Description

This Invention relates to a shaft body or the like, especially in a soil installable hollow body, with at least one on an outside of a shaft body wall arranged, facing the environment of the shaft body Pipe socket for connecting a discharging from the shaft body and / or feeding pipeline or the like Component.

Such Shaft bodies are known from the prior art. she find their use among other things as collecting shafts, Felling shafts, cisterns, separators, pump stations, Manholes for sewage or rainwater installations, Drains or gullies. Of course they are but also includes piping to which an afferent and / or laxative further pipeline or a similar Component to be connected.

Out In the prior art are specially shaft body and in particular Plastic shaft body known in which such a pipe socket is arranged on the outer wall so that it faces outward, that is, protruding toward the vicinity of the shaft body. A Pipeline or similar component attached to this shaft body can be connected, then, for example, over a corresponding connection sleeve with this protruding pipe socket get connected.

adversely However, it has been found here that during installation of the shaft body in a soil in the region of this protruding pipe socket a Compaction of the adjacent soil material, in particular with vibrating plates or similar machines, mostly incomplete succeed. Moreover, it comes down to this protruding Component often damaging during installation or the transport.

This problem bypasses among other things the publication JP 11293693 A , Disclosed here is a way to connect a pipe by means of a connection sleeve to a sewer manhole. The sleeve is made of a flexible material and is partially pushed onto the pipe end of the pipe to be connected. The shaft-side end of the sleeve is then turned inside out and inserted into an opening provided for the connection in the wall of the shaft. By means of a clamping ring and a corresponding clamping device, the everted part of the sleeve is then pressed against the edge of the wall opening.

adversely However, here is the very expensive and therefore error-prone Connecting the pipe to the shaft.

present Invention is therefore the object of a shaft body of the type mentioned in such a way that the simple and secure connection of a pipeline or a similar component to the shaft body while improved handling and in particular ensures installation capability of the shaft body is.

These Task is by a shaft body according to claim 1 solved.

Especially So this task is done by a shaft body or similar, especially in a soil installable hollow body, with at least one on an outside of a shaft body wall arranged, facing the environment of the shaft body Pipe socket for connecting a discharge from the shaft body and / or feeding pipe or a like component solved, wherein the pipe socket in a Wandungsrücksprung the shaft body wall is formed such that the Outside of the shaft body wall in the area of the pipe socket is substantially free of projections.

Essential is that so the pipe socket in a Wandungsrücksprung at the shaft body wall of the shaft body is trained. This allows the formation of a shaft body without disturbing protrusions on the shaft body wall, making this particular much easier than off the shelf known in the art, can be installed in a soil and the soil itself is more uniformly compressible in this area. Compared to the known from the prior art pipe socket, the environment side of the outer wall of the shaft body stand out, is reduced due to the non-vaulted training of the shaft body according to the invention also the risk of damaging the pipe socket during of transport etc. considerably.

Preferably surrounds a recessed formed by the Wandungsrücksprung Area the pipe facing to the environment substantially annular. U. a. gives this annular recessed Area the pipe socket within the shaft wall a high stability.

Preferably, a connecting portion is provided on the pipe socket, for receiving a plug-in, screw or similar coupling sleeve on the pipe or vice versa. This allows safe and easy connection of the pipeline to the shaft body. Here are all known from the prior art methods and devices for connecting pipes applicable to other pipelines or manholes.

Preferably the Wandungsrücksprung has a socket clearance, for receiving the pipeline or a plug, screw or similar coupling sleeve. This muff free space on the one hand guarantees easy recording or connection with the Pipe socket, but it also allows the use of the recessed area as additional Arretierungs-, fixation or sealing element. That's the way it is possible the wall recess and the pipe socket so complementary to the pipeline or a thereto trained sleeve that this has a resulting Press fit between the wall of the Wandungsrücksprunges, the pipeline and the pipe socket is locked. In this context It is conceivable between pipe socket and wall of Wandungsrücksprung so form a kind of annular groove into which the pipeline or their Muff inserted accurately.

By a minimization of Wandungsrücksprungs or the socket free space In addition, the stability of Wandungsrücksprungs and increased the formed on the shaft body pipe socket become.

