Definitions

  • the invention relates to a concrete block for landscaping and garden design according to the preamble of claim 1.
  • the concrete block is designed in particular as a heavy slope stone and is primarily suitable for the erection of retaining walls on embankments, as a vertical wall or as individual troughs that are planted allow.
  • the stone is intended for dry construction, d. H. the components are joined together without mortar.
  • Such a component has become known, for example, from EP 0 187 615 A1.
  • the components of this known kit have dovetail grooves on their end faces or dovetail springs which fit into them in order to connect these components directly to one another. This provides a certain stability of the structure even when stacked on top of one another by a positive connection. It is also not necessary to make these components particularly large and heavy, since the form-fitting anchoring of the shaped blocks offers mutual support.
  • EP 0 215 994 B1 provides a similar solution for joining trough-like shaped stones, with additional ones Wall elements with dovetail-shaped connecting ends in turn allow a positive connection of non-adjacent troughs.
  • the stability of the system in the manufacture of embankment walls or walls with overlying troughs is brought about by form-fitting anchoring elements.
  • the known trough-shaped elements have a bottom that is open towards the bottom for filling with soil, the problem of safe stackability arises in these arrangements, which in particular causes problems in an offset arrangement of the shaped stones with respect to one another.
  • additional form-fitting anchoring elements are provided in order to ensure that the troughs cannot tip over when stacked one above the other, in particular also in a staggered arrangement.
  • the shaped stones are primarily offset from one another only in the direction of the slope, while lateral offset from one another is avoided as far as possible.
  • the invention has for its object to propose a concrete block, which is particularly difficult Hangstein can be used for an embankment attachment or as a component for a vertical wall, positive locking anchoring elements between the elements in the form of anchoring elements engaging in undercuts being to be dispensed with.
  • an elegant shaped stone is to be designed, which can be erected in a very short assembly time without problems, even on rough terrain.
  • the construction should be carried out using conventional devices such as cranes, excavators, forklifts or the like. It is a further object of the invention to make the shaped concrete block geometrically as simple as possible, so that simple production is made possible.
  • a visually attractive and plantable unit in particular as a wall or slope unit, is to be created.
  • post-processing of the components for object-related solutions should also be as simple and efficient as possible.
  • the kit should be limited to as few components as possible, in particular positive locking anchoring should be avoided.
  • the invention is based on the main idea that dispensing with any form-fitting anchoring in the built-up system, for example an embankment wall, makes it necessary for the concrete shaped blocks to form a correspondingly good contact surface with one another, in particular offset from one another.
  • the elegant shape of the body is to be achieved through a special shape so that the shaped concrete block does not appear globular. This is achieved by using a body with a square or rectangular plan in the corner areas cuts off clearly by 45 °, so that the shaped stone is almost octagonal in plan.
  • the outer surfaces of the body can be cambered or polygonal, but also just designed.
  • the element height is preferably chosen so that the ratio of element height to element width is approximately 1: 2 in order to convey a pleasing appearance.
  • the shaped body is essentially designed as a hollow body in a trough shape.
  • the inner walls are strongly tapered in order to achieve a large, ie wide, contact surface at least in the lower region of the trough-shaped trough stones.
  • the elements can be stacked one on top of the other in a tilt-proof manner and displaced to a high degree in all directions, the bearing surface on the body underneath being largely retained.
  • conical inner walls are also provided in the lower region of the troughs in the prior art according to EP 0 187 615, these serve only to support an inner base without the support surface of the trough itself being significantly enlarged in the lower region.
  • the aim of the invention is to design the lower contact surface of a trough which is open towards the bottom by means of a strong conicity such that a significantly larger and sufficient contact surface is achieved to improve the stability of troughs stacked one above the other.
  • embankment walls or vertical walls can be built, which do not require any anchorages between the troughs or dowels in the vertical direction or other measures. If additional slide-in walls are provided between the individual trough elements, these form In the present system, no form-fitting anchors, since they are only inserted in the appropriate recesses in the manner of a tongue and groove connection. Here, the shaped blocks are supported laterally against one another via such wall elements.
  • the shaped concrete block shown in FIG. 1a in top view and in FIG. 1b in side view is designed as a heavy slope stone or heavy trough element and has a weight of approximately 500 kg.
  • the shaped block is constructed symmetrically to the longitudinal symmetry plane 2 and to the transverse symmetry plane 3.
  • the walls 5 next to the corner areas 4 are preferably cambered or also polygonal in accordance with the plan view in FIG. 1a. This also gives the very large and massive stone a pleasing appearance. However, they can also be flat.
  • the corner points of the basic square cross section with the side length a are identified by reference number 8.
  • the strongly cut corners result in an almost octagonal basic cross-section.
  • the shaped concrete block 1 has on the outside essentially vertical or vertical outer walls 5 or corner regions 4.
  • the crowning or rounding can also be polygonal, as shown in FIG. 1b with the three surface sections 5 ', 5''and5'''.
  • the widths d 1 of the central surface section 5 ′ and widths d 2 of the lateral surface sections 5 ′′, 5 ′′ ′′ are of the same order of magnitude as the width b of the corner region 4.
  • the outer walls 4, 5 can also be downward be conically widening.
  • the shaped block is designed as a hollow body with an upper surface 9, a lower surface 10, an inner cavity 11 and a conical inner wall 12.
  • the conical inner wall 12 can in principle follow the course of the outer wall 4, 5 of the shaped block in cross section or in plan view with a continuously widening wall downwards and without crowning or polygonal course.
  • the wall thickness s consequently has an upper wall thickness s 1 and a lower wall thickness s 2 , the ratio of the wall thicknesses s 1 : s 2 ⁇ 1: 2.
  • a very wide contact surface with the circumferential wall thickness s 2 is formed on the bottom or on the lower surface 10 of the shaped block.

  • the pockets 13 have a width of g ⁇ 80 mm and a depth of t ⁇ 60 mm.
  • the pocket-shaped recesses 13 preferably run slightly conically inwards (g> g ').

  • the insert plate 15 is adapted to the lower contour of the inner cavity 11 of the shaped block 1, i. H. it in turn follows the conical wall of the inner cavity and has a corresponding outer cone angle ⁇ .
  • the conical inner wall 12 of the inner cavity 11 is not cambered or polygon-like for easier manufacture, but is designed as a flat surface, i. H. the inner wall 12 runs parallel to the square outer cross section through the corner points 8 and parallel to the beveled corners 4 with a corresponding conical taper.
  • FIGS. 3a, 3b show the large contact surface of the shaped blocks according to the invention.
  • 3b shows a shaped block 100 which has no conical inner contour, ie the wall s 3 is approximately constant over the entire height of the trough block.
  • An increase in the contact surface in the embodiment according to FIG. 3b could therefore only be achieved by placing the entire side walls directly on top of one another, which, however, may be undesirable.
  • FIG. 3a A comparative illustration with shaped stones according to the invention is shown in FIG. 3a.
  • 4a, 4b show a similar representation, but with shaped blocks arranged spatially offset. If shaped blocks with the same wall thickness, that is to say without conical widening of the wall in the floor area, are used according to FIG is determined by the wall thickness S 3 .
  • FIG. 4a shows the same arrangement with a shaped block according to the invention.
