The invention relates to a method for sealing a parting line between concrete wall elements to be filled, a device for sealing a parting line to be filled between concrete wall elements, a joint anchor of a device for sealing a parting line between concrete wall elements to be filled and a parting line between concrete wall elements which is filled with a joint filling material.

From the DE 10 2008 013 206 A1 For example, there has been known a method for joining precast concrete parts, in which a joint seal is made with a sealing mortar using an additional tool. This tool with two brush blades allows a temporary sealing of the parting line when filling the parting line with the sealing mortar, by the two scraper sheets are tracked during the feeding of the sealing mortar along the parting line. This method is complicated by the application of the separate sealing mortar and the required curing time of this sealing mortar and a significant disadvantage is that the carrying capacity of this sealant mortar can not be calculated sufficiently reliable.

It is also known to inject separating joints with mounting foam and thus close, so that during the subsequent concreting the concrete sludge can not escape through the parting line. After hardening of the concrete, the mounting foam must be laboriously scraped out and the surface of the filled parting line plastered evenly.

The object of the invention is to provide an aforementioned method which simplifies the production of a joint filling, as well as to provide a device mentioned above, which allows the production of a filled parting line with simple means in a cost effective manner. Furthermore, an initially mentioned joint anchor should be provided with improved properties and an initially mentioned parting line should be created, which can be produced with less effort.

The object is achieved by a method having the features of claim 1, by a device having the features of claim 5, by a joint anchor with the features of claim 10 and by a parting line having the features of claim 14.

Advantageous embodiments of the invention are specified in the dependent claims.

According to the method of the invention, a sealing strip with at least one associated joint anchor is first brought into a position sealing the parting line to the concrete wall elements delimiting the parting line, wherein the joint anchor is brought into a mounting position which penetrates the parting line. Then, the sealing strip is biased by the joint anchor, which is brought with a head portion in at least one of the concrete wall elements cross-engaging or engaging behind fastening position against the concrete wall elements. Subsequently, the parting line is filled with Fugenfüllmaterial and after curing of Fugenfüllmaterials one of the sealing strip associated base portion of the joint anchor is separated from the Fugenfüllmaterial held head portion and the sealing strip and the separated base portion are removed from the parting line. The head section held by the joint filling material remains in the joint filling material.

A sealing strip for the method according to the invention or the device according to the invention is an elongate flat or profiled component which has one or more surfaces, which may have different shapes, wherein at least one of the surfaces covers a parting line or even extends into a parting line and this parting line between Cover two concrete wall elements largely tight. The required tightness depends on the joint filling material used and on the surface quality of the filled parting line to be provided. The sealing strip is a sufficiently rigid component made of metal, plastic or z. B. is made of a composite material and due to its material properties is often reusable.

A concrete wall element is a component that is used for producing a wall or a ceiling of a building of any kind or even a wall, said joints between two concrete wall elements or between a concrete wall element and an adjacent different type of component that limits the parting line, at least partially a concrete slurry or other liquid, flowable or pasty Fugenfüllmaterial is filled, which then solidifies or hardens and thus remains in the parting line.

The parting line to be filled can be arranged horizontally, vertically or in principle in any spatial orientation.

A joint anchor is a holding and fastening part, which is suitable in any embodiment, to attach the sealing strip on directly or indirectly introduced holding forces on the parting line or the parting line forming and limiting components and releasably secure. The joint anchor is present during assembly, with or after attaching the sealing strip on and positioned in the parting line. Each sealing strip is fastened with at least one joint anchor. Several identical or different joint anchors a sealing strip, which are spaced apart along the sealing strip, can be brought simultaneously or sequentially in their mounting position in which they pass through the parting line.

Each joint anchor is filled with a z. B. referred to as a head portion front portion in an at least one of the concrete wall elements engages behind the fastening position and indirectly indirectly via at least one auxiliary component, which is arranged on the component or concrete wall element, applied and supported, the attachment is in particular form-fitting or frictionally engaged. A positive holding engagement can, for. B. on an edge on one of the sealing strip opposite back or inside of the parting line limiting element or concrete wall element done.

Under the engaging behind at least one of the concrete wall elements is also a definition of the joint anchor or its head portion in the parting line understood, this definition frictionally or z. B. in a groove or on a projection which is formed in one of the parting line facing surface of the component or concrete wall element or on an inserted auxiliary component, can take place.

Depending on the design of the head section or an anchor head of the joint anchor, therefore, an attachment of the joint anchor is made only on one of the components or concrete wall elements or on both components or concrete wall elements.

