Description

The invention relates to an expansion joint tape for the permanent, reliable sealing of joints between or in buildings and/or parts thereof with an elastic material, with a sealing strip, wherein the sealing strip has continuously extending cavities running along its central longitudinal axis, at least three webs running along the central longitudinal axis are formed on the sides of the sealing strip, the elastic material comprises plastic-like and/or rubber-like material, the webs are formed on the sides of the sealing strip in a central region of the cavities of the sealing strip, the cavities are equally spaced from one another, the sealing strip is rectangular in cross-section, a method for the reliable, permanent sealing of a joint between concrete walls and a joint sealing arrangement for the permanent, reliable sealing of joints between or in buildings and/or parts thereof.

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 there is little or no movement. Movement joints are pre-planned interruptions in components. The width of a movement joint can change. When the building is heated, e.g. due to sunlight, the building components expand and the movement joints become narrower, whereas the opposite process is often observed when cold snaps occur. Construction joints, which also need to be sealed, occur when, 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 bands.

The prior art discloses a joint tape which consists of a deformable, channel-like middle part and strips which are connected to the side of the middle part and on which strip-like beads with a mushroom-like cross-section are formed on one side. The laterally connected strips are embedded in concrete to firmly couple the side bands to the concrete. However, it turns out that the structural parts move relative to one another. The relative movements are shown in a so-called expansion due to the structural parts drifting apart from one another. The drifting apart of the structural parts 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 when the structural parts move relative to one another.

The BE 549 247 A The joint tape disclosed with a central piece, side bands formed on the central piece and several webs formed with their broad bases on the top and bottom of the side bands is deformable, but it has the disadvantage that the conventional joint tape is pulled out of the concrete when even small relative movements of the adjacent components occur due to the slight support in the concrete. The deformability of the joint tape is essential, however, since the relative movements of components already occur due to temperature changes, shrinkage of the concrete, lack of rigidity of the structure or different composition of the building materials of adjacent components with different thermal expansion coefficients.

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.

The FR 1 074 307 A The sealing strip disclosed comprises five cavities running in the longitudinal direction, which are rectangular in cross-section. Webs are formed on the opposite sides of the sealing strip. Sealing strips with a circular cross-section are formed on the two opposite ends of the sealing strip, each of which has a cavity with a circular cross-section. Extensions can also be formed on the two opposite ends instead of the two sealing strips. The conventional sealing tape can be placed against the two walls delimiting the gap in order to bridge the gap, but it turns out that the conventional sealing tape with its sealing strips does not remain stationary in a building as a result of vibrations acting vectorially on the sealing tape in a transverse direction to the sealing tape, but moves in a transverse direction to the longitudinal webs with its webs out of the concrete surrounding them, so that leaks occur and liquid, such as water or moisture, can penetrate into the gap via the gaps thus exposed between the webs and the concrete, which is a disadvantage.

Therefore, it is also an object of the invention to provide an expansion joint tape which acts as an anchor and permanently connects to the mortar surrounding the expansion joint tape in order to prevent the expansion joint tape from becoming detached from the concrete in the event of movements of structural parts which are vectorially directed, for example, transverse to the longitudinal extension of the expansion joint tape.

That the FR 1 248 986 A underlying joint tape profile with a central section and side bands formed on both sides of the central section as well as on the top and The underside of the same molded webs is only slightly deformable because the middle part is solid and the webs merge with their base into the side bands, so that the conventional 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 should offer such a large surface area in the event of liquid penetration that the penetration 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, which are firmly embedded in the parts of the structure, should also move along with the parts of the structure as they move 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 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 sufficient 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 to be provided should also prevent the webs from tearing out of the concrete when it is 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 compression band arrangement should also be able to bridge the large gap widths between structural components, such as those between tunnel structural components, caused by seismic events such as earthquakes or high-speed rail traffic, without impairing the waterproofing, soundproofing and heat-insulating properties of the expansion joint tape and the compression band arrangement.

In addition, the expansion joint tape and the compression tape 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 compression tape arrangement should show largely gradual compensating movements under load in order to avoid material fatigue caused by point loading.

