Description

[0001] The invention relates to a mounting module for mounting a cistern and a method for realizing a pre-wall in front of such a mounting module as well as a method for realizing a WC installation with a WC body installed on a front side of a pre-wall.

[0002] Generic mounting modules are widely known in the art and are mostly used to mount a cistern behind a pre-wall. The mounting module extends along a vertical line with a height and along a transversal line with a width and forms a front side, with the pre-wall usually being arranged on the front side of the mounting module extending along the vertical and transversal lines. The pre-wall can have openings through which elements of the mounting module extend, so that the pre-wall is only arranged in front of sections of the front side of the mounting module and further sections of the mounting module extend in front of the pre-wall, so that they form pre-wall side sections of the mounting module, which are arranged in front of the pre-wall.The term "front" always refers to the side of the mounting module to which a toilet body is intended to be attached to the mounting module and which is viewed from a direction perpendicular to the vertical and transverse. To secure the toilet body, the mounting module typically has fastening rods that are firmly mounted to a module frame of the mounting module and onto which the toilet body can then be pushed. The fastening rods are inserted into corresponding openings in the toilet body. After this, the toilet body is finally fastened to the fastening rods by means of fixing devices corresponding to the fastening rods, for example, comprising a nut and / or a clamping unit.A cistern typically comprises an actuating device for triggering a toilet flush, which is usually integrated into a cover plate that closes a reversing opening provided in the cistern. Assembly modules of this type typically comprise a module frame, a drain pipe, and a cistern with a flush pipe. In an operating position of the assembly module, the cistern is attached to the module frame, and the flush pipe forms a flush pipe connection open at the front of the assembly module, and the drain pipe is attached to the module frame and forms a drain pipe connection open at the front of the assembly module. The operating position refers to a specific arrangement of the components of the assembly module relative to one another.In the operating position, the flush pipe connection and the drain pipe connection of the mounting module are accessible from the front, so that in the operating position of the mounting module, a toilet body with its flush water inlet connection and its waste water outlet connection can be connected to the flush pipe connection and the drain pipe connection from the front of the mounting module.

[0003] Generic mounting modules are suitable for the particularly simple installation of a toilet. The provision of the module frame, which usually has at least two vertically running support struts and at least two transverse struts connecting the support struts, enables easy installation of the cistern and a toilet body in a room. This is because the module frame can be placed with its vertical underside on a room floor and fixed to the room floor and in particular to a wall bordering the room, for example the supporting structure for a drywall or a building wall, so that a cistern fixed to the module frame and a toilet body fixed to the module frame can be arranged in a simple and reliable manner in a room.At the same time, by attaching the flush pipe and the drain pipe to the module frame, the module frame can reliably determine the positions of these pipes in the operating position. The drain pipe, which is attached to the module frame, typically opens into a building-side sewer line at its vertically lower end. After the drain pipe of the assembly module has been connected to the building-side sewer line and the cistern has been connected to at least one building-side water supply line and, in particular, also to a building-side electrical supply line, a prefabricated wall can then be created in front of the module frame and thus at least partially in front of the assembly module. Such a prefabricated wall is usually realized as a drywall.The pre-wall comprises a building board, for example a plasterboard, and UW and CW profiles are usually used as the supporting framework for the pre-wall, to the front of which the building boards of the pre-wall are mounted. Generic mounting modules usually have a module frame that can be arranged in such UW or CW profiles. Generic mounting modules thus enable reliable fixing and connection of a cistern before the pre-wall is erected. This means that after completion of the pre-wall, which usually includes building boards as well as tiles attached to the front of the building boards, a toilet body can be mounted on the front of the pre-wall and can be easily connected to the cistern's flush pipe connection and the drain pipe connection.

[0004] Such assembly modules must therefore remain in a room for an extended period during the construction period, after the drainpipe and cistern have been connected to the corresponding building pipes or pipe connections. This is because various trades are usually active at this time, such as floor fitters, drywallers, tilers, electricians, etc. Such assembly modules must therefore be able to allow the subsequent connection of a toilet body without damage during this construction period and, in addition, protect access to building connections, for example, to prevent unpleasant odors from escaping from the building's sewer line or the entry of contaminants into such a sewer line during the construction period.Furthermore, such installation modules should enable the simplest and safest possible connection of the toilet body after the pre-wall and, in particular, the floor have been installed in a room. Generic installation modules only partially meet these requirements. For example, it is known to supply installation modules with covers that can be attached to the flush pipe connection and the drain pipe connection. While this can generally prevent damage to the drain pipe connection and flush pipe connection, as well as the ingress of contaminants into these connections and the escape of unpleasant odors, such covers only inadequately ensure the simple completion of the pre-wall in a way that subsequently ensures the most universal connection of any toilet body.It should be noted that toilet bowls with a wide variety of functions are available on the market today, for example, with additional features such as a hygienic flush, odor extraction, or a drying fan. Different toilet bowls require different wall connections, but providing covers for the flush pipe connection and drain pipe connection does not create sufficient space for these connections, which would later allow for the direct connection of almost any toilet bowl to the wall without the need for complex and difficult additional work, such as deliberately prying open the wall.Furthermore, depending on the design of the cistern and toilet body, different types of wall connections are required, for example, an electrical connection to supply power to the toilet body, for example, to heat water for a shower facility, for an odor extractor, or a hairdryer, an electrical connection to supply power to an electric actuator plate, and / or a water connection provided in addition to the flush pipe, for example, for a shower facility. Furthermore, conventional installation modules do not offer any safety precautions to ensure that the respective wastewater drain connection of the toilet body and the flush water supply connection of the toilet body are connected in a fluid-tight manner to the flush pipe connection and the drain pipe connection, respectively, when a toilet body is subsequently connected, even when providing pre-walls with a considerable depth.In addition, during the typically long construction period during which the mounting module is installed in a room before the construction of the pre-wall is completed, modifications to the mounting module can easily be made by unauthorized personnel or information about the installation requirements of the mounting module can be lost until the installing plumbing specialist finally installs a toilet body on the front of the pre-wall, which can lead to further errors in the installation of the toilet body.

