Description

[0001] The invention relates to an easily installable bracket device for aligning a strand-shaped or strip-shaped seal, such as a joint tape, comprising a mounting bracket for receiving the seal, which is provided with the inner sides of at least its leg arms for positioning against the seal, and two rigidly designed arms, wherein the mounting bracket comprises a partially circular section bracket and two leg arms, and the leg arms merge with their one ends into the section bracket. Furthermore, the invention relates to an easy-to-handle bracket device comprising a bracket device. Furthermore, the invention relates to a method for aligning a joint tape using a bracket device.

[0002] In order to manufacture a component of a building or structure from concrete, formwork must be provided to hold the fresh concrete. While formwork is only used temporarily to allow the fresh concrete to harden, it must be tailored to the various components of the building and structure, such as foundations, walls, columns, ceilings, beams, etc. To increase the durability, stability, rigidity, etc. of the structure or part of it, structures and their components are constructed from reinforced concrete using the reinforced concrete construction method. Reinforced concrete can be manufactured using the in-situ construction method. Reinforced concrete is a composite material whose load-bearing capacity is achieved through the interaction of steel and concrete.

[0003] The steel inserts, referred to as metal or steel reinforcement, can be made with reinforcing steel bars and / or reinforcing steel mesh. The reinforcement therefore absorbs the tensile forces, increases the compressive strength of the concrete, and limits the formation of cracks in the component. If, for example, a component of a building or structure cannot be concreted in a single operation, unavoidable construction joints must be planned for before construction begins. When components or structures are joined together, joints arise that can divide the components or structures into individual sections. These must be professionally designed, with the joint seals meeting the requirements of heat, sound, moisture, and fire protection. The joints can accommodate movements of the components, e.g.They may be exposed to horizontal length changes, transverse forces that may act vertically and / or horizontally, mechanical influences such as traffic, chemical influences, expansion and / or contraction in the event of fire, settlement, earthquakes, water, temperature, and wind, and the gap bridging the components or structures may change in size. A joint, within the meaning of the invention, is also understood to mean a space between two components or structures that results from joining them, whereby the components or structures may butt against one another.

[0004] A distinction can be made between movement joints, settlement joints, construction joints, and dummy joints. Movement joints are pre-planned interruptions in certain sections of building components. When exposed to heat or cold, the joint narrows or expands. The joint seal bridging the joint, such as a joint tape, must be able to absorb and seal all movements without damage, regardless of environmental influences, weather conditions, or relative movements of the building components.

[0005] Settlement joints are designed to reduce or prevent constraint forces resulting from differential settlement, e.g., due to unequal subsoil properties or between building sections with very different load distributions. The gap bridging the settlement joint must also be sealed with a joint sealant, such as a joint tape, to ensure that relative movements, for example, do not permanently lead to leaks and allow for differential settlement without stress or cracks.

[0006] Construction joints can occur when an interruption is necessary during the construction of a building. Construction joints also occur when changing building materials, e.g. prefabricated columns, precast columns and masonry. If such a component or structure cannot be concreted in one operation, unavoidable construction joints must be planned for before construction begins. The construction joints must be created in such a way that the forces are reliably transferred through a tight and strong connection between the old concrete and the new concrete or fresh concrete to be poured onto the old concrete and the tightness between the old concrete and the new concrete or fresh concrete to be poured onto the old concrete is maintained. This can be achieved by stepping, interlocking or by installing joint tapes. Joint tapes are mainly used because their elasticity means they can be adapted to on-site requirements.

[0007] For example, the state of the art uses plastic tapes made of polyvinyl chloride. The gap bridging the joint between structural components or structures must be protected by a joint tape against water pressure, such as external hydrostatic pressure from groundwater and backwater, and must be resistant to aggressive water. To maintain the joint tape's position, such as its alignment, relative to the existing concrete when pouring new concrete or fresh concrete on top of it, a secure joint tape arrangement is required, at least when covering the existing concrete with new concrete.

[0008] Even with waterproof concrete, such as waterproof concrete, it is required to provide a waterproof structure made of concrete with high water penetration resistance. However, to create such a structure – even in multiple work steps, with the creation of old and new concrete – construction joints arise that must be sealed with joint tapes, especially construction joint tapes. Their precise definition, such as their orientation, arrangement, and durability, at least up to and including the connection of the new concrete poured into the space defined by formwork to the old concrete, requires the reliable specification of the joint tape in relation to the local conditions of the old concrete to be treated with fresh concrete.

[0009] Waterproof concrete, also known as waterproof concrete, is conventionally impermeable to water but essentially permeable to water vapor. The floor slab and walls are designed as a closed tub that encloses the structure and, according to specified specifications, extends at least above a certain design water level. Such a construction is referred to as a white tub. Construction joints that occur during the construction of a white tub must also be permanently protected against water pressure and against water creeping through cracks and gaps into the interior of the white tub using joint tapes, especially construction joint tapes.

[0010] Since legal regulations, guidelines such as DAfStb guidelines, etc. must also be observed during planning, construction and execution, it is particularly important to ensure that when providing watertight concrete structures in several work steps, no capillary transport occurs through the components, for example via joints and construction joints, i.e. regardless of the hydrostatic pressure and the layer structure of the components.

[0011] Because DIN regulations, e.g. DIN EN 1045-2 / DIN EN 206-1, must be observed when providing components, e.g. those made of waterproof concrete, for the provision of waterproof structures, high demands are placed on the state of the art in terms of joint tapes and their sealing capacity.

[0012] DE 10 2019 005 290 A1 relates to an expansion joint tape for the permanent, self-sealing of joints between or in structures and / or parts thereof, comprising an elastic, plastic-like material extending along the central longitudinal axis of the expansion joint tape. The elastic, plastic-like material contains plastics, such as TPE, that swell in the presence of liquids, such as water. The expansion joint tape has two sealing strips extending in a strand-like manner along the central longitudinal axis. In the relaxed state, the sealing strips have a polygonal, preferably triangular, cross-section. The sealing strips are connected to one another in their adjacent corner regions opposite the outer sides of the sealing strips, preferably via a strand-like web. The web has web sides running parallel to one another.The sealing strips are designed in cross-section in the shape of, preferably isosceles, triangles. The corner areas of the sealing strips merge into the web. The outer sides of the sealing strips opposite the corner areas run parallel to each other. The web sides bordering the web are aligned at right angles to the outer sides of the sealing strips. Strip-shaped ribs are formed on the long sides and / or on the outer sides of the sealing strips and / or on the web sides of the web, running along the central longitudinal axis.

[0013] DE 20 2011 102 524 U1 relates to a joint sealing device for concrete construction, comprising a metal joint plate that can be positioned upright with a support edge on a reinforcement, which has a support element on at least one side that, in the installed state, protrudes transversely from the main plane of the metal joint plate and can be connected to the reinforcement. The support element is a support part fastened to a side surface of the metal joint plate by a fastening section. The support element has at least one support section extending from the fastening section and movable transversely to the metal joint plate, by means of which the metal joint plate can be supported and secured to the reinforcement in the installed state.

[0014] KR 10 2015 0 034 032 A discloses a separating plate of a construction joint for a concrete structure, which is installed in a construction joint of the concrete structure and is suitable for preventing a displacement of a sealing rib during the pouring of concrete.

[0015] CN 113 187 092 A discloses a crack-resistant concrete structure comprising a structural body and a post-cast strip. The post-cast strip is backfilled with expansive concrete and has anti-shrinkage parts attached to both sides.

