Definitions

  • the invention relates to a shaped block with spacers in the form of cams and a kit with such shaped blocks.
  • spacers make it possible, for example, to maintain a minimum distance between the shaped stones when laying the shaped stones, so that rainwater can seep into the subsurface through the joints formed.
  • the spacers serve to prevent the shaped stones from sliding, so that they remain anchored in place when in use and do not move or tilt unintentionally.
  • Numerous designs of such spacers are known.
  • the spacers are often arranged at a regular distance so that, in the case of adjacent stones, spacers on one stone engage in gaps between spacers on the other stone. Such a system is in the EP 1432871 B1 disclosed.
  • the object of the invention is to create a shaped block which offers improved protection against movement with the smallest possible joint spacing.
  • Another task is to provide a kit of such shaped bricks.
  • the invention is based on a molded block, in particular made of concrete, for creating a ground cover, comprising a base body with an upper side and a lower side and four side surfaces parallel to a stone height with cams arranged on at least one side surface.
  • the void is preferably formed by a flat area of the side wall.
  • the cams are arranged in such a way that cams can engage in gaps between cams in the case of shaped blocks lying next to one another. Despite the empty space, there is a sufficient number of cams to ensure stable protection against displacement.
  • the shaped stone is particularly suitable for heavily used and also traveled areas where a particularly reliable protection against movement is desired.
  • particularly narrow joints can be formed between adjacent shaped stones in a covering made of shaped stones.
  • the void allows the introduction of an additional volume of joint filling material between adjacent shaped stones, which secures adjacent shaped stones against one another.
  • a favorable joint filling material is, for example, sand or fine gravel with a suitable grain size.
  • the first and last cams are preferably designed within the grid unit and one of the internal cams is replaced by a space.
  • the shaped block can be an essentially flat element whose width and / or length is greater than its height, or a cuboid whose height is equal to or greater than its width and / or length.
  • a depth of the cams is advantageously in a range of a few millimeters, in particular in the range between 2 mm and 5 mm.
  • the height of the cams is measured from the underside of the shaped block.
  • the cams can end below the top of the shaped block.
  • the shaped block is preferably intended to be laid without a press fit, with the result that a joint spacing between shaped blocks is greater than the greatest cam depth.
  • a preferred basic dimension or stone dimension of the molded stone is, for example, 150 mm, which in the usual way corresponds to the clear width of the molded stone with cams close to the edge and also takes into account the intended joint width.
  • the pure edge length of the shaped block is therefore slightly smaller than the grid unit, which, however, is practically insignificant due to the small cam depth.
  • the grid unit can advantageously begin with a cam on an edge of a side surface and the same grid unit or a further grid unit can end with a gap on the opposite edge of the same side surface.
  • the outer cams in the grid unit can advantageously have a smaller depth than inner cams.
  • the cams in the grid unit can form two types, which differ at least in terms of their depth.
  • the two different depths can differ by 1 mm.
  • the volume around the cams with a shallower depth can accommodate additional joint filling material. It is particularly advantageous that no press fit is required between the shaped blocks when laying, so that a joint can also run through between the side walls and cams between the shaped blocks.
  • the outer cams in the grid unit can have a smaller depth than inner cams. This offers protection against displacement as well as the possibility of being able to insert more joint filling material between shaped stones.
  • the grid unit particularly advantageously begins with a cam on one edge of a side wall and ends with a gap on the opposite edge of the same side wall.
  • an integral number of grid units with cams and spaces can be formed on at least two, in particular on all side surfaces.
  • at least one grid unit is formed on a side surface.
  • the grid unit is slightly larger than the pure edge length of the side surface, taking into account the joint size.
  • a grid unit can be formed on the side surface.
  • two, three or more grid units can also be formed on the side surfaces.
  • the same number of grid units with cams and spaces can be formed on all side surfaces.
  • the grid unit can have the same dimensions for a wide variety of stone sizes. This makes it easier to assemble molded stones from a kit of molded stones.
  • At least two grid units with cams and spaces can be formed on a long side surface.
  • the grid unit can have the same dimensions for a wide variety of stone sizes. This makes it easier to assemble molded stones from a kit of molded stones.
  • two smaller cams and one large cam can be arranged in a grid unit. Due to the presence of small cams, spacers are present on the one hand, and on the other hand the space above the small cams offers space to accommodate joint filling material and to further stabilize the joints between adjacent shaped stones.
  • the cams can be designed in at least two different heights.
  • one of the heights can be 1/3 of the stone height and the other 2/3 of the stone height. This means that a particularly large amount of joint filling material can be introduced between adjacent shaped stones.
  • the cams can be designed in at least two different heights and the smaller cams have a smaller depth.
  • the absorption capacity for joint filling material can hereby be further improved.
  • the cams can be designed in at least two different widths.
  • the load on the cams can be adapted to typical conditions of use.
  • the cams can essentially be designed as flat webs. This allows simple shapes for the production of the molded block.
  • the cams can have the same width or the cam width can be different between different cams.
  • the width can vary along a cam.
