[0002] Device for bridging an expansion joint formed between floor sections of a building
[0003] Technical field
[0004] The invention relates to a device for bridging an expansion joint formed between floor sections of a building, comprising at least two bridging units whose mutually facing edge sides are designed to be complementary to each other in such a way that they interlock, each edge side having alternating wave crests and wave troughs. The invention also relates to the use of such a device.
[0005] State of the art
[0006] Stress cracks can occur in a continuous floor of a building due to shrinkage, thermal expansion, thermal shrinkage, moisture absorption, and creep caused by loads. To prevent this, an expansion joint is conventionally installed between sections of the floor, allowing for limited movement of the floor sections relative to each other.
[0007] The larger an expansion joint is, the more problematic it becomes to drive over it with a vehicle, such as a forklift in a warehouse. Driving over the expansion joint can damage both vehicle wheels and the adjacent edges of the floor sections, both of which should be avoided. Furthermore, driving over a large expansion joint can make the operation of a vehicle unsafe.
[0008] For these reasons, an expansion joint is conventionally bridged with a device such as that known from WO 2013 / 057 299 A1. This device has two bridging units whose facing edge surfaces are designed to be complementary to each other, interlocking, with each edge surface having alternating wave crests and troughs. Tebroke, Anselm TBR006PWO - 2 -
[0009] Disclosure of the invention
[0010] One object of the invention is to provide a more robust and durable device of the type mentioned above.
[0011] This problem is solved by the independent patent claims. Advantageous embodiments are described in the dependent patent claims, the following description, and the figures, whereby these embodiments, either individually or in combination with at least two of them, can represent an advantageous and / or further developing aspect of the invention.
[0012] A device according to the invention for bridging an expansion joint formed between floor sections of a building has at least two bridging units, the mutually facing edge sides of which are designed to be complementary to each other in such a way that they interlock, wherein each edge side has alternating wave crests and wave troughs and wherein a width of the respective wave crest and / or wave trough corresponds to at least five times an amplitude of the respective wave crest and / or wave trough.
[0013] The device according to the invention, which can also be called a bridging device, in particular an expansion joint bridging device, thus has bridging units with a novel edge geometry. This is advantageous compared to a conventional edge geometry, such as that known from WO 2013 / 057 299 A1, since the wave crests of the edge surfaces according to the invention are quite large and robust compared to the wave crests of a conventional edge geometry, thereby significantly increasing the load-bearing capacity of the wave crests according to the invention and thus the overall robustness of the device according to the invention.With the typically finger-like wave crests of a conventional edge geometry, material fatigue can quickly lead to the breakage of a wave crest over time, thereby compromising the desired safe crossing of a bridged expansion joint and necessitating replacement of the damaged bridging unit. In contrast, with the broad wave crests of the edge geometry according to the invention, such breakage of wave crests is prevented (si-Tebroke, Anselm TBR006PWO - 3 -).
[0014] This can be avoided permanently and reliably. As a result, the device according to the invention is significantly more durable than a conventional bridging device, which above all saves costs for the aforementioned replacement of bridging units.
[0015] The device according to the invention is preferably designed and can be arranged on a floor such that the mutually facing edge sides always interlock, regardless of the size or width of the expansion joint being bridged. This ensures that the device according to the invention, and thus the expansion joint it bridges, can always be driven over safely and without impact.
[0016] The wave crests and troughs of each edge can be arranged in a periodic or aperiodic alternating pattern. The wave crests and / or troughs of each edge can be identical or different.
[0017] According to the invention, the width of each wave crest and / or trough is at least five times its amplitude. The advantage described above increases with a larger ratio of crest width to amplitude. Therefore, the width of each wave crest and / or trough can, for example, be greater than seven or nine times its amplitude.
[0018] At least one of the opposite edges of the bridging units can, for example, be straight or have alternating crests and troughs. The edge can, for instance, have a sinusoidal shape, or the crests and / or troughs of the edge can be triangular, quadrilateral, or trapezoidal. For example, the edge can be shaped like the edge of the bridging unit facing the other bridging unit. By shaping the edge of each bridging unit facing away from the other with crests and troughs, a straight gap between a floor section and the attached bridging unit can be prevented.This occurs when the bridging unit, as described below, is moved towards the other bridging unit during readjustment. By avoiding a corresponding straight gap between the floor section and the bridging unit, Tebroke, Anselm TBR006PWO - 4 -.
[0019] Safe and shock-free passage over the device must be ensured.
[0020] The device according to the invention can, for example, be used to bridge an expansion joint between floor sections of a building designed as a warehouse. In principle, however, the device according to the invention can be used to bridge any expansion joint between floor sections, without being limited to a specific type of floor or building.