Subsequently, the parting line is filled with joint filling material. The filling takes place z. B. when pouring hollow or double wall elements, which are placed adjacent to form a parting line adjacent and their cavities is filled in a known manner with Betonschlemme. After curing of the joint filling material, which is formed in particular by the Betonschlemme, a portion of the joint anchor, which is also referred to as a base portion and which is opposite to its head portion, separated from the joint filling material held by the head portion. The base section contains the section of the joint anchor, which is in retaining force engagement with the sealing strip during attachment. Thus, the force acting on the sealing strip clamping force is removed, so that both the base portion of the joint anchor as well as the sealing strip can be removed from the parting line. Only the head portion held by the joint filling material remains in the joint filling material and thus in the parting line, but in a position which is largely invisible from the front side. The sealing strip can now be reused on another parting line with the method according to the invention, with new joint anchors being used.

The handling of the joint anchor is preferably done manually, z. B. via a handle on the head portion or anchor head opposite end or base portion of the joint anchor, positioned over the joint anchor and over which a tensile force can be applied. However, a mechanical actuation of the joint anchor could also be provided by means of a corresponding handling device.

Preferably, the joint anchor is adjusted about its longitudinal axis such that at least one projection or anchor hook of the anchor head engages or engages behind at least one of the concrete wall elements. The anchor hook can thus be inserted into a narrow parting line, wherein the anchor hook extends substantially parallel to the parting wall delimiting wall surfaces, and can then be rotated or pivoted into a locking position and in particular in a transverse position, the holding or locking engagement on a or at both the parting line delimiting components or concrete wall elements allows.

The joint anchor can be fastened or latched directly or indirectly to the sealing strip by means of a holding device, so that the sealing strip is sealingly attached to the concrete wall elements under pretensioning of the parting line. An indirect attachment is z. B. via an additional component which is arranged between the joint anchor and the sealing strip and which transmits the biasing force.

Conveniently, after curing of the joint filling material, the base section of the joint anchor is separated in particular by tensile or bending stress in a region between the holding device or latching device and the anchor head. The separation takes place in particular at such a location, which is substantially flush with the surface of the cured Fugenfüllmaterials.

A device for sealing a parting line to be filled between two concrete wall elements or a concrete wall element and another component thus contains at least one sealing strip which has an abutment means for the parting line covering the application of the sealing strip on the two dividing line delimiting components or concrete wall elements. Such a contact device may be a respective flat surface of the sealing strip or a surface of the sealing strip adapted to the concrete wall element in its shape. The joint anchor includes a base portion with an anchor shaft and a head portion with an anchor head for gripping or engaging behind a portion of at least one of the two concrete wall elements. The armature shaft is an arbitrarily shaped portion, in particular rod-shaped with z. B. round or rectangular cross section is formed. A holding or force transmission device spaced from the anchor head on the armature shaft serves for the direct or indirect support of the joint anchor on the sealing strip and can be embodied in a variety of configurations. A handling device of the joint anchor allows the positioning of the joint anchor and the force application to the joint anchor for prestressed fixing the sealing strip and in particular the application of force for separating the base part of the joint anchor when removing the sealing strip. The sealing strip further includes at least one recess for the passage of the joint anchor, in particular with its handling device and a support means for supporting the joint anchor on the holding device against movement in the direction of the anchor head.

If a predetermined breaking point is formed on the armature shaft between the anchor head and the holding device, a preferred breaking or cutting point is defined defined.

The holding or power transmission device may comprise a locking device in a simple design or be formed as a latching device, but other designs with screw threads with longitudinally adjustable nuts or with a number on the armature shaft lying behind each other formed openings for each engagement of a wedge or the like are possible.

The sealing strip can be a cross-sectional, angular, curved or tubular profile or have such profile sections. In particular, a section engaging in the parting line may have a configuration adapted to the cross section of the parting line.

In particular, the support means may comprise an engagement part which is releasably attachable to the sealing strip. The engagement member may be adapted in different embodiments to differently shaped joint anchors, so that for different joint anchors not the entire sealing strip, but only the engagement parts must be adjusted.

A joint anchor according to the invention, in particular an abovementioned device for sealing a parting line to be filled between two concrete wall elements or the like by means of a sealing strip, basically comprises a base section with an anchor shaft and a head section with an anchor head for gripping or engaging behind a section of at least one of the two concrete wall elements. The anchor head has at least one projection or anchor hook. A holding device, in particular latching device, for axially locking the joint anchor against a particular axial movement in the direction of the anchor head is provided on the base portion. Furthermore, a handling device for the joint anchor, in particular for applying an axial tensile force on the joint anchor provided. As a projection or anchor hook is every element into consideration, which allows a determination of the anchor head and the joint anchor against axial displacement, such. B. a one-sided or easier as well as a two-sided or double projection or hook. Such a projection or hook may be fixed or foldable or pivotable, so that it swiveled through a narrow parting line fits and can then be swung out to allow engagement behind the dividing line delimiting components.

