Description

The invention relates to an easily installable bracket device for accommodating and aligning a strand-shaped seal and/or reinforcement, an easy-to-handle bracket device with the seal and/or reinforcement and the use of the same for accommodating and aligning the strand-shaped, such as plate-shaped, seal and/or the arrangement of the reinforcement in the stirrup device.

In order to be able to produce a component of a building or structure from concrete, it is necessary to provide formwork for receiving the fresh concrete. The formwork is an aid that is only used for a short time to harden the fresh concrete; however, the formwork must be tailored to the different components of the building and structure, for example foundations, walls, columns, ceilings, beams, etc. To increase the durability, stability, rigidity, etc. of the building or part thereof, buildings and their components are made of reinforced concrete in reinforced concrete construction. Reinforced concrete can be produced in-situ. Reinforced concrete is a composite building material whose load-bearing capacity is achieved through the interaction of steel and concrete.

The steel reinforcements, referred to as metal or steel reinforcements, can be made with welded steel rods and/or welded 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 one operation, unavoidable construction joints must be planned for before construction begins. When components or structures are joined together, there are gaps that can divide the components or structures into individual sections. These must be professionally designed, with the joint seals having to meet the requirements for heat, noise, moisture and fire protection. The joints can be exposed to movements of the components, e.g. due to horizontal changes in length, transverse forces that can 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, wind and the gap bridging the components or works than be changed in its dimensions. Within the meaning of the invention, a joint is also understood to mean a space between two components or structures that results from the joining of the same, with the components or structures being able to abut one another.

A distinction can be made between movement joints, settlement joints, construction joints and dummy joints. Movement joints are pre-planned component interruptions in certain sections. When it is warm or cold, the joint expands or becomes narrower. The joint seal bridging the joint, for example a joint tape, must be able to absorb all movements without damage and be able to absorb and seal without damage regardless of environmental influences, weather, relative movements of the components to one another.

Settlement joints are used to reduce or prevent constraining forces as a result of different settlements, e.g. from unequal subsoil properties or between parts of the building with very different loads. The gap bridging the settlement joint must also be sealed with the help of a joint seal, such as a joint tape, in such a way that, for example, relative movements do not permanently lead to a leak in the same and make different settlements possible without tension and cracks.

Construction joints can arise when an interruption is required in the construction of a structure. Construction joints also occur when changing building materials, e.g. prefabricated columns, prefabricated 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 are to be created in such a way that the forces are reliably transmitted through a tight and firm connection between the old concrete and the new concrete or fresh concrete to be cast on the old concrete and the tightness between the old concrete and the new concrete or fresh concrete to be cast on the old concrete is maintained. This can be achieved by stepping, interlocking or by installing waterstops. Essentially, joint tapes are used because these joint tapes can be adapted to on-site requirements due to their elasticity.

For example, plastic tapes made of polyvinyl chloride are used in the prior art. The gap bridging the joint between structural parts or structures must be protected against water pressure, such as against hydrostatically pressing groundwater and backwater, by means of a joint tape, and must be insensitive to aggressive water. In order to maintain the definition, such as alignment, of the waterstops in relation to the old concrete when pouring the new concrete or fresh concrete on this, the positionally secure waterstop arrangement is required at least when coating the old concrete with new concrete.

Even with water-impermeable concrete, such as waterproof concrete, it is required to provide a structure that is water-impermeable with concrete with a high water penetration resistance. However, in order to produce such a joint - also in several work steps - with the formation of old and new concrete, construction joints occur which must be sealed with joint tapes, in particular construction joint tapes. Their precise determination, such as alignment, arrangement and durability, at least up to and including the connection of the pouring of the new concrete into the space delimited by the formwork on the old concrete, makes it necessary to reliably determine the waterstop in relation to the local conditions of the old concrete to which fresh concrete is to be added.

The water-impermeable concrete, also called waterproof concrete, is traditionally water-impermeable but essentially permeable to water vapour. The floor slab and the walls are designed as a closed trough, which encloses the structure and reaches at least above a certain design water level according to the specified requirements. Such a construction is called a white tub. Such construction joints that occur during the manufacture of a white tank must also be permanently secured against water pressure and against water seeping through cracks and gaps into the interior of the white tank with the aid of joint tapes, in particular construction joint tapes.

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 preparing watertight concrete structures in several work steps, there is no capillary transport through the components, e.g via joints and construction joints, i.e. independent of the hydrostatic pressure and the layer structure of the components.

Because even with the provision of components, such as with water-impermeable concrete for the provision of water-impermeable structures, DIN regulations, eg EN 1045-2 / EN 206-1 , are to be observed, high demands are placed on the joint tapes and their sealing capacity in the state of the art.

It is therefore also the object of the invention to support the sealing effect of the joint tape - even with increasing loads from pressing water and/or increasing deformation - to align the joint tape to the local requirements on site already when pouring fresh concrete and also to ensure that the joint tape that is aligned in this way is not deviated from its position or even deformed by the grouting stream with fresh concrete.

However, there is no alignment aid in the prior art, let alone a frame that fixes a plate-shaped seal, e.g.

Rather, it can often be observed in the state of the art that when new concrete is poured in, 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 provide an adequate seal due to the deformations occurring during the pouring oppressive water, seeping water and concrete penetrating moisture.

It is therefore the object of the invention to provide an ironing device which offers the possibility of arranging the joint tape exactly according to the local specifications on site, aligning it according to the specifications on site, which offers security that the joint tape neither has its position in relation to the old concrete changes when pouring new or fresh concrete, nor does the joint tape change its shape or alignment during the pouring.