  • the base body can have a profiling on the underside as a means of securing it against displacement.
  • the profiling on the underside can have continuous parallel grooves extending from one side surface to the opposite side surface. These can have trapezoidal cross-sections. Double grooves can optionally be provided, with a further groove being let into the groove bottom of one groove.
  • other profiles can also be provided, for example recesses within the base area.
  • a kit made of shaped blocks according to the invention is proposed.
  • the shaped blocks of different longitudinal and transverse dimensions have the same dimensions of their grid units.
  • the kit with shaped stones is particularly suitable for heavily used and also traveled areas where particularly reliable protection against movement is required. At the same time, particularly narrow joints can be formed between adjacent shaped stones.
  • the void allows the introduction of an additional volume of joint filling material between adjacent shaped stones, which secures adjacent shaped stones against one another.
  • a favorable joint filling material is, for example, sand or fine gravel with a suitable grain size.
  • the shaped stones are preferably intended to be laid without a press fit, with the result that a joint spacing between shaped stones is greater than the greatest cam depth.
  • a part of shaped blocks can be provided in which at least two edge lengths are a half or a quarter of the grid unit.
  • the arrangement and placement of the cams in these "partial stones" in the form of half or quarter stones corresponds to the arrangement in, for example, a square shaped stone with an edge length corresponding to a grid unit. This results in a varied and attractive look when laying stones of different side dimensions.
  • Figure 1 shows a plan view of a square shaped block 100 according to an exemplary embodiment of the invention, each with a grid unit 60 of cams 62, 64, 68 and blank 66 per side surface 30.
  • the molded block 100 comprises a base body 10 with an upper side 12 and a lower side as well as four side surfaces 30 parallel to a stone height 18 ( Figures 3 , 4th ).
  • Cams 62, 64, 68 are arranged on each of the side surfaces 30.
  • the cams 62, 64, 68 are arranged in a grid unit 60, which offers space for a number of, in this example, four cams 62, 64, 68 arranged equidistantly from one another, with only three cams 62, 64, 68 being formed and one Space 66 is provided instead of the non-formed cam.
  • the outer cams 62, 68 are preferably implemented, and the void 66 replaces one of the inner cams. In the embodiment shown, every third cam is omitted and replaced by the blank 66.
  • the grid unit 60 is as long as the edge length of the side surface 30 plus the depth of the cams 62, 68 close to the edge on the two adjacent side surfaces, so that each side surface 30 has at least one entire grid unit 60.
  • An integral number of grid units 60 with cams 62, 64, 68 and spaces 66 are formed on all side surfaces 30, 40, 50.
  • the distance between adjacent executed and non-executed cams 62, 64, 66, 68 is slightly more than one cam width, for example 1.5 times the cam width, so that when molded blocks 100 are placed against one another, no press fit occurs between the cams 62, 64, 68.
  • the first cam 62 begins at one edge of the side surface 30.
  • the last cam 68 is slightly more than one cam width away from the subsequent other edge of the side surface 30.
  • the grid unit 60 advantageously begins with a cam 62 on an edge of a side surface 30, 40, 50.
  • the same or a further grid unit 60 ends with a gap on the opposite edge of the same side surfaces 30, 40, 50.
  • the outer cams 62, 64, 68 in the grid unit 60 can have a smaller depth 70 than inner cams 68.
  • the cams 62, 64, 68 are web-like and have a trapezoidal cross-section in plan view.
  • the depth of the cams 62, 64, 68 is only a few millimeters and is preferably in the range from 2 mm to 5 mm.
  • Figure 2 shows a plan view of an elongated molded block 100 according to an exemplary embodiment of the invention, each with a grid unit 60 of cams 62, 64, 68 arranged and a blank 66 on short side surfaces 40 and two successive grid units 60 on long side surfaces 50.
  • Figure 3 shows an isometric view of a square shaped block 100 according to an embodiment of the invention Figure 1 with cams 62, 64, 68 of the same height in the grid unit 60.
  • the cams 62, 64, 68 begin on the underside 16 of the shaped block 100, extend parallel to the block height 18 and end below its upper side 12.
  • the arrangement of the cams 62, 64, 68 and spaces 66 corresponds to the description in FIG Figure 1 . Accordingly, the molded block 100 has two different types of cams: flat cams 62, 68 with a small cam depth 70 and thicker cams 64 with a greater cam depth 72 than the flat cams 62, 68.
  • FIG. 10 shows an isometric view of the square shaped block 100 according to an embodiment of the invention Figure 1 with cams 62, 64, 68 of different heights.
  • Figure 5 shows a detail of a longitudinal section through the molded block 100 in FIG Figure 4 to explain cam depths 70, 72 and cam heights 74, 76, and
  • Figure 6 shows a top view of cams 62, 64, 68 with emphasis on the different cam depths 70, 72.
  • the molded block 100 On its underside 16, the molded block 100 has a profiling 20 on the underside as protection against displacement, which is designed, for example, in the form of parallel grooves 22 which can be stepped ( Figure 4 ) or simply executed ( Figure 5 ).