[0005] The present invention is therefore based on the object of providing an assembly module or a method for realizing a pre-wall in front of such an assembly module or a method for realizing a WC installation or a system with such an assembly module, which at least partially eliminates at least some of the problems and disadvantages of known assembly modules or methods or systems.

[0006] As a solution to the above-mentioned problem underlying the invention, the invention proposes an assembly module having the features according to claim 1.

[0007] The mounting module is suitable for mounting a cistern, in particular behind a pre-wall which is arranged on a front side of the mounting module extending along a vertical and along a transversal line. The mounting module comprises a module frame which extends with its module frame height along the vertical and with its module frame width along the transversal line. The mounting module further comprises a drain pipe and a cistern with a flush pipe, wherein in a construction-time position of the mounting module which defines a fixed arrangement of the components of the mounting module relative to one another, the cistern is fastened to the module frame and the flush pipe forms a flush pipe connection which is open at the front side of the mounting module, and the drain pipe is fastened to the module frame and forms a drain pipe connection which is open at the front side of the mounting module.The assembly module according to the invention can have further features which are explained above in connection with generic assembly modules or methods.

[0008] According to the invention, the assembly module has a two-part connection extension, which comprises a connection element and a closure element. Preferably, the connection element and the closure element are each elements manufactured separately from the module frame. Preferably, the connection element is manufactured from plastic, preferably as an injection-molded part. Preferably, the closure element is manufactured from plastic, paper or cardboard. In the construction position of the assembly module, the closure element of the connection extension is detachably fastened to the module frame and the connection element and closes the flush pipe connection and the drain pipe connection. The closure element has on its front side, iewith its projection, viewed from the front side in a direction perpendicular to the transverse and vertical, has a transverse and a vertical extension within which both the flush pipe connection and the drain pipe connection are arranged, wherein this front side with its corresponding transverse and vertical extension, within which both the flush pipe connection and the drain pipe connection are arranged, protrudes by at least 15 mm, in particular at least 30 mm, in particular between 15 mm and 100 mm, beyond the module frame, i.e. beyond the front side of the module frame. In this case, protrusion generally means a protrusion along a direction that is perpendicular to the vertical and the transverse. The closure element is preferably fastened directly to the connection element and in particular directly to the module frame.In one embodiment, the closure element is attached to the connection element indirectly via the module frame. In one embodiment, the connection element and / or the closure element is attached to the module frame indirectly via the drain pipe attached to the module frame and / or via the flush pipe attached to the module frame. For this purpose, the connection element preferably has a first connection element section, which is inserted externally around the flush pipe connection for attaching the connection element to the flush pipe, and / or a second connection element section, which is inserted externally around the drain pipe connection for attaching the connection element to the drain pipe.Alternatively or additionally, the closure element preferably has a first closure element section which is inserted into the flush pipe connection for fastening the closure element to the flush pipe, and / or a second closure element section which is inserted into the drain pipe connection for fastening the closure element to the drain pipe. The closure element is preferably fastened to the module frame exclusively indirectly via the flush pipe and / or the drain pipe. The connection element is preferably fastened to the module frame exclusively indirectly via the flush pipe and / or the drain pipe. In this case, a corresponding design of the closure element and module frame as well as the closure element and connection element is always provided such that the closure element, starting from the construction position, can be detached from both the module frame and the connection element and can thus be separated and removed from both.By closing the flush pipe connection and the drain pipe connection, the closure element ensures that a clear cross-section through which the drain pipe connection and the flush pipe connection are accessible from the front of the assembly module in the construction position is significantly smaller, in particular at least 50% smaller, in particular at least 80% smaller, in particular at least 95% smaller, than the respective clear cross-section of the flush pipe connection and the drain pipe connection, forming the flush pipe connection and the drain pipe connection in a plane spanned by the transverse and vertical lines. Particularly preferably, the closure element closes at least the drain pipe cross-section in an odor-tight manner.