Apart from that, the ironing device or frame to be provided should be easy to handle on site and can also be handled reliably for the inexperienced user.

In addition, the stirrup device to be provided should be dimensionally stable, so that the stirrup device does not deform when it is cast with new concrete.

Likewise, the stirrup device should be designed in such a way that the stirrup device can be coupled to the steel reinforcement in a secure position and thus also in the same place as at least part of it, in order to prevent a change in position of the stirrup device, e.g. when pouring fresh concrete, but also to ensure that the arrangement of the joint tape in to support the reinforced concrete permanently.

The object is solved by the main claim and the secondary claim. The dependent claims relate to preferred configurations and further developments of the invention.

The bracket device comprises a mounting bracket, which comprises the section bracket and two leg arms molded onto the section bracket. The mounting bracket is designed with a part-circular, preferably U-shaped, or V-shaped section bracket in plan view of the same. The mounting bracket is advantageously made of an elastic material, eg a plastic-like material and/or a metal material. In one embodiment, the bracket device is rigid, that is to say immovable--for example without pivotable leg arms or section brackets--by being manufactured with a metallic material such as steel, iron, aluminum and/or alloys thereof; In another embodiment, the strap means has pivotable and recoverable leg arms or section straps by fabricating them 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 can be smaller than the distance between the opposite 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 the same that are able to have the recorded seal in the recording position.

In the context of the invention, a part-circular mounting bracket is also understood to mean a mounting bracket with two leg arms which are connected to one another, e.g. by a curved section bracket, such as a U-shaped, V-shaped bracket or a section bracket bent at an angle.

In the sense of the invention, the starting position or rest position of the bracket device or the assembly bracket is also understood to mean the assembly bracket with leg arms and/or section brackets and/or the arms in an unloaded state.

In the context of the invention, the reception position of the bracket device or the mounting bracket is also understood to mean the reception of the joint tape in the interior space delimited by the rigid mounting bracket; applying 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 is applied with force against the leg arms and/or the section bracket of the mounting bracket due to its elasticity and resilience, and the remaining of the joint tape in the leg arms and section bracket limited interior space, largely between the pivot arms take place in the holding position for permanent fixing of the arrangement and alignment of the joint tape in the interior space of the mounting bracket. Although the holding position within the meaning of the invention can also be seen or understood as a component of the receiving position, since the joint tape is or is received in the interior in the receiving position, the distinction between the receiving position and the holding position simplifies the principle of the invention because in In the holding position, essentially the force-loaded attachment of the leg arms and/or the section bracket, etc., and thus the permanent non-positive, frictional and/or form-fitting fixing of the joint tape in the mounting bracket take place.

For the purposes of the invention, the receiving position of the bracket device or the assembly bracket is also understood to mean the elastic assembly bracket with its elastic leg arms and/or its elastic section bracket with the spread of its leg arms and/or the section bracket to increase the distance between the leg arms and to accommodate the joint tape; as a result of the back-spreading of the same in the direction of the joint tape with the attachment of the pivot arms and/or the section bracket against the joint tape in the mounting bracket and the joint tape remaining in the interior space between the pivot arms delimited by the leg arms and section bracket in the holding position. Although the holding position within the meaning of the invention can also be seen or understood as a component of the receiving position, since the joint tape is or is received in the interior in the receiving position, the distinction between the receiving position and the holding position simplifies the principle of the invention, since in In the holding position, essentially the force-loaded application of the leg arms and/or the sectional bracket, etc., and thus the permanent non-positive, frictional and/or form-fit fixing of the joint tape in the mounting bracket take place.

For the purposes of the invention, the receiving position of the stirrup device is also understood to mean the insertion of the reinforcement into 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 for a permanent fixing of the reinforcement in the interior can be made possible.

In the context of the invention, the receiving position of the stirrup device is also understood to mean the elastic arms with the same being spread open for receiving the reinforcement and arranging the steel reinforcement in the interior delimited by the arms; the backspreading of the same in the direction of the reinforcement with the attachment of the arms against the reinforcement and remaining of the reinforcement in the interior delimited by arms take place in the holding position. Although the holding position within the meaning of the invention can also be seen or understood as a component of the receiving position, since the reinforcement is or is received in the interior in the receiving position, the distinction between the receiving position and the holding position simplifies the principle of the invention, since in the holding position essentially the force-loaded application of the arms and thus the permanent non-positive frictional and or form-fitting definition of the reinforcement in the mounting bracket take place.

In the context of the invention, prestressing is also understood to mean the force-loaded attachment of the leg arms against the seal as a result of the restoring force of the elastic, such as spring-elastic, leg arms, which is directed towards the seal, like the joint tape, in the receiving position or holding position. In the context of the invention, prestressing is also the force-loaded application of one or both arms against the reinforcement as a result of the restoring force of the elastic, such as spring-elastic, trained arms, which is directed towards the reinforcement, such as steel reinforcement, in the receiving position or holding position.

For the purposes of the invention, spreading the leg arms apart is also understood to mean bending open the section bracket. The easy-to-handle ironing device according to the invention comprises the easy-to-install ironing device according to the invention with the seal accommodated in the interior of the mounting bracket of the ironing device, such as the joint tape, and/or with the reinforcement accommodated in the interior of at least one arm of the ironing device, such as the steel reinforcement. In one embodiment of the easy-to-install ironing device according to the invention, the ironing device is designed in one piece; For the purposes of the invention, one-piece is also understood to mean that this can be produced, eg extruded, with the leg arms, the section bracket and with at least one arm as a whole, ie in one piece.

