Abstract
The invention relates to a molded block (20) of concrete. The molded block (20) is suitable for building a supporting wall (21) which is inclined to the vertical against an earth backfill (22) and in which the individual molded blocks (20) are arranged one above the other in layers.
The molded block (20) is formed as a cavity block in such a way that, with the molded blocks (20) arranged offset in relation to one another in layers in a supporting wall (21), the load-transferring regions of the molded blocks (20) arranged above or below one another are arranged essentially in line in the load-transferring direction.
This makes it possible for supporting walls to be built from molded blocks with considerably larger apertures than in the prior art, with the same or greater load-bearing capacity.

The PCT applicant is SF-Kooperation GmbH Beton-Konzepte, a corporation of Germany, having a business address of Bremerhavener Heerstrasse 10, 28717, Bremen, Germany.
- 1. Technical Field
- The invention relates to a molded block of concrete for building a supporting wall which is in particular inclined to the vertical against an earth backfill and in which the individual molded blocks are arranged one above the other in layers. Furthermore, the invention relates to a corresponding supporting wall comprising such molded blocks.
- 2. Prior Art
- Such molded blocks or supporting walls are known in various embodiments in practice. To be mentioned by way of example is EP 0 191 908 B1, originating from the applicant.
- The molded blocks and supporting walls known from the prior art basically perform their purpose. However, laying is laborious, in particular with regard to the necessary anchoring measures to secure the supporting wall.
- Against this background, the invention is based on the object of further developing molded blocks and supporting walls of the type mentioned at the beginning.
- A molded block to achieve this object is a molded block of concrete for building a supporting wall which is in particular inclined to the vertical against an earth backfill and in which the individual molded blocks are arranged one above the other in layers, characterized in that the molded block is formed as a cavity block with at least one cavity or a vertically directed aperture, the, or essentially each, cavity or aperture being arranged in such a way that, with the molded blocks arranged offset in relation to one another in layers in a supporting wall, preferably the essentially load-transferring regions of the molded blocks arranged above or below one another are arranged essentially in line in the load-transferring direction. The fact that the molded block is formed as a cavity block with at least one cavity or a vertically directed aperture has the effect that the molded block has a lower weight than conventional molded blocks for building supporting walls. The molded block can consequently be laid more easily, in particular manually. Furthermore, it is provided that the, or essentially each, cavity or aperture is arranged in such a way that, with the molded blocks arranged offset in relation to one another in layers in a supporting wall, load-transferring regions of molded blocks arranged above or below one another are arranged essentially in line in the load-transferring direction. This configuration makes very large cavities or apertures possible, so that the molded blocks have a comparatively low weight. The applicant has recognized that, if the load-transferring regions are arranged in line in spite of the offset arrangement in layers, the entire load-transferring cross section can be used for dimensioning purposes, so that the remaining walls can be made relatively thin.
- In a preferred embodiment of the invention, it is provided that the molded block is trapezoidally formed in horizontal projection. The or each cavity may be formed continuously from an upper side to an underside of the molded block, so that vertically directed apertures are created. In a preferred embodiment of the invention, the molded block has three cavities or apertures, which are separated from one another by obliquely directed webs.
- Visible faces of the molded block preferably have a specially formed surface, for example a surface similar to natural stone.
- A further special feature comprises the formation of depressions intended for receiving connecting means that are envisaged when building special supporting walls.
- The supporting wall according to the invention is a supporting wall comprising molded blocks of concrete, which is preferably inclined to the vertical against an earth backfill and in which the individual molded blocks are arranged one above the other in layers, characterized in that the molded blocks according to the invention are used. The supporting wall thereby benefits from the advantages that can be achieved by using the molded blocks.
- In a preferred development of the invention, it is provided that the supporting wall comprises at least two walls, individual molded blocks of the two walls being connected to one another by connecting means. This results in a supporting wall which has a much greater static width and withstands correspondingly greater loading by the earth backfill.
- Preferred developments of the invention concern the type of connection of the two walls and the configuration of the connecting means. Depending on requirements, the molded blocks of each layer may be connected to one another, or else only the blocks of every second, third, etc. layer. The same applies to the arrangement in horizontal projection.
- The rear wall may have the same height, a smaller height or a greater height than the front wall, depending on requirements in terms of statics. A further special feature comprises that the molded blocks can not only be laid as straight walls but also make it possible to lay curved walls.