[0016] Therefore, it is also the object of the invention to support the sealing effect of the joint tape - even with increasing load due to pressing water and / or increasing deformation - to align the joint tape to the local dimensions on site already during the pouring of fresh concrete and also to ensure that the thus aligned joint tape does not deviate from its position or is even deformed by the pouring jet of fresh concrete.

[0017] However, the state of the art does not include any alignment aid, let alone a frame that fixes a plate-shaped seal, e.g. a conventional joint tape, with a steel reinforcement in order to permanently hold the joint tape in its position, adapted to the steel reinforcement.

[0018] Rather, it can often be observed in the state of the art that when new concrete is poured, the joint tape not only changes its original position in relation to the old concrete, but also its shape and form in such a way that the conventional joint tape does not offer sufficient sealing against pressing water, creeping water and moisture penetrating the concrete due to the deformations of the joint tape that occur during pouring.

[0019] Therefore, it is an object of the invention to provide a bracket device which offers the possibility of arranging the joint tape exactly according to the local specifications on site, of aligning it according to the specifications on site, which offers the security that the joint tape neither changes its position in relation to the old concrete when casting with new or fresh concrete, nor does the joint tape change its shape or its orientation during casting.

[0020] Apart from that, the ironing device to be provided should be easy to handle on site and can be handled reliably even by inexperienced users.

[0021] In addition, the bracket device to be provided should be dimensionally stable so that deformation of the bracket device does not occur when new concrete is poured.

[0022] Likewise, the stirrup device should be designed in such a way that the stirrup device can be coupled to the steel reinforcement in a positionally secure and thus location-accurate manner at least on part of the same in order to prevent a change in the position of the stirrup device, e.g. when pouring with fresh concrete, but also to permanently support the arrangement of the joint tape in the reinforced concrete.

[0023] The problem is solved by the main claims. The subclaims relate to preferred embodiments and further developments of the invention.

[0024] The invention relates to an easily installable bracket device for aligning a strand-shaped or band-shaped, for example plate-shaped, seal, such as a conventional joint tape, with a mounting bracket for receiving the seal in a receiving position, which is provided with the inner sides of at least its leg arms for attachment against the seal, and two rigidly designed arms, wherein the mounting bracket comprises a part-circular section bracket and / or two leg arms, and the leg arms merge with their one ends into the section bracket of the mounting bracket.The leg arms merge with their other ends, facing away from one end, into adjacent first ends of the helically formed arms, and the arms are provided for receiving reinforcement, such as rod-shaped, in particular cylindrical, steel reinforcement, wherein an interior defined by the arms extends along a common central longitudinal axis, the first ends of the arms are spaced apart from one another, the leg arms are aligned transversely to the central longitudinal axis in the rest position, the arms have a number of turns of 1 to 5, preferably two or three, and / or a pitch angle α defined by a straight line applied transversely to the central longitudinal axis of the arms and by a helical surface facing the straight line is less than 90°, preferably in the range between 10° and 75°, even more preferably in a range between 15° and 45°, advantageously 15°, 20° or 25°.

[0025] The invention also relates to an easy-to-handle bracket device with a bracket arrangement according to the invention, possibly according to one of the embodiments mentioned below or a combination of at least two of these embodiments with one another, for aligning a seal in the same. The seal is arranged in the holding position in the mounting bracket, wherein the seal is designed as a joint tape for the permanent, automatic sealing of joints between or in buildings and / or parts thereof, which comprises an elastic, plastic-like material and extends at least partially along its central longitudinal axis, and comprises two sealing strips running in a strand-like manner along the central longitudinal axis, wherein each sealing strip is designed with two longitudinal sides tapering to one another in cross-section to form a corner region and an outer side opposite the corner region.

[0026] One subject of the invention relates to a method for aligning a joint tape with a bracket device according to the invention or a bracket device according to one of the following embodiments or a combination of at least two of these embodiments with each other, characterized by the method steps: spreading the arms of the bracket device during the transition from an initial position to a receiving position by means of a counterforce exceeding the spring force or restoring force of the arms; passing at least a part of a, e.g.cylindrical reinforcement, such as steel reinforcement, by an interior delimited by the two rigid, helical arms in the receiving position; force-loaded application of the arms against the reinforcement in a holding position; spreading apart of the leg arms from one another during a transition from an initial position to a receiving position of the mounting bracket by means of a counterforce exceeding the spring force or restoring force of the mounting bracket; guiding the joint tape or at least a part thereof through an interior delimited by the section bracket, the leg arms and / or the reinforcement or a part thereof in the receiving position; and force-loaded application of the outer sides of the sealing strips against the joint tape in the holding position.

[0027] The bracket device according to the invention for fixing, such as aligning, a, for example, plate-shaped seal, preferably extending along its central longitudinal axis, such as a joint tape, which is suitable for bridging a joint between buildings, between their parts, in the same, has a mounting bracket which is U-shaped or V-shaped in the relaxed state or initial or rest position for receiving the plate-shaped seal in the receiving position, which comprises a part-circular section bracket and two leg arms, one end of which merges into the section bracket, and two arms, the adjacent first ends of which merge into the other ends of the leg arms, wherein the arms in the receiving position are designed to receive rod-shaped, such as cylindrical, reinforcement, such as steel reinforcement, are designed to be helical, and / or preferably on the inside of the leg arms, spikes, such as conically shaped pins,are formed for the point-by-point application of the same against the seal and for the easier centering of the seal in the receiving position in the holding position and the U-shaped or V-shaped mounting bracket with its leg arms under pre-tension is intended for application against the seal in the holding position.,

[0028] A further subject of the invention relates to a method for fixing, such as aligning, a seal, e.g. plate-shaped, preferably extending along its central longitudinal axis, for example a joint tape, with a bracket device by method steps: a) passing a reinforcement, preferably in the form of a rod or cylinder, such as steel reinforcement, or at least a part of it, through the interior defined by the two helical, rigid arms in the receiving position with the arms resting against the reinforcement or spreading the arms during a transition from the rest position to the receiving position, then passing the reinforcement or at least a part of it through the interior defined by the arms or through the interior defined by the arms in the receiving position and then applying a force, such as a spring force, to the arms against the reinforcement in the holding position and / or process steps; b) introducing or passing the seal or at least a part of it into or through an interior space of the rigid mounting bracket delimited by the section bracket, the leg arms, and if necessary also by the reinforcement, in the receiving position with the section bracket, the leg arms, and if necessary also by the reinforcement, resting on the seal or spreading the leg arms apart from one another during a transition from the rest position to the receiving position, wherein the leg arms and / or the section bracket are made of an elastic material, then introducing the seal into the interior space delimited by the section bracket, the leg arms, and if necessary also by the reinforcement or part thereof, or passing the seal or at least a part of it through the interior space delimited by the section bracket, the leg arms, and if necessaryadditionally through the interior space delimited by the reinforcement or part thereof in the receiving position and subsequent force-loaded, such as spring-loaded, application of the same against the seal in the holding position; the process steps a) and b) can also be interchanged in order, so that, depending on the requirements on site, process step a) is preceded by process step b).

