Description

The invention relates to a method for sealing a pipe socket with respect to a surrounding wall surface as well as a mounting sleeve and a sealing set for this.

From the DE 102 01 854 B4 a sealing sleeve for sealing a pipe socket emerging from a wall is known, which has an integrally formed protective sleeve through which water emerging from the pipe socket is guided away from the wall.

Against this background, it was the object of the present invention to provide means for sealing pipe sockets which can be used flexibly and which optionally also enable pipe sockets lying in a depression to be sealed.

This object is achieved by a method according to claim 1, by a mounting sleeve according to claim 6 and by a sealing set according to claim 9. Advantageous refinements are contained in the subclaims.

According to a first embodiment, the invention comprises a method for sealing a pipe socket with respect to a surrounding wall surface with the aid of a sealing collar which has an elastic sealing collar. The “pipe socket” can generally be the end of a strand-like, typically cylindrical element, for example a pipe for gas or water installation, but also an electric cable or the like. The sealing collar is typically closed in a ring around an inner opening, the inner opening being delimited by the elastic sealing collar. Suitable sealing collars are, for example, from WO 2016/096790 A1 or EP 2 772 673 A1 famous.

1. a) Der Dichtkragen wird durch das Einschieben einer Montagehülse ausgestülpt.

The method is characterized in that the following steps are carried out one after the other:

1. a) The sealing collar is turned out by inserting a mounting sleeve.

• b) Die genannte Montagehülse wird zumindest teilweise über den Rohrstutzen geschoben.
• c) Die Montagehülse wird aus der Dichtmanschette zurückgezogen.

When "inserting a mounting sleeve", the sealing collar can be held stationary (stationary) and the mounting sleeve moved, and conversely, the mounting sleeve can be held stationary and the sealing collar moved, or a mixed form of these two variants can take place.

• b) The assembly sleeve mentioned is at least partially pushed over the pipe socket.
• c) The assembly sleeve is withdrawn from the sealing sleeve.

The mounting sleeve is typically a simple element, essentially cylindrical in its outer contour, which has a recess on at least one side for receiving the pipe socket or a part thereof. Typically, the assembly sleeve is tubular overall, that is, continuously hollow on the inside. The dimensions of the mounting sleeve are preferably such that it can be pushed over the pipe socket with little play or slightly tensioned, the pipe socket or its end being received within the mounting sleeve. The outer cross-sectional contour of the pipe socket is typically circular, although other shapes are also possible in principle (for example oval, polygonal, etc.). The same applies to the inner and outer cross-sectional contour of the mounting sleeve.

By everting the sealing collar, it is lifted out of the plane of the sealing collar so that it can also reach a pipe socket located in a depression when the edge of the sealing collar is on the plane of the surrounding wall surface. Such a protrusion can advantageously be brought about by the mounting sleeve. At the same time, the assembly sleeve helps to position the sealing collar around the outer circumference of the pipe socket. Step b) of sliding the assembly sleeve over the pipe socket takes place with the protuberance first.

After the assembly sleeve has been withdrawn from the sealing collar, the protruding sealing collar remains essentially in place and, due to its elastic tension, rests against the pipe socket (and / or the extension element described below) from the outside in a sealing manner.

Typically, the protruding direction of the sealing collar is retained when the assembly sleeve is withdrawn or it is folded over by turning it in the opposite direction.

In many cases, the wall surface surrounding the pipe socket is formed by the front side of a wall from which the pipe socket emerges. The “wall surface” is then oriented towards the room or accessible from the room. Optionally, the pipe socket can lie in a recess opposite such a wall surface.

Additionally or alternatively, the method can also be used when the pipe socket passes through a front wall and the rear side of this front wall facing away from the room is to be sealed off from the pipe socket. In this case, the "wall surface surrounding the pipe socket" is formed by the back of the front wall.

According to a further development of the method, the sealing collar is glued to the wall surface. For this purpose, the wall side of the sealing collar is preferably designed to be self-adhesive, at least in an outer edge area, the adhesive surface being covered by a protective film that is typically split in half before it is processed.

Furthermore, the gluing takes place preferably after the assembly sleeve has been withdrawn from the sealing sleeve. In this way, the inclusion of air cushions between the sealing sleeve and the wall surface can be avoided.

The above-described gluing of the sealing collar after the assembly sleeve has been withdrawn requires that the sealing collar is still accessible at this point in time. This is typically not guaranteed if the sealing collar is on the back of a front wall. In this case, it is preferably glued to the wall surface before step c), b) or a) of the method is carried out, i.e. before the mounting sleeve is withdrawn or before the mounting sleeve is pushed over the pipe socket or before the sealing collar is everted through the mounting sleeve .

