Definitions

  • the invention relates to a plate-shaped concrete block for covering streets, paths and squares.
  • Concrete blocks or paving stones are superior to black ceilings and other related covers as ground cover for streets, paths and squares in many ways.
  • the development of noise during rolling traffic (from vehicles) is perceived as disadvantageous.
  • the invention is based on the object of proposing a paving stone or shaped concrete block which, while maintaining the advantages of paving stones as a ground cover, significantly reduces the noise development due to the rolling traffic.
  • the invention is based on the knowledge that a noticeable reduction in the development of noise during rolling traffic can be achieved by the interaction of several features in the design of the paving stones or concrete blocks and the soil cover produced therefrom.
  • a significant contribution to sound absorption is made by the upper cross-sectional area of the concrete block, namely by the absorption layer made of porous concrete.
  • Paving stones with a layer of porous concrete are generally known.
  • the covering layer made of porous concrete serves to drain surface water. The sound-absorbing effect of the porous concrete has not yet been recognized.
  • the shaped concrete blocks are designed with a larger format, namely plate-shaped. Dimensions with an edge length of at least 30 cm, in particular square shaped concrete blocks with an edge length of 33 cm, have proven to be advantageous for noise reduction.
  • the porous concrete absorption layer is formed on the underside with a curvature so that the surface water can run off to the sides of the concrete block.
  • the concrete shaped blocks according to the invention are laid at very short distances from one another, that is to say with very narrow joints. This makes it difficult to drain the surface water.
  • the concrete blocks are therefore provided with upright water drainage channels, namely slots, on the side surfaces. These extend immediately below the absorption layer, so that the surface water reaches the upright slots and then the underground.
  • the invention further relates to a method for producing the shaped concrete blocks according to the invention.
  • DE-A-39 09 169 shows a method for producing a molded block with two layers.
  • the top of the molded block is shaped downwards.
  • a thin layer of rock is poured into the mold and pressed.
  • a layer of concrete is poured in and also pressed.
  • flat surfaces are created on the shaped stones.
  • the shaped block according to the invention cannot be produced with this device.
  • the method according to the invention is characterized in that the shaped stone is shaped with its upper side facing downwards in a mold, firstly a facing filler for forming the absorption layer and then a core filler for forming the stone body is poured and shaped into the mold in such a way that both the front filler as well as the core filling are arched, such that both fillings have a greater height at the edges.
  • the invention relates to a system for producing the shaped concrete blocks according to the invention.
  • FR-A-2 493 214 shows a system for producing a two-layer concrete block, in which a stamp with a relief-like underside is used. With this stamp, however, only the upper layer is pressed in such a way that a relief-like visible surface is created on the concrete block. Such a system is not suitable for the production of the shaped concrete blocks according to the invention.
  • the system according to the invention is characterized in that the mold stamp is curved such that both fillings can be shaped at a greater height at the edges.
  • Fig. 1 shows a shaped block 11 according to the invention, made of concrete in vertical section.
  • the shaped stone 11 consists of two layers, of which the first layer is the actual stone body 12, on which the second layer, an absorption layer 13, which is sound-absorbent, is applied.
  • the absorption layer 13 has a smooth upper side 14 which is part of the road surface in the case of a paving slab made of shaped stones 11. Since the top 14 is smooth, the rolling noise on the stone 11 is reduced.
  • the top 14 is formed with sharp edges, so no bevels are provided on the edges of the top 14.
  • the absorption layer 13 is porous.
  • the absorption layer 13 preferably has a grain size of 4 mm to 8 mm. This grain is cement-bound.
  • the binding can be achieved by additional binders, e.g. Plastic, preferably polymers, or silicate, be reinforced.
  • the top 15 of the stone body 12 on which the absorption layer 13 is applied is convex. It therefore has a dome shape, so that water or other liquids flow on this upper side 15 from the center to the edges.
  • the shaped block 11 has vertical slots 16, which are introduced into the side surface and through which the liquid can flow from the upper side 15 of the stone body 12 to the underside of the shaped block 11 and can then seep into the ground.
