[0001] Device for bridging a joint between building components

[0002] Description

[0003] Introduction

[0004] The invention relates to a device for bridging a joint between building parts, wherein the joint consists of at least two abutting sections, of which a first section runs in a horizontal direction and a second section runs in a vertical direction, wherein the device consists of at least two abutting parts, of which a first part assigned to the first section of the joint extends in a first, horizontal direction and a second part assigned to the second section of the joint extends in a second, in particular vertical, direction, wherein the first part and the second part of the device are connected at a transition point at which the first section of the joint abuts the second section of the joint, forming an angle, in particular a right angle, wherein each part of the device has two anchoring units,of which one is arranged on each of two opposing structural parts delimiting the associated section of the joint in a transverse direction, and a bridging unit connecting the two anchoring units, which, together with the respectively associated anchoring units, allows a change in a joint width measured in the transverse direction, wherein two transition lines running parallel to one another in the first direction, visible in a view of the first part of the device, each between the bridging unit of the first part of the device on the one hand and the two associated anchoring units of the first part of the device on the other hand, at the transition point to two corresponding, also parallel to one another, but running in the second direction,in a view of the second part of the device, visible transition lines between the bridging unit of the second part of the device, on the one hand, and the two anchoring units of the second part of the device, on the other hand, abut without offset, wherein a width of the first part of the device, as perceived in a view of the device, in its installed state corresponds to a width of the second part of the device, as perceived in a view of the device, in its installed state, and wherein the bridging unit of the first part of the device is compressible in a vertical direction such that it can be walked on by persons and / or driven over by an industrial truck, wherein the first part of the device and the second part of the device form a blunt joint at the transition point.

[0005] Accessibility with an industrial truck should in particular mean that the load introduced into the device as a linear load, for example by a forklift truck (e.g. a so-called 15-tonne forklift truck according to DIN) via its (usually pneumatic) wheels or by a pallet truck via its wheels typically designed as "hard rollers", can be absorbed permanently without damage. A blunt impact is defined in the context of the present application as a straight contact line or contact surface running at right angles to both the first direction and the second direction between the two abutting parts of the device. In particular, the contact line or surface is not stepped or curved and has no steps or projections in its course.

[0006] Larger structures in the form of buildings are deliberately divided into different structural bodies (structural components), between which a gap or space (structural joint) is intentionally created to allow for different movements – also due to thermal expansion – of the adjacent structural components without the occurrence of uncontrolled stress cracks within the material of the individual structural components. Such joints often extend both between horizontally aligned structural components, such as floors and ceilings, and between vertically aligned structural components, particularly wall panels. A joint, which is then considered a unit, often runs within a common plane both horizontally between floor and / or ceiling elements of a building and between adjacent wall elements of the same building.The devices intended to bridge such a circumferential structural joint therefore give the impression of a self-contained frame or casing when installed.

[0007] Devices for bridging structural joints differ fundamentally from one another depending on the arrangement and orientation of the joint. The design principles of devices for bridging structural joints in floor areas are tailored to the type of load the device will be subjected to during the building's respective use (pedestrian traffic, vehicle traffic, e.g. forklift trucks or other motor vehicles, as in parking garages) and / or any requirements for the device to be leak-proof (preventing the penetration of liquids containing de-icing salt, e.g. in parking garages). Joint bridging devices in floor areas are therefore often very complex and designed to withstand high loads and are correspondingly expensive. In contrast, joint bridging devices are used in the area of ​​vertically aligned joints in walls orThe primary task of horizontally aligned joints in the ceiling area is to create a “clean”, durable and visually appealing joint finish, without any special requirements being placed on the mechanical strength or tightness of the joint.

[0008] Due to the aforementioned, significantly different requirements for devices used to bridge joints in the floor area on the one hand and joints in the wall and ceiling area on the other, the construction methods and also the visual appearance often differ significantly. In the state of the art, it is therefore not uncommon, even for purely aesthetic reasons, to cover a frame-shaped, circumferential joint in the area of ​​the floor as well as the adjoining walls and the adjoining ceiling with one and the same joint profile. In order to meet the mechanical properties required in the floor area, classic profiles are used for this purpose, which allow for sufficiently large load transfer and dissipation into the building. However, such devices are usually quite massive in their construction and therefore material-intensive and expensive.Alternatively, floor joint bridging devices with correspondingly high mechanical load capacity are combined with joint bridging devices specifically designed for use in walls and ceilings, and therefore only designed for low mechanical stress. However, such joint bridging devices have a different appearance when installed than the aforementioned floor joint bridging devices. This results in a disadvantageous combination of devices from an aesthetic point of view, with the transition points between the floor and adjacent walls becoming particularly unsightly.

