Definitions
- the invention relates to a method for producing shaped stones according to the preamble of claim 1.
- the invention further relates to a device, in particular a mold for producing shaped stones according to the preamble of claim 8 and a row of shaped stones according to the preamble of claim 12.
- the invention relates in particular to the production of so-called pile wall stones.
- several shaped stones are produced in a single mold and separated from each other in the area of predetermined breaking points after demolding.
- the shaped stones are usually separated by hand using suitable tools.
- side surfaces of the shaped stones have a fractured surface which forms a visible surface after the shaped stones have been laid.
- a disadvantage of known methods is the high expenditure of time and effort required to separate the shaped blocks.
- the object of the invention is to propose measures such as a method, a mold and a row of shaped blocks, with which shaped blocks can be formed in a simple and reliable manner by separating the row of shaped blocks.
- the method according to the invention has the measures of claim 1. These measures make it surprisingly easy to separate the individual stones of a row of stones from one another. Due to the lateral pressure, the row of shaped blocks is exposed to corresponding forces, which lead to the breaking of the row of shaped blocks in the area of the predetermined breaking points and thus the separation of the shaped blocks.
- the axes and in particular the side surfaces of the shaped stones have directions which differ from one another in the longitudinal direction of the respective shaped stone row, in particular such that they have an approximately zigzag course.
- the longitudinal axes of adjacent shaped stones can run obliquely or at an angle to one another.
- the row of molded blocks is subjected to tensile forces with comparatively low pressure, which lead to the separation of the molded blocks from one another, namely in the area of the predetermined breaking points.
- some shaped stones have axes parallel to each other and some shaped stones have obliquely directed axes.
- several rows of molded blocks for separating the predetermined breaking points are arranged in such a way that the rows of molded blocks only abut one another in regions, in particular in the area of predetermined breaking points, and that the respective outer rows of molded blocks are moved towards one another.
- the lateral pressure on the rows of blocks pushes them against each other.
- the respective outer rows of shaped blocks are preferably moved towards one another.
- a device according to claim 8 is used to achieve the above-mentioned object.
- This device is preferably suitable for use in the method according to the invention.
- the shaped stones or rows of shaped stones produced in this device can be easily and reliably separated from one another, in particular by machine, after production using the method according to the invention.
- a row of shaped stones used to solve the task has the features of claim 12. Such rows of shaped stones can be separated particularly easily in the method according to the invention for forming individual shaped stones described above. Each row of shaped stones preferably has at least two shaped stones.
- shaped stones of shorter length are arranged on at least one free end of a row of shaped stones.
- the end stones are also connected to an adjacent shaped stone in the area of a predetermined breaking point, so that when the row of shaped stones is separated, each shaped stone (with the exception of the end stones) has two visible surfaces with a broken structure.
- FIG. 1 is an enlarged view of a portion of FIG. 1,
- Fig. 3 a schematic representation of a row of shaped stones in enlarged
- Fig. 4 a schematic representation of a device for the production of
- Shaped stones in vertical section are Shaped stones in vertical section.
- FIG. 1 to 4 relates to the manufacture of so-called pile wall stones.
- Such stones are used for example for the production of partially green retaining walls or the like. Since the stones are not exclusively limited to the use in connection with pile walls, the general term shaped stone 10 is used below to represent other types of stones.
- the shaped block 10 shown consists of a basic body 11 which is essentially rectangular in plan with upright side surfaces 12, 13, 14, 15 and horizontally oriented upper side 16 and lower side 17.
- two projections 18 which are trapezoidal in plan are arranged.
- the opposite side surface 15 has four corresponding recesses 19 which are also trapezoidal in plan.
- the projections 18 and recesses 19 serve for the horizontal and / or vertical interlocking of the shaped stones 10 with one another.
- the projections 18 of a molded block 10 step into recesses 19 of an adjacent molded block 10.
- the shaped blocks 10 are produced in a device with essentially known parts according to FIG. 4.
- a mold frame 20 of a mold 37 which is open at the top and bottom, rests on a base board 21.
- the mold frame 20 has a plurality of mold nests 22 which are delimited by upright mold walls 23 of the mold frame 20 become. Concrete is poured into the mold nests 22 from above and compacted by shaking.
- the underlay board 21 can rest on a vibrating table 24.
- a stamp 25 is lowered into the mold nests 22 from above.
- An underside of the stamp 25 is also profiled to form constrictions 29 in the area of the top 16 of the shaped blocks 10.
