Definitions

  • the invention relates to a method for producing or treating concrete blocks, in particular paving blocks of various formats and sizes, the production taking place in molds filled with concrete and stamps corresponding to the stone surface for embossing the surface and visible edges and the concrete blocks subsequently hardening.
  • edges of the stamp usually have uniform or uneven strips, so that correspondingly beveled or rounded visible edges are formed on the concrete blocks.
  • GB-A-944,706 discloses a process for the production of decorative panels, using a stamp which has a structured surface for producing the decorative appearance of the panels. However, it is a process for producing panels from synthetic mineral fibers such as glass wool, rock wool and slag wool, the panels being used for sound insulation purposes. Such a method is therefore not suitable for the production or treatment of concrete blocks.
  • the object of the present invention is therefore to provide a process for the production or treatment of concrete blocks which fits the customary production process and at the same time brings about a desired treatment of the edges of the concrete blocks.
  • the punch is deliberately made smaller than the associated shape and therefore a burr is formed, the burrs can of course be broken off and the concrete blocks roughened only in the edge area.
  • the gap between the punch and the shape can be uneven, so that an uneven burr and an uneven edge are produced.
  • the features, deliberately kept small stamp and making recesses or projections (claim 3) on the smooth stamp surface or in the area of the strips, can also be combined, so that both the breaking off of the burrs roughening or damaging the surface and edges of the concrete blocks can also be used simultaneously.
  • the roughening or damage to the surfaces can take place irregularly or unevenly through the recesses or projections of the stamps or the formation of the burrs and / or the subsequent processing.
  • the projections in their simplest form can be formed by welding spots or weld spot accumulations on the stamps and can extend both over the flat surface of the stamp and the edge strips, so that roughening or damage to the entire surfaces visible in the laid state of the concrete blocks he follows.
  • the projections or recesses can also only in the area Strips are attached so that the visible edges of the concrete blocks are preferably roughened or damaged.
  • the projections or recesses have undercuts, so that when the stamps are lifted off, the edges in the concrete blocks are torn or torn around the projections or recesses, so that corresponding roughening results.
  • nozzles are provided, the openings of which are directed towards the stone surface. You can both be aligned vertically but also preferably at an angle to the surface and to the visible edges. Advantageously, several are at an angle to each other for efficient production arranged nozzles provided, wherein the nozzles can be moved both uniformly and unevenly to the concrete blocks.
  • the material emerging from the nozzles can be air, water, sand, metal bodies or a mixture of these materials.
  • the concrete blocks can also be moved uniformly or unevenly in the subsequent work step, namely by means of nozzles or brushes.
  • nozzles or brushes Particularly when a burr is to be broken in the area of the edges of the concrete blocks, it is recommended that both the movement of the brushes and the alignment of the nozzles are angled to the burrs, so that a simplified breaking off of the burrs is ensured.
  • the part of the stamp which is in operative connection with the concrete blocks is made of rubber or plastic and is fastened to the stamps.
  • the attachment can be done advantageously by vulcanization or by gluing. But it is also possible that this part is fastened to the punches by fastening screws, which are preferably designed as countersunk screws.
  • the part made of rubber or plastic contains the recesses or projections and the like with the undercuts which may be provided.
  • the elasticity of the part made of rubber or plastic creates a denser surface structure and, moreover, the elasticity means that the surface is even better embossed or treated.
  • the production device of FIGS. 3 and 4 has play between the molds 2 and the punches 3, so that burrs 7 are formed during the stamping.
  • FIG. 5 schematically shows a device for carrying out the downstream work step, which has a rotating shaft 8 to which brushes 9 which are arranged eccentrically are fastened.
  • the brushes are designed essentially in the shape of a truncated cone, so that they in particular rework the visible edges of the concrete blocks 1 and thereby remove the loose parts of the concrete blocks and, if necessary, roughen or damage the visible edges. This results in concrete blocks 1, the visible edges of which are shaped according to the cuts through FIGS. 8 to 10.
  • the concrete blocks 1 or their visible edges are processed by nozzles 10 according to FIG. 6 or flat nozzles 11 according to FIG. 7, the loose particles being thrown away and the surface additionally roughened or respectively is damaged.
  • This damage depends on the one hand on the material that flows through the nozzles.
  • This material can consist of air, water or other blasting material such as sand or metal bodies, but also a mixture with air or water.
  • the inflow of material can also take place uniformly or intermittently and both the nozzles 10 and 11 and the concrete blocks 1 can move in relation to one another as desired.
  • the angle at which the blasting material hits the concrete blocks or the visible edges also plays a role. It is also important how the surface of the stamp 3 or its recesses 5 or projections 6 are formed and when the subsequent operation takes place, i.e. how far the concrete blocks have already set.
  • a concrete block 1 is sketched in perspective, which has holes both on the surface, which were formed based on the projections 6 in the punches 3 and then through the downstream Work step was modified and expanded. The same also applies to the visible edges of the concrete block 1 according to FIG. 11.
