Description

The invention is based on a paving in a bound pavement construction according to the preamble of claim 1 and a paving in a bound paving construction according to the preamble of claim 10.

In the case of a process known from ZTV Wegebau, DNV instruction sheet paving and slab ceilings for traffic and walked areas in unbound and bound design as well as in mixed construction methods or from ATV DIN 18318, FGSV 618/2, M FP for the new production of a pavement in bound paving Construction method, paving stones are placed on a bed in the form of a drainage mortar (water-permeable cement mortar) using an adhesion promoter and grouted with joint mortar. Before the grout hardens, the top of the paving stones and the grout surfaces of the grout applied in the joints are washed wet with water using a sponge cleaning machine or a water jet. This creates a deepening of the joint between the paving stones, i.e. the joint mortar surfaces of the joint mortar introduced into the joints are not in one plane with the top of the paving stones. Since washing off occurs before the grout hardens, the grout surfaces will water down. The grout depressions and watering down of the grout surfaces have some disadvantages.

On the one hand, dirt and dust are deposited in the grooves of the joints, which leads to an unfavorable appearance of the pavement and, when driven over by vehicles, to undesirable swirling up of fine dust. Furthermore, the acoustic properties of a pavement made with joint depressions are unfavorable. Last but not least, water containing de-icing salt can be deposited in the grooves of the joint and then damage the grout over time.

In contrast, the present invention is based on the object of further developing the new production of a pavement in a bound pavement construction in such a way that the disadvantages described above are avoided.

According to the invention, this object is achieved by the features of claim 1 and claim 10.

The invention is based on a paving in a bound pavement construction as a new production, in which

1. a) a bedding is applied to a subsurface,
2. b) paving stones each with a top surface, a base surface and a number of side surfaces are laid with their base surface on the bedding with the formation of joints, in particular to form a paving bond by means of an adhesion promoter, and
3. c) the joints are at least partially jointed with joint mortar, the free joint mortar surfaces of the joint mortar introduced into the joints being parallel to the top surfaces of the paving stones, and where
4. d) the paving stones of the paving bandage have a flat top surface.

The term “subsurface” should also include, for example, a substructure, a superstructure, a concrete ceiling, a drainage mat or the like. A top surface of a paving stone is therefore understood to be the free and upward-facing outer surface of a paving stone.

A bonded paving method should be understood to mean a method of construction in which the joints between the paving stones are bonded and, optionally, the bedding is also bonded, i.e. a hardening mortar is used in each case. Bonded paving should also be understood to mean a construction in which the joints between the paving stones are bonded and the bedding is unbound (mixed construction).

According to the invention it is provided in the pavement that

• e) the joints have been grouted with grout and at least the grout surfaces have been stripped using a stripping tool in such a way that, after the grout has hardened, the grout surfaces are arranged in a plane with the flat cover sides, in particular of adjacent paving stones.

The joints are therefore somewhat overfilled vertically, i.e. that initially soft grout protrudes vertically from the joints, which is then pulled off, i.e. removed, by the pulling tool so that a flat surface is created together with the cover sides of the paving stones. Peeling off at least the joint mortar surfaces means that the joint mortar protruding vertically in the joints is peeled off and removed with the peeling tool. It is of course inevitable that the top sides of the paving stones are also removed.

The removal of the grout surfaces and the cover sides of the paving stones by means of the The pulling tool is only used as long as the grout is still soft and not hardened. Therefore, what has been said also relates to a new production of the paving. A rubber scraper is preferably used as a pulling tool, for example, which is pulled over the grout surfaces.

2. b) Pflastersteine mit je einer Deckfläche, je einer Grundfläche und je einer Anzahl von Seitenflächen unter Ausbildung von Fugen, insbesondere zu einem Pflasterverband und insbesondere mittels eines Haftvermittlers, mit ihrer Grundfläche auf der Bettung verlegt sind, und

5. e) die Fugenmörteloberflächen des ausgehärteten und in den Fugen verfugten Fugenmörtels in einer Ebene mit den ebenen Deckflächen der Pflastersteine angeordnet sind.

