Description

The invention relates to an expansion joint tape for the permanent, reliable sealing of joints, such as expansion joints between or in structures and/or parts thereof, in particular expansion joints between tunnel segments of e.g. railway and road tunnels, with an elastic, preferably plastic-like and/or rubber-like, material, with a sealing strip, wherein the sealing strip has continuously extending cavities running along its central longitudinal axis within the same - a joint sealing device for the permanent, reliable sealing of joints between or in structures and/or the same, in tunnel structures and the use thereof.

In the current state of the art, for example, to seal an expansion joint between two tunnel segments arranged one behind the other at a distance, a strand-shaped sealing profile made of an elastomeric plastic, for example rubber or rubber-like plastic, is used, which can have open or closed grooves running lengthways on its base side and usually also channels running lengthways. For example, in tunnel construction, e.g. using the tubbing construction method, a conventional sealing profile is inserted or squeezed under pressure into the inner sides of the tunnel segments, which are milled out to form a circumferential groove and are located opposite the pressurized water side.

Tunnel segments are also understood to be those which can be designed with partially circular or fully circular, such as ring-shaped, walls, also called tunnel segment walls, which can be aligned one behind the other along their common central longitudinal axis or with a matching central longitudinal axis, so that the front sides of their walls, which can be aligned transversely to the central longitudinal axis, are adjacent to one another or can be described as opposite one another, forming an expansion joint, also called a joint or gap. The longitudinal extension of the tunnel segments is also understood to mean the extension along or parallel to the central longitudinal axis of the tunnel segments. The front sides of the walls of two tunnel segments arranged in a row can be spaced apart to such an extent that the variable distances between the adjacent front sides that occur as a result of relative movements that can be observed in laid tunnel segments, such as expansion, also known as drifting apart, compression, also known as moving towards each other, and/or strains, also known as opposing movements, along the vertical, are still given sufficient space by the expansion joint common to the front sides. However, the state of the art only inadequately solves the problem of sealing the expansion joint of the two adjacent tunnel segments when one of the aforementioned movements occurs and when they interact.

The conventional sealing profile, which is placed against the segment wall which has been freed from reinforcement or from a part of it and is connected to it by means of a filling between the segment wall and the sealing profile, does not provide adequate sealing of the expansion joint in the interaction of the aforementioned movements of the tunnel segments or of one of them; the inadequate sealing is independent of whether the conventional sealing profile is placed against the segment wall which has been freed from reinforcement and faces the pressurised water side, also referred to as the outside of the segment wall, or against the segment wall which has been freed from reinforcement and faces away from the pressurised water side, also referred to as the inside of the segment wall.

If only one of the aforementioned movements of the tunnel segments occurs, a conventional sealing profile applied in this way proves to be insufficiently reliable for sealing the expansion joints against the penetration of, for example, moisture or pressurized water from the pressurized water side.

Such a sealing profile for tunnel segments provided with a circumferential groove has open or closed grooves running in the longitudinal direction on its base side and usually hollow chambers also running in the longitudinal direction. The sealing profile has at least one support foot running in the longitudinal direction of the profile on its base side, which is inserted in an additional circumferential anchoring groove. The conventional sealing profile, which is inserted into this groove with the application of force, seals the expansion joint in the direction of the inside milled out to form a groove under the influence of a force, since under the influence of the force the gap distance between two tunnel segments is reduced as a result of the movement of the tunnel segments relative to one another. This presses the conventional sealing profile together, which seals the gap and thus the joint. The conventional sealing profile is pressed into the groove in such a way that it is arranged in an approximately arcuate manner around the central longitudinal axis common to the tunnel segments or around the central longitudinal axis common to the interior space delimited by the tunnel segments.

However, the disadvantage is that the tunnel segments not only move towards each other, but as a result of soil settlement the tunnel segments can also become increasingly further apart from each other, so that the conventional sealing profile is no longer pressed together due to the effect of a force and thus seals the expansion joint to a steadily decreasing extent, which disadvantage is to be avoided especially when sealing tunnel segments of, for example, railway and road tunnels.

Due to the lack of compression of the sealing profile, the area between the conventional sealing profile and the groove cheeks that laterally limit the groove cheek becomes leaky for water that presses from the pressurized water side, i.e. from the outside, towards the interior of the tunnel segments.

This is how the EP368174 Phönix Aktiengesellschaft, Hamburg, was not offered the opportunity to adequately and permanently seal the widening expansion joint between two tunnel segments as a result of the tunnel segments becoming increasingly spaced apart due to ground displacement.

Due to the danger of the tunnel segments becoming increasingly spaced apart, it is necessary to constantly check the areas of the expansion joints between two tunnel segments in order to replace the conventional sealing profiles if water enters the interior of the tunnel segments from the outside via the pressurized water side, which is to be avoided.

Therefore, it is also an object of the invention to provide an expansion joint tape which permanently and reliably seals the joint and thus the expansion joints between two tunnel segments, regardless of whether the tunnel segments approach each other or move away from each other.

In addition, an expansion joint tape and a joint sealing arrangement are to be provided, which offer sufficient safeguards to eliminate the penetration of groundwater via the pressurized water side through the interaction of various components.

It is also evident that in the state of the art, sealing profiles are inserted into the expansion joints as external sealing profiles, so that their longitudinal center planes are aligned transversely or perpendicularly to the longitudinal extension of the tunnel segments, but one of the long sides of which is arranged parallel to the central longitudinal axis of the tunnel segments. In this arrangement, the protruding webs formed on the side of the conventional sealing profiles are embedded in a mass to fix the conventional sealing profile, but it turns out that when the tunnel segments move apart from one another, the expansion joint widens due to the increasing spacing of the joint sides that laterally limit the expansion joint, so that the conventional sealing profile is overstretched in the area adjacent to the expansion joint, and the overstress leads to gaps and cracks. Due to the gaps and cracks, water flows from the pressurized water side through the expansion joint and through the gaps and cracks into the interior of the tunnel segments.

The task is therefore to provide an expansion joint tape and a joint sealing arrangement which are tolerant to expansion or over-expansion of narrowly defined areas when tunnel segments drift apart and which seal reliably.

The arrangement of sealing profiles that is usually known in the prior art, when these are arranged, for example as internal ones, with their longitudinal center planes transverse and one of their long sides parallel to the longitudinal extension of the tunnel segments, makes it necessary to remove part of the reinforcement of the tunnel segments that is adjacent to the expansion joint or that is next to the expansion joint; the removal of at least part of the reinforcement is essential so that the sealing profiles with their webs formed on their one long sides are completely embedded in the concrete-like mass with sufficient filling of the gap, which gap is located between the one long sides of the conventional sealing profiles and the sides of neighboring tunnel segments that have been cleared of reinforcement and are either adjacent to the pressurized water side or arranged opposite it.

Therefore, it is also the task of the expansion joint tape and the joint sealing arrangement to be arranged in the expansion joint in such a way that the reinforcement, which in the area of the expansion joint, must be removed so that the statics and the pressurisation properties of the tunnel segments remain unchanged without interfering with the reinforcement.

When components are joined together, joints are created. These must be designed professionally, and the joint sealing must meet the requirements of heat, sound, moisture and fire protection. Standing joints are joints in which little or no movement occurs. Movement joints are pre-planned interruptions in components. The width of a movement joint can change. When the temperature rises, e.g. due to sunlight, the components of the building expand and the movement joints become narrower, but the opposite process is often observed when cold snaps occur. Construction joints, which also need to be sealed, occur if, for example, an interruption is necessary during the construction of a building. Construction joints also occur when building materials change, e.g. prefabricated columns and masonry.

Joint sealants are traditionally used to seal joints. Joint tapes are particularly suitable as joint sealants. These are the preferred choice in concrete construction. They can be made of an elastic plastic and can be easily deformed. The conventional joint tapes used to bridge the joints between buildings or parts of them, also known as expansion or expansion joint tapes, are cast into the concrete with their edge-side side bands.

The prior art discloses a joint tape which consists of a deformable, channel-like central part and strips adjoining the central part on the side, on which strip-like beads with a mushroom-like cross-section are formed on one side. The strips adjoining the sides are embedded in concrete to firmly couple the side bands to the concrete. However, it turns out that the structural parts carry out relative movements to one another. The relative movements are shown in a so-called expansion due to drifting apart. of the structural parts from each other. The drifting apart of the structural parts from each other causes a high material stress on the middle part of the joint tape as a result of the expansion, so that the appearance of gaps and cracks can be observed in the middle part of the conventional joint tape.

Likewise, compression of the structural parts relative to one another leads to compression of the middle section due to the movement of the structural parts relative to one another, so that leaks in the middle section increasingly occur as a result of crushing. The leaks caused by cracks and gaps allow moisture to penetrate and water to penetrate via water bridges into the interior of the joint sealed by the conventional joint tape, so that moisture pockets and cold bridges become established in the structure.

The stress on the conventional joint tape is increasingly increased by the relative movements of the structural parts to one another along the vertical, so that the expansion capacity of the conventional joint tape, which is limited to the central part, is not sufficient to prevent, under adverse conditions, a tearing of the central part from the side bands or at least a tear in the area of the central part or in the transition area from the central part to the side bands.

Another conventional joint tape comprises a central piece, two side bands formed onto the central piece and rows of webs formed onto the side bands. The conventional joint tape can bridge the joints between two components without the need to couple the joint tape to the components using additional holding devices, since the conventional joint tape is held in the concrete walls of the components by means of the rows of webs in the concrete. However, the rows of webs arranged in the concrete of the concrete walls severely limit the flexibility of the conventional joint tape, so that the conventional joint tape cannot expand evenly in all directions. The expansion of the joint tape and the uniform expansion are nevertheless essential in order to bridge the joints between the components permanently and tightly during relative movements of the structural parts to one another.

The publication considered to be the next most relevant DE 20 2018 000 172 U1 The expansion joint tape disclosed is intended to seal the cracks and gaps caused by compression of the structural parts relative to one another as a result of the movement of the structural parts as relative movements, by stopping the penetration of water creeping along through these cracks and gaps due to the high circulation path of the conventional expansion joint tape.

This in FR 3017684 A1 The expansion joint tape disclosed has a plurality of polygonal hollow chambers that run along the strand-shaped expansion joint tape.

The BE 549 247 A The joint tape disclosed has a central piece, side bands formed on the central piece and several webs formed with their broad base on the top and bottom of the side bands and is deformable.

The US 2 901 904 A The joint seal described, which has a central piece and side bands with webs formed on the sides of the central piece, is not suitable for permanently sealing the gap bridging between the two components due to its inability to expand evenly.

That the FR 1 248 986 A The joint tape profile on which it is based, with a central part and side bands formed on both sides of the central part as well as webs formed on the top and bottom of the same, is only slightly deformable, since the central part is solid and the webs merge with their base into the side bands, so that the conventional The joint tape profile can be easily pulled out of the components and, moreover, the conventional joint tape profile does not provide any counterforce to the pull-out force acting on the conventional joint tape profile caused by the relative movements of the components.

Therefore, an expansion joint tape should be provided which is characterized by a higher and uniform expansion capacity in all directions and remains securely in place in the adjacent structural parts and permanently bridges the joint between the structural parts due to its expansion capacity.

The object of the invention is to provide an expansion joint tape which is tolerant of the relative movements of building components to one another while providing sufficiently permanent sealing of the joint between them, which can be attributed to various causes, such as temperature changes, shrinkage of the concrete, rigidity of the construction, type of building materials used and the like.

The expansion joint tape and the joint sealing arrangement should offer such a large surface area in the event of liquid penetration that the creeping of liquids into the gap area bridging the joint and the expansion joint tape is sufficiently prevented.

