Description

Connection element for a liquid-carrying supply line for mounting on a

Building structure and / or a support structure for building services installations

The invention relates to a connection element for a liquid-carrying supply line for mounting on a building structure and/or a support structure for building services installations, comprising a coupling element with an inlet for connection to the supply line and an outlet and for dispensing a liquid from the

Supply line.

Liquid-carrying supply lines are widespread in the field of building technology. These include, for example, hot water pipes and cold water pipes, which are usually connected to fittings such as faucets, showers and the like

are.

One of the challenges of modern building technology is to shield the interior of the building from noises caused by the liquid flowing in these supply lines. Furthermore, it is essential that there are no leaks or leaks in the area of the transition between the supply lines and the fittings connected to them. In drywall, in particular, such leaks can allow liquid to enter cavities in drywall and cause costly consequential damage. These include, for example, swelling of the walls or mold growth. In addition, it is particularly helpful for hot water pipes

to limit heat loss through the ducts.

Coupling elements are known in the prior art which ensure a connection between a supply line and a fitting to be connected to it. These are usually made of metal to ensure pressure resistance against a liquid pressure prevailing in the supply line and are fixed in or on a wall. Furthermore, installation sleeves are known, which are slipped over an outlet of the coupling element so that any liquid escaping from the outlet, for example in the event of a leak, is collected by the installation sleeve. Thus, this liquid does not penetrate into the building structure, and cannot adhere to it

cause consequential damage.

Although coupling elements and installation sleeves according to the prior art offer a certain degree of protection against leaks, the protective function of the installation sleeve can, for example, be lost in the case of a slightly tilted installation between the coupling element and installation sleeve

be affected. In addition, these prior art solutions offer only one

very limited noise damping between the coupling element and the

Building structure, like a wall, and also no thermal insulation.

The object of the present invention is therefore to provide a way of connecting liquid-carrying supply lines which provides noise decoupling of the building structure and improved protection against leaks

while providing easy installation. This object is achieved by a connection element with the features of claim 1.

The connection element according to the invention for a liquid-carrying supply line is suitable for mounting on a building structure, such as on a wall, in particular a drywall. Furthermore, the connection element according to the invention is suitable for mounting on a holding structure for technical building installations. This includes, for example, substructures in the form of installation boxes for bathroom fittings, toilet fittings or the like. The connection element comprises a coupling element with an inlet for connection to the supply line and an outlet and for dispensing a liquid from the supply line. The connecting element comprises a sleeve that at least partially surrounds the coupling element, and a damping element. The damping element is arranged between the coupling element and the shell, and supports the coupling element in the shell, and in a state of the connection element fastened to the building structure, at a distance from the building structure. The inlet and outlet are at a substantially right angle

arranged to each other.

The configuration according to the invention of the connection element with the damping element, which supports the coupling element in the casing, provides the advantage that the coupling element is decoupled from the damping element from the casing. This effectively prevents noise and vibrations from being transmitted from the coupling element to the shell and thus subsequently to the building structure. Furthermore, the coupling element is stored spaced apart from the building structure by the damping element, whereby heat transfer from the coupling element to the

Building structure is reduced.

According to the invention, the coupling element between the outlet and the inlet is completely surrounded by the damping element at least along a section of the coupling element, wherein the damping element along the section

Completely fills the space between the coupling element and the shell. This will

achieves the advantage that noise emanating from the coupling element along the section is damped in all spatial directions by the damping element. In addition, through the damping element thereby at the same time a seal against any

Leaking liquid and / or condensation provided.

The damping element is preferably made from a flexible foam. This achieves the advantage that the connection element can be produced in a simple manner. In addition, flexible foam provides good noise insulation, thermal insulation, vibration insulation and liquid tightness.

