Description

[0001] Ventilation profile for actively ventilating and / or venting a building waterproofing system, building waterproofing system, and methods for actively ventilating and / or venting a building waterproofing system.

[0002]

[0001] The invention relates to a ventilation profile for actively ventilating and / or extracting moisture from a building waterproofing system, wherein the building waterproofing system protects and / or seals a wall of a building, in particular a house, on an outer surface of the wall by means of a moisture-proof or moisture-resistant protective layer against penetrating moisture from surrounding soil, wherein the protective layer is arranged in a protective layer plane spaced from the wall by means of spacers between the wall and surrounding soil and thus a ventilation space is formed between the protective layer and the wall, wherein a connecting strip is arranged on an upper connecting line of the protective layer along a connecting axis and the protective layer is connected to the wall at an upper connecting line by means of the connecting strip, wherein the connecting strip has at least one fluid-carrying ventilation access to the ventilation space.Furthermore, the invention relates to a building waterproofing system with such a ventilation profile and to a multi-step method for actively ventilating and / or de-ventilating a building waterproofing system.

[0002] It is known to protect buildings against moisture, at least in the area of ​​soil. This involves the use of so-called protective layers, which are designed, for example, as dimpled membranes or similar materials. These protective layers are arranged, for example, in the area of ​​basement walls and / or foundations outside the masonry and can include spacers, so that a ventilation space is formed between the protective layer and the corresponding wall.The corresponding protective layers are often connected to the wall in an upper area with a connecting strip, so that, for example, rain penetration is prevented and, in addition, appropriate gaps or openings in the connecting strip allow moisture to escape from the ventilation space.

[0003]

[0003] The object of the invention is to improve the state of the art.

[0004]

[0004] The problem is solved by a ventilation profile for actively ventilating and / or extracting air from a building waterproofing system, wherein the building waterproofing system protects and / or seals a wall of a building, in particular a house, on an outer surface of the wall by means of a moisture-tight or moisture-resistant protective layer against penetrating moisture from surrounding soil, wherein the protective layer is arranged in a protective layer plane spaced from the wall by means of spacers between the wall and surrounding soil and thus a ventilation space is formed between the protective layer and the wall, wherein a connecting strip is arranged on an upper connection line of the protective layer along a connection axis and the protective layer is connected to the wall at an upper connection line by means of the connecting strip, wherein the connecting strip has at least one fluid-carrying ventilation access to the ventilation space.wherein the ventilation profile has a connection geometry, an interior, a first sealing contour and a second sealing contour and a first ventilation connection connected to the interior in a fluid-carrying manner, wherein the ventilation profile can be mounted on the connection strip by means of the connection geometry, wherein in a mounted position the first sealing contour seals with the connection strip and the second sealing contour seals with the protective layer, so that active ventilation and / or venting of the ventilation space is enabled by means of the first ventilation connection through the at least one ventilation access.

[0005]

[0005] The invention thus makes it possible to actively ventilate the ventilation space behind the protective layer in the area of ​​the wall or masonry and thereby, for example, to dry it out in the event of heavy rain, flooding, or other events that have moistened or saturated a corresponding wall. Air can then be actively extracted from the interior of the ventilation profile, so that the moisture present in the ventilation space is removed convectively.

[0006]

[0006] The following terms shall be explained in this context:

[0007] A "ventilation profile" refers to a profile made, for example, of a metal material or of another material, with in particular the same or substantially the same cross-section along a corresponding longitudinal extent, wherein the profile is suitable and designed to ventilate and / or vent a building seal.

[0007]

[0008] A "building waterproofing system" refers to a system designed and installed to seal a building, particularly against moisture, such as water or water vapor. A "building" in this context is primarily a structure constructed from mineral materials, such as bricks or clinker bricks; for example, such a building could be a house or other residential or commercial building. A building can also be constructed from renewable materials such as wood or wood-based materials. The technical objective of building waterproofing is to keep moisture away from the building, and especially from moisture-sensitive areas, or at least to reduce the penetration or accumulation of moisture.

[0008]

[0009] A "wall" is, in particular, a vertical component of a building, for example, when it serves as a basement wall or exterior wall. The wall extends into the ground at the surface, with "ground" here referring to the soil surrounding the building or structure.