In addition, the sealing parts of the expansion joint tape and the joint sealing arrangement, which are firmly embedded in the parts of the structure, should move along with the structural parts moving away from each other without gaps and cracks occurring in expansion areas.

A compression band arrangement for permanent, reliable sealing of joints, such as edge joint areas, between or in structures, preferably in Tunnel structures, and/or parts thereof, to the outside or inside.

Furthermore, the expansion joint tape and the joint sealing arrangement to be provided should have a tensile strength in the expansion or strain area between the sealing strip and the webs formed on the sealing strip.

In the event of heavy stress due to expansion, a sufficiently liquid-tight seal between the structural parts of the building should also be possible, preventing the penetration of water from the outside into the gap and vice versa.

The expansion joint tape and the joint sealing arrangement to be provided should also prevent the webs from tearing out of the concrete when they are subjected to heavy stress as a result of stretching, compression and strain.

The expansion joint tape and construction joint tape provided should also be used.

The expansion joint tape and the joint sealing arrangement should also be able to bridge the large gap widths between structural components, such as between tunnel structural components, caused by seismic events such as earthquakes or high-speed rail traffic, without impairing the waterproofing, soundproofing and thermal insulation properties of the expansion joint tape and the compression band arrangement.

In addition, the expansion joint tape and the joint sealing arrangement to be provided should also seal the gap between the structures against high water pressure.

Likewise, the expansion joint tape to be provided and the joint sealing arrangement should show compensating movements that are largely adapted to the load and distributed over the expansion joint tape in order to avoid material fatigue caused by point loading.

Likewise, the expansion joint tape to be provided and the joint sealing arrangement should enable such a sufficient watertight connection between the concrete and the cast-in side band that if defects occur in the concrete, such as gravel nests or cavities, no tearing or cracking is observed in the area of the side band of the joint tape.

The object of the invention is to comprehensively seal the joint or expansion joint located between the front sides of the walls of the tunnel segments, both against pressurized water pressing on the tunnel segments from the outside and against water or moisture that has already penetrated the joint in order to prevent it from passing through or entering the interior of the tunnel segment via the joint or expansion joint. Therefore, an expansion joint tape or a joint sealing device should be provided so that both the expansion joint tape permanently seals the area of the joint or expansion joint facing the pressurized water side, and other measures and devices must be provided that offer additional security and support for the aforementioned sealing, since safety-related reasons also require sealing directly against pressurized water penetration, especially in the event of serious accidents such as earthquakes, and the additional provision of further sealing measures in order to also permanently seal the area of the joint facing the interior of the tunnel segment.

Therefore, the invention is not only intended to provide an expansion joint tape with special technical features, but also to be able to combine the expansion joint tape with additional sealing devices, which, for example, as a joint sealing device, the area the joint or expansion joint which faces the interior of the tunnel segment, so that both areas of the joint or expansion joint, namely the area facing the pressurized water side and the area facing away from the pressurized water side, are sealed.

It is apparent that, particularly in the event of earthquakes, vibrations caused by railway or motor vehicle traffic, and other accidents, the joint or expansion joint between the tunnel walls or the walls of the tunnel segments that are adjacent to one another is not sealed by conventional sealing tapes due to forces arising from excessive tensile stresses that can act on the expansion joint tape and/or the joint sealing device in accidents of this type, and due to mechanical pressure acting on the conventional sealing tape.

The object is solved by the main claim 1 and the auxiliary claims. The dependent claims relate to preferred embodiments and further developments of the invention.

Due to the excellent and permanently reliable sealing of expansion joints between tunnel segments under a wide range of movements Due to the inherent disadvantages of expansion joints, such as drifting apart, compression, strain and the almost complete elimination of controls, the expansion joint tape according to the invention is particularly suitable as an internal sealing arrangement for tunnel construction, for example for railway and road tunnels.

Until now, the state of the art has been to apply conventional expansion joint tapes or sealing tapes with their surfaces flatly from the outside against the walls of the tunnel segments, bridging the joint gap. However, the conventional sealing has shown itself to be particularly problematic in the event of an emergency such as earthquakes or strong vibrations that can affect the tunnel segments, causing the tunnel segments to shift and leaks to occur.

The invention departs from this conventional solution principle and takes a completely different approach in that the expansion joint tape and the joint sealing device, which also includes the expansion joint tape, are arranged in the joint or expansion joint, which are laterally delimited by the two end faces of the adjacent walls of the tunnel segments, in such a way that the expansion joint tape is no longer arranged flat against the tunnel walls or their outer sides, which face the pressurized water side, as in the prior art, but is arranged in the expansion joint transversely to the longitudinal extension of the tunnel segments. Only the arrangement and alignment of the expansion joint tape and the joint sealing device with the expansion joint tape with the sides, the sealing strip transverse to the longitudinal extension of the tunnel segments and the arrangement of the sealing strip in such a way that one edge area faces away from the pressurized water side and faces the interior of the tunnel segments, as well as the other edge area of the sealing strip facing the pressurized water side, so that the central longitudinal axis of the sealing strip is also transverse to the longitudinal extension of the tunnel segments, enable the permanent sealing of the joint between the two walls of the adjacent tunnel segments. It also shows that the joint The gap that is to be bridged, which may have or take on a different gap width in the event of vibration, earthquakes and other accidents, is sealed by the expansion joint tape and the joint sealing device with its expansion joint tape. By arranging the expansion joint tape, in contrast to the state of the art, no longer with its sides along the longitudinal extension, but diametrically opposite to the conventional teaching across the longitudinal extension of the tunnel segments, a completely different solution is taken from the expansion joint tape and the joint sealing device with the expansion joint tape for sealing between tunnel segments; this two-sided sealing of the joint and the different type of sealing of the joint are unexpectedly characterized by reliable durability and high load-bearing capacity.

In addition, the sealing is supported by the fact that the expansion joint tape can enclose the joint sealing device or can be combined with it.

The combination of the expansion joint tape with the joint sealing device can also be referred to as a joint sealing device with the expansion joint tape or part thereof. The inclusion of the expansion joint tape with a joint sealing device or the combination of the expansion joint tape with the joint sealing device is also understood as a joint sealing device with the expansion joint tape and the joint sealing device.

The clever interaction of the expansion joint tape with the joint sealing device enables, on the one hand, a significant increase in the circulation distance of the water, if in the event of a particularly serious accident, the water were to penetrate into the joint via the pressure water side, via the other edge area of the sealing strip of the expansion joint tape facing the pressure water side. This shows that that the circulation distance of the water increases significantly due to the large number of webs, and the penetration of water is further prevented by providing the head areas of the webs with expansion bands that swell or can swell in the presence of water, so that no further penetration of water occurs between the expansion joint band and the front side. However, since the extent of accidents cannot be predicted and technical precautions must be taken against the consequences of these, the use of the combination of the expansion joint band with a joint sealing device or the joint sealing device in the area facing away from the pressurized water side supports the sealing of the joint.

The joint sealing device or the expansion joint tape with joint sealing device cleverly counteracts the leak. Therefore, due to the combination and clever interaction of the expansion joint tape and joint sealing device, both can be summarized as a joint sealing device as a generic term. The joint sealing device therefore takes a solution path that surprisingly provides the highest level of sealing due to the expansion joint tape and joint sealing device included in the joint sealing device.

The above and following designs of the expansion joint tape and the joint sealing device or sealing arrangement and the joint sealing tape preferably relate to those in the unloaded or relaxed state of the same. At least one edge region of the sealing strip of the expansion joint tape extends with a strip that protrudes beyond the side of the webs facing the edge region, forming a hollow chamber that preferably extends parallel to the central longitudinal axis. The hollow chamber is advantageously pentagonal in cross section. The hollow chamber can be designed as a three-, four-, six- or multiple-cornered polygon, the pentagonal polygon having sides, which can have matching lengths. The hollow chamber can also be designed as a polygon in cross-section, which is convex or concave. For example, if every connecting line between any two points of the polygon runs inside it, it is also referred to as a convex polygon. The hollow chamber can also be designed as a concave polygon, whereby the concave polygon can be characterized by corners protruding into its interior. The sealing arrangement with tunnel segments can also be understood as a joint sealing device.

The hollow chamber is a polygon in cross-section, with one corner having two sides of equal length extending into the interior of the polygon, two opposite sides being aligned parallel to one another or approximately parallel to one another, and the corner extending into the interior of the polygon being equally spaced from the two sides aligned parallel to one another.

The edge area of the sealing strip is designed as a strip or nose that protrudes beyond the web sides of the edge webs of the sides of the sealing strip facing away from the central longitudinal axis; the nose advantageously runs as a strip-shaped one along the central longitudinal axis of the sealing strip. In a further embodiment of the expansion joint strip, the nose has a hollow chamber that can be designed in cross-section as a, e.g., square, polygon, e.g. as a deltoid or kite. If the hollow chamber is designed as a deltoid, the diagonals can be perpendicular to each other in cross-section; one of them is the axis of symmetry and breaks the deltoid down into two congruent triangles, while the other runs outside the quadrilateral and forms two isosceles triangles together with the two equal sides or neighboring sides.

In the embodiment of the hollow chamber as a pentagonal polygon, the polygon can also be designed as a so-called overlapping polygon. In the design of the polygon A particularly preferred hexagonal polygon is one with two corners that engage into the interior of the polygon in cross-section and that can be opposite each other, so that the polygon can have an X-shaped configuration in cross-section. The sides that form the corners can be of equal length. The sides of the polygon that are opposite the corners that engage into the interior, here in the form of a hexagonal polygon, can be curved outwards, i.e. towards the sides on which the webs are formed, in an arc shape, such as a part-circle, and can have matching lengths, for example. In a special configuration, the cavity of the sealing strip that faces the hollow chamber is also designed such that the cavity is designed as a pentagonal polygon with a corner that either engages into the interior of the cavity or is directed towards the hollow chamber of the nose or the edge area. A particularly suitable design of the expansion joint strip is one in which the corner of the cavity closest to the hollow chamber has sides of equal length and can be congruent with the corner of the four-, five- or hexagonal polygon which extends into the interior and faces the cavity.

Likewise, the spaced-apart sides of the polygon, which also delimit the cavity, can be arched, at least partially circular.

In the expansion joint tape or the joint sealing device with the expansion joint tape, the cavity of the sealing strip which is adjacent to the hollow chamber of the edge region of the sealing strip can have a side facing the hollow chamber of the edge region, which in cross section tapers towards this edge region, i.e. outwards, preferably enclosing the same angle which corresponds to the angle of the sides which engage in the interior of the polygon to form the corner, or can be curved towards this edge region.

In one embodiment of the expansion joint tape or the joint sealing device with the expansion joint tape, the expansion joint tape is inserted into the expansion joint of two adjacent tunnel segments to provide the sealing arrangement in such a way that the edge region, which has the hollow chamber, preferably polygonal in cross-section, borders with its outer side on the outer sides of the walls of the tunnel segments. For example, the outer side of this edge region of the expansion joint tape can also be aligned and/or flush with the outer sides delimiting the expansion joint, such as the other segment wall outer sides of the tunnel segments, e.g. those facing the pressurized water side, or at least only slightly spaced from them. The term "aligned" means lying along or in a straight line; the term "flush" means lying on the same level.

The expansion joint tape or the joint sealing device with its expansion joint tape can preferably be arranged in the expansion joint in such a way that its central longitudinal axis is aligned transversely to the longitudinal extension or to the, advantageously common, central longitudinal axis of the tunnel segments or their interiors. Likewise, the longitudinal center plane of the expansion joint tape or the joint sealing device with its expansion joint tape can be aligned parallel to the longitudinal extension. In the sense of the invention, the longitudinal center plane can also be understood as the plane that runs parallel to the central longitudinal axis of the strand-shaped expansion joint tape and/or can be equally spaced from the two outer sides of the edge regions of the sealing strip of the expansion joint tape and/or can be aligned perpendicularly to at least one side of the sealing strip on which the webs are formed, which side is called the longitudinal side because of its greater longitudinal extension compared to the side, also called the transverse side, of the edge regions.