Preferably is at the wall recess and / or on the pipe socket at least a locking device provided with the pipeline in in particular releasable locking engagement can be brought. about the locking device on Wandungsrücksprung can so for example a plugged onto the pipe socket pipe or a plugged onto the pipe socket pipe sleeve also rohraußenseitig be locked on the pipe socket. Instead or at the same time Of course, such a lock can also be over a locking device on the pipe socket itself. In In this context, all locking, clamping, adhesive or even locks with independent locking aids, as clamps, etc., applicable, preferably a releasable Connection between pipeline and shaft body is formed.

Instead of Of course, a locking device is also possible corresponding sealing devices or combined locking-sealing devices to use the tubing substantially fluid-tight on the shaft body to fix. Of course, such a sealing device also carries for locking the pipe socket, in particular via frictional forces at, so this here also under the term locking device should be subsumed. So it is possible, for example provide sealing rings on the inside of a pipe sleeve, which are essentially fitted accurately on the pipe socket can and so on the one the pipe socket and the pipe or its sleeve seal against each other to the other but also fulfill a locking function.

Preferably is the Wandungsrücksprung to the environment in particular conically widening trained. Such an execution contributes significantly to stabilization the pipe socket in Wandungsrücksprung and also for stabilization the Wandungsrücksprunges itself.

Preferably the pipe socket is integral with the shaft body wall educated. In particular, in the formation of the shaft body as a plastic shaft is such an integral training of the Pipe socket advantageous due to a very inexpensive manufacturability.

Preferably the pipe socket is detachable as a stand-alone Component arranged on the shaft body wall. Such Embodiment is particularly suitable for shaft bodies made of concrete or a similar building material. Also possible this standardized shaft body to different Adjust ambient conditions, such as the diameter to vary the pipe socket. So can a corresponding independent Pipe socket element via connecting elements, in particular Screws, at an opening in the shaft body wall and in particular in a Wandungsrücksprung on the shaft body wall be attached to later connect a pipeline. If, on the other hand, no pipe socket is necessary on the shaft body, It is possible instead of the pipe socket a corresponding Blind cover to attach to close the opening.

The shaft body preferably has a blind cover which can be detachably arranged on the wall recess and / or on the pipe socket in such a way that it covers the wall recess substantially completely and in particular at the same level as the outside of the shaft body wall. This blind cover allows, for example, the installation of the shaft body in a floor when a pipe socket formed on the shaft body is not needed. Of course, it is also conceivable in this context to connect the blind cover via corresponding sealing devices substantially fluid-tight with the pipe socket or the shaft body. The fastening means for securing the blind cover to the shaft body can, as already mentioned above, be provided on the wall recess and / or on the pipe socket. Again, all known from the prior art devices are applicable. It is also conceivable in this context to form the blind cover integral with the shaft body and, for example, only with to provide a predetermined breaking point, so that it can be broken if necessary from the shaft body wall.

Further Embodiments of the invention will become apparent from the dependent claims.

in the The invention is based on several embodiments described by the accompanying drawings closer be explained. Hereby show:

1 an isometric view of a first embodiment of the invention;

2 : Isometric detail of a pipe socket of the embodiment 1 ;

3 : a longitudinal section through the embodiment of 1 ;

4 : an isometric view of a cross section through the embodiment of 1 ;

5 : a longitudinal section of the embodiment of 1 in detail with the representation of a connectable pipeline;

6 a longitudinal section of a second embodiment in detail with the representation of a connectable pipe; and

7 : A longitudinal section of a third embodiment in detail with the representation of a connectable blind cover.

in the The following are for the same and equivalent components the same reference numerals used, sometimes to distinguish High indices find their use.

1 shows an isometric view of a shaft body 1 , to the over a pipe socket 8th a pipeline 10 (please refer 5 ) is connectable. The shaft body 1 is formed in this embodiment as a plastic shaft body and so in a floor 9 (please refer 3 ) can be installed, that compacted soil stabilizing at the shaft body wall 2 pending.

Has in a shaft body according to the prior art, a pipe socket for connecting a pipe obstructs the compression of the adjacent soil material, so provides in 1 illustrated pipe socket 8th at the shaft body 1 no longer such a problem. Because of the pipe socket 8th in a wall recess 12 the shaft body wall 2 is formed such that the outside 4 the shaft body wall 2 in the area of the pipe socket 8th essentially free of projections, the shaft body can be 1 among other things simplest to install in a soil and the adjacent soil, especially in the area of the pipe socket 8th , evenly compress. In addition, the pipe socket 8th by his inventive training in Wandungsrücksprung 12 at the shaft body 1 protected so that there is no damage during transport or installation etc.

