Roof, balcony or terrace drain

The invention relates to a roof, balcony or terrace drain according to the preamble of claim 1.

5 Sewers, which are mostly used in outdoor air, have a sliding fit between the outer walls of the inlet pipe and the insulation and compression ring, with which the insulation and compression ring can be set to the correct height with respect to the respective plant level of the inlet pipe. However, this sliding adapter forms a gap in the sealing ring which absorbs water which freezes below 0 ° C and, when melted, lifts the sealing ring from the outer walls of the inlet pipe and can thus flow past them. Because this happens most often, the sealing ring expands and its sealing-15 surface becomes so dirty that sealing is no longer perfect. This puts a considerable amount of water on the floor or ceiling.

The invention is based on the improvement of a roof, balcony or terrace drain such as the one mentioned above, so that the sealing properties of the sealing ring remain unchanged during the long service life of the drain.

The set task is solved by a drain according to the characterizing part of claim 1. The second sealing ring does not interfere with the movement of the insulating and compression ring when installed at the correct height 25, as they do not yet have to be axially attached. As soon as the sealing ring is attached to the insulating ring at the correct height position of the insulating ring and its compression ring, the second sealing ring 30 is also fastened axially so that it is pressed against the outer walls of the inlet pipe. In this modified state, it takes care of the sealing in the area above the sealing ring actually responsible for the sealing. Water seeping from above does not pass past the second sealing ring, since the lower sealing ring is able to fulfill its sealing function for a substantially longer period of time. In addition, the second sealing ring has a cold-insulating effect as long as the space between the lower and the second sealing ring does not cool down, so that, conversely, water leaking past the second sealing ring could freeze and lift the lower sealing ring.

A suitable embodiment of a drain according to the invention with a compression ring in a circulating trough-like insulation strip recess survives claim 2. The structural measures in the insulation strip and the compression ring for constructing a ring groove for the second sealing ring are simple and shape-free. The compression flange also has the advantage that, together with the outer walls of the inlet pipe, it defines a very small gap through which water can hardly flow up to the second sealing ring.

The embodiment according to claim 3 has been found to be expedient when, with the conical shape of the mounted second sealing ring, if a good position in the wall is achieved, it does not matter how strong the sealing strip is. Even when deformation occurs in the flange due to a drop in temperature, the conical inner wall presses the sealing ring into a sufficiently tight position and deforms it in a substantially vertical direction.

Another suitable embodiment is clear from claim 4. The features of this are important in that the second sealing ring does not prevent the installation of the insulating and compression ring, since it is not stressed in the radial direction by the longitudinal fastening. The embodiment of claim 5 is also expedient, in that the ring wall functions in two ways, firstly forming a boundary of the annular groove for the second sealing ring and secondly acting to hold the sealing strip in place with the insulating ring.

Another suitable idea is included in claim 6. This recess is easy to install due to its shape and ensures that the second sealing ring cannot be lost during storage and transport of the sewer spare part.

The feature of claim 7 is also important, where o-rings are available in virtually all conceivable sizes and cross-sections and are preferred. Such an o-ring can also be mounted for the above-mentioned purpose.

In connection with the figures, an embodiment of the invention will be explained by way of example.

The patterns are:

Fig. 1 shows an object of the invention in partial longitudinal section and Fig. 2 shows a second development of the inner ring wall of the compression ring.

The roof, balcony or terrace drain consists of an inlet pipe 2, an insulating strip 5 surrounding it on the outside in a slip joint and a compression ring 6 to be mounted and fastened to the insulating tape 5. The compression ring 5 can be articulated at its upper end to the front end 3 of the inlet pipe. 6 with the insulating tape 5 to a precisely predetermined height position in the inlet pipe 2, which continues further upwards (up to 25) when a second layer is installed in the compression ring 6 so that the inlet of the inlet pipe 2 moves higher.

The compression ring 6 cooperates with the insulating tape 5 to install the sealing tape 4 so that it acts as a moisture barrier layer, i.e. also that moisture does not pass along the outer sides of the inlet pipe 2 marked with the number 17 downwards or from below upwards.

The insulating strip 5 has a jewel-shaped recess around it, bounded by a funnel-shaped wall part 7, a flat bottom wall 12 and an inner wall 10 leading to its outer side 35 in the direction of the inlet pipe 2. The funnel-shaped wall part 4 to the insulating tape 5. It is glued to it by a compression ring 6 fixed by a fixing piece marked with a dotted line-5a to the depth of the insulating tape 5.

The compression ring 6 has a flat top wall 19, from which, concentric with the axis of the inlet pipe 2, a ring wall 18 runs downwards, the lower edges of which rest on the sealing strip 4 and press against these insulating strips 5. Further away, a flange 22 is arranged in the upper part of the inner ring wall 18 and in the extension of the roof wall 19 in the compression ring 6, which reaches near the outer sides 17 of the inlet pipe 2. The flange 22 has an inner circumference 20 as well as an approximately 15 horizontal lower edge 21. The ring wall 18 has an inner wall 23 which terminates in the lower edge 21 and which is located at a small distance behind the inner wall 10 of the insulating tape 5. The inner wall 10 terminates at the top with an edge 11 which runs almost perpendicular to the outer side 17 of the inlet pipe 2.

The edge 11, the inner side 23 of the flange 22 and the lower edge 21 delimit an annular groove 24a opening into the outer side 17 of the inlet pipe 2.

The second annular groove 15 is located in the special strip 5 and is delimited by a downwardly hanging annular wall 13 with an inwardly retracted support piece 14. In the ring groove 15 there is a first sealing ring 16 with a relatively larger cross-section, which is permanently located on the outer side 17 of the inlet pipe 2.

Between the annular groove 30a 24a placed above the annular groove 15, there is a second sealing ring 24 between the clamping ring 6 and the insulating strip 5, which is fastened axially to the insulating strip 5 during attachment of the clamping ring 6 and thus forms radially so that it extends to court 17 closely.

Il 5 81423

The second sealing ring 24 undoubtedly acts as a seal only after the compression ring 6 has been attached to place the sealing strip 4 on the insulating strip 5. Prior to that, it has not yet formed so radially so as to interfere with the movement of the insulating strip 5. Due to the lubricated outer side 17 of the inlet pipe 2, a sealing ring 16 with a larger cross-section interferes with the movement of the insulating tape 5 only to a negligible extent.

When the flange 22 with its inner side 20 is located very close to the outer side 17 of the inlet pipe 2, water penetrating possibly from here from the second sealing ring 24 can certainly prevent further penetration into the first sealing ring 16. In addition, the second sealing ring 24 insulates the space between itself and the lower sealing ring 15 broadly, that, conversely, the water passing through does not freeze in the intermediate space and thus cannot lift the sealing ring 16.

Figure 2 shows the clamping ring 6 enlarged with its inner wall 18, the inner side of which extends conically out of the flange 22 20. The lower edge 21 of the flange 22 is made somewhat weaker than the strength of the inner wall 10 of the insulating tape 5. The inlet pipe 2 has inner sealing rings, between the walls of which a second sealing ring 24 is arranged. Depending on the strength of the sealing strip 4, the compression ring 6 is fitted higher or deeper in the insulating strip 5. The conical wall 23 of the inner ring wall 18 presses the sealing ring 24 achieved at all heights. Thus, it is possible to use sealing strips 4 of different strengths in the insulating strips 5 and 30, in addition to guaranteeing the desired tightness of the inlet pipe 2.