Furthermore, as part of the method, the pipe socket can optionally be extended by an extension element such as a pipe socket. Such extension elements are often used in order to extend a pipe socket lying recessed behind the plane of the wall surface into an easily accessible position protruding beyond the wall surface. Advantageously, the mounting sleeve and the extension element are dimensioned so that the extension element can be pushed through the mounting sleeve on the pipe socket after step b) of the method and connected to the pipe socket, for example by screwing it in. In step c) the mounting sleeve is then withdrawn from the pipe socket and the attached extension element. The sealing collar lies against the exterior of the pipe socket and / or the extension element in a sealing manner.

The sealing collar can be essentially flat before the assembly sleeve is pushed in. Preferably, however, the sealing collar is already preformed as a protuberance before the assembly sleeve is pushed in. In this way it can be ensured that the protuberance reaches a sufficient size to bridge the distance between the plane of a wall surface and a recessed pipe socket to be sealed. By inserting a mounting sleeve, a preformed protuberance is stabilized, possibly deepened even further and, above all, easy to handle for assembly.

The sealing collar can optionally have a slot running radially towards the inner opening, so that it can be placed around a pipe or the like from the side.

As has already been mentioned several times, the pipe socket or its end can be recessed (recessed) opposite the plane of the wall surface. However, the method is not restricted to such a case and can also be used if the pipe socket protrudes completely or partially from the wall surface in the direction of the room.

According to a further embodiment, the invention relates to a mounting sleeve which is set up for use in a method according to one of the embodiments described above. As already explained, such a mounting sleeve can essentially have the shape of a hollow cylinder.

According to a preferred embodiment, the mounting sleeve has a conical outer contour. Small cone angles in the range from 0.5 ° to 5 ° (in particular cone angles of approx. 0.5 °, 1 °, 1.5 °, 2 °, 3 °, 4 ° and 5 °) are preferred. Such a mounting sleeve can evert out the sealing collar of a sealing collar with the narrower end first, the conical shape facilitating a subsequent retraction of the mounting sleeve while leaving the sealing collar behind.

According to a further optional embodiment, the mounting sleeve can have a longitudinal slot which can in particular run axially and / or radially through the entire sleeve. Such a longitudinal slot makes it possible to expand the sleeve radially if necessary in order to be able to place it more easily on a pipe socket, for example. Likewise, the sleeve can be narrowed radially through a longitudinal slot, if necessary, in order to be able to withdraw it more easily from a sealing sleeve, for example. Preferably, the longitudinal slot does not simply run in a straight line, but rather creates, for example, interlocking teeth which prevent axial displacement of the abutting sleeve sections. Furthermore, the end faces of the sleeve that are opposite at the longitudinal slot can touch one another or also have a spacing from one another (which can be used for radial narrowing when the sleeve is compressed).

• - A mounting sleeve which is set up to carry out a method according to one of the embodiments described above.

Finally, the invention also relates to the use of a mounting sleeve for carrying out a method according to one of the embodiments described above.

In the 1 until 4th are successive steps in the sealing of a pipe socket RS represented by a first embodiment of the method according to the invention.

How out 1 is recognizable, the situation that frequently occurs in practice should be assumed that the pipe socket RS recessed or set back from a surrounding wall surface WF lies. This can be the case in particular if the wall surface is formed by a front-wall installation. At the pipe socket RS it can be, for example, the end of a gas or water pipe provided with an (internal or external) thread.

The sealing of the pipe socket RS opposite the wall surface WF should through a sealing sleeve 120 take place, which is shown in the figures only in section. In a plan view, the sealing collar 120 be circular or square, for example.

10 shows in this regard a plan view of the side of the sealing collar facing away from the wall 120 , and 11 a plan view of the opposite wall side of the sealing collar 120 . In the figures, typical dimensions are also given in millimeters, although these can be suitably adapted depending on the application.

In the 10 Visible circular and centrally perforated surface of the sealing collar can be formed, for example, by a waterproof PU membrane (eg 0.2 mm thick). The sealing collar has in a central area 120 an elastic sealing collar 121 which typically annularly surrounds a central opening. In turn, is the sealing collar 121 outside all around from the (remaining) carrier material 122 the sealing collar, the latter being preferably self-adhesive on the wall side. This can be achieved, for example, with a butyl adhesive layer that is self-adhesive on both sides (eg 0.5 mm thick). Until the sealing sleeve is processed, the adhesive layer is covered by a removable protective film 122F covered which by a radial cut 123 is divided from the edge to the center of the sealing collar.

As 1 further shows is by inserting a tubular mounting sleeve 110 in the sealing collar 121 this in the direction of the pipe socket RS everted. The sealing collar is preferably preformed as a corresponding protuberance before the assembly sleeve is pushed in. The dimensions of mounting sleeve 110 and sealing collar 121 are so that the sealing collar is under Tension is applied elastically to the outside of the mounting sleeve.

How out 2 can be seen using the rigid mounting sleeve 110 the sealing collar 121 the sealing sleeve with the tip of the protuberance first around the pipe socket RS be arranged around. The pipe socket itself or its end is taken up by the interior of the mounting sleeve.

In this regard, the inside diameter of the mounting sleeve is 110 preferably just as large as the outer diameter of the pipe socket RS so that the mounting sleeve is relatively close to the pipe socket.