The invention is also based on a paving in a bound pavement construction, in which

1. a) a bedding is applied to a subsurface,
2. b) paving stones each with a top surface, a base surface and a number of side surfaces each with the formation of joints, in particular to form a paving bond and in particular by means of an adhesion promoter, are laid with their base surface on the bedding, and
3. c) the joints are at least partially jointed with joint mortar, free joint mortar surfaces of the joint mortar introduced into the joints being arranged parallel to the top surface of the paving stones, and where
4. d) the paving stones of the paving bandage have a flat top surface. According to the invention, it is provided in the pavement in a bound pavement construction that
5. e) the grout surfaces of the hardened grout that has been grouted in the joints are arranged in one plane with the flat top surfaces of the paving stones.

This state is achieved in that the joints are grouted with grout and the grout surfaces are peeled off by means of a pulling tool in such a way that after the grout has hardened, the grout surfaces are arranged coplanar with the flat cover sides of adjacent paving stones, without any grooves in the grout surfaces in relation to the grout surfaces Cover pages are created. The grout surfaces then form a common plane together with the cover sides of the paving stones.

This results in some advantages over the prior art mentioned at the beginning. On the one hand, there is an increase in the frost / de-icing salt resistance of the pavement in the bound pavement construction, because no cement paste was washed out and, due to the lack of joint depressions, de-icing salt can no longer be deposited there and damage the grout. On the other hand, there is also a higher joint strength because the grout surfaces are flush with the stone edges of the paving stones. Last but not least, this also results in an improved evenness of the pavement, which has a positive effect on the one hand on the comfort when walking and driving vehicles and on the other hand also on the acoustics, because the previously usual edges on the joint depressions, which when driven over by a Excite the vehicle to vibrate.

The measures listed in the subclaims allow advantageous developments and improvements of the first aspect of the invention.

It is preferred not to wash off the cover sides of the paving stones or the grout surfaces before the joint mortar has hardened. This prevents water from penetrating the joint mortar, which is still soft because it has not yet hardened, and diluting or watering it down. Furthermore, this also prevents unavoidable joint depressions from forming during washing, which bring about the disadvantages already described above.

According to a particularly preferred further development of the paving, the cover sides of the paving stones and the joint mortar surfaces are processed together in a surface treatment process in particular immediately after the joint mortar has hardened in such a way that the top sides of the paving stones and the joint mortar surfaces have a common structure and / or a common surface roughness. In other words, a substantially identical surface roughness or roughness depth of the cover surfaces of the paving stones and the grout surfaces is achieved. After the grout has hardened or immediately after the grout has hardened, in this context the surface treatment process only affects the already hard grout surfaces, without any deeper layers of the hardened grout being affected. The surface treatment process therefore explicitly represents a process step in the production of the new pavement and is not carried out on an existing pavement, for example, in order to subsequently roughen the surfaces of paving stones that have been smoothed through wear, so that vehicles or pedestrians do not slip. The paving is therefore completely produced in the context of a new production, starting with the application of the bedding up to the aforementioned surface treatment process. The construction site set up for this purpose remains in place until the surface treatment process has been completed. “Immediately” after the grout has hardened means that the surface treatment process takes place as part of this new production.

The surface treatment process is therefore preferably abrasive, that is to say it removes material, in that the surface treatment process removes material both from the hardened grout surfaces and from the top surfaces of the paving stones. Depending on the surface structure of a rotating tool, for example a grinding tool, by which the surface treatment process is carried out, the surface structure of the tool can therefore be transferred to the grout surfaces and the cover surfaces of the paving stones.

The surface treatment process has the advantage that small vertical protrusions of neighboring paving stones, so-called over-teeth, can be removed by working on the top surfaces. Furthermore, this results in a higher slip resistance because the structure and / or the roughness of the surface of the pavement can be variably adapted in this regard. In addition, this preferred procedure allows a variable adaptation to acoustic specifications for noise reduction.

