Description

Technical Field

[0001] The invention relates to a belt fabric for a linear drain device, a linear drain system having the belt fabric, and the use of the belt fabric or the linear drain system for the installation of a linear drain device. Background Art

[0002] Linear drains are used to drain surface water, such as rainwater or sewage, from squares, forecourts, car parks, entrances, flat roofs, terraces, streets, other, in particular sealed surfaces and the like. For this purpose, the linear drain is introduced into the ground. The length of the linear drain extending in the longitudinal direction is greater, preferably a plurality of times greater, than the width of the linear drain perpendicular to the length of the linear drain. Thus, for surface drainage, surface water can be absorbed and discharged substantially linearly along the length of the linear drain. Thus, a linear drain differs, for example, from a point drain, such as a shaft drain, in which the surface water is absorbed substantially at a point or over a smaller surface, in particular a smaller length, than in a linear drain.

[0003] For this purpose, the linear drain can consist of at least one, preferably a plurality of individual elements (e.g. drain grooves) arranged one next to the other in the longitudinal direction, wherein each individual element can have a length of, for example, one meter. For example, the individual elements at the ends of the linear drain are cut to the desired length to obtain the desired overall length of the linear drain. The drain groove can be designed, for example, as a box groove with a grate guard or as a slot groove. Surface water can be received through one or more openings on the upper side of the linear drain and carried away by connection to a drainage system or an infiltration system.

[0004] The installation of a linear drainage system in the ground is usually carried out in two steps: First, the individual elements are introduced precisely to the prepared height on the prepared plane of the space, for example, by pouring concrete into the individual elements in their lower region or embedding them in sand. The space is then filled to the predetermined correct height with filling material, such as concrete, stone, gravel or paving stones. In particular, in the second step of filling the ground, it can happen that the filling material partially reaches the individual elements and from there can even reach the drainage system. This situation necessitates undesirable and expensive cleaning work on the individual elements, often even through the tips when concrete is used as filling material.

[0005] EP 3 929 360 A1 describes a shaft cladding system having a shaft cladding and a magnetic cladding for covering the side of the shaft cladding facing away from the shaft. The magnetic cladding is designed such that the dimensions of the magnetic cladding substantially correspond to the dimensions of the side of the magnetic cladding facing away from the shaft. EP 3 929 360 A1 therefore relates in particular to point drainage for surface drainage. Summary of the invention

[0006] Therefore, the object is to provide a belt fabric for a linear drain, or an improved or alternative linear drain system, or an improved or alternative application of a belt fabric or a linear drain system, by which the installation of the linear drain system is particularly simplified, in particular by being able to prevent or at least reduce the inflow of filling material through openings on the upper side of the linear drain.

[0007] This object is achieved by the use of a belt fabric according to claim 1, a linear drain system according to claim 10 and a belt fabric and / or a linear drain system according to claim 13. Improvements of the invention are given in the dependent claims. The use of a belt fabric or a linear drain system can also be further improved by the features of the belt fabric and the linear drain system given below or in the dependent claims, and vice versa. The features of the belt fabric and the linear drain system can also be used in combination with one another for further improvements.

[0008] The tape fabric according to the present invention is suitable for use with a linear drain device extending a first length in a longitudinal direction and having one or more openings for receiving surface water. The tape fabric has a second length greater than the first length of the linear drain device and is designed to reversibly cover the one or more openings. The tape fabric includes at least one magnetic layer.

[0009] Preferably, the magnetic layer is designed to generate a magnetic force by means of which the belt fabric can be held in a positionally fixed relationship on the linear drain. For this purpose, the linear drain is preferably designed to be at least partially metallic, in particular on the upper side of the linear drain to which the belt fabric can or should be attached.

[0010] The term "a number" is used herein in the sense of "one or more."

[0011] The linear drain preferably extends over a first length along the longitudinal direction of the linear drain, the first length being greater, preferably a plurality of times, than the width of the linear drain perpendicular to the longitudinal direction. Thus, for surface drainage, for example, surface water can be absorbed and drained substantially linearly along the length of the linear drain.

[0012] Since the tape fabric is designed to reversibly cover the opening of the linear drain, the tape fabric can be removed and reused, for example, after the linear drain has been inserted into the ground. By covering the opening, it is possible, for example, to prevent material (e.g. filler material) from pouring into the linear drain during installation of the linear drain into the ground. Preferably, the protective plate remains on the linear drain during construction to prevent contamination of the device, groundwater and drainage system. Since the length of the tape fabric is greater than the length of the linear drain, the tape fabric can be flexibly used for linear drains of different lengths.