According to the invention, the sleeve comprises a receiving body, in which the coupling element is received, and an installation sleeve. The mounting sleeve is removably attached to the receiving body and the outlet of the coupling member extends from the receiving body into the mounting sleeve. This achieves the advantage that any liquid escaping at the outlet is caught by the installation sleeve and thus does not flow into the building structure. Due to the removable attachment, the installation sleeve can be subsequently attached to the receiving body without the installation sleeve after the connection element has been installed. This simplifies the installation of the connection element. The inlet of the coupling element also preferably exits the shell. This simplifies the connection of the connection element to the supply line. According to the preferred embodiment of the connection element according to the invention, the installation sleeve is connected to the receiving body by means of a bayonet lock. Of the

Bayonet locking provides a simple, secure and quick connection.

The sleeve preferably has at least one receptacle for receiving the coupling element in the sleeve. This changes the alignment of the coupling element

in the envelope during production.

The shell also preferably has at least one fastening element for fastening the connection element to the building structure and/or the holding structure for building services installations. As a result, the connecting element in a simple manner, for example

be attached to a wall or the support structure by means of a screw connection.

According to the preferred embodiment variant of the connection element according to the invention, the installation sleeve has a first cross section at a first end facing the outlet of the coupling element, and a second cross section at a second end facing away from the first end, the second cross section being larger than the first cross section. and the damping element has a distance between the first cross-section and the

Outlet of the coupling element fills. This is a stage in the course of

Mounting sleeve provided, preventing eventual at the outlet

escaping liquid flows through the installation sleeve into the building structure and may cause damage there. At the same time, the damping element provides a seal

between the installation sleeve and the connecting element.

In the region of the distance between the first cross section and the outlet of the coupling element, the damping element preferably has a diameter that tapers in the direction of the second end. As a result, the seal between the

Damping element and the installation sleeve improved.

According to an alternative embodiment variant of the connection element according to the invention, the installation sleeve has a first cross section at a first end facing the outlet of the coupling element, and a second cross section at a second end facing away from the first end, the first cross section essentially corresponding to an outlet cross section of the coupling element , and the second cross section is larger than the first cross section. This achieves the advantage that the seal between the coupling element and the connecting element is provided, for example, by means of a press fit or a separate seal that can be arranged between the coupling element and the installation sleeve. The seal can also be integrated in the installation sleeve. The seal offers the advantage that it can be easily removed in the event of a leak

is interchangeable.

The connection element according to the invention, as well as preferred and alternative

Design variants are explained in more detail below with reference to the figures.

FIG. 3a shows the connection element according to FIG. 2c with a damping element. Figure 3b shows the connection element in the representation of Figure 2b with the

damping element.

The connection element 1 according to the invention for a liquid-carrying supply line, not shown in the figures, is shown in FIG

Exploded views visible from different perspectives. The inventive

Connection element 1 is suitable for mounting on a building structure, such as drywall, which is also not visible in the figures, and comprises a coupling element 2 with an inlet 3 for connection to the supply line, and an outlet 4 for dispensing a liquid from the supply line . Furthermore, the connection element 1 according to the invention is suitable for mounting on a holding structure, not shown in the figures, for technical building installations. This includes, for example, line-guiding substructures in the form of installation boxes for bathroom fittings, toilet fittings or the like, which in turn is connected to the building structure. Further support structures for building services installations result from this exemplary reference for the person skilled in the art. The connection element 1 is preferably made of a pressure-resistant material, such as a metal. Other suitable materials are well known to those skilled in the art. The connecting element 1 according to the invention comprises a sleeve 5 at least partially surrounding the coupling element 2 and a damping element 6. The damping element 6 is not shown in FIGS. 1a to 2c for a better overview, and can be seen in FIGS. 3a and 3b. As shown in FIG. 3a and FIG. 3b, the damping element 6 is arranged between the coupling element 2 and the sleeve 5, the coupling element 2 being mounted in the sleeve 5. FIG. The damping element 6 is shown in FIG. 3b with a black area. When the connecting element 1 is attached to the building structure, not shown in the figures, the damping element 6 also supports the connecting element 2 in the shell 5 at a distance from the building structure is formed. This configuration of the coupling element 2 and the damping element 6 in the shell 5 of the connection element 1 according to the invention prevents a direct transmission of sound from the connection element 1 to the building structure. In addition, vibrations are also damped by the damping element 6 and direct contact of the coupling element 2 with the building structure is avoided. This causes a thermal

Insulation of the coupling element 2 achieved by the building structure.