[0029] An additional subject matter of the invention relates to a use of the bracket device for fixing, such as aligning, a seal, for example a joint tape, which is e.g. plate-shaped and preferably extends along its central longitudinal axis, with the bracket device by passing at least part of a rod-shaped, such as cylindrical, reinforcement, such as steel reinforcement, through an interior of the bracket device delimited by the two helical arms and / or introducing or passing the seal or at least part of it into or through an interior of the bracket device delimited by the section bracket, the leg arms, if applicable the reinforcement or part thereof.

[0030] The invention can also relate to the use of the bracket device for fixing, such as aligning, a, for example, strand-shaped, preferably extending along its central longitudinal axis, seal, for example a joint tape, with a bracket device by, after spreading out the arms, then passing at least a part of a rod-shaped, such as cylindrical, reinforcement, such as steel reinforcement, through an interior of the bracket device delimited by the two helical arms and then applying force to the arms against the reinforcement and / or after spreading apart the leg arms, inserting or passing through the seal or at least a part of it into or through an interior of the bracket device delimited by the section bracket, the leg arms, if applicable the reinforcement or part thereof and then applying force to the leg arms against the seal.

[0031] The bracket device comprises a mounting bracket which comprises the section bracket and two leg arms formed on the section bracket. In a plan view of the mounting bracket, it is designed with a part-circular, preferably U-shaped or V-shaped, section bracket. The mounting bracket is advantageously made of an elastic material, e.g. a plastic-like material and / or a metallic material. In one embodiment, the bracket device is rigid, i.e. inherently immobile - e.g. without pivoting leg arms or section brackets - by manufacturing it with a metallic material such as steel, iron, aluminum and / or alloys thereof; in another embodiment, the bracket device has pivotable and recoverable leg arms or a pivotable and recoverable section bracket by manufacturing it with a plastic-like material.Due to the preferred elasticity of the mounting bracket, the distance between the opposite or adjacent inner sides of the leg arms due to the lack of pivoting in the rest position, e.g. in the absence of a joint tape to be received by the mounting bracket in the receiving position, can be smaller than the distance between the opposite inner sides of the leg arms due to pivoting of the same, which in the receiving position can have the received seal.

[0032] In the context of the invention, a mounting bracket is also understood to mean a mounting bracket with two leg arms that are connected to one another with a section bracket that is, for example, curved, such as U-shaped, V-shaped or with a square-curved section bracket.

[0033] For the purposes of the invention, the initial position or rest position of the bracket device or the mounting bracket is also understood to mean the mounting bracket with leg arms and / or section brackets and / or the arms in an unloaded state.

[0034] In the sense of the invention, the receiving position of the bracket device or the mounting bracket is also understood to mean the receiving of the joint tape in the interior space delimited by the rigid mounting bracket; the application of the joint tape as a result of pressing in the sections of the joint tape adjacent to the leg arms of the elastic mounting bracket, so that the joint tape, due to its elasticity and recovery capacity, is applied against the leg arms and / or the section bracket of the mounting bracket and the joint tape can remain in the interior space delimited by the leg arms and section bracket largely between the pivot arms in the holding position for permanently determining the arrangement and orientation of the joint tape in the interior of the mounting bracket.Although the holding position in the sense of the invention can also be seen or understood as a component of the receiving position, since in the receiving position the joint tape is or is received in the interior, the distinction between the receiving position and the holding position facilitates the principle of the invention, because in the holding position essentially the force-loaded attachment of the leg arms and / or the section bracket, etc. and thus the permanent force-, friction- and / or form-fitting fixing of the joint tape in the mounting bracket can take place.

[0035] For the purposes of the invention, the receiving position of the bracket device or the mounting bracket is also understood to mean the elastic mounting bracket with its elastic leg arms and / or its elastic section bracket with the spreading apart of its leg arms and / or the section bracket to increase the distance between the leg arms and to receive the joint tape; as a result of the spreading back of the same in the direction of the joint tape, in the holding position the pivot arms and / or the section bracket are placed against the joint tape in the mounting bracket and the joint tape remains in the interior space between the pivot arms delimited by the leg arms and section bracket.Although the holding position in the sense of the invention can also be seen or understood as a component of the receiving position, since in the receiving position the joint tape is or is received in the interior, the distinction between the receiving position and the holding position facilitates the principle of the invention, since in the holding position essentially the force-loaded attachment of the leg arms and / or the section bracket, etc. and thus the permanent force-friction and / or form-fitting fixing of the joint tape in the mounting bracket can take place.

[0036] In the sense of the invention, the receiving position of the stirrup device is also understood to mean the receiving of the reinforcement in the interior delimited by the rigid arms of the stirrup device, so that at least a frictional and / or positive connection between the reinforcement and thus the arms can be made possible for a permanent fixation of the reinforcement in the interior.

[0037] For the purposes of the invention, the receiving position of the stirrup device is also understood to mean the arms with their spreading out to receive the reinforcement and arranging the steel reinforcement in the interior defined by the arms; the spreading back of the same towards the reinforcement with the arms being placed against the reinforcement and the reinforcement remaining in the interior defined by the arms takes place in the holding position. Although the holding position for the purposes of the invention can also be seen or understood as a component of the receiving position, since in the receiving position the reinforcement is or is received in the interior, the distinction between the receiving position and the holding position facilitates the principle of the invention, since in the holding position the force-loaded application of the arms and thus the permanent force-, friction- and / or form-fitting fixing of the reinforcement in the mounting stirrup can essentially take place.

[0038] For the purposes of the invention, prestressing also refers to the force-loaded application of the leg arms against the seal due to the restoring force of the elastic, such as spring-elastic, leg arms, which is directed toward the seal, such as the joint tape, in the receiving or holding position. For the purposes of the invention, prestressing also refers to the force-loaded application of one or both arms against the reinforcement due to the restoring force of the arms, which is directed toward the reinforcement, such as steel reinforcement, in the receiving or holding position.

[0039] For the purposes of the invention, spreading the leg arms apart also includes bending the section bracket. The easy-to-handle bracket device according to the invention comprises the easy-to-install bracket device according to the invention with the seal accommodated in the interior of the mounting bracket of the bracket device, such as the joint tape, and / or with the reinforcement accommodated in the interior of at least one arm of the bracket device, such as the steel reinforcement. In one embodiment of the easy-to-install bracket device according to the invention, the bracket device is formed in one piece. For the purposes of the invention, one-piece construction also means that it can be manufactured, e.g. extruded, with the leg arms, the section bracket and at least one arm as a whole, i.e. in one piece.

[0040] The interior of the mounting bracket, defined by the section bracket and the two leg arms, accommodates a strand-like joint tape, e.g., a sheet-like seal, whose central longitudinal axis can be aligned transversely to the leg arms. Due to the elasticity of the leg arms and / or the section bracket, the leg arms act as springs on the joint tape, so that at least the leg arms are applied against the joint tape, which, in the receiving position, is subjected to a force from the interior of the mounting bracket, e.g., spring-loaded, also called pre-tensioned.

[0041] For the purposes of the invention, bridging joints between structures, between their parts and / or within them also means spanning or overlapping joints between adjacent structural components, such as floor surfaces, etc., 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 components, so that the adjacent structural components can be connected to one another, for example, to close or limit the joints. For the purposes of the invention, a joint also means the space between two structural components, such as tunnel segments.

