Description

The invention relates to a profiled plastic web for use as a drainage and / or sealing web. Furthermore, the present invention relates to a system with a plurality of profiled webs, wherein the webs are overlapped at the longitudinal edges.

Profiled canvases serve in the field of construction to protect insulating layers of building parts in the ground from moisture and / or heat from mechanical damage. In addition, profiled webs can also have a drainage function, which allows leakage of water to drain in the intermediate spaces between the pimples, so that moisture accumulation on parts of the building is prevented. However, only with the help of known profiled webs, as a rule, it is not possible or possible only at high cost to create a liquid-impermeable layer, so another layer must be provided for this purpose.

The objective of the invention is to provide a profiled web that allows easy connection with other profiled web. In addition, the object of the present invention is to provide a system with a plurality of profiled webs, the webs being connected to each other impervious to liquids.

This problem is solved in a profiled plastic sheet of the above kind by the fact that in the area to be laid with overlapping longitudinal edges of the sheet, sealing elements, in particular sealing strips, are provided that allow the sheets to be connected to each other impervious to liquid. In accordance with this, in the system according to the invention, several profiled webs are provided, which are connected at each longitudinal edge to each other and are impervious to liquid by means of sealing elements or correspondingly sealing strips.

In one preferred embodiment, the web is firmly connected, in particular, on both longitudinal edges on both sides by means of a corresponding sealing element, in particular a sealing strip, which is located along the longitudinal edge or, respectively, the longitudinal edges once on the upper side and once on bottom side. Sealing strips may taper during manufacture.

If the edge zones of the web are made on at least one, preferably on both longitudinal sides, smooth, i.e. without profiles, there is an ideal surface for applying a sealing element or, accordingly, a sealing strip. The edge zones made in this way can usually have a width of from 2 cm to 100 cm, preferably from 5 cm to 50 cm, particularly preferably from 10 cm to 30 cm.

When laying with overlapping sealing elements are superimposed on each other and they can, for example, be directly welded to each other using a conventional welding device using hot air. In addition to this, according to the invention, it is also possible to carry out the connection using the solvent diffusion welding method or by gluing.

Thus, the drainage and sealing web can be connected in the overlap zone impervious to liquid, in particular impervious to water.

As an alternative solution, in another embodiment, only one longitudinal edge is connected to the sealing element, the overlap zone can be welded as in the above case.

Sealing strips can usually have a width of 1 cm to 40 cm, preferably 5-15 cm, particularly preferably 8-10 cm.

Sealing elements consist of a well-welded material with high elongation and high tensile strength. The material of the sealing strips should not be identical to the material of the profiled web.

The material of the sealing elements can be selected, for example, from the group consisting of polyolefins, for example low density polyethylene, ethylene vinyl acetate, polypropylene, polyvinyl chloride, polystyrene, polystyrene modifications, acrylonitrile-butadiene-styrene, styrene-acrylonitrile, styrene-acrylonitrile-fkryloester, ethylene diene rubber or styrene-ethylene-butylene-styrene or their compounds.

The profiled web, according to the invention, serves as a drainage and sealing web for performing drainage and for sealing in the layer. Thus, the canvas, along with drainage, also simultaneously performs the compaction function. To date, this required, as a rule, several products.

Moreover, the seal in the sense of the invention should be understood as a seal with respect to leaking water. The seal density can be checked, for example, in accordance with EN 13859-1 and EN 13859-2. Moreover, the passage of water at a pressure of 200 mm of water is usually not more than 100 ml per linear meter of overlap per hour, preferably less than 1 ml per linear meter of overlap per hour, particularly preferably less than 0.1 ml per linear meter of overlap per hour .

Welding of the web usually has a shear strength of more than 200 N per 5 cm, preferably more than 300 N per 5 cm, when tested in accordance with EN 12317-2.

Welding of the web typically has a peeling resistance of more than 200 N per 5 cm, preferably more than 300 N per 5 cm, when tested for T-peeling in accordance with DIN EN ISO 11339.

In another embodiment, the sealing strips consist of a material suitable for solvent diffusion welding and are joined to each other impervious to water by means of solvent diffusion welding. In this case, the solvent diffusion welding means dissolves the sealing strip in some zones and thereby allows welding between the sealing stripes lying on each other. Solvents can be selected, for example, from the group consisting of alkanes, alkenes, aromas, organochlorines, alcohols, esters, esters, ketones, aminoketones or heterocyclic compounds.

In another embodiment, the sealing strips are made in the form of adhesive strips that are glued and thereby connected to each other impervious to water. In this case, the web can be coated on both sides with a corresponding single adhesive strip, which is preferably located along the longitudinal edges once on the upper side and once on the lower side. Adhesive strips can be covered with a protective film. When laying, the protective film after the overlap is completed is removed on both sides, and the overlap is glued tightly to the adhesive. Possible adhesives include PSA adhesives.