2 shows the embodiment of the Schachtköpers invention 1 in the area of the pipe socket 8th in an isometric detailed view. It can be seen that the pipe socket 8th annular from a recessed area 14 of the wall recess 12 is surrounded. In addition, the Wandungsrücksprung 12 essentially geometrically similar to the pipe socket 8th formed, which on the one hand increases its stability to the other but also the protection against environmental influences. In particular, such a geometric design leads to a protection of a connected pipe or a sleeve formed on the pipe (see 5 ).

The embodiment of 1 is in the 3 and 4 shown in a longitudinal section or in a cross section. Visible here is the very thin-walled design of Schachtkörperwandung 2 of the shaft body 1 and integral with this shaft body 2 trained wall recess 12 in which the pipe socket 8th to the outside, in the direction of the environment 6 is formed pointing. Consequently, the Wandungsrücksprung protrudes 12 in the interior 7 of the shaft body 1 into it. Of course, it is possible instead of the integral design of the pipe socket shown here 8th at the shaft body 1 a pipe socket also to be designed so that he, for example, via corresponding fasteners in Wandungsrücksprung 12 is positionable. Visible is further that the pipe socket 8th only so far from the Wandungsrücksprung 12 or the recessed area 14 protrudes that the shaft body wall 2 in the area of the pipe socket 8th essentially free of projections.

Unlike the previous ones 1 and 2 is in 3 the shaft body 1 shown in the installed state. It becomes clear that the shaft body 1 here in a floor 9 is built in, that this on the outside 4 of the shaft body 1 pending. It is also recognizable that due to the projection-free design of the pipe socket 8th in such a way that it does not have the outside 4 the shaft body wall 2 protrudes, a uniform compaction of the soil 9 also in the area of the pipe socket 8th , for example, one on the surface 11 patch vibrating plate or similar compression devices is possible.

Next in the 3 and 4 It is evident that the Wandungsrücksprung 12 to the outside 4 or to the environment 6 of the shaft body 1 is formed conically widened. This gives the pipe socket 8th in his training in Wandungsrücksprung 12 or in the receding area 14 the necessary stability.

In 5 is now the embodiment of 1 in a detail longitudinal section and a connectable pipeline 10 shown. This has for connection to the pipe socket 8th or to one on this pipe socket 8th trained connection extension 16 via a complementary to this compound extension 16 trained plug-in sleeve 18 , about which they essentially fit exactly on the pipe socket 8th can be plugged. To between the pipeline 10 and the pipe socket 8th to produce a substantially fluid-tight connection, has the plug-in sleeve 18 In addition, a circumferential sealing device 26 in the form of a sealing ring. This guarantees next to the fluid-tight connection and a locking of the pipeline 10 on the pipe socket 8th about friction forces.

As in 5 clearly, is the Wandungsrücksprung 12 so he designed for the pipeline 10 or the plug-in sleeve formed thereon 18 forms a sleeve clearance, so that the sleeve 18 in the wall retreat 12 can initiate.

6 shows a further embodiment of the invention in one 5 similar longitudinal section. The shaft body shown here 1 or the pipeline shown here 10 However, they differ in the formation of a corresponding locking device 20 . 22 at the wall retreat 12 or the socket 18 , So is the Wandungsrücksprung 12 a locking extension 20 provided, after pushing the plug-in sleeve 18 the pipeline 10 with a complementarily formed Arretierungsfortsatz 22 at the socket 18 comes in locking engagement and so the pipeline 10 in their position on the pipe socket 8th guaranteed. In this context, it should be mentioned that, of course, instead of the plug-in socket shown here 18 Other sockets, such as threaded sleeves or similar known from the prior art connecting means for connecting a pipe with a pipe socket can be applied. This also applies to the locking devices used for this purpose.

7 finally shows a third embodiment of the shaft body according to the invention 1 , again in one too 5 similar longitudinal section. Shown here is not a pipe but a blind cover 24 , the so on the pipe socket 8th detachably arrangeable is that he the Wandungsrücksprung 12 Environmentally substantially complete and in particular level with the outside 4 the shaft body wall 2 covered. The blind cover 24 also has sealing devices again 26 on which a fluid-tight connection with the pipe socket 8th allow and also contribute to locking over frictional forces. To improve the locking effect, it is also conceivable, for example, in the area of the outside 4 of the shaft body 1 form corresponding blind cover recesses (not shown) to the blind cover 24 , after slipping on the pipe socket 8th , completely free of projections on the shaft body 1 to position.
