Description

Corner set and arrangement with such

The present invention relates to a molded brick set, designed and arranged for fixing a built-in a road body built-in part, comprising a plurality of moldings adapted to surround the built-in part, wherein the molded blocks each have a the road surface forming the traffic layer and the traffic layer supporting base element. Furthermore, the invention relates to an arrangement comprising a built-in in a path body built-in.

Such molding sets and arrangements are used in the renovation or repair of built-in body parts built-in parts, such as the road repair. Increasing heavy goods traffic as well as increasing traffic density leads to high loads of built-in components on public roads. The load imposed by the vehicles on the built-in parts, the adjacent road surface and the ground regularly lead both to damage to the component itself and to the adjacent road surface.

To repair or refurbish such built-in parts and the adjacent path areas stone sets are known, which are arranged around the mounting part. Such sets of stones are known, for example, from document DE 82 16 196. The known inner contours of the stones of such a stone set are correspondingly adapted to the outer shape of the installation part located in the path body, so that they can be arranged around the installation part in order subsequently to form a substantially closed path body surface again after the repair measure has been carried out.

The disadvantage is that the known stone sets guide the forces acting on them due to the traffic load on the underlying components and these in turn are supported on the mounting part. Thus, the forces generated by the traffic load continue to act on the built-in part and finally lead to damage or partial destruction, so that after a correspondingly short service life, a renewed repair measure must be carried out. It is therefore an object of the present invention to provide a conveniently manageable molded stone set, which optimally protects the built-in component against harmful introduction of force due to traffic loads. Furthermore, the object is to provide a corresponding arrangement with such a mold block set.

The object is achieved by the aforementioned set of shaped stones by virtue of the fact that the base element has at least one projection projecting laterally beyond the traffic layer. On the one hand, this offers the advantage that the forces acting on the traffic load are now distributed over a standing area which is larger than the actual traffic area of each shaped block. As a result, the load acting on below the blocks arranged components surface load compared to the known solutions is significantly reduced and thus reliably protects the insert from harmful force. In addition, a further compression of the surrounding area is avoided, so subsidence is prevented. On the other hand, the supernatant serves as an investment element for adjacent conglomerates. When laying the stones results in a uniform joint spacing between the stones in this way automatically. The bricks are arranged during installation each supernatant lying supernatant and so creates a uniform joint pattern. The supernatant thus forms a pedestal base whose footprint is increased compared to the traffic area. In this way, the forces generated by traffic loads on the traffic layer are introduced via the widened base base in the underlying components and thus significantly reduces the surface load due to the floor space extension.

According to an expedient development of the invention, it is provided that the supernatant is formed by an edge element circulating at least essentially in the region of the base surface of the base element. In this way, the molded block is supported evenly on the underlying components and achieves a homogeneous surface load distribution. In addition, the edge element serves as an all-round spacer element for maintaining a defined joint distance to the respectively adjacent molded blocks.

A preferred embodiment of the invention is characterized in that the edge element is designed widening towards the stand surface side. To this In this way, the forces acting on the block by the traffic load are optimally distributed to the extended floor space.

An expedient embodiment of the invention is characterized in that the projection is formed by additionally arranged on the side surfaces of the base element web elements. The web elements fulfill an advantageous dual function. On the one hand, the web elements are set up as additional spacer elements that come into contact with the web elements of an adjacent molded block and thus always specify exactly the same joint width. On the other hand, the web elements serve as anchoring elements for an elastic sealing compound located in the joints.

According to a further preferred embodiment of the invention, the edge element is arranged without heels on the side surfaces of the base element. This offers the advantage that the transition between the base element and the edge element is continuous and thus formed edge-free, so that the introduced into the joints between the molded bricks potting compound remains permanently connected to the molded bricks under the influence of mechanical loads.

A further expedient embodiment of the invention is characterized in that the edge element has recesses on the surface side. This offers the advantage that the molded blocks, which are used for example in a concrete bed, are additionally secured against acting lateral forces. The hardened concrete forms corresponding concrete webs in the recesses, so that the molded block is supported against force components acting parallel to the path surface of the body. More preferably, the web elements are then arranged on the recesses.

