Definitions
- the present invention relates to concrete slabs and concrete blocks, as well as a Process for their production ..
- the object of the present invention is a concrete slab or a Concrete block, with a face that can be created in at least two differently designed zones is divided.
- this object is achieved by a method Claim 1, or a stone or a plate according to claim 14 solved.
- a form is used in the method according to the invention, which has a bottom plate, the surface of which can be partially lifted Plate segment is formed.
- This plate segment becomes relative to the remaining surface of the base plate raised so that the base plate a has a graduated surface.
- the surface of the bottom plate which is deeper than the surface of the raised plate segment is now with a Layer of a first concrete covered.
- the second concrete differs from the first concrete by at least distinguishes a supplement or an additive. So can be the first and second concrete e.g. by an added dye and / or by a differentiate the added granules.
- first Zone formed by the first concrete and the shape of the originally has a lower surface of the base plate, and one second zone formed by the second concrete and the shape of the originally raised plate segment.
- the second concrete forms in the finished stone or in the finished slab a basic body, so to speak, in the surface of which a motif insert is embedded in the first concrete, which is sharply contoured, i.e. without flowing away the Boundary, separated from the basic body. It is particularly important to emphasize that when the stone or slab hardens, the grain scaffolds in the Motif insert and the base body at their interfaces by a uniformly hardened cement stone are cemented together so that a there is an optimal bond between the base body and the motif insert.
- the method according to the invention therefore makes it possible in a simple manner Concrete blocks and concrete slabs that have a surface with a have permanent motif inlay, which is from the surface of the Basic body etc. through a different color scheme and / or Can distinguish surface structure.
- the finished stone or slab also has a flat surface on.
- the motif insert protrude from the basic body, or the To design a motif insert as a recess in the base body. For this, in End position of the plate segment after lowering, the surface of the Plate segments higher or lower than the remaining surface of the base plate lie.
- the plate segment is advantageously raised hydraulically or pneumatic, with a hydraulic when lowering the plate segment or pneumatic pressure is reduced in a controlled manner using a throttle valve.
- the lowering speed of the plate segment important for the contour sharpness can thus be controlled with simple means.
- the contour sharpness can also be improved in that the Shaking or vibrating the mold when lowering the first plate segment mainly includes vertical movements.
- the actual pressing process preferably takes place during the Lowering of the plate segment instead.
- the level difference between the surface of the plate segment and the surface of the rest Base plate should preferably be between 5 and 15 mm. Larger Differences in level than 15 mm are of course also possible. she however, require that larger amounts of the second concrete when lowering the Disk segments must be redistributed. However, they hardly bring Advantages, since a layer thickness of only 5-10 mm is sufficient Guaranteed durability for the motif insert.
- the concrete is advantageously entered into the mold as follows. To Lifting the slab segment, the first concrete is on the floor slab abandoned and then level with the surface of the raised Strip segments stripped. After stripping is then a Form frame placed around the base plate, or by an additional side part completed. Then the second concrete is poured into the mold.
- FIG 1 is a form 10 for the inventive method on a Vibrating table 11 shown.
- the mold 10 comprises a base plate soft overall is designated by the reference numeral 12 and a molding space 14 downwards limited.
- the mold space 14 is delimited laterally by a mold frame 15.
- a part of the base plate 12 is designed as a plate segment 16 which relative to the rest of the base plate by means of pneumatic or hydraulic Printing cylinder 18, 20 can be raised in the mold space 14.
- the plate segment 16 is shown in the raised state.
- the bottom plate 12 has a stepped surface, on the one hand by a Form space 14 facing surface 20 of the raised plate segment 16 and on the other hand by a surface 22 facing the molding space 14 a motif insert 24 is formed.
- the bottom plate 12 has a recess 26, the bottom surface of which the surface 22 of the Motif insert 24 and its side surfaces by side edges 26, 28, 30th of the raised plate segment 16 are formed. Note that the side edges 26, 28, 30 of the raised plate segment 16, the Partially cover the side edges of the motif insert 24 laterally.
- the Level difference between the surface 20 of the raised Plate segment 16 and the surface 22 of the motif insert 24 is preferably between 5 and 15 mm.
- first concrete 32 on the motif insert 22.
- a mixture of a binder and at least one Surcharge usually, a damp concrete comes from cement and one mineral surcharge used.
- the concrete can also contain a dye or contain granules as an additive.
- this will be the first Concrete 32 level with surface 20 of the raised slab segment 16 stripped.
- Figure 2 shows the stripped layer of the first concrete 32 in the Indentation 25 of the base plate 12.
- the mold frame 15 is preferably only after denying the Base plate 12 lowered, or closed after denial.
- the vibrating table 11 can be actuated briefly before stripping to evenly distribute the first concrete in the recess 25 and easy to pre-compact.
- the molding space 14 is then covered with a second concrete 34 replenished.
- the first and second concrete differ in this at least one supplement or additive, so that they in the cured form visually different surfaces.
- the second layer of concrete 34 covers the surface 20 of the Slab segment 16, as well as the existing layer of the first concrete 32.
- FIG. 3 shows the mold 10 filled with the second concrete 34. Before a press ram 36 is inserted into the mold 10, one more time The vibrating table 11 can be operated briefly in order to evenly pass the second concrete 34 Distribute molding space 14.
- the raised plate segment 16 is now, preferably under constant shaking or vibrating in the vertical direction of the mold 10, slowly lowered.
- the proportion of the second follows Concrete 34 which rests on the slab segment 16 and this lowering movement lies seamlessly on the progressively released edge of the first concrete 32 on. There is no mixing of the harvested and second concrete on the Interface instead.
- the lowering of the plate segment 16 is advantageously carried out by a pneumatic throttle valve (not shown) controlled with the pneumatic pressure cylinders 18, 20 is connected. During lowering the plate segment 16, the stamp 36 exerts a pressure.
- FIG 5 shows the shape 10 after the lowering of the Plate segments 16 shown.
- the surface 20 of the plate segment 16 and the surface 22 of the motif insert 24 are in one in this end position Level.
- the punch 36 now also compresses the two concrete 34 and 32 increased pressure to achieve the necessary strength of the stone.
- the pressed stone can then be removed from the mold and Harden.
- FIG 6 is a top view of the surface of the finished stone shown, which rested on the base plate 12 of the mold 10.
- Motif insert 40 which is formed by the first concrete 32
- base body 42 formed by the second concrete 34 becomes.
- the transition at the interfaces between motif insert 40 and Base body 42 is extremely contour-sharp. If you cut the stone by, it is also found that the motif insert 40 and the base body 42 Have grain skeletons, which at their interfaces by a uniform hardened cement stone to be cemented together. The latter ensures that an optimal bond between the base body 42 and the relatively thin motif insert 40 is present.
- the method according to the invention can be extremely complex Motif deposits, almost without additional work during the Press process, permanently embed in a concrete block or a concrete slab.
- Such motif inserts can not only be simple with great contour sharpness Pattern but e.g. also company logos, letters, numbers, symbols represent.
- the motif inlays can also be designed such that a certain symbol composed by several stones or slabs becomes.
