• two anchoring devices by means of which the joint bridging device can be anchored to two structural parts separated by a joint and
• a bridging device which is connected on its opposite longitudinal sides to one of the anchoring devices, changes in position of the structural parts relative to one another being able to be compensated for by a change in shape of the bridging device,

wherein the anchoring devices are composed of a lower part which can be anchored to the respective structural part and an upper part which is connected to the lower part in a force-transmitting manner by means of a plurality of screws and which is connected to the bridging device, the upper part at least essentially in the installed state of the lower part is non-destructively removable.

State of the art

In order to prevent stress cracks in structures due to environmental or load-related factors, the structures are often provided with targeted joints, which divide the structures into individual parts of the structure. The joints enable changes in the position of the building parts relative to each other and prematurely avert the forces acting on the building, which induce the stress cracks.

By means of joint bridging devices, the individual parts of the building can be bridged despite the relative movements to each other in order to create a flat, gap-free transition surface. For this purpose, the joint bridging devices are non-positively connected to the structural parts and compensate for the relative movements by means of bridging and anchoring devices that are movably connected to one another. While the anchoring devices are screwed to the respective structural parts and are partially covered by the floor covering, the bridging devices, on the other hand, run as flat as possible with the surface of the floor covering over the joints.

With regard to signs of wear and tear of the bridging device (e.g. wear of a profiling of the surface which serves to prevent slipping) or due to maintenance work, it may be necessary that at least parts of the joint bridging device, in particular the bridging device, can be replaced or temporarily removed.

However, requests regarding a changed appearance of the visible surface of the joint bridging device can also necessitate an exchange of the bridging device and the associated upper parts of the anchoring devices. For example, you can switch between different types of anodization of extruded aluminum profiles or from an anodized to a non-anodized surface or vice versa. Finally, necessary changes in the thickness of the floor covering can create a need for an exchange of the bridging device and upper parts of the anchoring devices.

A device described above for bridging joints between two structural parts is based on the patent application DE 38 28 980 A1 forth. Here a joint bridging device is disclosed, which consists of two anchoring devices and a bridging device. The bridging device has two bridging members which engage telescopically and are each articulated to one of the anchoring devices via an arcuate groove with an arcuate spring adapted to compensate for relative movements between the structural parts. The anchoring devices are screwed to the structural parts and then partially covered with a layer of mortar or another floor covering, so that a flat floor surface is created overall. The anchoring devices are preferably constructed in two parts as an upper and lower part, in order to enable the gap bridging device to be adapted to the thickness of the floor covering by the choice of the upper part.

Disadvantageously, however, the upper and lower parts of the anchoring devices directly adjoin the floor covering. This means that the anchoring devices for replacing the same cannot be separated from the building parts without removing the adjacent floor covering. This must be accompanied by extensive cutting, grinding and chiseling work, which means a great deal of noise and dirt and then require extensive cleaning work before it can be reassembled. An exchange of the bridging elements, which before the installation of the Joint bridging device can be inserted into the arcuate groove of the upper parts, is also only possible with considerable effort. In addition, the separation of the upper part and lower part requires a relative displacement of the aforementioned components over their entire length, so that removal of the upper part is hardly feasible in practice.

Another joint bridging device, which is particularly suitable for use in humid environments, can be found in the product "FPG 90 NI kF" from "MIGUA". The joint bridging device described here has an elastic bridging device which is clamped on the side facing away from the joints between a lower part and an upper part of an anchoring device. The edge areas of the bridging device serve as a seal against water and are enclosed by a downwardly bent section of the upper part of the anchoring devices. The lower parts of the anchoring devices are screwed to the respective structural part and are surrounded by the floor covering.

In order to remove the bridging device from an already installed joint bridging device without removing the floor covering, the floor covering must disadvantageously be applied due to the downwardly bent section of the upper part in such a way that there is a gap between the upper part of the anchoring device and the floor covering, so that this Upper part does not come into contact with the floor covering. However, the formation of a gap leads to an unwanted accumulation of moisture and dirt in the same.