According to the invention, as can be seen in FIG. 3b, the connection element 1 is completely surrounded by the damping element 6 between the outlet 4 and the inlet 3, at least along a section A of the coupling element 2, which can be seen in FIG. 3b. The damping element 6 completely fills a space between the coupling element 2 and the casing 5 along the section A. As a result, the damping element 6 completely seals a space between the sleeve 5 and the coupling element 2 , which prevents liquid escaping from the outlet 4 from entering the connecting element 1 between the sleeve 5 and the coupling element 2 . The damping element 6 is preferably made of a flexible foam. This can in

During the production of the invention

Connection element 1 are simply injected into the shell 5, whereby the production

is simplified.

The shell 5 is designed in a multi-part construction. As can be seen in FIG. This can be seen in FIGS. 2a and 2b, in which the connection element 1 according to the invention is shown in the assembled state. FIG. 2b shows a sectional representation of FIG. 2a, with the damping element 6 being omitted in these figures for a better overview. The installation sleeve 8 is removably fastened to the receiving body 7, as can be seen in FIG. 1a and FIG. 1b. The outlet 4 of the coupling element 2 extends in the assembled state according to Figure 2a and Figure 2b preferably from the receiving body 7 into the installation sleeve 8. This has the advantage that any liquid escaping from the outlet 4, for example in the event of a leak at the outlet 4 between the outlet 4 and a fitting, not shown, which is connected to it and is collected by the installation sleeve 8 . Thus, this liquid can not enter the receiving body 7, which is usually installed within a drywall. This prevents the liquid from getting into the drywall and causing damage there. In addition, in the preferred embodiment variant of the connecting element 1 according to the invention, the inlet 3 of the coupling element 2 emerges from the casing 5, preferably from the receiving body 7. This is also shown in Figure 2a and Figure 2b. This simplifies the connection of the inlet 3 to the liquid-carrying supply line. The multi-part construction of the shell 5 also has the advantage that the installation sleeve 8 can be removed from the receiving body 7 during installation of the connection element 1 in or on a building structure or a holding structure for building services installations, or only at the end of the installation on this can be set up. This makes it easier to connect the inlet 3 to a supply line by means of a press connection, for example. Pressing tools must be used to create a press connection. In order to prevent the pressing tool from coming into contact with the installation sleeve 8 during installation, this can only be connected to the receiving body 7 after the press connection has been established.

As can be seen in the figures, the installation sleeve 8 has a plurality of grooves 15 . These grooves 15 indicate possible cutting paths for shortening the mounting sleeve 8 to the

Installation sleeve 8 flat with a surface of a wall in which the inventive

Connection element 1 is installed to be able to cut off. As a result, the installation sleeve protrudes

8 does not protrude from the wall. In addition, the mounting sleeve 8 of the invention

Connecting element 1 can be introduced into a sealing sleeve, which is not visible in the figures and is well known to those skilled in the field of building technology, and which is installed in the wall. This allows the installation sleeve 8 to be carried out by a

Wall sealed against liquid ingress.

The installation sleeve 8 is preferably connected to the receiving body 7 by means of a bayonet lock 9 . The bayonet catch 9 can be seen in FIG. 1b. This achieves a secure connection of the installation sleeve 8 to the receiving body 7, the installation sleeve 8 being able to be connected to the receiving body 7, for example after the installation of the receiving body 7 with the connection element 2 arranged therein, for example in a drywall. This will make the

Installation of the connecting element 1 much easier.

