    The invention relates to a prefabricated, in particular precast concrete, ausgebil Deten shaft, in particular sump shaft, for installation in a building with a shaft bottom adjoining, circumferential shaft shell, with a connection reinforcement for connection to a building-side floor assembly and with a sealing device is provided as a barrier against creeping water coming from outside.
    DE 20 2011 050 175 U1 shows such a shaft. In this known arrangement, the connection reinforcement of the upper end face of the prefabricated manhole shell protruding reinforcing bars, which are to intervene in the locally produced, building-side floor assembly. This must therefore cover the upper end of the prefabricated manhole shell here. This requires the attachment of a formwork on the shaft inside, which is associated with a lot of effort. The known arrangement therefore proves to be not easy to install enough.
    On this basis, it is therefore an object of the present invention to improve a shaft of the type mentioned above with simple and inexpensive means so that installation with relatively little effort is possible.
    This object is achieved in that are provided to form the connection reinforcement of the circumferential outer shell side of the prefabricated component radially outwardly projecting reinforcing bars and that the sealing device is also associated with the circumferential outer shell side of the prefabricated component.
    These measures ensure that the top of the finished part of the locally produced, building-side floor assembly does not have to be covered. Rather, here the building-side floor arrangement can be easily connected to the side. The upper end face of the prefabricated component, which may be designed as precast concrete component, can therefore already be prepared at the factory as a finished manhole crown, so that a rework-free installation is guaranteed. The attachment of a formwork in the production of the building-side floor arrangement can be omitted here. Rather, the already set prefabricated component according to the invention itself acts as shuttering in the manufacture of the building-side floor arrangement. The measures according to the invention thus advantageously make it possible to produce a ready-to-install prefabricated component with a ready-made shaft crown and thus allow a high degree of ease of assembly and rational operation during installation.
    Advantageous embodiments and expedient developments of the higher-level measures are specified in the dependent claims.
    Conveniently, the manhole crown can be formed from the beginning as exposed concrete surface in a finished part made of concrete. This results in a finished manhole crown to which the on-site building-side floor assembly can easily connect with a level top.
    Another, particularly preferable training of the parent measures may consist in that the reinforcing bars are designed as in associated, shaft shell side provided thread screw-bolt. In this case, it is advantageously possible to attach the reinforcing bars also subsequently. The prefabricated component can therefore be initially stored and transported without the reinforcing bars and used on the construction site in an associated pit. Subsequently, the reinforcing rods can be screwed, which is still possible if one of the locally produced, building-side floor assembly associated reinforcement already exists. This results therefore a particularly high ease of installation. It is advantageously possible that the reinforcing bars in exchange for transport provided by means of a hoist eyebolts in the provided for this anyway, shaft shell side thread can be screwed. Here, the eyelets associated with the transport eyelets are simply used for the support of the reinforcing rods after removal of the lifting eyes, so that additional threads are not needed and accordingly corresponding costs can be saved.
    The circumferential outer jacket of the prefabricated component associated sealing device may be formed according to a first proposal as a circumferential, radially outwardly projecting collar. This forms a simple and obvious barrier against rising creeks. To form the collar can be provided an angular cross-section, preferably designed as a sheet metal ring, circumferential rim, one leg of which forms the collar and the other leg is attached to the outer periphery of the shaft shell. This results in a simple and inexpensive production. To perfect the sealing effect of the mounting flange can be advantageously deposited with a sealing element. Likewise, for this purpose, the projecting collar can advantageously be provided with a coating sealing against concrete.
    To simplify the installation of the reinforcing bars, these are expediently positioned above said ring.
    According to another proposal, the sealing device can be easily designed as mounted on the outside of the manhole shell, circumferential, consisting of a fresh concrete composite film sealing strip. The fresh concrete composite film is designed so that it expands on contact with water or fresh concrete, so that when bonding the concrete results in a tight connection. This can be further enhanced by a slight surface profiling of the composite film on the outside facing away from the manhole shell.
    Suitably, the sealing strip underlying fresh concrete composite film may consist of a polypropylene nonwoven, which not only has a good swelling effect on contact with fresh concrete, but also results in an ion exchange reinforced adhesive bond with the concrete, resulting in a particularly good barrier. This can be further enhanced by a coating based on a polymer hybrid. To fix the sealing strip may be provided an adhesive.
    Additionally or alternatively to the above-mentioned sealing strip, the sealing device may also have a preferably consisting of a thermoplastic elastomer, circulating swelling tape, which also expedient profiled at least on the outside facing away from the jacket to increase the effective surface and on the other hand by means of a swelling adhesive on the jacket is appropriate. Appropriately, the said swelling tape may be arranged upstream of another element of the sealing device, expediently the above-mentioned sealing strip, in the direction of sealing, whereby a particularly high sealing reliability is achieved.