- a drawing plate 26 is arranged between the shaped frame 20 and the underlay board 21.
- the drawing plate 26 has webs 27 projecting upwards on its upper side. To form the constrictions 29, the drawing plate is pulled away laterally under the molding frame 20, the webs 27 forming the constrictions 29.
- a special feature of the device shown in FIG. 4 is the arrangement of the mold cavities 22 in the mold frame 20.
- the mold cavities 22 are arranged in a row in the mold frame 20.
- adjacent mold cavities 22 are connected to one another in the region of the side surfaces 12, 14, so that a plurality of molded blocks 10 in a row are produced in a continuous manner as a molded block row 28.
- Fig. 1 shows three rows of molded blocks made in such a shape in the plan.
- the mold nests 22 are further designed such that the rows of molded blocks 28 have constrictions 29 in the transition from the side surfaces 13, 15 to the side surfaces 12, 14 of adjacent molded blocks 10. Further constrictions 29 are arranged between the upper sides 16 and lower sides 17 of adjacent shaped stones 10.
- the constrictions 29 reduce the cross-sectional area of the row of shaped stones 28 and thus predetermined breaking points 30 are formed between the adjacent shaped stones 10 of a row of shaped stones 28.
- the predetermined breaking points 30 each run between two constrictions 29 which lie opposite one another on the side surfaces 13, 15 or top side 16 and bottom side 17.
- the constrictions 29 between the upper sides 16 and lower sides 17 of adjacent shaped stones 10 are formed on the one hand by a corresponding profiling of the punch 25 and on the other hand by the webs 27 on the drawing plate 26 (FIG. 4).
- the constrictions 29 can have a triangular or notch-like cross section, as shown.
- the constrictions 29 are accordingly arranged all around the cross-sectional area of the shaped blocks 10.
- An essential peculiarity of the invention is that the mold nests 22 or the shaped stones 10 of a row of shaped stones 28 are arranged in different relative positions to one another.
- Each shaped stone 10 has an imaginary axis 31 in the longitudinal direction of the shaped stone row 28.
- the axis 31 runs in the plan parallel to the opposite side surfaces 13, 15 in the middle of the shaped stones 10. In the case of antiparallel side surfaces 13, 15, the axis 31 runs in the plan as a bisector between the two side surfaces 13, 15.
- the mold nests 22 or the shaped stones 10 of a shaped stone row 28 are aligned such that their axis 31 runs differently to the longitudinal direction of the shaped stone row 28.
- the angle 33 between the axes 31 of adjacent shaped blocks 10 can be, for example, between 179 ° and 140 °, in particular between 179 ° and 170 °. In the exemplary embodiment shown, the angle 33 is approximately 177 °.
- the axes 31 of adjacent shaped stones 10 within a shaped stone row 28 run antiparallel.
- the axis 31 of each second shaped stone 10 of a shaped stone row runs at the same angle 33 in the same direction, so that the shaped stone row 28 has an approximately zigzag shape or contour in the area of the side surfaces 13, 15 of the shaped stones 10.
- the shaped blocks 10 are not exactly rectangular in plan, but rather approximately parallelogram-shaped.
- a plurality of rows of shaped blocks 28 are preferably produced in one working step in a molding frame 20.
- the arrangement of the mold nests 22 of a row of molded blocks 28 differs from the arrangement of the mold nests 22 of an adjacent row of molded blocks 28, so that the rows of molded blocks have an at least partially different course in the region of the side surfaces 13, 15 in the longitudinal direction thereof.
- FIG. 2 shows a section 38 according to FIG. 1 of three rows of molded blocks 28 lying next to one another with a different course.
- the side surfaces 13 of a shaped block 10 run to adjacent side surfaces 15 a further shaped block 10 at an angle 34 of, for example, 1.4 °, so that these side surfaces 13, 15 have a maximum distance 35 of 5.5 mm.
- FIG. 1 shows a section 38 according to FIG. 1 of three rows of molded blocks 28 lying next to one another with a different course.
- the side surfaces 13 of a shaped block 10 run to adjacent side surfaces 15 a further shaped block 10 at an angle 34 of, for
- the rows of shaped blocks 28 are designed and arranged in such a way that they each run in opposite directions to the adjacent row of shaped blocks 28.
- the mold frame 20 is immediately pulled upwards from the mold stone rows 28 so that they lie freely on the underlay board 21, as shown in FIGS. 1 and 3.