The surface treatment process can, for example, have at least one of the surface treatment processes mentioned below: blasting, shot peening, sandblasting, flame blasting, sticking, grinding, this list not being exhaustive. Consequently, any surface treatment operation can be carried out for the surface treatment operation, with which a desired common structure and / or a common surface roughness of the top surface of the paving stones and the grout surfaces is created.

The top surfaces of the paving stones and the grout surfaces of the finished paving therefore preferably have a common structure and / or a common surface roughness.

According to a preferred development, the surface treatment process takes place in such a way that the cover surfaces of the paving stones and the grout surfaces receive or have a predetermined common structure and / or a predetermined common surface roughness. Predefined in this context means that a predetermined common structure and / or a predetermined common surface roughness of the cover surfaces of the paving stones and the grout surfaces is achieved by the surface treatment, which results in the advantages already mentioned above.

The preferred peeling means that the grout surfaces are arranged in a plane with the flat top surfaces of adjacent paving stones after the grout has hardened. The surface treatment process, which is then preferably used after the joint mortar has hardened, then ensures a common structure and / or surface roughness on the surface of the pavement.

Particularly preferred paving stones are used as paving stones from a block that are sawed on all sides or split and only sawn on the top side, which are also unbevelled, i.e. without bevel, in particular on the edges delimiting the cover surfaces or on all edges. The latter design has the advantage that incorrect (twisted) installation of the paving stones will not have any consequences. On the one hand, this results in a higher joint strength, since the joint ends at the (sharp) edges with unbevelled paving stone edges and therefore there is a greater vertical extent of the joint mortar compared to chamfered paving stone edges. Furthermore, the formation of joint depressions in the area of chamfers is avoided in the case of unbevelled paving stone edges. In the finished paving, the paving stones are therefore unbevelled, at least in the area of the top surfaces.

If the paving stones are paving stones sawn from a (granite) block, the top surface in particular already has a rough structure caused by the sawing process, which can then be adapted to a desired structure and / or surface roughness by the surface processing process. In contrast, the side surfaces and the base of the paving stones can remain in the rough structure caused by the sawing process.

According to a further development of the pavement, the bedding is produced, for example, by a drainage mortar and the adhesion promoter by adhesive slurry.

At least some of the paving stones are preferably made of natural stones, clinker, concrete, or artificial stones such as cinder blocks, synthetic resin stones, ceramics, etc. In this respect, the term “paving” or “paving” construction or “paving stone” is to be understood broadly also includes, for example, a tile covering using tiles made of the above materials.

The invention also relates to a road, a bicycle path, a sidewalk, a parking space or a parking lot, which comprises a paving or paving as described above.

The paving according to the invention can be the paving of the street, des Represent the cycle path, sidewalk, parking space or parking lot in full or just a section or part of it.

Advantageous further developments of the invention emerge from the claims for protection, the description and the drawings. The advantages of features and of combinations of several features mentioned in the introduction to the description are merely exemplary and can come into effect alternatively or cumulatively without the advantages necessarily having to be achieved by embodiments according to the invention.

Further features can be found in the drawings - in particular the geometries shown and the relative dimensions of several components to one another and their relative arrangement and operative connection. The combination of features of different embodiments of the invention or of features of different protection claims is also possible in a way deviating from the selected back-references of the protection claims and is hereby suggested. This also applies to features that are shown in separate drawings or mentioned in their description. These features can also be combined with features of different protection claims. Features listed in the claims for further embodiments of the invention can also be omitted.

An exemplary embodiment of the invention is shown below in the drawing and explained in more detail in the description below. In the drawing, the single figure shows a highly schematic cross-sectional representation of a paving stone covering according to a preferred embodiment of the invention, which has been produced according to a preferred embodiment of the invention.

Description of the embodiment

In the figure is a pavement 1 shown in bound pavement construction, which is here, for example, part of a road used by vehicles.

With the pavement 1 is a bedding 2 on an underground 4th applied and paving stones 16 each with a top surface 6th , each with a base area 8th and here, for example, four side surfaces 10 with the formation of joints 12th to a plaster bandage by means of an adhesion promoter 14th with their base 8th on the bedding 2 relocated. The bedding 2 is formed for example by a drainage mortar and the adhesion promoter 14th through adhesive sludge. The cobblestones 16 consist, for example, of natural stone, in particular of granite, and have at least the top surfaces 6th unbevelled stone edges. The paving stones are preferred here 16 for example, paving stones sawn from a block of natural stone.