    A further expedient measure may be that the shaft casing is provided with a circumferential, outwardly open groove, which is associated with the sealing device and preferably also the connection reinforcement. The groove proves to be advantageous as an assembly aid in the attachment of the sealing device.
    In embodiments with a comparatively thin wall thickness of the jacket can be provided to ensure a sufficient engagement depth of the reinforcing bars or the associated threaded bushes on ropes of a circumferential groove a circumferential radially outwardly projecting collar, which may also be associated with the sealing device. Both the groove and the federal government should be in the range of the altitude of a concrete floor slab of the building-side floor arrangement, resulting in a toothing between the shaft and the bottom plate and accordingly a support of the effect of the connection reinforcement is achieved. The lower shoulder of the groove or of the collar is also suitable in an advantageous manner for receiving a further sealing element upstream swelling band of the type mentioned above.
    [0016] Further advantageous embodiments and expedient developments of the higher-level measures are specified in the remaining subclaims and can be seen in greater detail from the following example description with reference to the drawing.
    In the drawing described below: Figure 1 shows a vertical section through a sump shaft, Figure 2 is a perspective view of the arrangement according to Figure 1, Figure 3 is an enlarged view of an upper portion of the arrangement according to
    Figure 1 in the installed state and Figure 4 shows a shaft in Figure 3 corresponding representation with a variant of
    Sealing device and Figure 5 shows a shaft with respect to the above examples comparatively thin
    Wall thickness.
    Main field of application of the invention are so-called pump sump shafts. Arrangements of this type are used where the lower level of an in-house sewer line, which is generally below the basement floor, is lower than the house connection to the public sewerage system, so that the wastewater from the lowest level of the in-house sewer line must be raised accordingly. For this purpose, located in the pump sump shaft, which is embedded in the basement floor, provided with a suitable pump collecting and conveying device.
    The pump sump shaft shown in Figures 1 and 2 consists of a cup-shaped shaft body forming, designed here as a prefabricated concrete prefabricated component 1, which can be mass-produced. The prefabricated component 1 contains an open-topped, bounded by a shaft bottom 2 and a subsequent encircling shaft shell 3, a not shown here collecting and conveying associated interior 4, which are accessible via at least one provided in the upper region of the shaft wall 3 wall recess 4a can. The prefabricated component 1 designed here as a prefabricated concrete component can be produced monolithically. But it would also be a multi-part design, for example in the form of a cup-shaped base and a recorded thereon, the upper shaft crown 7 containing essay frame conceivable that can be glued and / or pegged. The frame may be formed as the upper end face of the manhole shell 3 covering concrete frame, which would then result as a result of an immovable connection of the frame to the lower part of a quasi-monothlike execution. But even a gedgedelte or screwed metal frame would be conceivable, as shown in Figures 4 and 5.
    A sump shaft here present type includes in the installed state, as can be seen from Figures 3 to 5, with the upper portion of his coat to a usually the basement floor forming, building-side floor assembly 5, which in the preparation of the building before Place is made. The underlying the pump sump prefabricated component 1 is used before the creation of the building-side floor assembly 5 so in an associated pit that its shaft crown, that is its top, on the intended level of the top of the bottom assembly 5, which is subsequently prepared and to the previously already placed in position finished component 1 is connected laterally. In the example shown, the building-side floor arrangement 5 consists of a concrete floor slab 5a resting on the grown or poured underground, an insulation 5b received thereon, a screed support 5c resting thereon and a floor covering 5d thereon.
    In order to ensure a reliable connection of the prefabricated component 1 to the building side provided ground assembly 5, the prefabricated component 1 is provided with a connection reinforcement, which engages in the concrete base plate 5a. To form the connection reinforcement 3 projecting reinforcing rods 6 are provided in the present arrangement by the circumferential shaft shell 3 radially outwardly. These are placed in height so that they are in the installed state in the area of the concrete base plate 5a and engage in their production.
    The finished component of Figures 1 - 4 is here in the range of altitude of the concrete base plate 5a provided with a circumferential, outwardly open groove 17 into which the bottom plate 5a engages with a projection, so that there is a mutual teeth, which the effect of the connection reinforcement is supported. Instead of a groove could also be provided an outwardly projecting circumferential collar, as Figure 5 shows where such a collar 20 is provided. Here, too, results in a mutual toothing.
