Definitions

  • the invention relates to a method for producing a socket pipe from a compactable mixture, in particular concrete, in a mold with a longitudinal axis aligned in the direction of gravity and a lying in the direction of gravity sleeve molding section, in which the mixture first in the socket molding section and then filled in ascending order in the remaining area of the mold and thereby compressed under the action of force.
  • the invention relates to an apparatus for producing a socket pipe from a compactable mixture, in particular concrete, in a mold with a longitudinal axis aligned in the direction of gravity and a lying in the direction of gravity sleeve molding with a compression device, on the one or more surface portions are provided, which press during the filling of the batch under the action of force on the compactable mixture, wherein the force acts with its main component respectively in the direction of erected on such a surface section normal and the normal with the direction of gravity forms an angle ⁇ .
  • Concrete and reinforced concrete pipes for pipelines are usually provided at their ends with suitable geometries to allow a tight coupling of the pipes or a coupling to other elements of a wiring harness.
  • On simple pieces of pipe to one end is designed as a sleeve with a slightly enlarged inner diameter, whereas the other end just expires or is slightly tapered on its outer wall to a so-called spigot.
  • a tube is inserted with its smooth end or its spigot end into the sleeve of the other tube. By a precise fit, a high density of the joint can be achieved.
  • Straight pipe sockets made of concrete can be produced in hollow forms aligned in the direction of gravity, upright longitudinal axis by the Concrete filled from above into the mold, spent by suitable devices to the inner wall of the mold and compacted there.
  • the use of molds with bottom sleeve molding section allows a decalcifying the sleeve tube after its compression, without having to wait for a curing of the batch.
  • the hollow mold usually comprises a cylindrical outer shell and other shaping components for forming the geometry of the pipe ends.
  • a mold ring is used with a corresponding negative contour in the outer shell.
  • the space formed between the contoured ring and the outer shell is first filled with compactable mixture. Thereafter, the further construction of the sleeve tube along the inner wall of the outer shell takes place.
  • the compactable mixture is pressed by means of suitable pressing tools against the inner wall of the outer shell.
  • suitable pressing tools for example, so-called roller heads with multiple pressure rollers are used, which press the filled mixture radially against the wall of the outer mold, thereby compressing and at the same time smooth the inner wall of the sleeve tube.
  • roller heads with multiple pressure rollers are used, which press the filled mixture radially against the wall of the outer mold, thereby compressing and at the same time smooth the inner wall of the sleeve tube.
  • the mixture between the molding ring and the jacket can not be radially compressed by a roller head or another radial pressing tool. With the conventional methods and devices an optimal material density in the socket area is not achievable.
  • Such production facilities are known for example from DE 42 109 94 A, SU 1567376 A and US 4,756,861 A and also from DE-A-111 8 630.
  • the mechanical vibrations are used only for compression of the sleeve molding section, whereas in other sections of the mold, the compaction of the batch takes place by means of radial rollers.
  • the transition region between the zone compressed by vibrations and the zone compressed by pressures in the radial direction is particularly susceptible to damage.
  • the production time for the formation of a sleeve tube lengthens in vibrational compression of the batch in the socket molding section.
  • the device described there for the spin-pressing of a concrete pipe uses a roller head with radial rollers and a pressure ring arranged above the radial rollers.
  • the pressure ring has a frusto-conical outer wall which extends along the inner wall of the outer shell and tapers in the direction of gravity.
  • the compacting effect that can be achieved with this is limited above the radial rollers due to the arrangement of the pressure ring and is insufficient with a more complicated geometry of the cavity to be filled in the socket molding section, for example when embedding a seal. If a reinforcement cage is to be embedded in the socket tube, the flow obstruction of the mixture caused by the frustoconical outer wall is insufficient to achieve greater compression in the socket molding area since the maximum outer diameter of the pressure ring is limited by the reinforcement in the area of the tube.
  • the invention is based on the object to provide a method and an apparatus of the type mentioned, in which, while avoiding additional noise emissions, a high degree of compression of the batch is achieved in the socket molding section.
