    专利说明:

    The present invention relates to a cladding for a wall shell for fastening slopes, embankments, etc. in particular on paths, roads of any kind but also waters, which is arranged as a facing wall spaced from the wall shell in front of this, and a method for producing a such disguise.
    In this wall shell, it can basically be a shotcrete shell (anchored back or not), bored pile wall or a sheet pile wall filled with in-situ concrete in the spaces. It is known to provide slopes with a shotcrete shell, in particular to prevent rocks from falling. After the shotcrete shell has been applied, it is usually clad with in-situ concrete, on the one hand to provide additional support and, on the other hand, to create an optical design. Various facing elements can also be inserted through stones. The production of such a cladding is very time-consuming, especially if an additional optical design is also carried out. It is also known to manufacture the facing wall at the factory, with the side of the facing wall facing away from the shotcrete shell already being provided with a visually appealing facing. The complete attachment wall is transported from the factory to the construction site, where it is erected and fastened. This significantly accelerates the implementation of the construction project, since the shotcrete shell can be clad very quickly on site after the shotcrete shell has been completed. From US Pat. No. 5,551,810 A, a cladding of a shotcrete shell made from a facing wall without optical facing is known, which cladding comprises a plurality of facing walls arranged one above the other.
    The present invention is therefore based on the object of proposing a possibility with which such a panel can be produced better and faster.
    According to the invention, this object is achieved by a covering having the features of claim 1 and a method for producing a covering according to claim 7. Advantageous refinements can be found in the dependent claims referenced back.
    The cladding according to the invention has a reinforcement protruding above the wall shell from the facing wall, preferably reinforcement stirrups, which is connected via an in-situ concrete casting with a connecting iron protruding from the top of the wall shell, preferably reinforcement stirrups. In addition, reinforcing rods running in the longitudinal direction of the facing wall or the injection molded shell are provided in the cast-in-place concrete to connect the reinforcement protruding from the injection molded shell and the facing wall. This securely attaches the attachment wall and, with the appropriate facing on the front, the visible side, offers a visually appealing image.
    Advantageously, the cladding according to the invention is arranged on a foundation connected to the wall shell via a reinforcement. The height of the foundation is expediently designed in such a way that the upper edge of the facing wall with its maximum transport dimensions exceeds the upper edge of the wall shell by a sufficient amount for the attachment of the facing wall to the wall shell. The foundation is usually arranged in cross section horizontally to the wall shell. Depending on the design and arrangement of the wall shell, the facing wall is with its underside perpendicular to its side surface or corresponding to the extent of the inclination of the facing wall. The foundation is connected via a reinforcement protruding from the front of the wall shell in the form of connecting iron, which is then connected in a known manner to a suitable longitudinal reinforcement before the foundation is poured with in-situ concrete.
    The foundation is expediently arranged on a blinding layer in order to ensure a good subsurface.
    According to a further embodiment of the cladding according to the invention, the attachment wall on the underside facing the foundation is connected to the foundation via at least two bolts, preferably stainless steel bolts. The bolts are preferably arranged in the area of the two ends of the attachment wall and protrude from the side facing the foundation, the underside. The bolts are arranged in the attachment wall in such a way that they protrude essentially perpendicular to the surface of the foundation. The connection can be made in such a way that the bolts are inserted into openings provided in the foundation when the attachment wall is erected and the openings are then filled with a special flow mortar.
    According to a further embodiment of the cladding, the distance from the facing wall to the wall shell is made by means of at least two support brackets. These are placed and fastened with one, preferably longer limb, on the wall shell, and fastened with the other, preferably shorter limb, adjacent to the side of the wall facing facing the facing. After erecting the curtain wall, this gives it a temporary strength and stability that prevents it from falling over. The final stable fastening and connection to the wall shell is achieved by adding in-situ concrete as described above.
    In a further advantageous embodiment there are adjustable formwork elements on the support angles, for example in the form of at least one shuttering board or suitable sufficiently stable covers to close the space underneath, formed by the distance between the attachment wall and the wall shell, in order to prevent that the subsequently poured in-situ concrete gets into the free space.
