Description

The present invention relates to a molded block (1) comprising a concrete body (2), an adhesive layer (3) and an artificial turf element (4); Traffic areas comprising a plurality of such stones, methods for producing these blocks and traffic areas and the use of such blocks and traffic areas.

Various shaped stones containing artificial turf elements are already known. WO2008 / 088919 and WO2008 / 039782 reveal a molded body with specific body and artificial turf. In the moldings disclosed therein, the synthetic turf element completely covers its surface. Traffic surfaces consisting of these moldings are unsuitable for numerous applications due to their low stability and poor drainage properties.

An object of the present invention is therefore to provide improved molded bricks and traffic areas.

The above-outlined objects are achieved according to the independent claims. The dependent claims represent advantageous embodiments. Further advantageous embodiments are given in the description and the figures. The general, preferred and particularly preferred embodiments, ranges, etc. given in connection with the present invention may be combined with one another as desired. Likewise, individual definitions, embodiments, etc. may be omitted or not relevant.

The terms used in the present invention are used in a generally conventional manner known to those skilled in the art. Unless otherwise stated directly, the following terms have the meaning given here .

"Formstone" refers to a three-dimensional body which has at least two plane-parallel surfaces ("top surface (21)" and "Under surface" (22)) and so for the creation of traffic areas, especially trafficable traffic areas, is suitable. In addition to the surfaces mentioned, the shaped brick has further side surface (s) (23). If only one side surface is present, then the shaped block is essentially cylindrical. Typically, however, the shaped brick is substantially parallelepiped-shaped, ie there are pairs of two substantially plane-parallel side faces (23). Formstones are also referred to as "shaped bodies", "building blocks".
Furthermore, the molded block can have elements for connection to further shaped bricks ("toothings"). If the molded block has such fasteners, this is typically referred to as composite stone. The connecting elements are typically realized by the shape of the side surfaces. Unless the molded block has such elements, it is typically referred to as paving stone.

"Concrete" refers to a known building material, which is made of cement, aggregate, water and possibly additives by hardening. In the context of the present invention, the term encompasses all weight classes (light, normal, heavy concrete) and strengths). Furthermore, the term encompasses both closed-cell concrete (such as, for example, in the standards DIN EN 1338, DIN EN 206-1 / DIN 1045-2 ... described) and porous concrete (such as gas concrete, foam concrete, hspwerksporigen concrete).

"Adhesive" refers to materials which are adhesively bonded by surface adhesion and internal strength, i. Adhesion and cohesion forces, can connect. The term includes in particular organic adhesives.

"Artificial turf" refers to a plastic carpet known per se, which resembles a natural turf in terms of its texture and appearance; these are commercially available. Artificial grass is used, for example, on sports fields (such as hockey, football and golf courses) or on playgrounds. According to the invention, a tufted artificial turf comprising a base layer and a pile is preferred from a variety of filaments. Fiber structure, fiber density and pile height can vary within wide ranges. The turf filaments may, for example, consist of polypropylene, polyethylene or polyamide. The turf filaments may be straight and / or curled, furthermore they may be tuft-shaped. The tufts back (base layer) may be coated with latex and possibly additionally stabilized.

In a first aspect , the invention thus relates to a molded block (1) comprising (ie containing or consisting of) a concrete body (2), an adhesive layer (3) and an artificial turf element (4) in which (i) the base body is a Deck surface (21), a bottom surface (22) and one or more side surfaces (23), (ii) the top surface (21) has a recess and thus forms one or more edge surfaces (24) and a bottom surface (25); (iii) the bottom surface (25) is partially or completely provided with the adhesive layer (3); (iv) the artificial turf element (4) is applied to the adhesive layer (3), and the turf element (4) covers the entire bottom surface (25). This shaped block is suitable for the production of traffic areas (5) as explained below. On the one hand, such traffic areas show a positive, nature-like appearance and on the other hand are robust and permeable to water. The invention therefore also relates to the use of a molded block (1) according to the invention for producing a traffic area (5). This aspect of the invention will be explained in more detail below.

Molded stone (1): The molded brick (1) can have all the usual shapes for concrete blocks. In one embodiment, therefore, the invention relates to a shaped block as described herein in the form of a composite brick. The term composite stone is generally known and designates in particular such shaped blocks, which is provided on the side surfaces (23) with interlocking interlocking toothing areas. In a further embodiment, therefore, the invention relates to a shaped block as described herein in the form of a paving stone. The term paving stone is generally known and refers in particular to those shaped blocks which have two plane-parallel side faces (23). The term paving stone also includes paving blocks with cam system. Such cam composite systems serve as a displacement protection of traffic areas and are shown in the figures.
The dimensions of the molded block can vary within a wide range and are in a range as usual for previously known concrete blocks.
The total volume of the shaped brick is typically in the range 1.0-200 dm3, preferably in the range 2.0-75 dm3.