The sealing arrangement and the joint sealing device with its expansion joint tape are characterized by the particularly advantageous design of the expansion joint tape, which is a clear departure from the state of the art in that the expansion joint tape is inserted into the expansion joint without interfering with the reinforcement of the tunnel segments, breaking it open or partially destroying it; instead, it is only necessary to attach the expansion joint tape with its webs to the front sides that border the expansion joint or at least - depending on the requirements on site - to arrange it at a predetermined distance from them and to embed it in a conventional mass, for example a cement-like or concrete-like or mortar-like mass, so that, for example, the webs of the expansion joint tape are embedded in the mass on all sides. By embedding the webs in the mass, the expansion joint tape and its webs are effectively prevented from being pulled out if the tunnel segments drift apart. Pulling them out of the mass is made significantly more difficult by the webs provided with swelling bands.

Therefore, the mushroom-shaped head areas support the tight fit of the expansion joint tape in the mass. The head areas of the webs, which are provided with expansion tapes, also significantly increase the tight fit of the expansion joint tape of the sealing arrangement in the mass.

• sowohl bei Bewegung der Tunnelsegmente zueinander,
• als auch bei deren Wegbewegungen voneinander,
• das Dehnungsfugenband in der Masse ortsfest verbleibt und weiterhin hinreichend gedehnt werden kann.

In addition, the advantage is that

• both when the tunnel segments move towards each other,
• as well as their movements away from each other,
• the expansion joint tape remains stationary in the mass and can continue to be sufficiently stretched.

It is a surprising success of the sealing arrangement and the joint sealing device with its expansion joint tape, for example with the expansion joint tape inside the expansion joint, that by designing the edge area with at least one hollow chamber in longitudinal extension to the central longitudinal axis of the strand-shaped expansion joint strip, the design of the hollow chamber as a polygon with a corner engaging into the interior of the polygon, the edge region is tolerant of expansions due to the tunnel segments drifting apart as well as pressures due to movements of the tunnel segments relative to one another, while maintaining sufficient sealing of the expansion joint precisely in the area closest to the pressurized water side, which is primarily relevant for moisture and water tightness due to the increase in elasticity of the edge region of the sealing strip designed as a strip-shaped, strand-shaped nose due to the specially designed polygonal hollow chamber and due to the resulting excellent sealing of the nose on both sides against the end faces delimiting the expansion joint, which is unexpected.

The skilful interaction of the features of the sealing arrangement or the joint sealing device with its expansion joint tape, in particular the special design of the other edge area of the sealing strip of the expansion joint tape and its arrangement close to the pressure water side, with each other in the expansion joint of two adjacent or opposite tunnel segments and their front sides ensures, in a permanent and for the expert unexpected way, the seal between the expansion joint tape on the one hand and the front side of the wall or the pressed mass resting on the expansion joint tape on the other hand, so that a reliable liquid and moisture seal is established between two laid tunnel segments in the presence of the relative movements to be observed, such as expansion (drifting apart), compression (movement towards each other) and / or strains (opposite movements along the vertical).

• die gegenüberliegenden Randbereiche der Dichtungsleiste in Richtung zu den den Innenräumen der Tunnelsegmente zugewandten Innenseiten der Wände und den den Innenräumen der Tunnelsegmente abgewandten Außenseiten der Wände der Tunnelsegmente ausgerichtet sind.

It also appears that the sealing strip of the expansion joint tape and the joint sealing device with its expansion joint tape or the sealing arrangement, in contrast to the state of the art, with its longitudinal center plane not transversely and with their sides provided with webs not parallel to the longitudinal extension of the tunnel segments, e.g. on the outside, so that the sides of the conventional expansion joint strips facing the walls are aligned parallel to the longitudinal extension and the central longitudinal axis of the tunnel segments; rather, the special sealing is shown when the sealing strip of the expansion joint strip of the sealing arrangement and the joint sealing device with its expansion joint strip with

• their longitudinal center plane along the longitudinal extension of the tunnel segments and/or
• with its web-provided sides arranged transversely to the longitudinal extension of the tunnel segments, so that
• the centre transverse axis of the sealing strip is aligned transversely to the longitudinal extension and to the centre longitudinal axis of the tunnel segments and/or
• the webs of the sealing strip are aligned parallel to the longitudinal extension and the central longitudinal axis of the tunnel segments and/or
• the centre longitudinal axis of the sealing strip is aligned transversely to the longitudinal extension and to the centre longitudinal axis of the tunnel segments and/or
• the opposite edge regions of the sealing strip are aligned towards the inner sides of the walls facing the interior spaces of the tunnel segments and the outer sides of the walls of the tunnel segments facing away from the interior spaces of the tunnel segments.

In a further embodiment of the sealing arrangement or the joint sealing device with its expansion joint tape, a strand-shaped joint sealing tape is arranged in the expansion joint at a distance from the edge area facing away from the pressurized water side, on or in the area of the inner side facing the interior of the tunnel segments and can at least partially delimit them, which joint sealing tape is U-shaped in cross section and has webs formed on the outer sides of its legs, which merge into the section connecting the two legs. These webs can be like the webs of the sealing strip of the expansion joint tape be designed, e.g. be mushroom-shaped in their head area, also accommodate expansion bands in the head area and have projections. The space delimited by the legs and the section of the joint sealing band and/or the space of the expansion joint between the expansion joint band and the joint sealing band can accommodate filler material, plastic-like materials that contain plastics that swell in the presence of water, and/or polystyrene or the like.

It is shown that the expansion joint tape, the joint sealing device with its expansion joint tape or the sealing arrangement, which has the expansion joint tape, the joint sealing tape and/or the compression tape arrangement, prevent leaks when the tunnel segments drift apart and offer a sufficiently high resistance to the penetration of water via the pressurized water side towards the interior of the tunnel segments, since the circulation path for water and moisture around the webs and the projections and around the edge area having the hollow chamber, which can also have projections, is significantly increased, the interaction of which, apart from the presence of the projections formed on the webs, on the outside of the sealing strip and on the outside of the edge area, is noticeably increased by the special spatial design of the edge area and its sealing success against the pressurized water side due to its preferably square or pentagonal, polygonal hollow chamber and its special conforming or conforming property to the expansion joint and Humidity side.

The way the webs are designed and the head areas of the webs are provided with expansion bands also supports the sealing of the expansion joints of the adjacent tunnel segments, thus ensuring sufficient protection and permanent and reliable sealing of the expansion joint between the tunnel segments.

• die der Fachmann kennt, ohne dass die der Dehnungsfuge benachbarte Bewehrung der Tunnelsegmente im Gegensatz zum Stand der Technik im Bereich des Ansetzens der Dehnungsfugenbänder hätte beseitigt werden müssen auf beiden Seiten der Tunnelsegmente.

In addition, it is advantageous that the joint sealing device with its expansion joint tape and the sealing arrangement only requires the attachment or arrangement of the expansion joint tape with the sealing strip between the expansion joint, embedding it with its webs in a conventional mass and filling the remaining space with a conventional filling mass between

• the joint sealing tape and the edge area of the sealing strip facing away from the pressure water side
  and or
• the compression band arrangement and the edge area of the sealing strip facing away from the pressurized water side,
• which is known to the person skilled in the art, without the reinforcement of the tunnel segments adjacent to the expansion joint having to be removed in the area where the expansion joint strips are attached on both sides of the tunnel segments, in contrast to the state of the art.

Conventional rigid foams containing, for example, polystyrene, polyurethane, polyvinyl chloride, their derivatives, flexible foams, etc. and the panels made with them are suitable as fillers for this additional space. The filler can also contain thickening or swelling agents, which can be organic natural substances, organic modified natural substances, organic fully synthetic and/or inorganic substances, which can correspond to those for swelling tapes, and are listed below.

By attaching or applying the expansion joint tapes, the disadvantage to be considered as it is observed in the prior art, namely the removal of part of the reinforcement in the area of the expansion joints, is avoided and, in addition, the joint sealing tape or the compression tape arrangement is advantageously additionally attached to the side of the expansion joint opposite the pressurized water side as an additional safeguard against leaks.

A method for reliably and permanently sealing a joint between concrete walls is characterized in that

• a protective shoe is placed against one side of the expansion joint strip to accommodate the webs in pre-formed web spaces of the protective shoe and
• Wooden slats are placed against the edges of the expansion joint tape to protect the edges of the expansion joint tape from damage,
• the panelled space containing the other side area of the expansion joint tape with the webs and a steel reinforcement is poured with concrete,
• after the concrete has hardened, the protective shoe is removed and the panelled space containing one side area of the expansion joint tape with the webs and a steel reinforcement is poured with concrete,
• After the concrete has hardened, the wooden slats are removed and sealing strips are preferably placed against the edges of the expansion joint tape.

The expansion joint tape can have a ratio of the circulation path or distance to the thickness of the sealing strip in a range of 10.0 to 30.0, preferably 15.0 to 25.0, even more preferably 21.67. The circulation path or distance is also understood to mean the sum of the thicknesses of the sealing strips on both sides, the distances of the sides of the sealing strip between the webs, the widths of the webs, the lengths of the web sides of the webs, preferably on both sides of the sealing strip or the expansion joint tape. The circulation path or distance can also be understood to mean, in cross section, the sum of the distances of the sides of the sealing strip between the webs, the widths of the webs or the widths of the head areas, the lengths of the web sides of the webs, preferably on one side relative to a Side or bilaterally related to both sides of the sealing strip or expansion joint tape. The term "circumferential path or distance" can also be understood as the sum of the distances between the sides of the sealing strip between the webs, the circumferences of the head areas bordering the web sides, the lengths of the web sides of the webs, preferably unilaterally related to one side or bilaterally related to both sides of the sealing strip or expansion joint tape.

In a further embodiment of the expansion joint tape, the thickness of the sealing strip corresponds to the distance between the head areas of the webs, in particular the head sides of the webs facing away from the sealing strip, and the sides of the sealing strip.

The ratio of the thickness of the sealing strip, preferably at the edge, to the distance between the side walls of the cavities facing the webs with non-recessed side walls or non-recessed cavity sides of the sealing strip and at least one of the sides of the sealing strip facing these side walls can also have a value of 2.5 to 5.0, preferably 3.0 to 4.0, even more preferably 3.75. Edge thickness is also understood to mean the distance between the sides of the sealing strip in the region of the edges thereof. It is also possible for the ratio of the thickness of the sealing strip, preferably at the edge, to the distance A3 between two side walls of adjacent cavities of the sealing strip to be in a range of 2.0 to 5.0, preferably 2.5 to 4.0, more preferably 3.0.

The ratio of the thickness of the sealing strip to the distance, preferably related to the area of the edge of the sealing strip, between the side walls of the cavities of the sealing strip facing the webs and the side of the sealing strip facing these side walls is referred to as the ratio, in particular V2. The ratio of the thickness of the sealing strip, preferably at the edge, to the distance from or between two adjacent side walls of adjacent cavities of the sealing strip can be in a range of 2.0 to 5.0, preferably 3.0 or 4.0, and is also referred to as ratio V3.

To increase the sealing expansion capacity of the expansion joint tape and the joint sealing device with its expansion joint tape, in a further embodiment of the expansion joint tape, the ratio of the distance between the head regions and the edges of the sealing strip to the distance between one side of the sealing strip and the side wall of the cavity of the sealing strip facing this side is advantageous with a range of 5.0 to 7.0, preferably 5.5 to 6.5, advantageously 6.25. Preferably, the distance between the side of the head region facing the closest edge and this edge is used to determine the distance between the head region and the edge of the sealing strip.