  • the above object is achieved by a method of the type mentioned above, wherein the direction of the pressure exerting force K is inclined at least in the region of the sleeve molding portion against the direction of gravity or at least in the region of the sleeve molding portion is acted upon with a force on the mixture, whose main direction of action with the direction of gravity includes an angle in the range 0 ° ⁇ ⁇ 90 °.
  • the mixture to be compacted is actively pressed into the socket molding section. Due to the inclination of the direction of the pressure exerting force K complete, cavity-free filling of the sleeve portion and a particularly effective compaction is achieved. This makes it possible to produce sleeves with high dimensional accuracy and strength.
  • the pressure-exerting force K is applied in the circumferential direction of the mold circumferentially on the compactable mixture. This results in a pulsating load of the mixture, through which a further increase in the compression is achieved.
  • the inclination of the pressure-exerting surface portions relative to the direction of gravity from a first position in which the angle ⁇ 90 °, in a second position in which the angle ⁇ in the range 0 ° ⁇ ⁇ ⁇ 90 °, changeable, wherein in the first position of the surface portions, the main component of the force acting direction is aligned perpendicular to the direction of gravity and in the second position, the main component of the force acting direction is inclined against the direction of gravity and thus against the longitudinal axis of the mold.
  • the device of the invention allows in addition to the possibility of a strictly radially directed compression of the mixture, as it is known for example from conventional roller heads, additionally pressing with a downwards, ie in Direction of gravitational force or at least one force with a downward force component.
  • this allows the mixture in the socket molding section to be compacted particularly effectively. It can be achieved for the compression of the mixture in the region of the sleeve molding section and along an adjoining shaft portion with a constant inner diameter a largely uniform compression.
  • At the finished sleeve tube results in a homogeneous over the entire length structure. In particular, inhomogeneities in the transition region between the sleeve molding section and the shaft section are avoided. Since the same compression means can be used for the compression of the batch in the socket molding section and in the shank section, the socket pipe can be continuously made from the lower edge to the upper edge of the mold.
  • a mechanical gear is provided for inclining the pressure-exerting surface portions, which is particularly robust and therefore less prone to failure.
  • Rollers are preferably provided for compressing the batch, which form the pressure-exerting surface sections on their outer circumference.

This results in a particularly simple mechanism for tilting the pressure-exerting surface sections. For this purpose, only the respective axis is pivoted, whereby the respective roller is displaced in the radial direction.
  • a displacement of the same can be achieved to the outside, so that with a suitable dimensioning of the rollers in the expanding in its diameter transition region of the mold between the shaft portion thereof and the sleeve molding section a pressure on the mixture up to close can be done zoom to the inner wall of the mold. Even if a reinforcing cage is embedded in the socket tube, it is still possible to achieve a higher one Achieve degree of compaction in the socket molding section. With appropriate geometry of the socket molding section, it is also possible that the rollers at least partially submerge in this.
  • the pressure cone generated in the compactable mixture reaches all corners of the sleeve molding section, in particular the inner edge of the end face of the sleeve tube and the inner wall of the sleeve, so that they can be finished with great accuracy. This is advantageous for a high sealing effect between mutually coupled sleeve pipes.
  • the leg of the axle mounted on the support encloses an acute angle ⁇ with the longitudinal axis of the hollow pipe. Furthermore, the leg bearing the roller is bent relative to the leg mounted on the support by the same acute angle ⁇ .
  • This embodiment has the advantage that, in a rigorous radial orientation, the pressure-exerting surface portions of the rollers, i. in pure radial pressing, the above-described conveying effect is avoided, but adjusts itself to a tendency of the rollers.
  • the acute angle ⁇ 45 '.
  • rollers In principle, it is possible to rigidly connect the rollers with the legs, so that when a rotating relative movement between the compression device and the mold around the longitudinal axis, the rollers slide over the inner wall of the forming sleeve tube.