3 shows a frequently occurring intermediate step, which can, however, optionally also be omitted. This is an extension element 130 with the pipe socket RS connected, for example by being screwed into an internal thread of the pipe socket with a corresponding external thread. The extension element can, for example, have the shape of a pipe section and serve to move the connection plane of the pipe belonging to the pipe socket over the wall surface WF to highlight.

4th shows the retraction of the assembly sleeve as the next step in assembly 110 , with the turned-out sealing collar 121 is not pulled, but from the outside on the pipe socket RS and / or to the extension element 130 creates a seal. Retraction of the mounting sleeve 110 without entrainment of the sealing collar, a smooth, preferably conical outer contour of the mounting sleeve and preferably removal with rotary movements is facilitated.

A connection of the sealing sleeve 120 with the wall surface WF takes place preferably after removing the mounting sleeve 110 instead of. If the wall surface is plastered beforehand, the wall side is the sealing collar 120 protect it from the surface by packing it up. After the plaster has hardened, it can then be unpacked and stuck onto the primed plaster. In drywall construction (plasterboard, fiber cement board), on the other hand, it can be applied directly to the primed wall surface WF to be glued.

When gluing the sealing sleeve, a slotted cover sheet is preferably used 122F half removed from the adhesive surface, and the sealing sleeve is glued on. This means that there is no air cushion between the wall surface and the sealing sleeve.

• Zum einen kann die Montagehülse 110 an ihrer Außenseite leicht kegelförmig sein, damit sie leichter aus einem Dichtkragen zurückgezogen werden kann. Das Innere der Montagehülse hat dagegen typischerweise die Form eines geraden Kreiszylinders.

In the 5 and 6th is a mounting sleeve suitable for the process described 110 shown separately. The mounting sleeve 110 can be made of plastic (eg HDPE) and essentially has the shape of a circular cylindrical pipe section. However, the following design features are optionally available:

• On the one hand, the mounting sleeve 110 be slightly conical on its outside so that it can be more easily withdrawn from a sealing collar. The interior of the mounting sleeve, on the other hand, typically has the shape of a right circular cylinder.

Furthermore, the mounting sleeve 110 an axially extending longitudinal slot 113 on so that it can be expanded radially if necessary while expanding this slot. A head start 114 interlocks the two abutting parts of the mantle 111 the mounting sleeve 110 so that axial displacements along the longitudinal slot are prevented.

Furthermore, the mounting sleeve 110 a bead-shaped or conical extension 112 the upper (wider) axial end, which improves the handling of the mounting sleeve.

5 shows exemplary dimensions of the mounting sleeve 110 in millimeters, although these can be suitably adapted depending on the application. The wall thickness of the mounting sleeve is preferably between 1 mm and 2 mm.

In 7th is an alternative embodiment of a mounting sleeve in two perspective views 210 shown. In contrast to the mounting sleeve described above 110 is a first longitudinal slot here 213 executed with a simple step.

Furthermore, the mounting sleeve 210 on the first longitudinal slot 213 opposite side a second longitudinal slot 215 on, which is wedge-shaped in the longitudinal direction from the upper edge to just before the lower edge of the mounting sleeve 210 runs. As a result, the assembly sleeve can be compressed radially in the upper area so that it can be more easily withdrawn from a sealing collar. The outer shape of the mounting sleeve 210 therefore no longer necessarily has to be conical, but can be cylindrical.

the 8th and 9 show schematically two successive steps in a modification of the above-described method for sealing a pipe socket RS against a surrounding wall surface WF .

The pipe socket RS stands out from a primary wall M (for example a building wall), and at a distance from this wall M should be comparatively thin pretext VW (e.g. a chipboard). Furthermore, the pipe socket RS against this pretext VW - more precisely the back of the prewall facing away from the room - are sealed so that the latter is the “wall surface WF “Represents.

8th specifically shows the situation that a mounting sleeve (for example the mounting sleeve 110 or 210 according to the above figures) already in a prepared hole in the pretext VW was plugged. The sealing sleeve 120 is at the back WF the pretext VW glued around the hole, which was done before inserting the mounting sleeve 110 in the pretext VW or afterwards. Through the mounting sleeve 110 becomes the sealing collar 121 the sealing sleeve in the direction of the pipe socket RS everted.

An arrow is in 8th indicated that the pretext VW is then moved in the direction of the primary wall M, the mounting sleeve 110 over the pipe socket RS is pushed and the latter by the pretext VW passes through.

9 shows the result of this process, being the pretext VW was fastened by means not shown in detail at a given distance from the primary wall M. After this fastening of the front wall, the mounting sleeve 110 withdrawn. The sealing collar 121 can keep its direction of protuberance or - as shown - be folded in the opposite direction. In both cases, due to its elasticity, it lies tightly against the outer circumference of the pipe socket RS to ensure a secure seal between pretext VW and pipe socket RS to ensure.
