Abstract
Description
[Technical Field]
[0001] The rectangular metal elements used as members for drywall framing, i.e., runners (horizontal supports) and studs (vertical supports), can have different cross-sectional shapes, for example, U-shaped, C-shaped, or L-shaped. In the prior art, these metal elements are also called "profiles."
[0002] In some cases, drywall is erected to cover dead spaces or functional spaces, such as service ducts, electrical ducts, or the like. Particularly when these spaces are small, no inlet ports are provided. Therefore, once the wall or a part thereof is erected, it is no longer possible to enter or exit this dead room. It is therefore impossible to carry out any assembly work from behind the wall, i.e. from inside such a dead room.
[0003] According to the prior art, shaft drywall is installed by providing floor and ceiling runners that are substantially parallel to each other. U- or C-shaped studs, each with a base called a web and a side called a flange, located on either side of the base and perpendicular to the web, are fastened to a ceiling profile at the top and a floor profile at the bottom to form a stud frame. Generally, C-shaped studs are preferred over U-shaped studs due to their greater stability. The studs are positioned so that one flange is aligned parallel to the rear side of the drywall being constructed and fastened to the ceiling and floor profiles. The web is aligned perpendicular to the rear side, forming a spacer between the rear and front sides of the wall, and the second side is again aligned parallel to the rear side of the wall. Next, to construct the front cladding of the wall, a front panel can be attached to these front flanges of the studs.
[0004] However, due to the problems mentioned above, it is not possible to fasten the rear cladding to the rear side of the stud. As a result, for shaft drywall, the rear cladding is often simply omitted. However, this has several disadvantages. The disadvantage is that if an insulating material is desired as an interior component of the wall, there is no fixing tool for the insulation layer on the rear side. Furthermore, a second rear cladding is advantageous for fire and acoustic insulation reasons.
[0005] As a corrective measure, double U-studs (H-studs) are sometimes used instead of U-studs. H-studs can be achieved by fastening two U-studs back-to-back, or they can be manufactured as a single unit. Each H-stud has a flange on the right and left (whereas a U-stud only has a flange on one side). Drywall panels can then be applied, for example glued, to the inner surface of the rear flange of the studs. This process has the disadvantage that C-studs or double C-studs cannot be used because they have a "flap section" at the end of the flange and therefore do not provide a flat area for fastening panels on the inner rear surface. In addition, due to the lack of space inside the double U-profile, it is impossible to fasten these drywall panels by screwing, at least without considerable effort. Therefore, the covering material is fastened to the inside of the rear flange using adhesive, cement, or the like.
[0006] The above-mentioned procedure is not very easy and practical. There is no room for improvement, since the distance between the studs determines the size of the drywall panel, and vice versa. In addition, adhesion always poses a risk of separation, especially in the event of fire, flood, or the like, and it is not easy to apply the right amount of adhesive or cement and install the panel inside the studs, which are very difficult to access.
[0007] Therefore, there is a need to provide a stable and durable drywall that can be erected easily and comfortably. Preferably, when erecting the wall, access should be possible only from one side, i.e., the front side.
[0008] This problem can be overcome by the drywall, in particular shaft drywall, according to the main claim. Further independent claims refer to a process for erecting such drywall. Dependent claims refer to special advantageous embodiments of the drywall according to claim 1 and to special implementations of the process of the invention.
[0009] Thus, claim 1 refers to a drywall having a front side and a rear side, in particular a shaft drywall, which is arranged between two opposing boundary surfaces, comprising a first covering, also called a rear covering, of one or more drywall panel layers, and a second covering, also called a front covering, of one or more drywall panel layers.
[0010] A runner is provided on each bounding surface, with two runners disposed substantially parallel to one another. Each runner may be provided as a single runner element or as multiple runner elements. Each runner has an aft section extending substantially in a first plane and a front section extending substantially in a second plane (for clarity, the terms "first plane" and "second plane" herein refer only to the runners).
