Definitions
- the invention relates to a sealing element for a building joint, with a first carrier layer and a second carrier layer.
- the two carrier layers are essentially of the same length. Furthermore, at least one section of the first carrier layer and at least one section of the second carrier layer converge in a V-shape.
- V-shaped convergence means that at least one section of the first carrier layer is arranged at an acute angle relative to at least one section of the second carrier layer
- sealing elements are known from the prior art.
- the carrier layers running towards one another in a V-shape serve to provide the sealing element with a certain mobility, so that it can adapt to any relative movements of the boundary surfaces of the building joint that may occur. Such relative movements can result from settlement processes of the building in which the building joint is located.
- the mobility can be used to compensate for variations in the width of the building joint to be sealed.
- a sealing element of this type can therefore be used in building joints whose width varies within a certain range.
- EP 3 584 381 A1 discloses a sealing element which is made of an intumescent material and is therefore used for fire protection sealing.
- the sealing element from EP 3 584 381 A1 can have differently designed profiles, so that it can be used in different types of building joints.
- a multi-part seal structure is usually necessary.
- a sealing cord is known from WO 2017/207252 A1, which contains an intumescent material and is used for sealing against smoke gas, water and dust.
- the object of the present invention to specify a sealing element by means of which different sealing functions can be provided in a simple manner.
- the sealing element should be structurally simple so that it can be manufactured easily and inexpensively.
- it should be possible to install the sealing element in the building joint with little effort.
- a sealing element of the type mentioned at the outset in which a receiving space is formed between the first carrier layer and the second carrier layer and a functional material is received in the receiving space.
- a functional material is understood to be a material that fulfills a certain function in connection with the sealing of a building joint. Examples of such functions are fire protection, thermal insulation and sealing against moisture, foreign particles and air exchange. Foreign particles are z. B. Dust particles.
- a single functional material that fulfills one or more functions can be accommodated in the accommodation space. Of course, it is also possible to accommodate several functional materials in the accommodation space, each of which fulfills the same or different functions.
- Such a sealing element is structurally simple. As a result, it can be produced easily and inexpensively, in particular as an endless material.
- sealing elements can be easily adapted to different applications.
- the recording space can be completely or only partially filled with the functional material.
- the fact that at least sections of the carrier layers run towards one another in a V-shape means that the sealing element can be reliably placed against the boundary layers of the building joint.
- this shape makes it easier to insert the sealing element into the building joint, since the sections running towards one another in a V-shape act as insertion bevels.
- Such a sealing element can also be used for a wide range of joint widths without having to be modified for this purpose.
- the first backing layer and the second backing layer may comprise a polymeric material.
- they are therefore made of a plastic material, for example polyvinyl chloride.
- the carrier layers can comprise a fiber material.
- they can also have a metallic material or a composite material.
- the first carrier layer and the second carrier layer can comprise a paper or cardboard material and/or a cork material in the broadest sense. It is also conceivable that the first carrier layer and the second carrier layer have a wood material, in particular a bamboo material.
- the at least one section of the first carrier layer and the at least one section of the second carrier layer are connected to one another at their respective ends that are closer together.
- the first carrier layer and the second carrier layer are connected to one another in an elastically yielding manner.
- the sealing element is only open on one side. This makes it particularly easy to introduce a functional material into the receiving space and hold it there.
- the carrier layers connected to one another preferably form a one-piece carrier layer composite.
- An elastically flexible connection means that the sealing element can be elastically compressed in a width direction of the associated building joint. This facilitates insertion into the building joint.
- a further section of the first carrier layer and a further section of the second carrier layer can essentially run parallel to one another.
- Each of the further sections is in particular connected to one of the sections running towards one another in a V-shape, preferably connected in one piece.
- a relatively large receiving space can be created.
- a comparatively large amount of functional material can be accommodated therein.
- such a sealing element is designed to penetrate over a comparatively great depth into the building joint and to ensure sealing.
- the first carrier layer and the second carrier layer preferably converge as a whole in a V-shape.
- the sealing element is therefore particularly simple in construction and can be produced extremely easily.
- the carrier layers can be produced by means of an extrusion process.
- the carrier layers can be flat.
- a section of an outer surface of the first carrier layer forms a first contact surface for contact with a boundary surface of the construction joint and/or a section of an outer surface of the second carrier layer forms a second contact surface for contact with a boundary surface of the construction joint.
- the first carrier layer and the second carrier layer are thus directly, in particular without the interposition of further layers, in contact with the associated boundary surfaces of the building joint. This also makes the sealing element structurally simple.
- first contact surface and/or the second contact surface can be provided with an adhesive coating.