Likewise, the expansion joint tape to be provided and the compression tape arrangement should enable such a sufficiently 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 problem is solved by the main claim and the auxiliary claims. The auxiliary claims relate to preferred embodiments and further developments of the invention.

The expansion joint tape according to the invention can have a ratio of the circulation path or distance to the thickness of the sealing strip in a range from 10.0 to 30.0, preferably 15.0 to 25.0, even more preferably 20.0 or 21.67 or 23.0. In the sense of the invention, 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 expansion joint tape. For the purposes of the invention, the term “circumferential path or distance” can also be understood in the cross-section of the expansion joint tape as the sum of the distances between the sides of the sealing strip between the webs, the widths of the webs or the widths of the head regions, the lengths of the web sides of the webs, preferably as a one-sided circumferential path related to one side or as a two-sided circumferential path related to both sides of the sealing strip or the expansion joint tape. For the purposes of the invention, the term “circumferential path or distance” can also be understood in the cross-section as the sum of the distances between the sides of the sealing strip between the webs, the circumferences of the head regions bordering the web sides, the lengths of the web sides of the webs, preferably as a one-sided circumferential path related to one side or as a two-sided circumferential path related to both sides of the sealing strip or the expansion joint tape.

In a further embodiment of the expansion joint tape according to the invention, the thickness of the sealing strip corresponds to the distance between the head regions 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 can also be 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 have a value of 2.5 to 5.0, preferably 3.0 to 4.0, even more preferably 3.75. In the sense of the invention, edge thickness is also understood to mean the distance between the sides of the sealing strip in the region of the edges thereof. In addition, it is possible for the ratio of the, preferably edge, thickness of the sealing strip 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 3.00.

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 also referred to as the ratio, in particular V2, of the invention. 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 from 2.0 to 5.0, preferably 3.00 or 4.0, and is also referred to as the ratio V3.

To increase the sealing extensibility of the expansion joint tape according to the invention, in a further embodiment of the expansion joint tape according to the invention, 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 cavity side or 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 cavity side or 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 cavity side or 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 cavity side or 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 in cross-section 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 equally spaced 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 channels in the head areas of the webs accommodate swelling bands running lengthwise in them.

Suitable materials for the expansion bands are conventional materials that swell in the presence of liquids, such as plastics that swell when exposed to water or non-rotting or low-rotting natural materials that swell when exposed to water, other swellable coatings; particularly suitable materials are those that are rot-proof, age-resistant, resistant to UV rays, ozone, atmospheric oxygen, bitumen-proof, oil-proof, heat-resistant, petrol-resistant and/or waterproof.

The sealing strip runs along the central longitudinal axis; the sealing strip is rectangular in cross-section, with projections running along the central longitudinal axis as sealing lips, preferably with a triangular cross-section; 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 special 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 cross-section, the cavities have side walls that are drawn in towards the webs so that the distance between one side of the sealing strip and the cavity side or side wall of the cavity of the sealing strip facing this or one side, which distance concerns or faces the edge of the sealing strip, is greater can be 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 cavity side or 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 sides 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 or both sides and/or towards the edges on one or both sides; for example, the thickness of the side wall of the sealing strip delimiting the cavity can reduce 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.

As a result of the properties brought about by the above-mentioned configurations of the expansion joint tape according to the invention, the expansion joint tape according to the invention is suitable for sealing installation in a joint as an internal part of the joint, whereby the expansion joint tape according to the invention can be aligned in particular along the joint. In the sense of the invention, an internal expansion joint tape according to the invention is also understood to mean that the expansion joint tape according to the invention is arranged in the joint at a predetermined distance from the outside of the outer walls.