The top surface of the block is typically 0.02 - 1.0 m2, preferably 0.05 - 0.5 m2. Examples include 0.20m * 0.20m, 0.25m * 0.25m, 0.5m * 1.0m.
The height of the shaped block is typically in the range 0.05-0.25 m, preferably in the range 0.06-0.20 m. Examples include thicknesses of 6, 8, 12 and 15 cm.

Basic body (2): The basic body (2) of the molded block according to the invention consists of concrete. The term concrete is explained above; basically all concrete qualities are suitable. The skilled person is able to select concrete qualities that correspond to the intended use. Such concrete qualities are commercially available or can be prepared by known methods. It is an advantage of the present invention that the concrete qualities already known for concrete blocks can also be used for the inventive shaped blocks. This allows a simple and cost-effective conversion of production.
In an advantageous embodiment, the concrete is an open-pore concrete, in particular a hovwerksporiger concrete. Molded stones made from this concrete show particularly good drainage behavior.
In a further advantageous embodiment, the concrete is a closed-cell concrete, in particular a concrete which corresponds to the standard DIN EN 1338. Concrete blocks made from this concrete show particularly good abrasion and frost resistance. A possibly insufficient drainage behavior can be compensated by the design of the traffic area, as described below. In a further embodiment, the base body consists of a uniform type of concrete ("homogeneous basic body"). Alternatively, the base body may have a layered structure, ie consist of two or more layers of different concrete qualities. A layered construction may be advantageous for better combining various requirements such as abrasion resistance, stability / brittleness, drainage properties, frost resistance and the like. In an advantageous embodiment, the invention therefore relates to a shaped block as described here, characterized in that the main body of consists of a plurality of layers, preferably of a base layer of a first concrete and a facing layer of a second concrete. It is particularly favorable if the base layer consists of a coarse-grained, porous concrete (for example 0-12 mm grain size or 0-11 mm grain size) and the facing layer consists of a fine-grained, porous concrete (for example 1-5 mm grain size or 2-5 mm grain size). 4 mm grain size). The aforesaid "pedestal layer" is also referred to as "core concrete layer"; these terms are equivalent in the context of the present invention.

Recess of the top surface (21): The recess of the top surface may in principle assume different geometric shapes, ie square, rectangular, circular, kuzförmig etc. The recess may be designed so that an all-round peripheral edge surface (24) remains or that the edge surface of a or more interruptions, for example, two opposite interruptions.
In an advantageous embodiment, the top surface (21) has a trough-shaped depression and thus forms a peripheral edge surface (24) and a bottom surface (25). In this embodiment, the artificial turf element (4) on all sides of the main body (2) comprises. This embodiment has proven to be particularly robust and is therefore particularly suitable for traffic areas that are traveled by vehicles and / or in traffic areas which are inclined. In the case of a basic body with the dimension 0.25 m * 0.25 m, the depression is, for example, 0.17 m * 0.17 m. In an alternative embodiment, the cover surface (21) has a band-shaped recess and thus forms two mutually separate, mutually opposite edge surfaces (24) and a bottom surface (25). In this embodiment, the artificial turf element (4) is not covered on all sides by the main body (2), but on two edges the turf element (4) is openly accessible on the side. This embodiment has proved to be optically advantageous, since thus graphic laying patterns can be realized. This embodiment is particularly suitable for traffic areas, which have a lower stress.

In a further alternative embodiment, the recess of the top surface is divided into a plurality of individual depressions, for example 4, 9 or 16 depressions, which are separated from one another by webs.
The ratio cover surface (21): bottom surface (25) may vary within wide ranges, for example. 100: 90 to 100: 30, preferably 100: 80 to 100: 40 is located. The surface of the molded block is thus covered to 30-90%, preferably 40-80% of the artificial turf element (4). According to the invention, the depression is adapted to the height of the glued-in artificial turf element. It has proven to be advantageous if the upper edge of the artificial turf element (4) is flush with the edge surface (24) or extends beyond 2 cm beyond, preferably 0.5 - 1.5 cm beyond. Accordingly, the recess is typically 5-30 mm, preferably 6-10 mm, in particular 7 mm deep.