[0042] In order to facilitate the insertion of the joint tape into the mounting bracket and to prevent it from jamming flatly with the leg arms, in a special embodiment of the bracket device according to the invention, opposing elevations such as spikes or tenons are formed on the inner sides of the leg arms so that in the receiving position the leg arms are placed with their spikes against the joint tape in specific points. The spikes act as spacers to facilitate the alignment of the joint tape between the leg arms in the receiving position and support the positional stability of the joint tape relative to the leg arms and the fixing of the joint tape in the mounting bracket interior in the holding position. In addition, the spikes placed against the joint tape effectively prevent the joint tape from slipping in the interior of the bracket device, which is delimited at least by the leg arms and the section bracket, when poured with liquid concrete in the holding position.Likewise, prongs can be molded onto the inside of the section bracket to assist in positioning the prongs against the joint tape. Suitable prongs can be cylindrical, conical, or tapered, for example.

[0043] Likewise, the distance between the leg arms in the rest position and thus also the distance between the inner sides of the leg arms, which are adjacent and opposite one another and at least partially delimit the interior of the U-shaped mounting bracket, can be smaller in the rest position in the formation of elastic leg arms and / or section brackets than in the receiving position due to the possible retention of an expansion and thus greater spacing of the leg arms from one another due to the inclusion of the joint tape.

[0044] The mounting bracket, which has at least the two leg arms and the section bracket, can also be rigid, so that the mounting bracket of the bracket device is not elastic, but is nevertheless suitable for receiving the joint tape. The mounting bracket in a rigid design is also suitable for receiving the joint tape, since the joint tape, due to its elasticity caused by its manufacture with an elastic, e.g. plastic-like, material, can be easily inserted into the interior space delimited by the leg arms, section brackets, and possibly also by the steel reinforcement inserted into the arms, as a result of the joint tape being compressed or pressed in, such as transversely to its central longitudinal axis, in the sections of the joint tape adjacent to the leg arms. The attachment of the joint tape as a result of pressing in the, e.g.from the leg arms adjacent sections of the joint tape, so that the joint tape is applied against the leg arms and / or the section bracket of the mounting bracket due to its elasticity and recovery capacity, and the joint tape remains in the interior space delimited by the leg arms and section bracket, largely between the pivot arms in the holding position for the permanent determination of the arrangement and alignment of the joint tape in the interior of the rigid mounting bracket.

[0045] In another embodiment of the mounting bracket, it can be elastically designed using an elastic material. For example, the leg arms and / or the section bracket can be made of an elastic material. In one embodiment of the mounting bracket with an elastic, e.g. a plastic-like, material, a force is generated by spreading the leg arms apart from one another and providing an increasing distance between them as a result of the two leg arms being deflected from one another from the stable equilibrium position, which corresponds to the rest position, into the receiving position. Spreading the leg arms apart requires a force, counterforce or expansion force that exceeds the restoring force of the leg arms during the transition from the rest position to the receiving position.This force, also called restoring force, spring force or straightening force, strives to restore the original position and alignment of the leg arms in the rest position. As a result of the transition from the rest position to the receiving position and as the mounting bracket remains in the receiving position, the leg arms are spread apart to such an extent that the joint tape can also be easily inserted into the interior space delimited at least by the leg arms and the section bracket or passed through it. After the joint tape has been inserted into the interior space or passed through it, the leg arms in the holding position largely return to their original position as a result of the restoring force, which approximately corresponds to the rest position in terms of the approach of the leg arms to each other.The restoring force, which can also be referred to as spring force, ensures that the leg arms and / or the section stirrup or part thereof, due to its partially circular design, are applied against the joint tape in the holding position, so that the positional stability of the joint tape is maintained in the stirrup device according to the invention, even when liquid concrete is applied or poured onto it, in the area in which the stirrup device and the joint tape are arranged. Depending on the use of an elastic material, the stirrup device according to the invention can advantageously generate a different degree of restoring force or spring force. Precisely through the use of stirrup devices according to the invention, possibly made of different elastic materials, the stirrup devices according to the invention can also be provided with different restoring forces as desired by the user on site.

[0046] The bracket device according to the invention additionally comprises an arm, preferably two arms, whose first, adjacent ends merge into the other ends of the leg arms, which are opposite one another. The central longitudinal axis of the interior defined by one or both of the preferably helical arms is advantageously aligned transversely to the leg arms. In a particular embodiment of the easily installed bracket device according to the invention, the helical arms can be manufactured with helically wound round, square, and / or rectangular rods. The first ends of the helical arms, which face the leg arms, are advantageously straight, also extending along the central longitudinal axis of the interior defined by the helical arms; preferably, they merge into the other ends of the leg arms, for example, at a right angle.Advantageously, the central longitudinal axis of the inner element is oriented transversely to at least one leg arm. In at least one embodiment of the easily installed bracket device according to the invention, the two central longitudinal axes of the helical arms coincide, so that they form a uniform, common, central longitudinal axis, which can be oriented transversely to the leg arms.

[0047] The arms can be adapted to the outer contour, such as the outer shape, of the steel reinforcement. For example, the arms are helically designed, comprising turns such that the circumferences of the turns with radii of curvature can be aligned with the diametrical radii of curvature of the steel reinforcement to be accommodated in the arms. A turn, within the meaning of the invention, is also understood to mean, when viewed from above onto the interior space defined by the arms with the central longitudinal axis as the center, a fully circular turn or a turn describing a full circle, or the bend thereof describing a full circle. The number or quantity of turns, within the meaning of the invention, is also understood to mean the number of turns describing a full circle or the bends describing a full circle.

[0048] In one embodiment of the arm, it can have a different number of turns, for example two to five turns describing a full circle with a number of turns of 2 to 5, preferably two to three turns describing a full circle with a number of turns of 2 to 3, even more preferably a number of turns of 1, 2, 3 or 4. Likewise, the helical design of the arm can be uniform or have different pitch angles.

[0049] The inner diameter, also called the coil opening or diameter, of the interior defined by the helical arms is understandably smaller in the rest position of expandable, helical arms than in the receiving position, in the case of the received part of a steel reinforcement into the interior of the same. For the purposes of the invention, the coil diameter is also understood to mean the clear width of the interior defined by an arm when viewed from above.

[0050] In a further embodiment of the easily installable bracket device according to the invention, a straight line applied transversely to the central longitudinal axis of the helical arms and the helical surface, which can represent a helical line according to the development, comprise a pitch angle α which is less than 90°, preferably between 10° and 45°, even more preferably between 10° and 25° or 15° to 35° or 15° to 30°, advantageously can be 10°, 15°, 20° or 25°. In the sense of the invention, the helical surface is also understood to mean the surface created by screwing or winding, to which a further straight line can be applied to form the angle by means of the straight line applied transversely to the central longitudinal axis of the helical arms.

[0051] The clear width of the inner or the winding diameter, as well as the radii thereof, also depends on the on-site requirements and the outer diameter of the steel reinforcement to be accommodated, so that depending on the requirements of the physical requirements of the reinforced concrete and the use of steel reinforcement of different diameters, the stirrup device according to the invention can be adapted to the on-site conditions.

[0052] The arms are rigidly constructed, so that the arms, or their coils, cannot be extended or compressed, and the coil diameters remain essentially unchanged. This does not preclude the possibility that, even when using rigid materials, a certain amount of play, such as movement play, may exist between the arm and the reinforcement.