In one embodiment of the expansion joint tape according to the invention, the ratio (such as A7/B2) of the distance between two adjacent webs to the width of the head region is 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 invention is not directed 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 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 projections running along the central longitudinal axis in cross section, which act as sealing lips for anchoring in buildings or parts thereof and for sealing; this expansion joint tape differs from the expansion joint tape according to the invention described above and below in that the sealing strip is not formed with cavities; nevertheless, the designs mentioned above and described 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 according to the invention in structural parts as a result of concrete casting, there is a sufficient stationary coupling or embedding of the expansion joint tape according to the invention with its webs in the concrete, so that the expansion joint tape according to the invention not only compensates for movements that occur simultaneously, for example strains and compressions or strains and expansions, while sealing the joint between structural parts, between structures and/or in them, but also helps to avoid the tearing observed in the prior art due to the limited expansion capacity of conventional joint tapes, which is conventionally not limited in terms of position. The webs and the exceptional proportions 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 according to the invention 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 structures to each other, and to seal the space between the sealing strip and the inner joint walls of the joints of the structures in a water-proof manner. to seal. In the sense of the invention, an expansion joint tape can also be understood as a construction joint tape. In the sense of the invention, an 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; in the sense of the invention, a 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.

In other embodiments of the expansion joint tape according to the invention, the web tapers continuously or interrupted in cross-section from its web neck, which faces away from the sealing strip, towards its web foot, which faces the sealing strip: Thus, in cross-section, the width of its web foot can be 5 to 30% or 10 to 25%, preferably 15 to 20%, even more preferably 16% or 17.55% or 18% or 25% smaller than the width in the region of its web neck; to maintain elasticity, the web sides of the web, which taper in cross-section from the web neck to the web foot, prove to be advantageous, e.g. to support the sealing of the gap bridging the joint between components that are moving away from each other. For the purposes of the invention, the width of the web neck of the web is also understood to mean the distance between the web sides of this web that face the head area, and the width of the web foot of this web is also understood to mean the distance between the web sides of this web that face away from the head area. For example, the width of the web neck of the web includes the distance between its web sides without projections or the distance between the projections of its web sides or their tips that face the head area; to maintain elasticity, the web sides of the web that are tapered in cross section from the web neck to the web foot are advantageous, for example to support the sealing of the gap bridging the joint of components. For the purposes of the invention, the width of the web neck of the web is also understood to mean the distance between its web sides without projections or the distance between the projections of its web sides or their tips towards or from each other that face the head region, and the width of the web foot of this web means the distance between the web sides of this web towards or from each other that face away from the head region. Compared to the width of the web sides, the distances between the projections on the opposite web sides can be negligible. In further embodiments of the expansion joint tape according to the invention, due to the small size of the projections compared to other parts of the same, such as sides, webs, these can also be negligible in size and dimensions. With the aid of the method according to the invention, a joint between concrete walls to be constructed is sealed by placing a protective shoe, e.g. containing a plastic, metal material and/or wood, against one side region of the expansion joint tape to accommodate the webs in preformed, e.g. channel- or tube-shaped, web spaces; the clear width or inner diameter of the same can be modeled on the width B2 of the head regions of the webs or at least part of the inner walls of the web spaces can be modeled on the outer contour of the webs. Slats or strips, which can contain e.g. a plastic, a metal material and/or wood, are placed against the edges of the expansion joint tape according to the invention along the central longitudinal axis of the expansion joint tape according to the invention to protect the edges of the expansion joint tape from damage. The paneled space accommodating the other side region of the expansion joint tape according to the invention with the webs and a steel reinforcement is then poured with concrete. After the concrete has hardened, the protective shoe is removed and the paneled space accommodating one side region of the expansion joint tape with the webs and a steel reinforcement is poured with concrete; After the concrete has hardened, the battens or strips are removed, e.g. conventional sealing strips are then placed against the edges of the expansion joint tape and/or the compression tape arrangement is inserted between the joint sides of the external walls of a building that border the joint. The special properties caused by the above-mentioned designs of the expansion joint tape according to the invention lead to the desired permanent joint sealing, even despite the relative movements observed in the building parts, such as expansion (drifting apart), Compression (movement towards each other) and/or strain (opposite movements along the vertical).

In embodiments of the compression band arrangement, the inner jaw and the outer jaw can be inelastic; they can contain a metallic material such as steel, aluminum, etc. The sealing band, also called compression band, is elastic; it can be extruded with a plastic-like material, such as a material bond, or co-extruded from various plastic-like materials. Suitable plastics or plastic-like materials can be thermoplastic, thermoplastic elastomers, elastomers or other plastic-like materials and/or rubber-like materials. These can be made from PVC, PVC/NBR (nitrile/butadiene plastic-like materials), TPE, PE, PP, elastomer mixtures or other elastomers that can be deformable or re-deformable. The outer jaw can be rectangular in cross-section, the inner jaw can taper in the direction of the compression band or be tapered.