[0013] Preferably, the opening of the one or more linear drains extends perpendicularly to the longitudinal direction over a maximum width, and the belt fabric has a width perpendicularly to the second length which corresponds to at least the maximum width of the one or more openings of the linear drain, thereby making it possible, for example, to completely cover the opening of the linear drain.

[0014] Preferably provide the belt fabric that is rolled up into a roll.Thereby, the belt fabric can be used in a simple manner, for example by unrolling the roll, and / or stored in a space-saving manner.

[0015] Preferably, the belt fabric also has a length dimension, in particular a centimeter dimension, extending over a second length. Thus, for example, it is possible to simplify the cutting or severing of the linear drain device to a desired overall length.

[0016] Preferably, the magnetic layer is designed at least partially as a permanent magnet and / or an electromagnet. Thus, for example, a magnetic force for holding or fastening the belt fabric to the linear drain device can be provided in a simple manner.

[0017] The magnetic layer is preferably designed as a magnetic film, which further preferably has a thickness of 0.5 mm to 1.5 mm, particularly preferably about 0.75 mm. Alternatively or additionally, the magnetic holding force that can be exerted by the belt fabric is preferably in the range of 20 cN / cm 2 and 80cN / cm 2 between 40 cN / cm 2 and 70cN / cm 2 between 50 cN / cm 2 and 57cN / cm 2 Alternatively or additionally, the magnetic layer with fabric preferably has a residual magnetic flux density B of 150 mT to 200 mT, in particular 170 mT to 180 mT. R Alternatively or additionally, the coercive field strength of the magnetic layer is preferably in the range of 100 kA / m to 110 kA / m and in particular approximately 103 kA / m. The information on the holding force refers to an air gap of d = 0 mm and is defined as the pull-out force perpendicular to the bearing surface (in cN / cm 2as units).

[0018] Thus, for example, a belt fabric can be provided which, on the one hand, exerts a sufficiently large magnetic force for maintaining the belt fabric in a fixed position relative to the linear drain device. On the other hand, for example, a magnetic force can be provided which allows the belt fabric to be separated from the linear drain device, in particular manually.

[0019] The belt fabric preferably further comprises at least one protective film, which is preferably a plastic film. Further preferably, when the belt fabric is attached to the linear drain device, the protective film is arranged on the side of the belt fabric facing away from the linear drain device. The protective film can, for example, be a self-adhesive film. Thereby, the protective film can be connected to the magnetic layer in a simple manner. The protective film can, for example, protect the magnetic layer from damage, which can improve the reusability of the magnetic layer or the belt fabric.

[0020] The belt fabric is preferably reusable. In other words, the belt fabric is preferably designed as a reusable article. Alternatively, the belt fabric can be designed as a disposable article for this purpose.

[0021] The linear drainage system according to the invention comprises at least one linear drainage device, in particular a drainage trough, which extends in the longitudinal direction over a first length and has one or more openings for receiving surface water, and has a belt fabric as described above. Preferably, the one or more openings of the linear drainage device are designed as one or more slots extending transversely to the longitudinal direction on the upper side of the linear drainage device, preferably as slots of a guard plate, in particular slots of a grate and / or a grid. Thus, for example, a linear drainage device in the form of a box trough with a grate guard plate is provided. Alternatively or additionally, the one or more openings of the linear drainage device are preferably designed as slots extending in the longitudinal direction on the upper side of the linear drainage device. Thus, for example, a linear drainage device in the form of a slotted trough can be provided. Preferably, the upper side of the linear drainage device at least partially consists of and / or has a metal material. Thus, a drainage system is provided, which is, for example, well suited to the use of the belt fabric as described above, and in particular enables a simplified installation of the linear drainage device.

[0022] The use according to the invention of the above-described belt fabric and / or the above-described linear drainage system is for installing a linear drainage device, wherein the linear drainage device extends over a first length in the longitudinal direction and has one or more openings for receiving surface water, and comprises at least the following steps:

[0023] a) introducing at least one linear drainage device into the ground, in particular by concreting and / or embedding in an embedding material,

[0024] b) attaching a fabric strip to the upper side of the linear drain so that the fabric strip covers at least the one or more openings, and

[0025] c) Use fill material to fill areas adjacent to linear drains.

[0026] Preferably, in step a), one or more linear drains adjacent to each other in the longitudinal direction are introduced into the ground and further preferably shortened to a predetermined length in the longitudinal direction. Alternatively or additionally, the use comprises the further step of separating the belt fabric from the linear drain, in particular by overcoming the magnetic force generated by the belt fabric.