The anchor shank preferably has a predetermined breaking or predetermined separation point, in particular between the holding device or latching device and the anchor head, so that the base section can be separated from the head section when the joint anchor is fixed in or at the parting line by a joint filling material.

Appropriately, the anchor head of the joint anchor and / or the armature shaft is elastically deformable such that it provides a biasing force on the armature shaft axially acting restoring force. The elastic deformability can be achieved by the material itself and / or by an appropriate design.

In principle, the joint anchor described is intended and suitable for a device according to the invention as well as for a method according to the invention.

In a parting line according to the invention, such a joint anchor extends in the parting line through the Fugenfüllmaterial and is held by this fugenvorderseitig an anchor shaft of the joint anchor at a separation point, in particular breaking point ends, and the back of an anchor head of the joint anchor is held by Fugenfüllmaterial. Through this lost joint anchor, the parting line can be made easily and inexpensively, in particular by the use of a Betonausgießmaterials as Fugenfüllmaterial.

The parting line is expediently according to the described method and / or under Use of a described device and / or a described joint anchor produced.

The invention therefore makes it possible to fill a parting line in a simple manner with a joint filling material which is simultaneously the pouring material or the concrete stiffener, so that the parting line according to the invention as well as the method is produced without its own separate joint filling or a separate joint filler. This also time for a prior curing of a special Fugenfüllmittels according to the prior art is not required. The strength of a parting line filled in accordance with the invention can be determined statically, since there is a uniform material structure in the parting line and the adjacent areas.

Two hollow or double wall elements 1 and 2 (please refer 1 and 2 ) are prepared in a known manner as precast concrete elements in a concrete plant and placed next to each other at their site for erecting a wall or wall. Each double wall element 1 . 2 has two spaced-apart flat concrete wall elements 3 and 4 by means of a reinforcement 5 in their mutual distance with an intermediate cavity 6 are held. The two double wall elements 1 and 2 are set apart from each other so that a parting line 7 between the two aligned concrete wall elements 3 and 3 respectively. 4 and 4 is formed. Every concrete wall element 3 . 4 contains, for example, a joint face 8th and an outside bevel 9 so that the parting line 7 in cross-section an inner channel section 10 with from the joint faces 8th formed parallel boundaries and a V-shaped channel opening 11 on the outside.

Before concreting the cavities 6 the from the double wall elements 1 and 2 formed wall are the joints 7 closed on the outside to prevent leakage of a Betonschlemme einzufüllenden. An inventive device for sealing or closing the parting line 7 contains a sealing strip 12 , to the two the parting line 7 delimiting concrete wall elements 3 . 4 is created so that it is the parting line 7 covered and against leakage of concrete sludge, which is also a joint filling material 13 forms (please refer 8th wherein the concrete stool in the cavity 6 is shown in sections), essentially seals, and a joint anchor 14 with which the sealing strip 12 on the two concrete wall elements 3 (respectively. 4 ) in the area of the parting line 7 is determined releasably.

In the in the 2 illustrated embodiment, the sealing strip 12 shaped in cross-section so as to conform to the contour of the V-shaped channel opening 11 adapts. The sealing strip contains this 12 a V-shaped middle section 15 for application to the two bevels 9 and two lateral plant legs 16 for application to the outer surfaces of the two concrete wall elements 3 respectively. 4 , in particular an attachment device of the sealing strip 12 form.

The explanation of the device according to the invention is carried out in the following, first with reference to an embodiment of the sealing strip 12 according to the 4 to 8th , This sealing strip 12 also contains a V-shaped middle section 15 , on the but on both sides at an angle against each other directed legs 17 connect, their end edges 18 a narrow longitudinal slot 19 limit. The sealing strip 12 thus forms a stable largely closed tubular profile with the narrow longitudinal slot 19 , which is opposite to a groove-like front edge 20 at the V-shaped middle section 15 the sealing strip 12 extends. In the front edge 20 are several slit-like recesses 21 or elongated holes formed in the longitudinal direction of the sealing strip 12 are arranged spaced from each other.

The joint anchor 14 (please refer 3 ) includes a base portion with an elongated rod-shaped armature shaft 22 with, for example, round or rectangular cross section and a head section with an anchor head 23 with two opposing anchor hooks 24 for engaging behind the two concrete wall elements 3 respectively. 4 , Distanced from the anchor head 23 contains the anchor shaft 22 a holding or power transmission device z. B. in the form of a latching device 25 , which are arranged as a double-sided locking teeth with a plurality of teeth 26 is formed along the anchor shaft 22 are arranged one behind the other and locking surfaces 27 having an engaging part 28 relative to a handle 29 Keep blocking the anchor head 23 opposite end of the joint anchor 14 forms. The engaging part 28 is for example from the two end edges 18 the thigh 17 formed or it is an independent component, as it is in 2 or in the 14 to 17 is shown. The handle 29 has, for example, the shape of a ring and is in the plane of the anchor hook 24 arranged.