According to an advantageous development, the blocks are made of concrete, plastic or a concrete-plastic mixture. The stones therefore have the appropriate robustness to carry the resulting traffic loads without damage. In particular, the execution of the stones made of plastic or a plastic concrete mixture represents an optimum of required material strength and simultaneous weight reduction.

In particular, the supernatant is advantageously at least 5 mm on all sides. This ensures that the footprint is increased at least to the extent that the surface load then acting on the underlying components is already reduced to such an extent. is decorated that there is no damage to said components and / or internals.

Furthermore, the object is achieved by the above-mentioned arrangement, wherein the installed in the body path built-in unit is surrounded with a surrounding set of decorative blocks with the aforementioned features and wherein the stones arranged under joint formation in each case by mutually adjacent contact of the respective supernatants in a surrounding layer and the joints are filled by means of a potting compound or liquid mortar. Advantageously, an elastic potting compound is used. The advantages mentioned above in connection with the molded bricks according to the invention also apply to the arrangement according to the invention, so that in order to avoid repetition, reference is also made to the aforementioned advantages with regard to the arrangement according to the invention. According to an advantageous embodiment of the arrangement, the mounting part is formed as a dome shaft and further comprises a Einstiegsdomausnehmung having foundation plate, wherein the foundation plate above the dome shaft is aligned with an entry dome of Domschachtes arranged with the Einstiegsdomausnehmung and a foundation base for the surrounding layer with the arranged thereon Forming stones. The foundation plate offers the advantage that the force effects, which are already greatly reduced by the shaped blocks according to the invention, are not introduced into the installation part by the traffic loads but are absorbed by the foundation plate and introduced into the subsoil. As a result, in particular the upper region of the shaft is protected from harmful effects of force.

Further preferred and / or useful features and embodiments of the invention will become apparent from the dependent claims and the description. Particularly preferred embodiments will be explained in more detail with reference to the accompanying drawings. In the drawing shows:

Fig. 1 is a perspective view of a molded block according to the invention, a perspective view of a arranged around a circular manhole dome stone set and

Fig. 3 is a longitudinal section of the arrangement according to the invention.

FIG. 1 shows by way of example a shaped block 10 of the molded brick set according to the invention. The molded brick set according to the invention is designed and installed for fastening a built-in part of a body 22 built-in part. For this purpose, the shaped stone set comprises a plurality of molded blocks 10 which are designed to surround the built-in part 22, as shown by way of example in FIG.

Each of the shaped blocks 10 has in each case one of the path body surface forming traffic layer 1 1 and a traffic layer 1 1 supporting base element 12. The traffic layer 1 1 is preferably adapted in color to the road surface of the path body and made of a suitably adapted color concrete mixture. In FIG. 1, by way of example, one of the shaped bricks 10 is shown as corner edge brick. However, the shaped stone set also comprises formed as center stones form stones 10, which - as shown in Figure 2 can be seen - are each arranged between the form of corner stones 10 formed blocks. Alternatively, the mold set includes rectangular shaped blocks 10, for example, for the enclosure of rectangular shaft domes.

The base element 12 has at least one traffic layer 1 1 laterally projecting overhang 13. In other words, the supernatant 13 forms a base base 16, whose base surface 14 is enlarged relative to the traffic surface 15. In this way, the forces generated by traffic loads on the traffic layer 1 1 are introduced via the widened base base 16 in the underlying components and thus significantly reduces the surface load due to the floor space extension.

The projection 13 is preferably formed by an edge element 17 which revolves at least substantially in the area of the base 14 of the base element 12. The edge element 17 is, as shown in the drawing, preferably arranged only partially circumferential. Optionally, the edge element 17 is designed to be continuous all round. According to an advantageous development of the invention, the edge element 17 is designed to widen the base side towards widening. In other words, the transition between the base element 12 and the edge element 17 is slidable, ie that the material thickness of the edge element 7 continuously increases starting from the base element 12 in the direction of the base surface 14, so that the projection 13 widens towards the base surface 14.