    According to the inventive method for producing a cladding for a wall shell, a wall shell is used with connecting irons protruding from the front in the foot area of the wall shell and connecting irons protruding from the top in the head area of the wall shell. In front of the foot area of the wall shell, a blinding layer and then a foundation in the area of the protruding connecting iron is poured from the wall shell made of in-situ concrete, with at least two openings being provided in the foundation on the upper side to accommodate bolts protruding from the underside of the facing wall. Subsequently or beforehand, at least two support brackets are attached to the upper side of the wall shell, preferably with the longer leg on the wall shell to adjust the distance between the facing wall and the wall shell. To produce the cladding, an attachment wall is also used which has at least two spaced-apart bolts protruding from the underside, and preferably in the area of the two ends, and with connecting reinforcement corresponding to the connecting iron protruding from the upper side of the wall shell on the rear side facing the wall shell is provided. The attachment wall is inserted with the bolts protruding on the underside into the corresponding openings provided in the foundation and placed on the foundation with a previously applied mortar bed and leaned against the support bracket. This defines the position and, if necessary, the inclination of the attachment wall and can now be attached by attaching the attachment wall to the support bracket. Next or last, the bolt-receiving openings are filled with a flowing mortar in order to firmly connect the facing wall to the foundation. To connect the facing wall in the area of the wall head with the wall shell, adjustable shuttering elements are placed on the support bracket to cover at least the free space between the facing wall and the wall shell, which are intended to prevent the in-situ concrete from penetrating into the free space. These are therefore preferably designed as a mechanically stable cover, for example in the form of a shuttering board, but can in principle, depending on the application, also be made of another material that fulfills the purpose, such as solid fabric, etc. Before or expediently afterwards, the connecting irons protruding from the top of the wall shell are provided with longitudinal reinforcement along the wall shell or the facing wall and a cladding is attached to the front. The area between the wall shell and the facing wall and provided with the connecting iron, connecting reinforcement and longitudinal reinforcement can then be filled with in-situ concrete. This completes the cladding and can now be adapted to the landscape, for example, by applying soil to the last concreted area for adaptation.
    According to a further embodiment of the method, a railing can be attached to the top of the attachment wall.
    With the cladding proposed according to the invention, it is thus possible to produce a wall shell on the construction site with very little expenditure of time, also in a visually appealing manner by means of a clad facing wall.
    The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the specified combination, but also in other combinations or on their own. All of the features and / or advantages arising from the claims, the description or the drawing, including structural details, spatial arrangement and method steps, can be essential to the invention both individually and in the various combinations. The figures show: FIG. 1 a basic sectional view of a shotcrete shell with cladding; FIG. 2 shows an enlarged sectional view of the base of the wall and FIG. 3 shows an enlarged view of the head of the wall.
    The cladding 1 shown in Figure 1 has a back-anchored shotcrete shell 2 for fastening terrain 4 and a facing wall 3 arranged in front of it, which runs parallel to the shotcrete shell 2 and is inclined accordingly. The facing wall 3 has a facing 10 with, for example, natural stones on its visible side. This attachment wall 3 is a prefabricated concrete wall produced in the factory. This stands on a foundation 6 and a blinding layer 7 underneath and is connected to the shotcrete shell 2 above the shotcrete shell 2 via an anchor made of in-situ concrete 8. The shotcrete shell 2 is provided with a reinforcement cage (not shown) and is also usually attached to the site 4 with soil nails 5. In this exemplary embodiment, terrain 9 is poured above the in-situ concrete 8 and covers the in-situ concrete 8. In the figures, not all the usual reinforcements but only the reinforcements essential for the invention are shown.
    In the figure 2, the wall foot of the cladding 1 is shown enlarged schematically in cross section. In the area of the foot, it shows a reinforcement 11 protruding from the front side 28 of the shotcrete shell 2 in the form of a reinforcement stirrup. This is connected in the foundation 6 with a conventional longitudinal reinforcement (not shown) running in the longitudinal direction of the shotcrete shell 2 or the facing wall 3. In addition, in the area of the foundation 6 there is also a drain pipe 12 for receiving liquids emerging from the shotcrete shell 2. In addition, openings 13 are provided in the foundation 6 in order to receive stainless steel bolts 17 which are firmly embedded in concrete in the attachment wall 3 and protrude from it. After the reinforcement 11, the opening 13 and the drain pipe 12 have been prepared, the foundation 6 is poured with in-situ concrete after shuttering. As can be seen from the figure, there is a thin mortar bed of approx. 2 cm on top 15 on which the attachment wall 3 is set up. The opening 13 is filled with a flow mortar to ensure a firm connection of the bolt to the foundation. This is done via filling channels, not shown in the figure, which are still accessible after the attachment wall 3 has been erected. The stainless steel bolt 17 protrudes essentially perpendicularly into the opening 13 in the foundation 6 and thus protrudes from the correspondingly inclined underside of the attachment wall 3 at the angle of inclination of the attachment wall 3.
    Figure 3 shows the wall head schematically in cross section with protruding from the top 19 of the shotcrete shell 2 and connected to the reinforcement cage inside the shotcrete shell 2 connecting iron 18, which with the connection reinforcement 22, which protrudes perpendicularly from the back 25 of the facing wall 3, is connected via a conventional longitudinal reinforcement, not shown. On the upper side 19 of the shotcrete shell 2, support brackets 20 are fastened by means of screws 21, which serve as spacers for the attachment wall 3. In this exemplary embodiment, the bearing brackets 20 are connected with the longer leg on the shotcrete shell 2 and with the short leg via screws 21 'with the facing wall 3. Depending on the length, one or more shuttering boards 24 are located on the support bracket 20 as adaptable shuttering elements, which cover the free space 26 between the shotcrete shell 2 and the facing wall 3 from above, so that this area can be filled with in-situ concrete 8. The facing wall 3 is thus securely connected to the shotcrete shell 2. The in-situ concrete 8 can be piled up with terrain 9. In the exemplary embodiment, a handrail 23 is also attached to the top of the attachment wall 3, for example.