[0053] The arms can be pulled apart or compressed along their central longitudinal axis, for example. The winding openings or the clear width of the interior, which is defined by the arms, can therefore be advantageously adjusted depending on the specifications on site and the outer diameter of the steel reinforcement to be accommodated, such as rod-shaped steel reinforcement. By spreading the arms and widening the clear width by inserting rod-shaped tubular steel reinforcement, a counterforce or expansion force is generated which exceeds the restoring force of the arms during the transition from the rest position to the receiving position, so that in the receiving or holding position the arms are applied with force as a result of the restoring force or spring force and are placed in a positionally stable manner against the surface of the steel reinforcement and remain securely open as a result of the prestress generated by the restoring force.

[0054] The bracket device according to the invention, e.g. with its leg arms, section brackets and / or arms, can be made of a plastic-like material which can comprise at least one representative of the group comprising TPE, PVC, NBR, PE, PP, SBR, EPDM, CR and NR compounds and their derivatives known to the person skilled in the art.

[0055] TPEs include thermoelastic or thermoplastic elastomers, PVC polyvinyl chlorides, NBR acrylonitrile-1,3-butadiene rubber, PE polyethylene, PP polypropylene, SBR styrene-butadiene copolymers, EPDM ethylene / propylene-diene terpolymers, CR polychloroprene rubber, NR isoprene rubber, and / or their derivatives. Both plastics that swell or expand in liquids such as water and plastics that do not swell or expand in liquids such as water can be used to manufacture the leg arms, the section bar, and / or at least one arm of the bar device.

[0056] In a particular embodiment, the plastic-like material can contain plastics that swell in the presence of water, such as TPE, in order to increase the form fit between the bracket device according to the invention and new or fresh concrete after casting with the same, and to also permanently increase the positional stability of the seal in the same. Thermoplastic elastomers, such as TPE, are understood in the context of the invention to be polymers or thermoplastic rubbers that can possess a combination of the performance properties of elastomers and the processing properties of thermoplastics. This can be achieved, for example, if soft and elastic segments with high extensibility and a low glass transition temperature (T g ) as well as hard, crystallizable segments with low ductility, high T gand a tendency toward association formation, such as physical crosslinking. The soft and hard segments are preferably incompatible with each other and exist as individual phases. Thermoplastic elastomers are also suitable if they have thermolabile, reversibly cleavable crosslinking sites, i.e., of both physical and chemical nature. Conventional thermoplastic elastomers, such as styrene-type thermoplastic elastomers, are suitable. These can have butadiene, isoprene, or ethylenebutylene as the soft polymer segments, and styrene compounds such as SBS, SIS, or SEBS as the hard polymer segments.

[0057] For example, thermoplastic elastomers classified into TPE classes 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 containing vinylidene chloride. These are referred to by those skilled in the art as EPDM / PP or NR / PP or EVA / PVDC or NBR / PP. Conventional thermoplastic elastomers, such as polyurethane-type thermoplastic elastomers, are also suitable, as are soft polymer segments with ester glycols and hard polymer segments with isocyanate chain extenders or which have H bonds. Polyetherester-type thermoplastic elastomers, which have alkylene glycol as soft polymer segments and alkylene terephthalate as hard polymer segments, are also suitable.Also suitable as thermoplastic elastomers are polyetheramides, which have etherdiols as soft polymer segments and amides as hard polymer segments. These thermoplastic elastomers can swell in the presence of liquids such as water.

[0058] Other TPE and thermoplastic elastomers that can be used include TPO, such as thermoplastic elastomers based on olifin, SBS, such as styrene triblock copolymers, TP-NR, such as thermoplastic natural rubber, TP-NBR, such as thermoplastic nitrile rubber, TP-FKM, such as thermoplastic fluorine rubber, TP-Q, such as thermoplastic silicone rubber, TPU, such as thermoplastic polyurethanes, CPE, CPA as copolymeric polyetheresters, PEBA, such as polyether block amides and / or MPR, such as melt-processible rubber, etc.

[0059] In addition, the plastic-like material can also contain portions of water-absorbing, thus swelling compounds, 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 by chemical bridge bonds. Although these bridges may be water-insoluble, water molecules can attach to their polar groups. The use of polar polymer compounds in the thermoplastic elastomers further enhances the swelling of the thermoplastic elastomers.

[0060] For the purposes of the invention, sealing is also understood to mean an elastic band that can extend in a strand-like and / or plate-like manner along its central longitudinal axis. For the purposes of the invention, joint tape is also understood to mean an expansion joint tape whose sealing strips, webs, and strip-like ribs are or can be firmly embedded in structural components as so-called sealing lips as a result of material casting, such as concrete casting.

[0061] The following and previous explanations and special embodiments of the bracket device according to the invention relate to the latter in the rest position and / or during or after the joint tape has been installed, before or after installation of the same using new or fresh concrete, such as in a concrete-like mass. New concrete, fresh concrete, or concrete or concrete-like mass can also be understood, within the meaning of the invention, as a mixture or a mixture with cement as a binding agent, gravel sand as an aggregate, water, and optionally other aggregates and / or additives, as required for the provision of structures and / or their parts.

[0062] For the purposes of the invention, a joint tape can also be understood as a construction joint tape. For the purposes of the invention, a joint tape is also understood to mean a seal as a joint tape, the sealing strips of which, with or without ribs or projections, are firmly embedded in structural components as a result of material being poured, such as the pouring of a concrete-like mass, e.g. concrete grouting. For the purposes of the invention, a construction joint tape is also understood to mean a joint tape which, in contrast to the expansion joint tape, can at least also contain inelastic material. The construction joint tape is used when, for example, components cannot be manufactured in a single concreting step. The construction joint tape can run with its central longitudinal axis horizontally or vertically in the component and can be installed half in the first or half in the second concreting step.

[0063] The joint tape has, for example, two sealing strips that can run in a strand-like manner along a central longitudinal axis of the joint tape. Thus, the following and previous embodiments and special designs of the joint tape can relate to the joint tape in the relaxed state, also called the resting state, e.g., before the end of the joint tape is inserted into the clamp device according to the invention or into its interior, before installation or casting with a concrete-like mass, such as concrete, or the like. The following and previous embodiments and special designs of the joint tape can also relate to the joint tape after the end of the joint tape has been inserted into the clamp device or into its interior, with or without concrete filling.

[0064] The sealing strips have a polygonal cross-section. In the sense of the invention, polygonality means that the sealing strips can also be designed as polygons in cross-section, although the two sealing strips can each be connected to one another via a corner region. In the sense of the invention, connecting the corner regions of the sealing strips to one another can also be understood as gluing, fusing both in the transition region, extrusion to produce the one-piece joint tape, or the like. In the sense of the invention, a corner region is also understood to mean an apex angle region, which can be the apex or the intersection point of the two straight lines delimiting the corner region in plan view or in cross-section. The apex angle region has a common apex, which can be arranged on or in the web into which the corner region can transition.The straight lines can usually intersect at this vertex or intersection point, whereby the long sides, e.g., of the corner area(s), of the sealing strips can lie on the straight lines. The polygons, as triangles, can be equilateral, isosceles, right-angled, acute-angled, or obtuse-angled. The sealing strips can also be designed as various triangular shapes. The transition area from the corner area of ​​one sealing strip to the corner area of ​​the other sealing strip can also be designed as a web.

[0065] The joint tape can be extruded with the sealing strips, the webs, the strip-shaped ribs, or these parts, such as webs, can be co-extruded onto the sealing strip. Likewise, the joint tape can be extruded with a plastic-like material, such as a material bond, or co-extruded with various plastic-like materials, whereby certain parts, such as projections that can be used as sealing lips or ribs, can be co-extruded or extruded onto the sealing strip. Suitable plastic-like materials can be the plastic-like material already used to manufacture the ironing device according to the invention, e.g., thermoplastic elastomers or other plastic-like materials that swell or expand in the presence of liquid. These can be deformable or recoverable at a predetermined temperature.