[0009] DE 19 363 648 U describes a joint bridging device, particularly for roadways, which is characterized in that the device is provided with an end piece at each end, which causes an arcuate deflection of the surface from the horizontal to the vertical. The previously known device has two horizontally aligned anchoring units and a bridging unit in the form of a hollow-chamber rubber profile with upper ribbing, clamped between them in a dovetail-shaped cavity. At each end, the horizontal anchoring units are adjoined by a vertical anchoring unit extending in the horizontal direction, between which a bridging unit designed as a solid rubber profile is clamped—also in a dovetail-shaped cavity.In this design, the horizontal and vertical profile sections do not butt against each other; instead, the joint between the anchoring profiles is offset by a certain horizontal dimension from the joint between the bridging units. This offset may be due to preventing sealing problems in the joint area.

[0010] Task

[0011] The invention is based on the object of providing a joint bridging device that is particularly suitable for bridging joints that have both horizontal and vertical sections and therefore must meet different requirements for the respective tasks to be performed. The device should be characterized in particular by being able to meet high aesthetic standards and, in particular, by continuing the visual appearance of the horizontal bridging in the vertical bridging.

[0012] Solution

[0013] Starting with a device of the type described above, the underlying object is achieved in that the bridging unit of the second part of the device comprises an elastically deformable foam material. The foam material preferably has a closed foam skin on a side facing away from the bridged joint, i.e., facing the space equipped with the device.

[0014] The invention is based on the finding that the second part of the device, which is to be mounted in the wall or ceiling area, does not need to have any special mechanical properties compared to the first part of the device used in the floor area. Rather, the area of ​​the wall or ceiling area requires a special mechanical properties.

[0015] The purpose of the ceiling joint section of the overall L-, U-, or frame-shaped device (and also the joint underneath to be bridged) is simply to create a visually clean and "tight" seal, which, for example, prevents dirt, insects, or small animals from penetrating the joint or from entering the room provided with the device. Such a seal is achieved very simply by using an elastically deformable foam material as a bridging unit, which does not require any sliding or pivoting movement, as is often the case with devices for bridging floor joints, requiring rather complicated structural solutions to compensate for the movements to be compensated.In a so-called "zero position" ("neutral position") of the joint, the bridging unit is in such a pre-compressed state that, even when the joint expands to its maximum expected width, it still bears against two opposing structural elements forming the joint with a certain residual pre-stress. If the joint is reduced to its minimum expected width, the foam material of the bridging unit must still have a residual compressibility, or at least still be in an elastic deformation state, so that upon a subsequent re-increase in the width of the joint, the foam material returns to an expanded state. Therefore, if the bridging unit is subject to compressive stress in all conceivable width states of the joint, i.e.If the width of the bridging unit is chosen to be correspondingly large, the force exerted by the bridging unit of the second part of the device on the two opposite anchoring units can be sufficient to fix the anchoring units to the opposite walls of the joint and thus to fix the second part of the device in the joint solely by clamping force.

[0016] The bridging unit preferably has a foam skin, which is preferably arranged on the side of the bridging unit facing the room (i.e., the side facing away from the joint). The foam skin is characterized by a very smooth surface, which facilitates any cleaning and largely prevents dirt from adhering. The foam material of the bridging unit can generally be open-cell or closed-cell. Preferably, a material known as cellular rubber or sponge rubber is used for the bridging unit.

[0017] Further preferably, a surface of the bridging unit facing away from the joint is set back from a surface of the respective bridging unit that protrudes furthest from the joint. In this way, the foam material of the bridging unit is protected and also secured against vandalism, particularly in the form of deliberate tearing or breaking out of pieces.The areas of the anchoring units of the second part of the device that protrude furthest from the joint are preferably made of metal, in particular aluminum or (stainless) steel, or a hard plastic and therefore offer sufficient resistance to deformation, such as could occur due to external forces during normal use of such a wall or ceiling joint bridging device, in particular in the form of leaning by a person or by being bumped into by a person or an object (cleaning tool or wheelchair, walker, or similar).

