Downpipe socket

The innovation relates to a downpipe socket, in particular made of plastic.

For the drainage of essentially horizontal building ceilings, the roof drains are known by means of a drainage nozzle connected to the downpipe. These roof drains are mostly used to avoid structural damage caused by condensation provided with a thermal insulation jacket (DBP 1 215 069). These Protective measures would be inadequate, however, if not at least the first downpipe pieces connected to the roof drain as well would also be surrounded with a heat insulating material]. To this Purpose so far the space between the wall shaft and fur pipe has been filled with insulation wool. The associated Work takes a lot of time on the construction site.

The innovation is based on the task of remedying this deficiency by adding thermal insulation at the construction site to fix such downspouts. This is achieved in the case of the downpipe socket according to the innovation in that on its drainage pipe an elastic ring is provided at its lower or upper end, over which the drain pipe is at a distance surrounding protective jacket. With one like that

The double-walled, pre-fabricated downpipe socket has a sufficient thermal insulation effect given.

In order to increase this thermal insulation effect, after a Another feature of the innovation provided that the annular gap formed between the drain pipe and protective jacket with a insulating material is filled.

To in the transition from the socket of the downpipe socket or fitting to the roof drain socket or to other connection pieces to avoid unwanted thermal bridges, is also provided according to the innovation that the elastic rings on their outer end faces a connector or a cylindrical Have extension part or merge into such. This creates the respective transition or connection point also bridged double-walled, so that a continuous thermal insulation effect is guaranteed. Should several such downpipe stubs are connected to one another, it is advantageous here to wonn the elastic rings on their Transition into the connection piece or cylindrical extension part each have a circumferential separating groove that separates of the connection piece or cylindrical extension part (when transitioning to other types of pipe).

In the drawing, a downpipe socket according to the innovation is illustrated schematically. The downpipe socket consists of a drain pipe 1, at the lower and upper end of each one elastic ring 2, 2a is pushed. The upper ring 2a merges into a funnel-shaped connector 3, which is on its transition to the ring 2a has a circumferential separating groove 4. The lower ring 2 has a cylindrical extension part at the end 5 with a separating groove 4 at the transition between these two

Parts. A protective jacket 6 is supported on the elastic rings 2, 2a. The elastic rings 2, 2a form so together with drain pipe 1 and protective jacket 6 between the latter two an annular gap 7, which is preferably with is filled with a thermal insulation material.

Claims (4)

Protection claims: 1. Downpipe socket, in particular made of plastic, characterized in that an elastic ring (2, 2a) is provided on its drain pipe (1) at its lower or upper end, over which there is a protective jacket surrounding the drain pipe (1) at a distance (6) is supported. 2. Downpipe socket according to claim 1, characterized in that the between the drain pipe (i) and protective jacket (6) formed Annular gap (7) is filled with a heat insulating material. 3. Downpipe nozzle according to claim 1 or 2, characterized in that that the elastic rings (2 or 2a) have a connecting piece (3) or cylindrical on their outer end faces Have extension part (5) or merge into one. 4. downpipe socket according to claim 3, characterized in that the elastic ring (2 or 2a) at its transition into the connecting piece (3) or cylindrical extension part (5) has a circumferential separating groove (4, 4a).