The interior of the mounting bracket, which is delimited by the section bracket and the two leg arms, accommodates a joint tape running in the form of a strand, e.g. as a plate-shaped seal, the central longitudinal axis of which can also 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 force, also known as pretension.

Within the meaning of the invention, bridging of joints between structures, between their parts and/or within them is also understood to mean spanning or overlapping of the joints between adjacent building parts, 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 building parts, so that the neighboring building parts can be connected to each other, e.g. to close or limit the joints. Within the meaning of the invention, a joint is also understood to mean the intermediate space between two components, such as tunnel segments.

In order to make it easier to insert the joint tape into the mounting bracket and to prevent it from jamming over a large area with the limb arms, in a special embodiment of the bracket device according to the invention, opposite elevations, such as spikes or pegs, are formed on the inner sides of the limb arms, so that the limb arms are in the receiving position with their thorns against the joint tape. The thorns as spacers make it easier to align the joint tape between the leg arms in the receiving position and the positional security of the joint tape relative to the leg arms and fixing of the joint tape in the mounting bracket interior in the holding position is supported; In addition, the spikes applied against the waterstop effectively prevent the waterstop from slipping in the interior space of the stirrup device, which is delimited at least by the leg arms and the section stirrup, when pouring liquid concrete in the holding position. Likewise, thorns can be formed on the inside of the section bracket, which support the punctiform attachment of the thorns against the joint tape. As thorns are intrinsically suitable. e.g. cylindrical, conical or tapered pegs.

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 to 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 maintenance of a widening and thus greater spacing of the leg arms from one another, which has taken place through the receiving of the joint tape.

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, although it is suitable for receiving the joint tape. The mounting bracket in a rigid design is also suitable for holding the waterstop, since the waterstop, due to its elasticity due to its manufacture with an elastic, e.g , Limited interior space as a result of collapsing or pressing in the joint tape, such as can be introduced transversely to its center longitudinal axis in the leg arms adjacent sections of the joint tape. The application of the joint tape as a result of pressing in the sections of the joint tape, e.g. those adjacent to the leg arms, so that the joint tape is applied with force against the leg arms and/or the section bracket of the mounting bracket due to its elasticity and resilience, and the remaining of the joint tape in the leg arms and section bracket limited interior space, largely between the pivot arms take place in the holding position for permanent fixing of the arrangement and alignment of the joint tape in the interior space of the rigid mounting bracket.

In another embodiment of the mounting bracket, it can be designed to be elastic using an elastic material. Thus, the leg arms and/or the section bracket can be made with an elastic material. In one embodiment of the mounting bracket with an elastic, e.g. into the recording 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 known as restoring force, spring force or straightening force, strives to restore the original position and alignment of the leg arms when they are at rest. As a result of the transition from the rest position to the receiving position and the mounting bracket remaining in the receiving position, the leg arms are spaced apart by the spreading 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 can. After the joint tape has been inserted into the interior or passed through it, the leg arms largely return to their original position in the holding position as a result of the restoring force, which corresponds approximately to the rest position or the leg arms approaching each other. The restoring force, which can also be referred to as spring force, ensures that the leg arms and/or the section bracket or part thereof are applied with force, due to its part-circular design, against the joint tape in the holding position, so that the positional security of the joint tape in the clip device according to the invention is also maintained when pouring or pouring liquid concrete onto the same, in the area in which the stirrup device and the joint tape are arranged. Depending on the use of an elastic material, the clip device according to the invention can advantageously generate a different degree of restoring force or spring force. Precisely through the use of ironing devices according to the invention, possibly of different elastic materials, the ironing devices according to the invention can also be kept ready with different restoring forces that the user desires on site.

The ironing device according to the invention additionally comprises an arm, preferably two arms, which merge with their first, mutually adjacent ends into the other ends of the leg arms lying opposite the one ends; the median longitudinal axis of the interior delimited by one or both arms, preferably helical, is advantageously oriented transversely to the leg arms. In a special embodiment of the easily installable bracket device according to the invention, the helical arms can be produced with helically wound round, square and/or rectangular rods. The first ends of the helical arms facing the leg arms are advantageously straight, also extending along the central longitudinal axis of the interior delimited by the helical arms, preferably merging into the other ends of the leg arms, for example at right angles . Advantageously, the central longitudinal axis of the interior is aligned transversely to at least one leg arm. In at least one embodiment of the easy-to-install ironing device according to the invention, the two central longitudinal axes of the helical arms match, so that they form a uniform, like common, central longitudinal axis that can be aligned transversely to the leg arms.

The arms can be adapted to the outer contour, such as the outer shape, of the steel reinforcement; e.g., the arms are helically formed comprising coils of the stirrup means are formed such that the circumferences of the coils with radii of curvature may conform to the diametric radii of curvature of the steel reinforcement to be accommodated in the arms. Within the meaning of the invention, a coil is also understood to mean a fully circular coil or a coil describing a full circle or a bend describing a full circle when looking at the inner space delimited by the arms with the center longitudinal axis as the center point. Within the meaning of the invention, the number or number of turns is also understood to mean the number of turns describing a full circle or the bends describing a full circle.

