of sheet steel.

[0039] Preferably, the sheet steel has a material thickness of between 0.5 mm and 5 mm. A material thickness of between 1 and 3 mm, for example 1 .5 mm or 2 mm, is particularly preferred.

[0040] The invention also relates to a dry construction structure, comprising at least a first and a second dry construction profile and at least one holding brace of the type described, wherein the holding brace connects the first and the second dry construction profile. In this way, the holding brace makes it possible to stabilize the dry construction structure. Impermissible bending and twisting of the dry construction profiles is counteracted.

[0041] Preferably, the holding brace rests against the first dry construction profile with the first wing and against the second dry construction profile with the second wing. In this way, forces can be transmitted in a particularly effective manner. The holding brace can also be used to position the dry construction profiles in a manner true to size.

[0042] A particularly stable construction is achieved when the first and second wings are arranged between the first and second dry construction profiles.

[0043] Preferably, the first dry construction profile and the second dry construction profile each have a web and two flanges. The first and second dry construction profiles each preferably comprise a C-profile or a U-profile. Particularly high stability is achieved when the first and second dry construction profiles comprise two C-profiles connected back-to-back.

[0044] Preferably, the first dry construction profile and / or the second dry construction profile are made of sheet steel. Preferably, the sheet steel has a thickness of between 0.5 mm and 3 mm. Material thicknesses between 1 and 3 mm, for example 1.5 mm or 2 mm, are particularly preferred.

[0045] A further improvement provides that the dry construction structure has planking. The planking can be arranged on the dry construction profiles. Preferably, the planking comprises boards, such as in particular gypsum boards, gypsum fiberboards, fiber cement boards, wood boards and / or wood fiberboards. Gypsum boards are particularly preferred according to the invention. Preferably, the planking is arranged on one of the flanges of the dry construction profiles. In particular, the boards can be wall panels and / or ceiling panels.

[0046] Preferably, the dry construction structure forms a suspended ceiling or a wall. The planking can form the wall surface or ceiling surface.

[0047] Preferably, the first and second dry construction profiles are arranged parallel to each other. In case of a ceiling, the dry construction profiles can be arranged horizontally. In case of a wall, the dry construction profiles can be vertically arranged studs.

[0048] An advantageous embodiment provides for the holding brace to be attached to the flange of the first dry construction profile with the first connection section and to the flange of the second dry construction profile with the second connection section. This enables the quick creation of stable dry construction structures. In addition, the space between the dry construction profiles remains free to accommodate installations.

[0049] The holding strip can have two main surfaces and preferably rests flat against the flange with one of the main surfaces.

[0050] Preferably, the dry construction structure forms a ceiling or a wall.

[0051] A further preferred embodiment provides for the holding brace to be connected to the web of the first and / or second dry construction profile. This embodiment also enables the creation of stable dry construction structures. As the holding brace is not connected to the flanges, these remain free and can easily receive the planking.

[0052] According to a further development of the invention, it may be provided that the first and second dry construction profiles each have a cutout in the web through which the holding brace extends. This embodiment is particularly suitable when the first and second dry construction profiles are arranged vertically in a wall.

[0053] The dry construction structure can comprise at least one fastening angle to connect the holding brace to the web of the first or second dry construction profile.

[0054] The dry construction structure according to the invention can be non-load-bearing or loadbearing. As a load-bearing structure, it can assume a structural function in the building. This means that the holding brace can be used both in dry construction for interior fittings without a structural load-bearing function and in lightweight steel construction with a load-bearing function.

[0055] The invention also relates to a method for assembling a dry construction structure in which a first and a second dry construction profile are connected by a holding brace of the type described.

[0056] In addition, the invention also relates to the use of a holding brace of the type described for connecting two dry construction profiles of a dry construction structure.

[0057] Preferably, it is possible to use the holding brace to position the second dry construction profile at a distance from the first dry construction profile specified by the first and second longitudinal positions of the holding strip.

[0058] The holding brace with holding piece can be used to adjust the length of the holding brace to the distance between the first and second dry construction profile. The first and second dry construction profiles may have already been mounted beforehand.

[0074] Figs. 1a and 1 b show a holding brace 1 for a dry construction structure. The holding brace 1 comprises a holding strip 2 and first wings 3, which are arranged at a first longitudinal position

[0075] 4 of the holding strip 2. The holding brace 1 also has second wings 5, which are arranged at a second longitudinal position 6 of the holding strip 2. In the exemplary embodiment shown, two first wings 3 and two second wings 5 are provided. The first wings 3 and the second wings

[0076] 5 are each arranged in pairs axially symmetrical to a longitudinal central axis of the holding strip 2.

