Description

[0045] Further goals, characteristics, advantages and application possibilities of this invention result from the following description of exemplary embodiments based on the drawings. All described and/or depicted characteristics, individually or in any meaningful combination, form the object of the invention, also independently of the summary in individual claims or their back references.

[0046] The figures show:

[0047] FIG. 1: a first embodiment of a drywall in front view;

[0048] FIG. 2: the enlarged detail II from the drywall of FIG. 1;

[0049] FIG. 3: a perspective representation of a second embodiment of a drywall;

[0050] FIG. 4: the enlarged detail III from the drywall of FIG. 3;

[0051] FIG. 5: the enlarged detail IV from the drywall of FIG. 3.

[0052] FIG. 1 shows a first embodiment of a drywall 1. In order to be able to display the structure of the drywall 1, the drywall 1 is shown without paneling.

[0053] The drywall 1 comprises a support structure 2, which comprises first stud elements 3. The first stud elements 3 are arranged in a row with first distances and form first support structure bays 4. The first stud elements 3 are arranged vertically. In each case, two first stud elements 3 delimit a first support structure bay 4 that is positioned between them.

[0054] The first stud elements 3 are arranged in a first wall section 5 of the drywall 1. The drywall 1 also has second wall sections 6, 6′, in each of which an installation duct 7 is arranged. In the area of the second wall sections 6, 6′, the support structure 2 has a first crossbeam 8 and a second crossbeam 9, respectively. These form second support structure bays 10, 10′, which in each case extend across several first support structure bays 4 arranged next to each other. In this way, an integrated, continuous installation duct 7 is created in the area of each of the second support structure bays 10, 10′, so that installations can be arranged inside the drywall 1. The depicted embodiment shows that installations with a larger space requirement can be accommodated inside the drywall 1.

[0055] The drywall 1 also has a third wall section 11, whereby the support structure 2 has second stud elements 12 in the area of the third wall section 11. These are arranged vertically in a row next to each other with second distances between the individual stud elements 12. Third support structure bays 27 are formed between the second stud elements 12. In the example shown here, the distances between the first stud elements 3 and the second stud elements 12 are equal. The second stud elements 12 are aligned with the first stud elements 3.

[0056] FIG. 1 further shows that the second wall section 6 is located between the first and third wall sections 5, 11. In the embodiment shown, the second support structure bay 10 extends across the entire width of the wall. The second wall section 6′ is arranged under the first wall section 5. The second support structure bay 10′ is slightly shorter.

[0057] In each case, the first crossbeam 8 is located on the bottom side of the installation duct 7, while the second crossbeam 9 is located on the upper side of the installation duct 7.

[0058] The second stud elements 12 are arranged standing on the second crossbeam 9 of the second wall section 6. The first stud elements 3 are arranged standing on the second crossbeam 9 of the second wall section 6′ or in a floor rail.

[0059] The first and second crossbeams 8, 9 are arranged horizontally.

[0060] In the embodiment shown in FIG. 1, the first and second crossbeams 8, 9 are each connected at their ends with an adjacent component 13 in a load-bearing manner. In this way, the crossbeams 8, 9 can absorb the occurring forces and transfer them to the adjacent component 13. In the embodiment shown, the load-bearing component 13 is only shown schematically. The load-bearing component 13 can, for example, be the wall of a building, the pillar of a building, a continuous stud or the like.

[0061] The first and second stud elements 3, 12 and the first and second crossbeams 8, 9 may be made of wood, steel or any other sufficiently strong material. In the embodiment shown, the first and second crossbeams 8, 9 each have a first metal crossbeam profile 14. The first crossbeam profile 14 may have a first crossbeam profile web 15 (see FIG. 2) and two first crossbeam profile flanges 16 arranged thereon. In the embodiment shown, the first crossbeam profile 14 is formed as a U channel. The first crossbeam profile 14 can be formed as a U stiffening channel (also known as a UA channel). Compared to a U wall channel (also known as a UW channel), it has an increased load-bearing capacity. Accordingly, the first crossbeam profile 14 has a material thickness of between 1 mm and 5 mm, whereas the first and second stud elements 3, 12 has a material thickness of between 0.4 mm and 1 mm.

[0062] The first and second crossbeam 8, 9 in the embodiment shown in FIG. 1 each also comprise a second crossbeam profile 17. The second crossbeam profile 17 is made of metal and each has a second crossbeam profile web 18 and two second crossbeam profile flanges 19 arranged thereon.