The ratio of the distance between the head regions of the webs and the sides of the sealing strip to the width of the head region of the webs can also be in a range from 1.0 to 3.0, preferably 1.5 to 2.5, even more preferably 2.0. The width of the head region advantageously corresponds to the distance between the side facing the edge and the side of the same head region facing away from the edge.

It is also advantageous if, in a design with a retracted side wall or cavity side, the distance A4' between one side of the sealing strip and the side wall of the predetermined cavity of the sealing strip facing this side is greater than the distance A6 between one or this side of the sealing strip in the area of the web formed onto this side and the side wall of the cavity of the sealing strip facing this side. Advantageously, the distance used is that which corresponds to the distance between this side of the sealing strip in the central area of the cavity of the web formed onto the side and the side wall or cavity side of the cavity of the sealing strip facing this side. The cavity can be oval, partially circular, fully circular, angular, diamond-shaped and/or square and/or with identical opposing side walls or cavity sides, uniformly or non-uniformly designed side walls and/or with opposing side walls facing the webs that are longer or shorter than the side walls of the cavity facing the edges of the sealing strip. For the sake of simplicity, the sides or inner sides of the cavity that laterally delimit it are referred to as side walls to distinguish them from the externally arranged sides of the sealing strip.

The cavities are advantageously spaced equally apart from one another. The cavities can have the same cross-section. The cavities can also be designed as continuously extending chambers in the sealing strip or as interrupted chambers in the sealing strip separated from one another by chamber walls, e.g. aligned transversely to the direction of the cavities.

The expansion joint tape, the joint sealing tape and/or the compression tape can each be designed or manufactured in one piece and can be extruded, for example, with an elastomeric plastic-like material. One piece is also understood to mean that it can be manufactured as a whole, i.e. in one piece, e.g. extruded. The material can contain an elastic, compressible material; the expansion joint tape, the joint sealing tape, the welding lug and/or the compression tape can also be fabric-reinforced, such as textile-reinforced. The textile reinforcement can be an extensible textile fabric, which can be extruded or glued on. The fabric reinforcement can contain carbon fibers and/or glass fibers and/or steel fibers; the fabric reinforcement can be extruded onto the elastic plastic-like material and/or coextruded with it and/or glued onto it or vulcanized with it. The sealing strips, webs, etc. preferably extend continuously along or parallel to the central longitudinal axis of the sealing strip before installation, which runs in the form of a strand or band. In a special embodiment, the elastic plastic-like material of the expansion joint tape, the joint sealing tape, the welding lug and/or the compression band advantageously contain plastics which swell in the presence of water, such as TPE.

The plastic-like, preferably elastomeric, material can contain thermoplastic elastomers such as TPE; these can be polymers or thermoplastic rubbers that have a combination of the performance properties of elastomers and the processing properties of thermoplastics. This can be achieved if, for example, the macromolecules of the corresponding plastics simultaneously contain soft and elastic segments with high extensibility and a low glass transition temperature (T _g ) and hard, crystallizable segments with low extensibility, high T _g and a tendency to form associations such as physical crosslinking. The soft and hard segments are preferably incompatible with one another and exist as individual phases. Thermoplastic elastomers are also suitable if they have thermolabile, reversibly cleavable crosslinking sites, i.e. of a physical but also chemical nature. Conventional thermoplastic elastomers such as styrene-type thermoplastic elastomers are suitable. These can have butadiene or isoprene or ethylene butylene as soft polymer segments and styrene compounds such as SBS, SIS or SEBS as hard polymer segments. For example, classified into TPE classes, thermoplastic elastomers can also be used, such as those of the styrene type, which have soft polymer segments with cross-linked EPDM or cross-linked NR, or ethylene vinyl acetate or cross-linked NBR and as hard polymer segments those with propylene or those that include vinylidene chloride. These are known to those skilled in the art as EPDM/PP or NR/PP or EVA/PVDC or NBR/PP. Conventional thermoplastic elastomers are suitable, such as the thermoplastic elastomers of the polyurethane type, also soft polymer segments with ester glycols and hard polymer segments with isocyanate chain extenders or which have H bonds. Also suitable as thermoplastic elastomers are those of the polyetherester type, which have alkylene glycol as soft polymer segments and alkylene terephthalate as hard polymer segments. Also suitable as thermoplastic elastomers are those of the polyetheramide type, which have etherdiols as soft polymer segments and amides as hard polymer segments.

The thermoplastic elastomers can swell in the presence of liquids such as water.

In addition, the elastic plastic-like material can also contain components of water-absorbing compounds that swell as a result, for example cross-linked polymers such as polyacrylamide, polyvinylpyrrolidone, amylopectin, etc. As a copolymer with acrylic acid, such as propenoic acid, and acrylamide in the presence of a core cross-linker, such polymer molecules can be cross-linked with one another by chemical bridge bonds, whereby these bridges may be water-insoluble, but water molecules can attach to their polar groups. Due to the use of polar polymer compounds in the thermoplastic elastomers, the swelling of the thermoplastic elastomers is visibly supported.

The channels, for example, in the head areas of the webs can accommodate expansion bands running lengthways in them. Suitable materials for the expansion bands are conventional materials that swell in the presence of liquids, such as plastics that swell in water or rot-free or low-rotting natural materials that swell in water, other swellable coatings; materials that are rot-proof, age-resistant, resistant to UV rays, ozone, atmospheric oxygen, bitumen-proof, oil-proof, heat-resistant, petrol-resistant and/or waterproof, for example organic natural materials, organic modified natural materials, organic fully synthetic and/or inorganic swelling or thickening agents are particularly suitable.

Swelling agents also include conventional thickeners, which are preferably organic high-molecular substances that can effectively absorb water and moisture and swell in the process. The swelling visibly supports the sealing. The swelling tapes can be soaked with such swelling agents. Natural and/or synthetic fibers can also be used which can absorb water and moisture due to their hydrophilic surface. Swelling tapes can also be used which are swollen in such a way that they can attract water and moisture and swell. Swelling agents that can be used are natural organic, organically modified swelling agents such as carboxymethylcellulose, cellulose ethers, hydroxyethylcellulose, hydroxypropylcellulose and/or their derivatives, organic fully synthetic swelling agents, e.g. polyacrylic or polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides and/or their derivatives; inorganic thickeners are also suitable, e.g. polysilicic acids, clay minerals such as zeolites, silicic acids and/or their derivatives.

The sealing strip advantageously runs along the central longitudinal axis; the sealing strip can run as a flat, square cross-section, or elongated square, oval band-shaped strip, preferably with projections that are triangular in cross-section and run along the central longitudinal axis as sealing lips; apart from the cavities, the webs and channels can also extend parallel to the central longitudinal axis of the sealing strip. The projections, their shape in cross-section, the extent of the spacing from the sides of the sealing strip, from the web sides, head areas and their sides are not taken into account when determining the distances and ratios. In particular embodiments according to the invention, the projections can nevertheless be taken into account.

The webs formed on the opposite sides are advantageously arranged opposite one another and/or equally spaced from one another. The webs with recessed head areas are advantageously formed opposite one another on the sides of the sealing strip.

In a preferred embodiment of the expansion joint tape and the joint sealing device with its expansion joint tape, the cavities have side walls in cross-section that are drawn in towards the webs, so that the distance between one side of the sealing strip and the side facing this or one side, which relates to or faces the edge of the sealing strip, is Side wall of the cavity of the sealing strip is greater than the distance between one side of the sealing strip in the central region of the cavity of the web formed on this side and the side wall of the cavity of the sealing strip facing this side. As a result of this design of the cavity, the cavity or its side walls or cavity side can be drawn in in the direction of the one or both of the webs adjacent to it in a part-circular cross-section on one side or two sides and/or towards the edges on one or two sides; the thickness of the side wall of the sealing strip delimiting the cavity can thus decrease or taper in the direction of the web, so that the web can preferably follow the relative movements of the components in which the web is anchored without breaking away from the sealing strip.

The hollow chambers in the sealing strip preferably have different cross-sections; for example, in a sealing strip, hollow chambers with a square shape can alternate with hollow chambers with an elongated, angular shape, so that, for example, the hollow chamber with a square shape is located in the area of the central longitudinal axis of the sealing strip. A sealing strip can also contain hollow chambers that are only square or only elongated, angular.

Due to the properties brought about by the above-mentioned designs of the expansion joint tape and the joint sealing device with its expansion joint tape, the expansion joint tape is also suitable for use as an internal sealing device in a joint, whereby the expansion joint tape can be aligned in particular along the joint. Internal expansion joint tape also means that the expansion joint tape is arranged in the joint at a predetermined distance from the outside of the external walls.

In one embodiment of the expansion joint strip, the ratio (as A7/B2) of the distance between two adjacent webs to the width of the Head region 1.0 to 5.0, preferably 2.0 to 4.0, even more preferably 1.5., 2.0 or 3.0 or 4.0; the ratio (such as A7/A2 or A7/D) of the distance between two adjacent webs to the distance A2 or to the thickness can be 1.0 to 5.0, preferably 1.0 to 4.0, even more preferably 1.5 to 3.0 or 1.5, or 2.0 or 3.0 or 4.0. The ratio (A7/A5) of the distance A7 between two adjacent webs 5 to the distance A5 can be, for example, 0.9 to 5.0 or 1.0 to 5.0, preferably 2.0 to 4.0, even more preferably 0.9 or 1.5 or 1.64 or 2.0 or 3.0 or 4.0.

In another embodiment of the expansion joint tape, the ratio of the one-sided circulation path to the width of the sealing strip or the expansion joint tape is 2.0 to 3.5, preferably 2.5 to 3.0, even more preferably 2.63 or 2.65 or 2.98.

In an additional embodiment of the expansion joint tape, the ratio (U/D) of the one-sided circulation path or the two-sided circulation path to the thickness of the sealing strip is 4.0 to 8.0, preferably 6.0 to 8.0, more preferably 6.84 or 7.17 or 7.84 or 7.87.

In an additional embodiment of the expansion joint tape, the ratio (U/D +A2) of the one-sided circulation path or the two-sided circulation path to the sum of the thickness of the sealing strip and the distance A2 is 3.0 to 5.0, preferably 3.42 or 3.59 or 3.92 or 3.94.

The invention can also relate to a preferably internal expansion joint tape for the permanent, reliable sealing of joints, such as expansion joints between or in structures, buildings, tunnel structures, etc. and/or parts thereof with an elastic, preferably plastic-like and/or rubber-like, material, with a sealing strip, which is also characterized in that

• on the sides of the sealing strip, preferably at least three webs running along the central longitudinal axis, are formed, in particular which can be used as anchors for anchoring in buildings or parts thereof and for sealing,
• the head regions of the, preferably central, webs facing away from the sealing strip, preferably mushroom- or T-shaped, are drawn in to form channels of part-circular cross-section running along the central longitudinal axis,
• the webs are formed on at least one side of the sealing strip,
• on the opposite sides of the sealing strip and on the sides of the webs, triangular cross-section projections running along the central longitudinal axis are formed, which can be used as sealing lips for anchoring in buildings or parts thereof and for sealing. This expansion joint tape differs from the expansion joint tape listed above and below in that the sealing strip is not formed with cavities; nevertheless, the designs mentioned above and below, with the exception of the cavities, can be special embodiments of this expansion joint tape.

In this expansion joint tape, the ratio of one-sided or two-sided circulation path or distance to the thickness of the sealing strip can be 100 to 150.0, preferably 120 or 127.0, the ratio of the distance A7 to the distance A2 can be 1 to 3.0, preferably 2.34, the ratio of the width B1 to the distance A5 can be 15 to 20.0, preferably 16.0 and/or the ratio of the distance A7 to the distance A5 can be 4 to 6.0, preferably 4.67 or 4.94.