In one configuration of the arm, it can have a different number of turns, for example two to five full-circle turns with a number of turns of 2 to 5, preferably two to three full-circle turns with a number of turns of 2 to 3, even more preferably a number of turns of 1, 2, 3 or 4. Also, the helical formation of the arm can be uniform or have different helix angles.

The inside diameter, also called coil opening or diameter, of the interior delimited by the helical arms is in the configuration of elastic helical Arms in the rest position are understandably smaller than those in the receiving position in the case of the received part of a steel reinforcement inside the same. Within the meaning of the invention, the winding diameter is also understood to mean the clear width of the interior delimited by an arm when the interior space is viewed from above.

In a further embodiment of the easy-to-install ironing 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 unfolding, includes a pitch angle α that is less than 90°, preferably between 10 ° to 45 ^° , more preferably 10° to 25 ^° or 15 ^° to 35 ^° or 15 ^° to 30°, advantageously 10 ^° , 15 ^° , 20 ^° or 25 ^° ; For the purposes of the invention, the helical surface is also understood to mean the surface that is created by screwing or winding, to which another straight line can be attached to form the angle by means of the straight lines set transversely to the central longitudinal axis of the helical arms.

The clear width of the inside or the coil diameter, including the radii of the same, also depends on the requirements on site and the outer diameter of the steel reinforcement to be accommodated, so that depending on the requirements for 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 circumstances can be adjusted on site.

In another embodiment of the ironing device according to the invention, the arms are rigid, so that the arms cannot be pulled apart or compressed or their coils cannot be pulled apart or compressed and the coil diameters also remain essentially unchanged. This does not rule out the possibility of a certain amount of play, such as movement play, between the arm and the reinforcement even when using rigid materials.

Also, the arms may be made with an elastic material so that the arms are expandable or compressible, e.g., along their central longitudinal axis; the winding openings or the clear width of the interior, which is delimited by the arms, is consequently advantageously adaptable 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 expanding the clear width by inserting a rod-shaped tubular steel reinforcement, a counterforce or expansion force that exceeds the restoring force of the arms is also generated during the transition from the rest position to the receiving position, so that in the receiving or holding position the arms are subjected to force as a result of the restoring force or spring force against the surface of the steel reinforcement and remain open in a secure position as a result of the prestress generated by the restoring force.

The bracket device according to the invention, e.g. with its leg arms, section brackets and/or arms, can be made with an elastic plastic-like material which contains at least one representative of the TPE, PVC, NBR, PE, PP, SBR, Group comprising EPDM, CR and NR compounds and derivatives thereof.

TPE can include thermoelastic or thermoplastic elastomers, PVC polyvinyl chloride, 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 derivatives thereof are understood. Both plastics that swell or swell in liquid, such as in water, and plastics that swell or swell in liquid, such as water, can be used to produce the leg arms, the section bracket and/or at least one arm of the bracket device.

In a particular embodiment, the elastic 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 ironing device according to the invention with concrete or fresh concrete after casting with the same and the positional security of the seal in the same also permanently to increase. In the context of the invention, thermoplastic elastomers, such as TPE, are understood as meaning polymers or thermoplastic rubbers which can have a combination of the performance properties of elastomers and the processing properties of thermoplastics. This can be achieved if, for example, in the macromolecules of the corresponding plastics, soft and elastic segments with high extensibility and low glass transition temperature (T _g ) and hard, crystallizable segments with low extensibility, high T _g and a tendency to form associations, such as physical crosslinking, present. The soft and hard segments are preferably mutually incompatible and present as individual phases. Thermoplastic elastomers are also suitable if they are thermolabile, reversibly cleavable crosslinking sites, ie are of a physical but also chemical nature. Conventional thermoplastic elastomers are suitable, such as the styrene-type thermoplastic elastomers. These can have butadiene or isoprene or ethylenebutylene as soft polymer segments and styrene compounds, such as SBS, SIS, or SEBS, as hard polymer segments.

For example, classified into TPE classes, thermoplastic elastomers can also be used, such as those of the styrene type comprising soft polymer segments with crosslinked EPDM or crosslinked NR, or ethylene vinyl acetate or crosslinked NBR, and as hard polymer segments those with propylene or those comprising vinylidene chloride. These are known to those skilled in the art as EPDM / PP or NR / PP or EVA / PVDC or NBR / PP. Conventional thermoplastic elastomers are suitable, such as the thermoplastic elastomers of the polyurethane type, which also have soft polymer segments with ester glycols and hard polymer segments with isocyanate chain extenders or the H bonds. Also suitable as thermoplastic elastomers are those of the polyetherester type which have alkylene glycol as the soft polymer segments and alkylene terephthalate as the hard polymer segments. Also suitable as thermoplastic elastomers are those of the polyetheramide type which have ether diols as soft polymer segments and amides as hard polymer segments. The thermoplastic elastomers can swell in the presence of liquids such as water.

TPE and thermoplastic elastomers can also be used, for example, TPO, such as oliefin-based thermoplastic elastomers, 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 fluo rubber, TP-Q, such as thermoplastic silicone rubber, TPU, such as thermoplastic polyurethanes, CPE, CPA as copolymeric polyetherester, PEBA, such as polyether block amides and/or MPR, such as melt-processible rubber, etc.

In addition, the elastic, plastic-like material can also include proportions of water-absorbing compounds that swell as a result, for example crosslinked 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 crosslinker, such polymer molecules can be crosslinked with one another by chemical bridge bonds , whereby these bridges can be insoluble in water, but water molecules can attach themselves to their polar groups. Due to the additional use of polar polymer compounds in the thermoplastic elastomers, the swelling of the thermoplastic elastomers is increasingly supported.