[0010] In this context, a "protective layer" refers in particular to a layer, for example a film or foil-like material, which is applied to protect the building, especially the wall, against penetrating moisture. Such a protective layer usually runs essentially parallel to the wall.

[0009]

[0011] “Penetrating moisture” describes in particular moisture that migrates from the surrounding soil towards the wall and then, for example, enters the wall; penetrating moisture can also refer to rising moisture from the soil, for example from an area below the building, towards the wall or in the wall.

[0010]

[0012] The wall has an "outer surface", i.e. a finishing surface or contact surface directed towards the ground.

[0011]

[0013] The protective layer is designed to be "moisture-resistant," meaning that it reduces the passage of moisture, particularly towards the outer surface of the wall. Alternatively, the protective layer can be designed to be "moisture-proof," meaning that it is technically possible to achieve, and in particular completely impervious to, moisture.

[0012]

[0014] The protective layer is essentially aligned parallel to the wall, thus forming a "protective layer plane." This protective layer plane specifically refers to the surface plane in which the protective layer is arranged. It should be noted that such a protective layer plane does not necessarily have to be a mathematically exact plane, but can, for example, follow locally corresponding waveforms or even kinks in the protective layer. Essentially, the protective layer plane describes a macroscopic plane in which the protective layer runs along or is arranged on the wall.

[0013]

[0015] An "upper connection line" refers to a line defined by an edge or, for example, a cut edge of the protective layer, which, in a mounted position of the protective layer on the wall, is located at the top, i.e., against the direction of gravity. It should be noted that here, too, the "line" may deviate from a mathematically exact straight line and may, for example, be a line altered by folds, waves, or other geometric deviations of the protective layer, which, for instance, runs along a macroscopic line or straight line but is meandering microscopically. The fundamental concept of the connection line in this context is that an upper edge of the protective layer is geometrically defined.

[0014]

[0016] A "spacer" is, in particular, a protruding structure of the protective layer in the direction of the wall, so that a "space", i.e., a free space, is formed between the protective layer and the wall.

[0015]

[0017] This means that the protective layer is positioned at a distance from the outer surface of the wall; the space in between, i.e., the distance between the protective layer and the wall, is referred to as the "ventilation space", whereby this ventilation space allows, in particular, for example, a free space for air into which moisture from the wall or on the wall can evaporate, so that the air in the ventilation space can then absorb the moisture and, for example, carry it away.

[0016]

[0018] It should be noted that a “fluid-carrying ventilation access” refers in particular to an access permeable to air or flowing air, which is designed, for example, as a recess in the connection strip in such a way that the ventilation space is accessible and thus ventilated or extracted.

[0017]

[0019] A “connection geometry” refers in particular to a geometry, i.e. a geometric design, of the ventilation profile such that a connection to the connection strip is possible in such a way that the ventilation profile is connected to the connection strip, positioned on the connection strip or fixed opposite the connection strip.

[0018]

[0020] An "interior space" refers to a space within the ventilation profile that is, for example, partially enclosed or, in the installed position, completely enclosed, such that the ventilation profile encloses or partially encloses a volume forming the interior space. In particular, the interior space is permeable to air or another fluid. A "sealing contour" serves to create a fluid-tight or substantially fluid-tight seal between the ventilation profile and corresponding components of the building's waterproofing system. This sealing contour is designed, for example, as a line or curve, to ensure a fluid-tight seal against the building's waterproofing system on the corresponding components.It should be noted that complete tightness does not need to be achieved here, but rather a level of tightness sufficient for ventilating the ventilation room is achieved, for example, if the sealing contour essentially follows the contour of the building.

[0019]

[0021] A "ventilation connection" refers to a connection, for example designed as a pipe section or as a flange, which is arranged on the ventilation profile in such a way and is fluid-carrying and continuous with respect to the interior, so that, for example, an external turbomachine can be connected to carry out the ventilation.

[0020]

[0022] “Active ventilation” refers in particular to the mechanical or technical movement of fluid, for example ambient air or dried ambient air, through the ventilation connection and thus also into or out of the ventilation room, so that, for example, active drying of the ventilation room or the wall behind it is made possible.