[0066] For the purposes of the invention, joint tapes are also understood to mean those which can be fitted internally and / or externally, or construction joint tapes or joint sealing tapes, e.g. for flush sealing of a joint, which can be fitted internally or externally. For the purposes of the invention, joint tape is also understood to mean bridging a gap or space between two buildings or building components, as well as sealing a building joint between an existing old concrete structure and a freshly poured new concrete structure which is to be attached to it. For the purposes of the invention, polygonality can also be understood to mean that the outside of the sealing strip and / or the outside of the side strip are at least partially partially circular in cross-section when in the relaxed state.

[0067] The long sides of the two sealing strips, e.g. one and the other, are aligned in an X-shape in cross-section and the two opposite side strips formed on the long sides of the, e.g. other, sealing strip are aligned in a cross shape with the same, whereby, e.g. one side strip can be congruent with the other side strip and is aligned transversely to the central longitudinal axis, e.g. equidistant from the long sides, and can be related to the central transverse axis. In the sense of the invention, connection is also understood to mean, for example, gluing, fusing, providing in one piece, etc. In the sense of the invention, the long side of a sealing strip is also understood to mean the extension of one side or leg of the sealing strip from its outer side to its corner region or to the transition region or to the mean distance between the two corner regions.In the context of the invention, the outside of the sealing strip is also understood to mean, for example, the side of the sealing strip opposite the corner area of ​​the sealing strip, such as the base or hypotenuse.

[0068] The two sealing strips are aligned to one another, for example, in such a way that the adjacent corner areas of the sealing strips have a common so-called vertex angle area. For example, the sealing strips designed as isosceles triangles are connected to one another in such a way that their outer sides are aligned parallel to one another as a base and their tips opposite the outer sides can be connected to one another as a corner area, e.g. they can merge directly into one another or merge into a common web. The sealing strips, which are also designed as wedge-shaped in cross-section, can be connected to one another with their acute-angled corner areas as wedge tips so that, in a special design of the joint tape, these tips end bluntly and can merge from both sides of the sealing strips into the common web.

[0069] This web also runs in a strand-like manner, like the sealing strips, along the central longitudinal axis. In cross-section, the apex angles of the apex angle range can each be less than 90°, preferably 1° - 90°, more preferably 2° - 50°, even more preferably 4° - 45° or 6° - 50°, most preferably 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, or 10°.

[0070] The particular advantages of the arrangement of the sealing strips with their aligned and interconnected wedge tips also lie in the special circumstance that the sealing strips are firmly embedded in structural components, such as reinforced concrete walls, as a result of material grouting, such as grouting with a concrete-like mass, e.g. concrete grouting, and interlock in the concrete, so that if the expansion joints of both structural components drift apart, the joint tape does not become detached from the expansion joint. In a special design of the joint tape, the outer sides of the sealing strips opposite the corner areas can be aligned parallel to one another if the sealing strips are designed as triangles. It is also possible for the outer sides of the sealing strips to have a part-circular and / or polygonal cross-section.Likewise, in another embodiment of the joint tape, the two outer sides can be equally spaced from the corner areas or the apex angle areas, so that the tensile forces acting on them can be evenly distributed. The joint tape is particularly suitable if, in cross-section, the distance between the two web sides, which can run parallel to each other, is less than the width of the outer sides of the sealing strips, which corresponds to the distance between the long sides of a sealing strip opposite the corner area. For the purposes of the invention, the width of the outer sides also refers to the distance between the two long sides of a sealing strip in the area of ​​the sealing strips opposite the apex angle area.Thus, the width of the joint tape can also be understood in the sense of the invention as the sum of the length of one web side and the two distances, also called the length of the long side, between the outer sides and the corner areas of the sealing strips.

[0071] The length of the long side of the sealing strip is also understood in the sense of the invention to mean the distance between the outer side of the sealing strip and the transition between this sealing strip and the web. The term web is also understood in the sense of the invention to mean the transition area formed with the preferably parallel outer sides between the corner areas of one sealing strip and the other sealing strip or which connects the two to each other. The term web can also be understood to mean a strip. In addition, the head areas of the sealing strips opposite the corner areas and / or the head areas of the side strips and / or ribs thereof opposite the sealing strip can be interrupted or continuously drawn in to form channels extending along the central longitudinal axis, which channels accommodate swelling or swellable swelling tapes that swell in the presence of water.

[0072] The swelling tapes can additionally contain components of water-absorbing, thereby swelling compounds, 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. Although these bridges may be water-insoluble, water molecules can attach to their polar groups. Due to the use of polar polymer compounds additionally in the thermoplastic elastomers, the swelling of the thermoplastic elastomers is noticeably enhanced. Suitable materials for the swelling tapes include conventional materials that swell in the presence of liquids, such as water-swellable plastics or water-swellable, non-rotting or low-rotting natural materials, and other swellable coatings.Particularly suitable materials are those that are rot-resistant, aging-resistant, resistant to UV rays, ozone, atmospheric oxygen, bitumen-resistant, oil-resistant, heat-resistant, gasoline-resistant, and / or water-impermeable, for example, organic natural materials, organically modified natural materials, organic fully synthetic, and / or inorganic swelling or thickening agents. 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. This swelling visibly supports the waterproofing. The swelling tapes can be impregnated with such swelling agents. Natural and / or synthetic fibers can also be used, which, due to their hydrophilic surface, can absorb water and moisture.Swelling tapes can also be used that are inflated to such an extent that they can attract water and moisture and swell. Swelling agents that can be used include natural organic or 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; and inorganic thickeners, e.g., polysilicic acids, clay minerals such as zeolites, silicas, and / or their derivatives.

[0073] The method according to the invention and the use according to the invention by means of the stirrup device for aligning a joint tape are carried out in such a way that the helical arms can accommodate a rod-shaped, such as a cylindrical or angularly elongated, part of a steel reinforcement, or such a part can be guided through the interior of the helical arms delimited by the helical arms. In a further embodiment, the helical arms can also be prestressed and applied to the outside of the part of the steel reinforcement in order to increase the positional stability of the stirrup device according to the invention and to prevent relative movements of the stirrup device with respect to the steel reinforcement during casting.

[0074] The joint tape is pushed into the interior space defined by the leg arms and spacer bars. Due to the pretension of the leg arms, the leg arms are subjected to a force, such as a spring force, against the long sides of the sealing strips and / or the web sides of the joint tape's web. In a particular embodiment of the method according to the invention, in the case of mandrels formed on the inside of the leg arms and / or spacer bars, the mandrels are applied to the long sides and web sides of the joint tape with a force, such as a spring-loaded force. Furthermore, it has been shown that mandrels formed on the inside help facilitate the adjustment and centering of the joint tape in the interior space defined by the leg arms and section bars.

[0075] Slipping or movement of the joint tape is prevented not only along the leg arms on both sides by the section stirrup on the upper side and the section stirrup connecting the two leg arms, but also by the section stirrup on the lower side, opposite the section stirrup, inserted into the helical arms. By limiting and preventing movement of the joint tape on all sides in the stirrup device according to the invention, the positional stability and thus the positional stability of the joint tape with respect to the steel reinforcement and with respect to the existing concrete are reliably ensured when pouring with fresh concrete.