In one embodiment of the compression band arrangement for the permanent, reliable sealing of joints, such as, preferably edge-located, joint areas between or in structures, preferably tunnel structures, and/or parts thereof, the channels accommodate expansion bands to increase the sealing. The compression band can be compressed. As a result of the force applied during the transition from the starting position or open position to the end position or sealing position by screwing the screw into the inner jaw, by shortening the distance between the inner jaw and the outer jaw, 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. The shortening of the distance between the inner jaw and the outer jaw along a straight line enables the desired positionally accurate and uniform application of force to the compression band, so that it is compressed and the compression tape is evenly applied to both sides of the joint and the gap bridging both sides of the joint or 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 inner jaw can be U-shaped. The inner jaw and/or the outer jaw can have tapered elevations in their cross-section in their areas facing the compression or sealing band, which engage in the compression band in a force-fitting, friction-fitting 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 the inside. The compression band arrangement is particularly suitable for sealing installation in a joint transversely and/or longitudinally to it,

In the design of the expansion joint tape according to the invention with three pairs of webs on both sides of the sealing strip, a largely observe a temporal sequence of gradual movements, whereby firstly the sealing strip is predominantly stretched or compressed under load, under heavy load the webs are stretched but the webs with their head areas remain hooked in the concrete in a positionally accurate and watertight manner, then the side walls arranged between the cavities and webs, to which the webs are formed, are stretched but do not tear because of their increasingly tapered or reduced thickness towards the webs, but under greater load the cavities in the sealing strip are deformed but the webs remain hooked in the concrete in a sealing manner, so that the expansion joint tape according to the invention is characterized by a permanent anchoring in the joints of the buildings and thus a sealing of the space or gap, also known as an internal joint, between the internal joints of the buildings that accommodate the webs and the webs of the expansion joint tape according to the invention.

• wie auch bei häufig sich einstellenden Hin- und Rückbewegungen derselben,
• ohne dass Risse oder Spalte in dem erfindungsgemäßen Dehnungsfugenbandes im Gegensatz zum Stand der Technik aufzutreten vermögen.

The sequence of step-by-step expansions of the expansion joint tape according to the invention 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 being able to occur in the expansion joint tape according to the invention, in contrast to the prior art.

The expansion joint tape according to the invention also seals joints between the structures, regardless of the extent of the thermal and/or seismic movements, against the ingress of water and sound 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 according to the invention is that the higher the water pressure to which the expansion joint tape according to the invention is subjected, the more effectively the expansion joint tape according to the invention seals.

The mushroom- or T-shaped geometry of the webs of the expansion joint tape according to the invention 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 according to the invention, due to the skilful interaction and cooperation

• 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
  and or
• the design of the webs with their advantageous dimensions,
• For the first time, the expansion joint tape according to the invention can be adapted in a quasi-intelligent manner to a wide variety of movements, often overlapping, of neighbouring structures and water pressure
• 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.

In the sense of the invention, bridging of joints of buildings is also understood to mean the spanning or overlapping of joints between adjacent Structural 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 structural parts, so that the adjacent structural parts can be connected to one another, for example to close or limit the joints. In the sense of the invention, a joint is also understood to mean the space between two components.

The expansion joint tape according to the invention 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 according to the invention can also be extruded from a plastic-like material, such as a material bond, 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, thermoplastic elastomers, elastomers or other plastic-like materials and/or rubber-like materials can be suitable as plastics or plastic-like materials. These can be made from PVC, PVC/NBR (nitrile/butadiene plastic-like materials), TPE, PE, PP, elastomer mixtures or other elastomers that can be deformable or re-formable.