    Since the reinforcing bars 6 protrude from the shaft shell 3 radially outward, the shaft upper side, that is, the upper shaft crown, virtually connection element free and therefore requires no overlap by the building side to be provided floor assembly 5. This can therefore with level equal top side to the prefabricated component 1 connect, this acts in the manufacture of the bottom assembly 5 practically as formwork. The upper end face of the prefabricated part 1 remains visible and can be suitably prepared already during production as a finished shaft crown 7, e.g. in the form of a smooth exposed concrete surface, to which the floor covering 5d of the building-side floor arrangement 5 can be connected with level top side.
    In many cases, it is desirable to cover the interior 4 by an upper lid, not shown here. Such a lid can engage with its outer edge in an associated, provided in the region of the shaft crown 7, indicated in Figure 3 fold 8. In a monolithic embodiment of the fold 8 is integrally formed on the one-piece prefabricated component 1. In a multi-part design with upper concrete frame of the fold 8 is integrally formed on the concrete frame. It would also be conceivable, for forming a lid associated with a fold on the upper end face of the prefabricated component 1 to provide a circumferential metal frame 8a with an angular cross-section forming legs, as indicated in Figure 4. The frame 8a, whose size is suitably adapted to the contour of the outer periphery of the prefabricated component 1, would thereby cover the upper end face of the prefabricated component 1. This would be here to be prepared as a frame support surface.
    The projecting from the shell outside radially outwardly reinforcing bars 6 are arranged detachably. For this purpose, the reinforcing bars 6 are formed as in associated, shaft shell side provided thread 9 screw-bolt. To form the thread 9 are cast in the shaft shell 3 in the example shown, provided with a thread 9 forming internal thread threaded sleeves 10, as best seen in Figures 3 and 4 can be seen.
    Such threads 9 are also required for attachment of lifting eyes for transporting the prefabricated component 1 by means of a hoist and are therefore available after removal of the lifting eyes without further effort to accommodate the reinforcing bars 6. For this purpose, the lifting eyes are simply unscrewed and the reinforcing bars 6 are screwed. As a rule, two lifting eyes and accordingly two receiving threads are provided per shaft side. Experiments have shown that it is sufficient if the reinforcement device has a corresponding number of reinforcing bars 6, so that the existing thread 9 sufficient and therefore no further effort is required. Of course, it would also be possible to provide a plurality of such threads 9, if more rebars 6 should be required in an individual case.
    The reinforcing bars 6 are expediently designed as sections of a suitable rod material, to which a screwed into the thread 9 of the threaded sleeves 10 threaded shaft 11 is attached. In the example shown, the reinforcing bars 6 are formed as sections of a bar provided with a circumferentially interrupted ribbing. Of course, it would also be conceivable to form the threaded shaft directly to the associated reinforcing bar, or to form this total as a section of a threaded rod, wherein the thread forms a circumferential ribbing.
    The prefabricated component 1 is also associated with a sealing device, which serves to the
    Fug between the encircling shaft shell 3 and the surrounding, building-side floor assembly 5 shut off against coming from the outside creeping water. In a first embodiment underlying FIGS. 1 to 3, a collar 12 protruding radially outward from the shaft jacket 3 is provided to form the sealing device mentioned. This protrudes in the installed state, as can be clearly seen from Figure 3, in the bottom plate 5a, wherein the radial projection over the outside of the manhole shell 3 is so large that creeping water does not pass it and is therefore reliably retained.
    The collar 12 may suitably be provided with a sealing surface sealing relative to the concrete of the bottom plate 5a. This coating may be limited to the water side. As a coating material is a UV-crosslinked polymer in question, which connects to the concrete of the bottom plate 5a or at least has a high affinity for concrete. The collar 12 is located conveniently below the reinforcing bars forming the reinforcement device 6 and accordingly also below the associated threaded sleeves 9, so that previously mounted there lifting eyelets are not hindered by the radially projecting collar 12.
    At the radially inner end of the radially projecting collar 12 includes at a right angle to a mounting flange 13 which rests against the outside of the manhole shell 3 and is attached thereto and the collar 12 carries. Overall, this results in a cross-sectionally angular component in the form of a circumferential ring. The mounting flange 13 is in the example shown, as best seen in Figure 3, deposited with a sealing element 14, so that there is a sealing contact with the outside of the manhole shell 3. For fixing screws or pierced rivets 15 etc. can be used. An adhesive or clamping connection would be conceivable. The collar 12 or the garland containing this is expediently made of sheet metal. But also a use of plastic would be conceivable.