[0077] The first wing 3 and the second wing 5 each have a rectangular basic shape. The first and second wings 3, 5 are each connected to the holding strip 2 via a connection section 7. The connection section 7 is configured such that the first wing and the second wing 3, 5 can assume the assembly position depicted in Fig. 1 b, in which the first wing 3 and the second wing 5 are arranged transversely to the holding strip 2.

[0078] The holding strip 2 is formed flat and arranged in a first plane. As depicted in Fig. 1 b, the first wing 3 and the second wing 5 each have at least one flat surface section which, in the assembly position depicted in Fig. 1 b, is arranged in a second plane which runs at an angle to the first plane. In the depicted exemplary embodiment, the second plane is arranged perpendicular to the first plane.

[0079] Fig. 1a shows the holding brace 1 before the first and second wings 3, 5 have been brought into the assembly position. This position is also referred to as transport position. The holding brace 1 can initially be manufactured in this form. In the depicted transport position, the first wing 3 and the second wing 5 are arranged parallel and coplanar to the first plane of the holding strip. Before mounting the holding brace 1 , the first and second wings 3, 5 are moved from the transport position depicted in Fig. 1a to the assembly position depicted in Fig. 1 b. For this purpose, the first and second wings 3, 5 are bent about the plastically deformable connection section 7. The connection section 7 can be formed as a bending line. In particular, the connection section 7 can be formed, so that the first and second wings 3, 5 can be brought from the transport position into the assembly position by bending. If no particularly thick sheets are required for reasons of stability, the first and second wings 3, 5 can be bent by hand or with a hand tool on site.

[0080] If a material weakening (not depicted) is provided in the region of the connection section 7, e.g., by a cutout, perforation, deformation or groove, the bending of the wings along the connection section 7 can be made easier. This applies in particular to thicker materials. The material can be weakened, e.g., by punching out.

[0081] The first and second wings 3, 5 each have a free end 8. The connection section 7 is arranged on the side of the first or second wing 3, 5 facing away from the free end 8.

[0082] In the exemplary embodiment depicted in Figs. 1a and 1 b, the holding brace 1 has third wings 9 at a third longitudinal position 23. In addition, further wings 10 and 10’ are provided at further longitudinal positions 24, 24’. The third wings 9 and the further wings 10 are again arranged in pairs on both sides of the holding strip 2. The third wings 9 and the further wings 10, 10’ are formed like the second wings 5. This makes it possible to install dry construction profiles at various predetermined distances using the holding brace 1 . For a closer distance between two dry construction profiles, the latter are mounted using the first and second wings 3, 5. If a greater distance is required, the dry construction profiles can be mounted using the first wing 3 and the third wing 9 or a further wing 10, 10’. This results in predefined distances. This eliminates the need for time-consuming and error-prone measuring of the distance during assembly of dry construction profiles.

[0083] Figs. 1a and 1 b also show that a free space 11 is formed between the second wing 5 and the third wing 9. As will be explained below in connection with Fig. 6, this free space 11 forms a receiving section for a dry construction profile. Corresponding free spaces 1 1 are also formed between the third wing 9 and the further wing 10 and the further wing 10’.

[0084] The holding strip 2 with the first and second wings 3, 5 and the third wing 9 and the further wings 10, 10’ is formed as a one-piece sheet metal part made of sheet steel. The holding strip 2 has a first connection section 12 for connecting to a first dry construction profile and a second connection section 13 for connecting to a second dry construction profile. The first connection section 12 is arranged on the side of the first wing 3 facing away from the second longitudinal position 6. The second connection section 13 is arranged on the side of the second wing 5 facing away from the first longitudinal position 4.

[0085] The holding strip 2 is cross-shaped in the region of the first longitudinal position 4, with a first arm, forming the first connection section 12, and a second arm and a third arm formed by the two first wings 3. A fourth arm connects the first longitudinal position 4 with the second longitudinal position 6. The first wing 3 is arranged at a distance from a first end of the holding strip 2, wherein the distance is determined by the length of the first arm.

[0086] The holding strip 2 has third and fourth through-openings 14, 14’ for receiving a third and a fourth fastening means (see Fig. 5). The third through-opening 14 is arranged in the first connection section 12 and the fourth through-opening 14’ is arranged in the second connection section 13. One of the fourth through-openings 14’ is also formed in each of the intermediate sections 15. In this way, the holding brace 1 can be used for the assembly of dry construction profiles at different distances.

[0087] A width HB of the holding strip 2 can preferably be between 3 cm and 10 cm (particularly preferably between 4 cm and 6 cm). A wing width FB of the first and second wings 3, 5 can preferably be between 4 cm and 5 cm. A length HL of the holding strip 2 is adapted to the center distance between the dry construction profiles.