By installing the webs of the expansion joint tape and the joint sealing device with its expansion joint tape in structural parts as a result of concrete casting, there is a sufficient fixed coupling or embedding of the expansion joint tape with its webs in the concrete, so that the expansion joint tape and the joint sealing device with its expansion joint tape not only compensate for movements that occur simultaneously, for example strains and compressions or strains and expansions, while sealing the joint between building parts, between buildings and/or in them, but also help to avoid the tearing observed in the state of the art due to the limited expansion capacity of conventional joint tapes, which is traditionally not limited in terms of position. The webs and the exceptional ratios serve as additional tear-out and sealing protection in order to support the sufficient location or retention of the webs in the concrete and thus also of the expansion joint tape and the joint sealing device with its expansion joint tape in the joint, to support the expansion of the webs and the sides or walls of the sealing strip adjacent to the webs as a result of strong relative movements of the buildings to one another, and to seal the space between the sealing strip and the inner joint walls of the joints of the buildings to prevent water from entering.

The term expansion joint tape can also be understood as a construction joint tape. In the sense of the invention, the term expansion joint tape is also understood as a joint tape whose webs and/or projections are firmly embedded as sealing lips in structural parts as a result of material casting, such as concrete casting; the term construction joint tape is also understood as a joint tape which, in contrast to the expansion joint tape, at least largely contains no elastic material. The construction joint tape is used when, for example, components cannot be manufactured in one concreting step. The construction joint tape can usually run vertically in the component and should be installed half in the first and half in the second concreting step.

A process is used to seal a joint between concrete walls by placing a protective shoe, preferably made of plastic, metal and/or wood, against one side of the expansion joint strip to accommodate the webs in pre-formed web spaces; the inner walls of the web spaces can be modelled on the outer contour of the webs. Against the edges of the expansion joint strip, battens or strips, which can contain a plastic, metal and/or wood, are placed along the centre longitudinal axis of the

Expansion joint tape is applied to protect the edges of the expansion joint tape from damage. The panelled space containing the other side of the expansion joint tape with the webs and steel reinforcement is then filled with concrete. After the concrete has hardened, the protective shoe is removed and the panelled space containing the one side of the expansion joint tape with the webs and steel reinforcement is filled with concrete; after the concrete has hardened, the battens or strips are removed, e.g. conventional sealing strips are then applied against the edges of the expansion joint tape and/or the compression band arrangement is inserted between the joint sides of the external walls of a building that border the joint.

• Dehnung (Auseinanderdriften),
• Stauchung (Zueinanderbewegung)
  und /oder
• Zerrungen (entgegengesetzte Bewegungen entlang der Lotrechten).

The special properties caused by the above-mentioned designs of the expansion joint tape and the joint sealing device with its expansion joint tape lead to the desired permanent joint sealing even in spite of the relative movements observed in the building components, such as

• Stretching (drifting apart),
• Compression (movement towards each other)
  and or
• Strains (opposite movements along the vertical).

The compression band arrangement, which can be comprised of the expansion joint band and the joint sealing device with its expansion joint band, and the joint sealing device can apply a force to the elastic compression band as a result of screwing, so that it deforms as a result of the force application and adapts its shape to the surface configurations of the front sides in a sealing manner. In one embodiment of the compression band arrangement for the permanent, reliable sealing of joints, such as, preferably edge-adjacent, joint areas between or in buildings, preferably Tunnel structures, and/or parts thereof, the channels accommodate swelling bands to increase the seal. The compression band can be compressed. As a result of the force applied when the screw is screwed into the inner jaw to move from the starting position or open position to the end position or sealing position, it clings to the sides of the joint to form a seal. By unscrewing the screw from the internal thread of the inner jaw, the compression band is relieved as a result of the transition from the end position to the starting position and can be easily replaced if necessary. Shortening the distance between the inner jaw and the outer jaw along a straight line enables the desired, even force to be applied to the compression band in the correct position, so that the compression band is evenly applied to both sides of the joint and the gap bridging both sides of the joint is reliably sealed.

To shorten the distance between the inner jaw and the outer jaw, the outer jaw can be placed on both sides against the joint walls that border the edge joint area; it is also possible for the outer jaw to be introduced into the edge joint area like the inner jaw, so that as a result of the shortening of the distance between the inner jaw and the outer jaw, the outer jaw is increasingly moved into the joint area in the direction of the inner jaw.

In cross-section, at least one area of the compression band facing the inner jaw or the outer jaw is U-shaped for positively receiving or attaching the inner or outer jaw. In the sense of the invention, compression band is also understood to mean a sealing band which is elastic, deformable and/or compressible, for example as a result of the application of force. Likewise, both areas of the compression band facing the outer jaw and the inner jaw can be U-shaped. The inner jaw and/or the outer jaw can have tapered elevations in their cross-section facing the compression or sealing band, which engage in the compression band in a force-fitting, frictional and/or positive-fitting manner. In one embodiment of the compression band arrangement, the inner jaw, the outer jaw and/or the compression band run along the central longitudinal axis Z of the inner jaw and outer jaw. The compression band arrangement is particularly suitable for sealing a joint to the outside and/or to the inside. The compression band arrangement is particularly suitable for sealing installation in a joint transversely and/or lengthwise to the same.

In the design of the expansion joint tape of the joint sealing device with its expansion joint tape h with, for example, three pairs of webs on both sides of the sealing strip, a largely temporal sequence of gradual movements can be observed in the event of loads, e.g. in the event of expansion (drifting apart of the adjacent structures) or strains (opposite movements of the structures along the vertical), whereby

• first the sealing strip is stretched or compressed under load,
• under heavy loads the webs are stretched, but the webs with their head areas remain hooked into the concrete in a positionally accurate and watertight manner,
• the side walls, to which the webs are formed, are subsequently stretched but do not tear due to their thickness tapering towards the webs,
• but under greater loads the cavities in the sealing strip are deformed, but the webs remain hooked into the concrete to seal,
• so that the expansion joint tape is characterised by a permanent anchoring in the joints of the structures and thus a sealing of the space or gap, also called an internal joint, between the internal joints of the structures that accommodate the webs and the webs of the expansion joint tape

• auch bei dem schwachen oder starken,
• kurzzeitigen oder langandauernden sich einstellenden Auseinanderdriften der Bauwerke,
• wie auch bei häufig sich einstellenden Hin- und Rückbewegungen derselben,
• ohne dass Risse oder Spalte in dem Dehnungsfugenband im Gegensatz zum Stand der Technik aufzutreten vermögen.

The sequence of gradual expansions of the expansion joint tape and the joint sealing device with its expansion joint tape advantageously enables the sealing of the gap

• even with the weak or strong,
• short-term or long-term drifting apart of the structures,
• as well as in the case of frequent back and forth movements of the same,
• without cracks or gaps occurring in the expansion joint tape, in contrast to the state of the art.

The expansion joint tape and the joint sealing device with its expansion joint tape also seals joints between the structures, regardless of the extent of the thermal and/or seismic movements, against water and sound ingress and heat, even when high water pressure occurs inside the joint as a result of the action of the water pressure.

In addition, the advantage of the expansion joint tape and the joint sealing device with its expansion joint tape is that the higher the water pressure to which the expansion joint tape is subjected, the more effectively the expansion joint tape seals.

The mushroom or T-shaped geometry of the webs of the expansion joint tape and the joint sealing device with its expansion joint tape also permanently increases the sealing effect with increasing loads from pressing water and/or increasing deformation; larger movements of the structures and their parts in combination with pressurized water are also possible and do not lead to any leakage of the expansion joint tape according to the invention bridging or delimiting the gap or joint between the structures or parts.

It turns out that the expansion joint tape and the joint sealing device with its expansion joint tape due to the skillful interaction and interaction

• the special wedge-shaped design of the sealing strip and its advantageous dimensions,
• the formation of the bridges in their head areas,
• the cavities in the sealing strip

• set and permanently
• not only the gap or joint between buildings,
• but can also seal the space between the webs and the internal joints of the structures that accommodate the webs.

Bridging joints in buildings also means spanning or overlapping joints between adjacent building parts, such as floor surfaces, between adjacent wall surfaces and/or between floor surfaces and a wall surface or between floors, between walls or between floor and wall or between other building parts, so that the adjacent building parts can be connected to one another, for example to close or limit the joints.

The expansion joint tape and the joint sealing device with its expansion joint tape can be extruded with webs, sealing strips and/or sealing lips, etc. or these parts, such as webs, can be co-extruded onto the sealing strip. The expansion joint tape can also be extruded with a plastic-like material, i.e. in a material-locking manner, or co-extruded from various plastic-like materials, whereby certain parts, such as projections that can be used as sealing lips, can also be co-extruded or extruded onto the sealing strip. Thermoplastic elastomers, elastomers or other plastic-like materials and/or rubber-like materials can be suitable as plastics, also called plastic-like materials. These can be made of PVC, PVC/NBR (nitrile/butadiene plastic-like materials), TE, TPE, PE, PP, SPR, EPDM, elastomer mixtures or other elastomers that can be deformable or re-formable.

It is also understood as expansion joint tapes, which can be installed inside and/or outside, or construction joint tapes or joint closure tapes, e.g. for flush closing of a joint, which can be installed inside or outside. Expansion joint tape is also understood to mean bridging a gap between two buildings or parts of a building, as well as sealing a building joint between an existing old concrete structure and a new concrete structure that is to be attached to it and is to be freshly poured. When installing or installing expansion joint tapes, the formwork can be slit at the point where the conventional joint tape is to be installed so that the middle part of the expansion joint tape can fit into this slot, the side part of the expansion joint tape can be bolted to the formwork or reinforcement. After concreting and removing the formwork, a joint filler plate can be applied, such as glued, to both sides of the middle part. Construction joint tapes are traditionally particularly suitable when components are not manufactured in one concreting section; the construction joint tapes can often run vertically in the component and can be installed approximately halfway inside or half outside in the first or second concreting section.

Joints also include standing joints, movement joints, construction joints and dummy joints. Standing joints are joints in which no or only minimal movement can occur. Movement joints can be pre-planned interruptions in certain sections of components, the width of which can expand as a result of heating from solar radiation and become narrower when cold sets in. Movement joints also occur when structures settle due to vibrations. Construction joints can occur when an interruption is necessary during the construction of a building, when changing building materials, e.g. prefabricated columns and masonry.

The expansion joint tape can be extruded in one piece from a plastic-like material. The term "one piece" also means that it can be manufactured as a single unit, e.g. extruded.

The expansion joint tape and the joint sealing device with its expansion joint tape and/or the joint sealing tape and/or the compression tape, the inner jaw and/or the outer jaw can contain an elastic, compressible material; the expansion joint tape and/or the joint sealing tape and/or the compression tape, the inner jaw and/or the outer jaw can also be fabric-reinforced, such as textile-reinforced. The textile reinforcement of the expansion joint tape and/or joint sealing tape and/or compression tape, inner jaw and/or outer jaw according to the invention can be an extensible textile fabric, which can be extruded or glued on. The fabric reinforcement can contain carbon fibers and/or glass fibers and/or steel fibers; the fabric reinforcement can be extruded onto the elastic plastic-like material and/or coextruded with it and/or glued onto it or vulcanized with it. The strips, the webs, the side bands, the channels, the connecting channel, the central piece, the end parts, the intermediate parts, the channels and/or the grooves extend continuously along or parallel to the central longitudinal axis LA of the longitudinal cavity before installation, which runs along the strand- or band-shaped expansion joint tape according to the invention.

The expansion joint tape and the joint sealing device with its expansion joint tape enable sufficient sealing of the joints between structures, between two tunnel segments, regardless of their relative movements to each other.