For the purposes of the invention, a seal is also understood to mean an elastic band which can extend in the form of a strand and/or in the form of a plate along its central longitudinal axis. In the context of the invention, joint tape is also understood to be an expansion joint tape whose sealing strips, webs and strip-shaped ribs are or can be firmly embedded in building parts as so-called sealing lips as a result of material casting, such as concrete casting.

The following and previous explanations and special configurations of the ironing device according to the invention relate to this in the rest position and/or during or after receiving the joint tape before or after installation of the same using new or fresh concrete, such as in a concrete-like mass such as concrete. Within the meaning of the invention, new concrete, fresh concrete or concrete or a concrete-like mass can also be understood to mean a mixture or a mixture with cement as a binder, gravel sand as an aggregate, water and, if necessary, other aggregates and/or aggregates, depending on the requirement for the provision of buildings and or parts thereof.

Within the meaning of the invention, joint tape can also be understood as a construction joint tape. In the context of the invention, joint tape is also understood to mean a seal as a joint tape whose sealing strips with/or without ribs or projections as a result of material casting, such as casting of concrete-like mass, e.g. concrete casting, are firmly embedded in building parts; Within the meaning of the invention, construction joint tape is also understood to mean a joint tape which, in contrast to the expansion joint tape, can also contain at least inelastic material. The construction joint tape is used if, for example, components cannot be manufactured in one concreting step. The construction joint tape can run with its central longitudinal axis horizontally or vertically in the component and can be installed in half in the first or in the second concreting step section.

The joint tape has, for example, two sealing strips which can run in the form of a strand along a central longitudinal axis of the joint tape. The following and previous statements and special configurations of the joint tape can be used in the relaxed state, also known as the resting state, e.g. before the end of the joint tape is pushed into the ironing device according to the invention or in its interior, before installation or grouting with a concrete-like mass, such as concrete, or the like. The The following and previous statements and special configurations of the joint tape can also relate to this after the end of the joint tape has been pushed into the ironing device or in its interior without or after concrete filling.

The sealing strips are polygonal in cross section. For the purposes 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 area Be understood, fusion of both, in the transition area, extrusion to produce the one-piece joint tape or the like. For the purposes of the invention, a corner area is also understood to mean an apex angle area, which can be the apex or the point of intersection of the two straight lines delimiting the corner area in plan view or in cross section; the apex angle area has a common apex, which can be on or in the web, into which the corner area can merge,. can be arranged. The straight lines can usually intersect at this apex or point of intersection, with the long sides, e.g. of the corner area or areas, of the sealing strips being able to lie on the straight lines. The polygons as triangles can be designed as equilateral, isosceles, right-angled, acute-angled, or obtuse-angled; the sealing strips can also be designed as different 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.

The joint tape can be extruded with the sealing strips, the webs, the strip-shaped ribs, or these parts, such as webs, can be coextruded on the sealing strip. The joint tape can also be extruded with a plastic-like material, such as a material connection, or co-extruded with various plastic-like materials, with certain parts, such as projections that can be used as sealing lips or ribs, being co-extruded or extruded onto the sealing strip. The above-mentioned plastic-like material which can already be used for the production of the ironing device according to the invention, for example thermoplastic elastomers or other plastic-like materials which swell or swell in the presence of liquid, can be suitable as the plastic-like material. These can be as malleable or recoverable at a predetermined temperature.

For the purposes of the invention, joint tapes are also understood to be internal and/or external, or construction joint tapes or joint sealing tapes, e.g. to close a joint flush, which can be internal or external. In the context of the invention, 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 attached and freshly poured. 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 in cross section in the relaxed state are at least partially part-circular in cross section.

The long sides of the two, e.g. one and the other, sealing strips are aligned in an X-shape in cross section and the two opposite side strips molded onto the long sides of, e.g. the other, sealing strip are aligned in a cross shape with the same, with e.g Center-longitudinal axis aligned, e.g. equally spaced from the longitudinal sides, center-transverse axis-related sidebar can be congruent to the other sidebar. For the purposes of the invention, connection is also understood to mean, for example, gluing, fusing, providing in one piece, etc. Long side of a sealing strip is also understood within the meaning of the invention to mean the extension of a side or leg of the sealing strip from its outside to its corner area or up to to the transition area or to the mean distance between the two corner areas. Within the meaning of the invention, the outside of the sealing strip is also understood to mean, for example, the side of the same that is opposite the corner region of the sealing strip, such as the base or hypotenuse.

The two sealing strips are, for example, aligned with one another in such a way that the corner regions of the sealing strips which are adjacent to one another have the common so-called apex angle region. 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. merging directly into one another or merging into a common web. The sealing strips, which are also 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 configuration of the Joint tape ends blunt and can merge from both sides of the sealing strips into the common web.

This web also runs in the form of a strand like the sealing strips along the central longitudinal axis. In cross-section, the apex angles of the apex angle range may each be less than 90 ^° , preferably ^{10-90 °} , more preferably ^{20-50 °} , more preferably ^{40-45 °} or ^{60-50 °} , most preferably ¹⁰ , ²⁰ , 3 ⁰ , 4 ⁰ , 5 ⁰ , 6 ⁰ , 7 ⁰ , or 8 ⁰ , or 10 ⁰ .