As can be seen in FIG. 2c, the sleeve 5 preferably has at least one receptacle 10 for receiving the coupling element 2 in the sleeve 5 or in the receiving body 7 of the sleeve 5. For this purpose, in the preferred embodiment variant of the connecting element 1 according to the invention, two bolt-like rods or guides are formed in the receiving body 7, onto which corresponding holes or recesses of the coupling element 2 can be pushed. As a result, the coupling element 2 is connected to the receiving body 7 or the sleeve 5 and fixed in it before the receiving body 7 is filled with flexible foam or another material suitable as a damping element 6 in order to form the damping element 6 . After the receiving body 7 has been foamed with flexible foam, the connecting element 1 is in the configuration shown in Figures 3a and 3b, with the receptacle 10 together with the coupling element received thereon being supported by the flexible foam or the damping element 6, at least in the area of the

Shot 10 has been completely enclosed.

In order to achieve a simple attachment of the connection element 1 to the building structure and/or the holding structure for building services installations, for example on or partially within a drywall, the cover 5 preferably has at least one attachment element 11 . In the preferred embodiment shown in the figures, a plurality of holes are provided in the receiving body 7, which

Implementation serve for example of screws or nails.

As can be seen from FIG. 2b and FIG. 3b, the installation sleeve 8 according to the preferred embodiment variant of the connection element 1 according to the invention has a first cross section Q1 at a first end 12 facing the outlet of the coupling element 2

a second end 13 facing away from the first end 12 has a second cross section Q2.

The second cross section Q1 is larger than the first cross section Q1, and the damping element 6 fills out a distance 14 between the first cross section Q1 and the outlet 4 of the coupling element 2, as can be seen in FIG. This provides a step in the course of the installation sleeve 8, which prevents any liquid escaping at the outlet 4 from flowing out via the installation sleeve 8 into the building structure and possibly causing damage there. At the same time, the damping element 6 provides a seal between the installation sleeve 8 and the receiving body 7 . The consequence of this is that no separate seal is required between the installation sleeve 8 and the receiving body 7 or the coupling element 2 . This considerably simplifies the installation of the connecting element 1 since a separate seal can be lost or damaged during installation. As can be seen in FIG. 3b, the damping element 6 preferably has a diameter that tapers in the direction of the second end 13 in the region of the distance 14 between the first cross section Q1 and the outlet 4 of the coupling element 2 . In the region of the distance 14 between the first cross section Qi and the outlet 4 of the coupling element 2, the damping element 6 is thus designed in the shape of a truncated cone. As a result, the sealing effect between the damping element 6 and the installation sleeve 8 is improved. The frustoconical design or the shape of the damping element 6 in the area of the distance 14 between the first cross section Qi and the outlet 4 of the coupling element 2 with the increasing diameter is achieved in the course of the production of the connection element 2 according to the invention by an attachment element that cannot be seen in the figures , which is applied to the receiving body 7 in the area of the outlet 4 of the coupling element 2 . The attachment element has a negative image of the truncated cone shape of the damping element 6 . A space in the receiving body 7 between the receiving body 7, the coupling element 2 and the attachment element is then filled with flexible foam in order to form the damping element 6 . The top element is then removed again. The top element is preferably made of aluminum

manufactured.

By attaching the installation sleeve 8 by means of the bayonet lock 9, a pressure load is also applied to the damping element 6 in the region of the distance 14. This further improves the sealing effect of the damping element 6 . This also ensures that leaks flow away in the direction of the second end 13 . Liquid emerging from the outlet 4 is thus conducted through the installation sleeve 8 in the direction of the second end 13 and emerges from the installation sleeve 8 at the second end 13 . This prevents water damage to the building structure.

According to an alternative embodiment variant of the connecting element 1 according to the invention that is not visible in the figures, the installation sleeve 8 has at one point, the outlet 4

of the coupling element 2 facing, first end 12 has a first cross section Q1, and

a second end 13 facing away from the first end 12 has a second cross section Q>, the first cross section Qı essentially corresponding to an outlet cross section of the coupling element 2, and the second cross section Q1 being larger than the first cross section Q11. This achieves the advantage that the seal between the installation sleeve 8 and the connecting element 7 is provided, for example, by means of a press fit or a separate seal that can be arranged between the coupling element 2 and the installation sleeve 8 . The separate seal offers the advantage that this at a

occurring leakage is easily replaceable.
