Definitions
- the invention relates to a method for the mechanical processing of concrete blocks by irregular removal of fragments in the area of edges and corners. Furthermore, the invention relates to a device for performing the method.
- Concrete blocks in particular concrete paving stones, are often subjected to mechanical treatment in which the edges and corners of the concrete blocks are chipped off irregularly. This should give the concrete blocks the external appearance of an (artificially) aged stone.
- the previously used method for the artificial aging of concrete blocks consists in moving the finished, set and completely hardened concrete blocks through a rotating drum. Corners and edges are chipped off irregularly within the drum, namely by mutual mechanical processing of the stones, but also by hitting the drum wall (so-called drumming of concrete blocks).
- the invention has for its object to improve the method and apparatus for mechanical processing of the paving stones, in that with less noise and dust nuisance processable units made of concrete blocks are available.
- the method according to the invention is characterized in that a group of concrete blocks
- Stone group - is positioned on a base so that the upper edges and corners are at least temporarily exposed or offset from neighboring concrete blocks and that processing bodies are moved over the group of concrete blocks arranged in this way for mechanical processing of the protruding edges and corners.
- the concrete blocks are at rest during processing, but in such a relative position to one another that edges and corners are exposed as upward projections, so that processing bodies moved over the top of the stone group can erode the relevant edges and corners irregularly.
- the stone group is preferably positioned on an inclined plane, the processing bodies being moved under their own weight in a rolling or sliding manner over the scale-like offset concrete blocks.
- the base for the stone group in particular a processing table, is movable, so that the concrete blocks can be positioned in various relative positions in a scale-like manner for processing all edges in the area of an upper side of the concrete blocks.
- the stone group treated in this way consists of concrete blocks which are positioned in a relative position required as paving stones for storage and / or transport and / or mechanical laying.
- a stone group can thus consist of a transport and laying unit or of several units positioned next to each other.
- the mechanical processing of the concrete blocks is integrated in the manufacturing process of the same. After setting in the area of drying chambers, the concrete blocks are fed directly to the mechanical processing device according to the invention. A interim storage is no longer necessary for complete hardening.
- FIG. 2 shows the device according to FIG. 1 in a side view or in a cross section in an inclined position
- FIG. 3 shows the device according to FIGS. 1 and 2 in a different position
- FIG. 4 shows a detail of the device according to FIG. 2 on an enlarged scale
- FIG. 5 shows a detail of FIG. 3, also on an enlarged scale
- Fig. 6 is a manufacturing plant for concrete blocks with equipment for mechanical processing in schematic cal plan.
- concrete blocks 10 are cuboid shaped concrete sections that are to be used as paving stones, i.e. to form a soil cover.
- the concrete blocks 10 can have any shape for the treatment, ie can also be provided with projections and depressions in order to achieve a horizontal or vertical bond.
- the concrete blocks 10 are machined in such a way that an artificial, apparent aging is generated.
- the edges and corners of the concrete blocks 10 are primarily treated by irregularly chopping off material (concrete). This processing is carried out so that all concrete stones are designed differently, that is, they do not match the fracture points.
- a special feature is that in the treatment method shown, the concrete blocks 10 are machined only in the area of an upper side. So there are only upper transverse edges 11 and longitudinal edges 12 provided by mechanical organs with irregular material removal. In the case of a pavement made of concrete blocks 10 treated in this way, these transverse edges 11 and longitudinal edges 12 provided with fractures are also located on the (visible) upper side of the pavement. The lower areas and edges of the concrete blocks 10 lying in the ground therefore remain untreated, so that spacers attached to upright side surfaces, for example, are not impaired.
- the concrete blocks 10 For the treatment of the concrete blocks 10, these are positioned on a base, in a formation that corresponds to the arrangement of the concrete blocks 10 in the area of the pavement.
- This arrangement of the concrete blocks 10 expediently also corresponds to that in a stack of concrete blocks 10.
- the concrete blocks 10 for the production of paving slabs are usually stacked in layers on pallets.
- the arrangement of the concrete blocks 10 within a layer corresponds to that during mechanical processing.
- One layer of a stack of concrete blocks 10 is expediently a laying unit, that is to say a group of concrete blocks 10, which is installed mechanically as a unit with a device.
- the concrete blocks 10 are arranged on a processing table 13.
- This is equipped with a table top 14 as a support for a group of concrete blocks 10, namely for a stone group 15.
- the table top 14 is an essentially flat supporting element with an all-round edging 16 for the concrete blocks 10 or the stone group 15.
- the table top 14 or the bearing surface defined by the edge surround 16 is dimensioned such that the concrete blocks 10 of the stone group 15 can be moved as a unit within the edge surround 16 on the table top 14.
- processing bodies 17 are moved over the (free) upper side of the concrete blocks 10 on the table top 14. A sufficient number of such stone bodies 17 is moved back and forth, possibly several times, over the top of the concrete blocks 10 without guidance, the processing bodies 17 executing a rolling or sliding movement, sometimes with a short lifting off from the top of the concrete blocks 10.
- the processing body 17 can consist of different materials, but from a harder material than concrete.