DETAILED DESCRIPTION

[0031] References below Figure 1 and Figure 2 Describes linear drainage devices such as gutters (see Figure 3a to Figure 3c ) with a fabric. Figure 1 A schematic diagram of a belt fabric 1 is shown, the belt fabric being rolled up along the length of the belt fabric to form a roll 2, and Figure 2 A schematic cross-section through the belt fabric 1 is shown, wherein the cross-sectional plane extends perpendicularly to the longitudinal direction of the belt fabric 1 .

[0032] The belt fabric 1 is designed as a strip with a constant width B, which extends in the longitudinal direction L (see Figure 3c ) extends in a length that is equal to the length of the linear drain (see Figure 3a to Figure 3c ) is at least as long or longer. Figure 1 In the embodiment, the belt fabric 1 is rolled up into a roll 2 in the longitudinal direction of the belt fabric. The belt fabric 1 is designed to reversibly cover the opening 13 of the linear drainage device (see Figure 3a to Figure 3cThe width B of the belt fabric 1 corresponds to at least the maximum width of the openings 13 of the linear drain device (see Figure 3a , Figure 3c ).

[0033] like Figure 2 As shown, the belt fabric 1 comprises a magnetic layer 3 and a protective layer in the form of a protective film 4. When the belt fabric 1 is attached to a linear drainage device (see Figure 3a to Figure 3c ), the magnetic layer 3 is arranged on the lower side of the belt fabric 1 and the protective film 4 is arranged on the upper side. On the upper side of the belt fabric 1, that is, on the side facing away from the linear drainage device, a length dimension 5 extending in the longitudinal direction in the form of centimeters is arranged.

[0034] The magnetic layer 3 is designed at least partially as a permanent magnet and / or an electromagnet. In the present embodiment, the magnetic layer 3 is designed as a magnetic film. For example, the magnetic film can have a thickness of 0.5 mm to 1.5 mm. For example, the magnetic film has a thickness of about 0.75 mm, wherein the belt fabric 1 consisting of the magnetic film 2 and the protective film 4 has a thickness of, for example, up to 1.1 mm.

[0035] When the material thickness is 0.75 mm, the magnetic film 3 as a semi-anisotropic magnetic film has a holding force of, for example, 50 cN / cm 2 , and the magnetic film 3 as an anisotropic magnetic film has a holding force of, for example, 57 cN / cm 2 The information on the holding force refers to an air gap of d = 0 mm and is defined as the pull-out force perpendicular to the bearing surface in cN / cm 2 as units).

[0036] The magnetic film 3 has a residual magnetic flux density B R The coercive strength BHc is 179mT, 103kA / m, and 5.49kJ / m 3 or 0.96MGOe maximum energy product BH, 3.6g / m 3 The density and Shore hardness D are 55. For example, the maximum temperature range of use is -15°C to +80°C, temporarily up to 180°C / 220°C. The pole pitch is, for example, 2.1 mm and the magnetic film 3 is multipolar on one side and both sides and is coated with a protective varnish on the magnetic side.

[0037] In the present embodiment, the magnetic film 3 consists of approximately 89% barium ferrite or strontium ferrite, approximately 9.5% plastic elastomer (no PVC (polyvinyl chloride) here) and furthermore 1.5% binder and plasticizer.

[0038] In the present embodiment, the protective film 4 is composed of a PVC weldable self-adhesive film. The length dimension 5 can be provided on or in the protective film 4, for example, in the form of UV printing.

[0039] The magnetic film 3 and the protective film 4 can be implemented as a single layer or multiple layers. A plurality of magnetic films 3 and protective films 4 can also be arranged one after another or alternately. The magnetic film 3 and / or the protective film 4 can be designed to be chemically resistant and / or heat resistant.

[0040] Reference below Figures 1 to 3c The use of the above-described tape fabric 1 for installing a linear drain device is described. Figure 3a A linear drain in the form of a drain channel 10 is shown for use with the belt fabric 1. The linear drain can also include Figure 3a A plurality of drainage grooves 10 are shown in FIG.

[0041] Figure 3a The drain trough 10 shown extends in a length along the longitudinal direction L, which is less than the length of the belt fabric 1. The drain trough comprises a box-shaped trough 11 having a substantially rectangular outer cross-section and a U-shaped recess for absorbing surface water, which is open toward the upper side 10a of the drain trough 10. The drain trough 10 also comprises a guard plate 12, for example, in the form of a grate or a grid, which has a plurality of slits 13 extending transversely to the longitudinal direction L. The slits 13 form openings on the upper side 10a of the drain trough 10, through which surface water can flow into the recesses of the box-shaped trough 11. The slits 13 have a maximum width (not shown in the figure) perpendicular to the longitudinal direction L, which is less than the width B of the belt fabric 1 (see Figure 2 ). Therefore, the gap 13 of the drainage groove 13 can be completely covered by the belt fabric 1.