[0063] The first and second crossbeam profiles 14, 17 are arranged on top of each other, with the first and second crossbeam profile webs 15, 18 abutting each other and the first and second crossbeam profile flanges 16, 19 pointing in opposite directions. Thus, the first and second crossbeam profiles 14, 17 are arranged “back to back”. Preferably, the second crossbeam profile 17 is formed as a U channel. Since in the embodiment shown, the first crossbeam profile 14 assumes a load-bearing function, it is sufficient for the second crossbeam profile 17 to be formed as a U wall channel and to have a material thickness of between 0.4 mm and 1 mm.

[0064] FIG. 1 further shows that the second crossbeam profiles 17 in the area of the second wall section 6 are arranged such that the second crossbeam profile flanges 19 point to the first support structure bays 4 and to the third support structure bays 27 respectively. In this way, the first stud element 3 can be accommodated between the second crossbeam profile flanges 19. The second crossbeam profiles 17 are provided in order to allow to slideably insert the first and second stud elements 3, 12 between its flanges which would not be possible with the stronger U channels 14 due the inflexibility of its flanges and its inner dimension. The inner dimension of the U channels 14 is smaller than in the same size second crossbeam profiles 17 due to their higher material thickness.

[0065] Similarly, in the area of the third wall section 11, the second crossbeam profile 17, which is arranged on the second crossbeam 9, is arranged in such a way that the lower ends of the second stud elements 12 are received between the second crossbeam profile flanges 19.

[0066] The first and second crossbeam profiles 14, 17 can be joined together with fasteners, such as screws, nails, brackets, glue or the like.

[0067] FIG. 1 further shows that below the lower second wall section 6, a fourth wall section 20 is formed which extends parallel to the second wall section 6. Here, too, there is a cavity that can be used for installations.

[0068] The first and second stud elements 3, 12 are formed as metal stud profiles in the embodiment shown, each of which has a stud profile web and stud profile flanges arranged thereon. The stud profiles can in particular be C wall channels (also referred to as CW channels). The material thickness of the stud profiles can be between 0.4 mm and 5 mm, whereby a material thickness of 0.5 mm to 1 mm is generally sufficient for drywalls, which do not have a load-bearing function in a building. However, the metal stud profiles can also have other cross-sectional shapes, such as a U, or M channel in particular.

[0069] In the second wall sections 6, 6′, there is sufficient space to arrange installations, such as electrical lines, water lines, sewage lines, ventilation lines, supply lines and/or coolant lines, invisibly inside the drywall 1. It is advantageous that the installation lines in this area do not have to be threaded through openings in the profiles, whereby they can be damaged.

[0070] FIG. 2 shows the enlarged detail II from FIG. 1 in perspective view. In particular, it is shown that the first and second crossbeams 8, 9 each have a first and a second crossbeam profile 14, 17. In addition, the arrangement of the first and second crossbeam profiles 14, 17 “back to back” can be clearly seen.

[0071] Furthermore, FIG. 2 shows how the first and second crossbeams 8, 9 are attached to one side of the load-bearing component 13 by brackets or angles 22. A corresponding fastening is provided on the opposite side of the drywall 1.

[0072] FIG. 2 also shows that the upward pointing first crossbeam profile flanges 16 of the first crossbeam 8 form a space in which installations, such as electrical cables and the like, can be arranged horizontally. The first crossbeam profile flanges 16 not only ensure that the installations remain in the desired position, they also protect them from damage at the same time. When electrical cables are to be installed in this channel a plastic lining is advisable in order to prevent short-cuts from damaged cables.

[0073] The support structure 2 shown in FIGS. 1 and 2 can be fitted with a paneling, which comprises planking panels, in the usual way. The planking panels can be in particular gypsum boards, gypsum plasterboards, gypsum fibreboards or fibre-cement boards. The planking panels can be connected with fasteners, such as screws, to the first and second stud elements 3, 12 as well as to the first and/or second crossbeam profiles 14, 17. Preferably, they are fixed to the second crossbeam profiles 17 which have a lower material gauge. The paneling stiffens the drywall 1, so that despite the continuous horizontal second wall sections 6, 6′ with the installation ducts 7, a high stability of the drywall 1 results. The embodiment shown in FIGS. 1 and 2 with paneling on one side is particularly suitable as a facing shell in front of existing walls. However, it can also be used as a partition wall with paneling on both sides.

[0074] FIGS. 3 to 5 show another embodiment of the invention. Since it has substantial similarities with the embodiment from FIGS. 1 and 2, the same reference signs are used for parts with the same function. Where there are similarities, the description of FIGS. 1 and 2 shall apply accordingly to FIGS. 3 to 5.