[0011] The drywall comprises a plurality of first building means, each having a rear section extending substantially in a first plane and a front section extending substantially in a second plane, the second plane preferably being substantially parallel to the first plane (for clarity, the terms "first plane" and "second plane" herein refer only to the first building means). The first building means are fixed by their rear sections to the rear section of the first runner, in particular to the inner surface of the rear section, and / or to the rear section of the second runner.
[0012] The first cladding is secured to the front section of the first construction means.
[0013] The drywall further comprises a plurality of second construction means, each having a rear section extending substantially in a first plane and a front section extending substantially in a second plane, the second plane preferably being substantially parallel to the first plane (for clarity, the terms "first plane" and "second plane" herein refer only to the second construction means).
[0014] The second construction means are positioned between the first cladding and the front sections of the runners, and advantageously, although not necessarily, the second construction means are fixed via their front sections to the front section of the first runner, in particular to the inner surface of the front section, and / or to the rear section of the second runner, in particular to the inner surface of the rear section.
[0015] The second cladding is secured to the front section of the second construction means.
[0016] Thus, the substantially planar front and rear sections of the runner, the first and second construction means may serve in particular to provide connection areas to their respective fixed counterparts.
[0017] Generally, in this specification and below, the terms "front", "front side", or the like, as well as "rear", "rear side", or the like, are used to distinguish between two opposite directions, i.e., the side on which the element under consideration or each of its parts or sections is located, or the direction in which its respective surface faces. In particular, the term "rear" refers here to the section, side, or surface facing towards the shaft (or, respectively, towards the dead space). The term "front" refers below to the section, side, or surface facing away from the shaft (or, respectively, the dead space). These terms do not necessarily imply that the respective element is the outermost element or part of the wall.
[0018] For example, "substantially," as in "substantially parallel," "substantially vertical," or "substantially horizontal," means that typical construction-related errors and deviations should not be interpreted as meaning that the corresponding embodiment will not be included in the respective specifications. The terms "extending substantially in a plane" and "substantially planar," as applied to geometric (area) elements or sections, mean that a particular plane may be assigned to the extent of the respective element or section viewed as a whole, but that some structures, grooves, notches, trim, edge lips, or the like may be present within the element or section. Similarly, if the respective geometric element or section has perforations, holes, recesses, punchings, or the like, it does not contradict the term "planar."
[0019] Preferably, the two opposing boundary surfaces are the ceiling and floor of a room, in particular a room of a house or another building. The two runners are preferably aligned substantially horizontally.
[0020] In a preferred manner, the drywall according to the invention is erected vertically, which preferably means that the front and back sides of the drywall are substantially parallel to each other.
[0021] A drywall according to the present invention can be a single drywall or part of a drywall system made up of more than one planar drywall. A single drywall extends in only one plane. A drywall system can be made up of two or more drywalls, each of which extends in a plane, with adjacent walls connected by a common edge and positioned at an angle to each other.
[0022] At the two outermost edges (left and right edges) of the drywall or each drywall system according to the present invention, there is generally a connection to a further wall (e.g., a boundary wall) of the respective room. Typically, at the connecting edge to the further wall, each wall edge is fastened by studs. These may be the same as the studs used for the wall construction, but may also be different studs. For example, U-shaped studs can also be used here.
[0023] When a runner is composed of more than one single runner element, these single runner elements are preferably aligned consecutively in a row. The runner elements that make up the runner can be U-shaped, for example, that is, they must have at least three substantially planar sections: a web and two flanges. Generally, the web serves to secure the runner to the respective boundary surfaces, while the flanges are used to attach the fastening elements. The flanges are preferably substantially perpendicular to the web. However, if the opposing boundary surfaces are not parallel to each other or if the drywall is to be placed at a slight incline rather than perpendicular, it may be advantageous for the angle between the web and flange of one or both runners to be different from 90°.
[0024] In one embodiment, the first and / or second building means may be relatively short metal elements, with hat-shaped metal elements being particularly preferred as they provide substantially planar front and rear sections.
[0025] Advantageously, the drywall comprises at least one stud system. Preferably, the first and / or second construction means are therefore designated as studs extending between two runners. Preferably, both the first and second construction means are studs. In the following, when designated as studs, the first construction means will be called first studs and the second fastening elements will be called second studs.