Adhesive (3): The purpose of the adhesive (3) is to produce a secure, durable and easy-to-manufacture connection between the artificial turf element (4) and the base body (2). The choice of a suitable adhesive depends on the material of the artificial turf (in particular the base layer (51)) and the concrete type of the base body (2). Suitable adhesives are known, commercially available and to be identified by the skilled person in simple experiments. In an advantageous embodiment, the adhesive (3) is a polymeric adhesive, preferably selected from the group comprising polyurethane-based adhesives and epoxy resin-based adhesives.
The adhesive can be applied selectively, partially or over the entire surface. In one embodiment, the invention relates to a molded block as described herein, in which said artificial turf element is adhesively bonded to the main body (2) over the entire surface or substantially over the entire surface. The thickness of the adhesive layer formed may vary, depending, inter alia, on the type of adhesive and the type of application. Typically, a layer thickness of the adhesive of <5 mm, preferably 0.1 to 3 mm results. In a further embodiment, the invention relates to a molded block as described herein, in which said artificial turf element is adhesively bonded at points or parts of the surface to the base body. This can be realized by applying adhesive dots or adhesive tape. The contact surface of the adhesive typically covers 5-50% of the base area (25). This embodiment leads to particularly favorable drainage behavior. This embodiment is preferred in connection with open-pored concrete.

Artificial grass element (4): Artificial turf elements are known per se and a special form of a tufted cut pile carpet, with an appearance that corresponds to natural turf. Accordingly, artificial turf elements have a base layer (51) and a tuft fabric (52).

The base layer (51) may consist of a variety of materials, for example natural or synthetic latex, such as styrene-butadiene latex, which may be carboxylated. Such materials may contain other additives, such as inorganic bases, surfactants, thickeners.
The basecoat typically has a fabric or nonwoven backing and a second backing in the form of a latex layer.
The base layer (51) may be perforated, for example, with 4, 9, 16 or 25 holes / m2 and 1-5 mm hole diameter. This embodiment is particularly advantageous in open-pored concrete. The perforation, especially in combination with open-pore concrete, improves the drainage properties of the molded block (1).

The cut tufted fabric (52) is typically in the form of geometrically arranged tufts. These turf filaments (52) may consist of all common materials, for example. Of polyolefins, in particular polypropylene. These materials may contain other additives, for example dyes / pigments and UV stabilizers. The length of the turf filaments can vary within a wide range, for example 10 to 30 mm, typically 15 to 20 mm, in particular 17 mm. The number of tufts can be in a wide range, for example 2500-40000 Tufts / m2, preferably 5500-22500, in particular 14500.

Artificial turf elements (4) may have a filling between the turf filaments (52), for example a filling of sand; however, preferably no filling is present.

In an advantageous embodiment, the artificial turf element (4) has a possibly perforated base layer (51); a plurality of turf filaments (52), which are optionally arranged in a tuft-shaped manner and possibly a filling. Particularly preferably, the artificial turf element (4) has a perforation and no filling.

In a further embodiment, the molded block according to the invention can have elements (i) for connection to further shaped bricks or (ii) for spacing of further shaped bricks ("serrations", "cam composite system").
The invention thus also relates to a shaped block as described here, which is provided on its narrow sides with interlocking meshing toothed areas. Such gearing areas are well known. The invention is not limited to specific gearing ranges; rather, they can be present in all common variants. This will ensure that a given shaped block fits into the gearing areas of adjacent shaped blocks.
The invention further relates to a shaped block as described herein, which is provided on its narrow sides with toothed areas which ensure a spaced installation, see Fig. 3 and 5 , Such gearing areas are well known. The invention is not limited to specific gearing ranges; rather, they can be present in all common variants. This ensures that a gap is formed between the shaped bricks (1), which can optionally be filled with connecting material (6). The use of bonding material leads to a stabilization of the molded block (1) in a traffic area (5).

In a second aspect , the invention relates to a method for producing a molded block as described herein. This aspect of the invention will be explained in more detail below.

In a preferred embodiment of the method, the recess is formed by means of a heated to 50 - 70 ° C pressure plate and with shaking.

In a further preferred embodiment of the method, the recess is formed by means of an unheated pressure plate and with shaking.

In a third aspect , the invention relates to a traffic area (5) comprising a multiplicity of shaped bricks (1) as described here and optionally connecting material (6). Advantageous embodiments and features of this aspect of the invention will be explained below.

The term traffic area is known per se and includes in particular the areas which are intended for traffic (in particular stationary traffic) and / or for public or private use. The term therefore includes exemplary parking for motor vehicles, commercial space, track beds, footpaths, public spaces, garage parking, terraces, stairs, roof areas.
Traffic areas are typically uncovered; therefore, a good drainage of rainwater is needed. With the inventive shaped bricks such traffic areas can be realized.
Traffic areas are typically oriented substantially horizontally. With the inventive shaped bricks, however, traffic areas with a gradient / slope of up to 20%, preferably 0-7%, particularly preferably up to 0-2% can be realized.

