Definitions

  • the invention relates to a device for producing concrete blocks, according to the preamble of claim 1.
  • DE 20 2013 003 472 U1 teaches the use of filling wagons which are open at the bottom and which can be moved over a mold with one or more mold nests for concrete blocks which are open at the top, for filling the mold cavities with a concrete mixture.
  • the document also suggests filling in an inexpensive core concrete first and then one or more (multi) colored facing concrete. For this purpose, the use of a special filling car is suggested.
  • the procedure in practice is such that the molding tool 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 has a linear course and runs parallel to a longitudinal axis of the device.
  • the aim is to structure the later top of the concrete blocks so that they resemble a natural product or a natural stone.
  • the object of the invention is to propose 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 are neither perpendicular nor parallel to the filling axis, but rather 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, a longitudinal direction of the surface structure running parallel to the filling axis.
  • the surface structure is formed by shaping the top of the concrete block, the device being set up to apply the surface structure during the production of the concrete blocks.
  • the longitudinal direction of the surface structure on the top / visible side of the concrete block which runs obliquely to the upright side walls of the concrete block, ensures that the concrete block looks very similar to a natural stone. In this way, the concrete block has a much more natural appearance than with a parallel or vertical course of the longitudinal direction of the Surface structure to the fill 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, wherein the device is set up to apply the color or color change parallel to the filling axis or parallel to the longitudinal direction of the surface structure.
  • the color or the color change follows the longitudinal direction of the surface structure, so that it cannot happen that the color or color change does not match the structure and can even counteract it.
  • the mold has one or more mold cavities.
  • Another special feature can be that, in the case of several mold nests, the individual mold nests are arranged at the same or one or more different angles to the filling axis.
  • a plurality of mold cavities are arranged in one or more rows and / or columns, the angles of the mold cavities to the filling axis being the same or different, in particular within a row and / or column or from row to row or column to column .
  • FIG. 1 is a plan view of a production plant for concrete blocks according to the prior art
  • FIG. 2 shows a first embodiment of a device according to the invention in plan view
  • 3 shows a concrete block produced in the device according to FIG. 2 in plan view
  • FIG. 4 shows the device according to FIG. 2 showing the surface structure of the concrete block
  • FIG. 5 shows the concrete block according to FIG. 3 with a representation of the surface structure
  • FIG. 6 shows a combination of the representations according to FIGS. 2 and 4
  • Fig. 8 shows a second embodiment of an inventive
  • FIG. 9 shows a concrete block produced in the device according to FIG. 8
  • FIG. 10 shows the device according to FIG. 7 showing the surface structure of the concrete block
  • FIG. 11 shows the concrete block according to FIG. 8 with representation of the surface structure
  • FIG. 13 shows a combination of the representations according to FIGS. 8 and 10
  • FIG. 14 shows a third exemplary embodiment of a device according to the invention in plan view
  • FIG. 16 shows the device according to FIG. 14 with illustration of the
  • FIG. 17 shows the concrete block according to FIG. 15 with a representation of the surface structure
  • FIG. 18 shows a combination of the representations according to FIGS. 14 and 16 and
  • FIGS. 15 and 17 show a combination of the representations according to FIGS. 15 and 17.
  • Fig. 1 shows a device for the production of concrete blocks, as is often used in practice.
  • a production field 11 is located on a support board 10, in the area of which a mold 12 is arranged. Walls 13, 14, 15, 16 of the mold 12 laterally delimit a mold cavity 17 of the mold.
  • Arrow 18 indicates a filling axis or filling direction in which the mold and a filling element are moved relative to one another, for example in accordance with DE 20 2013 003 472 U1 mentioned at the beginning.
  • the orientation of the walls 13 ... 16 of the mold 12 with respect to the filling axis 18 is of importance for the invention. All the walls 13 ... 16 run (taking into account the usual manufacturing tolerances) either parallel to the filling axis 18 or perpendicularly thereto. Walls 13, 14 run perpendicular to the filling axis 18 and walls 15, 16 run parallel to the filling axis 18. The axes of symmetry of the shape 12 through the middle of the walls 13 ... 16 either run parallel or perpendicular to the filling axis 18. Since the shape in the plan is square, the walls 13, 14 and 15, 16 each run parallel to one another.
  • the mold cavity 17 is filled with a concrete mixture, the mold cavity 17 and the filling device being moved relative to one another. Thereafter, further work steps can take place, such as pulling off the top of the mold 12 and compacting the filled concrete mixture, for example by shaking. After the concrete mixture has set, the concrete block 19 can be released from the mold.
  • 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 obliquely to the filling axis 18. The same applies to the symmetry axes of shape 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.
  • FIGS. 4 and 5 Another special feature is shown in FIGS. 4 and 5, namely a surface structure 20 which is formed on an upper side of the concrete block 19.
  • Surface structure 20 may be applied by stamping or by any of the other methods commonly used in the art.
  • the surface structure 20 can be designed as a structure or texture in the region of the top 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. Different colors or a color change can be used as the coloring, for example, just as with a natural stone to be imitated.
  • the surface structure 20 is formed by the shape and color of the concrete block 19. Alternatively, only one of the two methods can be used.
  • a special feature with respect to the surface structure 20 is that it extends essentially in a longitudinal direction, which is essentially parallel to the filling axis 18.
  • the longitudinal direction is indicated by parallel axes 21. Accordingly, the longitudinal direction of the surface structure 20 runs obliquely, that is to say 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 applied parallel to the filling axis and thus parallel to the longitudinal direction of the surface structure 20.
  • the second exemplary embodiment according to FIGS. 8 to 13 differs from the first exemplary embodiment in that
  • row 23 runs transversely to filling axis 18,
  • each mold 12 is arranged at a different angle 22 to the filling axis 18,
  • the angles 22 have other, different sizes, namely 8 °, 10 ° and 15 °.
  • the third exemplary embodiment according to FIGS. 14 to 19 has the following special features:
  • six molds 12 are arranged in two rows 23 of three molds 12 or in three columns 24 of two molds 12,
  • the shapes 12 are square, and
  • the angles have sizes of 10 °, 15 ° and 20 °.
  • the forms 12 are arranged obliquely to the filling axis 18, and
  • the longitudinal direction of the surface structure 20 runs parallel to the filling axis 18.