- an adhesive coating serves to increase the static friction between the carrier layer and the associated interface of the building joint.
- the adhesive coating serves to achieve improved adhesion of the carrier layer to an associated boundary surface of the building joint through adhesion. As a result, the sealing element is reliably held in the structural joint.
- At least one holding element for holding the sealing element is on the first contact surface and/or on the second contact surface provided in the building joint.
- the holding element is in particular a holding projection or a holding finger.
- the sealing element is also reliably held within the building joint by means of the at least one holding element.
- the holding element is deformed, for example, so that sections of the holding element get caught on the associated boundary surface of the building joint.
- the functional material includes an intumescent material.
- an intumescent material swells under the action of heat, i.e. increases its volume.
- the sealing element can ensure a particularly reliable fire protection seal. This is particularly true in relation to sealing against surfaces that are not ideally flat.
- the functional material includes a thermal insulation material. Heat transfer through the structural joint is thus reliably prevented or at least inhibited.
- the thermal insulation material includes, for example, mineral wool.
- the functional material can include a noise insulation material.
- the building joint can thus be insulated from an acoustic point of view.
- Such an insulation material can also include mineral wool.
- the functional material can also include a sealing material.
- a sealing material serves to seal against smoke, air, moisture, foreign particles and/or water. The building joint can thus be reliably sealed in this respect.
- the functional material rests against both the first carrier layer and the second carrier layer, with the functional material being elastically flexible. It can thus be the first carrier layer and the second carrier layer under elastic deformation of the Bring functional material together. As soon as the force applied for this is no longer effective, the carrier layers are moved back into their original position by the functional material elastically deforming back.
- the overall result is a sealing element that can be compressed in a dimension corresponding to a joint width, for example for insertion into a building joint. As a result, the sealing element can be introduced particularly easily into the building joint. The sealing element can then elastically deform back within the building joint, so that it comes to a reliable sealing contact with the boundary surfaces of the building joint.
- the deformation of the functional material can also lead to the sealing element being pulled into the structural joint.
- the functional material can have a higher elastic resilience than the carrier layers.
- the carrier layers are stiffer than the functional material.
- an elastic deformation of the sealing element can be influenced in a targeted manner with regard to the location of the elastic deformation and with regard to an associated direction of deformation.
- the sealing element can be configured in such a way that the carrier layers essentially do not deform elastically and thus the elastic deformation of the sealing element essentially results from an elastic deformation of the functional material.
- Such a deformation takes place in particular essentially over the entire length and/or the entire width of the functional material.
- the sealing element can be easily and reliably introduced into an associated building joint.
- a spring element which is separate from the functional material and connects the first carrier layer and the second carrier layer can be arranged in the receiving space.
- This spring element can be elastically compressed in that the first carrier layer and the second carrier layer are brought closer together.
- the advantage of using a spring element is that the actual functional material can be selected regardless of its elastic formability.
- a particularly high force can be achieved by means of a spring element, with which the Sealing element is pressed in the assembled state to associated interfaces of the building joint.
- a further variant provides that at least one of the ends of the carrier layers, which are further apart from one another in the cross-sectional view, is provided with a stop element for resting on an edge of the building joint.
- this stop element preferably protrudes away from the respective other carrier layer, ie outwards from the sealing element.
- Such a stop element prevents the sealing element from being pushed too far into the building joint. This results in a precise arrangement of the sealing element within the structural joint.
- a cover element for covering the receiving space can be arranged on at least one of the ends of the carrier layers that are further away from one another in the cross-sectional view.
- the cover element can start from one end of one of the carrier layers and extend in the direction of the respective other carrier layer, ie in the direction of the receiving space.
- the covering element can also be connected to the ends of both carrier layers.
- the covering element is then preferably elastically deformable.
- the cover element serves to protect the receiving space and the functional material arranged therein from dirt and/or moisture.
- the cover element can be attached to the at least one carrier layer as a solid body or can be sprayed in liquid form onto the functional material and the associated ends of the carrier layers.
- the covering element starts from only one of the carrier layers, it can extend beyond the respective other carrier layer.
- the cover element can then also act as a stop element in order to prevent the sealing element from being pushed in too far into a building joint.
- FIG. 1 shows a section of a sealing element according to the invention in a perspective view
- FIGS. 25 and 26 show additional variants of the sealing element according to the invention in cross-sections, the sealing element being cut along plane A in FIG. 1, and
- FIG. 1 shows a sealing element 10 which is designed to seal a building joint.
- It comprises a first carrier layer 12 and a second carrier layer 14.
- Both carrier layers 12, 14 are essentially planar.