As an alternative solution, only one longitudinal edge is covered with an adhesive strip, while the overlap is glued together as in the above case.

In another embodiment, the web is made with at least one additional connecting element, preferably with several connecting elements, for example, connecting profiles, which can be arranged at regular intervals, for the formation, in particular, connection with geometrical closure of the profiled fabric with at least one other canvas. The profiles of adjacent webs can be located in the area adjacent to the sealing strip and can be made to dock with each other, for example, due to the fact that small profiles and large profiles as the corresponding connecting element are arranged accordingly.

The profiled web preferably has at least one corresponding connecting element on its longitudinal edges, in particular, the connecting element designed for one longitudinal edge is made in the form of a connecting profile, and the connecting element designed for the other longitudinal edge is made in the form of a corresponding connecting profile or in the form of a corresponding insertion hole.

This embodiment is preferable for accurate positioning and for setting the position or, accordingly, preliminary fixing of the overlap before welding.

Due to the optional execution of the undercut groove, it is possible to carry out a fixing connection with increased reliability of the connecting element with the interacting connecting element. The undercut groove is usually 0.2–2 mm.

The connecting profiles may have a distance from each other, usually 1-100 cm, preferably 5-50 cm, particularly preferably 10-30 cm.

In addition to this, there is the possibility, after fitting profiles onto each other, by means of mechanical deformation of the profiles, for example, by means of hammer blows, to turn a connection with a geometric closure into an additional connection with a power closure. A prerequisite for this is the use of sufficiently shockproof under the processing conditions of the material of the connecting profiles. In this case, usually the impact strength of the IZOD notched material sample is more than 4 kJ per square meter, preferably more than 6 kJ per square meter when tested at 20 ° C in accordance with DIN EN ISO 180.

It is clear that the connecting element can in principle be made in various ways. In particular, the connecting profiles can have almost any shape.

In addition, it is also possible execution of a groove that extends along the longitudinal side of the web. Due to the corresponding differently large profile of this groove, on the opposite longitudinal sides of the web, two adjacent, in particular identical, webs can be connected with a geometric closure due to the entry of a groove with a smaller profile into a groove with a large profile. This ensures that the webs are fixed relative to each other in a direction perpendicular to the longitudinal edge of the web, while it remains possible to shift the webs in a direction parallel to the longitudinal edge until they are fixedly connected to each other and, in particular, impervious to liquid behind expense of connecting the connecting elements.

Also in the case of such a connecting groove, it remains possible to form an undercut groove for making a locking connection. In this case, the undercut groove in the profile is usually 0.02–2 mm.

In another embodiment, the web is made with fixing profiles / insert profiles and corresponding holes, which can be arranged at regular intervals, to form a connection with a geometric closure, while, respectively, the profile and insert hole of two adjacent paintings coincide, and it is possible to insert a profile into the insertion hole.

The diameter of the hole is selected according to the profile. Usually it is 5-50 mm, preferably 10-20 mm.

By performing an undercut groove, a locking connection is formed on the profile. The undercut groove is usually 0.2–2 mm.

The fixing profiles / insert profiles and corresponding holes usually have a distance of 1 cm to 100 cm from each other, preferably 5-50 cm, particularly preferably 10-30 cm. This embodiment is preferred for positioning and pre-fixing before welding and provides greater freedom when choosing design and manufacturing.

In addition, an insertion hole in the form of an elongated hole can be made so that a certain clearance remains for movement.

As an alternative solution or in addition to the undercut groove, it is also possible, in the embodiment with profiles and insertion holes, to perform a geometric closure due to mechanical deformation (for example, by means of hammer blows). A prerequisite for this is the use of sufficiently shockproof under the processing conditions of the material of the connecting profiles. In this case, usually the impact strength of the IZOD notched material sample is more than 4 kJ per square meter, preferably more than 6 kJ per square meter when tested at 20 ° C in accordance with DIN EN ISO 180.

In another embodiment, the sealing element may be a sealing strip that forms a sealing lip that, due to the pressing pressure, is hermetically connected. For example, a rubber sealing tape is hermetically pressed due to a Velcro type joint.

A profiled web usually consists of a polyolefin plastic, preferably HDPE or PP, as well as polystyrene, PVC, polycarbonate, ABS, SAN, PET or PBT. Moreover, profiles and strips may consist of various materials.

The width of the profiled web according to the invention is preferably 1-4 m, particularly preferably 2-3 m.

The length of the fabric, preferably when folded, is usually 10–40 m, preferably 15–25 m.

The surface weight of such a web is usually 300-1500 g per square meter, preferably 500-1000 g per square meter.