Traffic areas may contain connection material in addition to the molded blocks according to the invention. Such compound material forms vertical joints between the stones. The term "bonding material" (or the equivalent term "jointing material") is well known and includes such materials that fill the space between the molding stones. Suitable joint material is known in the art and includes in particular gravel, sand and grit. As a connecting material is, for example, grit / sand 0-4 mm, chippings 1-3 mm or chippings 2-4 mm suitable. Thus, the invention relates to traffic areas, in particular accessible and / or traffic-accessible traffic areas, comprising a plurality of shaped bricks as described herein and possibly connecting material. The shaped blocks are arranged in such a traffic area so that the side surfaces are in contact with each other, either directly or via a possibly present connection material.
In one embodiment, the invention relates to a traffic area (5) as described herein, wherein the base body (2) of the stones (1) consists of haufwerksporigem concrete and wherein the traffic area contains no compound material. In this embodiment, a visually appealing traffic surface is realized, which nevertheless meets the requirements of water drainage. In a further embodiment, the invention relates to a traffic area (5) as described here, wherein the base body (2) of the molded blocks (1) consists of closed-cell concrete and wherein the traffic area contains a gravel bed as a connecting material. In this embodiment, a traffic area is realized, which is particularly robust and meets the requirements of water drainage and frost resistance.

The traffic areas (5) according to the invention can be created exclusively or partly from the molded bricks according to the invention. The molded blocks of the invention are therefore suitable for partially or completely replacing classic shaped bricks in traffic areas. The invention therefore relates to traffic areas (5) comprising (containing or consisting of) a multiplicity of shaped bricks (1) as described here and optionally connecting material (6).
In one embodiment, the invention relates to a traffic area as described herein in which the shaped block is made of an open-pored concrete and no bonding material is used. Such traffic areas are particularly accessible but not passable.

In this embodiment, it is preferred if the shaped blocks (1) are provided with widened spacers, for example 3-20 mm.

In a fourth aspect , the invention relates to a method for producing a traffic area. As already explained in detail, the inventive molded block is suitable to replace already known conglomerates. The processing of the molded block according to the invention is carried out in analogy to generally known methods which are familiar to the person skilled in the art. The invention therefore relates to a method for producing a traffic area by laying the molded blocks described here on a bedding layer (7).

• ■ Bereitstellen einer Bettungsschicht (7) (insbesondere Kies/Splitt oder Sand/Splitt);
• ■ Bereitstellen und Ausrichten eines ersten Formsteines (1);
• ■ Bereitstellen und Ausrichten weiterer Formsteine (1) zur Erzeugung einer Fläche aus Formsteinen (entweder manuell stückweise oder maschinell lagenweise);
• ■ ggf. Füllen der Fugen (6) mit Verbindungsmaterial
• ■ ggf. Reinigen und Abrütteln der erstellten Fläche
• ■ ggf. nochmaligens Einwischen / Einkehren von Verbindungsmaterial in die erstellte Fläche.

The method according to the invention comprises in particular the successive steps mentioned below:

• ■ providing a bedding layer (7) (in particular gravel / grit or sand / grit);
• ■ providing and aligning a first molded block (1);
• ■ providing and aligning further shaped bricks (1) to create an area of molded bricks (either manually by piece or mechanically by layer);
• ■ If necessary, fill the joints (6) with connecting material
• ■ If necessary, clean and shake the created surface
• ■ If necessary, wipe in / insert connection material into the created surface.

Accordingly, according to the present method, the inventive shaped blocks are used instead of the known shaped blocks for the production of a traffic area. It is considered to be an advantage that no new methods or new devices have to be used on the construction site. The production of traffic areas can be done both manually and by machine.

The examples below serve to further illustrate the invention; they are not intended to limit the invention in any way.

Example 1: Making a molded block

Production of the main body: Hovwerksporige concrete (Cement CEM I, Fa. Jura (Wildegg)) is filled on a commercial Brettfertiger / stone production plant in a mold (25 * 25 cm, height 8 cm); a depression (17.6 * 17.6 cm, depth 7 mm) is pressed in by means of a plate and then dried.
Production of the molded block: PU adhesive (BM Steintech / (Hünenberg, ZG)) is applied in the recess of the prepared base body at a distance of 10 mm to the edge and crosswise. An artificial turf area (Namgrass) becomes
glued by pressing at 8-9 bar. The resulting molded blocks can be processed as commercial shaped stones.

Example 2: Creating a traffic area

First of all, a suitcase / base course is produced in accordance with Swiss standard SN640 - 585 b. Then a bedding layer of chippings 3-6mm, thickness about 3 cm applied. Then the stones are laid according to Ex. 1 and grouted with chippings of 2-4 mm. The traffic area thus obtained resulted in a stable, pressure-resistant area. This area showed both good optical properties, even after intensive use, as well as a good seeping.