[0009] Starting from the construction-time position, the closure element can be detached from the connection element and the module frame to create an operating position for the assembly module. The operating position of the assembly module defines an arrangement of these components that differs from the arrangement of the components of the assembly module defined in the construction-time position. However, starting from the construction-time position, in the operating position the cistern is unchangedly attached to the module frame and the flush pipe unchangedly forms a flush pipe connection that is open at the front of the assembly module and the drain pipe is unchangedly attached to the module frame and forms a drain pipe connection that is open at the front of the assembly module. Particularly preferably, a changed arrangement of the closure element relative to the other components of the assembly module is the only difference between the construction-time position and the operating position.In one embodiment, the only difference between the operating position and the construction-time position is a change in the position of the closure element and the connecting element relative to the other components of the assembly module. In the operating position, the connecting element is fastened to the module frame, preferably unchanged from the construction-time position. In the operating position, the connecting element protrudes with its front side beyond the module frame, i.e., beyond the front side of the module frame, in particular by at least 5 mm, in particular between 5 mm and 30 mm beyond the module frame, preferably unchanged from the construction-time position.The connecting element forms a guide running along a direction perpendicular to the transverse and perpendicular to the vertical, which guide runs with at least one guide section in front of the front side of the module frame and, in particular, extends further behind the module frame with a further guide section which is directly connected to the first-mentioned guide section.Particularly preferably, starting from the operating position, the closure element can be placed on the front side of the connection element in order to realize the construction-time position, in particular without changing the position and fixing of the connection element relative to the module frame, and can be releasably fixed relative to the connection element, for example by directly fixing it to the connection element and / or fixing it to the module frame, wherein particularly preferably the closure element with its front side, with which it has the said transverse and vertical extension, within which both the flush pipe connection and the drain pipe connection are arranged, protrudes in the construction-time position by at least 5 mm, in particular by at least 10 mm, beyond the front side of the connection element.

[0010] The assembly module according to the invention offers a number of advantages. By providing a two-part connecting extension, special consideration can be given to the different conditions and requirements during the construction period, during which the pre-wall is also being erected, and during the connection of a toilet to the assembly module after the construction period, i.e., after the pre-wall has been installed.By extending the closure element with its front side transversely and vertically over the flush pipe connection and the drain pipe connection in the construction position of the assembly module, thus covering both of these when viewed from the front, in particular by forming a flat, closed front side of the closure element, and closing the pipe connections, damage to these pipe connections can be prevented on the one hand and the ingress of contaminants into lines connected to these pipe connections can be prevented on the other.As the closure element, with its front side, which covers the drain pipe connection and the flush pipe connection as seen from the front, protrudes significantly beyond the module frame, in particular by at least 15 mm, in particular by at least 30 mm, in particular by at least 50 mm, in particular between 15 mm and 100 mm, in particular between 30 mm and 100 mm, the closure element also serves as a placeholder for an opening to be provided in the pre-wall when the pre-wall is installed on the front of the assembly module. This makes it particularly advantageous to provide a sufficiently large opening in the pre-wall, which allows a universal connection of almost any WC body with almost any functionality. As the closure element specifies clear dimensions for the opening in the pre-wall and thus also enables a tiler, for example, to specifically provide the opening in the size of the closure element, iethe transverse and vertical extension of the closure element with its front side, it can also be ensured that only one opening is created in the pre-wall, which is covered by almost any conventional toilet body after its installation on the front of the pre-wall. By also providing a connecting element which is detachably attached to the closure element in the construction position and which, in the operating position, provides a guide with a guide section in front of the front of the module frame, it is ensured, on the one hand, that the connecting element is reliably fixed to the module frame in the construction position and does not get lost, and, on the other hand, that in the operating position, in which a toilet body can preferably be connected to the assembly module, a guide is provided which simplifies the connection of the toilet body.The guide can, for example, comprise a fluid guide from at least one of the drain pipe connection and the flush pipe connection to the front of the module frame, whereby in the event of a faulty connection of a waste water connecting line leading to a toilet body at the drain pipe connection and / or a faulty connection of a flush water connecting line leading to a toilet body at the flush pipe connection, any leaking water is guided in front of the module frame so that it can be detected from the front of the pre-wall. The guide can, for example, also be a geometric guide, for example by providing a cavity orof guiding side walls that allow for the targeted positioning of a connecting device, such as a hygienic flush supply hose or an electrical supply line or an electrical control device or other connecting device that can be connected to a toilet body, or other components such as a offset set for the targeted vertical installation of a toilet body. By extending in front of the module frame with at least one guide section, the guide ensures sufficient guidance along the direction perpendicular to the transverse and vertical lines and / or allows for sufficient storage space and the provision of sufficient guide sections to facilitate a toilet connection.Particularly preferably, the guide, with its guide section extending in front of the module frame, is arranged exclusively within a vertically and transversely extending extension area, which is covered by the said front side of the closure element, which protrudes at least 15 mm from the module frame, in the construction-time position with its transverse and vertical extensions. Particularly preferably, the entire extension of the connection element in the operating position, with which the connection element extends in front of the module frame, is arranged exclusively within a vertically and transversely extending extension area, which is covered by the said front side of the closure element in the construction-time position with its transverse and vertical extensions. Particularly preferably, the connection element is reversibly detachable from the module frame starting from the operating position, i.e., can be detached from the module frame and then reattached.A corresponding, reversibly detachable fastening can be achieved, for example, by locking and / or clamping. The module frame particularly preferably has two vertically running support struts and a plurality of transversely running transverse struts connecting the support struts. The drain pipe connection is preferably arranged vertically between two of the transverse struts, wherein the drain pipe preferably overlaps with at least one, in particular both, of the transverse struts at its end forming the drain pipe connection in a direction that is perpendicular to the vertical and transverse directions. The drain pipe is preferably fastened to at least one of the two transverse struts with its end forming the drain pipe connection via a fastening device, such as a clamp. The transverse struts are particularly preferably spaced vertically from one another by at least 11 cm.Particularly preferably, starting from the operating position, the connecting element is detachable from the module frame, releasing a free space on both transverse sides of the drain pipe connection, previously covered by the connecting element as seen from the front, wherein the free space on each of the transverse sides of the end of the drain pipe forming the drain pipe connection extends in the transverse direction over at least 5 cm, in particular at least 10 cm, starting from the respective transverse end of the end of the drain pipe, in particular extends vertically continuously between the two transverse struts, in particular in the transverse direction continuously up to the support strut adjacent to the respective transverse end of the end of the drain pipe.By releasing this free space, the connection of the drain pipe of the assembly module to a building-side wastewater line is particularly simplified, since after dismantling the connection element from the module frame, the free space allows easy handling of the drain pipe, in particular also dismantling and / or moving of the drain pipe from the module frame, whereby the drain pipe can be easily inserted into a wastewater line connection of the building-side wastewater line or connected to it.