[0021]

[0023] According to one embodiment of the invention, the first sealing contour and / or the second sealing contour are aligned parallel or substantially parallel to a longitudinal axis of the profile and, in the mounted position, particularly parallel or substantially parallel to the upper connection line of the protective layer. This allows, for example, the use of a ventilation profile with a uniform and consistent profile along the longitudinal axis, by utilizing, for instance, a straight alignment of the building waterproofing to achieve the necessary tightness through the substantially straight sealing contours.

[0022]

[0024] The "profile longitudinal axis" refers in particular to the reference axis of the ventilation profile, i.e. an axis on which corresponding cross-sections are arranged, the multiplicity of which then forms the ventilation profile.

[0023]

[0025] According to a further embodiment of the invention, the interior space is formed by means of an interior area of ​​an open profile cross-section of the ventilation profile, wherein the first sealing contour and / or the second sealing contour is or are formed by means of an edge or by means of the edges of the ventilation profile formed thereby which is open on at least one side.

[0024]

[0026] For example, a C-shaped, semicircular, or otherwise open profile can be used as a ventilation profile, so that corresponding edges, which are automatically provided by the geometry of the profile, are used as sealing contours. The interior space is then formed by means of an inner area of ​​the open profile cross-section, i.e., by means of a concave area of ​​the respective profile cross-section and thus a concave longitudinally extended area of ​​the ventilation profile.

[0025]

[0027] To enable, for example, active ventilation and also venting or also ventilation of the ventilation profile for the removal or discharge of moisture, a second ventilation connection, a third ventilation connection and / or a further ventilation connection is fluid-carrying connected to the interior, whereby simultaneous or alternating active ventilation and / or venting of the ventilation space through the at least one ventilation access is enabled by means of the first ventilation connection and the second ventilation connection and / or the third ventilation connection and / or the further ventilation connection.

[0026]

[0028] It should be noted that the ventilation profile can also be designed in multiple parts, so that, for example, a specific section of the ventilation profile, or a single ventilation profile combined with other ventilation profiles, has corresponding ventilation connections, thus enabling, for example, air to be blown through the ventilation profile and the ventilation space. Individual ventilation profiles or sections thereof can be provided with appropriate seals or gaskets along the longitudinal axis of the profile, enabling specific fluid flow, i.e., airflow, within the ventilation profile and the ventilation space.

[0029] In a further embodiment of the invention, the connection geometry has a fastening means, wherein the fastening means is designed corresponding to a fastening recess on the connection profile and by fixing the fastening means to the fastening recess in the mounted position a force-guiding fastening of the ventilation profile to the connection profile is achieved.

[0027]

[0030] This allows, for example, the ventilation profile to be fixed or attached to the connection profile, enabling not only negative pressure ventilation and / or exhaust, but also positive pressure ventilation or exhaust with a corresponding positive pressure difference compared to the ambient atmosphere. This essentially prevents the ventilation profile from being blown off or lifted from the connection profile by positive pressure.

[0028]

[0031] A "fastening element" with a corresponding "fastening connection" can be designed as either a tool-removable or tool-free fastener. For example, a screw connection, a click connection, a snap-fit ​​connection, or a barbed connection can be used. The connection can also be reversible, allowing the fastening profile to be removed, for example, after a wall has dried. It should be noted that the ventilation profile can also be designed as a replacement profile for an additional strip on the connection profile, such as a rain strip. This allows for both standard sealing of the building's waterproofing against rain and ventilation with or using the ventilation profile in the event of excessive water ingress.In particular, the connection geometry is formed from a free leg or legs of the ventilation profile, with the fastening means being arranged on the respective free leg.

[0029]

[0032] In another embodiment, the ventilation profile is an extruded profile or has such an extruded profile. Likewise, the ventilation profile can be formed by means of an extruded profile.

[0030]

[0033] An "extruded profile" is, in particular, a profile made of, for example, aluminum or steel, which is pressed through an extrusion die in a flowable or partially softened state and thus has a profile that is uniform along its longitudinal axis.

