Definitions

  • 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.
  • a strand-shaped sealing profile made of an elastomeric plastic, for example rubber or rubber-like plastic, which can have open or closed grooves running lengthways on its base side and usually also channels running lengthways.
  • 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.
  • expansion also known as drifting apart
  • compression also known as moving towards each other
  • strains also known as opposing movements
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • expansion joint tape and the joint sealing arrangement to be provided should also seal the gap between the structures against high water pressure.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the invention also relates to a permanently highly resilient joint sealing device which comprises an expansion joint tape, preferably running in the form of a strand, for the permanent, reliable sealing of joints, also called expansion joints, between or in structures and/or parts thereof with an elastic material, in particular of expansion joints between structures, such as tunnel segments, with a sealing strip.
  • an expansion joint tape preferably running in the form of a strand
  • the use of the expansion joint tape according to the invention also relates to the use of the expansion joint tape as a construction joint tape.
  • 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.
  • 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.
  • 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.
  • 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 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.

  • 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.