[0011] In one embodiment, the vertical and horizontal extension of the element at its front side, which protrudes at least 15 mm beyond the module frame and within which both the flush pipe connection and the drain pipe connection are arranged, is each delimited by an outer side of the closure element running around the flush pipe connection and the drain pipe connection. The outer side preferably runs continuously around the flush pipe connection and the drain pipe connection, in particular continuously around it. The outer side preferably runs, in particular continuously, from the aforementioned front side of the closure element to the front side of the connection element or to the front side of the module frame along a direction that is perpendicular to the vertical and the transverse, wherein it runs around the flush pipe connection and the drain pipe connection over its course in this direction.Preferably, the outer side of the closure element includes the same transverse and vertical extension throughout its extension in this direction, from the front side of the closure element to the front side of the connecting element or to the module frame, so that a section through the outer side has the same planar extension in every plane spanned by the transverse and vertical lines within this region. By providing such a circumferential outer side of the closure element, the closure element can serve as a particularly good orientation for providing an opening in the pre-wall, in particular during the application of a tiled covering to the pre-wall.Particularly preferably, the outer side has an extension of at least 15 cm, in particular at least 20 cm, between its opposite absolute transverse ends, and an extension of at least 20 cm, in particular at least 25 cm, between its opposite absolute vertical ends. Particularly preferably, the circumferential outer side of the closure element encloses a transverse and vertical area of ​​at least 300 cm², in particular at least 400 cm². As a result, a particularly advantageous, large opening in the pre-wall, which can still be closed by a standard toilet body, can be kept free by the closure element.

[0012] In one embodiment, the connection element in the operating position, and in particular also in the construction position, has a fluid guide from the flush pipe connection and / or the drain pipe connection to in front of the module frame for draining off leaking water escaping from the flush pipe connection and / or the drain pipe connection. The guide formed by the connection element thus comprises the fluid guide or is designed as the fluid guide. As explained above, this can particularly reliably ensure that leaking water escaping from the flush pipe connection and / or the drain pipe connection is guided through the fluid guide in front of the module frame, particularly preferably in front of the prefabricated wall, thus preventing undetected moisture from building up behind the prefabricated wall, which could, for example, lead to damage to the building, such as the formation of mold.In this case, the fluid guide preferably extends with a first guide section in front of the front side of the module frame and with a second guide section starting from the first guide section to behind the flush pipe connection or the drain pipe connection, wherein particularly preferably the fluid guide and in particular the said first and second fluid guide sections each have a first part which is assigned to the flush pipe connection and runs below the flush pipe connection but above the drain pipe connection, and a second part which is assigned to the drain pipe connection and runs below the drain pipe connection, so that leakage water which emerges from the pipe connection assigned to the respective part can be reliably drained away via the two parts.Particularly preferably, the connection element has a first pipe socket, with which it is fluid-conductingly connected to the flush pipe connection in the operating position, and a second pipe socket, with which it is fluid-conductingly connected to the drain pipe connection in the operating position. The first and second pipe sockets thus at least partially form the fluid guide of the connection element and each have a first section that extends in front of the module frame and a second section that runs from the first module frame to behind the respective connection. The provision of a pipe socket as part of the fluid guide has proven to be particularly advantageous for particularly reliably guiding leakage water away from the respective pipe connection to in front of the module frame. Particularly preferably, the first pipe socket is arranged outside the flush pipe connection and / or the second pipe socket is arranged outside the drain pipe connection.