• bei Dehnungen, wie Auseinanderdriften der Bauwerke, wie das von zwei Tunnelsegmenten, voneinander,
• bei Stauchungen, wie Zueinanderbewegungen der Bauwerke, wie das von zwei Tunnelsegmenten, zueinander
  und
• bei Zerrungen, bei Bewegungen der Bauwerke, wie das von zwei Tunnelsegmenten, zueinander parallel zu der Lotrechten, da
• die Beobachtung zeigt, dass bei Zugbeanspruchung die Stege und die den Stegen benachbarten Seitenwände des Dehnungsfugenbandes als Dehnungszone gedehnt und im Querschnitt schmaler werden, hingegen die Abdichtung der Fuge gewahrt verbleibt.

The sealing of the joint is permanent both

• in the case of expansions, such as drifting apart of the structures, such as that of two tunnel segments, from each other,
• in the case of compression, such as movements of the structures towards each other, such as that of two tunnel segments,
  and
• in the case of strains, in the case of movements of the structures, such as that of two tunnel segments, parallel to each other to the vertical, since
• The observation shows that under tensile stress, the webs and the side walls of the expansion joint tape adjacent to the webs are stretched as an expansion zone and become narrower in cross-section, whereas the sealing of the joint remains intact.

The sealing effect of the webs and the sides of the sealing strip against the sides or inner walls of the joint effectively prevents the water circulation that can be observed with conventional joint tapes.

In the event of particularly strong tensile stress on the expansion joint tape and the joint sealing device with its expansion joint tape, for example in the event of seismically induced expansion and/or strain, the expansion zone in the area of the sealing strip adjacent to the webs may increase in size, but the intimate sealing contact between the webs and the joint sides remains, as with two tunnel segments.

In addition, the sealing of the joint or gap between structures and/or their structural parts, such as between two tunnel segments, by means of the expansion joint tape not only concerns sealing against water, but also against heat and/or sound.

The expansion joint tape is also characterized by its versatile use as an expansion joint tape and construction joint tape, which can be used both internally and externally.

The expansion joint tape and the joint sealing device with its expansion joint tape enable expansion both in the area of the central section, such as the central strip and the hose, and in the area of the side bands, without the side bands changing their location or position, also called tight fit, in the concrete.

The expansion joint tape and the joint sealing device with its expansion joint tape enable expansion of the side bands, which also support the expansion of the middle section when several relative movements occur simultaneously, such as compressions with strains or expansions with strains.

Due to the special design of the middle section in the form of an H-shaped longitudinal cavity, the expansion joint tape and the joint sealing device with its expansion joint tape also enable permanent sealing of the interior of the joint against the ingress of moisture and water, even in the event of high water pressure, and leads to sufficient insulation against cold and other adverse weather conditions.

In a method for providing the compression band arrangement, an inner jaw is inserted from the outside as a pressure rail into the joint or joint area laterally delimited by the joint sides of the outer walls, then the sealing band is inserted as a compression band or sealing profile, which has expansion bands accommodated in channels on its sides facing the joint sides; a sealing band and then a Flat profile as an outer jaw against the outside. A threaded strand as a screw is passed through the holes in the flat profile and the sealing tape and screwed into the holes in the inner jaw with internal thread to apply force to the compression tape so that it seals against the joint sides. Alternatively or additionally, a hexagon nut can be screwed on to hold the end of the screw facing away from the compression tape. The end of the screw facing away from the compression tape is then passed through a flat profile to the outside to additionally cover the joints and secured in the end position or sealing position using a cap nut.

The joint sealing device comprises, for example, the expansion joint tape for the permanent, reliable sealing of joints, such as expansion joints between or in structures, buildings, tunnel structures, etc. and/or parts thereof with an elastic, preferably plastic-like and/or rubber-like, material, with a sealing strip and the compression band arrangement, since these can work together to seal a joint on the inside and to seal the joint to the outside and/or to the inside.

It also turns out that both the expansion joint tape and the use of the compression tape arrangement provide an unexpectedly long-lasting joint seal. The sealing inside the joint in or between structures or in or between parts thereof by the expansion joint tape, the sealing of the joint sides bordering the joint that are close to the outside of the structure or parts thereof by the compression tape arrangement can also be achieved in combination by using the combination of expansion joint tape and compression tape arrangement without limiting their technical successes, surprising properties or the advantages that arise as a result of the technical successes.

The method for reliably and permanently sealing a joint between concrete walls using a protective shoe and formwork and the method for producing the compression band arrangement can also work together skillfully.

In one embodiment of the method for producing the joint sealing device with the two adjacent tunnel segments 08 and the use thereof, the sealing film is placed against the outside of a rock of a drilled tunnel tube, which in a special embodiment is already glued or welded to the expansion joint tape and its other edge area on the side of the sealing film facing away from the rock. Likewise, in another embodiment, the sealing film can be made in one piece with the expansion joint tape. By providing a conventional formwork for producing a tunnel segment, the space between the rock and the formwork is filled with a concrete-like mass to produce the wall of a tunnel segment, so that the concrete-like mass is placed flat against the side of the sealing strip, against the webs and against the inside of the welding lug, which is opposite the outside facing the rock or outer side of the welding lug. After the mass, preferably a concrete-like mass, has hardened, a second formwork can be provided using a conventional procedure known to the person skilled in the art to provide a second tunnel segment and its wall adjacent to it, so that as a result of the filling of the gap between the rock and the second formwork, the preferably concrete-like mass is also applied flatly to the other side of the sealing strip of the expansion joint tape and against that of the webs. In addition, before filling the gap of the second formwork, the area of the joint that is not to be filled with the expansion joint tape can be attached with panels made of plastic-like materials, such as polystyrene or the like, against the front side of the already made wall of the first tunnel segment, and can be received by the joint sealing tape, which is inserted in the area of the joint on the inside opposite the pressurized water side. The joint sealing device can be the expansion joint tape, which is attached or can be attached against the front sides of the two adjacent Walls of the tunnel segments, and the joint closure strip, which is also attached or can be attached flat against the front sides of the two walls of the adjacent tunnel segments, wherein the outer side of its section, which is arranged between the two legs, is aligned and/or flush with the inner sides of the walls of the tunnel segments.

The ratio V1 of the circulation path U to the thickness D of the sealing strip can be in a range from 10.0 to 30.0, preferably 21.67, 18.64 or 23.34; the thickness D of the sealing strip and the distance between the head sides of the head regions of the webs and the sides of the sealing strip can match each other. In cross-section, the width of the web neck to the width of the web foot can be reduced by 10 to 25%, preferably 15 to 20%, even more preferably 17.55%; on the other hand, it is advantageous if the ratio V2 of the thickness D of the sealing strip, preferably at the edge, to the distance, preferably related to the region of the edge of the sealing strip, between the side walls of the cavities of the sealing strip facing the webs and the side of the sealing strip facing these side walls is in a range from 2.5 to 5.0, preferably 3.75 or 4.0. It is also preferable if the ratio V3 of the, preferably edge-located, thickness D of the sealing strip to the distance between two side walls of adjacent cavities of the sealing strip is in a range from 2.0 to 5.0, preferably 3.00, the ratio V4 of the distance between the side of the head region facing the edge and the edge of the sealing strip to the distance between one side of the sealing strip and the side wall of the cavity of the sealing strip facing this side is in a range from 3.0 to 7.5, preferably 5.0 to 7.0, more preferably 3.44 or 6.25. Preferably, the ratio V5 of the distance between the head sides 6c of the head regions of the webs and the sides of the sealing strip to the width of the head region of the webs is in a range from 1.5 to 3.0, preferably 2.0. In addition, the distance between the side of the sealing strip and the side wall of the cavity of the sealing strip facing and/or facing away from one edge of the sealing strip can be greater than the distance between the side of the sealing strip in the central region of the web formed on the side of the sealing strip and the side wall of the cavity of the sealing strip facing this side and the projections may be triangular, mushroom-shaped and/or T-shaped in cross-section.

The expansion joint tape 1 contains a conventional plastic-like material which is reshapable and comprises a sealing strip 2, wherein the sealing strip 2 has cavities 3 extending continuously within the sealing strip 2 along its central longitudinal axis X; on the sides 4 of the sealing strip 2, three webs 5 running along the central longitudinal axis X are formed on both sides, which serve as positionally secure or fixed anchors in the concrete. The cavities 3 run along the central longitudinal axis X. The webs 5 are aligned perpendicular to the central longitudinal axis X before installation. In cross-section, in one embodiment, the web 5 tapers from its web neck 5c, which faces away from the sealing strip 2, towards its web foot 5b, which faces the sealing strip 2; Thus, in particular embodiments, the width of the web neck 5c is reduced in cross-section to the width of the web foot 5b by 16% or 17.55% or 18%. The web 5 comprises the web neck 5c facing the head region 6 of the web, which merges into the web arm 11b, with the web arm 11b merging into the web foot 5b facing the sealing strip 2. The width of the web neck 5c is also understood to mean the distance of the web sides 11 of the web 4 to or from each other that face the head region 6; the width of the web foot 5b is also understood to mean the distance of the web sides 11 to or from each other that face away from the head region 6 of the web 5.

The T-shaped or mushroom-shaped head regions 6 of the middle webs 5 facing away from the sealing strip 2 are drawn in to form channels 7 running along the central longitudinal axis X in one embodiment with a three-quarter circular cross-section. The webs 5 are formed in the central regions 80 of the cavities 3 of the sealing strip 2 on the sides 4 of the sealing strip 2. Under the central region 80 of a cavity 3 also understood to be the area which is equally spaced from the two opposite cavity sides 28. In one embodiment, the head regions 6 of the two outer webs 5d, also called edge webs, are oval in cross section and have projections 10 which run along the central longitudinal axis X. In another embodiment, the head regions 6 of the central webs 5, which are arranged between the edge webs 5d, are fully circular in cross section and their head sides 6c are drawn in to form channels 7, and the head regions 6 are at least partially covered with projections 10 which run along the central longitudinal axis X.

Thus, in one embodiment, the walls 82 facing the webs 5 taper in cross-section to form a cavity with a partial circular shape on one side, i.e., they are drawn in towards the webs 5; the walls 82 delimit the cavity 3 in the direction of the webs 5, i.e. on the web side, from their two end regions 81, which are arranged between the webs 5 or face the edges 27, in the direction of their central regions 80, wherein the webs 5 are formed in central regions 80 on one or the two opposite sides 4 of the sealing strip 2.

The design of this wall 82 is of course also implemented in a further embodiment for a sealing strip 2 with several cavities. For the sake of simplicity, the sides or inner sides of the cavity 3, which laterally delimit the interior of the cavity 3, can also be referred to as side walls 9 to distinguish them from the externally arranged sides 4 of the sealing strip 2.

In another embodiment with a cavity 3 that is drawn in on two sides in a partially circular shape, the two opposite walls 82 that delimit the cavity 3 in the direction of the two opposite webs 5, i.e. on the web side, taper in cross-section from their end regions 81 in the direction of their central regions 80. The tapers of both the webs 5 and the walls 82 in cross-section significantly increase the resilient adaptability and elasticity of the expansion joint tape 1 in the event of structural offset. In one embodiment, the webs 5, 5d taper in cross-section from their web necks 5c facing away from the sealing strip 2 in the direction of their web feet 5b facing the sealing strip 2, and the wall 82 delimiting the cavity 3 on the web side tapers from its end regions 81 in the direction of its central region 80. The cavities 3 facing at least the edges 27 of the sealing strip 2 can also be square or elongatedly angular in cross-section.