Preferably, the overhang 3 is additionally formed by web elements 19 arranged on the side surfaces 18 of the base element 12. The web elements 19 preferably have a thickness which corresponds to the greatest material thickness of the edge element 17. In this way, the web elements 19 with the edge element 17 form a plane projection surface. The web elements 19 thus form, together with the edge element 17, a contact surface against which the respective next shaped block 10 is placed under adjacent contact, so that the joint width between the shaped blocks 10 is predetermined by the material thickness of the web elements 19 and the largest material thickness of the edge element 17. Alternatively, the web elements 19 may also have a lower material thickness than the maximum material thickness of the edge element 17.

Advantageously, the edge element 17 is arranged without heels on the side surfaces 18 of the base element 12. This results in a continuous transition region 20 between the side surfaces 18 and the edge element 17. The transition region 20 is further preferably convex or concave, for example, grooved, formed. Alternatively, the transition region 20 may be configured a concavo-convex or convex-concave.

In particular, the edge element 17 has recesses 21 on the surface side. The recesses 21 are preferably - as shown in the drawing - set up trapezoidal and widening towards the base 14. The recesses 21 may be arranged on all sides, or be present only on some sides of the molded block 10. The web elements 19 preferably adjoin the recesses 21. D. h., The recesses 21 are arranged at those positions at which one of the web elements 19 is arranged on the respective side surface 18.

Advantageously, the blocks 10 are made of concrete, plastic or a concrete-plastic mixture. The shaped blocks 10 are preferably produced in one piece by casting. Preferably, the supernatant 13 is on all sides at least 5 mm. The largest material thickness of the edge element 17 is therefore also at least 5 mm. In this way, on the one hand, it is ensured that the standing surface 14 is correspondingly enlarged with respect to the traffic surface 15, so that the supporting surface load acting in the floor area area is reduced correspondingly to the traffic load acting on the traffic area 15. On the other hand, a minimum joint width between the individual shaped bricks 10 of the shaped stone set according to the invention is predetermined. FIG. 3 shows a longitudinal section of an exemplary embodiment of the arrangement according to the invention. The arrangement comprises the incorporated in the body body fittings 22, z. B. as shown in Figure 3, in the form of a shaft 23. To the built-in part 22 and the shaft 23 of the previously described shape stone set is arranged. As shown in FIG. 2, the conglomerates 10 are arranged under joint formation in each case lying in contact with the respective projections 13 in a surrounding layer 24 and the joints 25 are filled by means of a potting compound (not shown in the drawing). Alternatively, the joints 25 are filled with liquid mortar, preferably with early-strength plastic mortar. In FIG. 3, by way of example, a shaft 23 with a conical shaft ring 26 resting on a cylindrical shaft ring 27 is shown. However, the present invention is not limited solely to the shaft geometry shown, but in principle suitable for any shaft geometry, that is, for example, for shafts with rectangular, square or oval cross-section.

The surrounding layer 24 is preferably formed of concrete, gravel, granules, recycled material or an elastic mass. The conglomerates 10 close this surrounding layer 24 to the traffic surface and surrounding the manhole frame 28 as described above to form a uniform joint pattern.

Preferably, the mounting part 22 or the shaft 23 is designed as a dome shaft. This has a Einstiegsdomausnehmung 29, which is bounded by the manhole frame 28. Above the dome shaft or the shaft 23, ie in the region of the shaft mouth 30, a foundation plate 31 is arranged. This foundation plate 31 is aligned under alignment of a boarding dome 32 of the Domschachtes or shaft 23 arranged with the Einstiegsdomausnehmung 29. The foundation plate forms a foundation base for the surrounding layer 24 with the molded blocks 10 arranged thereon. As in FIG. 3, the manhole rings 26, 27 are laterally surrounded by compacted sand 33 on which the surrounding layer 24 is supported. At least one base plate 34 or a plurality of base plates 34 is preferably arranged on the foundation plate 31. Optionally, one or more bearing rings 35 are arranged above the base plate. Foundation plate 31, base plate 34 and the support rings 35 are optionally connected to each other by means of elastic joints 36. Alternatively, the foundation plate 31, the base plate 34 and the bearing rings 35 are connected by means of mortar joints. The base plate (s) 34 is disposed in the region of the shaft opening 30 and is supported on the foundation plate 31, so that forces acting on them are introduced by traffic loads in the foundation plate 31.