[0076] It is shown that the stirrup device according to the invention is suitable for any shape and type of joint tape, so that other joint tapes, such as expansion joint tapes, construction joint tapes and the like, can also be coupled to the stirrup device in a centered and precisely aligned manner with the steel reinforcement using the stirrup device according to the invention.

[0077] The method according to the invention and the use of the stirrup device for aligning a joint tape are carried out in such a way that the helical arms receive a cylindrical part of a steel reinforcement or such a part is inserted through the interior of the helical arms delimited by the helical arms or is guided beyond them. In a further embodiment, the helical arms can also be prestressed against the outside of the cylindrical part of the steel reinforcement in order to increase the positional stability of the stirrup device according to the invention and to prevent relative movements of the stirrup device with respect to the steel reinforcement during casting.

[0078] The joint tape is pushed into the interior space defined by the leg arms and spacer bars. Due to the pretension of the leg arms, the leg arms rest against the long sides and / or web sides of the joint tape, both under force and spring force. In a particular embodiment of the method according to the invention, in the case of mandrels formed on the inside of the leg arms and / or spacer bars, the mandrels are resiliently applied against the long sides and web sides of the joint tape. Furthermore, mandrels formed on the inside facilitate the adjustment and centering of the joint tape in the interior space defined by the leg arms and section bars. Examples of implementation

[0079] Due to a simplification of the drawings, the ironing device according to the invention and the ironing apparatus according to the invention are shown schematically and greatly enlarged, without claiming to be true to scale. Fig. 1 the front view of the inventive easy-to-install bracket device without joint tape with the U-shaped mounting bracket and the screw-shaped arms formed on the mounting bracket in the relaxed state, as in the rest position, Fig. 2 the oblique view of the light-handling bracket device with joint tape according to the invention with a part of the steel reinforcement which is not only inserted into the interior of the arms, but also passed through the interior of the same and the joint tape inserted into the interior of the mounting bracket in the receiving position, Fig. 3 the top view of the helical arms of the inventive easy-to-install bracket device without joint tape with a central longitudinal axis extending in the arm in top view, Fig. 4 the oblique view of the inventive easy-to-install bracket device without joint tape in the relaxed state, as in the rest position, and Fig. 5 the side view as a cross-section through the inventive easily installable bracket device without joint tape with the mounting bracket and arms in the relaxed state, as in the rest position.

[0080] In one embodiment of the easily installable bracket device 1, the rigid, inherently immobile, mounting bracket 2 is made of an inelastic, preferably plastic-like and / or metallic material, and the joint tape 20 is provided for application against the inner sides 3c of at least the leg arms 3 by applying the sections thereof adjacent to the leg arms and / or the steel reinforcement 28 is provided for application or placement against the inner sides 5d of the arms 5 in the holding position. In one embodiment of the easily installable bracket device, the recoverable mounting bracket 2 is made of a plastic-like and / or metallic material and, under prestress generated by spring or restoring force, is provided with the inner sides 3c of at least its leg arms 3 for application against the joint tape 20 and / or with the inner sides 5d of the arms 5 against the steel reinforcement 28 in the holding position.

[0081] The easily installable bracket device 1 according to the invention is suitable for securing a seal, in this case the joint tape 20, which runs in a strand-like manner along the central longitudinal axis X, such as a plate-shaped seal, with a U-shaped mounting bracket 2 which is in the relaxed state or in the rest position and is provided for receiving the joint tape 20 in a receiving position under pretension, which mounting bracket comprises a section bracket 4 and two leg arms 3. The leg arms 3 merge with one end 3a of the section bracket 4 and two arms 5 merge with their adjacent first ends 5a into the other ends 3b of the leg arms 3. The arms 5 are suitable for receiving, for example, a rod-shaped, such as a cylindrical or tubular part of the steel reinforcement 28 and are helical in design.On the inner sides 3b of the leg arms 3, spikes 6 are formed as pointed pins, which are formed for the point-by-point application of the joint tape 20 against the spikes 6 and for centering the same.

[0082] The one-piece bracket device 1 according to the invention is made of a plastic-like material, such as TPE. In the rest position, the original distance A of the inner sides 3c of the leg arms 3 to or from each other is smaller than in the receiving position, in which they are at least partially spread open and then applied against the joint tape 20 with force applied. A degree of force remains, since pivoting the leg arms 3 back into the original rest position, such as the relaxed state with the original distance A, may not be possible due to the thickness of the joint tape 20 exceeding the original distance. Prestressing in the sense of the invention is also understood to mean the force which, as a result of the spreading along a pivoting direction Z, e.g.the elastically pivotable or movable leg arms 3 during the transition from the rest position to the receiving position generated restoring force or spring force of the mounting bracket 2, with which the leg arms 3 are applied against the joint tape 20 received in the interior 30 of the mounting bracket 2.

[0083] The two helical arms 5 are made of helically wound round rods and have adjacent ends 5a, e.g., protruding from arms 5, extending straight along the central longitudinal axis LA of the interior defined by the helical arms 5, which merge into the leg arms 3; preferably, the central longitudinal axis LA of at least one of the helical arms 5 is aligned transversely to the leg arms 3. The arms can have two to five turns, preferably two, three, or four.

[0084] The arms 5, for example, act like a helical spring in such a way that, if a part of the steel reinforcement 28 is received in the interior 5c of the arms 5, the screw length SL of the arms 5, which runs parallel to the central longitudinal axis LA of the arms 5, is shortened, and the clear width or inner diameter AL, also called the coil diameter or opening, of the interior delimited by the arms 5 increases. For the purposes of the invention, the coil diameter is also understood to mean the clear width of the interior 5c delimited by an arm when viewed from above in the direction of the arrow (see arrow, Fig. 1). For the purposes of the invention, the number of turns or number of turns also refers to the number of turns describing a full circle or the number of bends describing a full circle. In exemplary embodiments, the arms 5 have two to five turns describing a full circle with a number of turns ranging from 2 to 5, preferably two to three turns describing a full circle with a number of turns ranging from 2 to 3, even more preferably a number of turns of 1, 2, 3, or 4.

[0085] The pitch angle α defined by a straight line 11 extending transversely to the central longitudinal axis LA of the helical arms 5 and the helical surface 12 as part of the helix according to the development or the straight line 11a applied to the helical surface 12 is less than 90°, preferably between 10° and 45°, even more preferably between 15° and 35°, advantageously 15°, 20° or 25°. The pitch angle α defined by the straight line 11 extending transversely to the central longitudinal axis LA of the helical arms 5 and by ... facing away from the viewer in plan view of the arm 5 in this Fig.The pitch angle β of the winding portion extending along the central longitudinal axis 12a shown in FIG. 3 is limited to less than 90°, preferably between 10° and 45°, even more preferably between 15° and 35°, advantageously 15°, 20°, or 25°. Likewise, the helical configuration of the arm 5 can be uniform with a constant pitch angle α and / or β, or the arm 5 can have different pitch angles α and / or β. The second end 5b, as the free end, can be aligned along the straight line 11.

