Description

The invention relates to a method for providing a closed water supply of a cylinder-shaped connection piece of a concealed pipe of a water pipe, which is arranged on a concealed side of a wall panel, through the wall paneling through to a room side of the wall panel, wherein in preparation for a construction of the wall panel of the connecting piece of the concealed pipe is sealed watertight with a construction stopper. The invention further relates to a mounting set for facilitating the implementation of the method according to the invention, which comprises a construction plug for connection to the connecting piece for blocking the connecting piece.

The present invention addresses the well-known problem of ensuring a closed flow of water from a spigot of a concealed pipe through a wall cladding to the room side of the wall cladding. Such a water guide through a wall covering is very often required in bathrooms or shower rooms or other premises with water connections, such as kitchens, since mostly water pipes are used with concealed pipes that should not be visible from a room after completion of the installation space and the other of to be contacted from the room for connecting sanitary Facilities such as faucets for taps or showers. The wall cladding separates the flush pipe from the room, so that the concealed pipe and the connecting piece of the concealed pipe are not visible from the room. A water supply from the concealed side of a wall cladding to the room side of the wall paneling is highly relevant for the protection of the building from moisture for various reasons. On the one hand must be ensured by the water guide a leak-free management of water from the connection piece of the concealed pipe to the room side of the wall panel so that on the room side a sanitary device, such as a faucet, can be connected and it does not lead to leakage on the concealed side Wall cladding comes, which can not be recognized from the room side and thus remain unrecognized for a long time and can cause corresponding damage to the building. On the other hand, such a water guide should be adapted to provide a continuous from the connection piece to the room side of the wall panel guide, which is adapted to be waterproof connected to the room side of the wall paneling. Because of course, the wall paneling must have a passage through which the water passage passes, and in the case in which the guide is not sealed against the room side of the wall panel, there is a risk that water from the room side between wall paneling and water flow through the Passing through to the concealed side of the wall cladding can and sustained damage to the building sets there. In addition, in the realization of such a water guide through a wall cladding throughout the construction process must be considered, with which the installation of a room is realized. Initially, the installer in the shell construction phase laid the flush pipes of the water pipe. Subsequently, by a tiler or similarly qualified Craftsman realized the wall paneling, which must then provide the implementation in the wall paneling for the water supply and should ensure a seal of the water supply and the guidance provided by them through the wall paneling to the room side of the wall paneling. It should also be noted that the installer of a concealed pipe must seal the connection piece of the concealed pipe watertight after installation, so that pressure and tightness tests can be made to the water line. This closure of the connecting piece is usually solved only after completion of the wall panel during the performance of the fine installation of the connection piece, after which a fitting is connected by means of a fitting fitting to the connection piece. This fine installation is usually carried out by another, independent of the above-mentioned craftsmen craftsman, who then has to resort to the preparation of the two aforementioned craftsmen and through the implementation in the wall paneling must make the connection of the fitting fitting to the connecting piece of the concealed pipe.

Various approaches are known in the art to address the problems described. In this case, the objective is to solve the problems described so that ultimately with the respective method, a room installation can be achieved, in which the room side of the wall paneling, ie comprising the implementation, through which the water supply passes, is sealed so that a dense overall system that meets the requirements of the European guideline ETAG022. In an approach known in the prior art of the plumber of the water pipe, the connecting piece of the concealed pipe after installation of the concealed pipe with a Construction plug sealed watertight. Such a construction stopper is for example from the document DE 10 2007 053 176 A1 known. In such a known method, the connecting piece of the concealed pipe has an internal thread into which the construction plug is screwed, wherein the construction plug has a flange, with which it presses a sealing ring against the connecting piece. In the subsequent steps described above, the wall cladding is first realized by a further craftsman with a passage around the Baustopfen and then mounted a sealing sleeve on the Baustopfen, as for example in the document DE 10 2010 018 677 A1 is described. This sealing sleeve is sealingly attached to the construction plug and is then integrated into a waterproof coating of the room side of the wall panel, so that the construction plug is sealed against the room side of the wall paneling. In a subsequent step is achieved in the fine installation of the construction plugs of the connection piece, after which then a fitting connection piece is screwed through the passage and through the sealing sleeve into the connection piece and is thereby sealingly secured to the connection piece. The sealing collar is then sealingly against the fitting fitting and seals the fitting fitting against the room side of the wall panel, wherein the fitting fitting provides the continuous guide from the connection piece to the room side and thus through the wall panel. However, this described method has various disadvantages. On the one hand there is the danger that when connecting the fitting fitting to the connecting piece no sufficiently good seal between the connecting piece and fitting fitting is made, so that there may be a leak on the concealed side of the wall panel, which may remain undetected from the room side. On the other hand arises in the Dismantling the Baustopfens high friction between Baustopfen and on the construction stopper sealingly fitting sealing sleeve, whereby the sealing sleeve can be damaged, which can subsequently affect the sealing of the sealing sleeve relative to the fitting fitting. In particular, this contributes to the fact that usually the fitting fitting has a smaller diameter than the construction plug. Since the sealing sleeve is usually extended to the size of the construction plug over a long time in the shell construction phase, it often contracts insufficiently after the removal of the construction plug and thus lies inadequately against the fitting fitting. Again, this can lead to a corresponding leak between valve fitting and sealing sleeve, which in turn can favor the ingress of water from the room side through the implementation of the concealed side of the wall paneling.

