Fora to create a socket pipe

The innovation relates to a form for producing a socket pipe made of concrete or reinforced concrete with a Symmetrical rubber sealing ring firmly anchored in the socket.

Socket pipes made of concrete or reinforced concrete are used for discharge of sewage and rainwater widely used. To seal the gap between the socket and rubber sealing rings are provided at the spigot end. In recent developments, preference is given to cc, the rubber sealing ring to be arranged firmly anchored on the inside of the sleeve. Such a seal has the advantage that the rubber ring is already brought into position during the pipe production and later only on the construction parts the pipes still have to be pushed into one another. For this it is necessary that the sealing ring already is firmly placed in a suitable position during pipe production, so that during concreting and a shift can no longer occur when stripping. A socket pipe configured in this way is from US-PS 22 3o 725 known.

The task of the innovation is to create a shape by means of which a symmetrical sealing ring can be easily Way is integrated into a socket pipe. By using a symmetrical sealing professional, Installation in the wrong direction is not possible.

The solution to the innovation in the aforementioned 7oral consists in that the one shaping the inner surface of the sleeve Foretell consists of a «molded ring part, the one inner cylindrical and one directed towards the socket end having conically widening ring area, and also on the cylindrical Fornringteil an im Cross-section of triangular auxiliary rubber ring with the same strange widening so that a Ringmu.Xde is formed in which a symmetrical sealing ring with external anchoring ribs is located.

In the structure of the mold according to the invention, the design of the Foxmringteiles, the auxiliary rubber ring part and the sealing ring is essential. Their interaction creates the inner surface of the sleeve as it is manufactured of the socket pipe and at the same time enables the sealing ring to be fixed in its intended position Position. The molded ring part and the auxiliary rubber ring can according to Holding the socket pipe out of the pipe one after the other can be removed and are available for reuse ready.

It is advantageous that the auxiliary rubber ring and the molded ring part form an annular recess which corresponds to the outer structure of the sealing ring.

Om to allow a safe position of the sealing ring, should in triangular in cross section sealing rings, the cylindrical and the conical portion of the mold ring member have the same height. In the case of triangular sealing rings with a flattened cross-section, the cylindrical area should have a greater height than the conical area of the molded ring part.

This enables in connection with the auxiliary rubber ring part a definition of the sealing ring from both sides in a safe manner.

For the safe positioning of a symmetrical sealing profile is et. required that the angle of the conical in the form ring part and in the auxiliary rubber ring Rise is the same. By using a symmetrical sealing profile, it is impossible that the sealing ring is installed in the wrong direction and the pipe connection is obstructed.

With the molded ring part and with the auxiliary rubber ring the angle of the conical rise to the pipe axis 15 to 25 °. This will allow the auxiliary rubber ring to be pulled out later Made relatively easy, but on the other hand also ensures a forced position of the rubber sealing ring. A rubber sealing ring with a 15 to 25 ° conical rise enables the automatic centering of the Pipes when pushed together with low insertion force at the same time.

The auxiliary rubber ring expediently has the cross section of a right triangle. This connects the radial plane in the pipe socket with the other shaping areas of the sealing ring and the flange on the ring molding as one largely flat surface. A look at the form put together for the pipe production is sufficient, to check the correct fit of the parts.

The auxiliary rubber ring 3 is placed on the outer side of the molded ring part 2 in the cylindrical area. Its surface 9, which is adjacent to the right angle, is the Main part of the tube facing. Form ring part 2 and auxiliary rubber ring 3 form with their equiangular conical surfaces 8 and 10 and one in between cylindrical section 7 of the molded ring part 2, the bearing surface for the sealing ring 4. The inner surface of the symmetrical, triangular-shaped sealing ring 4 with a flattened cross section is this spatial one Design of the surfaces 7, 8 and 10 adapted. The rubber sealing ring has a hammer head-like shape on its outer surface Projections 13 and a web 14. After the concrete has been poured into the mold, they are used to fix the Sealing ring 4 in the Mnffe. As soon as the pipe has hardened, the molded ring part can be moved in the axial direction of the pipe pulled out of the tube. Then the auxiliary rubber ring 3 is removed by at least one .. one point molded inward and from the sealing ring 4 is lifted. The conical surfaces 12 of the symmetrical sealing ring 4 cause the insertion the pipe is automatically centered with low insertion forces. The recesses 15 are chosen so that the deformed state with different gap widths to a planar load transfer and sealing leads. On the other hand, the profile sloping towards the socket base enables the pipes to be angled to one another.