The one-sided or two-sided circulation path U in cross-section, which is implemented by the expansion joint tape 1, extends the moisture path along which the moisture is forced to creep in order to get outwards from the inside out of the joint 19 or from the outside inwards into the joint 19, so that the sealing provided by the positional stability of the webs 5 remaining or embedded in the concrete is cooperatively supported. In another embodiment, on the opposite sides 4 of the sealing strip 2 and on the web sides 11 of the webs 5, projections 10 which are triangular or mushroom-shaped or T-shaped in cross-section and run along the central longitudinal axis X are formed as sealing lips; the edges 27 of the sealing strip do not have any projections 10 in one embodiment. The projections 10 significantly increase the moisture distance, i.e. the circulation path U, along which the moisture creeps in order to get outwards from the inside of the joint 19 or from the outside to the inside into the joint 19, so that the sealing is thereby visibly supported even more strongly by the expansion joint tape 1. The following and aforementioned disclosed conditions preferably refer to those calculated in the cross-section of the expansion joint tape, without having to be expressly marked as such.

• der Länge der Seite 4 der Dichtungsleiste 2,
• der Längen der Stegseiten 11 der an dieser Seite angeformten Stege 5,
• der Längen der Seiten 11c des Kopfbereichs 6 der Stege 5, wie der Längen der Kopfseite 6c und der beiden gegenüberliegenden Seiten 6a des Kopfbereichs 6, die den Rändern 27 zugewandt sind,
  und
• den Längen der Seiten 11a der Vorsprünge 10 errechnet. Einfach gesagt, die einseitige Umlaufstrecke umfasst den Weg von einem Rand 27 der Dichtungsleiste 2 zu dem anderen dem einen Rand 27 gegenüberliegenden Rand 27. Ebenso wird in einem anderen Ausführungsbeispiel für die Berechnung des zweiseitigen Umlaufwegs oder -strecke U die vorgehend ermittelte einseitige Umlaufstrecke verdoppelt.

In one embodiment, the one-sided orbital distance U is used, which in cross-section is the sum of

• the length of side 4 of sealing strip 2,
• the lengths of the web sides 11 of the webs 5 formed on this side,
• the lengths of the sides 11c of the head region 6 of the webs 5, such as the lengths of the head side 6c and the two opposite sides 6a of the head region 6 facing the edges 27,
  and
• the lengths of the sides 11a of the projections 10. Simply put, the one-sided circulation path comprises the path from one edge 27 of the sealing strip 2 to the other edge 27 opposite the one edge 27. Likewise, in another embodiment, for the calculation of the two-sided circulation path or path U, the previously determined one-sided circulation path is doubled.

The ratio V1 of the one- or two-sided circulation path U to the thickness D of the sealing strip 2 is 21.67 in cross-section in one embodiment. The thickness D of the sealing strip 2 corresponds to the distance A2 between the head regions 6 of the webs 5 or the head sides 6c of the head regions 6 and the side 4 of the sealing strip 2 facing towards or away from the webs in cross-section. The ratio V2 of the thickness D of the sealing strip 2 to the distance A1, related to the area of the edge 27 of the sealing strip 2, between the side walls 9 facing the webs 5 of the cavities 3 of the sealing strip 2, which are not recessed in one embodiment, and the side 4 of the sealing strip 2 facing these side walls is 3.75 in cross-section in one embodiment.

The ratio V2 of the thickness D of the sealing strip 2 to the distance A1, e.g. related to the area of the edge 27 of the sealing strip 2 or facing this area of the edge 27, between the side walls 9 of the cavities 3 of the sealing strip 2 facing the webs 5 and the side 4 of the sealing strip 2 facing these side walls 9 lies in a range of 3.75 or 4.0 in another embodiment. The ratio V3 of the edge-side thickness D of the sealing strip 2, i.e. facing the edge 27 to the distance A3 between two side walls 9 of adjacent cavities 3 is in a completely different embodiment, e.g. regardless of whether the cavity sides 9 of the cavities 3 facing the sides 4 are retracted or not retracted, the sealing strip 2 is 3.0.

The ratio V4 of the distance A5 between the head regions 6 and the edges 27 of the sealing strip 2 to the distance A1, related to the area of the web 5 of the sealing strip 2, between a side 4 of the sealing strip 2 and the side wall 9 of the cavity 3 of the sealing strip 2 facing this side 4 is 6.25. The side wall is also understood to mean the cavity side 9 that delimits the interior of the cavity 3. In one embodiment, the distance A5 refers to the distance between the sides 6a of the head regions 6 facing the edges 27 closest to the sides 6a and these edges 27 of the sealing strip. The ratio V5 of the distance A2 between the head regions 6 of the webs 5 and the sides 4 of the sealing strip 2 to the width B2 of the head region 6 of the webs 5 is 2.0. The width B2 of the head region 6 is also understood to mean the distance between the side 6a of the head region 6 facing the edge 27 and the side 6b of the head region 6 facing away from the edge 27.

The distance A4' relating to or attributable to one edge 27 of the sealing strip 2 between the side 4 of the sealing strip 2 and the side wall 9 of the cavity 3 of the sealing strip 2 facing the side 4 is greater than the distance A6 between the side 4 of the sealing strip 2, which is located in the central region 80 of the cavity and on which the web 5 is formed, and the side wall 9 of the cavity 3 of the sealing strip 2 facing this side 4.

The cavities 3 are equally spaced from each other. The cavity sides 9 facing the sides 4, also called cavity walls, are longer in cross-section than the cavity sides 28 facing the edges 27. The channels 7 accommodate strand-shaped expansion bands 7a. The sealing strip 2 extends along the central longitudinal axis X. The sealing strip 2 is flat, band-shaped. The strip or nose 123, the webs 5, the projections 10, the drawn-in sections, e.g. the side wall 9 facing a web or the cavity side 28 facing the edge, also called indentations, run parallel to the central longitudinal axis X of the sealing strip 2. The webs 5 are arranged opposite one another; however, they can also be arranged with a gap. In one embodiment, the cavities 3 have side walls 9 drawn in as indentations in the cross section in the direction of the webs 5. The swelling bands 7a contain materials that swell in the presence of liquids such as water, such as plastics.

The expansion joint tape can be formed by pressing, extrusion, injection molding, in one piece and with a material bond. The expansion joint tape can also be made from thermoelastic plastics such as elastomers, plastomers and duromers or mixtures thereof. The expansion joint tape is heat-resistant, has sufficient dimensional stability and rigidity while maintaining its elasticity.

The sealing arrangement for the permanent, reliable sealing of joints 19 between or in structures 41 and/or parts thereof with an elastic material, in particular of expansion joints 104 between, e.g., two tunnel segments 112, comprises the expansion joint tape 1, 1a, tunnel segments 108 which are spaced apart from one another by means of, e.g., a circumferential expansion joint 104, 19, which tunnel segments 108 lie opposite one another, wherein a strand-shaped expansion joint tape 1, 1a is located in the expansion joint 104, 19 for sealing the expansion joint 104 of two adjacent or bordering tunnel segments 108 against the ingress of water via the outside of the segment wall 107 as the pressurized water side 112; the expansion joint tape 1, 1a is aligned in one embodiment with its longitudinal center plane LE in the expansion joint 104, 19 transversely to the longitudinal extension L of the tunnel segments 108, wherein the longitudinal center plane LE can be equally spaced from the outer sides 116 of the edge regions 101 and 109 and can extend parallel to the central longitudinal axis X. The expansion joint tape 1, 1a is with its webs 5 embedded in a mass, in particular a concrete-like mass, so that the sides 4 of the sealing strip 2 can also lie flat against the joint sides 19a of the concrete-like mass delimiting the expansion joint 104, 19, in contrast to conventional expansion joint strips. One edge area 101 of the expansion joint strip 1, 1a is spaced from the inner side 114 of the tunnel segments 108 opposite the pressurized water side 112, also called the segment wall inner side.

In addition, in a further embodiment, the other edge region 109 of the expansion joint strip 1, 1a is adjacent to the pressurized water side 112, preferably its outer side 116 of the other edge region 109 is flush and/or aligned with the outer side 107 of the joint wall or walls 119 of the tunnel segments 108 delimiting the expansion joint 104, 19 or their outer sides facing the pressurized water side 112. The expansion joint 104, 19 is permanently sealed in an expansion joint region 19 opposite the pressurized water side 112 with a joint sealing strip and/or a compression strip arrangement.

The one-piece joint sealing tape 111, which extends in the form of a strand, contains a plastic-like elastic material which is preferably capable of swelling in the presence of water, and is U-shaped in cross-section, with its two legs being aligned perpendicularly to its section in cross-section and connected to its ends. On their outer sides 4, webs 5 running along its central longitudinal axis X are formed; the webs 5 formed perpendicularly to the webs 5 are also embedded in a mass, in particular a concrete-like mass, after installation, so that their outer sides 4 can also lie flat against the joint side 19a of the concrete-like mass which delimits the expansion joint.

The sealing arrangement, especially with the preferred design of the other edge area 109 of the sealing strip of the expansion joint tape and its arrangement near the pressure water side 112, ensures in the expansion joint 104 of the two adjacent or opposite Tunnel segments 108 and their front sides 117 permanently and unexpectedly for the expert the sealing between the expansion joint tape 1, 1a on the one hand and the front side 117 or the pressed concrete-like mass 121 on the other hand, so that a reliable liquid and moisture seal is established between the two laid tunnel segments 108 in the presence of the relative movements to be observed, such as expansions (drifting apart), compressions (movements towards each other) and / or strains (opposite movements along the vertical or bevels).

Unter Längserstreckung L wird auch verstanden, dass die Längserstreckung L längs auch parallel zu der Mitte-Längsachse der Tunnelsegmente 108 verläuft. Unter Mitte-Längsachse eines Tunnelsegments kann auch die Mitte-Längsachse Za einer Wand desselben verstanden werden, wobei die Mitte-Längsachse Za einer Wand 119 des Tunnelsegmentes 108 von der Außenseite 107 und der Innenseite 114 der Wand 119 desselben (Fig. 19) gleich beabstandet ist.

The centre transverse axis A is understood to be the axis with matching distances to the sides 4 of the sealing strip 2, on which the webs 5 are formed, and which advantageously runs parallel to these sides 4 and can extend from the one edge region 101 to the other edge region 109, which can also have the strip 123.

• whose distances to the outer sides 116 or outer sides 116 of the edge regions 101, 109 of the sealing strip 2 are identical to each other ( Fig. 19 ).

The inner jaw 31 has a hole with an internal thread to accommodate a screw; when moving from the starting position to the end position, the screw is screwed into the internal thread of the inner jaw 31 while applying force to the compression band as a sealing band 33 for sealing the same against the joint sides 19a delimiting the joint 19. Since the compression band 33 is elastic, it forms a seal in the event of displacement of the outer walls 41a delimiting the joint. Edge joints also include joints that border on the outer sides 71 of outer walls 41a or are arranged in the area of outer walls 41a.

The sides 36 of the compression band 33 adjacent to the joint sides 19a are drawn in to form channels 7 that are at least partially circular in cross section.

In one embodiment, the permanently highly resilient joint sealing device comprises, in addition to the expansion joint tape as a joint sealing device, a compression band arrangement for permanently, reliably sealing marginal joint areas 19 or bridging the joint gap 19b` between or in structures 41, preferably tunnel structures, and/or parts thereof, which comprises an inner jaw 31 which can be inserted into the joint area 19 and has a perforation with an internal thread and an outer jaw 32 which can preferably be placed against the outer sides 71 of the joint walls 41a delimiting the marginal joint area 19 and has a the inner jaw 31 has an opening for receiving a screw (35) that can be screwed in, a compression band 33 containing compressible elastic material being arranged between the inner jaw 31 and the outer jaw 32; advantageously in an end position, the screw 35 is screwed into the internal thread of the hole in the inner jaw 31 while applying force to the compression band 33 for sealingly applying the same against the joint sides 19a delimiting the joint 19, the sides 36 of the compression band 33 adjacent to the joint sides 19a are drawn in to seal the gap 19b` bridging the joint to form channels 7 that are at least partially circular in cross section and that receive the expansion bands 7a, 33a.