In the sense of the invention, expansion joint tapes are also understood to mean that they can be installed inside and/or outside, or construction joint tapes or joint sealing tapes, e.g. for flush closing of a joint, which can be installed inside or outside. In the sense of the invention, expansion joint tape is also understood to mean bridging a gap or space 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 to be poured onto it. When installing or installing expansion joint tapes, the formwork can be slit at the point where the conventional joint tape is to be installed in such a way that the middle part of the expansion joint tape can fit into this slot, the side Part of the expansion joint tape can be tied 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 usually 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.

In the context of the invention, joints are also understood to mean standing joints, movement joints, construction joints and dummy joints. Standing joints are understood to mean joints in which no or only slight movement can occur. Movement joints can be pre-planned component interruptions in certain sections, 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 required during the construction of a structure, when changing building materials, e.g. prefabricated supports and masonry.

The expansion joint tape according to the invention can be extruded in one piece from a plastic-like material. In the sense of the invention, one piece is also understood to mean that it can be produced as a whole, e.g. extruded. The expansion joint tape according to the invention can contain an elastic, compressible material; the expansion joint tape according to the invention can also be fabric-reinforced, such as textile-reinforced. The textile reinforcement of the expansion joint tape according to the invention can be an extensible textile fabric that is 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 middle part, the end parts, the intermediate parts, the channels and/or the grooves extend longitudinally or parallel to the Centre 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 according to the invention enables sufficient sealing of the joints between structures, regardless of their relative movements to one another.

• bei Dehnungen, wie Auseinanderdriften der Bauwerke voneinander,
• bei Stauchungen, wie Zueinanderbewegungen der Bauwerke zueinander
  und
• bei Zerrungen, bei Bewegungen der Bauwerke zueinander parallel zu der Lotrechten, da
• die Beobachtung zeigt, dass bei Zugbeanspruchung die Stege und die den. Stegen benachbarten Seitenwände des erfindungsgemäßen 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 expansion, such as drifting apart of the structures,
• in the case of compression, such as movements of the structures towards each other
  and
• in the case of strains, in the case of movements of the structures relative to each other parallel to the vertical, since
• The observation shows that under tensile stress, the webs and the side walls adjacent to the webs of the expansion joint tape according to the invention are stretched as an expansion zone and become narrower in cross-section, whereas the sealing of the joint remains intact.

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

In the case of particularly strong tensile stresses on the expansion joint tape according to the invention, for example in the case of seismically induced expansions and/or strains, the expansion zone in the area of the sealing strip adjacent to the webs may increase in size, but the intimate sealing contact of the webs with the joint sides remains.

In addition, the sealing of the joint or gap between buildings and/or their building parts by the expansion joint tape according to the invention not only concerns the sealing against water, but also against heat and/or sound.

The expansion joint tape according to the invention also proves to be versatile in its use as an expansion joint tape and a construction joint tape, which can be used both internally and externally.

The expansion joint tape according to the invention enables expansion both in the area of the central piece, 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 in the concrete.

The expansion joint band according to the invention enables an expansion of the lateral bands, which also support the expansion of the middle part when several relative movements occur simultaneously, such as compressions with strains or expansions with strains.

Due to the special design of the middle piece in the form of an H-shaped longitudinal cavity, the expansion joint tape according to the invention also enables 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 as a pressure rail is inserted from the outside 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; in this way, a sealing band can be placed against the outside of the sealing band and then a flat profile, e.g. U-shaped in cross section, as an outer jaw can be placed against the outside of the sealing band. A threaded stand as a screw is passed through the holes in the flat profile and the sealing band and screwed into the holes in the inner jaw with internal thread to apply force to the compression band so that it presses against the joint sides. To apply force to the compression band, a hexagon nut can be screwed on, alternatively or additionally, to accommodate the end of the screw facing away from the compression band. The end of the screw facing away from the compression band is then passed through a flat profile to the outside to provide additional cover for the joints and secured in the end position or sealing position using a cap nut.

The joint sealing arrangement according to the invention comprises the expansion joint tape according to the invention 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, plastic-like and/or rubber-like material, with a sealing strip, and the compression tape arrangement, since these can work together for the internal sealing of a joint and for sealing the joint to the outside and/or to the inside.