[0013] In one embodiment, the closure element has a first and a second cylindrical closure section, wherein in the construction position the first cylindrical closure section closes the flush pipe connection and the second cylindrical closure section closes the drain pipe connection. In one embodiment, in the construction position the first cylindrical closure section is arranged within the first pipe socket formed by the connection element and is connected via this to the flush pipe connection, and the second cylindrical closure section is arranged within the second pipe socket formed by the connection element and is connected via this to the drain pipe connection. In one embodiment, in the construction position the first cylindrical closure section is arranged in the flush pipe connection and the second cylindrical closure section is arranged in the drain pipe connection.

[0014] In one embodiment, the connection element has a cavity which has a front side and which is open at its front side and, in the operating position, is accessible from the front side, in particular from the front side of the mounting module. The cavity has a transverse and a vertical extension, wherein the flush pipe connection and the drain pipe connection are arranged within the transverse and vertical extensions of the cavity. The cavity can preferably comprise at least one partial cavity which is provided within the transverse and vertical extensions of the cavity and which is defined by a respective partial cavity wall which delimits the partial cavity transversely and / or vertically and extends with its partial cavity wall height perpendicular to the transverse and vertical.The cavity has an extension in a direction perpendicular to the transverse and perpendicular to the vertical, which extension is preferably at least 5 mm, in particular at least 10 mm long. Accordingly, the cavity is suitable for accommodating elements necessary for connecting a toilet body, such as supply lines, connection devices such as control devices, operating devices, transformers or the like, other components, etc., since sufficient space is provided by the depth of the cavity, i.e. its extension in a direction perpendicular to the vertical and the transverse. In one embodiment, the connection element has a first and a second pipe socket which are enclosed by the cavity, wherein at least a section of the wall of the respective pipe socket represents a partial cavity wall and the clear cross section of the respective pipe socket represents a partial cavity.Generally, the cavity is preferably delimited by a wall, preferably by a transversely and vertically circumferential wall, wherein the wall extends with its wall height perpendicular to the transverse and perpendicular to the vertical and preferably defines the extent of the cavity in this direction via its wall height. Particularly preferably, the wall has a wall height averaged over its circumferential length of at least 5 mm, in particular at least 10 mm, wherein the wall, with its circumferential length, surrounds a transversely and vertically extending region and thereby encloses a surface running in the vertical and transverse directions, which is preferably at least 300 cm 2 , in particular at least 400 cm 2 .Particularly preferably, the wall runs on both transverse sides of the flush pipe connection and the drain pipe connection with a section each vertically between the flush pipe connection and the drain pipe connection and is spaced transversely from the flush pipe connection and the drain pipe connection by these sections, in particular by at least 3 cm in each case, in particular on at least one transverse side by at least 5 cm, in particular at least 8 cm, in particular on both transverse sides by at least 5 cm, in particular at least 8 cm in each case. The cavity is thus preferably delimited by a wall which has a wall section which is spaced transversely from the flush pipe connection and the drain pipe connection. As a result, the cavity can provide a particularly suitable receiving space for a connection device for the toilet body.In general, the cavity is preferably arranged with its entire transverse and vertical extent completely within a vertically and transversely extending extension region which the front side of the closure element covers with its transverse and vertical extent in the construction position, wherein this is the said front side of the closure element, which protrudes at least 15 mm beyond the module frame in the construction position. This ensures that the closure element provides a placeholder in the construction position and thus during construction, in particular during construction of the pre-wall, which ensures access to the cavity after the pre-wall has been realized. In general, the assembly module particularly preferably has a cavity cover which is designed to reversibly close at least part of the front side of the cavity starting from the operating position.For this purpose, the cavity cover particularly preferably has mechanical closure means that correspond to mechanical closure means provided on the cavity, in particular on the wall of the cavity or on at least one partial cavity wall. By providing a cavity cover that can reversibly close part of the front side of the cavity, in particular the front side of a partial cavity delimited by a partial cavity wall, particularly good chambering of a connecting device or other component used for a toilet, in particular an electronic component, can be ensured. This can particularly advantageously protect this component or the connecting device when a toilet body is connected to the mounting module, which typically remains unchanged over a very long period of many years.In general, the cavity preferably has a rear wall on its rear side opposite the front side, which is open in the operating position, which closes at least 50%, in particular more than 70%, of the rear side of the cavity. In any case, the rear wall does not close the clear cross-sections of the flush pipe connection and the drain pipe connection, which are preferably located within the cavity. By providing a rear wall that at least partially closes the rear side of the cavity, the cavity can ensure a particularly targeted accommodation of the connecting device or other components and, in particular, also better protection of the same.

[0015] In one embodiment, the connecting element and the closure element are configured to correspond to one another in such a way that, in the construction position, their transverse and vertical ends merge flush with one another, at least in sections. Particularly preferably, the connecting element does not protrude transversely or vertically beyond the closure element. This flush transition can particularly facilitate the use of the assembly module, and in particular, the construction of a pre-wall in front of the assembly module can be particularly simplified.