The slot-like recesses 21 are with their length and width z. B. to the handle 29 adjusted so that the joint anchor 14 in a simple assembly process with the handle 29 ahead through the respective recess 21 from the side of the front edge 20 can be inserted through it.

When mounting the device is first at each recess 21 a joint anchor 14 with parallel to the recess 21 aligned handle 29 through this recess 21 and continue through the opposite longitudinal slot 19 stuck through (in 4 is the right joint anchor 14 shown in this position).

Subsequently, the sealing strip 12 with the example of three joint anchors 14 with her middle section 15 at the parting line 7 arranged, wherein the middle section 15 to the bevels 9 is created and thus the parting line 7 is substantially sealed. Every joint anchor 14 is doing through the parting line 7 inserted and positioned so that its anchor shaft 22 behind the parting line 7 extends and therefore the anchor head 23 inside in the cavity 6 behind the parting line 7 is arranged (see 6 ).

That's what every joint anchor will do 14 by means of his handle 29 about 90 ° around its armature 22 turned (see 4 , Illustration of the middle joint anchor 14 , such as 7 ). The locking device 25 or the teeth on the armature shaft 22 is located within the profile of the sealing rail 12 and the teeth 26 thereby become transverse to the longitudinal slot 19 placed in a position in which they can be locked or locked in the next assembly step. At the same time the anchor head pivots 23 by 90 °, leaving the two anchor hooks 24 transverse to the parting line 7 are aligned and each have an anchoring edge 30 of the concrete wall element 3 . 4 grabbing the back or inside of the concrete wall element 3 . 4 the parting line 7 limited.

Now everyone gets joint anchors 14 by means of his handle 29 from the concrete wall element 3 . 4 or the sealing rail 12 pulled away until the two anchor hooks 24 with their tips at the anchorage edges 30 the two concrete wall elements 3 . 4 firmly in place (see 8th and 4 , Illustration of the left joint anchor 14 ). When tightening the joint anchor 14 the section of the armature shaft moves 22 with the locking device 25 or with your teeth 26 through the longitudinal slot 19 , The width of the anchor shaft 22 at the latching device 25 in the direction of the protruding teeth 26 and the width of the longitudinal slot 19 are coordinated so that the two legs 17 over the tips of the teeth 26 can slide, due to the elasticity of the z. B. made of a steel sheet leg 17 the sealing strip 12 the end edges 18 however in the recesses 30 between two teeth 26 can engage and engage the associated locking surfaces 27 the teeth 26 can engage in latching or latching engagement when the joint anchor 14 has taken his holding, clamping or locking position.

The anchor head 23 or the two anchor hooks 24 have due to the material properties and / or design a certain elasticity, so that the joint anchor 14 at high tensile strength and elastic yield of anchor hooks 24 is brought into a detent position in which the end edges 18 the thigh 17 a detent position on the teeth 26 safely take. When the traction stops and the handle stops 29 is released, produce the elastically biased anchor hooks 24 a clamping and holding force of the joint anchor 14 in the direction of the armature shaft 22 and about the locking device 25 on the thighs 17 the sealing strip 12 , thus, with this clamping force in the parting line 7 is pressed and this seals. The locking device 25 as an example of a power transmission device thus brings the clamping force from the joint anchor 14 on the sealing strip 12 ,

After mounting the sealing strip 12 becomes the cavity 6 filled with Betonschlemme, which up into the parting line 7 and to the sealing strip 12 flows. After curing, the concrete sling can be removed by pulling on the handle 29 the anchor shaft 22 at a predetermined breaking point 31 be disconnected, wherein the tensile force exceeds the force applied for locking force. The breaking point 31 is conveniently located between the anchor head 23 and the resting section 25 and, in particular, to the post appointed in accordance with 8th at the recess 21 is arranged (the predetermined breaking point 31 is in 3 only shown schematically). The front or head section of the joint anchor 14 remains with the anchor head 23 thus in the hardened Betonschlemme or Fugenfüllmaterial 13 , The sealing strip 12 is therefore after the separation of the joint anchor 14 from the parting line 7 releasably and optionally reusable after cleaning residues of Betonschlemme.

The filled parting line 7 gets an outer V-shape with the two bevels 9 and the intermediate V-shaped groove 32 which has a comparatively smooth surface.