[0042] One or more drain ports can be provided on the lower side of the drain trough 10 for connection to a drainage system or an infiltration system to carry away surface water (not shown).

[0043] The guard plate 12 is made of a metal material or at least partially comprises a metal material. Alternatively or additionally, the drain groove 10 can at least partially comprise a metal material on the upper side 10a of the drain groove. As a result, the belt fabric 1 can pass through the magnetic film 3 (see Figure 1 , Figure 2 ) is magnetically adhered to the guard plate 12 (see Figure 3c The guard plate 12 can, for example, be placed flat on and / or fastened to a stepped section 14 designed on the upper side 10a of the drain channel 10 (see Figure 3b ) so that the guard plate 12 is essentially flush with the upper side 10a.

[0044] Figure 3b The first step in installing a linear drain is shown. Here, Figure 3a One, preferably more, drainage channels 10 shown in FIG. are introduced into the ground. The upper side 10a of the drainage channel 10 is arranged at a predetermined height. Figure 3bOnly one drain trough 10 is shown in the figure, however, preferably a plurality of drain troughs 10 are introduced into the ground adjacent to one another in the longitudinal direction L. The drain trough 10 is embedded or concreted, for example with a lower section of the drain trough in an embedding material 15, for example concrete or sand.

[0045] exist Figure 3b FIG. 1 shows a single gutter 10 embedded in an embedding material 15, wherein the gutter 10 is not provided with a guard plate 12 (see FIG. Figure 3a However, the gutter 10 can also be inserted into the ground with the guard plate 12 placed (not shown in the figure).

[0046] Then, the guard plate 12 (see Figure 3a ) is attached to the box-shaped groove 11 and the belt fabric 1 is attached to the guard plate 12. The belt fabric 1 is attached to the guard plate 12 so that the longitudinal direction L of the belt fabric 1 coincides with the longitudinal direction L of the drain groove 10 and the magnetic film 3 is disposed on the side of the belt fabric 1 facing the guard plate 12. Figure 2 The magnetic force exerted by the magnetic layer 3 of the drain groove 10 holds the fabric in a fixed position on the guard plate 12. The fabric 1 completely covers the opening formed by the gap 13 of the guard plate 12 on the upper side 10a of the drain groove 10 (such as Figure 3c ). Figure 3c In the view of FIG. 1 , the protective plate 12 is covered by the belt fabric 1 .

[0047] Subsequently, the area adjacent to the linear drainage device, i.e., the drainage trough 10, is filled with the filling material 16. The filling material 16 is preferably filled to a predetermined height so that the filling material forms a ground surface (e.g., Figure 3c ). The filling material 16 can include, for example, concrete, stone, gravel and / or paving stones. Therefore, during the introduction of the filling material 16, the belt fabric 1 is arranged on the protective plate 12 and covers the opening of the protective plate, which prevents the filling material 16 from pouring into the recess of the box-shaped trough 11. The protective film 4 of the belt fabric 1 (see Figure 2 ) can, for example, prevent damage to the cover plate 12 and / or the belt fabric 1 during filling with the filling material 16 (see Figure 2 ) of the magnetic film 3. Figure 3c In the drawing, two drain grooves 10 of a linear drain device adjacent to each other in the longitudinal direction L are shown purely as an example.

[0048] Preferably, the drain groove 10 provided at the end of the linear drain device in the longitudinal direction L is shortened, for example cut off, to obtain the desired total length of the linear drain device. The length of the belt fabric 1 is preferably longer than the desired total length of the linear drain device. The length dimension 5 of the upper side of the belt fabric 1 (see Figure 1) can simplify the shortening of the overall length of the linear drainage device.

[0049] After the linear drainage device has been introduced into the ground and filled with the filling material 16, the belt fabric 1 can be separated from the cover plate 12 again by overcoming the magnetic force, for example by manual removal. The belt fabric 1 can then be reused.

[0050] The belt fabric 1 and the one or more drainage channels 10 can be provided in the form of a linear drainage system.

[0051] Instead of the one or more drainage grooves 10 described above, one or more other suitable elements for linear drainage may be provided as the linear drainage device.

[0052] For example, the linear drain can be provided in the form of a slit groove, wherein one or more openings of the linear drain are designed as one or more slits extending in the longitudinal direction on the upper side of the linear drain.

[0053] Instead of a reusable belt fabric, the belt fabric can also be provided as a disposable item.

[0054] The elements and components of the belt fabrics and linear drainage devices described herein are also not limited to the shapes and sizes described above and shown in the drawings.
