Definitions

  • the invention relates to a device for producing concrete blocks, according to the preamble of claim 1.
  • the invention also relates to a corresponding method for producing concrete blocks, according to the preamble of claim 11.
  • the procedure in practice is such that the mold and the filling carriage are moved relative to one another, namely in a filling axis or filling direction.
  • the filling axis or filling direction generally follows a linear course and runs parallel to a longitudinal axis of the device.
  • the invention is based on the object of proposing measures to improve the production of concrete blocks.
  • a device according to the invention has the features of claim 1.
  • the filling axis is aligned obliquely to an axis of symmetry of the at least one mold cavity, so that preferably all walls of the mold cavity run neither perpendicularly nor parallel to the filling axis, but at an angle.
  • the or each mold cavity is rectangular in plan and has four walls that run obliquely to the filling axis.
  • the angle between the filling axis and the axis of symmetry is at least 5°, preferably between 5° and 30°, in particular between 5° and 20°.
  • the device is set up to provide the concrete blocks with a surface structure, with a longitudinal direction of the surface structure running parallel to the filling axis.
  • the surface structure is formed by shaping the upper side of the concrete block, with the device being set up to apply the surface structure during production of the concrete block.
  • the longitudinal direction of the surface structure on the upper side/visible side of the concrete block which runs obliquely to the upright side walls of the concrete block, means that the concrete block looks very similar to natural stone. In this way, a significantly more natural appearance of the concrete block is achieved than with a parallel or perpendicular course of the longitudinal direction of the surface structure to the filling axis. In such cases, the concrete blocks can appear unnatural, which is avoided with the solution according to the invention.
  • the device is set up to provide the concrete blocks with a color or a color change, the device being set up to apply the color or the color change parallel to the filling axis or parallel to the longitudinal direction of the surface structure.
  • the hue or the color change follows the longitudinal direction of the surface structure, so that the hue or color change does not match the rest of the structure and can even counteract it.
  • the mold has one or more mold cavities.
  • Another special feature can be that when there are several mold cavities, the individual mold cavities are arranged at the same angle or at one or more different angles to the filling axis.
  • a corresponding method has the features of claim 11. Accordingly, it is provided that the filling axis is aligned obliquely to an axis of symmetry of the at least one mold cavity, so that preferably all walls of the mold cavity run neither perpendicularly nor parallel to the filling axis, but at an angle.
  • the or each mold cavity is rectangular in plan and has four walls that run obliquely to the filling axis.
  • the surface structure is formed by shaping an upper side of the concrete block, the surface structure being applied during production of the concrete blocks.
  • the concrete blocks are provided with a color or a color change, the color or the color change being applied parallel to the filling axis or parallel to the longitudinal direction of the surface structure.
  • FIG. 1 shows a device for the production of concrete blocks, as is often used in practice.
  • a base board 10 there is a production field 11, in the area of which a mold 12 is arranged.
  • Walls 13, 14, 15, 16 of the mold 12 delimit a mold cavity 17 of the mold laterally.
  • Arrow 18 indicates a filling axis or filling direction in which the mold and a filling member are moved relative to one another, for example in accordance with the one mentioned at the outset DE 20 2013 003 472 U1 .
  • the orientation of the walls 13 ... 16 of the mold 12 in relation to the filling axis 18 is of importance for the invention. All walls 13 ... 16 run (taking into account the usual manufacturing tolerances) either parallel to the filling axis 18 or perpendicular thereto. Walls 13, 14 run perpendicular to the filling axis 18 and walls 15, 16 run parallel to the filling axis 18. The symmetry axes of the mold 12 through the centers of the walls 13 ... 16 also run either parallel or perpendicular to the filling axis 18. Since the shape in plan is square, the walls 13, 14 and 15, 16 are parallel to each other.
  • the mold cavity 17 is filled with a concrete mixture, with the mold cavity 17 and the filling device being moved relative to one another. Thereafter, further work steps can take place, such as stripping the upper side of the mold 12 and compacting the concrete mixture that has been filled in, for example by shaking. After the concrete mixture has set, the concrete block 19 can be released from the mold.
  • Figures 2 to 7 show a first embodiment of the invention.
  • a special feature is that the walls 13 . . . 16 of the square shape 12 run or are arranged at an angle to the filling axis 18 . The same applies to the axes of symmetry of the mold 12 running through the centers of the walls 13 ... 16.
  • the angle 22 between the filling axis 18 and the walls 15, 16 is 25°.
  • the angle 22 can also have other sizes.
  • FIG. 4 and 5 Another special feature is in Figures 4 and 5 shown, namely a surface structure 20 which is formed on a top side of the concrete block 19.
  • the surface structure 20 can be applied by embossing with a stamp or by any of the other methods customary in the art.
  • the surface structure 20 can be designed as a structure or texture in the area of the upper side of the concrete block, and in particular can be modeled on a corresponding structure or texture of a natural stone.
  • the surface structure 20 can be supplemented or supported by a corresponding coloring in the area of the upper side. Come as coloring different shades or a color change in question, for example as well as with a natural stone to be imitated.
  • the surface structure 20 can be formed by the shaping and coloring of the concrete block 19 .
  • only one of the two methods can be used.
  • a special feature of the surface structure 20 is that it extends essentially in a longitudinal direction, which runs essentially parallel to the filling axis 18 .
  • the longitudinal direction is indicated by parallel axes 21 in the drawings. Accordingly, the longitudinal direction of the surface structure 20 runs obliquely, i.e. neither parallel nor perpendicular to the walls 13 ... 16 of the mold 12 or to the side walls of the concrete block 19.
  • the coloring or color change is parallel to the filling axis and thus parallel to the longitudinal direction of the surface structure 20 applied.
