Abstract

The invention relates to a covering for a sloping surface or a support for a sloping surface, especially for plant growth which, in the area of the sloping surface, comprises at least one receptacle and/or support for covering or supporting means, in particular for solid body vegetation material which is capable of rooting. The aim of the invention is to create a covering or support for a sloping surface or an accompanying structural element which are characterized by having a simple construction, relatively small cross-section dimensions and a low degree of complexity. The covering or support for a sloping surface is characterized in that the receptacle or support comprises at least one planar grating (GT) which is elastic in shape at least in sections and which extends at least partially along the sloping surface (HO). Said receptacle or support also comprises at least one net (NT) which is provided with narrower openings than the grating and/or is provided with meshing, and which is secured on said grating by form-fit and/or material-fit in a planar overlapping manner.

Description

Slope cladding or slope support and associated component

The invention relates to a slope cladding or slope support, in particular for vegetation, in which at least one receptacle and / or holder for cladding or support means, in particular for solid vegetation material capable of root penetration, is arranged in the region of the slope surface. The subject matter of the invention also includes a corresponding component. In the present context, the term "slope" has a broad meaning, which e.g. also extends to rock faces. The subject matter of the invention therefore also includes cladding or supports for more or less bare rock walls.

Commonly encountered cladding and support structures of a known type are designed as stable and supportable wall structures with relatively large cross-sectional dimensions and exist e.g. made of heavy, frame-like or truss-like, superimposed components. Another known type of cladding and support structure comprises pillars or upright longitudinal members which extend essentially over the entire slope height and which in turn are anchored in a stable or supportive manner in foundations or by means of tension elements in stable background material of the slope. Cross beams, which generally extend horizontally, are attached between adjacent pillars or longitudinal beams at relatively small mutual distances.

The well-known cladding and support structures find their preferred application for heavily exposed and slippery slopes. The high effort and space required due to the large cross-sectional dimensions is undesirably high for numerous applications. The object of the invention is therefore Creation of a slope cladding or slope support or an associated component, which are characterized by simple construction and relatively small cross-sectional dimensions and the same effort. The inventive solution to this problem is determined by the features of claim 1 and claim 9, respectively. Essential and advantageous developments of the invention are determined by the features of the subordinate. Neten claims, which are particularly applicable in different, meaningful combinations with each other.

The underlying inventive idea underlying the objects of claims 1 and 9 consists in connection with the other common or equivalent claim features in the arrangement of a cross-area, lattice or lattice-shaped cladding or support element that a distributed absorption and transmission of the slope forces and thus enabling a space-saving and relatively simple, and thus also cost-saving anchoring structure.

The invention is further explained with reference to the exemplary embodiments shown schematically in the drawings. Herein shows:

1 shows a vertical cross section of a first embodiment of a slope cladding according to the invention with grid and network receptacle for vegetation material,

2 shows a vertical cross section of a second embodiment of a slope support according to the invention with a half-timbering stem and supporting pillar,

3 shows a vertical cross section of a third embodiment of a slope support according to the invention with a half-timbering stem and a tension / compression support element,

4 shows a vertical cross section of a fourth embodiment of a slope support according to the invention with truss stem and tension support element, and 5 shows a vertical cross section of a fifth embodiment of a slope support according to the invention with a half-timbered stem and a lightweight support pillar.