[0026] Preferably, the first stud is positioned substantially perpendicular to the runner. More preferably, the second stud is also positioned substantially perpendicular to the runner, and in particular substantially parallel to the first stud. Very preferably, both the first stud and the second stud extend substantially perpendicularly between the two runners.
[0027] Preferably, the first construction means, in particular the first studs, are spaced equidistant from one another and / or the second studs are spaced equidistant from one another. In a preferred example, the distance between each of two adjacent first studs and / or two adjacent second studs may be 625 mm.
[0028] Preferably, the number of first studs and the number of second studs are equal, and preferably, when viewed from the front of the drywall, there is always one of the first studs and one of the second studs aligned with each other (making up each "pair" of first and second studs).
[0029] However, other stud arrangements are possible, such as having non-equidistant first and / or second studs (as viewed from the front of the drywall) and / or different numbers of first and second studs and / or staggered first and second studs. It is also possible for some of the first studs to be aligned with some of the second studs and some to be staggered.
[0030] Advantageously, the first stud is hat-shaped (each metal element is also known as a hat profile or hat profile rail). A hat-shaped stud has a base section, or web, two side sections, or flanges, each arranged at an angle to the web and generally substantially perpendicular to it, and two outward sections, referred to herein as "collar sections", at the flange edges facing away from the web, which are substantially flush with each other and substantially parallel to the web. Preferably, the web, flanges and collar sections are each substantially planar.
[0031] In particular, a special embodiment of a hat-type stud having multiple hole punchings in the flange area can be selected as the first stud. Such studs are also known as "spring rails".
[0032] In particular, the web of the hat-shaped stud (as described above) serves as the front section, and the collar section serves as the rear section of the first stud. Thus, here the collar section of the first stud is attached to the runner, and in particular the outermost parts of the collar section at the two ends of the stud are fastened to the runner at two interface surfaces, in particular to the flanges of the runner, in order to fix the studs in their respective positions. The web of the first stud is attached to the rear side of the rear cladding. Preferably, all attachments are screw attachments. Due to the special shape of the first stud, the screwing of the collar section of the first stud to the runner and the screwing of the rear cladding to the web of the first stud can both be performed from the front side.
[0033] Generally, it is also possible to position the hat studs inside out, i.e. with the collar section secured to the rear cladding and the web secured to the runner.
[0034] In another embodiment of the drywall of the present invention, the first stud can be a C-shaped stud, in particular a so-called CD stud. The C-shaped first stud can be fixed to the runner by a suitable fixing clip ("indirect fixing"). These C-shaped studs include a base section, i.e., a web, two side surfaces, i.e., flanges, arranged at both ends of the web at an angle, preferably substantially perpendicular to the web, and two inward sections at the flange edges opposite the web, referred to herein as "flap sections." Fixing clips for fixing CD studs or CD runners to surfaces or to other studs or runners are known in the prior art. Herein, such fixing clips are preferred, as they allow the stud to be fixed to the runner only by cribbing, without using screws.
[0035] If the back cladding comprises two or even more drywall panel layers, the panel layers may be fastened to the first construction means, in particular to the first studs, by long screws passing through all layers, and / or the first panel layer may be screwed to the first stud, the second panel layer to the first panel layer, etc. and / or it is possible to have long screws that pass through all panel layers and terminate in the first stud, with screws that only secure the first panel layer to the second stud and / or the panel layers to each other.
[0036] Special drywall screws are commercially available and are suitable for the present invention.
[0037] The second studs may be U-shaped, but advantageously they are C-shaped (including their layout as CW studs). Preferably, the flap sections are substantially parallel to the web and coplanar with each other. Preferably, the web, flange, and flap sections are each substantially planar.
[0038] The fixation of the second studs in the drywall according to the present invention can be achieved only by the second cladding attached to them and, if applicable, by clamping the second studs between the first cladding and the front section of the runner (form fit). Preferably, however, the front section of the second studs is fastened to the front section of the runner to improve the stability of the drywall. Preferably, the second studs are attached to the front section of the runner by crimping and / or by screwing.
