Description

The invention relates to an angular drain for flat roofs with an enclosure protruding over the roof surface, with a drain pipe guided through the enclosure and with a flat sealing element having a recess.

An angular sequence of the type mentioned above is the DE 200 02 607 U1 to be taken from the applicant. The term “attic”, which is used in technical jargon, is to be understood as encompassing. The known angled drain comprises an elastic sealing element, called a sleeve, and a plate body with a recess for connection to the drain pipe via a pipe socket. This angular drain has proven itself, but there is a need for a more stable design, which can at the same time ensure a barrier-free drain with increased tightness at the same time.

This object is achieved by the features of claim 1. The subclaims relate to preferred embodiments of the invention.

The two drain bodies can each comprise a pipe socket and a partially annular flange body connected to it, which merges into an angled flange section via a bending edge, so that the flange body forms an L-shaped configuration with the flange section when viewed from the side.

The pipe sockets can be slid into one another and form a locking connection in that, for example, circumferential locking ring elements are introduced on the inner pipe socket and counter-locking elements are partially distributed on an inner surface of the second pipe socket.

A reverse arrangement of the locking elements is also possible, in which the partial locking ring elements are arranged on an outer jacket of the inner pipe socket and the circumferential locking ring elements are arranged on the inner surface of the second pipe socket.

An advantageous, irreversible toothing and bracing area of the sealing element can be formed by the latching connection.

At least one flat sealing element with a recess adapted to the inner pipe socket, for example a circular sleeve made of elastomer, plastic or bitumen sealing sheeting, can be placed between the drain bodies. When the two drain bodies are pressed together, the flat sealing element inevitably assumes an L-shape.

The drain body can consist of weather-resistant hard plastic, for example thermoplastic polymers such as PVC or ABS plastic or a corrosion-resistant metal alloy. The drain body made of hard plastic can be fiber-reinforced.

The two drain bodies with the sealing element flanged in between represent an angular drain, which can be inserted with its two pipe sockets into a feed-through opening on the parapet so that it rests tightly with its larger flange body on an inner surface of the parapet and with the flange section on the roof surface . The lead-through opening can have a gradient of 1 ° to 5 °, preferably 2 °. The drain pipe of any length inserted into the feed-through opening can be glued tightly to the pipe socket of the angled drain.

With the angular drain according to the invention, any sealing sheets can be permanently fixed against external tensile forces by the irreversible pressing with the clamping flange bodies.

In addition, additional pressing elements, for example sealing ribs introduced on the flange bodies, can ensure increased tightness between the sealing membrane and the flange bodies of the angled drain.

Furthermore, at least one of the flange bodies can be permanently glued to the built-in sealing element, e.g. B. with a weather-resistant sealant and adhesive.

It is of great advantage that the rainwater can run off unhindered, essentially without accumulation edges and other obstacles.

The same or similar elements can be provided with the same or similar reference symbols in the following figures. Furthermore, the figures of the drawing, their description and the claims contain some features in combination. It is clear to a person skilled in the art that these features can also be considered individually or they can be combined to form further combinations that are not described in greater detail here. The invention also expressly extends to those embodiments which are not given by combinations of features from explicit references back to the claims, with which the disclosed features of the invention can be combined with one another as required, insofar as this is technically sensible. The exemplary embodiments shown in the figures are therefore only of a descriptive nature and are not intended to restrict the invention in any form.

The terms used in the following: "upper", "lower", "inner" refer to the arrangement of the drain body or the angled drain shown in the drawing before or after installation on the flat roof.

In 1 , 2 and 3 is a "first" named drain body 1 shown, which consists of a pipe socket 4th and a partially annular flange body 2 composed. On the flange body 2 is a round recess 3 arranged that is slightly larger than the inside diameter of the pipe socket 4th is. The flange body 2 goes over one of the recess 3 tangent bending edge 6th into one at an obtuse angle β curved flange section 8th about, as it is particularly evident in 3 you can see. The angle β , measured between the flange section 8th and one through the partially annular flange body 2 defined level E. is 92 °.

