While in the first case the sealing of the nozzle against the egg drinsren of ieton- or r-stroked / einnie so / ie its leveling in relation to the finished concrete or

second case finding the embedded channel! Difficulties

The task of the innovation is now to arrange the accesses or outlets to or on in the concrete or Screed-embedded installation ducts to simplify.

According to the innovation, this task is carried out with an as Molded part formed auxiliary released, its Abmessunpen the required shaft shape of the access or outlet as installation space for closure or built-in elements and that on an underground canal is attachable.

In order to create a manhole as access to an underfloor duct, with the innovation it is only necessary -Jas molded part at the desired location

to be attached to the channel cover, for example by gluing, and together with the i ^ anal in the concrete or pour screed. After the concrete or screed has hardened, the molded part is removed, which means that the Concrete or jistrich a shaft is obtained in which the desired and usual installation elements be used know .. To take out the To facilitate molded part from the hardened concrete or screed, this can expediently the shape to have a leech or pyramidal syrup »

In a preferred embodiment this is newunpsgemäise jroi'nteii mil üiueiu Απο «υ & νσΓοσϊιθϋ, which rests on the base plate of the underfloor duct, wherein a lid-like closure element each over the openings of the channel sections adjoining the extension is arranged. to prevent the penetration of liquid concrete or screed into the underfloor ducts. This refinement of the innovation offers the advantage that channels with different cross sections can be integrated into one Can open out into the shaft, which has proven particularly useful in the case of sewer branches. the locking elements be attached to each other with hasty elements (projections and slots).

It has proven to be useful in reiter to arrange the sides of the molded part according to the innovation, dowel-shaped support elements, some of which are in the Concrete or screed, are poured and after removing the standard part with the one in the same End protruding into the shaft as a carrier for installation elements · These ends can have screw holes have or be profiled in a suitable manner in order to fasten installation elements to make possible without effort.

For the formation of a shaft as access see below or outlet from the Ünierflurkanal 2, the whole thing is embedded in the concrete or screed forming a building wall or ceiling

In the execution of the l ^ eueruns according to FIG. 2 and FIG. 3, the molded tool 3 has an attachment 6 which rests on a floor tube 7 of a channel connection.

The concrete or screed body 15 protects the molded part 3 from being exposed to the shaft 12 from damage during construction site operations and thus at the same time contributes to a Reducing the risk of accidents; because iOrmteile 3 completely made of rigid foam would not withstand the loads occurring on a raw ceiling by craftsmen and the like without deformation, which creates depressions that act as a source of accidents.