[0039] Generally, the secondary studs will be adjacent to the primary (rear) cladding by their rear sections. For better separation characteristics, it is advantageous to provide a seal at the interface between the secondary studs and the primary cladding. For example, before installing these secondary studs, a sealing tape can be glued onto the outer surface of the front section of the primary cladding. It is also possible to provide the sealing material only in sections where, for example, sealing tape segments are glued within a certain distance and there is a space between them without sealing. Even if the sealing is not continuous, it still provides good separation.
[0040] Because the second stud is not fastened directly to the first cladding, isolation properties are optimized.
[0041] In a preferred manner, the second studs may be positioned so that all of the openings in the studs face the same direction, particularly to the left or right when viewed from the front side of the drywall, although this is not necessarily the case.
[0042] If the front cladding includes two or more drywall panel layers, the panel layers may be fastened to the second studs by long screws that pass through all layers; and / or the first panel layer may be screwed to the second stud, the second panel layer to the first panel layer, etc. and / or it may have long screws that pass through all panel layers and terminate in the second stud, with screws that only secure the first panel layer to the second stud and / or the panel layers to each other.
[0043] Again, special drywall screws are commercially available and suitable for the present invention.
[0044] The first and / or second stud are generally made of metal, for example aluminium, and particularly preferably made of steel.
[0045] If desired, an insulating material may be inserted into the interior space between the two claddings, and generally this will be done before the front cladding is installed. The insulating material may be selected according to its known purpose.
[0046] Furthermore, if desired, it is possible to lay cables or install ducts, pipes, or the like within the interior space between the two coverings. For example, if the shaft drywall separates a duct shaft or another type of damp room (e.g., a bathroom), it may be advantageous to insert electrical cables within the drywall itself.
[0047] Another aspect of the present invention is to provide a process for erecting drywall, particularly shaft drywall.
[0048] The process according to the present invention comprises the following steps: (a) attaching runners to one of two opposing boundary surfaces, each runner having a rear section and a front section, and attaching a runner to the other of the two opposing boundary surfaces; (b) attaching a plurality of first construction means, in particular first studs, each of which has a rear section and a front section, to the rear sections of the two runners at their rear sections; (c) attaching at least one panel layer to the front section of the first construction means to construct a first cladding; (d) positioning a plurality of second construction means, in particular second studs, each second construction means having a rear section and a front section, between the first cladding and the front sections of the two runners; (e) attaching at least one panel layer to the front section of the second construction means to construct a second cladding.
[0049] The second construction means is therefore positioned between the first cladding and the front section of the runner. In particular, if studs are used as the second construction means, it may be sufficient to simply insert the second construction means between the first cladding and the front section of the runner, and then attach the second cladding to achieve final fixation of the second construction means, in particular the second studs. If the width of the runner is selected according to the dimensions of the first cladding and the second studs, the second studs may be inserted so that they are held in place by a clamping effect. If insulating material is inserted into the interior space between the two claddings, this may help to hold the second construction means in place during the erection of the drywall.
[0050] Advantageously, however, in optional step (d2), the second building means are fastened via their front sections to the front section, in particular the inner surface of the front section, of the first runner and / or to the rear section, in particular the inner surface of the rear section, of the second runner. Step (d2) can be carried out simultaneously with step (d) or subsequently.
[0051] The process according to the invention allows all fastening to be carried out from the front side. Thus, at least steps (c) to (e), preferably (b) to (e), are carried out from the front side. Advantageously, steps (a) and (b) are not yet obstructed by the first covering obtained, but all steps (a) to (e) are carried out from the front side, i.e. by a person standing in front of the drywall being constructed. According to processes as known in the art, no further access to this back side was possible during these processes, so it was not possible to fasten all layers and components of such drywall, such as by crimping and / or screwing.
[0052] If the first building means are first studs and / or the second building means are second studs, each of these studs preferably extends between two runners.