Furthermore is the 1 , 2 and 3 a second drain body 11th to be found, comprising a second pipe socket 14th and a second partially annular flange body 12th with recess 13th , which has a bending edge 26th into one at almost the same angle β curved flange section 18th transforms.

The flange section preferably has 8th an angle that is 2 ° to 3 ° larger β on than the flange portion 18th , whereby a stronger compression of the sealing element 7th is guaranteed.

It should also be mentioned that the flange section 8th , in the compressed state, with the complementary recess of the flange section 18th flush with the surface, whereby a barrier-free drainage of the roof surface to be drained is achieved. The flange section 18th is for this purpose preferably in a recess below the flange section 18th running sealing membrane laid.

The second pipe socket 14th has an inside diameter D2 having an outside diameter D1 of the first pipe socket 4th does not fall below, so that the pipe socket 4th ; 14th can be pushed into each other. Here is the second pipe socket 14th shorter than the first; After sliding into one another (cf. 4th and 5 ) the inner pipe socket protrudes 4th over a free end 22nd of the pipe socket 14th out. This in turn enables a drain pipe to be pushed on 5 (see. 8th ) on the inner pipe socket 4th until said end 22nd of the pipe socket 14th . Preferably the drain pipe is 5 between the two pipe sockets 4th ; 14th inserted and glued there.

Furthermore are on an outer jacket 10 of the pipe socket 4th circumferential locking ring elements made of hard plastic 15th (see. 1 ) introduced whose tips, not shown, point outwards. Accordingly, are on the inside 17th of the shorter pipe socket 14th arranged complementary counter-locking elements. The counter-locking elements are preferably designed as partial locking ring elements 16 , in other words, on the circumference of the inside 17th distributed sections of the locking ring elements (cf. 2 and 3 ) executed.

Reference number “7” is a sealing element, indicated by a dashed line, with an outer diameter of the pipe socket 4th matching recess 23 designated. The sealing element 7th is made in the present case in the form of a flexible, 1.5 to 5 mm, preferably 4 mm thick, circular elastomer sleeve. Furthermore, on both flange bodies 2 , 12th circumferential sealing ribs 19th introduced, which during the later pressing of the two drain body 1 ; 11th engage with the softer material of the elastomer sleeve in between.

In 4th , 5 . 6 and 7 are drain bodies pressed together 1 ; 11th - for the clarity of the drawing - without a sealing element 7th shown. As from the 4th and 5 visible, the upper, inner pipe socket protrudes 4th over the free end 22nd of the shorter pipe socket 14th out. Furthermore, in 5 a schematically indicated latching connection 30th shown, formed by the aforementioned locking ring elements 15th and 16 .

One from the drain bodies 1 ; 11th and a sealing element flanged therebetween 7th compound angle sequence 100 is in 9 shown. Not only the interlocking locking ring elements ensure increased stability and tightness 15th and 16 (see. 1 until 3 ), which is the sealing element 7th Press together on both sides, but also the sealing ribs 9 , 19th (see. 3 and 7th ) and, last but not least, permanent bonding of the sealing element 7th at least with the smaller flange body 2 .

As the 8th shows, protrudes over a flat roof waterproofing level 25th an attic (enclosure 20th ) with a through opening that is slightly inclined towards the outside 24 , in their inlet area 27 the angular sequence 100 with its two pipe sockets 4th , 14th installed and there by means of screws, not shown, on the enclosure 20th and is attached to the flat roof. The screws are over on the flange body 12th distributed peripheral openings 28 (Screw head mounts) screwed in. That in the through hole 24 inserted drain pipe 5 forms with the flange body 2 ; 12th an angle α from value 91 ° to 95 °, for example about 92 °.

As a result, there is a barrier-free corner drainage 100 created, which is characterized by increased, permanent stability and tightness, its locking connection 30th an irreversible tooth and tension area 21 (see. 8th and 9 ) of the sealing element 7th forms.