FIG. 12 shows an alternative laying patterns of the molded blocks according toFIG. 1 in horizontal projection. -
FIG. 13 shows an alternative laying patterns of the molded blocks according toFIG. 1 in horizontal projection. - Shown in the figures are on the one hand a molded
block 20 of concrete (FIGS. 1 to 5 ) and on the otherhand supporting walls 21 comprising such molded blocks (FIGS. 6 to 10 ).FIGS. 11 to 13 show laying variants of the moldedblock 20. The moldedblock 20 shown inFIGS. 1 to 5 is suitable for building walls of any type. The moldedblocks 20 can be laid without mortar, for example as a vertical wall or the like, or as a supportingwall 21 with an inclination against anearth backfill 22. - The molded
blocks 20 have in each case a number ofupright side walls upper side 25 andunderside 26. The moldedblocks 20 are essentially trapezoidally formed in horizontal projection. In this case, twoopposite side walls 24 are parallel to one another and twoopposite side walls 23 converge toward one another. - The molded
block 20 may be produced in conventional (concrete block) molds, so that theside walls blocks 20 may be produced in the molds with theunderside 26 facing upward, so that the upward-facingunderside 26 can be shaped or embossed by a die. - In the exemplary embodiment shown, it is provided that at least one of the two
parallel side walls 24, preferably at least thelonger side wall 24, is provided with a special structure, for example a structure similar to natural stone. To achieve this effect, the mold may be formed for example according to the applicant's DE 102 47 259 A. - The molded
block 20 is formed as a cavity block. In the exemplary embodiment shown, a total of three vertically directedapertures apertures upper side 25 to theunderside 26 of the moldedblock 20. Theapertures block 20. The base of thelargest aperture 27 runs parallel to theshorter side wall 24 and extends over virtually its entire width. The point of theaperture 27 lies approximately in the longitudinal center of thelonger side wall 24. The twoother apertures aperture 27. The bases of theapertures longer side wall 24. The points of theapertures shorter side face 24. Theapertures aperture 27. - The
apertures outer walls 30 in the region of theside walls inner webs 31, which run between thewalls 30 and separate theapertures webs 31 run in a way corresponding to the arrangement of theapertures shorter side wall 24 in the direction of the longitudinal center of thelonger side wall 24. The upper side and underside of thewebs 31 lie in the plane of theupper side 25 andunderside 26, respectively, of the moldedblock 20. - Also formed in the region of the
underside 26 of the moldedblock 20 aredepressions 32, which serve for receiving connectingmeans 33. Thedepressions 32 run parallel to theside walls 24 and are arranged at a distance from them. In cross section, thedepressions 32 are initially rectangularly formed, starting from theunderside 26, followed by a region converging toward theupper side 25. The maximum depth of thedepressions 32 is the same in each case. - The molded blocks 20 shown in
FIGS. 1 to 5 can be laid as a supportingwall 21 according toFIGS. 6 and 7 . Starting from afoundation 34 and asloping block 35, arranged on it, with a sloping upper side directed obliquely in cross section, the moldedblocks 20 are arranged one above the other in layers. On the side of the supportingwall 21 facing away from avisible side 36 is theearth backfill 22. Thefoundation 34 and some moldedblocks 20 are located underneath an adjoiningground level 37, which adjoins on the side of the supportingwall 21 facing away from theearth backfill 22. - As can be seen from
FIG. 7 , the moldedblocks 20 within a layer are always arranged in such a way that thelonger side walls 24 face thevisible side 36 of the supportingwall 21. In this way, a continuous supportingwall 21 in which the longer side walls are arranged in a plane is obtained in the region of the visible side. In a way corresponding to the trapezoidal shape of the moldedblocks 20, the side face of the supportingwall 21 facing away from thevisible side 36 has between neighboring moldedblocks 20clearances 38, which are triangular in horizontal projection and can be filled by theearth backfill 22. - As
FIG. 7 further reveals, the moldedblocks 20 are arranged offset in relation to one another in layers. InFIG. 7 , the molded blocks of an upper layer are identified by way of example by thedesignation 20, whereas the molded blocks of a lower layer are provided with thedesignation 20′. On account of the special cross-sectional shape of the moldedblocks blocks 20 chosen such that they are offset in relation to one another in layers, their load-transferring regions, i.e. in the present case thewalls 30 andwebs 31, are arranged in line one above the other. That is to say that, in the present case, the remaining cross-sectional area can be used completely for load transfer, so that the thickness of thewalls 30 andwebs 31 can be minimized considerably. The arrangement in the present case is chosen such that thegreater aperture 27 of a moldedblock 20 is respectively located above aclearance 38 between two moldedblocks 20′ and asmaller aperture 28 of a moldedblock 20 is located above asmaller aperture 29 of the moldedblock 20′ lying thereunder. - It is not imperative for the load-transferring regions to be arranged completely in line one above the other. It is also conceivable that this applies for example only to part of the