[0018] A particularly advantageous embodiment of the invention is that at least one anchoring unit, preferably both anchoring units, of the first part of the device each has a groove extending in the longitudinal direction of the joint, into which a spring of the bridging unit of the first part of the device or a spring connected to the anchoring unit opposite the anchoring unit having the groove engages. The tongue-and-groove principle for compensating for length changes has long been used in joint bridging devices, particularly those in the floor area, and has proven successful.

[0019] If the at least one groove in one of the anchoring units, preferably both grooves in the two anchoring units, of the first part of the device are undercut, wherein a spring of one of the bridging units engaging in the at least one undercut groove has a projection extending into an undercut region of the at least one groove, an unintentional protrusion of the spring of at least one of the bridging units can be prevented. In this context, it is particularly advantageous if the spring is angled or bent at at least one end section.

[0020] A further advantageous development of the invention is that the anchoring units of the first part of the device are each connected exclusively to a horizontally oriented edge strip of the respective structural component adjacent to the horizontally extending part of the joint. This allows for considerable freedom in the orientation and positioning of the anchoring units during the assembly of the first part of the device.

[0021] While the anchoring units of the first part of the device extending in the horizontal direction can be substantially Z-shaped, it is advantageous with regard to the anchoring units of the second part of the device extending in particular in the vertical direction if these are substantially C- or U-shaped.

[0022] In the latter embodiment, in the part of the device that closes the wall or ceiling joint, it is advantageous if the anchoring units are connected, preferably exclusively, to those edge strips of the respective structural components that delimit the section of the joint, particularly in the vertical direction, and face each other. In this case, a setback of the bridging unit made of foam material is possible even if the protrusion of the second part of the device beyond a joint opening cross-section, as defined by the opposing structural components, is small. Such a small protrusion enables the realization of thin application layers, such as plaster, a thermal insulation composite system, or similar, on the structural components in their raw state (typically concrete or masonry).

[0023] In this context, it is advantageous if the anchoring units each have an edge strip that – in a cross-sectional view – extends from a corner area of ​​the respective anchoring unit away from the joint. This creates a kind of depth stop for the anchoring units, simplifying the installation of the second part of the device.

[0024] In a further development of the invention, it can be provided that the foam material of the bridging unit is located between the two anchoring units of the second part of the device, which part extends in particular in the vertical direction and is under compressive stress at all joint widths resulting from thermal expansion effects.

[0025] If the two anchoring units of the second part of the device, which extends in particular in the vertical direction, each have - in a cross-sectional view - an angled edge section extending towards the interior of the joint, with mutually facing surfaces of the edge sections defining the transition lines, in particular the vertical ones, of the second part of the device, this results in a visually particularly appealing and also particularly advantageous design with regard to a possible risk of injury. Angled edge sections, which should also be understood to include those with a rounded geometry, eliminate the risk of cuts, even if the anchoring units are

[0026] Bending can be made from sheet material, especially stainless steel sheet or other sheet metal.

[0027] Furthermore, according to the invention, it is further provided that a depth of the bridging unit measured toward the interior of the second section of the joint is smaller than a depth of the anchoring unit measured toward the interior of the second section of the joint. This makes it possible to create a free space emanating from a front opening cross-section between the opposing anchoring units and extending toward the interior of the joint, at the end of which the foam material of the bridging unit begins. The joint therefore appears in the classic style of a so-called shadow gap and is particularly visually appealing.

[0028] A further embodiment of the invention further provides that a gap located between the two anchoring units of the second part of the device and extending in the second direction has a width measured perpendicular to the second direction that is smaller than a width of the bridging unit of the second part of the device, also measured perpendicular to the second direction, wherein an overlapping region is preferably formed by a C- or U-leg of the respective anchoring unit. This results in the respective anchoring unit projecting beyond the bridging unit on both sides - in a vertical projection onto the second part of the device. As a result, once the device has been installed, it is no longer possible to pull the bridging unit out of the joint, since the anchoring units would offer insurmountable resistance to such a movement.This reduces the device’s vulnerability to vandalism.

[0029] Finally, according to the invention, it can also be provided that four structural parts, namely two structural parts forming a floor and two structural parts forming a wall, abut one another in the area of ​​the joint.