The particular advantages of the arrangement of the sealing strips with their mutually aligned and interconnected wedge tips are also due to the special fact that the sealing strips are firmly embedded in parts of the building, such as reinforced concrete walls, as a result of material grouting, such as grouting with a concrete-like mass, e.g. concrete grouting hook into the concrete, so that when the expansion joints of the two parts of the building drift apart, the joint tape cannot be observed to come loose from the expansion joint. In a special embodiment of the joint tape, the outer sides of the sealing strips lying opposite the corner regions 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 of the corner areas or of the apex angle areas can be equally spaced, so that the tensile forces acting on them can act more evenly. The joint tape is particularly suitable if, in cross-section, the distance between the two web sides, which can run parallel to one another, is less than the width of the outside of the sealing strip, which corresponds to the distance between the longitudinal sides of a sealing strip in relation to the corner area. Within the meaning of the invention, the width of the outer sides is also understood to mean the distance between the two longitudinal sides of a sealing strip in the region of the sealing strips opposite the apex angle region. The width of the joint tape can also be understood within the meaning of the invention as the sum of the length of one web side and the two distances, also known as the length of the long side, between the outer sides and the corner areas of the sealing strips.

In the context of the invention, the length of the longitudinal side of the sealing strip is also understood to be the distance between the outside of the sealing strip and the transition of this sealing strip to the web. Within the meaning of the invention, the term web is also understood to mean the transition region, which is formed with the outer sides preferably aligned parallel to one another, between the corner regions of one sealing strip and the other sealing strip or connects the two to one another; web can also be understood to mean a bar. In addition, the head regions of the sealing strips opposite the corner regions and/or the head regions of the side strips and/or ribs opposite the sealing strip can be drawn in, forming interrupted or continuously extending channels along the central longitudinal axis, which swells or swells in the presence of water record n.

The swelling tapes can also include proportions of water-absorbing compounds that swell as a result, for example crosslinked 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 crosslinker, such polymer molecules can be crosslinked with one another by chemical bridge bonds, with these Although bridges can be water-insoluble, water molecules can attach to their polar groups. Due to the additional use of polar polymer compounds in the thermoplastic elastomers, the swelling of the thermoplastic elastomers is increasingly supported. Suitable materials for the swelling tapes are conventional materials that swell in the presence of liquids, such as water-swellable plastics or water-swellable rot-free or rot-poor natural materials, other swellable coatings; materials that are rot-resistant, non-aging, resistant to UV rays, ozone, atmospheric oxygen, bitumen-resistant, oil-resistant, heat-resistant, petrol-resistant and/or waterproof are particularly suitable, for example organic, natural, organically modified natural substances, organic, fully synthetic and/or inorganic swelling or thickener. Swelling agents are also understood as meaning conventional thickeners, which are preferably organic high-molecular substances which are able to absorb water and moisture effectively and swell in the process. The sealing is visibly supported by the swelling. The swelling tapes can be impregnated with such swelling agents. It is also possible to use natural and/or synthetic fibers that are able to absorb water and moisture due to their hydrophilic surface. Swellable tapes can also be used that are puffed up in such a way that they can attract water and moisture and swell. As swelling agents can be used organic natural, organically modified swelling agents such as carboxymethyl cellulose, cellulose ethers, hydroxyethyl cellulose, hydroxypropyl cellulose and/or derivatives thereof, organic fully synthetic swelling agents, for example polyacrylic or polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides and/or derivatives thereof; Inorganic thickeners are also suitable, for example polysilicic acids, clay minerals such as zeolites, silicic acids and/or their derivatives.

In a particular embodiment of the method according to the invention, in the case of forming spikes on the insides of the leg arms and/or spacer brackets, the spikes are subjected to a force, such as spring-elastic, against the longitudinal sides and web sides of the joint tape. In addition, it has been shown that spikes, which are formed on the inner sides, help to facilitate the adjustment and centering of the joint tape in the interior space delimited by the leg arms and section brackets.

Slipping or movement of the joint tape is not only prevented along the leg arms on both sides, by the section bracket on the upper side by the section bracket connecting the two leg arms, but also by the part of the steel reinforcement inserted into the helical arms on the underside opposite the section bracket. Due to the all-round limitation and avoidance of movements of the joint tape in the ironing device according to the invention, the positional security and thus the locational fidelity of the joint tape is reliably connected in relation to the steel reinforcement and in relation to the old concrete when grouting with fresh concrete.

It has been shown that the ironing 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 ironing device centered and precisely aligned with the steel reinforcement using the ironing device according to the invention.

The method according to the invention and the use according to the invention of the ironing device for aligning a joint tape is carried out in such a way that the helical arms receive a cylindrical part of a steel reinforcement or such is inserted through the interior of the helical arms delimited by the helical arms or passed through them beyond . In a further embodiment, the helical arms can also be attached under prestress against the outside of the cylindrical part of the steel reinforcement in order to increase the positional security 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.

The joint tape is pushed into the interior delimited by the leg arms and spacer brackets and due to the prestressing of the leg arms, the leg arms are subjected to force such as spring force to the longitudinal sides and/or web sides of the joint tape. In a particular embodiment of the method according to the invention, in the case of forming spikes on the insides of the leg arms and/or spacer brackets, the spikes are spring-elastic against the longitudinal sides and web sides of the joint tape. In addition, it has been shown that spikes, which are formed on the inner sides, facilitate the adjustment and centering of the joint tape in the interior space delimited by the leg arms and section brackets.

