It is provided that the rough concrete is filled into a mold and compacted by shaking and / or pressing in the mold. This lowers the coarse concrete.
- a storage container which is also referred to as header tank or header silo
- a multicolored facing layer for example when a marbled facing layer or a color mix is to be achieved, concrete or mortar masses are introduced into the storage container separately by color and mixed or unmixed into the molds.
- the described methods and devices share the disadvantage of a large mechanical and manufacturing expense.
- the cladding layers obtained by unfavorable mixing for example, as a result of heap formations, often undefined color patterns.
- a storage container which forms a receiving space for a plurality of layers of different colored concrete, wherein the bottom of the storage space is designed as a slide.
- the downstream dispensing device may have a closure member, which is designed to control a quantitative, portionwise dispensing of the colored concrete or concrete mortar and filled the molds.
- the design of the storage container with a slide causes only a relatively low mechanical complexity and leads to an improved mixing of the layers of ver. different colored concrete. Nevertheless, the mixing of layers of different colored concrete is still not cheap enough; In particular, heaps continue to occur. This is especially true for the first subset, which falls down when opening the slider. In this only a small or insufficient mixing takes place.
- EP 1 017 554 B1 proposes that the slide known from practice be combined with impact bodies which are arranged in the path of movement of the sections of the concrete layers moving downwards by gravity.
- the subsections of the concrete layers are intended to impinge on the impact bodies in such a way that the subsections are guided onto a deflection arc and are better mixed with one another.
- the present invention is therefore an object of the invention to provide an apparatus and a method for producing concrete blocks, which allow it with little effort, several Mix layers of different colored concrete in the desired manner with each other, in particular to produce facing layers with a defined, similar appearance for concrete blocks.

- the slider 14 in this case has a triangular-like incision, which in the closed state of the slider 14 is closed by a prismatic or cone-shaped, also upwardly extending projection 35. Due to the conical projection 35 more material from upper layers 10,11,12 and 13 slips when opening the slider 14 (due to the rising slope of the conical projection 35) as would be the case with a conventional slider 14. This can be advantageous for certain applications. Independently of the solution according to the invention, it is also possible for certain applications to use a slide according to FIG. 9, for example also in the device according to EP 1 017 554 B1.
- the side wall 17 provided with the dispensing openings 18 is formed as an inner wall in the receiving space 8.
- the side wall 17 is designed conical and tapers from the bottom 14 of the receiving space 8 upwards.
- a kind of slotted guide 23 is provided, which has bar-shaped dispensing means 19 and passage openings 24.
- the link element 23 is adapted to the side wall 17 and therefore also designed conical or substantially conical.
- the opening of the bottom or of the slide 14 can take place in a known manner, wherein the conical inner or side wall 17 can be connected according to FIG. 10, for example via a support frame on outer side walls of the receiving space 8.
- a further advantageous detail in particular for the embodiments illustrated in FIGS. 1 to 8, is an extension plate 36, which can be seen for example in FIGS. 2, 5 and 6.
- a bearing 37 is provided around which the wall 17b of the side wall 17 is rotatable to incline the side wall 17. Since the axis of rotation 37 in the embodiment, when the wall 17b is associated, the distance between the underside of the wall 17a and the slider 14 changes during rotation or pivoting about the axis of rotation 37, so that it may be feared that concrete 6 penetrates through the resulting gap.
- the extension plate 36 is provided, which can be extended or retracted via an operating element 38 (shown in FIG. 2) on the underside of the wall 17b, if necessary, in order to compensate for a gap created by the pivoting.
- the axis of rotation 37 may also be associated with the wall 17a.
- FIGS. 1, 2, 5 and 6 The basic principle of the device according to the invention and of the method according to the invention results from a combination of FIGS. 1, 2, 5 and 6.
- the colored concrete from the storage container 7 in FIG the mold 4 is introduced.
- the attachment layer is formed by the differently colored layers 9, 10, 11, 12 and 13.
- the layers are stored stacked in the storage container 7 and can be introduced there in any manner, preferably using the baffle 31.
- Fig. 5 at least a first subset of the layers 9,10,11,12 and 13 is discharged from the reservoir 7 by opening the discharge ports 18 in the side wall 17.
- a first subset of the layers 9,10,11,12 and 13 drops well mixed on the closure member 16 of the dispensing unit 15.
- a first subset has been well mixed with the closure member 16 is fed, can by clocking opening and closing of the discharge openings 18 through the Output means 19, the process can be repeated.
- the slider 14, as shown in Fig. 6, preferably be opened continuously or stepwise, so that portions of the layers 9,10,11,12 and 13 cancel and fall down.
- the method and the device in solid bodies of any kind and shape formed entirely of colored concrete materials. Furthermore, it may also be provided to dispense not only a subset but the entire contents of the receiving space 8 through the dispensing openings 18.
- the dispensing means 18 for opening and closing can also be dispensed with or the dispensing means 19 can keep the passage size of the dispensing openings constant. This also improves compared to the prior art, the mixing. However, it does not provide such a favorable result as if the dispensing means provide for opening and closing the dispensing openings. However, this variant should also be included in the invention.