[0088] As depicted, the first and second wings 3, 5 are formed as separate wings, between which an intermediate space 50 is formed. This makes it easier to move the first and second wings 3, 5 from the transport position to the assembly position.

[0089] Figs. 2a and 2b show a second embodiment of a holding brace 1 ’. The holding brace 1 ’ again has an elongated holding strip 2’ on which two first wings 3 are arranged as in the embodiment depicted in Figs. 1a and 1 b. Fig. 2a shows the holding brace T in the transport position, while the assembly position is depicted in Fig. 1 b.

[0090] The holding strip 2’ of the holding brace T has several second longitudinal positions 6 for the second wing 5, each second longitudinal position 6 being at a different distance from the first longitudinal position 4. In the embodiment from Figs. 2a and 2b, a separate holding piece 16 is provided with the second wing 5. In the depicted exemplary embodiment, the holding piece 16 has two second wings 5. The holding piece 16 can be connected to the holding strip 2’, as depicted in Fig. 2b.

[0091] The separate holding piece 16 is cross-shaped and has at least three holding piece arms. Here, two holding piece arms can be formed by the second wings 5 while the third holding piece arm is formed by a holding piece section 22 for connecting to the holding strip 2.

[0092] The holding piece 16 has an elongated guide section 21 that extends parallel to the holding strip 2 and rests against it. The guide section 21 can form a fourth of the holding piece arms of the cross-shaped holding piece 16.

[0093] Furthermore, a first fastening means 17 can be provided in order to connect the holding piece 16 to the second wing in the second longitudinal position 6 on the holding strip 2’. The holding strip 2’ and the holding piece 16 each have at least one first through-opening 18, 18’ for receiving the first fastening means 17. In the depicted exemplary embodiment, the first through-opening 18 in the holding piece 16 is circular. The first through-opening 18’ in the holding strip 2’ is formed as a slotted hole in the depicted exemplary embodiment.

[0094] The holding piece 16 also has two second through-openings 19. Second fastening means 20 can be arranged here to connect the holding piece 16 to the holding strip 2. In the depicted exemplary embodiment, the two second through-openings 19 are arranged in the guide section 21 and are formed as slotted holes.

[0095] Figs. 3a and 3b show a third embodiment of a holding brace 1 ” with a holding strip 2” and a holding piece 16’.

[0096] The third embodiment largely corresponds to the second embodiment. Reference is made to the relevant description which applies accordingly to the third embodiment.

[0097] The third embodiment differs from the second embodiment in that the first through-opening 18 in the holding piece 16’ is formed as a slotted hole. This increases the possibilities for continuous adjustment. Figs. 4a and 4b show a fourth embodiment of the holding brace 1 ”’ with a holding strip 2”’ and a holding piece 16”. The holding brace 1 ”’ is formed similarly to the holding brace 1 ’ according to the second embodiment. Reference is made to the relevant description which applies accordingly to the fourth embodiment.

[0098] The fourth embodiment differs from the second embodiment in that the first through-openings 18’ in the holding strip 2 are formed as circular openings. The first through-opening 18 in the holding piece 16” is also circular. Thus, this embodiment enables a precise positioning of the holding piece 16” on the holding strip 2”’. This means that the second wings 5 can be arranged at an exactly specified distance from the first wings 3 without having to carry out measurements.

[0099] The holding piece 16” depicted in Figs. 4a and 4b is shorter than the holding pieces 16 and 16’ and has only three holding piece arms and no guide section.

[0100] The holding pieces 16, 16’ and 16” from Figs. 2a, 3a and 4a can be used with each of the holding strips 2’, 2”, 2’” from Figs. 2a, 3a and 4a. If the holding piece 16 from Fig. 2b is combined with the holding strip 2’” from Fig. 4a, a precise positioning of the holding piece 16 can also be achieved with the first through-opening 18. At the same time, however, there is the option of assembly with variable spacing if the second through-openings 19 are used to receive a second fastening means 20.

[0101] Fig. 5 shows a dry construction structure 30, comprising a first and a second dry construction profile 31 , 32 which are arranged parallel to each other. In the depicted example, the first dry construction profile 31 and the second dry construction profile 32 each comprise two C-profiles 33 which are connected back-to-back. The C-profiles 33 each comprise a web 35 and two flanges 36. Clinches 34 are provided to connect the two C-profiles 33, which connect the webs 35.

[0102] The dry construction profiles 31 , 32 are connected by a holding brace 1 of the type described in connection with Figs. 1 a and 1 b. In contrast to the depiction in Fig. 1 b, only the first wings 3 and the second wings 5 have been brought into the assembly position in the holding brace 1 depicted in Fig. 5 while the third wings 9 and the further wings 10, 10’ have remained in the transport position. As depicted, the first and second wings 3, 5 are arranged between the dry construction profiles 31 , 32 and each wing 3, 5 rests against one of the flanges 36. The first connection section 12 rests on the flange 36 of the first dry construction profile 31. The second connection section 13 of the holding brace 1 rests on the flange 36 of the second dry construction profile 32.