The canvas for drainage is equipped with profiles. The profiles can be made, for example, in the form of cylinders, truncated cones, conical, star-shaped or polygonal. They can be made in one direction or in two directions in the form of double profiles.

The canvas usually has a drainage capacity of 1.0 L per meter per second to 4.0 L per meter per second when tested in accordance with EN ISO 12958 with a gradient of 1 and a temporary load of 20 kPa.

The height of the profiles is usually 4–25 mm, preferably 8–12 mm.

The diameter of the profiles is usually 5-50 mm, preferably 10-30 mm, particularly preferably 15-25 mm.

The web typically has a compressive strength of 100 kN per square meter to 1000 kN per square meter, preferably 200 kN per square meter and 800 kN per square meter, when tested in accordance with DIN EN ISO 25619-2 in a parallel plate test.

Resistance to alkalis and acids is preferably provided, in particular in accordance with EN 13984, EN 14030, and also EN 14909, Appendix C.

In another embodiment, the web may be non-combustible and thereby fulfill the requirement of difficult ignition in accordance with EN 13501-1.

A layer, in particular a fabric layer, can serve, for example, as a reactive base for stucco. In this next working step, for example, plaster or syringe concrete can be directly applied to this layer. The layer is located in the laid state of the profiled web, preferably on the front side.

In another preferred embodiment, the web may have a protective layer, in particular a non-woven material, which, when folded, is preferably located on the back side. Such a layer protects the drainage plane of the web formed by the profiles, on the one hand, from contamination. On the other hand, it acts as protection against point mechanical stress or, accordingly, damage due to non-flat soil.

If the fabric has a textile material, preferably non-woven material, then you can use the points or strips of Velcro, in particular their hook part, as an aid to installation. The points and strips of Velcro can be pre-applied to the surface, in particular glued, and hold the temporarily profiled fabric first while compressing according to the principle of bonding like Velcro. In the next working stage, permanent fastening can then be carried out using other fastening means.

The profiled web, in turn, can also have mounting or welding points for simplified application of other layers, such as, for example, supporting fabrics or additional sealing web.

A typical application for these canvases is, for example, use in the construction of tunnels, in particular for sealing tunnel structures from leaking water, sealing green roof surfaces with a flat roof or a steep roof, or for horizontal or vertical drainage and sealing on a building.

Alternatively, plates are also possible. In this case, a circumferential sealing strip and / or circumferential connecting pimples may be provided.

In addition, in particular for a water-tight connection of two abutting webs, a transverse connection may be formed, for example, in the form of an insertable sealing strip. At the same time, such a sealing strip can be superimposed overlapping at the junction and welded directly to the canvases, for example, using a conventional welding device using hot air. Thus, the drainage and sealing web can be transversely connected impervious to water.

In addition, according to the invention, it is also possible that the applied sealing strips consist of a material suitable for solvent diffusion welding and / or have glue, so that the abutting webs can be connected to each other by means of sealing strips by solvent diffusion welding or, respectively, by gluing .

Such a sealing or connecting strip may also be suitable, for example, for sealing with a profiled web in the tunnel connecting the arch with the sole.

The following is an example of an explanation of the invention with reference to the accompanying drawings, which are schematically depicted:

FIG. 1 - profiled canvas, according to the invention, with sealing strips and connecting profiles at the longitudinal edges;

FIG. 7, 8 - laying of two profiled webs shown in FIG. 6 views, while the connecting profiles in the area of overlapping paintings are inserted into each other;

FIG. 9 is a third embodiment of a profiled web according to the invention, wherein connecting profiles are provided on one longitudinal edge of the web, and insertion holes for connecting profiles are provided on the other longitudinal edge;

FIG. 10, 11 - laying shown in FIG. 9 profiled web, while the connecting profiles of the first web in the overlapping zone of the two web are inserted into the insertion holes of the second web;

FIG. 12 is a preferred embodiment of a profiled web according to the invention, with connecting profiles having an undercut groove; and

FIG. 13 is another embodiment of a profiled web according to the invention, wherein a layer is provided for protecting the profiled web from contamination and / or damage.

In FIG. 1 shows a portion of a profiled web 1, according to a preferred embodiment of the invention, made of plastic. The profiled web 1 has on the predominant part of its surface profiles 2, due to which its mechanical protective effect, as well as its drainage function, is ensured. On both sides of the surface occupied by the profiles on the longitudinal edges 3, an edge zone 4 is provided in which the profiled web 1 does not have profiles 2, i.e. free from profiles.

For the liquid tight connection of the two profiled webs 1 of the kind shown here, corresponding sealing elements are provided in the edge zones 4. In this case, the profiled web 1 has a sealing strip 5 located on the upper side, and on the opposite side of the profiled web 1, a connecting strip 6 located on the lower side. The sealing strips 5, 6 in this case consist of a material suitable for welding with hot air. It is also possible to use a material intended for diffusion welding with a solvent or glue in general.