[0030] Example

[0031] The invention is explained in more detail below using an exemplary embodiment illustrated in the figures. It shows:

[0032] Figure 1 : A perspective view of a device cut off on both sides with a transition point between a floor and a wall,

[0033] Figure 2a: a cross-sectional view of the device with a joint in its maximum strain state,

[0034] Figure 2b: as Figure 2a, but with the joint in a neutral state and

[0035] Figure 2c: as Figure 2a, but with the joint in a minimal strain state.

[0036] A device 1 shown in Figure 1 consists of a first part 2, which serves to bridge a first, horizontally running section of a joint 27 (see Figures 2a to 2c) not shown in Figure 1, and a second part 3 abutting thereon, which serves to bridge a second section of the joint 27 shown in Figure 1, this second section running in the vertical direction. Both parts 2 and 3 of the device 1 abut one another at a transition point 4, forming a right angle. It is understood that the angle can also be, for example, only 85 degrees or 80 degrees or even 95 degrees or 100 degrees, since the existence of a kink is important at which a change from the first part to the second part of the device occurs in the design of the device.

[0037] The first part 2 of the device 1 has two identically designed, but mirror-symmetrical anchoring units 5, which are Z-shaped in cross-section and each have a Z-shaped cross-section. One of each is arranged on a first structural part 6 and the other on an opposite, second structural part 7 separated by the joint, and is connected (screwed and / or glued) to the first structural part in a force-transmitting manner. A bridging unit 8 is arranged between the two anchoring units 5, which compensates for the length of a gap between the two anchoring units 5 that changes with the width of the joint 27. The two anchoring units 5 are made of an aluminum alloy and are manufactured by an extrusion process. The same applies to the bridging unit 8. Alternatively, the bridging unit 8 can also be made of a high-strength plastic material and be manufactured by extrusion.

[0038] The second part 3 of the device 1, which adjoins the first part 2 at an angle of 90°, also consists of two anchoring units 9 and a bridging unit 10 located between them and bridging the gap between the two aforementioned anchoring units 9. In this case, the bridging unit 10 consists of a plastic foam material in the form of an EPDM foam or PE foam. The two anchoring units 9 of the second part 3 of the device 1 are made of plastic, specifically PVC, and are manufactured by an extrusion process.

[0039] The strips 11 shown in Figure 1, which delimit a vertical section of the joint 27, serve merely to illustrate the vertical third and fourth vertical structural parts 12, 13, not shown in more detail in Figure 1, which extend over a considerably greater length than the strips 11 shown. From Figure 1 it can also be seen that horizontally aligned surfaces 14, 15 of the anchoring units 5 of the first part 2 of the device 1 form a right angle with corresponding surfaces 16, 17 of the anchoring units 9 of the second part 3 of the device 1. Looking at Figures 2a to 2c it can be seen that the anchoring units 5 of the first part 2 of the device 1 form a parallel to a surface 18 or 19 of the first orsecond structural part 6, 7 extending fastening leg 22 for connection to the respectively assigned structural part 6, 7, a support leg 23 extending at right angles thereto and a cantilever leg 24 again aligned at right angles to the support leg 23. The two cantilever legs 24 of the opposing anchoring units 5 have an undercut groove 25 into which an edge strip of the bridging unit 8 of the first part 2 of the device 1 engages, each edge strip ending with a rounded bend. The bridging unit 8 is displaceably mounted on both sides within the groove 25 in the cantilever leg 24 of the anchoring unit 9 in order to bridge changes in the width of the first, horizontally extending section 26 of the overall frame-shaped groove 27 between the adjacent structural parts.

[0040] A vertically aligned second section 28 of the groove 27 runs at a right angle to the horizontally aligned first section 26 of the groove 27. The groove 27 is overall frame-shaped, ie it has a horizontal section 26 in the floor area, two vertically running sections 28 in each wall area (one of which is not shown) and a second, horizontally aligned (again not shown) section in the ceiling area.