It is also shown that both the use of the expansion joint tape and the use of the compression tape arrangement provide an unexpectedly permanent joint seal. The sealing inside the joint in or between buildings or in or between parts thereof by the expansion joint tape according to the invention, the sealing of the joint sides bordering the joint, which are close to the outside area of the building or parts thereof, by the compression tape arrangement can also be achieved in combination by using the combination of the expansion joint tape according to the invention and the compression tape arrangement without limiting their technical successes, surprising properties or the advantages that emerge as a result of the technical successes.

The method according to the invention for reliably and permanently sealing a joint between concrete walls by means of a protective shoe and formwork and the method for producing the compression band arrangement can also work together skillfully.

The expansion joint tape 1 according to the invention contains conventional plastic-like material and has a sealing strip 2, the sealing strip 2 having continuously extending cavities 3 within the sealing strip that run along its central longitudinal axis X; on both sides 4 of the sealing strip 2, three webs 5 are formed that run along the central longitudinal axis X and serve as positionally secure or fixed anchors in the concrete. Before installation, the webs 5 are aligned perpendicular to the central longitudinal axis X. Figures 1 to 4 and 10 can thus show the expansion joint tape 1 according to the invention before and/or after installation. In cross-section, in one embodiment, the web 5 tapers continuously 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 cross-section in embodiments, the width of the web neck 5c of the web 5 is 16%, 17.55%, 18% or 20% greater than the width of its web foot 5b. The width of the web neck 5c of the web 5 comprises the distance between its web sides 11 and - or from each other, which face its head region 6; the width of the web foot 5b of this web 5 comprises the distance between its web sides 11 and - or from each other, which face away from its head region 6.

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 of three-quarter circular cross-section running along the central longitudinal axis X. 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. In one embodiment, the head regions 6 of the two outer webs 5 are oval in cross-section and are provided with projections 10 that run along the central longitudinal axis X. Thus, in cross-section, the wall 82 in an embodiment with a cavity drawn in on one side in the shape of a part circle, which wall 82 delimits the cavity 3 in the direction of the web 5, i.e. on the web side, tapers from its two end regions 81, which are arranged between the webs 5 or face the edges 27, in the direction of its central region 80, which is arranged in the region of the web 5 formed on the side 4 of the sealing strip. The design of this wall 82 is of course also implemented in a majority 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, are referred to as side walls 9, 28 to distinguish them from the externally arranged sides 4 of the sealing strip 2.

In another embodiment with a cavity 3 drawn in on two sides in a partially circular shape, the two opposite walls 82', which 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 tapering of both the webs 5 and the walls 82 in cross-section significantly increases the resilient adaptability and elasticity of the expansion joint tape 1 according to the invention in the event of building offset.

The one-sided or two-sided circulation path U in cross-section, which is realized by the expansion joint tape 1 according to the invention, extends the moisture path along which the moisture is forced to creep in order to escape outwards from the inside of the Joint 19 or from the outside to the inside into the joint 19, so that the sealing provided by the positional stability of the webs 5 remaining in the concrete is cooperatively supported. In another exemplary embodiment, 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 on the opposite sides 4 of the sealing strip 2 and on the web sides 11 of the webs 5; the edges 27 of the sealing strip do not have any projections 10 in one exemplary embodiment. The projections 10 significantly increase the moisture distance along which the moisture creeps in order to get outwards from the inside out of the joint 19 or from the outside to the inside into the joint 19, so that the sealing is thereby visibly strongly supported by the expansion joint tape 1 according to the invention. The following and aforementioned disclosed ratios preferably refer to those calculated in the cross-section of the expansion joint tape according to the invention, without having to be expressly identified as such.

In the sense of the invention, the circumferential path U2 is also understood to mean the other side 4 of the sealing strip 2 opposite the one side 4 of the sealing strip 2.

In a further exemplary embodiment, the one-sided circumferential path U corresponds to the width B1 of the sealing strip 2 in cross-section, which corresponds to the distance between the edges 27 of the sealing strip 2. In an additional exemplary embodiment, the two-sided circumferential path U corresponds to doubling the width B1 of the sealing strip 2 in cross-section, with a width B1 corresponding to the distance between the edges 27 of the sealing strip 2. Likewise, in completely different exemplary embodiments, a thickness D or the sum of both thicknesses D can be added to the one-sided and/or two-sided circumferential paths U; the thickness D can correspond to the distance between the two sides 4 of the sealing strip 2, e.g. in the area of the edge 27 thereof.