  • the slots 16 only extend from the underside 17 of the shaped block 11 to the absorption layer 13, and therefore do not run through the absorption layer 13. This ensures that the edges of the upper side 14 remain sharp-edged all around, that is to say there are no openings in the edge regions of the upper side 14.
  • paving stones to form a road surface can meet closely or almost completely, resulting in an almost seamless road surface on which the rolling noise of traffic is minimized.
  • the molded block 11 is shown somewhat compactly in FIG. 1, but it is preferably formed as large as possible in the form of a plate. Shaped stones 11 have proven to be favorable, the edge length (in the plan) being at least 30 cm. Optimal results are achieved with a shaped block 11 which is square with an edge length of 33 cm. In order to achieve an optimal support of the shaped stone 11 on a pavement base, the shaped stone 11 has a concave arch 18 on its underside 17. In the edge areas of the underside 17, peripheral bevels 19 are formed, which are relatively steep.
  • FIG. 2 shows a side view of the shaped block 11 according to the invention according to FIG. 1.
  • the same components are identified in FIG. 2 as in the other figures, with the same reference numbers as in FIG. 1.
  • FIG. 3 shows the shaped block 11 according to FIGS. 1 and 2 in a top view.
  • the porous upper side 14 is only indicated by dots in a corner region.
  • the arrangement of the slots 16 on the side surfaces of the shaped block 11 can be seen from FIG. 3.
  • FIG. 4 shows a manufacturing plant for the production of shaped blocks 11 according to FIGS. 1 and 3 in a schematic side view.
  • the production system comprises a vibrating table 20 on which a molding box 21 with molds 22 for shaping molded blocks 11 according to the invention is arranged.
  • This molding box 21 can be shaken in an up and down movement with the vibrating table 20, as indicated by a double arrow.
  • the production system further comprises two filling wagons 24a, b which can be moved on rails 23 and in which the two fillings for producing the two layers 13 and 12 of a shaped block 11 are stored.
  • At least the filling car 24a that receives the prefill for the manufacture of the absorption layer 13 has a metering device for the metered filling of prefill fillings to form absorption layers 13 in the molds 22.
  • mold dies 25 which can be lowered into the molds 22 are arranged.
  • the mold stamps 25 are suspended from a cross member 26 and can be moved up and down hydraulically, for example.
  • a header filling is first filled into the molds 22 and by lowering the mold stamp 25 into the mold Molds 22 formed into absorption layers 13.
  • the core filling is then filled into the molds 22 to form stone bodies 12. These are then also shaped by lowering the die 25 and compressed by shaking with the shaking table 20.
  • the shaped stones 11 are thus produced with their top 14 downward.
  • the formation of a sharp-edged top 14 is guaranteed.
  • FIG. 5 shows a road surface 27 made from shaped stones 11 according to the invention in a vertical section.
  • the shaped stones 11 Because of their specially designed underside 17, the shaped stones 11 have a particularly firm position on the material 28 of the paving base. In particular, the edge areas of the underside 17 between the bevels 19 and the arch 18 lie firmly on the material 29.
  • This road surface 30 consists of conventional paving stones 31.
  • the pressure curve P-X of the conventional road surface 30 has been indicated by the representation of the conventional road surface 30 in FIG. 6. It can be seen that the conventional paving stones 31 lie with their central areas with the highest pressure on the material 32 of a paving base. This leads to the fact that the conventional paving stones 31 are set into a rocking movement when subjected to traffic, as has been indicated in FIG. 7. Material 32 is pressed from the edge areas of the undersides of the paving stones 31 partly under the paving stones 31 to the middle and partly pumped up through the joints 33 between the paving stones 31. As a result, the pressure curve indicated in FIG. 6 becomes even more extreme, so that the rocking effect indicated in FIG. 7 becomes increasingly worse and the paving stones lose their hold more and more. Such rocking paving stones 31 even increase the driving noise of the vehicles.