[0053] Preferably, the steps are performed in the order described above, but it is generally possible to have a different sequence of steps, for example, first attaching the first studs to the two runners to build the frame, and then attaching the two runners, i.e. the frame, to the two opposing boundary surfaces.
[0054] Preferably, the two opposing bounding surfaces are the ceiling and floor of a room.
[0055] Preferably, the drywall as erected by the above process corresponds to the specifications as given for the drywall according to the invention and its design, as described above.
[0056] In the drywall available through this method, the first cladding is the rear cladding and the second cladding is the front cladding.
[0057] Optionally, in step (c), a series of more than one panel layer is attached to the front section of the first stud, and / or in a further step (c1) following step (c), at least one further panel layer is fixed onto the panel layer attached to the stud in step (c), thereby obtaining a multi-layer first cladding material.
[0058] Also optionally, in step (e), a series of more than one panel layer is attached to the front section of the second stud, and / or in a further step (e1) following step (e), at least one further panel layer is fixed onto the panel layer attached to the stud in step (e), thereby obtaining a multi-layer second cladding material.
[0059] Preferably, a seal is provided between the rear sections of the second studs and the adjacent surface of the rear cladding. Advantageously, this is achieved by adhering a sealing tape to the outer surface of the rear sections of the second studs before installing the second studs, i.e. before attaching them to the front section of the runner in step (d). Alternatively, or in addition, a sealing layer or sealing tape may also be provided on each surface of the rear cladding before installing the second studs.
[0060] A runner can be a single metal element (single runner) or can consist of more than one runner element. When multiple elements are used to construct a runner, it is preferable that they are arranged in a row, aligned one after the other. In one way of implementing a runner, adjacent runner elements touch each other via a common abutment edge, so that there is at least one continuous attachment area (one of the flanges) for the first studs. However, in this specification, the term runner also includes runner systems in which there is a distance between successive elements, as long as the available flanges allow all first studs to be fastened in the desired manner. This can save material.
[0061] Preferably, the attachment of the first construction means, in particular the first stud, to the runner in step (b) or the attachment of the second construction means, in particular the second stud, to the runner in step (d2), or both, is achieved by crimping the parts together (i.e. by a crimp connection) and / or by screwing them together (i.e. by a screw connection).
[0062] In particular, when fastening the second stud to the runner in step (d2), which generally means fastening the front section of the second construction means to the inner surface of the front section of the runner, crimping is very advantageous, since this can be easily done from the front side of the drywall to be erected.
[0063] More preferably, the attachment of the panel layer(s) to the first construction means, in particular to the first studs, in step (c) and / or step (c1), and / or the attachment of the panel layer(s) to the second construction means, in particular to the second studs, in step (e) and / or step (e1), and / or both of these attachments are achieved by screw fastening.
[0064] Certain features as described above for drywall shall also be transferred to the process as advantageous features to avoid duplication.
[0065] The process allows the drywall to be erected by working from the front side of the resulting drywall, as all steps can be carried out from this side. Compared to prior art shaft drywalling, a simple and effective process is provided, allowing for secure fastening at all steps. Adhesion etc. can be avoided.
[0066] Furthermore, the drywall according to the invention and / or obtained by the process according to the invention has excellent acoustic absorption properties, since the second construction means, in particular the second studs, are fixed only to the runners and not to the first cladding, meaning that there are two cladding layers that are substantially acoustically separated from each other.