In one embodiment of the easily installable bracket device 1, the rigid, as if immovable, mounting bracket 2 is made of an inelastic, preferably plastic-like and/or metal material, and the joint tape 20 is attached to the inner sides 3c of at least the leg arms 3 as a result of attachment the portions thereof adjacent to the leg arms and/or the steel reinforcement 28 are provided for abutting or seating against the inner sides 5d of the arms 5 in the holding position; In one embodiment of the easily installable bracket device, the deformable mounting bracket 2 is made of an elastic, preferably plastic and/or metal, material and is prestressed with the inner sides 3c of at least its leg arms 3 for attachment against the joint tape 20 by means of a spring or restoring force and/or with the insides 5d of the arms 5 against the steel reinforcement 28 in the holding position.

The easy-to-install bracket device 1 according to the invention is suitable for fixing a strip-shaped, such as plate-shaped, seal running along the central longitudinal axis X, here the joint tape 20, with a U-shaped mounting bracket 2 in the relaxed state or in the rest position, which is used to accommodate the joint tape 20 is provided in a receiving position under pretension, which comprises a section bracket 4 and two leg arms 3; one end 3a of the leg arms 3 merges into the section bracket 4 and two arms 5 merge into the other ends 3b of the leg arms 3 with their first ends 5a adjacent to one another. 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 designed in the form of a screw; on the inner sides 3b of the leg arms 3 thorns 6 formed as a pointed pin, which are formed for the selective attachment of the joint tape 20 against the thorns 6 and centering the same

The one-piece ironing device 1 according to the invention is made with an elastic 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 one another is less than in the receiving position, in which these are at least partially spread open and then applied against the joint tape 20 with a force applied; a degree of application of force remains, since pivoting the leg arms 3 back into the original rest position, such as in the relaxed state with the original distance A, cannot be possible as a result of the thickness of the joint tape 20 exceeding the original distance. For the purposes of the invention, prestressing is also understood to mean the restoring force or spring force of the mounting bracket 2 generated as a result of the spreading apart along a pivoting direction Z, e.g the interior 30 of the mounting bracket 2 recorded joint tape 20 are applied force applied.

The two helical arms 5 are made with helically wound round rods and have, e.g. arms 5 protruding, straight along the central longitudinal axis LA of the interior delimited by the helical arms 5 extending adjacent ends 5a, 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 may have two to five turns, preferably two, three or four.

Since the arms 5 are made of an elastic material, they act like a helical spring, for example, in such a way that if part of the steel reinforcement 28 is accommodated in the interior 5c of the arms 5, the screw length SL running parallel to the central longitudinal axis LA of the arms 5 Arms 5 are shortened, the clear width or the inner diameter AL, also called winding diameter or opening, of the interior delimited by the arms 5 increases. Within the meaning of the invention, winding diameter is also Understood, the clear width of the interior 5c delimited by an arm when viewed from above in the direction of the arrow (see arrow, 1 ). For the purposes of the invention, the number or number of turns is also understood to mean the number of turns describing a full circle or the bends describing a full circle. In exemplary embodiments, the arms 5 have two to five full-circle turns with a number of turns of 2 to 5, preferably two to three full-circle turns with a number of turns of 2 to 3, even more preferably a number of turns of 1, 2, 3 or 4.

The pitch angle α delimited by a straight line 11 set transversely to the central longitudinal axis LA of the helical arms 5 and the helical surface 12 as part of the helical line according to the development or by the straight line 11a applied to the helical surface 12 is less than 90 ^° , preferably between 10 ^° and 45° ⁰ , more preferably 15 ⁰ to 35 ⁰ , advantageously 15 ⁰ , 20 ⁰ , or 25 ⁰ . The straight line 11 set transversely to the central longitudinal axis LA of the helical arms 5 and facing away from the observer in a plan view of the arm 5 in this, behind the in 3 The winding part of the same extending center longitudinal axis 12a that is arranged along the center longitudinal axis LA shown is less than 90 ^° , preferably between 10 ^° and 45 ^° , even more preferably 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 a free end can be aligned along the straight line 11.

Since the leg arms 3 and/or the section bracket 4 are made of an elastic, preferably plastic-like and/or metal material, at least the leg arms 3 lie elastically, as if subjected to a force, in the receiving position on the joint tape 20 accommodated in the interior of the mounting bracket 2. In the rest position, ie without receiving the joint tape 20 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 part of the same, the mounting bracket 2 is subjected to a counterforce that exceeds the restoring force generated by the mounting bracket due to spreading, also called force or spring force, in order to prevent the insertion of the joint tape 20 in the leg arms 3 and the section bracket 4 to allow limited interior space of the mounting bracket 2 in a light manner, the leg arms 3 being held at a distance, for example, by the joint tape and its longitudinal sides 22 or the 22 of the sealing strips 21 . In the holding position, the leg arms 3 are pivoted back in the direction of the recorded joint tape, so that they are subjected to a force -prestressed- engage in the joint tape 20 and the counterforce as a result of pivoting back in the opposite direction to the pivoting direction Z decreases slightly. Due to the holding position of the mounting bracket 2 of the bracket device according to the invention, the joint tape 2ß is fixed in relation to the same orientation and arrangement.

