Definitions

  • the invention relates to a method for the production of pipes from concrete batches, wherein the concrete quantity is filled into a shaping device for shaping and compacted there with a tool.
  • the invention further relates to arrangements with which the method can be carried out.
  • Vibratory processes are usually used to manufacture pipes from concrete used to compact the concrete. This is done in a vertical Intake form, the walls to shape the outer and inner contours of the Pipe has fresh concrete poured into the space between these walls, which is continuously vibrated. About the vibrations To generate, one or more vibrators are used, mostly in the interior the recording form are arranged. According to the large mass of Such a vibration system must be able to manufacture the entire pipe To set the mass of the concrete quantity and the shape of the absorption in vibration, which is associated with high energy consumption. Add to that a considerable Part of the energy is lost because it does not vibrate in the optimal way Frequency range, but in bending vibrations, causing heat and noise acoustic vibrations is converted. Such vibration methods are therefore noise and energy-intensive, which is caused by the production of concrete pipes combines these procedures with high costs and also health risks.
  • An improvement in energy consumption and uniformity of material properties can e.g. achieved with the arrangement described in WO 92/18307 be4 who also uses a vibration process and against each other there are movable inner and outer shaping elements, however actually only the inner shaping elements are moved while that outer element corresponds to a casing.
  • the vibrations are in one Vibrating head of an inner shaping element generated and on a narrow Area limited along the pipe, which in the course of the concrete supply along the Axis of the tube is shifted.
  • the upper part of the vibrating head has a helical shape and conical shape, and by rotation the batch coming from above transported downwards and due to the taper also the static pressure generated. The compression itself is then achieved through the vibration.
  • Roller head processes are also used to manufacture pipes from concrete batches used.
  • a rotating press tool compresses the concrete quantity by pressing against a casing.
  • the compression Difficulties in the area of the sockets is also used.
  • the invention is based on the object to develop a process with which concrete pipes are low noise and efficient at high Quality regarding uniformity and stability of the material properties of the pipe can be produced.
  • this object is achieved in a method as described in the introduction Art solved in that the amount of concrete in a space between two parts of a tool rotating relative to each other is compressed. there there is both the possibility that only one tool part rotates or both with different Speeds in the same direction. It is particularly effective However, procedure with counter rotation.
  • the shell shape immediately after the end of compression and Separate the shape from the tube. So the jacket shape stands directly for the next manufacturing process available.
  • the invention further includes arrangements with which the manufacturing process can be implemented.
  • Such shaping devices comprise a jacket shape to form the outer contour of the tube and a multi-part, with at least a tool connected to compress the tool into the Forming device filled concrete batch and for shaping the inner contour.
  • a first and a second part of the tool are relative to each other driven in rotation. Only one part of the tool can rotate, both parts in parallel with different speeds, or both parts in opposite directions, with same or different speeds. Between a first worktop section the first part of the tool and a second work surface section The second part of the tool has a space between Passage and compaction of the concrete batch.
  • the inner contour also has a second work surface portion of the first part of the tool the shape of a first outer cylinder with the axis of rotation of the first part of the Tool as an axis of symmetry.
  • the diameter of the first outer cylinder is selected according to the inside diameter of the pipe to be manufactured.

  • a value of about double the average diameter of the largest grains of the concrete mix proven to be particularly effective.
  • the opposite rotation of two tool parts rotating around the same axis To achieve, it is useful to separate both parts of the tool To drive waves.
  • the first part of the tool is preferred via a Shaft and the second part of the tool via a hollow shaft surrounding the shaft driven.
  • This has the advantage that both parts have a common drive device can be driven, or via two drive devices, the adjacent along the axis of rotation to save space and easily accessible are attached.
  • two shafts with two drive devices are also conceivable on opposite sides of the tool.
  • the tool and the casing shape are mutually opposed slidably mounted.
  • a guide for the tool provided to achieve a relative movement.
  • the jacket shape rigidly fixed and the tool by means of the guide with concrete supply be moved from one end of the mold to the other.
  • the tool can be relative to the shell shape along the axis of rotation be moved until the other end is reached and removed there.
  • compression and shaping i.e. high uniformity of the Material properties
  • Another conceivable variant would also be the fixation of the tool and a moving mounting shape.
  • the manufacture of continuous tubes is also included.
  • the two work surface sections are advantageous in such a shaping device of the two tool parts, between which there is the space for the passage and compaction of the concrete mix, conical shape, the axis of symmetry of a cone with the axis of rotation of the respective tool part and the axis of symmetry of the tube coincides. In doing so you will each not choose a full cone as the work surface section, but only one segment at a time, which corresponds to a cut perpendicular to the axis of symmetry, because in this way there are other worktop sections with different functionality remain available. Due to the conical shape, the space has now via an opening that is oriented to the axis of rotation and another Opening in the direction of the outer area between the tool and the shell shape is oriented, which simplifies the control of the concrete batch flow.
  • the first work surface section has the first Part of the tool on the shape of a first outer cone, which is in the Direction from which the concrete quantity is fed is tapered.

  • this cone angle of this cone is advantageously equal to that or less than the cone angle of the first outer cone: Has this cone the same cone angle as the first outer cone, so the material is through passed the space and essentially only by rolling on each other compacted. However, this cone has a slightly smaller cone angle than that first outer cone, preferably 60 °, the circular sections fall to the blunt end of the first outer cone flatter, which increases the compression and also builds up a greater pressure than the same cone angle with which the batch finally from the space in the area between the shell shape and the tool is pressed.
  • a second work surface section has the second part of the tool in the form of a second outer cone on whose axis of symmetry is the axis of rotation of the second part of the Tool corresponds, and which is fed in the direction from the concrete batch is rejuvenated.
  • the available area between tool and shell shape is smaller.
  • the compacted amount of concrete swells through the opening through which it flows out exits the space, also upwards, as it exits under pressure. Due to the conical shape of the second worktop section of the second part of the tool is therefore the action of stronger forces on the tool congestion of concrete during shaping in the area of the tip end shape avoided. This works particularly effectively in the area of cone angles between 65 ° and 83 °, preferably at a cone angle of 77 °.
  • the spiral depression advantageously has Cross-section along the axis of rotation the contours of circular sections, with the contour-defining circles in the simplest, easiest to implement Variant all have the same radius.
  • the spiral is expedient Depression on the second outer cone designed so that the center points of the circles that determine their contours lie on a cone. It is for one Even transport of the already compacted mixture is advantageous if the cone angle of this cone is the same or one - with a difference of an amount of up to about 5 degrees - a cone angle similar to the second outer cone, preferably 78 °.