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. 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 sides 4 of the sealing strip 2 in cross section.

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 compression band arrangement for permanent, reliable sealing of marginal joint areas 19 or bridging and sealing of a joint gap 19b' between or in tunnel structures comprises an inner jaw 31 with an internal thread that can be inserted into the joint area 19 and an outer jaw 32 with an opening that accommodates a screw and is placed against the outer sides 71 of the two joint walls 41a that delimit the marginal joint area 19; a compressible sealing band 33, also called a compression band, is arranged between the inner jaw 31 and the outer jaw 32. The inner jaw 31 has a hole with an internal thread for receiving a screw; During the transition 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 sealingly applying the same against the joint sides 19a delimiting the joint 19. Since the compression band 33 is elastic, it forms a sealing contact in the event of displacement of the outer walls 41 delimiting the joint. In the sense of the invention, edge joints are also understood to mean joints that border on the outer sides 71 of outer walls 41, also called joint walls 41a, or are arranged in the area of outer walls 41.

The mushroom-shaped head regions of the central webs 5 facing away from the sealing strip 2 are drawn in to form channels 7 of part-circular cross-section running along the central longitudinal axis, the channels 7 of which receive expansion bands 7a. The webs are formed on both sides 4 of the sealing strip 2. On the opposite sides 4 of the sealing strip 2 and on the web sides 11 of the webs 5, projections 10 are formed which are triangular in cross section and run along the central longitudinal axis and can be used as sealing lips for anchoring in buildings or parts thereof and for sealing.

Advantages of the expansion joint tape according to the invention, the compression tape arrangement and the joint sealing arrangement according to the invention:
The expansion joint tape according to the invention, the compression tape arrangement and the joint sealing arrangement according to the invention are characterized by

• through 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 according to the invention as a construction joint tape

• das hohe Maß an Elastizität des erfindungsgemäßen Dehnungsfugenbandes 1,
• die hohe belastbare Elastizität desselben, insbesondere der Stege 5 und der mit den Stegen 5 verbundenen Dichtungsleisten 2 durch Anformung,
• die dauerhafte Abdichtung zwischen dem erfindungsgemäßen Dehnungsfugenband 1 und den die Fuge 19 begrenzenden Fugenseiten 19a in Gegenwart der bei Bauwerksteilen häufig zu beobachtenden Relativbewegungen, wie Auseinanderdriften, Zueinanderbewegungen und/ oder Zerrungen,
• zumal zuverlässig die Stege 5 mit den die Stege 5 aufgenommenen Bauwerkstoffen, z.B. Beton, Mörtel, und dergleichen, ortstreu verbleiben.

Due to the clever interaction of the features of the expansion joint tape according to the invention, 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 regions 81 towards its central region 80, and due to the interaction of the other features of the expansion joint tape according to the invention, 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 according to the invention,
• 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 according to the invention 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 one another and/or strains,
• especially since the webs 5 with the building materials held by the webs 5, e.g. concrete, mortar, and the like, remain reliably in place.

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 travel in order to get from the inside of the joint to the outside via the sealing joint tape according to the invention or from the outside to the inside into the joint, so that the expansion joint tape according to the invention is able to meet any sealing requirements that are placed on joint seals in tunnel structures in particular compared to the prior art.

• 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 angemessene 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 in the event of the above-mentioned relative movements, which occur particularly in tunnel constructions, such as drifting apart, moving towards one another or straining of the components thereof, and the The extremely frequent checks required by the state of the art can be reduced to an appropriate and tolerable level.

Finally, by combining the expansion joint tape according to the invention and the compression tape arrangement to provide the joint sealing arrangement according to the invention, the aforementioned advantages arising as a result of technical successes are also cleverly combined in such a way that the joint sealing arrangement according to the invention is suitable for use in any type of building and its components.