- At least one section of an outer surface 13 of the first carrier layer 12 forms a first contact surface for contact with a boundary surface of the building joint.
- a section of an outer surface 15 of the second carrier layer 14 forms a second contact surface for contact with an interface of the building joint.
- the first carrier layer 12 and the second carrier layer 14 run towards one another as a whole in a V-shape in a cross-sectional view which is oriented perpendicularly to a longitudinal direction L of the sealing element 10 (cf. plane A).
- the two carrier layers 12, 14 are also essentially of the same length.
- This connection 16 is elastically flexible. Starting from the position shown in FIG. 1, the carrier layers 12, 14 can be elastically deformed in such a way that the two carrier layers 12, 14 are moved towards one another.
- a receiving space 18 Formed between the first carrier layer 12 and the second carrier layer 14 is a receiving space 18 in which a functional material 20 is received.
- FIG. 2 shows an embodiment in which the receiving space 18 is completely filled with a functional material 20 .
- the functional material 20 is thus in contact with both the first carrier layer 12 and the second carrier layer 14 .
- the functional material 20 is an intumescent material 22.
- the functional material 20 only partially fills the receiving space 18 . In this case, that area of the receiving space 18 which is oriented in the direction of the connection 16 is left free.
- FIG. 4 represents a variant of the embodiments according to FIGS. 2 and 3. Again, the same functional material 20 is used, which again only partially fills the receiving space 18 .
- the functional material 20 is now a thermal insulation material 24 which is also a noise insulation material 26 at the same time.
- the functional material 20 is mineral wool.
- the receiving space 18 is again completely filled with the functional material 20 .
- a cover element 28 is now additionally provided, which connects the ends of the carrier layers 12, 14 that are further away from each other and covers the receiving space 18.
- the functional material 20 is thus protected against the effects of dirt and moisture.
- the covering element 28 can also be shaped more elastically, so that it does not stand in the way of the carrier layers 12, 14 moving towards one another.
- the functional material 20 is again the intumescent material 22.
- a first strip is applied to the first carrier layer 12 .
- a second strip of the functional material 20 is arranged on the second carrier layer 14 .
- the receiving space 18 is not filled between the strips of the functional material 20 .
- the embodiment from Figure 7 represents a further development of the embodiment from Figure 6.
- a further functional material 20 is arranged between the strips of the intumescent material 22 .

- the additional functional material 20 can be a thermal insulation material 24 , a noise insulation material 26 or a sealing material 30 .
- FIG. 8 The embodiment according to FIG. 8 is based on the embodiment according to FIG.
- a spring element 32 which is separate from the functional materials 20 and connects the first carrier layer 12 and the second carrier layer 14 is arranged in the receiving space 18 .
- the carrier layers 12, 14 can be elastically returned to their starting position by the spring element 32 after they have been moved towards one another in the vertical direction in FIG.
- the spring element 32 thus defines a pressing force of the sealing element 10 in its installed position.

- a cover element 28 is now provided again, which, however, is only connected to one end of the second carrier layer 14 in the embodiment according to FIG.
- the cover element 28 extends over the receiving space 18 and over one end of the first carrier layer 12 .
- the receiving space 18 is reliably covered and thus protected from the undesirable effects of dirt.
- the section of the cover element 28 that protrudes beyond the first carrier layer 12 also acts as a stop element 36.
- the sealing element 10 according to FIG. 11 has a combined stop element 36 and cover element 28 .
- the embodiment according to FIG. 12 is also based on the embodiment according to FIG.
- three holding elements 38 in the form of holding fingers 40 are provided on the outer surfaces 13, 15 in each case.
- the retaining fingers 40 When inserted into an associated building joint, the retaining fingers 40 are slightly deformed, so that they catch on the boundary surfaces of the building joint.
- FIG. 13 represents a variant of the embodiment according to FIG. Figures 14 to 24 show further embodiments of the sealing element 10.
- the carrier layers 12, 14 are designed in such a way that only sections 12a, 14a thereof run towards one another in a V-shape. Further sections 12b, 14b of the first carrier layer 12 and the second carrier layer 14 run essentially parallel to one another.

- the variant according to Figure 19 combines the embodiments according to Figures 17 and 18.
- the embodiment according to FIG. 20 is based on the embodiment according to FIG.
- the embodiment according to FIG. 21 differs from the variant from FIG. 20 in that an additional functional material 20 is arranged in the remaining sections of the receiving space 18 .
- a stop element 36 is now arranged at the ends of the carrier layers 12, 14 that are further away from one another.
- the stop elements 36 each project outwards away from the sealing element 10 .
- stop elements 36 The function of the stop elements 36 is as already explained in connection with FIG.
