• the connecting pieces which protrude from the assembly module according to the invention at both ends of each line section, are preferably designed as screw connections. Due to its inherent stability, the assembly module according to the invention withstands the torques exerted on it when it is connected to the sanitary installation without any change in the position of the parts foamed in it. Screw connections also offer the possibility of simply assembling assembly modules according to the invention for all common applications in advance.
• each shut-off valve and each meter lower part of an assembly module according to the invention is freely accessible through appropriate, preferably round recesses in the foam, so that the handle pieces of the shut-off valves and / or the water meter upper parts can be quickly and easily added without preparatory work - apart from removal of the protective caps - would be required.
• a vial which is visible at least from the front of the assembly component is embedded in the foam. If this dragonfly is provided on the upper, front edge of the foam, it can be viewed both from the front and from above. So that the assembly module according to the invention can be tiled optically, the center points of the shut-off fittings and the lower parts of the meter are arranged in a certain grid dimension, for example in a grid dimension of 153 mm, based on the plan view.
• This last-mentioned grid dimension corresponds to the grid dimension customary when using tiles with an edge length of 15 cm and allows exactly one 15 cm square tile to be placed between the four corner points, which result from two shut-off fittings and two counter bases. It goes without saying that assembly modules according to the invention can also be easily produced for other grid dimensions.

It can also protrude all existing mounting tabs from the surface in the manner described.
• the protruding fastening tabs of such modified embodiments are easier to grasp and fold or bend into their fastening position. Furthermore, they offer manufacturing advantages, which will be discussed below in connection with the manufacturing method according to the invention.
• Assembly modules according to the invention are preferably produced by the following method: First, the two line sections, for example (depending on the application, there may also be several line sections or only one), are tightly connected to the desired fittings, mainly here described case with a shut-off valve and a water meter lower part. If connecting pieces are not already attached to the fittings or meter lower parts, each end of the line sections is tightly connected to a connecting piece which has a length such that it protrudes from the finished assembly module.
• the line sections prepared in this way, which are connected to the desired fittings, are then placed in a cuboidal foaming mold, to which brackets belong, which ensure a parallel and a desired, spatially precisely defined arrangement of the line sections.
• the holding elements with the fastening tabs attached to them are next inserted into the foaming mold.
• the foaming mold can then be closed. Shaped pieces, which can be part of the foaming mold and protrude into the foaming cavity, prevent the upper sides of the shut-off fittings and the counter parts from being foamed later.

• each holding element can be fixed in the foaming mold by means of these two fastening lugs, in that the fastening lugs arranged on opposite ends of the holding element engage in corresponding recesses in the inner wall of the foaming mold, the depth of which depends on the material thickness Fastening tabs corresponds at least approximately.
• the holding elements are arranged in a defined manner in the foaming mold and their position can no longer be changed even by the introduced foam.
• a further advantage of such an embodiment or of a manufacturing method designed in this way is that the fastening tabs protruding somewhat from the foaming surface can be gripped more easily in order to be able to be folded or bent into their fastening position.
• the foam used is preferably a two-component PU foam.
• the foamed assembly component can be removed from the foaming mold after about 15 to 20 minutes; the time to complete curing of the foam is about 30 to 40 minutes.

• the boundary lines of the cuboidal encapsulation 12 are indicated by dashed lines in FIG. 1, and the foam is shown in a transparent manner to make it easier to see the interior of the assembly module 10. However, it is understood that the foam used is in reality not transparent.
• each line section 14, 16 runs parallel to the rear of the assembly module 10 and has a shut-off valve 18 and a counter bottom part 20 which are tightly connected to the associated line section 14 or 16.
• the shut-off valves 18 as well as the lower parts 20 of the meter are located inside the foam casing 12.
• the ends of each line section 14, 16 are formed by connecting pieces 22, which are also sealed with a shut-off valve 18 or a meter base 20 are connected and protrude outward from the foam 12.
• the connecting pieces 22 are each provided with an internal thread 24 and thus designed as screw connections.
• the connection between the shut-off valve 18 or the counter lower part 20 and the associated line section 14 or 16 is also designed as a screw connection.
• shut-off valves 18 and the counter lower parts 20 are arranged in the encapsulation 12 in such a way that they can be completed from the front of the assembly module 10, i.e. that a handle can be placed on each shut-off valve 18 and an upper counter part on each lower part 20.
• the center points of the shut-off valves 18 and the counter lower parts 20 are arranged in such a way that a grid dimension A results, which in the example shown has a value of 153 mm. In this way, exactly one tile with an edge length of 15 cm can later be placed on the surface of the assembly module 10 delimited by the four center points. For other tile sizes, the grid dimension A naturally has a different value.
• a holding element 26 is arranged in the casing 12 and held by it, which has fastening lugs 28 and 30 for fastening the assembly module 10 at the place of use. So that the holding elements 26 are sufficient are stably anchored in the encapsulation 12, their band-shaped base body 26 ', from which the fastening tabs 28 and 30 extend, is located a few centimeters from the associated side surface of the assembly module 10 within the encapsulation 12. As can be seen from the figures is, the fastening tabs 28 and 30 are arranged flush with the surface of the foam 12 and can be brought out of this position by folding out 90 ° into a fastening position. If the holding element 26 is a sheet metal strip, as in the example shown, the fastening tabs 28, 30 are folded out by simply bending them out.
• Each holding element 26 has two fastening lugs 28 and two fastening lugs 30, of which the fastening lugs 28 are intended for fastening the assembly module 10 to a wall arranged behind it, while the fastening lugs 30 for fastening the assembly module 10 to the side Wall sections, in particular, however, are intended for fastening to a stud wall construction, as is used in pre-wall installation systems.
• the distance between the two fastening tabs 30 of a holding element 26 or the spacing of the holes present in the fastening tabs is then expediently chosen so that this spacing corresponds to the grid dimension of the pre-wall installation system. If the assembly module 10 is installed under plaster, usually only the fastening tabs 28 are used, whereas in the case of a pre-wall installation normally only the fastening tabs 30 are used.
• the material from which the foam 12 is made is, in the exemplary embodiment shown, a moisture-repellent two-component PU foam which, when cured, has a density between 90 kg / m 3 and 120 kg / m3.
• a foam with such a density guarantees an extremely stable cohesion of the entire assembly module 10 and in particular can easily cope with the stresses that occur when the assembly module 10 is connected to a sanitary installation.
• a lamp 32 is embedded in the foam at the front at the upper edge of the foam casing 12, so that a separate spirit level is no longer required.
• the exposed surface of the encapsulation 12 which can be smooth or slightly rough, represents an excellent substrate for tiling.
• FIG. 2 shows a second exemplary embodiment of an assembly component 10, which differs from the first exemplary embodiment described above in that only one line section 14 and, accordingly, only one shut-off valve 18 and one counter part 20 are present. Otherwise, the second embodiment corresponds to the first. Assembly modules according to the second exemplary embodiment are used, for example, where only detection of the hot water consumption is necessary.
• FIG. 2 also shows two protective caps 34, 34 'which are inserted into the cutouts 25, 25' in order to protect the shut-off fitting or meter fitting, which has not yet been completed, on the transport path.
• the encapsulation 12 advantageously has one or more channels 36 (see FIG. 1), which extend from the outer surface of the encapsulation 12 to the meter bases 20 extend. Electrical cables can be passed through these channels, which, if necessary, enable the meters to be read remotely if the meters are equipped with a pulse generator.
• the channels 36 can already be created during the foaming process by means of corresponding shaped pieces, but they can also be subsequently drilled or punched out easily.
