Device for casting the socket connections of pipes

The invention relates to a device for casting the air connections of pipes, in particular made of clay, cement, concrete od creates a sleeve-shaped extension of the other pipe. These known potting collars are provided with a parting line and a special closure _s so that they can be removed for new use after potting. because special operations are required for the closure. In addition, the cast mane sleeves must be made particularly strong, at least at their ends for fastening the closure. Material or at least at the points that come into contact with the hot potting compound with a layer made of particularly heat-resistant, high-quality material in order to be able to withstand the pouring of the hot potting compound several times without damage »

The invention has set itself the task of a device for potting the socket connections of pipes,

are avoided in which such Geesthacht ropes "This object is according to the invention essentially in _s achieved that the sleeve from a aufzusetzenden with pretension on the smooth pipe end closed ring is" This not only saves _s a special closure, but the Yergußmanschette may also consist of a well-feileren material created ₅ because it can be left on the tube and thus only one comes with the hot sealing compound into contact _o

Advantageously, the Vergußmanschette may be made of the plain end of one pipe enclosing ,, tubular ring member having a to-applying against the end face of the sleeve-shaped extension of the other tube sealing flange besteh en _o As a result Vergußmanschette is provided ₈ for the preparation thereof, only relatively little material is required _s because the tubular ring part and the sealing flange can only have a small wall thickness «. This at the same time makes it easier to put on the casting mane _s because the cuff can be spread more easily to the required diameter.

Advantageously, the tubular ring part "formed on the resting against the end face of the sleeve-shaped extension side of the sealing flange is thereby achieved _s that the tubular annular member protrudes into the to be cast gap ,, while the exterior of the sealing flange is free.

In a particularly expedient manner, the thickness of the tubular ring part increases towards its side having the sealing flange

wedge-shaped, thereby stabilizing the cuff achieved, since precisely the side of the tubular ring part having the sealing flange is made thicker and thus a Bending of the sealing flange is made more difficult *

In a particularly advantageous manner, it is in the to be potted Gap protruding tubular king part on its outer The outer surface is provided with at least one projection resting against the inner wall of the sleeve-shaped extension is in a simple manner at the same time a centering of the to be connected Pipes reached

Advantageously, "while the one or more provided on the tubular ring part projections of free to their ends tapered _s circumferential ribs formed thereby achieved ₉ that the inner tube check all around against the inner wall of the sleeve-shaped extension of the other pipe is supported _s wherein the tapered ends of the ribs can bend _s so that the tolerances in the pipe diameters can be compensated «,

Advantageously, when a filler opening for the potting compound and an air outlet opening are arranged in the sealing flange, the circumferential ribs are interrupted at least in the area of the openings. Moreover, the potting compound can thereby flow into the spaces between the ribs extending in the circumferential direction so that the _s Vergußmanschette is supported.

In the drawing, the invention is shown in an embodiment _s and that show?

Fig. 1 shows a pipe socket connection with an attached potting sleeve on average,

Mg ₀ 2 the Vergußmansehette in side view, partially in section and

Mg ₀ 3 the potting sleeve in plan view _β

The pipe socket connection shown in FIG. 1 is formed in a known manner from two pipes 4 and 5, ₉ of which the end 6 of the pipe 4 is smooth and the end 7 of the pipe 5 is widened in the shape of a socket. The pipes 4 and 5 are made of clay $ cement or concrete

The connection of the pipes 4 $ 5 takes place in such a way that the smooth pipe end 6 of the pipe 4 is inserted into the socket-shaped extension of the other pipe 5 and is connected to it in a sealing manner by the connection between the outer wall of the smooth pipe end 6 and the inner wall of the socket-shaped extension 7 is closed remaining gap with a potting compound 8 »for pouring of the gap is on the smooth pipe end 6, a ring 9 of elastic and / or acid- and oil-resistant material ₉ such as rubber _§ synthetic rubber od _e like. patched the ring 9 has einstückigenj one with him lip-like _{extension 10 on s} that applied against the inner wall of the socket-shaped extension 7 of the pipe 5. As a result, the sealing compound 8 cannot get into the interior of the pipe.

The other end of the gap is "closed during the casting with a Vergußmanschette 11, The Vergußmanschette is in one piece and also made of an elastic and / or acid- and oil-resistant synthetic rubber material such as rubber _{9 0} od the like," generated.

As can be seen in particular from FIG. 1, the potting sleeve 11 consists of a closed tubular ring part which can be placed on the smooth pipe end and which is integrally formed with the sealing flange 13 which rests against the end face of the sleeve-shaped extension 7 ". The inner diameter of the tubular ring member 12 is smaller than the outer diameter of the smooth pipe end 6 _r so that the ring member 12 is firmly seated with pretension "The inner lateral surface 14 et the Vergußmanschette 11 ist9 in particular from the Hg _0th 2 can be seen, slightly curved outwards in the middle, so that the edge strips of the inner jacket surface Cl 4 rest more strongly against the outer jacket surface of the smooth pipe end 6 »

The Vergußmanschette 11 is such set up on the smooth pipe end 6 _s that the tubular ring portion 12 protrudes into the to be cast gap ", the thickness of the tubular ring member increases its the Dichtungsfl; ange 13 side having a wedge shape to, and has at its conically extending outer lateral surface 15 four tapering towards their free ends, which create circumferential ribs 16 on inner wall of the _sleeve-like against the shaped extension. 7 Due to the conical outer jacket surface 15 of the tubular ring part 12, the rib 16 adjacent to the sealing flange 13 rests most strongly against the inner wall of the sleeve-shaped widening 7. With these

Ribs 16 is at the same time a centering of the to be connected Pipes 4 and 5 reached »

When arranging a filling opening 17 for the potting compound 8 and a tiuf tauslaß opening 18 in the seal flange 13 _S are also extending in the peripheral direction ribs 16 at least interrupted in the region of the apertures 17 ₅ 18 ', for the use of Tergußmanschette to lying tubes 4 and 5 the filling opening 17 and the air outlet opening 18 would each still have to be provided with a circuit

As already mentioned, the illustrated embodiment _s is just one example implementation of the invention and they are not restricted thereto Rather possible nor many other embodiments and applications.