[0075] The embodiment shown in FIGS. 3 to 5 differs from that shown in FIGS. 1 and 2 in that the support structure 2 has a first row of studs 23 and a second row of studs 24. In the first row of studs 23, the first and second stud elements 3, 12 with the first and second crossbeams 8, 9 are arranged as described in connection with FIGS. 1 and 2. In the second row of studs 24, the support structure 2 has additional third stud elements 25. The third stud elements 25 extend continuously across the entire height of the drywall 1 and thus also cover the first, second and third wall sections 5, 6, 6′, 11. The third stud elements 25 give the support structure 2 additional stability. It is therefore not necessary to attach the first and second crossbeams 8, 9 laterally to a load-bearing component 13, as shown in FIG. 2. This allows drywalls to be constructed in any width and it is not necessary for the first and second crossbeams to be so long that they can cover the entire wall width without interruption. The embodiment shown in FIGS. 3 to 5 thus provides additional flexibility, although the two-layer design of the support structure 2 results in a somewhat greater minimum wall thickness. This embodiment is particularly suitable as a partition wall with paneling on both sides.

[0076] The third stud element 25, like the first and second stud elements 3, 12, can be formed as metal stud profiles. Reference is made to the above description of the stud profiles, which also applies to the third stud elements 25.

[0077] The first and second stud elements 3, 12 are arranged directly next to the third stud elements 25, almost abutting but preferably not actually contacting them. The first and third stud elements 3, 25 and the second and third stud elements 12, 25, respectively, are aligned parallel to each other. The first and second stud elements 3, 12 are each statically connected to an adjacent third stud element 25. In the embodiment shown, panel strips 26 are provided for connection. These can be, for example, strips of planking panels. The planking strips 26 connect the first and third stud elements 3, 25 and the second and third stud elements 12, 25, respectively, arranged next to each other. If the stud elements are metal profiles, the profiles are preferably arranged in such a way that the flanges of both studs are next to each other.

[0078] Furthermore, FIG. 3 shows that the first crossbeam 8 of the second support structure bay 10 has a first and a second crossbeam profile 14, 17. The second crossbeam 9, on the other hand, has only the first crossbeam profile 14. Since in the embodiment shown in FIGS. 3 to 5, the support structure 2 is given additional stability by the third stud elements 25, U wall channels with a lower material thickness can be used for the first and second crossbeams 8, 9. The U stiffening channels, which have a greater material thickness and thus a higher load-bearing capacity, are generally not required, but can also be used.

[0079] In addition to the upper installation duct 7, the embodiment shown in FIG. 3 also has a lower installation duct 7′. In case of the lower installation duct 7′, the first crossbeam 8 does not have a second crossbeam profile 17.

[0080] FIG. 3 also shows in a section on the left how a two-layer paneling 28 can be arranged on the support structure 2. The position of fasteners 29, which e.g. could be formed as screws, is also shown schematically. In the finished state, the drywall 1 is on both sides completely covered with two layers of paneling 28 each.

[0081] FIGS. 4 and 5 show the sections III and IV of the drywall 1 from FIG. 3. Here, the double stud design of the support structure 2 can be clearly seen, having the first and third and second and third stud elements 3, 12, 25, respectively, arranged next to each other, forming double studs. The connection of the stud elements 3, 12, 25 with the panel strips 26 is also shown. FIGS. 4 and 5 also show how an installation, such as an electrical cable 30, can be arranged inside the drywall 1. The double stud design has the advantage that installations can also be guided vertically without any problems because the installation duct 7 is only present in one half of the interior space of the drywall 1. In the other half, the installation can easily be guided laterally past the crossbeams 8, 9.

[0082] Furthermore, FIG. 4 shows that the first and third stud elements 3, 25 can be accommodated at their lower ends in U rails 31. U rails 31 can also be provided at the upper end of the drywall 1 in typical manner.

[0083] FIG. 5 again clearly shows the double stud construction of the drywall 1, whereby the first and second stud elements 3, 12 and the crossbeams 8, 9 are located in the first row of studs 23. In the second row of studs 24, the continuous third stud elements 25 are provided. In FIG. 5 however, the second row of studs 24 is behind the first row of studs 23.

[0084] Furthermore, it is shown how the first and the second crossbeams 8, 9 are arranged. The first crossbeam 8 comprises, as described above, a first and a second crossbeam profile 14, 17, which are formed as U channels. The orientation of the U channels is illustrated by dashed lines. It is also shown that the upper ends of the first stud elements 3 are accommodated between the first crossbeam profile flanges 16. The U channel 17 serves as a receiving element and guide for the installation 30. It is formed from plastic.