[0103] Fig. 5 also shows a further embodiment of a holding brace 1 ””. The holding brace 1 ”” is formed similarly to the holding brace 1 in Fig. 1 b. However, it is shorter and has no third wing 9 and no further wings 10, 10’.

[0104] The holding braces 1 and 1 ”” are connected to the first dry construction profile 31 via a third fastening means 37 and to the second dry construction profile 32 via a fourth fastening means 38. The third and fourth fastening means 37, 38 are each inserted into the flange 36 of the first and second dry construction profile 31 , 32, respectively.

[0105] Fig. 6 shows a further embodiment of a dry construction structure 30’. This again has a first and a second dry construction profile 31 , 32 which are arranged parallel to each other. Fig. 6 also shows the holding brace 1 from Fig. 1 b.

[0106] In the depicted example, the first and second dry construction profiles 31 , 32 are formed as C-profiles and each comprise a web 35 and two flanges 36. The second dry construction profile 32 is received in the free space 1 1 between the second wing 5 and the third wing 9 and is thus fixed securely in the specified position.

[0107] The holding brace 1 is connected to the first dry construction profile 31 via a third fastening means 37 and to the second dry construction profile 32 via a fourth fastening means 38. The third and fourth fastening means 37, 38 are each inserted into the flange 36 of the first and second dry construction profile 31 , 32, respectively.

[0108] The exemplary embodiment depicted in Fig. 6 serves to explain the use of the holding brace 1 in a dry construction structure. In actual constructions, several holding braces 1 are generally used to connect the first and second dry construction profiles 31 , 32.

[0109] Fig. 7 shows a further embodiment of a dry construction structure 30”. It comprises first and second dry construction profiles 31 , 32 which are formed as in the embodiment depicted in Fig. 5. Fig. 7 shows the use of the holding brace 1 ’ from Fig. 2b and the holding brace 1 ’” from Fig. 4b. The first wings 3 and the second wings 5 are again arranged between the first and second dry construction profiles 31 , 32 and can be used to position the first and second dry construction profiles.

[0110] Fig. 8 shows a further embodiment of a dry construction structure 30”’. This again comprises first and second dry construction profiles 31 , 32 which are formed as in the embodiment depicted in Fig. 7. Fig. 8 shows the use of the holding brace 1 ” from Fig. 3b and the holding brace 1 from Fig. 4b. The first wings 3 and the second wings 5 are again arranged between the first and second dry construction profiles 31 , 32 and can be used to position the first and second dry construction profiles 31 , 32.

[0111] Fig. 9a shows a perspective view from above of a further embodiment of a dry construction structure 30””. The dry construction structure 30”” has several first and second dry construction profiles 31 , 32 arranged in parallel at a distance from one another. The dry construction profiles 31 , 32 are each connected to one another by the holding braces 1 ”” also depicted in Fig. 5. The depiction serves to explain the basic structure. In actual applications, the distances between the dry construction profiles 31 and 32 as well as between the holding braces 1 ”” may differ and be formed according to the respective structural requirements.

[0112] Fig. 9b shows the dry construction structure depicted in Fig. 9a with additional planking 39 in a perspective view from below. For reasons of clarity, the planking 39 is only partially depicted in Fig. 9b.

[0113] The planking 39 may comprise boards, such as in particular gypsum boards, gypsum fiber boards, fiber cement boards, wood boards and wood fiber boards. As depicted, the planking 39 can be arranged on the flanges 36 of the first and second dry construction profiles 31 , 32. In Fig. 9b, the joints between the boards of the planking 39 are covered with joint cover strips 40. Joint cover strips 40 are optional, and usually bonded to the boards of the planking 39 before applying a finishing coat and are used, among other things, to absorb tensile stresses, such as thermal stresses, which could otherwise lead to cracks in the region of the joint.

[0114] The embodiment depicted in Figs. 9a and 9b is particularly suitable for the creation of a ceiling. In this case, the first and second dry construction profiles 31 , 32 can be aligned horizontally, wherein the planking 39 is arranged on the downward-facing side of the first and second dry construction profiles 31 , 32. The dry construction structures depicted in Figs. 5 to 9b can be used in particular for ceilings and walls. In case of walls, the dry construction profiles 31 , 32 can form vertically arranged studs. The dry construction structures shown in Figs. 5 to 8 can also be fitted with the planking depicted in Fig. 9b.