Further, in the prior art, a method is known, with which the disadvantages of the first-mentioned method to be addressed. In this method, connecting pieces are used on concealed pipes, which have such a length that they can protrude through a wall cladding, so that a craftsman who realizes the wall cladding, a sealing sleeve can be connected directly to the spigot, so that the spigot itself providing continuous guidance. As a result, the described leaks, which may occur in the former method, can be effectively avoided. However, this method also brings significant disadvantages. On the one hand, there is a considerable risk that the connection piece still projects beyond the wall cladding on the wall cladding after realization on the wall cladding, which is visually unattractive. The installer installing the concealed pipe with the connecting piece must therefore receive precise instructions from the tradesman following him, who realizes the wall cladding so that the installer of the concealed pipe can tailor the length of the connection piece to the intended wall cladding. However, such a detailed agreement is unrealistic in practice. In addition, a craftsman who realizes the wall paneling, do not use a standardized sealing sleeve, since such a sealing sleeve is adapted to the diameter of conventional construction plugs and conventional fitting fittings. Rather, such a craftsman would have received from the installer of the concealed pipe a sealing sleeve, which is tailored to the pipe system of the pipe manufacturer, which uses the installer of the concealed pipe to realize the water pipe. Even such a vote is unrealistic in practice and associated with a lot of effort.

The present invention has for its object to provide a method for providing a closed water flow from a connection piece of a concealed pipe through a wall panel, which at least partially solves at least one of the above problems. The invention is further based on the object of providing a mounting set with which at least one of the above-described problems of generic methods and systems used therefor can be at least partially remedied.

As a solution to the above-described objects underlying the invention, the invention proposes a method having the features of claim 1. The inventive method is used to provide a closed water supply of a cylinder-like connection piece of a concealed pipe of a water pipe, which on a concealed side of a Wall cladding is disposed through the wall cladding to a room side of the wall cladding. The spigot is formed in a conventionally known manner to ensure a connectability of a valve. For this purpose, the connecting piece, for example, have an external thread or an internal thread or a smooth cylindrical wall, on which a crimp can be made. The wall cladding can be ensured for example by plasterboard and / or a plaster layer with tiles and / or a plaster. The wall cladding serves the purpose of preventing a view from the room to the concealed pipe after completion of the room installation. Accordingly, the flush pipe is arranged with its connection piece on the flush side of the wall paneling. In the method according to the invention, in order to prepare a construction of the wall cladding, the connecting piece of the flush-mounted pipe is sealed watertight with a construction stopper. Construction plugs and connecting pieces can be designed to correspond to each other in a known manner, for example, have mutually corresponding threads or mutually corresponding crimping or connected to each other via a connector which is formed on one side corresponding to the connection piece and on the other side corresponding to the construction plug , A large number of implementation possibilities of a connection between connecting pieces and construction plugs is known to the person skilled in the art, via which a construction plug can be connected to the connecting piece in such a way that the construction plug closes off the connection piece in a watertight manner. According to the invention for preparing the construction of the wall covering a sealing sleeve with a mounting portion which is arranged at a first axial end of the sealing sleeve, circumferentially disposed around the connecting piece of the concealed pipe and on the Fixed connecting piece and arranged the connection piece waterproof sealing construction plug within the sealing sleeve. The sealing sleeve thus surrounds with its first axial end of the connecting piece and circumferentially around the connecting piece waterproof sealing. In this case, the sealing sleeve is fixed on its mounting portion to the connecting piece. Both this sealing arrangement of the sealing sleeve around the connecting piece as well as the arrangement of the Baustopfens within the sealing sleeve thus takes place during the preparation of the construction of the wall paneling. Thus, the sealing sleeve provides a continuous guide, starting from the connecting piece, in which the construction plug is arranged. According to the invention, the continuous guide is provided by the connecting sleeve of the concealed pipe to the room side of the wall panel after the construction of the wall cladding, the construction plug is accessible from a second axial end of the sealing sleeve, which is arranged on the room side of the wall cladding. The second axial end of the sealing sleeve lies axially opposite the first axial end of the sealing sleeve. The sealing sleeve extends axially through the passage provided in the wall cladding and thus axially from the flush-mounted side to the room side of the wall cladding. In one embodiment of the method according to the invention, the construction plug is first connected to the connection piece, so that it seals the construction plug waterproof, after which the sealing sleeve is arranged around the construction plug and circumferentially on the connection piece. In another embodiment of the invention, first, the sealing sleeve is arranged on the connecting piece and then the Baustopfen introduced from the second axial end of the sealing sleeve and connected to the connecting piece, in which it closes the connection piece watertight. The connection of the construction plug to the connection piece can be known to the person skilled in the art, for example, the ways described above be realized. The sealing sleeve may preferably be formed in one piece. For example, the arrangement of the sealing sleeve can be realized to the connecting piece over that the sealing sleeve is slipped on the outside of the connecting piece or is screwed onto an external thread provided on the outside of the connecting piece. In one embodiment, the sealing sleeve can be realized by two half-shells, which are placed on both sides of the connection piece and connected to this and are also sealingly connected against each other, for example via a clamping connection.