[0086] Since the leg arms 3 and / or the section bracket 4 are made of a plastic-like and / or metallic material, at least the leg arms 3 rest elastically, as if subjected to force, in the receiving position against the joint tape 20 accommodated in the interior of the mounting bracket 2. In the rest position, i.e., without the joint tape 20 being accommodated in the interior of the mounting bracket 2, the mounting bracket 2 is in a relaxed state.In the receiving position, as well as in the holding position as a component thereof, the mounting bracket 2 is subjected to a counterforce which exceeds the restoring force, also called force or spring force, generated by the mounting bracket itself as a result of expansion, in order to easily enable the insertion of the joint tape 20 into the interior of the mounting bracket 2 delimited by the leg arms 3 and the section bracket 4, wherein the leg arms 3 are held spaced apart, for example, by the joint tape and its long sides 22 of the sealing strips 21. In the holding position, the leg arms 3 are pivoted back towards the received joint tape so that they engage in the joint tape 20 under force - pre-tensioned - and the counterforce decreases slightly as a result of pivoting back in the opposite direction to the pivoting direction Z.By the holding position of the mounting bracket 2 of the bracket device according to the invention, the joint tape 2ß is fixed in terms of its orientation and its arrangement.

[0087] The definition of the joint tape 20 in terms of alignment is also understood in the sense of the invention to mean that the joint tape 20, without undergoing any change in shape, apart from pressure points in the same caused by pivot arms 3 and / or section stirrups 4, possibly steel reinforcement 28, is coupled to the steel reinforcement 28, for example vertically or at a predetermined angle with the aid of the stirrup device according to the invention, without the joint tape 20 or parts thereof being bent, but rather the joint tape - virtually in a relaxed state - is held in the mounting stirrup 2 of the stirrup device as on both sides by the leg arms 3 and as on multiple sides or all sides by the leg arms 3 and the section stirrup 4 and / or the steel reinforcement 28.In the context of the invention, the definition of the arrangement of the joint tape 20 also means that the joint tape 20 does not undergo any change in its shape, i.e., no crushing or stretching occurs - which would impair its tightness -, i.e., it is also held in the mounting bracket 2 in an approximately relaxed state.

[0088] It can be seen that precisely by applying force to the leg arms 3, such as spring force, due to the elastic design of the same and / or the section bracket 4, the mandrels formed on the inside of the leg arms 3 and / or on the inside of the section bracket 4 are able to fix the joint tape 20 both point-wise and precisely, and when poured with fresh or new concrete, the fixing of the joint tape 20 desired on site is maintained, in contrast to the prior art.

[0089] The helical arms 5 can also be made of a plastic-like and / or metallic material, so that in the rest position, i.e. without incorporating a part of the steel reinforcement 28 into the interior which is delimited by the helical arms, they have a smaller inner diameter AL or clear width and as a result of the introduction of a part of the steel reinforcement 28, for example a cylindrical part, into the interior along the central longitudinal axis LA of the interior of the helical arms, the length of the helical arms 5 can be shortened and the inner sides of the arms 5 delimiting the interior are applied against the part of the steel reinforcement 28 in a force-loaded manner, such as by a spring force.By inserting the part of the steel reinforcement 28 into the interior, a counterforce is also generated due to the expansion of the interior 5c, which can exceed and counteract the spring force of the helical arms 5, so that due to the force, form, and / or frictional engagement between the helical arms 5 on the one hand and the part of the steel reinforcement 28 on the other hand, the pivotability of the stirrup device according to the invention about the part of the steel reinforcement 28 accommodated in the helical arms can be largely restricted or even prevented, advantageously also to support the fixing of the joint tape. Alternatively, in a preferred embodiment, lateral support arms, which, for example, connect the leg arms 3 to other parts of the steel reinforcement 28, can also fix the orientation of the stirrup device 1 according to the invention (not shown).

[0090] The bracket device according to the invention is also characterized in that the bracket device according to the invention can enclose the plate-like, elongated seal, such as joint tape 20. Thorn-like, e.g. conical or cylindrical, protrusions such as spikes 6 ensure point contact with the plate-like seal. Since the spikes 6 protruding from or protruding from the inner side 36 of the leg arms 3 act as spacers and prevent the joint tape 20 from being applied flatly against the inner side 36 of the leg arms 3, the spikes 6, as a result of their action by the restoring force, may engage deeply in the joint tape 20 and support the positional stability of the joint tape 20 in the interior 30 of the mounting bracket 2. This prevents a water-bearing channel from forming between the bracket device according to the invention and the seal.

[0091] The spiral or helical base points, here helical arms 5, of the bracket device according to the invention support in a unique way the fixing and thus the alignment or arrangement of the plate-like seal in the bracket device according to the invention.

[0092] The helical arms 5 are fastened to the steel reinforcement 28, such as reinforcing steel, in a force-fitting, form-fitting and / or friction-fitting manner.

[0093] The shape of the helical arms allows attachment to reinforcing steel of different diameters.

[0094] At the same time, the screw-shaped arms ensure high positional stability when attached to small rod diameters.

[0095] The ironing device according to the invention can be made of plastic-like and / or metallic and / or rubber-like material.

[0096] It is also possible for the ironing device according to the invention to be made of a two-component material, for example a metallic material such as steel as the inner layer, which is coated on the outside with a plastic-like material.

[0097] Due to the axial shortening of the helical arms 5 as a result of the insertion of a part of a steel reinforcement 28, for example of reinforcing steel, at least a part of the helical arms 5 rests against the part of the steel reinforcement when subjected to force.

[0098] The inner diameter AL of the helical arms 5 in cross-section or the clear width AL or the coil diameter of the helical arms in cross-section increases due to the generated restoring force as a result of the introduction of a part of the steel reinforcement 28, so that due to the force-loaded frictional and / or force-fitting application of the helical arms 5 against the received part of the steel reinforcement 28, the joint tape 20 is also supported in the receiving position on the old concrete, for example horizontally along the central longitudinal axis X of the joint tape 20 and / or to the surface of the old concrete.

[0099] The one-piece joint tape 20 comprises an elastic, plastic-like material extending along its central longitudinal axis X and comprising two sealing strips 21 extending in a strand-like manner along the central longitudinal axis X, each sealing strip 21 being configured with two longitudinal sides 22 tapering to a point in cross-section to form a corner region 23 opposite an outer side 20a of the sealing strip 21 that can be placed against a steel reinforcement 28. The corner regions 23 of the sealing strips 21 are connected to one another in a transition region 25, such as by fusion, adhesive bonding, or extrusion, wherein the transition region 25 is configured as a web 24. The web 24 has two web sides 26, preferably running parallel to one another. The web sides 26 laterally delimiting the web 24 are aligned at right angles to the outer sides 20a of the sealing strips 21.On at least one of the longitudinal sides 22 and / or the outer sides 20a of the sealing strips 21 and / or one of the web sides 26 of the web 24, at least one, preferably two or more strip-shaped ribs 29 are formed as sealing lips, preferably running along the central longitudinal axis X and parallel to one another, e.g., continuously or interrupted. The sealing strips 21 and / or the ribs 29 have a polygonal, preferably triangular, cross-section in the relaxed state. The outer sides 20a of the sealing strips 21 opposite the corner regions 23 run parallel to one another. The joint tape 20 contains elastic plastics that swell in the presence of liquids, such as water, e.g., thermoplastic elastomers, and / or a cavity running along the central longitudinal axis X is formed in the web 24 and / or in at least one sealing strip 21.The sealing strips 21 are formed in cross-section as isosceles, preferably acute-angled or equilateral, triangles, wherein a marking strip is arranged at least on one web side 26 to indicate a predetermined requirement or instruction, preferably an embedment depth in the concrete.