[0016] In one embodiment, the assembly module has a supply hose that runs from an electrical connection and / or a water connection of the cistern to the connection element and opens into a region of the connection element that lies within a vertically and transversely extending extension region that the front side of the closure element covers with its transverse and vertical extension in the construction-time position, wherein the front side protrudes at least 15 mm beyond the module frame. Preferably, the region into which the supply hose opens lies, at least in sections, transversely outside the flush pipe connection and the drain pipe connection. This allows for particularly good accessibility to this area, even after connecting a toilet body.Particularly preferably, the region extends transversely between 60 mm and 150 mm, in particular between 60 mm and 120 mm, beyond the vertical line running centrally through the flush pipe connection and the drain pipe connection. Particularly preferably, the supply hose opens into the cavity of the connecting element. Particularly preferably, the cavity has the aforementioned rear wall, wherein the rear wall has an opening into which the supply hose opens. Generally, the rear wall preferably has predetermined breaking sections that can be broken open from the front under pressure, thereby releasing an opening defined by the predetermined breaking sections.This allows an installer, for example an electrician or plumber, to provide an opening in the rear wall of the cavity at a location suitable for connecting the respective toilet body, through which a connection device to the toilet body can be led or through which a component extending away from the toilet body at its rear can protrude.

[0017] Generally, the cavity preferably comprises at least one partial cavity, in particular a plurality of partial cavities. Preferably, at least one, in particular a plurality of the partial cavities are arranged with their vertical and transverse extensions completely outside the vertical and transverse extensions of the flush pipe connection and the drain pipe connection. The partial cavity is provided within the cavity and is delimited at least in sections by a partial cavity wall from regions of the cavity that are provided horizontally and / or vertically adjacent to the partial cavity. In one embodiment, the cavity comprises a partial cavity that is enclosed circumferentially by a partial cavity wall, wherein preferably a portion of the partial cavity wall is provided by the wall of the cavity, whereas the remainder of the partial cavity wall extends within the cavity. Particularly preferably, a partial cavity wall is provided in the cavity,which delimits the two sub-cavities of the cavity arranged next to one another. Particularly preferably, the cavity has at least one sub-cavity which, with respect to the vertical and with respect to the transverse, lies outside the flush pipe connection and outside the drain pipe connection. In one embodiment, the connecting element has a first and second pipe socket as explained above, and the pipe socket wall of the first and second pipe socket each forms at least a portion of the sub-cavity wall. Particularly preferably, the supply hose explained above opens into one of the sub-cavities. Preferably, the rear wall of the cavity explained above extends at least partially, in particular completely, over the rear side of the sub-cavity, wherein the rear wall has an opening within the sub-cavity.into which the supply hose opens. This opening is particularly preferably located vertically below the flush pipe connection and vertically above the drain pipe connection, wherein this opening preferably has a first vertical distance from the flush pipe connection and a second vertical distance from the drain pipe connection, wherein the second distance is preferably at least twice, in particular at least three times, in particular at least five times the first distance. The opening is particularly preferably arranged in a transverse region which is transversely spaced less than 2 cm from a vertical axis which runs through the center of the flush pipe connection and through the center of the drain pipe connection. The transverse extent of the opening is particularly preferably limited to a transverse region which extends up to a maximum of 10 cm, in particular a maximum of 8 cm.in particular extends a maximum of 5 cm transversely from said vertical axis.

In the method according to the invention, a building panel is fastened to the front of the mounting frame of the assembly module and a tile covering is provided on the front of the building panel while the assembly module is in the construction position. In this case, a through-opening is provided in the building panel, the opening edge of which runs around the closure element, wherein in particular the opening edge rests against the closure element or is continuously spaced by less than 5 cm, in particular less than 2 cm. The closure element extends through the opening provided in the building panel and thus projects beyond the building panel at the front of the building panel.The tiling is arranged around the closure element, while the closure element extends through the opening in the building board and beyond the tiling, thus ultimately extending through the tiling to the front of the tiling. Thanks to the use of the mounting module according to the invention, the method according to the invention enables the simple and targeted realization of a pre-wall to which various toilet bodies can be mounted at a later date and connected to the mounting module.

[0022] The invention further relates to a method for realizing a WC installation with a WC body installed on the front of a pre-wall, wherein a mounting frame with a cistern fastened thereto is provided behind the pre-wall and a flush pipe connection of the cistern and a drain pipe connection are provided behind the pre-wall, wherein a connection extension fastened to the mounting frame, which conceals the flush pipe connection and the drain pipe connection transversely and vertically and is in particular connected to these pipe connections in a fluid-conducting manner, extends from the mounting frame through an opening provided in the pre-wall, in particular an uninterrupted opening.In the method according to the invention, in a first method step, a closure element of the connection extension forming a front side of the connection extension is removed from the module frame from the front side of the prefabricated wall, while in particular a connection element of the connection extension remains unchanged and attached to the module frame behind the prefabricated wall. Particularly preferably, the connection element is fluidically connected to the aforementioned pipe connections, i.e., the drain pipe connection and the flush pipe connection, before, during, and after the first method step, ensuring fluid guidance of leakage water emerging from the pipe connections in front of the module frame.In a second method step following the first, a connecting flush pipe is connected to the flush pipe connection and the toilet body, and a connecting drain pipe is connected to the drain pipe socket and the toilet body, while the connecting element is attached, preferably unchanged, to the module frame behind the pre-wall. Particularly preferably, the connecting element is fluid-conductingly connected to the aforementioned pipe connections, ensuring fluid guidance of any leakage water escaping at the transition between the respective pipe connection and the respective connecting pipe in front of the module frame, in particular in front of the pre-wall.Particularly preferably, in a third method step carried out after the first method step, which can be carried out, for example, before, during or after the second method step, a connection additionally provided on the assembly module, in particular a water connection for a hygiene flush and / or an electrical connection, for example for a hygiene flush or the actuating device of the cistern, is connected to the toilet body. The connection is arranged on the module frame in an area which, before the first method step is carried out, is arranged within, in particular exclusively within, the transverse and vertical extent of the closure element. Particularly preferably, the connection is concealed by the closure element before the first method step is carried out and is made accessible from the front of the pre-wall by dismantling the closure element during the first method step.