    In addition or as an alternative to a circumferential collar 12 provided in FIG. 3, the sealing device may also have a peripheral sealing strip 16, shown in FIG. 4 and attached to the outside of the shaft shell 3. This is designed so that it swells on contact with the wet in the production of the building-side floor assembly fresh concrete, resulting in a seal. For this purpose, the sealing strip 16 is produced from a fresh concrete composite film. This is suitably made of a polypropylene fleece, which may be provided with a coating based on a polymer hybrid, resulting in a particularly reliable, u.a. achieves adhesion and ion exchange based sealing. This effect can be further enhanced by providing the sealing strip 16 on the outside, that is to say with respect to the bottom arrangement 5, with a surface profiling which increases the surface area, for example in the form of a roughening or corrugation. The circumferential sealing strip 16 may simply be glued to the outside of the shaft shell 3 at the assigned location. But also a riveting etc. would be conceivable.
    In addition or as an alternative to the above-described sealing elements in the form of the collar 12 and / or the sealing strip 16, the sealing device can also, as Figure 4 further shows, another circumferential sealing element here in the form of an existing of a thermoplastic elastomer, etc. swelling tape 19, which is preferably attached to an outer surface of the shell 3 by gluing. For the production of the adhesive bond it is expedient to use an adhesive which swells in a wet environment. The swelling tape 19 swells like the adhesive in a moist environment and thus creates a seal against the upcoming concrete of the building-side floor arrangement, which is clearly supported by the source adhesive. To increase the surface, the swelling tape 19 may suitably have a suitable surface profiling, e.g. have a ribbed surface. It is sufficient if the surface profiling is provided on the side facing away from the jacket outside of the swelling tape 19. In the example shown, the swelling tape 19 is also provided with a surface profiling on its side facing the jacket 3, so that a lot of adhesive is absorbed and a good glued connection can be achieved.
    In the embodiment according to Figure 4, the swelling tape 19 is arranged upstream of the sealing strip 16 in the direction of sealing. Of course, it would also be conceivable to provide an additional source strip in the arrangement according to FIG. 3, which would then be arranged upstream of the collar 12 in the direction of sealing.
    In the examples described above according to Figures 1 - 4, the shell 3, as already mentioned, provided with an outwardly open, circumferential groove 17, which is located at the level of the concrete base plate 5a of the building-side floor assembly 5 and therefore when concreting the bottom plate 5a is filled with concrete, which results in a toothing of the present shaft with the bottom plate 5a and thus support the effect of the connection reinforcement in the form of the reinforcing bars 6. These should also intervene in the concrete of the bottom plate 5. The reinforcing bars 6 are therefore in the region of the groove 17, which may be assigned to the elements of the sealing device expediently.
    In the embodiment of Figure 3, the circumferential, below the reinforcing bars 6 arranged ring 12 is also in the region of the groove 17, wherein the mounting flange 13 abut the groove base and against this can be sealed by means of a him behind engaging sealing strip 16. In the embodiment according to FIG. 4, the sealing strip 16 covers the groove bottom. The additional swelling tape 19 is assigned to the lower, inclined shoulder of the groove 17. A similar arrangement of a source tape would also be conceivable in the arrangement according to FIG. The groove 17 are accordingly assigned both the elements of the connection reinforcement and the elements of the sealing device.
    The arrangement according to FIG. 5 corresponds in principle to the arrangement according to FIG. 4. Below, therefore, only the differences will be discussed, with the same reference numbers being used for parts remaining the same.
    In the arrangement according to Figure 5, the wall thickness of the shell 3 is substantially lower than in the above-described examples. In practice, it is assumed that a wall thickness of the order of 2 cm. In order nevertheless to ensure a sufficient depth of engagement of the reinforcing bars 6 and the associated threaded sleeves 10, here is the jacket 3, as already mentioned above, instead of the groove 17 of the above examples with a circumferential, radially outwardly projecting collar 20 is provided. This is like the groove 17 of the above examples also in the range of the level of the concrete bottom plate 5a of the building-side floor assembly 5 and receives the elements of the connection reinforcement in the form of the reinforcing bars 6 and the elements of the sealing device. In the example shown, a sealing strip 16 is arranged on the outwardly facing cylindrical surface of the collar 20. This is preceded by a swelling tape 19 which is attached to the lower shoulder of the collar 20.
    The precursor element underlying the figure 5 expediently consists of a fiber-reinforced, ultra-high-strength concrete (UHPC). At the top of the shell 3, as in the embodiment according to FIG. 4, a metal frame 8a for receiving a cover etc. is provided here.
    In some cases, it may be expedient if a shaft of this type present is provided with a thermal insulation 18. In this case, as indicated in FIG. 1, a prefabricated part 1 formed here as a prefabricated concrete component can be made of a suitable insulating material, such as foam, up to a desired height from the outside covering insulating shell. It would also be conceivable to additionally or alternatively provide an inner insulating shell. The outer thermal insulation 18 expediently ends in the region below the sealing device in the form of the collar 12 or of the sealing strip 16.
