Definitions

  • the invention relates to a building system for a support structure comprising embankment stones according to the preamble of claim 1.
  • slope or slope securing stones have also become known which have a rectangular shape in plan view. Its upper circumferential edge is divided into two and lies at two heights, forming a heel step, the step being oriented in the longitudinal direction of the slope stones, that is to say in the direction of attachment of a next stone.
  • the next embankment stones which are offset by half the length of the embankment stones, can be supported on the step formed in a next higher row and thus contribute to an increased load transfer of the horizontal earth pressure and shear forces from the higher to the lower stone rows.
  • DE-C-3 118 031 discloses a building system for a support structure comprising plantable embankment stones according to the preamble of claim 1, in which the embankment stones have grooves running parallel to the side walls, in which tie rods with stop faces can be used.
  • these known tie rods are only suitable for the non-slip positioning of rows of blocks arranged one above the other and do not ensure the desired increased strength of the structure, which is required in particular in the case of a higher construction.
  • Modules are known from EP-A-0 381 147, on one side wall of which a groove-shaped depression is provided. Adjustment pieces can be inserted into this recess, which allow adjustment of rows of blocks arranged one above the other. By contrast, these adjusters do not create a connection between adjacent modules.
  • the slope stones according to the invention can be used to support slopes with more rows lying one above the other at the same slope angle than in the prior art.
  • connecting clamps are used which, on the one hand, chain two adjacent slope securing stones together and, on the other hand, have an upwardly projecting stop, via which, when installed, the earth shear and vertical forces introduced above and above the embankment stone as well as vertical forces onto the respectively installed embankment stones can be derived. Calculations have shown that an overall height of well over five to seven rows of stones is possible.
  • An essentially U-shaped recess or groove-shaped recess is preferably provided in the direction of attachment, with the further upper peripheral edge of the embankment stones running at the same height adjacent to this recess. This significantly reduces the risk of breakage in the edge area at the transition to the depression.
  • the legs or the upwardly projecting stop are at least slightly elastic.
  • the connecting clip preferably consists of a steel sheet.
  • the Elastic or at least partially elastic brackets can by no means be destroyed, damaged or kinked as easily as the abovementioned concrete lugs, which serve as stop steps for a row of embankment stones lying above them.
  • FIG. 1 shows two so-called plantable embankment or slope securing stones which are made of concrete and which, in the exemplary embodiment according to FIG. 1, have a rectangular shape in plan view and are open at the top and bottom.
  • the dimensions can vary widely.
  • the edge lengths can be 400 to 600 mm, preferably around 520 mm.
  • the shorter front edge length can be, for example, 300 to 400 mm in length.
  • the wall thickness is selected according to the requirements and can be, for example, 50 to 75 mm, preferably around 60 to 65 mm.
  • the slope or slope securing stone 1 shown in FIGS. 1 to 7 is open at the top and bottom and preferably has a thickening section or bead 3 in the lower peripheral edge region, as is only indicated in FIG. 3.
  • embankment stones 1 are generally aligned with one another in the longitudinal direction and are formed to form a plurality of rows lying one above the other, with a next higher embankment stone 1 being offset by approximately half the embankment stone length, that is, the parting line between two lower ones Embankment bridges bridged.
  • Each higher row is generally offset to the lower row in each case (Fig. 2).
  • the dashed line shown in Figure 3, resulting from the offset of a higher to the lower row angle ultimately also determines the height to which the plantable embankment stones may be installed one above the other, that is, with how many rows.
  • the embankment stones 1 are preferably filled with water-permeable material such as sand, gravel sand, etc. and slightly compacted in order to improve plant growth and prevent frost in the lower half.
  • the top half is supplemented with topsoil containing sand. No special foundation measures need to be taken if the ground is suitable. Otherwise, the known measures are applied.
  • the embankment stones 1 are provided with an essentially U-shaped recess or groove 7 in the attachment and concatenation direction, ie on their concatenation wall 6 on their upper circumferential edge 5, which otherwise runs at the same height, and which are of low height of, for example, only one centimeter.
  • the connecting bracket 9 also has a U-shape, with its overhead base connecting section 11 lying in the bed formed from the two adjacent grooves 7 in the upper circumferential edge 5 of two adjacent slope stones 1, and their downward-pointing legs 13 each on the associated one Inner wall 15 of the associated embankment stone 1 abuts.
  • the connecting clip 9 preferably consists of an elastic or at least partially elastic steel sheet.
  • the wall thickness can be chosen according to the needs. Dimensions from 6 mm to 12 mm are fully sufficient. Preferred dimensions range from approximately 8 mm to 10 mm.
  • legs 13 themselves can have a spacing dimension that is at least slightly smaller than the spacing dimension between the two inner walls 15, in other words generally smaller than the thickness of the two adjacent interlinking walls 9 of two neighboring ones by achieving a preload in the unloaded state Connecting bracket 9 of embankment stones 1.
  • the connecting clip 9 has an upwardly projecting stop 17, which can also be referred to as a flange or mandrel and protrudes beyond the plane of the upper peripheral edge 5.
  • the depth of the groove 7 in the respective peripheral edge 5 only has to correspond approximately to the thickness of the groove or recess 7.
  • the depth of the groove 7 can also be slightly greater than the thickness of the base connecting section 11 of the connecting clip 9.
  • the stop 17 is formed on the side boundary of the base section 11 of the connecting clip 9. It can also be made here like the legs 13 from a one-piece sheet metal by edges.
  • the stop 17 can also lie on the rear or slope side. This is possible by installing the connecting bracket 9 rotated by 180 °.
  • embankment stones deviating from this shape can also be used.
  • a modified embankment stone 1 is shown in plan view, which has a slight trapezoidal shape. That is, only the two long sides lie parallel to one another, the narrow sides 6 being oriented at an angle to one another.
  • the two end faces forming the respective interlinking wall 6 each run in a non-rectangular alignment with the two long sides.
  • the different length dimension of the long sides can vary, for example, by 2 to 10%. If necessary, the use of different embankment stones 1 with different trapezoidal shapes in horizontal cross section is also possible in order to have greater variability in the construction of different embankment lines. From Figure 5 it can also be seen that the outer contour of the embankment stones 1 can also be designed irregularly.
  • a curved slope line can also be created and reproduced using the trapezoidal slope stone shown in FIG. 5.
  • a straight slope line can be produced even with slope stones 1 which are trapezoidal in horizontal cross section.
  • the embankment stone 1 shown in FIG. 8 has a circular shape and is provided with an opposing concave arc section 27 in a partial circumferential area.
  • a respective next embankment stone or planting ring 1 can be inserted with its convex arch section into the concave arch section 27.
  • Plant ring for plant ring are placed one inside the other in the concave arch section 27 when the supporting structure is created, it being possible to create a series connection in accordance with the optionally curvilinear slope profile by rotating the respective subsequent plant ring.
  • each subsequent planting stone can also be rotated by the angular offset or a whole multiple thereof until two indentations or grooves 7 in the two circumferential edges 5 of the adjacent slope or slope securing stones 1 are aligned with one another.
  • the clip 9 mentioned and described does not always have to be anchored in a corresponding recess 7 in the peripheral edge 5.
  • a corresponding vertically extending recess 7 is also possible as an alternative or in addition to the recess 7 provided on the upper circumferential edge 5, into which the vertical legs 13 can then be inserted with appropriate spacing dimensions.
  • the upper base connecting section 11 can then rest on the peripheral edge 5, the connecting clip 9 then being provided by the engagement of the legs in that on the inner wall surface vertical groove in the slope stone 1 is held.