[0023] The invention further relates to a system for providing assembly information for an assembly module according to the invention and / or for a further sanitary article having a further QR code. The system according to the invention comprises the assembly module and / or the further sanitary article as well as an intermediate database and an information storage database. The at least one QR code, in particular one of the QR codes provided on the assembly module or the further QR code, contains as information a unique reference to reference information stored in the intermediate database. This reference information contains a unique reference to specific assembly information stored in the information storage database. In general, the invention also relates to a system for providing information about a sanitary article having a QR code provided on the sanitary article, also independently of the assembly module according to the invention.By providing an intermediate database and an information storage database, the QR code can contain dynamically changeable information that can be changed easily and can be very detailed without the QR code having to be made more complex. It should be noted that a complicated design of a QR code, which can contain a larger and therefore more complex amount of information, makes the QR code more susceptible to errors. The inventors have recognized that by creating a sanitary article, in particular an assembly module, with a QR code and providing an intermediate database and an information storage database in which the aforementioned reference information orInformation about the sanitary article is contained, a structure is created which enables a manufacturer of the sanitary article to store changeable, in particular correctable, information about the sanitary article in the information storage database at different times, while having control over the reference with which the QR code is linked to the corresponding information about the sanitary article via the intermediate database. Particularly preferably, the QR code contains at least two different pieces of information, each of the pieces of information containing a different reference to another piece of reference information stored in the intermediate database, which contains a unique reference to another piece of assembly information stored in the information storage database.Additionally or furthermore, the reference information stored in the intermediate database can have a multiple coding, which, depending on a coding parameter additionally transmitted with the transmission of the reference transmitted in the QR code, refers to assembly information stored in the information storage database and associated with the respective coding parameter. The assembly information is only one example of any other information relating to the sanitary article. In the second alternative, which can be provided in addition to or as an alternative to the first alternative, reference information with a multiple coding is stored in the intermediate database, to which the QR code clearly refers.When reading the QR code, a coding parameter can be transmitted depending on the software used to read the QR code or send the reference. This coding parameter selects the multiple coding. This allows the reference information to be linked to a specific piece of information in the information storage database based on the coding parameter transmitted by the software used to read and transmit the QR code. Both of these alternatives offer the particular advantage that, by providing a single QR code, different people can receive different information. For example, specialist personnel connected to the manufacturer of the mounting module can obtain information about the mounting module that is not accessible to an installer, such as the batch number, serial number, etc.In the event of maintenance, the relevant specialist personnel can therefore receive additional information about the assembly module if necessary.