The joint 12th are, for example, completely covered with grout 18th grouted, being grout surfaces 20th des in the joints 12th applied grout 18th to the top surface 6th the cobblestones 16 point. Furthermore, the cobblestones show 16 of the plaster bandage a flat top surface 6th on. Here are the grout surfaces 20th of the hardened grout 18th in one plane with the flat top surfaces 6th the cobblestones 16 arranged.

The top surfaces 6th the cobblestones 16 and the grout surfaces 20th preferably have a common structure and a common surface roughness.

The pavement shown in the figure 1 is preferably re-manufactured by the process described below.

First is the bedding 2 on the ground 4th applied. Then the cobblestones 16 which has a flat top surface 6th have, with the formation of joints 12th between the side faces 10 to the plaster bandage by means of the adhesion promoter 14th with their base 8th on the bedding 2 relocated. Then the joints 12th completely with grout 18th grouted, the grout surfaces 20th des in the joints 12th applied grout 18th to the top surface 6th the cobblestones 16 point. The joint 12th are doing so with grout 18th grouted and in the still soft state of the grout 18th the grout surfaces 20th by means of a pulling tool, for example with the help of a rubber or foam scraper, pulled off in such a way that the grout surfaces 20th after the grout has hardened 18th in a plane 22 with the flat top surfaces 6th the cobblestones 16 are arranged.

The joint 12th are therefore preferred with grout 18th a bit overcrowded vertically, ie that initially soft grout 18th out of joint 12th swells or protrudes vertically, which is then pulled off by the pulling tool, ie removed, so together with the cover surfaces 6th the cobblestones 16 a flat surface is created. Because the shrinkage of the grout 18th is very slight during the hardening process, the flat surface remains even after hardening. Peeling off at least the grout surfaces means that in the joints 12th vertically protruding grout 18th is peeled off with the pulling tool and removed. It is of course inevitable that the top surfaces 6th the cobblestones 16 must also be peeled off, ie that there is excess grout 18th from the deck surfaces 6th is deducted. This will also remove the grout 18th dirty deck surfaces 6th the cobblestones 16 pre-cleaned.

Peeling off the grout surfaces 20th and the top surfaces 6th the cobblestones 16 by means of the pulling tool takes place only as long as the grout 18th is still soft and not hardened.

It is preferred before the grout has hardened 18th in the joints 12th no washing off of the top surfaces 6th the paving stones and the grout surfaces 20th carried out. This prevents water from getting into the grout, which is still soft because it has not yet hardened 18th penetrates and dilutes or dilutes it. This also prevents grout depressions from forming when the grout surfaces 20th to be washed off.

According to a particularly preferred embodiment, the top surfaces 6th the cobblestones 16 and the grout surfaces 20th machined together in a surface treatment process in such a way that the top surfaces 6th the cobblestones 16 and the grout surfaces 20th have a common structure and / or a common surface roughness. In other words, a substantially identical surface roughness or roughness of the cover surfaces can thereby be achieved 6th the cobblestones 16 and the grout surfaces 20th of the hardened grout 18th be achieved.

The surface treatment process can, for example, have at least one of the surface treatment processes mentioned below: blasting, shot peening, sandblasting, flame blasting, sticking, grinding, this list not being exhaustive. Any surface treatment operation with which a desired common structure and / or a common surface roughness of the cover surfaces can therefore be carried out for the surface treatment operation 6th the cobblestones 16 and the grout surfaces 20th is achievable.

In particular, the surface treatment process can be carried out using suitable tools in such a way that the top surfaces 6th the cobblestones 16 and the grout surfaces 20th obtain or have a predetermined common structure and / or a predetermined common surface roughness.

The top surfaces 6th the cobblestones 16 and the grout surfaces 20th of the finished paving 1 therefore preferably have a common structure and / or a common surface roughness.