walls 30 andwebs 31. In this case, there is just a reduction in the cross-sectional area of the moldedblock 20 that can be used for load transfer, so that the load-transferring regions may have to be made with a greater wall thickness, or only lower loads can be accepted. - The supporting
wall 21 shown inFIGS. 8 and 9 represents a special case, namely a supportingwall 21 comprising twowalls blocks 20 which are connected to one another by connectingmeans 33. Thefront wall 39 is formed exactly in the same way as the supportingwall 21 described above, according toFIGS. 6 and 7 . Therear wall 40 is likewise correspondingly constructed, but aligned in such a way that thelonger side wall 24 is facing outward. The molded blocks 20 of the two mutuallyparallel walls shorter side walls 24 face one another. Correspondingly, theclearances 38 are also directed toward the “inside” of the supportingwall 21. In the exemplary embodiment shown, therear wall 40 has a smaller height than thefront wall 39 for reasons of statics. - To connect the two
walls blocks 20 of the twowalls depressions 32 by connectingmeans 33. In this case, a connectingmeans 33 respectively connects two opposing molded blocks 20. In the present case, the connectingmeans 33 is led through thedepressions 32 of the opposing moldedblocks 20 in the manner of a loop. It is not imperative for the connecting means 33 to be formed as a closed band. It may also be that the connectingmeans 33 are formed as two essentially C-shaped, clasp-like formations, which engage in thedepressions 32 from both sides. - In the present case, the connecting
means 33 are placed in thedepressions 32, so that a jointed connection of the opposing moldedblocks 20 is created. From a statics viewpoint, this creates a supportingwall 21 with a greater width, which can accept greater loads (in particular tilting moments) than conventional, single-skin supporting walls 21. The covering of therear wall 40 by theearth backfill 22 also contributes to this. - The supporting
wall 21 shown inFIG. 10 differs from the supportingwall 21 according toFIG. 8 in that therear wall 40 has a greater height. The height of therear wall 40 may be adapted to the requirements in terms of statics. - In principle, supporting
walls 21 which have more than twowalls visible side 36. - Furthermore, it is conceivable that an anchorage by the connecting
means 33 is not provided over the entire height of thewalls means 33 may additionally vary. Depending on requirements in terms of statics, every layer or every second layer may be connected by connectingmeans 33. Greater intervals are also conceivable. In the longitudinal direction of the wall, it is also not imperative for every moldedblock 20 to be connected to an opposing moldedblock 20 of anotherwall - As mentioned at the beginning, the molded
blocks 20 can be laid without mortar, so that the retention between the individual layers is obtained by the dead weight of the blocks and the covering by theearth backfill 22. Alternatively, positive or non-positive connections may of course also be provided between the moldedblocks 20 of neighboring layers. - The connecting means 33 provided here should be produced from a durable material that is fit for the intended purpose. Connecting means 33 made of plastic or (stainless) metal are conceivable for example.
-
FIGS. 11 to 13 show laying variants of the moldedblock 20 according to the invention. To be able to lay moldedblocks 20 as supportingwalls 21 which have a curved horizontal projection, it may be necessary to arrange neighboring moldedblocks 20 in a relative position such that they are turned by 180° in relation to one another. In this way it is possible for example to erect the supportingwall 21 shown inFIG. 11 , of an S-shaped form in horizontal projection. A special feature in this case also comprises that the neighboring moldedblocks 20 are respectively laid in such a way that the convergingside walls 23 of neighboring moldedblocks 20 lie against one another. -
FIG. 12 shows in the above sense a “corner formation” of a supportingwall 21, all the moldedblocks 20 in the corner region being laid with the same relative position andside walls 23 lying against one another. -
FIG. 13 shows a straight supportingwall 21 in which the relative position of neighboring moldedblocks 20 is respectively turned by 180° in relation to one another, so that in the region of thevisible side 36 of the supporting wall 21 ashort side wall 24 respectively follows along side wall 24. -