Determining the waterstop 20 with regard to alignment is also understood within the meaning of the invention that the waterstop 20, without undergoing a change in shape, apart from pressure points in the same caused by swivel arms 3 and/or section brackets 4, if necessary steel reinforcement 28, with regard to of the steel reinforcement 28, for example, is coupled to it perpendicularly or at a predetermined angle using the stirrup device according to the invention, without the waterstop 20 or parts thereof being kinked, but rather the waterstop -quasi in the relaxed state- in the mounting bracket 2 of the stirrup device as on both sides of the Leg arms 3 and how multisided or all sides of the leg arms 3 and the section bracket 4 and / or the steel reinforcement 28 is held. Determination with regard to the arrangement of the joint tape 20 is also understood within the meaning of the invention that the joint tape 20 does not experience any change in its shape, i.e. no crushing or stretching occurs - which would impair the tightness of the same -, i.e. also approximately in the relaxed state in the mounting bracket 2 is held.

It has been shown that precisely through the application of the leg arms 3 force is applied, such as spring force, due to the elastic design of the same and/or the section bracket 4, the spikes formed on the inside of the leg arms 3 and/or on the inside of the section bracket 4 the joint tape 20 both at points and are also able to pinpoint precisely as well as when grouting with fresh or new concrete the on-site desired fixing of the joint tape 20 is maintained in contrast to the prior art.

The helical arms 5 can also be made of an elastic material, such as plastic and/or metal, so that in the rest position, i.e. without receiving part of the steel reinforcement 28 in the interior delimited by the helical arms, they have a smaller inner diameter AL or have clear width and as a result of the introduction of a part of the steel reinforcement 28, for example a cylindrical one, into the interior along the middle Longitudinal axis LA of the inside of the helical arms, the length of the helical arms 5 is able to shorten and the inner sides of the arms 5 delimiting the inside are elastically force-loaded against the part of the steel reinforcement 28, such as spring force, are attached. By introducing the part of the steel reinforcement 28 into the interior, a counterforce is also generated as a result of the expansion of the interior 5c, which is able to exceed and counteract the spring force of the helical arms 5, so that as a result of the force, form and/or frictional connection between the helical Arms 5 on the one hand and the part of the steel reinforcement 28 on the other hand, the swiveling of the ironing device according to the invention around the part of the steel reinforcement 28 accommodated in the helical arms can be restricted and even prevented, advantageously in order to also 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 fix the orientation of the stirrup device 1 according to the invention (not shown).

The ironing device according to the invention is also characterized in that the ironing device according to the invention can enclose the plate-like, longitudinally extending seal, such as joint tape 20 . Mandrel-like, e.g. Since the spikes 6 protruding from or protruding from the inside 36 of the leg arms 3 as spacers can prevent the planar application of the joint tape 20 against the inside 36 of the leg arms 3, the spikes 6 may reach deep into the joint tape 20 as a result of their being acted upon by the restoring force and support the positional security of the joint tape 20 in the interior 30 of the mounting bracket 2. This prevents a water-carrying channel from being able to form between the bracket device according to the invention and the seal.

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

The helical arms 5 are attached to the steel reinforcement 28, such as reinforcing steel, in a non-positive, positive and/or frictional manner.

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

At the same time, the helical arms ensure high positional stability when attached to small rod diameters.

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

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

Due to the axial shortening of the helical arms 5 as a result of the insertion of part of a steel reinforcement 28, for example reinforcing steel, at least part of the helical arms 5 rests against the part of the steel reinforcement under elastic force.

The inner diameter AL of the helical arms 5 in cross section or the clear width AL or the winding diameter of the helical arms in cross section increases due to the restoring force generated as a result of the introduction of part of the steel reinforcement 28, so that due to the force-loaded frictional and/or non-positive attachment of the helical arms 5 against the received m part of the steel reinforcement 28 also to fix the waterstop 20 in the receiving position on the old concrete, for example horizontally along the central longitudinal axis X of the waterstop 20 running and/or to the surface of the old concrete.

The one-piece joint tape 20 comprises an elastic, plastic-like material which extends along its central longitudinal axis X and comprises two sealing strips 21 running in the form of a strand along the central longitudinal axis X, each sealing strip 21 having two longitudinal sides 22 tapering to one another in cross-section to form a one is designed against a steel reinforcement 28 attachable outside 20a of the sealing strip 21 opposite corner area 23; the corner areas 23 of the sealing strips 21 are connected to one another in a transition area 25, such as fused, glued or extruded, with the transition area 25 being designed 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 . 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 are at least one, preferably two and more strip-shaped, preferably along the central longitudinal axis X and parallel to one another. For example, continuous or interrupted running ribs 29 formed as sealing lips; 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, for example thermoplastic elastomers, and/or in the web 24 and/or in at least one sealing strip 21 a hollow space running along the central longitudinal axis X is formed. The sealing strips 21 are designed in cross section as isosceles, preferably acute-angled or equilateral triangles, with a marking strip being arranged at least on one web side 26 to identify a predetermined requirement or instruction, preferably an embedment depth in the concrete.

An exemplary embodiment relates to the method according to the invention for aligning a joint tape 20 with an ironing device

The advantages of the ironing device, method and use according to the invention are also
supporting the sealing effect of the joint tape - even with increasing loads from pressing water
no deformation of the joint tape by the grout jet with fresh concrete,
the easy determination, such as alignment and arrangement of the plate-like seal, such as the joint tape on site,
the reliable alignment aid for casting without losing the location of the joint tape
the easy handling on site, even for the inexperienced user,
the retention of dimensional stability when grouting with new concrete,
the positionally secure and thus also location-true coupling to reinforcement with permanent determination in relation to the alignment and arrangement of the joint tape during and after pouring with new concrete
and
the applicability for any kind of waterstops.