From the DE 30 15 011 A1 an expansion joint bridging device is known in which a tongue-shaped bridging element engages in a fork-shaped bridging element, the bridging unit formed in this way being fastened on both opposite sides by means of a round bar in each case in a correspondingly complementary bearing groove of the respective anchoring unit, without an articulated connection being provided would be so that the previously known device is only suitable for compensating for horizontal movements of the structural parts defining the joint, but not for compensating for vertical movements, as is the case with the present invention in the articulated connection between the bridging unit and the anchoring units, in particular the upper part thereof. In addition, the upper parts of the anchoring units are only plugged onto the lower parts, all holding forces being generated solely by frictional forces or clamping forces.

From the DE 38 11 082 C1 Another device for bridging a joint is known in which there is articulation within the bridging device and in which the upper parts of the anchoring units are connected to the respective lower part by means of screws. The screws engage in nuts which are mounted so as to be longitudinally displaceable in undercut grooves in the lower parts of the anchoring device. In order to be able to absorb the necessary forces acting in the vertical direction during operation of the device, the upper parts have a thickness that is not too small, which is why, when the upper parts are removed, adjacent areas of the floor have to be removed or damaged to a not inconsiderable extent.

Further bridging devices are from the documents DE 102 08 359 A1 , DE 43 03 369 C1 and US 5,384,996 known. All previously known devices have in common that when the upper part of the anchoring units is replaced, major damage to the adjacent floor covering is unavoidable, or that comparatively weak upper parts are connected to the associated lower parts only by means of clamping or frictional forces.

In general, difficulties and effort when replacing the bridging device tend to mean a longer loss of use of the affected section of the building and thus often considerable financial losses.

task

It is an object of the present invention to develop an alternative joint bridging device which is distinguished by a particularly simple possibility for removing the bridging device.

solution

Starting from the joint bridging device mentioned at the outset, the above object is achieved in that a separating web of the lower part, which extends on a side of the upper part facing away from the joint, next to the latter in the direction of the surface of a floor covering adjoining the joint bridging device, the distance being one the surface of the web facing the end face of the web from the surface of the floor covering is a maximum of 8 mm, preferably a maximum of 6 mm, further preferably a maximum of 4 mm, the upper part and the lower part being supported against one another in the region of opposing contact surfaces, so that during operation the Joint bridging device occurring forces perpendicular to the surface of the floor covering are transferable and wherein the contact surfaces one have a greater distance from the surface of the floor covering than the end face of the partition. In this context, “next to” means an arrangement with a greater distance, measured in the horizontal direction, of the separating web from the joint than that of the upper part from the joint.

A particular advantage of the device according to the invention is that a height of a contact area between the upper part of the anchoring device and the floor covering is at most 8 mm, preferably at most 6 mm, further preferably at most 4 mm. This prevents the floor covering, for example a mortar compound, an adhesive or an elastic joint compound, from holding the upper parts of the anchoring devices in such a way that removal of the same is only possible by removing or destroying the surrounding floor covering. Rather, the upper part is only connected to the bottom material at the small contact surface, which is why the damage during dismantling can be kept low or dismantling forces small.

In the joint bridging device according to the invention, therefore, each lower part of the anchoring unit preferably has an L shape, in such a way that the upper part is inserted into the L, the leg of which is perpendicular to the floor covering and is formed by the separating web. The respective upper part has a thickness measured perpendicular to the plane of this floor covering, which is at least 50% of the total thickness of the anchoring unit, i.e. the distance of the underside of the lower part facing the respective component from the upper side of the respective upper part forming an upper side of the joint bridging device.

In addition, there is preferably an uppermost horizontal tangential plane to the lower part, namely in a section thereof outside the separating web, i.e. on the side of the separator facing the joint, lower than the upper end face of the separator. Typically, the aforementioned tangential plane in the section of the lower part facing the joint essentially corresponds to the contact area of the lower part defined above. Further preferably, there should be an opening cross-section of a preferably undercut groove in the aforementioned tangential plane, which serves to receive nuts in order to be able to screw in screws passed through the upper part in order to connect the upper part and lower part to one another.

The direction of disassembly of the upper parts of the anchoring device is preferably perpendicular to a contact surface of the lower parts of the anchoring device. It is also preferred that the bridging device is dismantled or assembled together, that is to say coherently, with the two upper parts of the anchoring units coupled therewith.

Preferably, the area adjacent to the upper part of the anchoring device is not completely filled with the floor covering, but is closed by means of an elastic joint material. The thickness of the layer only has to correspond to the distance described above (if it exists at all) between the surface of the floor covering and the end face of the separating web. As a result, the replacement or removal of the upper part, and thus also the bridging device, can be carried out particularly easily, for example by means of a knife, by separating the elastic joint material, without having to remove part of the actual, solid floor covering.