The slope cladding according to Fig.l is particularly intended for plant growth. In the area of the slope surface, at least one holder and / or holder for vegetation material (VM) capable of rooting is arranged, for example humus with growth agents, seeds and the like. The holder or holder comprises at least one areal, which extends at least partially along the slope surface (HO) , at least in sections, form-elastic grid part (GT) and at least one power supply unit (NT) which is secured to this grid part across the entire surface in a form-fitting and / or cohesive manner and is provided with narrower openings and / or meshes with respect to the grid element. A receiving space (AR) for the vegetation material (VM), which is arranged in front of the slope surface, is formed by spacers (AH) anchored in the area of the slope surface and on the other hand connected to the power supply unit (NT) and / or the grid part (GT). Accordingly, a plurality of such receptacles can be provided one above the other and / or next to one another. In the example, a power supply unit (NT) that is flexible at least in sections is provided, which is connected to the grid part (GT) or a plurality thereof by connections (AS) arranged in a grid pattern over at least part of the slope surface (HO). A major advantage results from the use of a power supply (NT), the mesh of which is formed from non-rotting and corrosion-resistant fiber or strand material, preferably at least partially from mineral fibers, in particular from glass fibers, which are extremely important in the case of bush or forest fires and are extremely fire-resistant. Specifically, in the construction shown in the example, spacers (AH) inserted into a fixed part of the slope surface (HO) or a cladding or support element are provided, the stops or brackets for a power supply unit (NT) acting in the normal direction to the slope surface (HO) ) and / or grid part (GT). The features of the invention described so far also come into consideration for slopes in the form of rock walls which are to be provided with cladding, in particular planting or also a securing means against rock which is detached from one another. The following features, which are also implemented in accordance with FIG. 1, are, however, suitable for slopes with a surface which is not or not very stable in the surface area. The following construction is recommended here:

The slope surface (HO) is provided at least in sections with a base layer (TS), in particular with a shotcrete layer. The latter has protruding spacers (AH) on the outside for the attachment of areal, immersion and growth-permeable erosion protection elements (ER), in particular of mesh or grid parts. These spacers are expediently connected to the base layer (TS) by adhesive or expansion dowels. The spacers (AH) and erosion protection elements (ER) form a receiving space (AR) or a plurality of them for vegetation material (VM) in front of the base layer (TS). The base layer (TS) itself is connected to load-bearing areas in the slope background by tie rods (ZA).

The slope support shown in FIG. 2, which can also have a cladding and greening function, is distinguished by the following features:

Support and / or anchoring elements, for example in the form of support pillars (SP), and at least one stem (VB) connected to these elements are provided within the slope width. The latter is designed here as a cross-sectional framework (FW1) that is capable of withstanding earth pressure and bending moments and can optionally include a plurality of such frameworks. The framework itself comprises a plurality of beams arranged parallel or at an acute angle to one another and to the horizontal, preferably in the form of metallic profile beams (PF). The framework can in particular be designed as a self-supporting, prefabricated structural unit, preferably wise as a framework. In each case a truss assembly is connected to at least one support pillar (SP) anchored in the area of the slope foot via at least one support connection (TA) arranged in the area of its upper half height. In this way, the inherent load-bearing capacity or bending strength of the truss (FWl) is exploited in order to simplify and reduce the cost of the support pillar (SP). In addition, there is the advantageous possibility of minimizing the bending moments in the truss due to the earth pressure by dividing the position of the support connection (TA) within the height dimension of the truss at least approximately according to a continuous beam.

The embodiment shown in FIG. 3 is characterized by the fact that a truss (FWl) has at least one support connection (TA) arranged in the area of its upper half with at least one dimensionally stable tension / pressure support element anchored in load-bearing slope material or slope base ( ZDE) is connected. This provides another desirable way to simplify and reduce the cost of construction. This applies even further to the embodiment according to FIG. 1 which, instead of the tension / compression support element, has a preferably flexible and therefore particularly simple and inexpensive tension support element ZE with a correspondingly designed support connection TA. However, the use of this construction requires a corresponding strength of the slope background in order to ensure a secure anchorage.

In the embodiment according to FIG. 5, the truss (FW2) consists at least partially of metallic profiled beams (PF) which are suspended in form-fitting mounting brackets (HN) from supporting pillars (SP) anchored in the area of the slope foot. Such a construction is particularly suitable for pillar arrangements, which are stabilized in position by the weight of the slope material resting on them and are therefore capable of being supported. As indicated in FIG. 5, this can be optimized by means of support strips (TL) which extend laterally and / or rearward into the material of the slope or foot of the slope. It is understood to be essential to the invention that, with special advantages, the slope cladding or slope supports of the type shown in FIGS. 2 to 5 on the front of the framework (FW1, FW2) have at least one receptacle and / or holder for solid vegetation material capable of root penetration with at least one flat erosion protection element (ER), in particular with at least one dimensionally stable grating part (GT). as well as with at least one power supply unit (NT) that is secured in a form-fitting and / or cohesive manner across this grating part.