[0067] The present invention will be explained in more detail with reference to Figures 1 to 7. It is noted that it is not intended to unnecessarily limit the scope of the invention to the illustrated embodiments. [Explanation of symbols]

[0069] [Figure 1] It shows primarily the general design of a hat-type stud that can be used as the first construction means 1. The stud has a base section 12, or web, two side sections 13, or flanges, each arranged at an angle to the web and generally substantially perpendicular to it, and two outward sections 11, or collar sections, at the flange edges facing away from the web, that are substantially flush with each other and substantially parallel to the web. [Figure 2] The general design of a C-shaped stud that may be used as the second construction means 2 is shown, comprising primarily a base section 23, i.e., web, two side sections 21, 22, i.e., flanges, arranged at angles to either end of the web, preferably substantially perpendicular to the web, and two inward sections 24, i.e., "flap sections", at the flange edges opposite the web. [Figure 3a]The illustrated example primarily shows a runner 3 consisting of more than one single runner element 31, 32, 33 (although the figure indicates that a greater number of runners could follow). In Fig. 3a, the runner 3 is attached to the ceiling 7, whereas in Fig. 3b, the runner 3 is attached to the floor 8. The size relationships are not to scale and, generally, the single runner elements will be somewhat longer as shown here. According to this example, each single runner element 31, 32, 33 is a U-shaped metal element comprising a web 34 and two flanges 35, 36. The single runner elements 31, 32, 33 abut at abutting edges 37 and are arranged one after the other in a line. As already explained above, it is alternatively possible to provide spacing between the single elements. [Figure 3b] The illustrated example primarily shows a runner 3 consisting of more than one single runner element 31, 32, 33 (although the figure indicates that a greater number of runners could follow). In Fig. 3a, the runner 3 is attached to the ceiling 7, whereas in Fig. 3b, the runner 3 is attached to the floor 8. The size relationships are not to scale and, generally, the single runner elements will be somewhat longer as shown here. According to this example, each single runner element 31, 32, 33 is a U-shaped metal element comprising a web 34 and two flanges 35, 36. The single runner elements 31, 32, 33 abut at abutting edges 37 and are arranged one after the other in a line. As already explained above, it is alternatively possible to provide spacing between the single elements. [Figure 4]4 shows a detailed view of the fastening of the hat stud 1 (first construction means) to the runner 3. The collar section 11 of the hat stud 1 can be fixed inside the rear flange 35 (rear section) of the runner 3, for example, by means of a self-tapping screw 41. Figure 4 further shows that a certain plane can be applied to the web 34 and flanges 35, 36 of the runner 3, as well as to the web 11, flange 13 and collar section 12 of the hat stud 1 (the same applies to the section of the C-stud, not shown in this figure), regardless of whether this is slightly modified by a groove 71, an end lip 72 or the like. [Figure 5]5 shows a cross-section of an example of a shaft drywall according to the present invention, in which the first construction means 1 are studs, i.e. hat-type studs, the second construction means 2 are also studs, i.e. C-type studs, and the two opposite boundaries are the ceiling 7 and floor 8 of a room. FIG. 5 shows a horizontal cross-section (view from above) through the drywall according to the present invention. In this figure, the rear side of the drywall (e.g., the shaft side of the shaft drywall) is at the top of the drawing, and the front side of the drywall (e.g., the freely accessible side of the shaft drywall) is at the bottom. FIG. 6 shows a vertical cross-section (side view) through the drywall according to the present invention. In this figure, the rear side of the drywall (e.g., the shaft side of the shaft drywall) is on the right-hand side, and the front side of the drywall (e.g., the freely accessible side of the shaft drywall) is on the left-hand side. Subsequently, both figures, FIG. 5 and FIG. 6, will be explained together. Two U-shaped runners 3 (only one of which is shown by its flange edge in Figure 5, top view) are fixed to the ceiling 7 and floor 8 of the room by wall nails 62. The two ends of the hat-shaped studs 1 (first construction means) are each fixed via their rear sections 11, or collar sections, to the inner surface of the rear section 35, or rear flange, of the ceiling and floor runner 3 by self-tapping screws 41. To build the first (rear) cladding 4, a panel layer is fixed to the front section 12, or web, of the first stud 1 by drywall screws 42. The rear side of the front cladding 4 is therefore adjacent to the front section 12, or web, of the first