[0031]

[0034] In another aspect, the problem is solved by a building waterproofing system, wherein the building waterproofing system protects and / or seals a wall of a building, in particular a house, against penetrating moisture from surrounding soil on an outer surface of the wall by means of a moisture-proof or moisture-resistant protective layer, wherein the protective layer is arranged in a protective layer plane, spaced from the wall by means of spacers, between the wall and surrounding soil, thus forming a ventilation space between the protective layer and the wall, wherein a connecting strip is arranged on an upper connection line of the protective layer along a connection axis, and the protective layer is connected to the wall at an upper connection line by means of the connecting strip, wherein the connecting strip has at least one fluid-carrying ventilation access to the ventilation space.wherein a ventilation profile arranged in the mounted position according to one of the previously described embodiments is attached or arranged on the building waterproofing.

[0032]

[0035] According to one embodiment, the building waterproofing system has a turbomachine connected to the first ventilation connection, the second ventilation connection, the third ventilation connection and / or the further ventilation connection, particularly for the purpose of drying or ventilation.

[0033]

[0036] In this context, a "flow machine" refers in particular to a blower or a device acting, for example, as a compressor, or a corresponding arrangement, whereby, as an alternative to a blower arrangement driven, for example, by a motor, stored compressed air from a compressed air tank can also be used to supply and actively ventilate the ventilation connection. The core idea of ​​the invention in this context is to transport corresponding quantities of gas, i.e., air, through the structure and through the building's waterproofing, whereby the specific design of the technical means for this purpose can be expediently selected.

[0034]

[0037] According to another aspect, the task is solved by a method for actively ventilating and / or de-ventilating a building waterproofing system with the following steps:

[0035] - Mounting the ventilation profile on the connection strip, so that the ventilation profile is arranged and / or mounted on the connection strip in the mounted position ,

[0036] - Connecting a turbomachine to the first

[0037] Ventilation connection, the second

[0038] ventilation connection, the third

[0039] ventilation port and / or the further ventilation port, so that the turbomachine is fluid-carrying connected to the respective ventilation port,

[0040] - Activate the turbomachine so that through the first ventilation port, the second ventilation port, the third

[0041] ventilation connection and / or the further ventilation connection an active ventilation and / or venting of the ventilation space through which at least one ventilation access is reached, so that the building seal is actively ventilated.

[0062]

[0039] A basement waterproofing system 101 on a house 103 is intended to prevent moisture from the ground 105 from penetrating a basement wall 107. A floor slab 109 seals off the house 103 at the bottom, adjoining the basement wall 107.

[0063]

[0040] The basement waterproofing 101 is created by means of a protective film 121. The protective film 121 has nubs 123 which are arranged in the direction of the basement wall 107. These nubs 123 serve as spacers. This creates a ventilation space 129 between the protective film 121 and the basement wall 107, or between an outer surface 181 of the basement wall 107 and a protective layer 183 of the protective film 121.

[0064]

[0041] The protective film 121 is covered at the top by a rain strip 131, which extends over the top and is clicked into a connecting strip 133 (not shown in detail). The connecting strip 133 also serves to mechanically connect the protective film 121 to the wall. An overhang 122 of the protective film 121 projects upwards below the rain strip 131, thus preventing the ingress of driving rain into the ventilation space 129.

[0065]

[0042] An air slot 135 allows rising air in the ventilation chamber 129 to be discharged, whereby, for example, an active ventilation system (not shown) can be introduced in a lower termination 141 to enhance the airflow in the ventilation chamber 129. This allows the basement wall 107 to be freed from moisture by the ventilation chamber 129. It should be noted that the rain strip 131 only projects beyond the connecting strip 133 to the extent necessary, particularly downwards, to allow air to escape from the ventilation chamber 129, for example, by free convection. To this end, the rain strip 131 projects only minimally below the protective foil 121, for example, a few millimeters, or even ends above the protective foil, with a lateral gap at the lower end of the rain strip 131 preventing the ingress of rain or other falling particles.

[0066] Moisture is prevented.

[0067]

[0043] It should be mentioned that, for the installation of the basement waterproofing 101, the soil 105 can be excavated down to a straight edge 165, thus facilitating the flat installation of the protective membrane 121 and the arrangement of connecting strip 133 and rain strip 131. After installation, the soil 105 is then backfilled to its original level.