[0041] A vertically extending second section 27 of the joint 27, aligned with the horizontal first section 26, is bridged or covered by the second part 3 of the device 1. Figures 2a to 2c again show that the second part 3 of the device is composed of two anchoring units 9 and a bridging unit 10 made of a foam material, arranged between them and clamped with compressive stress. An anchoring unit 9, which is essentially C-shaped in cross-section, has a visible leg 29 facing the room, which is provided with an angled edge strip 30 at its free end facing the center of the joint.In addition, each anchoring unit 9 has a fastening leg 32 running at right angles to the visible leg 29 and parallel to a center plane 31 of the joint 27. The fastening leg 32 is provided with a toothing on the outside and forms a certain micro-positive fit with walls 33 of the second section 28 of the joint 27 due to the compressive stress in the bridging unit 10. The structural part 13 consists of a concrete part 34 and a plaster layer 35 or other wall covering applied thereto on the inside of the room. The anchoring units 9 are each supported by a short positioning leg 36 pointing away from the joint 27 on a surface 37 of the plaster layer 35. This prevents the anchoring units from being accidentally pushed too deeply into the joint 27.The bridging unit 10 of the second part 3 of the device 1, consisting of the foam material, is arranged under compressive prestress even in a state of the joint 27 in which its width 37 is at its maximum, and is thus securely arranged inside the two C-shaped anchoring units 9. If necessary, the bridging unit 10 can also be additionally secured against displacement parallel to the center plane 31 of the joint 27 by gluing it to the fastening legs 32 of the anchoring units 9.

[0042] While Figure 2b shows the state of the joint 27 and the device 1 in a "neutral state" ("zero state"), Figure 2c shows a state in which the width 38 of the joint 27 is minimal. In this case, the opposing anchoring units 5, 9 of both the first part 2 and the second part 3 of the device 1 abut against each other. In this case, the bridging unit 8 of the first part 2 almost completely fills the groove 25 formed in the cantilever legs 24.

[0043] The other extreme case is shown in Figure 2a, in which the joint 27 has a maximum width 38. In this joint state, angled edge strips on the bridging unit 8 of the first part 2 come into contact with oppositely angled (lower) cantilever legs 24 of the anchoring units 5. Even with smaller joint widths, the interlocking, angled edge strips prevent the bridging unit 8 from slipping out of the groove 25 in the cantilever leg 24.

[0044] In the present case, the width 38 of the joint 27 in its "neutral state" is 30 mm. Based on this, both a reduction and an increase in the width 38 by 6 mm each are possible, resulting in a minimum width 38 of 24 mm and a maximum width 38 of 36 mm. The first part 2 of the device 1 is designed to withstand loads from pedestrians and vehicles. If a vehicle drives over the first part 2, a load in the form of a linear load of 5 kg / mm ​​wheel width is possible, assuming a "hard roller."

[0045] Finally, Figure 1 shows that in each of the two parts 2, 3 of the device 1, four transition lines 39I, 39II, 40I, 40II, 411, 4111, 421 and 4211 are present, which on the one hand are formed by a transition from the cantilever legs 24 of the anchoring units 5 of the first part 2 of the device 1 to the bridging unit 8 of the first part 2 (transition lines 39I, 411), a transition from the cantilever legs 24 of the anchoring units 5 of the first part 2 to a surface 43 of a floor covering 44 (transition lines 40I, 42I) and on the other hand - on the side of the second part 3 of the device 1 - a transition from the visible legs 29 of the anchoring units 9 of the second part 3 to a surface above the bridging unit 10 of the second part 3 located open space 45 (transition lines 39II,41 II) and a transition from the positioning legs 36 of the anchoring units 9 of the second part 3 to the plaster layer 35 of the associated third building part 12 or fourth building part 13 (transition lines 40II, 42II).

[0046] Two horizontally extending lines 46 at the transition point 4 between the first part 2 and the second part 3 of the device 1 have the same length and correspond to the visible width of the respective anchoring units 5, 9. While this width for the anchoring units 5 is determined solely by the width of the cantilever legs 24, the visible width for the anchoring units 9 is composed of the width of the visible leg 29 and the width of the positioning leg 36. Furthermore, a width 47I perceptible to an observer between the transition lines 40I, 42I of the first part 2 of the device 1 corresponds to a perceptible width 47II between the transition lines 40II and 42II.For the observer of the device 1 in the installed state, the device 1 is therefore perceived as if the device 1 is constructed in a consistent manner both in the floor area and in the wall area (and possibly also in the ceiling area), which results in a particularly high aesthetic quality of the construction.