• die Seiten 4 auch Längsseiten genannt, aufgrund deren größeren Ausdehnung als die Querseiten oder Außenseiten 116 von dem einen oder anderen Randbereich des Dehnungsfugenbandes,
• die Stege 5 parallel zu der Längserstreckung L der Tunnelsegmente 108 ausgerichtet sind,
• die Dichtungsleiste 2 mit ihrer Leiste und dem anderen Randbereich 109 im Bereich der dem Druckwasser (Pfeile P5 in Fig. 19) zugewandten Außenseite der Segmentwand angeordnet ist und mit ihrem einen Randbereich 101, der dem anderen Randbereich 109 gegenüber liegt, in Richtung zu der Innenseite 114 bzw. zu dem Innenraum der Tunnelsegmente angeordnet ist,
• die Mitte-Längsachse X und die Mitte-Querachse A quer zu der Längserstreckung L der Tunnelsegmente angeordnet sind.

The expansion joint strip 1 is arranged, for example, in the joint which is delimited by the two end faces 117 of the adjacent walls of the tunnel segments, in such a way that, for example,

• the sides 4 also called longitudinal sides, due to their larger size than the transverse sides or outer sides 116 of one or the other edge area of the expansion joint tape,
• the webs 5 are aligned parallel to the longitudinal extension L of the tunnel segments 108,
• the sealing strip 2 with its strip and the other edge area 109 in the area of the pressurized water (arrows P5 in Fig. 19 ) facing the outside of the segment wall and with its one edge region 101, which is opposite the other edge region 109, is arranged in the direction of the inner side 114 or the interior of the tunnel segments,
• the central longitudinal axis X and the central transverse axis A are arranged transversely to the longitudinal extension L of the tunnel segments.

As a result, the longitudinal center plane LE of the sealing strip 2, which runs along the center longitudinal axis X and extends transversely to the center transverse axis A and is aligned perpendicular to the sides 4 of the sealing strip, will also be aligned along the longitudinal extension L of the tunnel segments 108.

Simply put, the arrangement of the expansion joint tape 1 of the joint sealing device now transverse to the longitudinal extension L and no longer parallel to it, as prescribed in the prior art, enables permanent sealing of the joint 19 even in the event of an accident in which the gap bridging the joint 19 can have different gap widths.

It turns out that the formation of the channels 7 in the head regions 6 of the webs 5 is particularly advantageous. Overstressing in the form of excessive tensile stress also leads to mechanical pressure on the expansion band 7a located in the channel 7 of the head region 6 of the web 5. This causes the expansion band to be partially pushed outwards on the open side of the channel 7, so that water circulation or water creeping around the head region 6 of the web 5 is suppressed. If no water enters or moisture enters, the expansion band remains in the channel 7 of the head region 6 of the web, but they can swell or even partially leave the channels when water enters.

As in Fig.2 shown, by moving the tunnel segments, a force acting on the web 5 in the direction (arrow P1) can act on the head area 6 of the web 5 in such a way that the tensile stress caused by this leads to a deformation (arrow P2) in the web arm 11b or to the expansion of the same and in the head area (arrow P3); even if in this case no water should enter the head area 6 of the web 5, the pressure (arrow P1) can under certain circumstances cause the swelling band 7a (arrow P4) to emerge and create an additional seal between the head area 6 and the area adjacent to the head area 6. adjacent concrete or the concrete-like mass. Even in the event of water entering the head area 6, the swelling of the expansion band 7a particularly advantageously effectively prevents the water from circulating or wandering around the head area 6 due to the swelling of the expansion band 7a and additionally due to the leakage of the expansion band (arrow P4).

The joint sealing device can comprise not only the expansion joint tape 1 and/or the joint sealing device, but also the two adjacent tunnel segments 108. In this embodiment, the expansion joint tape 1 is aligned with its sides 4 parallel to the end faces 117 of the wall 41 of the tunnel segments 108 in the joint, so that the webs 5 are along the longitudinal extension L of the tunnel segments 108, the center longitudinal axis X is transverse to the longitudinal extension L, the center transverse axis is also transverse to the longitudinal extension L, the other edge region 109, which comprises the strip 1, 2, 3, is arranged on the region of the joint 19 facing the pressurized water side - for example the outer side 116 of the edge region 109 is flush or aligned with the outer side 107 of the wall or joint wall of the tunnel segment.

Due to the so-called terminal arrangement of the expansion joint tape of the joint sealing device, such as facing the pressurized water side 112, the area of the joint 19 that is not filled by the expansion joint tape is or can be filled with a filling material or with other plastics, such as polystyrene panels and the like. In the one area of the joint that faces the interior or the inside 114 of the walls 119 of the tunnel segments, a joint closure tape 111 can be arranged in a U-shaped cross-section in such a way that the joint closure tape 111 can accommodate polystyrene panels or other filling material in the space delimited by its two legs and the section. By providing the sides or outer sides 4 of the legs of the joint closure tape 111 with webs 5, the head areas 6 of which can also have expansion tapes, the sealing is significantly increased.

Instead of the joint tape, a compression tape arrangement can also be used as a joint sealing device for the joint sealing device. In exemplary embodiments, conventional plastic-like materials such as PVC, NBR, PE, PP, TPE, SBR, EPDM, CR, MR as representatives of the comprehensive group can be used as plastic-like materials for the expansion joint tape 1, 1a, for the joint sealing tape 111 and/or the compression tape. These can also additionally contain proportions of plastic-like materials that swell or swell in water.

In a completely different embodiment, the permanently highly resilient joint sealing device comprises, in addition to the expansion joint tape as a joint sealing device,
a strand-like joint closure strip 111, which is formed from a plastic-like elastic material; this is U-shaped in cross-section with two legs connecting a section, on the outer sides 4 of which webs 5 are formed running along its central longitudinal axis X, which can be embedded with its webs 5 in a mass, in particular a concrete-like mass or plastic-like mass or material, or which receives it. The outer sides 4 of which are intended to lie flat against or against the joint side 19a of the concrete-like mass which delimits the expansion joint.

The joint sealing device for the permanent, reliable sealing of joints between or in structures 41 and/or parts thereof, in tunnel structures, comprises an expansion joint tape for the internal sealing of joints and a compression tape arrangement for sealing joints 19 of structures 41 adjacent to outer sides 71 of the outer walls 41a.

Advantages of the expansion joint tape, the permanently highly resilient joint sealing device and its use:

• The expansion joint tape, the permanently highly resilient joint sealing device, the sealing arrangement and the use thereof are characterized by
• a high and uniform expansion capacity in all directions,
• safe position in adjacent building parts,
• highly resilient bridging of the joint gap regardless of temperature changes, shrinkage of the concrete, lack of rigidity of the construction,
• Preventing the penetration of liquids and the creeping of moisture even in the presence of capillary forces,
• Firm embedding of the webs in cast parts of the structure despite structural parts moving away from each other,
• permanent, reliable sealing of joints, such as edge joint areas, between or in buildings,
• exceptional sealing capacity under high water pressure, especially in tunnel structures and parts thereof,
• Safe sealing to the outside and inside,
• guaranteed tensile strength in the stretching or straining area between the sealing strip and the webs formed onto the sealing strip,
• strong load-bearing capacity also due to expansion and liquid-tight closure between the structural parts without penetration of water from the outside to the inside into the gap bridging the joint and vice versa,
• Avoidance of permanent control even under heavy loads due to stretching, compression and strain without tearing the webs out of the concrete,
• e.g. usability of the expansion joint tape as a construction joint tape.
• Due to the clever interaction of the features of the expansion joint tape and the permanently highly resilient joint sealing device, such as the tapering of the webs 5 from their web necks 5c towards their web feet 5b, the tapering of the wall 82 delimiting the cavity 3 on the web side from its end areas 81 towards its central area 80, and due to the interaction of the other features of the expansion joint tape, such as the ratio of the circulation path U to the thickness D, etc.,
• the high degree of elasticity of the expansion joint tape 1,
• the high resilient elasticity of the same, in particular of the webs 5 and the sealing strips 2 connected to the webs 5 by molding,
• the permanent sealing between the expansion joint tape 1 and the joint sides 19a delimiting the joint 19 in the presence of the relative movements frequently observed in building components, such as drifting apart, moving towards each other and/or strains,
• especially since the webs 5 reliably remain in place in the building materials they contain, e.g. concrete, mortar, and the like.

Furthermore, the sealing strip 2 also remains sealingly connected to the aforementioned building materials, supported by the stationary webs 5, or is sealingly attached against them, whereby the projections 10 formed on the sealing strip 2 and the high circulation path greatly increase the moisture distance that the moisture would have to take in order to get from the inside of the joint via the expansion joint tape to the outside or from the outside to the inside into the joint, so that the expansion joint tape, in comparison to the state of the art, can meet any sealing requirements that are placed on joint seals in tunnel structures in particular.

• Haltesicherheit,
• Dichtigkeit,
• Dauerhaftigkeit der Verbindung,
• Ortstreue,
• so dass der Durchlass von Feuchtigkeit, die von innen aus der Fuge 19 über die Kompressionsbandanordnung nach außen oder von außen nach innen in die Fuge 19, z.B. infolge Kapillarkräften, zu kriechen vermag, auch bei Auftreten der vorgenannten, gerade bei Tunnelbauten auftretenden, Relativbewegungen, wie Auseinanderdriften, Zueinanderbewegungen oder Zerrungen der Bauteile derselben, zuverlässig und dauerhaft unterbrochen ist und die im Stand der Technik geforderten überaus häufigen Kontrollen auf ein angemessenes und erträgliches Maß verringert werden können.

In addition, the compression band arrangement proves to be of sufficient

• Holding security,
• Tightness,
• Durability of the connection,
• Local loyalty,
• so that the passage of moisture, which can creep from the inside of the joint 19 via the compression band arrangement to the outside or from the outside to the inside into the joint 19, e.g. as a result of capillary forces, is reliably and permanently interrupted even when the aforementioned relative movements occur, which occur particularly in tunnel constructions, such as drifting apart, moving towards one another or straining of the components thereof, and the extremely frequent checks required in the state of the art can be reduced to an appropriate and tolerable level.

Finally, the permanently highly resilient joint sealing device, such as the combination of the expansion joint tape and the compression tape arrangement, and the sealing arrangement, also cleverly combines the aforementioned advantages resulting from technical successes in such a way that the joint sealing device is suitable for use in any building structure and its components.

• die Dichtheit der Dehnungsfugen zwischen Tunnelsegmente bei Bodensetzungen,
• die einfache Verlegung,
• die Toleranz gegenüber Druck- und Zugkräften,
• die dauerhafte zuverlässige Dichtheit der Dehnungsfugen von Tunnelsegmenten bei unterschiedlichsten Bewegungen derselben, wie Auseinanderdriften, Stauchungen, Zerrungen,
• den weitgehenden Entfall von Kontrollen,
• den Entfall der Wartung,
• die fehlende Beschleunigung der Materialermüdung gegenüber Druck- und Zugkräften, usw..

The expansion joint tape, the permanently highly resilient joint sealing device and the use of the same in tunnel construction are also characterized by

• the tightness of the expansion joints between tunnel segments in the event of soil settlement,
• the easy installation,
• the tolerance to compressive and tensile forces,
• the permanent, reliable tightness of the expansion joints of tunnel segments in the event of a wide range of movements, such as drifting apart, compression, strain,
• the extensive elimination of controls,
• the elimination of maintenance,
• the lack of acceleration of material fatigue under compressive and tensile forces, etc.