In one embodiment of the joint bridging device according to the invention, the end face of the separating web extends up to a surface of the upper part of the anchoring device. This embodiment has the advantage that it is ensured that the upper part of the anchoring device is completely separated from the floor covering by the separating web of the lower part. This means that no elastic joint material is required to close the surfaces adjacent to the separating web. The adjacent area can be completely filled up with the floor covering. The upper parts of the anchoring devices and the bridging device can thus be replaced particularly easily — without removing the floor covering — in the event of signs of wear or changed requirements for the joint bridging device.

According to a particularly preferred embodiment of the invention, the end face of the separating web directed away from the lower part is designed to be consistently flat. This means that the end face has no steps, waves, recesses, notches or the like, but rather runs straight and in particular parallel to a contact surface of the lower part of the anchoring device. In this way, the separating web can best fulfill its task of forming a shield or separation from the floor covering that facilitates the detachment of the upper part from the lower part. In particular, if the end face of the separating web extends to the surface of the floor covering, a non-flat shape of the end face is hardly acceptable from an aesthetic point of view, but would also detach the floor covering or an elastic jointing compound from the upper part in the area of depressions in the end face unnecessary make it more difficult if material of the floor covering or joint material would reach up to the upper part in the area of the depressions.

According to an advantageous development, the upper part of the anchoring device does not extend further from the joint than to a side surface of the separating web of the lower part facing away from the joint. Such an embodiment has the advantage that the upper part of the anchoring device does not come into contact with the floor covering beyond the contact area described at the beginning. This leads to the fact that the top parts with the bridging device attached to them can be removed particularly easily without having to keep a gap between the top part and the floor covering free.

The bridging device can be designed, for example, as an elastic plastic element (in particular rubber or other elastomers). If the structural parts move relative to one another, the deformability of the plastic element ensures that the joint is bridged without the formation of cracks despite the movement. With regard to the mechanical strength of the joint bridging device, however, it can alternatively be advantageous if the bridging device is not formed by an elastic bridging member, but by a plurality of rigid bridging members (made of metal or plastic, in particular those with fiber reinforcement) which are movable relative to one another , Changes in position of the structural parts relative to one another can be compensated for by at least one relative movement of adjacent bridging elements. It is conceivable that the bridging device is formed by two, telescopically interlocking, metallic bridging members, which compensate for the relative movements of the structural parts to one another and withstand a higher load due to their material properties. This means that the joint bridging device can also be driven on for heavy vehicles, for example.

In one embodiment of the joint bridging device according to the invention, both upper parts and the bridging device connected to them can be removed from the lower parts together, essentially non-destructively, in the installed state of the lower parts of the anchoring device. Due to the non-destructive removal of the upper parts from the lower parts, in the event of a defect or wear of an upper part or the bridging device, corresponding new parts can be used particularly easily without having to replace the lower part. This leads in particular to a reduced work and material expenditure.

According to a preferred embodiment of the invention, it is provided that the joint bridging device has at least one connecting element, preferably a plurality thereof, by means of which the upper part of the anchoring device can be anchored to the lower part of the anchoring device. In order to obtain a secure hold of the upper part and the bridging device connected to it, the upper part must be non-positively connected to the lower parts of the anchoring device which are screwed or mortared to the respective structural parts. The connecting elements, which can each be in the form of a screw and (rectangular) nut, for example, are inserted into the upper or lower part for this purpose, screws guided through the upper part of the anchoring device being connected to nuts mounted in the lower part.

An advantageous embodiment of the invention provides that the lower part of the anchoring device has a preferably undercut groove, wherein a cross section of the groove is preferably T-shaped. A groove is desirable insofar as this creates a receptacle for the nut of the at least one connecting element, which is positively connected to the lower part, whereby lateral forces that are introduced into the upper parts and / or the bridging device from the outside also result in the Lower parts can be removed. The cross section of the groove is preferably T-shaped, so that the upper part can be coupled to the lower part by forming a corresponding cross section.

In one embodiment of the joint bridging device according to the invention, a width of a nut of a connecting element is less than a length of the nut of the connecting element, the width of the nut being less than a minimum width of the groove of the lower part of the anchoring device and the length of the connecting element being greater than the minimum width the groove of the lower part of the anchoring device.