stud 1. The second studs 2 are fixed to the front section 36, or front flange, of the runner 3 by crimping 43; more precisely, the front sections 22, or flanges, at both ends of each second stud 2 are crimped to the inner surface of the front section 36, or front flange, of the runner 3. The dimensions of the web 34 of the runner 3 are selected so that the rear section 21, i.e., rear flange, of the stud 2 is adjacent to the front face of the rear cladding 4. Sealing tape 44 is provided at the interface between the rear cladding 4 and the rear section 21 of the second stud 2. To construct the second (front) cladding 5, two panel layers 51, 52 are attached by drywall screws 42 at the front section 22, i.e., front flange, of the second stud 2.In the gap between the two cladding materials 4, 5, an insulating material 9 is inserted (placed between second studs 2 also positioned in this gap). At the drywall end, a U-shaped stud 61, itself fixed by a wall nail 62, ensures the fastening of the drywall to the adjacent wall 6 of the room. A respective sealing 63 is provided at the drywall end. [Figure 6]5 shows a cross-section of an example of a shaft drywall according to the present invention, in which the first construction means 1 are studs, i.e. hat-type studs, the second construction means 2 are also studs, i.e. C-type studs, and the two opposite boundaries are the ceiling 7 and floor 8 of a room. FIG. 5 shows a horizontal cross-section (view from above) through the drywall according to the present invention. In this figure, the rear side of the drywall (e.g., the shaft side of the shaft drywall) is at the top of the drawing, and the front side of the drywall (e.g., the freely accessible side of the shaft drywall) is at the bottom. FIG. 6 shows a vertical cross-section (side view) through the drywall according to the present invention. In this figure, the rear side of the drywall (e.g., the shaft side of the shaft drywall) is on the right-hand side, and the front side of the drywall (e.g., the freely accessible side of the shaft drywall) is on the left-hand side. Subsequently, both figures, FIG. 5 and FIG. 6, will be explained together. Two U-shaped runners 3 (only one of which is shown by its flange edge in Figure 5, top view) are fixed to the ceiling 7 and floor 8 of the room by wall nails 62. The two ends of the hat-shaped studs 1 (first construction means) are each fixed via their rear sections 11, or collar sections, to the inner surface of the rear section 35, or rear flange, of the ceiling and floor runner 3 by self-tapping screws 41. To build the first (rear) cladding 4, a panel layer is fixed to the front section 12, or web, of the first stud 1 by drywall screws 42. The rear side of the front cladding 4 is therefore adjacent to the front section 12, or web, of the first stud 1. The second studs 2 are fixed to the front section 36, or front flange, of the runner 3 by crimping 43; more precisely, the front sections 22, or flanges, at both ends of each second stud 2 are crimped to the inner surface of the front section 36, or front flange, of the runner 3. The dimensions of the web 34 of the runner 3 are selected so that the rear section 21, i.e., rear flange, of the stud 2 is adjacent to the front face of the rear cladding 4. Sealing tape 44 is provided at the interface between the rear cladding 4 and the rear section 21 of the second stud 2. To construct the second (front) cladding 5, two panel layers 51, 52 are attached by drywall screws 42 at the front section 22, i.e., front flange, of the second stud 2.In the gap between the two cladding materials 4, 5, an insulating material 9 is inserted (placed between second studs 2 also positioned in this gap). At the drywall end, a U-shaped stud 61, itself fixed by a wall nail 62, ensures the fastening of the drywall to the adjacent wall 6 of the room. A respective sealing 63 is provided at the drywall end. [Figure 7] An example of an intermediate state of the process according to the invention, i.e. a frame, is shown, in which a number of first construction means 1, i.e. first hat-shaped studs, are attached to two horizontally aligned parallel runners 3, which are attached to the ceiling 7 and to the floor 8 of a room. The first studs 1 are spaced equidistant from each other. On the left and right sides, further studs 61 (U-shaped) are present for fastening to the adjacent walls 6. The frame is ready for the attachment of the first panel layer and subsequent drywall components and layers. [Figure 8] Figure 1 shows a schematic perspective view of a drywall according to the invention, comprising a plurality of first building means 1 in the form of hat-shaped studs, a plurality of second building means 2 in the form of C-shaped studs, runners 3 on the floor and ceiling (the latter not shown), a first cladding 4 between the first building means 1 and the second building means 2, and a second cladding 5 fixed on the second building means 2. U-shaped studs 61 are used for attaching the side walls.