  • the arrangement of the cams 62, 64, 68 and spaces 66 corresponds to the description in FIG Figure 1 .
  • the molded block 100 In its grid unit 60, the molded block 100 contains two smaller cams 62, 68 on the outside and a large cam 64 as well as the empty space 66.
  • the smaller cams 62, 68 are half as high as the large cams 64.
  • the representation in Figure 5 is not to scale.
  • the small cams 62, 68 preferably have a height 74 of only about 1/3 of the stone height 18, while the large cams 64 preferably have a height 76 of 2/3 of the stone height 18.
  • the small cams 62, 68 also have a smaller cam depth 70 than the large cams 68 with a cam depth 72.
  • the cam depths 70 and 72 preferably differ by 1 mm.
  • the molded block 100 has two different types of cams: flat, small cams 62, 68 with a small cam depth 70 and a low cam height 74 and large cams 64 with a greater cam depth 72 and greater cam height 76 than the no cams 62, 68.
  • Preferred cam depths 70, 72 in a molded block 100 with a block height 18 of 8 or 10 cm are, for example, 2 mm for the cam depth 70 of the small cams 62, 68 and 3 mm for the cam depth 72 for the large cams 64.
  • Preferred cam depths 70, 72 in a molded block 100 with a block height 18 of 12 or 14 cm are, for example, 3 mm for the cam depth 70 of the small cams 62, 68 and 4 mm for the cam depth 72 for the large cams 64.
  • Preferred cam depths 70, 72 in the case of a molded block 100 with a block height 18 of 16 cm are, for example, 4 mm for the cam depth 70 of the small cams 62, 68 and 5 mm for the cam depth 72 for the large cams 64.
  • the cams 62, 64, 68 are designed with the same width.
  • different cams 62, 64, 68 can also have different widths.
  • Figure 7 shows a detail of a longitudinal section through a shaped block 100 with a profiling 20 on the underside with double grooves 22.
  • Shaped block according to one of the preceding claims, characterized in that the base body 10 has a profiling 20 on the underside as a means of securing it against displacement.
  • the profiling 20 on the underside 18 of the molded block 100 according to the invention has several, for example seven, grooves 22 which are arranged parallel to one another and at the same distance.
  • the cross section of the grooves 22 is defined by two trapezoids which are arranged one above the other and taper in the direction of a maximum groove depth.
  • the two trapezoids are characterized in cross section, starting from a first flat surface on the underside 16, by a first slope, a second flat surface, a second slope and a third flat surface at the maximum groove depth.
  • the flat surfaces form shear surfaces, the slopes form abutment surfaces.
  • the depth of the stepped grooves 22 in this way is preferably selected so that individual grains of a bedding material can connect two flat surfaces to one another by bridging the shear surfaces.
  • the compacted grain packing of the bedding can then bridge all three flat surfaces and thus bridge all three shear surfaces.
  • the resistance to shear forces can thus be increased.
  • these shear surfaces press the bedding in the direction of the subsoil (e.g. the foundation surface of a road surface).
  • the aggregate of the bedding cannot move upwards at these points, so that forced compaction is advantageously brought about.
  • the stepped groove shape leads to an increase in the resistance to shear forces, in particular when the shaped block 100 with the grooves 22 is laid transversely to the direction of travel. If, for example, a vehicle brakes in the direction of travel, the resulting braking forces can act on the abutting surfaces of the grooves 22 opposite to the direction of travel and counteract any dragging of the molded blocks.
  • Figure 8 shows a plan view of a kit 200 of molded blocks 100 according to an embodiment of the invention.
  • the shaped stones 100 in the kit 200 can have different edge dimensions and can be assembled to form a desired covering without a press fit.
  • the shaped blocks 100 advantageously have the same dimensions of their grid units 60.
  • In the top view it can be clearly seen that there is always a free space between the cams, which can be filled with joint filling material during laying.
  • Figure 9 shows, as a variant, a top view of two half-stones 102 of the square shaped stone 100 from Figure 1 according to an embodiment of the invention.
  • the closed lines around the half-stones 102 indicate the usual stone dimensions, in which the joint width is also taken into account.
  • the square shaped block 100 is divided into two halves. If the square shaped stone 100 has a stone size of 150 mm x 150 mm, the stone size of the half-stone 102 is 150 mm x 75 mm.
  • the cams and spaces there are arranged with the same spacing and pattern as in the undivided molded block 100. Accordingly, only the respective upper and lower side surfaces have the cams and spaces of the grid unit 60, while the right and left side surfaces in the figure each only have a part of the Have grid unit 60. Overall, however, when the two half-stones 102 are put together, the grid unit 60 with cams and spaces is again present on the outside of the composite of the two half-stones 102.
  • Figure 10 shows, as a further variant, a plan view of four quarter stones 104 of the square shaped stone 100 Figure 1 according to an embodiment of the invention.
  • the closed lines around the quarter stones 104 indicate the usual stone size, in which the joint width is also taken into account.