The above aspect ratio enables the nut to be simply inserted into the groove of the lower part in a first orientation. The increased length of the nut compared to the minimum width of the groove of the lower part ensures that the nut, which is preferably essentially designed as a rectangular nut, cannot be rotated without a stop in the groove when connected with a screw. Rather, the nut blocks in a second orientation in the groove of the lower part and thus prevents further turning, so that a continued positive connection between the upper and lower part of the anchoring device can be achieved if the screw is screwed in further.

It is preferably provided that two diagonally arranged edges of the nut are rounded. Such an embodiment is particularly well suited to connecting the upper parts to the lower parts of the anchoring device. The formation of the rounded edges means that the nut can be tilted in the groove of the lower part of the anchoring device when the nut rotates. To do this, the nut must be turned in such a way that the rounded edges point in the direction of the opposite side surfaces of the groove of the lower part. Due to the increased length of the nut in relation to the maximum width of the groove, the same finally tilts in the groove. As a result, manual holding of the nut, such as when using a freely rotating nut, is no longer necessary.

a vertical section through a further joint bridging device according to the invention

Figure 1 shows a vertical section through a joint bridging device 1 according to the invention, which on two not in the Figure 1 shown parts of the building can be anchored. The joint bridging device 1 is designed in the manner of a rail and comprises two anchoring devices 2, each of which is elongated and runs parallel to a joint 4, and a bridging device 3. The anchoring devices 2 each comprise an upper part 7 and a lower part 8, the upper part 7 forming the lower part 8 - and is non-positively connected. The two lower parts 8 of the anchoring devices 2 are fastened to the structural parts separated by the joint 4. The spanning the joint 4 Bridging device 3 has two bridging elements 5, 6, which telescopically engage in the form of a tongue and groove connection.

The first bridging member 5 of the bridging device 3 has an I-shaped cross section and is articulated with the arcuate end 9 in an adapted arcuate groove 10 of the upper part 7 of the first anchoring device 2. The groove 10 of the upper part 7 is formed by an outer cylindrical and an inner cylindrical wall section. In order to prevent the entry of moisture or dirt into the groove 10 of the upper part 7 - and thus to avoid impairment of the movement compensation - the upper part 7 has a groove in the outer cylindrical section, in which a sealing cord 11 is inserted. The straight end 12 of the I-shaped bridging member 5 acts as a spring 16 and extends telescopically into a correspondingly designed groove 13 of the second bridging member 6. On a side surface facing away from the joint 4, the first bridging member 5 also has a groove provided with a sealing cord 11, which prevents moisture or dirt from entering the groove 13 of the second bridging element 6.

The groove 13 of the second bridging member 6 is delimited by two legs 14 which taper in cross section. Analogously to the first bridging member 5, the arcuate end 15 of the second bridging member 6 facing away from the joint 4 is anchored in a corresponding groove 10 in the upper part of the second anchoring device 2.

Due to the telescopic engagement of the first bridging element 5 in the groove 13 of the second bridging element 6, on the one hand horizontal movements of the two structural parts with respect to one another can essentially be compensated for by a displacement of the spring 16 in the groove 13. By means of the articulated connection of the bridging members 5, 6 to the respective upper parts 7 of the anchoring devices 2, any vertical relative movements of the structural parts with respect to one another can also be compensated for without creating a step in the area of the transition between the structural parts.

The lower parts 8 of the anchoring devices 2 are designed in the form of a T-slot rail 17. The bottom surface of the T-slot rail is extended on one side. The extension 18 of the T-slot rail 17 is provided with perforations and elongated holes, which mi Figure 2 be described in order to connect the joint bridging device 1 to the structural parts by means of screws. Furthermore, the T-slot rail 17 has, on the side surface facing away from the joint 4, in extension of the same, a separating web 19 which projects above the surface of the T-slot rail 17 facing the joint 4.

The section of the upper part 7 of the anchoring devices 2 facing the structural parts is T-shaped as a counterpart to the lower part and can thus be inserted in a form-fitting manner in an adapted groove 20 of the lower part 8. The undercut lower portion 21 of the groove 20 is not filled by the upper part and remains for the use of nuts 31, which are in connection with Figure 3 be described freely.