[0068]

[0044] An alternative basement waterproofing system 201 has a support membrane 221, which is essentially analogous to the protective membrane 121 of the previous example, but is arranged in reverse on a basement wall 207. A fleece 225 is applied to the support membrane 221 opposite the basement wall 207. Alternatively, individual spacers can also be arranged here (only the fleece is shown in Figure 3). The support membrane 221 is joined to a membrane connection 234 of a connection strip 233 by means of a connection area 222. A rain strip 231 is reversibly pressed into the connection strip 231, its function being essentially analogous to the rain strip 131 in the previous example. The fleece 225 forms a ventilation space behind the support membrane 221, which is essentially defined by the volume of the fleece 225.The studs 223 and 224 arranged on the support foil 221 serve to create a further ventilation space 229, with an additional protective foil 251 being applied facing away from the basement wall 207. The protective foil 251 has a termination 253 in an upper area, the termination 253 being angled relative to the protective foil 251 and extending below the rain strip 231. The ventilation space 229 thus creates, in particular, an additional protective layer that further prevents penetrating moisture.

[0069]

[0045] The installation of the basement waterproofing 201 is carried out analogously to the installation of the basement waterproofing 201 .

[0070]

[0046] The function of the connecting strip 233 in connection with a rain strip 231 is explained in detail below:

[0047] The connecting strip 233 has retaining pieces 236 which form a clamping groove 235 along a foil connection 234. Furthermore, interruptions 236 are arranged in the profile of the connecting strip 231 along its longitudinal extent, which are evenly spaced and distributed along its longitudinal extent. This forms corresponding flanges 261 which serve as a bearing surface for the support foil 221 in the connection area 222. The support foil 221 can thus be inserted into the respective areas of the clamping groove 235 and clamped.

[0071]

[0048] The interruptions 236 serve as ventilation passages for venting a ventilation space formed behind the support film 221 by the fleece 225 and additionally for venting the ventilation space 229.

[0072]

[0049] Reference is also made to support strips 226 (see illustration in Figure 5), which are arranged on the back of the support film 221 and can, for example, form a ventilation space behind the support film 221 as an alternative to the fleece 225.

[0073]

[0050] In this case, the studs 223 and 224 serve to create an additional distance and free space analogous to the above explanations, whereby the ventilation of the structure behind the support film 221, i.e. facing the wall, in particular the basement wall 207, is carried out.

[0074]

[0051] It should also be mentioned that corresponding open spaces, for example the air slot 135, can be closed by means of grilles or wire mesh to prevent, for example, the ingress of animals. Likewise, the examples described above can each also be supplemented with active ventilation, for example by means of electric fans (not shown), so that a forced removal of moisture is made possible.

[0075]

[0052] Let us now assume that the basement waterproofing 101 and 201 were fully effective in their function, but that heavy rain, flooding, or water damage in house 103 led to water ingress into the ventilation space 129 and / or 229, making technical venting and drying necessary. The procedure for this is explained in detail with regard to basement waterproofing 201:

[0076]

[0053] After removing the rain strip 231, a ventilation profile 701 is slid onto the connecting strip 233 in place of the rain strip 231 and fastened in the clamping groove 269 of the connecting strip 233 by means of a clamping profile 731. The ventilation profile has a front face 703 which, in the mounted position (see Figures 8 to 11), is arranged parallel to the support foil 221. A leg of the front face 703 extends at a right angle to the support foil 221 on its upper side.

[0077] 705 and on one underside a leg 707 in the direction of the basement waterproofing 201. The respective end regions of legs 705 and 707 form a respective sealing edge.

[0078] 706 and 708, which abut the connecting strip 233 and the support foil 221, form a substantially airtight connection, so that an interior space 721 of the ventilation profile 701 is fluid-conductingly connected to the ventilation chamber 229 via the ventilation openings 267. Furthermore, ventilation connections 711 and 715, and possibly other ventilation connections, are fluid-conductingly connected to the interior space 721. Air can then be blown in or extracted at the ventilation connections 711 and 715, as well as at other ventilation connections, for example, using a blower (not shown), so that a flow is created in the interior space 721 and also in the ventilation chamber 229, which carries away moisture.It should be noted that the interior 721 of the ventilation profile 701 along the basement wall 107 can also be equipped with barriers to prevent airflow, so that, for example, targeted air injection into one area of ​​the basement waterproofing 201 and targeted air extraction into another, laterally offset area of ​​the basement waterproofing 201 can be carried out. For this purpose, respective ventilation profiles 701 can also be used, which also have a seal at their respective end areas.