- the mold frame 20 can also be pulled off after the concrete has at least partially set.
- the rows of shaped blocks 28 are removed from the underlay board 21.
- the rows of molded blocks 28 are gripped along the outer side surfaces 13, 15 of the outer rows of molded blocks 28, for example by mechanical gripping members.
- the rows of shaped blocks 28 are gripped, they are pressed laterally against one another — transversely to the longitudinal direction of the rows of shaped blocks 28, whereby these differ only partially against one another due to the different course in the longitudinal direction.
- the rows of shaped blocks 28 are preferably designed such that they abut one another only in the region of a few predetermined breaking points 30, in particular in the region of every second predetermined breaking point 30, as in the exemplary embodiment shown.
- the rows of shaped blocks 28 When grasping, the rows of shaped blocks 28 are thus subjected to bending transversely to their longitudinal direction. With a correspondingly high lateral pressure, the rows of molded blocks 29 break in the area of the predetermined breaking points 28, so that the molded blocks 10 of the rows of molded blocks 28 are separated from one another. This results in a broken surface in the area of the side surfaces 12, 14 of the shaped stones 10, which is pronounced of a natural stone.
- the shaped blocks 10 can be arranged during the later laying in such a way that the side surfaces 12, 14 are positioned in the region of a visible surface, for example a wall or soil cover.
- the number of shaped stones 10 which can be produced in one working step in a molding frame 20 is essentially only limited by the dimensions of known devices for producing shaped stones 10.
- the length of a row of shaped blocks 28 is approximately 1.10 m.
- a row of blocks 28 includes four shaped stones 10 each, and two end stones 36.
- the end stones 36 are each arranged at a free end of the shaped stone row 28 and have a shorter length than the shaped stones 10, for example 80 mm. Due to the arrangement of the end stones 36, the two outer shaped stones 10 of a shaped stone row 28 in the region of both side surfaces 12, 14 also have a broken surface after the separation. Insofar as the formation of the broken surface is not important, the end stones 36 can also be dispensed with.
- a row of shaped stones 28 can also consist of only two shaped stones 10, in which case the end stones 36 are also dispensed with, so that two shaped stones 10, each with a single broken visible surface, can be obtained from one row of shaped stones 28.
- a plurality of rows of shaped blocks 28 can be produced in one working step in a shaped frame 20, the rows of shaped blocks 28 in the region of the side surfaces 13, 15 having a different course in the longitudinal direction thereof, so that when the predetermined breaking points 30 are separated they only abut one another in regions ,
- the shaped blocks 10 can be separated directly after the demoulding.
- several rows of shaped stones 28 can also be placed next to one another after demoulding, for example at the processing site, ie the construction site. It is conceivable that different shaped frames 20 are used so that the rows of shaped blocks 28 have a different course.
- the procedure is preferably such that the rows of molded blocks 28 are produced in identical mold frames 20 and that the rows of molded blocks 28 are laid next to one another alternately with the top 16 or underside 17 facing upwards, or that the rows of molded blocks 28 are rotated 180 ° relative to one another Relative position are arranged. It is also conceivable for the rows of shaped blocks 28 to be laid next to one another, with the upper side 16 facing upward, but the rows of shaped blocks 28 are arranged laterally offset from one another. In this way it is ensured that the rows of shaped stones 28 for separating the predetermined breaking points 30 between the shaped stones 10 only abut one another in regions in the region of the side surfaces 13, 15.
- the axes 31 of the shaped blocks 10 run parallel to and at a distance from the longitudinal axis 32.
- the axes 31 of adjacent shaped stones 10 of the respective shaped stone row 28 each have a different distance from the longitudinal axis 32, preferably they lie on another side of the longitudinal axis 32.
- axes 31 of some shaped stones 10 of a shaped stone row 28 parallel to the longitudinal axis 32 are aligned and some axes 31 of other shaped stones 10 of a shaped stone row 28 extend obliquely to the longitudinal axis 32.
- only one row of molded blocks 28 can be produced in a molded frame 20.
- the shaped stones 10 of this shaped stone row 28 are separated by pressure on opposite sides of the individual shaped stone row 28. This can also be done on site at the construction site.
- shaped blocks 10 can be produced in this way for any other purpose.
- the arrangement and alignment of the mold nests 22 described can also be used independently of the shape of the shaped blocks 10.