On the side facing the joint 4, the upper part 7 is provided with the groove 10 described at the outset in order to hold the respective bridging member 5, 6. The cross-sectional shape of the upper part 7 is adapted to the shape of the lower part 8 on the side facing away from the joint 4. An upper, horizontal web 23 of the upper part 7 lies on an end face 24 of the separating web 19.

The upper part 7 is provided with bores 25 at regular intervals. In order to connect the upper parts 7 to the lower parts 8 already screwed to the structural parts, screws 26 are passed through the bores 25 of the upper parts 7 and screwed to the underside with nuts 31. A screw 26 and nut 31 each form a connecting element 22 in pairs.

In order to achieve a level transition between the joint bridging device 1 and the adjacent floor, the space above a level defined by the extended floor area of the lower part 8 is filled with a floor covering, for example screed or floor slabs. Due to the design of the separating web 19, a contact area 27 between the floor covering and the upper part 7 is approximately 3 mm in the present case. In order to ensure easy removal of the upper parts 7 and the bridging device 3, the area immediately adjacent to the contact surface 27 is not closed with the floor covering, but with an elastic joint material which is relatively simple, e.g. cut with a cutter knife and then removed again to expose the contact surface 27.

All components of the joint bridging device 1 (apart from the sealing cords) are made of extruded aluminum, but can in principle also be made of steel or other metals. Alternatively, plastic materials, in particular those with fiber reinforcement, are also conceivable.

The Figure 2 shows the joint bridging device 1 according to the invention Figure 1 in a three-dimensional view. In the Figure 2 the bores 28 and slots 29 of the lower parts 8 of the anchoring devices 2 are clearly visible. By choosing Elongated holes 29 make it possible to place the fastening means, such as screws, as desired on the surface of the structural parts in order to fasten the joint bridging device 1. In the Figure 2 the upper parts 7 are non-positively connected to the lower parts 8 by means of screws 26 and nuts 31 located in the groove 20.

The Figure 3 corresponds essentially to that Figure 1 However, a screw 26, the upper part 7 of the anchoring device 2, the nut 31 and the lower part 8 of the anchoring device 2 are shown spaced apart from one another in the manner of an exploded drawing in order to provide a better overview of the individual components.

The width of the nut 31 is smaller than the minimum width B _{min of} the groove 20 of the lower part 8. The length 33 of the nut 31, on the other hand, is larger than the maximum width B _{max of} the groove 20 of the lower part 8 and secondly than the minimum width B _min . Furthermore, diagonal edges of the nut 31 are rounded.

In order to connect the upper part 7 to a lower part 8 already screwed to the respective structural part, as in FIG Figure 3 represented by line 30, a screw 26 is guided through the bore 28 of the upper part 7. On its underside, the nut 31 provided with a thread adapted to the screw 26 is screwed to the screw 26. The upper part 7 provided with the screw 26 and the nut 31 can then be inserted into the groove 20 of the lower part 8. For this purpose, the nut 31 must be turned into a position perpendicular to the orientation shown. Since the width 32 of the nut 31 is made smaller than the minimum width B _{min of} the groove 20 of the lower part 8, the upper part 7 with the nut 31 can be inserted into the groove 20. In order to obtain a firm connection between the two profiles, the screw 26 is turned. The nut 31 lying in the groove 20 is also moved in a first step and then canted as soon as the non-rounded edges come into contact with the walls of the groove 20. Advantageously, the nuts 31 do not have to be inserted laterally into the groove 20 over long distances before the installation of the lower parts 8 and brought as precisely as possible to the position of the respective bore 25 of the upper part 7 due to the above shape.

Figure 4 shows another joint bridging device 1 according to the invention, in which the in turn flat and completely straight end face 24 of the separating webs 19 extends to the surface 34 of the upper parts 7 of the anchoring devices 2. The upper parts 7 of the anchoring devices 2 are thus completely separated from the floor covering by the separating webs 19. For the removal of the upper parts 7 and the associated bridging device 3, such a design of the separating webs 19 is special advantageous because the above components can thus be removed without removing or damaging the floor covering. On the other hand, the end face 24 of the separating webs 19 is visible in this embodiment, so that material differences between the upper parts 7 and the lower parts 8 would be apparent, which is the case in the embodiment according to FIGS Figures 1 to 3 is not the case.