- the processing bodies 17 can be formed from granite, that is to say granite stones with corners and edges.
- the processing bodies 17 can also consist of metal. Different types of machining bodies 17 can be used together in order to achieve corresponding machining effects.
- the amount of the processing body 17 is guided over the top of the concrete blocks 10 using the dead weight.
- the stone group 15 is brought into an inclined position by a corresponding tilting movement of the table top 14. It is expediently possible to tilt the table top with different inclinations.
- the maximum inclination of the table top 10 or the stone group 15 can be 40 ° or up to 45 °.
- the entirety of the machining bodies 17 is moved from one side of the stone group 15 over this to the other side.
- the corresponding tilting movement of the table top 14 is carried out in the exemplary embodiment shown with the aid of pressure medium cylinder 18, 19.
- the tilting movement can take place in several directions, that is to say in the longitudinal and transverse directions to the processing table 13.
- the material for processing the concrete blocks 10, that is to say the processing bodies 17, are each used several times and are therefore part of the processing device.
- the processing table 13 is surrounded all around by a collecting basket 20.
- the lower part of the collecting basket 20 in the inclined position of the table top 14 collects the processing bodies 17 when they have been moved over the stone group 15. By moving into the other tilting position, the processing bodies 17 are then moved over the stone group 15 again and caught by the part of the collecting basket 20 on the opposite side.
- the concrete blocks 10 are in a special relative position during processing, that is to say when the processing bodies 17 are moved over the concrete blocks 10.
- the concrete blocks 10 are arranged in an offset position with respect to one another such that at least some of the (upper) edges, namely transverse edges 11 and longitudinal edges 12, protrude beyond adjacent concrete blocks 10.
- the concrete blocks 10 are arranged in an offset position with respect to one another such that at least some of the (upper) edges, namely transverse edges 11 and longitudinal edges 12, protrude beyond adjacent concrete blocks 10.
- the relative position of the concrete blocks 10 must be changed. This can be done by moving organs that raise or lower the concrete blocks 10 in changing positions.
- the concrete blocks 10 automatically reach offset processing positions.
- support members for the concrete blocks are arranged on the top of the table top 14, namely support webs 21. In the present case, these are arranged so that each concrete block 10 rests eccentrically and thus obliquely on a support web 21. If the table top 14 is tilted into a different, opposite inclined position, the concrete blocks slide with their underside along the supporting webs 21 into another, opposite inclined position, so that, for example, in Fig. 4 lower transverse edges 11 in an elevated position projecting beyond the adjacent concrete block 10.
- the support members can be designed and arranged in such a way that corresponding oblique positions are achieved with transverse tilting movements of the processing table 13.
- the concrete blocks 10 are arranged in stone rows 22 within the stone group 15.
- the support webs 21 are arranged such that a complete row of stones 22 is positioned in the manner shown in FIGS. 4 and 5.
- the treatment device described or the treatment process can advantageously be integrated into the process of manufacturing concrete blocks 10.
- 6 shows a block production plant in a schematic plan view. This consists of a stone molding machine 23. A layer of concrete blocks 10, that is to say a stone layer 24, is produced on a base board 25 in the area thereof. The freshly manufactured concrete blocks 10, that is to say the layer of stones 24, is conveyed on this support board 25 into the area of a lifting ladder 26. This stacks the underlay boards 25 one above the other, each with a stone layer 24. A unit consisting of a plurality of underlay boards 25 is then taken over by a fork-lift truck 27 and transferred to one of several drying chambers 28. In their area, the concrete hardens under the influence of heat.
- the concrete blocks 10 remain in the drying chambers 28 for a period of about 24 hours.
- the fork-lift truck 27 then removes the set concrete blocks 10 - on the underlay boards 25 - from the drying chambers 28.
- the underlay boards 25 are also included each a stone layer 24 again and promoted towards a stacker 30. This takes the set concrete blocks 10 or the stone layer 24 from the underlay board 25.
- the concrete blocks are fed via a conveyor 31 to a storage location for complete hardening over a period of 8 to 10 days.
- the empty underlay boards 25 are fed back to the stone molding machine 23.
- the concrete blocks 10 which have hardened over 24 hours do not immediately become a storage place promoted, but removed from the underlay boards 25 via a pre-stacker 32.
- the concrete blocks 10, namely the stone layers 24, are fed to the processing station, that is to say the processing table 13, by a cross conveyor 33.
- the dimensions are chosen such that a plurality of stone layers 24 together form a stone group 15 on the processing table 13.
- the finished concrete blocks 10 are expediently pushed into subgroups - corresponding to a stone layer 24 - from the processing table 13 to a conveyor 34. This transports the concrete blocks 10 to a storage location for hardening.
- the described processing of the concrete blocks 10 to produce an artificial aging is accordingly carried out before the concrete has set completely, namely after a curing process of approximately 24 hours.
- the transfer of the stone layers 24 to the processing table 13 and the pushing off of the processed concrete blocks 10 can expediently take place in such a way that the arriving concrete blocks 10 or stone layers 24 to be treated push the already processed off the table top 14 onto the conveyor 34.