The assembly module 1 further comprises an installation tunnel 4 for bridging a pre-wall thickness, which can be arranged around an actuating device plate 20 that closes an inspection opening of the cistern 2. The assembly module 1 further has a shell protection 40 that can be inserted into the installation tunnel 4 to protect the actuating device plate 20. The provision of an actuating device plate 20, an installation tunnel 4, and a shell protection 40 is generally advantageous according to the invention.The assembly module 1 further comprises a connecting element 6 that can be releasably attached to the module frame 100, as well as a closing element 7 that can be releasably attached to the module frame 100. In the present case, the closing element 7 can be attached to the module frame 100 via the connecting element 6 that can be attached to the module frame 100. The connecting element 6 has a first pipe socket 65 and a second pipe socket 68, which, in the construction position, are connected to the flush pipe connection 51 and the drain pipe connection 81, respectively. The closing element 7 has a first cylindrical closing section 75 and a second, not-shown, cylindrical closing section. In the construction position, the first cylindrical closing section 75 is arranged in the first pipe socket 65, and the second cylindrical closing section is arranged in the second pipe socket 68, for closing the flush pipe connection 51 and the drain pipe connection 81.The assembly module 1 further comprises two fastening rods 10 designed as threaded rods, as well as a storage cavity closure 710. The closure element 7 has a storage cavity 71 in which the fastening rods 10 are stored in the construction-time position, while their rod extension extends along the vertical Z. The storage cavity closure 710 can be releasably fastened to the closure element 7. The connection element 6 has a cavity enclosed by a transversely and vertically circumferential wall 60, which is open at its front side and partially closed at its rear side by a rear wall. The cavity comprises a first partial cavity 64 and a second partial cavity 63. The first partial cavity 64 is delimited from the second partial cavity 63 by a section of the partial cavity wall 61.Both partial cavities 63, 64 are each enclosed transversely and vertically circumferentially by a partial cavity wall 61, wherein the wall of the cavity forms a section of the respective partial cavity wall 61 and the pipe wall of the first pipe socket 65 forms a section of the partial cavity wall 61 surrounding the first partial cavity 64 and the second pipe socket forms a section of the partial cavity wall 61 surrounding the second partial cavity 63 and a further section, which the partial cavity walls of the first and second partial cavities 63, 64 jointly form, separates the partial cavities 63, 64 from one another. The supply hose 3 opens into the first partial cavity 64 at an opening 640. The second partial cavity is separated from the first partial cavity 64 by the partial cavity wall 61 and by a part enclosed by the assembly module 1, shown in . Figure 3cshown partial cavity cover 630 can be reversibly closed. The second partial cavity 63 is particularly well suited for accommodating an electronic component that can be connected to a toilet body to be connected to the mounting module 1 and / or the cistern 2. Through a feedthrough provided in the section of the partial cavity wall 61 separating the partial cavities 63, 64 from one another, an electrical line, via which a low voltage can be transmitted, can pass from the second partial cavity 63 and thus from an electronic device provided in the second partial cavity 63 into the first partial cavity 64 and from there via the opening 640 into the supply hose 3 and via this to the cistern 2.In addition, a further electrical line can reach the toilet body through a passage provided in this partial cavity wall 61 and / or in the partial cavity cover 630, for example to supply power to a hot water heater, a hairdryer and / or a communications module (e.g., a WLAN or Bluetooth module) that can be provided in the toilet body. By providing the cavity, in particular the aforementioned partial cavity 64, in particular the aforementioned second partial cavity 63, it can also be ensured, for example, that the cistern 2 does not have to be connected directly to a building-side power cable that has a correspondingly high voltage, but that the cistern can be connected indirectly via the electrical device arranged in the cavity, which can be particularly advantageous for safety reasons, especially with regard to the open water surface provided in the cistern. Figure 1Furthermore, a connecting sleeve 9 for connecting the drain pipe 8 to a sewage pipe of a building is shown as an example.

[0029] In Figure 2 comprehensively the Figures 2a and 2b For illustrative purposes, the assembly module 1 according to the invention is shown in Figure 1 shown in its construction position. For explanatory purposes, Figure 2a a view of the front of the assembly module 1. The front extends along the vertical Z and along the transverse X. In Figure 2b is a side view of the assembly module 1, wherein a view of the side is shown in the transverse direction, so that the side view extends along the vertical Z and along a direction Y, which extends perpendicular to the vertical Z and transverse X. From the synopsis of the Figures 2a and 2bIt is clear that the closure element 7 in the construction time position at its front side, which is in Figure 2a shown by the plan view from the front, has a transverse and vertical extension, within which the flush pipe connection 51 and the drain pipe connection 81 are arranged with their horizontal and transverse extension, said front, as shown in Figure 2b can be seen, protrudes beyond the module frame 100 and beyond the connecting element 6, whereby the protrusion naturally refers to the direction Y shown. Figure 2b It can also be seen that the supply hose 3 is connected to a connection of the cistern 2, so that the supply hose 3 enables a connection of the cistern connection to the first partial cavity 64.

[0030] In Figure 3 comprehensively the Figures 3a , 3b , 3c and 3d is the one in the Figures 1 and 2shown embodiment of an assembly module according to the invention in different positions. Figure 3a shows the assembly module 1 in a position in which the cistern 2, the supply hose 3, the flush pipe 5 and the drain pipe 8 are attached to the module frame 100. In this Figure 3a In the position shown, neither the connecting element 6 nor the closing element 7 are attached to the module frame 100. Figure 3a It can be seen that the supply hose 3 has a supply hose opening 31 which opens into the first partial cavity 64 when the connecting element 6 is attached to the module frame 100. Furthermore, Figure 3aIt can be seen that on both transverse sides of the drain pipe end forming the drain pipe connection 81, a transverse free space is provided, extending vertically between the two transverse struts 101, between which the drain pipe connection 81 is provided. This allows the drain pipe 8 to be handled particularly easily in order to be connected to a building-side connection of a sewer line. Figure 3b shows the assembly module 1 in its operating position. In this operating position, the connecting element 6 is attached to the module frame 100, and the cavity, including the partial cavity 63, of the connecting element 6 is accessible from the front of the assembly module 1. In the operating position, the first pipe socket 65 and the second pipe socket 68 are already connected to the flush pipe connection 51 and the drain pipe connection 81, respectively. Figure 3ca position of the assembly module 1 is shown which has been changed from the operating position, in which the partial cavity 63 is reversibly closed by the partial cavity cover 630. In Figure 3d the construction time position of the assembly module 1 is shown, in which the installation tunnel 4 and the shell protection 40 as well as the closure element 7 are attached to the module frame 100, wherein the Figure 1 shown fastening rods 10 are arranged in the storage cavity 71 of the closure element 7 and the storage cavity 71 is reversibly closed by the storage cavity closure 710.