During installation, two profiled webs 1 are laid overlapping so that the upper sealing strip 5 of one profiled web 1 and the sealing strip 6 of the other profiled web 1 located on the lower side overlap in at least some areas, as shown in FIG. 4. After this, the profiled webs 1 are brought into contact with each other by their sealing strips 5, 6, and the sealing strips 5, 6 are connected to each other with a material short circuit, for example, by heating with a conventional hot air welding device, whereby an impermeable for liquid, the connection of both profiled webs 1, as shown in FIG. 5.

The above principle construction is also shown in FIG. 2 an alternative embodiment of the profiled web 1 according to the invention, as well as provided in the schematically shown in FIG. 3–11 profiled canvases shown in section 1. The explained basic principle also applies to the installation of all the embodiments presented here.

As shown in FIG. 1 of a preferred embodiment of the profiled web 1 according to the invention, connecting elements are further provided on the side of the edges that facilitate the relative orientation of the profiled web during installation. Due to this, optimal overlap of both sealing strips 5, 6 during installation can be ensured, so that a particularly reliable liquid tight connection between the profiled webs 1 is obtained.

The connecting elements are made in this case in the form of small connecting profiles 7 and large connecting profiles 8. Moreover, the connecting profiles 7, 8 are provided on the upper side, while the small connecting profiles 7 are located on the upper sealing strip 5, while the large connecting profiles 8 located on the lower sealing strip 6.

The upper sealing strip 5 and the smaller connecting profiles 7, as well as the lower sealing strip 6 and the large connecting profiles 8 are located relative to each other so that when laying large profiles 8 overlap the small profiles 7, and the lower sealing strip 6 overlaps the upper sealing strip 5, as this is shown in FIG. 7. In this case, in particular, the small connecting profiles 7 enter from below into the large connecting profiles 8, as shown in FIG. 8, wherein the profiled webs 1 are fixed relative to each other in the direction transverse to the longitudinal edge 3.

Preferably, the upper sealing strip 5 is located from the small connecting profiles 7, measured from the middle to the middle, at the same distance as the lower sealing strip 6 from the large connecting profiles 8, so that the connecting strips 5, 6 almost completely overlap with a comparable width each other. At the same time, when connecting the sealing strips 5, 6 with a power circuit, a particularly strong and reliable liquid-tight connection of the profiled canvases 1 is obtained, while the installation labor, to achieve this result, is significantly reduced due to the sealing profiles 7, 8.

As shown in FIG. 2, respectively in FIG. 9-11, an alternative embodiment of the profiled web 1, instead of large connecting profiles 8, insert holes 9 are provided.

Shown in FIG. 10 and 11, the laying steps of the profiled webs 1 according to this embodiment correspond in principle to those shown in FIG. 7 and 8 stages with the difference that in this case, the connecting profiles 7 of one profiled web 1 are brought into overlap with the insertion holes 9 of the other profiled web 1. However, in this case too, due to the location of the upper sealing strip 5 at the same distance from the connecting profiles 7 that the lower sealing strip 6 from the insertion holes 9, when measured from the middle to the middle, as shown in FIG. 10, optimum overlap of the sealing strips 5, 6 is achieved when the connecting profiles 7 of one web are inserted into the insertion holes 9 of the other web.

Although not shown in FIG. 6-11, however, it is also possible, according to the invention, and a preferred embodiment of the profiled web 1 according to the invention, in which at least the small connecting profiles 7 have an undercut groove 10, so that, as shown in FIG. 12, a locking connection is obtained between the small connecting profiles 7 and preferably also having an undercut groove 10 with large connecting profiles 8 or, respectively, insert holes 9.

In FIG. 13 shows another embodiment of a profiled web 1, according to the invention, in which an additional layer 11 is provided. In this case, the layer 11 is located on the side of the profiles 2 and thus in the mounted state on the rear side of the profiled web 1. The profiled web 1 is protected by layer 11 from damage and pollution. Since the ingress of dirt or, correspondingly, soil into the intermediate spaces between the profiles 2 is prevented, the drainage function of the profiled web 1 is maintained using the layer 11.

Layer 11 has, in particular, a nonwoven fabric or comparable textile material. In addition to the protective properties indicated above, such a fabric is characterized in that in order to simplify the installation of the profiled web 1, first, auxiliary mounting means are applied to the surface to be coated, for example, Velcro spots or strips having hooks as part of the Velcro joint. When the profiled web 1 is pressed against the surface with the above Velcro-type joint elements, the profiled web 1 is temporarily held by the principle of Velcro bonding, while layer 11 represents the looped part of the Velcro joint. In the next working step, permanent fastening of the profiled web 1 to the surface can be carried out with low costs using suitable fastening means.