The method according to the invention brings decisive advantages over the conventional methods described. By providing a sealing sleeve, which is arranged externally around the construction plug and connected to the connecting piece as explained, an unchanged closed water flow can be ensured over the entire construction process, starting from the connecting piece. Thus, in a first shell phase always the construction stopper can be arranged in the sealing sleeve and close the connection piece, which can be removed after completion of the shell during the fine installation of the construction plug from the spigot and then a fitting connection piece can be connected to the connection without this position is changed to the sealing sleeve relative to the connecting piece by the fitting fitting, just as before the Baustopfen, within the sealing sleeve is arranged. In this case, the fitting connection piece can be introduced from the second axial end of the sealing sleeve in the sealing sleeve. Particularly preferably, the sealing sleeve is circumferentially closed sealingly arranged around the connection piece. Then, in the event that a faulty connection of the fitting fitting to the connection piece a leak between the connecting piece and the fitting fitting is present, the sealing sleeve itself provide an outgoing from the spigot and closed to the room side of the wall panel continuous water supply, which then leaking leakage water to the room side of the wall panel leads, so that such leakage from the room are detected and resolved can. In addition, the method according to the invention makes it possible, via the corresponding installation of the sealing sleeve and the installation of the construction stopper adapted thereto within the sealing sleeve, to provide excellent sealing of the continuous guide to the space side of the wall cladding. For a craftsman who undertakes the construction of the wall cladding and seals the room side of the wall cladding, this seal can perform directly opposite the sealing sleeve. Since the sealing sleeve remains unchanged in its position during the entire construction process after its arrangement on the connecting piece, a seal between the room side of the wall panel and the sealing sleeve undergoes no further burden in the further course of construction. In a subsequent connection of a valve via a fitting fitting only the construction plug is removed from the second axial end of the sealing sleeve and then introduced from the second axial end of the sealing sleeve from the fitting fitting in the sealing sleeve and connected to the connecting piece. From the above results that for the implementation of the method according to the invention, the coordinated design of construction plugs and sealing sleeve is absolutely necessary. For the diameter of the Baustopfens and the inner diameter of the sealing sleeve must be coordinated so that the Baustopfen can be arranged in the sealing sleeve and is accessible from the second axial end of the sealing sleeve, can be detached from the connecting piece and removed from the sealing sleeve , By this mutually corresponding configuration of construction plugs and Sealing sleeve ensures that the position of the sealing sleeve relative to the connecting piece can remain unchanged after the sealing sleeve has been arranged on the connecting piece, which is associated with the advantages described above.

In one embodiment of the method according to the invention the sealing sleeve with its mounting portion is circumferentially closed watertight sealing arranged around the connecting piece. Particularly preferably, the mounting portion is placed for sealingly placing on the connecting piece with a mounting portion on the connection piece, which is arranged at the first axial end of the sealing sleeve. The sealing sleeve thus preferably comprises a mounting portion, which forms an axial portion of the sealing sleeve. The mounting portion preferably forms the first axial end of the sealing sleeve. About the slipping of the sealing sleeve over the connecting piece can be achieved in a very simple and effective manner a circumferentially closed watertight sealing of the sealing sleeve relative to the connecting piece.

Particularly preferably, the detachable connection is effected by means of a screw connection. Furthermore, according to the invention, it is particularly preferred after the construction of the wall cladding of the construction stopper to be removed to enable a connection of a fitting fitting to the connecting piece. As a result, a fitting can be connected to the connecting piece and thus to the water pipe from the room side. During the construction of the wall cladding, a sealing collar is preferably arranged in a circumferentially closed, watertight sealing manner on the sealing sleeve. Such a sealing collar has a planar extension, in which a recess is provided, in which the sealing sleeve can be arranged, wherein in the corresponding arrangement, the sealing sleeve around the sealing sleeve circumferentially closed watertight sealingly rests.