[0021] According to an advantageous embodiment, at least one bridging unit has at least one upper bridging profile that forms at least part of a top surface of the bridging unit. The bridging profile has at least two elongated holes spaced apart from each other in the longitudinal direction of the bridging unit and extending in the lateral direction of the bridging unit. This allows the distance between the bridging units or their bridging profiles to be subsequently varied, in particular reduced. This may be necessary if the bridged expansion joint has increased significantly over time, for example, due to shrinkage. Subsequent reduction of the distance between the two bridging units or bridging profiles makes it possible to keep this distance as small as possible to ensure safe and impact-free passage over the device.to permanently bridge the expansion joint. This requires no replacement of parts of the device or the entire device. Furthermore, the installation effort for reducing the gap between the bridging units or bridging profiles is relatively low. Only two fastening screws inserted through the elongated holes of each bridging profile need to be loosened, after which the bridging profile can be moved towards the other bridging profile. Finally, the fastening screws can be tightened again. Alternatively, each of the two bridging units can have its own bridging profile with corresponding elongated holes.
[0022] According to a further advantageous embodiment, each elongated hole has a lower through-pass section through which a shank of a fastening screw can be passed, and a receiving section adjoining the through-pass section and opening into the top of the bridging unit, in which a Tebroke, Anselm TBR006PWG - 5 -
[0023] The head of the fastening screw is at least partially receptive, with the receiving section being larger than the through-section in both the longitudinal and lateral directions of the bridging unit. This allows the head of the respective fastening screw, which is provided with a drive contour, to be partially or preferably completely countersunk into the receiving section of the respective elongated hole, further improving the device's traversability. When the fastening screw is tightened, an underside of the screw head rests on a shoulder, over which the receiving section transitions into the smaller through-section of the respective elongated hole.
[0024] According to a further advantageous embodiment, the bridging unit has at least one load-bearing profile that is rigidly connected to a lower side of the bridging profile facing away from the upper side of the bridging unit. This load-bearing profile has elongated holes that are aligned with one of the elongated holes of the bridging profile and are shaped according to the penetration section of the respective elongated hole of the bridging profile. The load-bearing profile reinforces the bridging profile and thus makes the bridging unit even more robust. The load-bearing profile is preferably designed and arranged on the bridging profile such that it does not project beyond the edge of the bridging unit or the bridging profile that faces the other bridging unit. The load-bearing profile can be made of the same material as the bridging profile or of a different, in particular harder, material.It should be made of a more dimensionally stable material.
[0025] According to a further advantageous embodiment, the load-bearing profile is bonded to the bridging profile by means of a material bond. This eliminates the need for mechanical components and the associated assembly work. The load-bearing profile can, for example, be bonded to the bridging profile.
[0026] According to a further advantageous embodiment, at least one bridging unit has at least one bearing profile that can be immovably attached to one of the base sections and which, forming a sliding bearing, contacts an underside of the load-bearing profile facing away from the bridging profile. The bridging profile or a combination of the bridging profile and the load-bearing profile Tebroke, Anselm TBR006PWG - 6 -
[0027] The assembled component can slide on the bearing profile, for example, to allow for the subsequent adjustment of the device as described above. The bearing profile can be made of the same material as the load-bearing profile and / or the bridging profile, or of a different material.
[0028] According to a further advantageous embodiment, through holes are formed in the bearing profile through which the shank of the fastening screw can be guided, and which are each aligned with one of the elongated holes. In this case, the fastening screw can thus be guided through the entire bridging unit in order to secure or fasten all components of the bridging unit to a floor section with this fastening screw.
[0029] According to a further advantageous embodiment, the device has at least two fastening screws that can be passed through the elongated holes of the at least one bridging profile. The bridging profile can be attached or anchored to at least one of the base sections via these fastening screws. Each fastening screw can have a screw head that can be dimensioned such that it can be arranged largely or completely within a receiving section of an elongated hole in the bridging profile.
[0030] According to a further advantageous embodiment, the device comprises at least one anchor rail attachable to the base sections and at least one special screw unit by means of which one of the bridging units can be attached to the anchor rail in various positions relative to the anchor rail with respect to its longitudinal extent, wherein the anchor rail is arranged transversely to a longitudinal extent of the device and wherein at least one through-hole is formed in the bridging unit through which a section of the special screw can be passed. This allows the distance between the bridging units to be subsequently varied, in particular reduced, which may be necessary if the bridged expansion joint has increased considerably over time, for example due to shrinkage.Subsequent reduction of the distance between the two bridging units makes it possible to keep this distance as small as possible in order to ensure safe and shock-free driving over the device or the expansion joint it bridges (Tebroke, Anselm TBR006PWO - 7 -).
[0031] to enable permanent installation. This requires no replacement of parts of the device or the entire device. Furthermore, the assembly effort for reducing the distance between the bridging units is relatively low. Only the special screw unit, which is inserted through the through-hole of the respective bridging unit, needs to be loosened, after which the bridging unit can be moved towards the other bridging unit. Finally, the special screw unit can be tightened again. Advantageously, at least one through-hole can be provided on each bridging unit, through which a special screw unit can be inserted, in order to attach both bridging units to the same anchor rail.Advantageously, the device can have at least two anchor rails arranged parallel to each other and spaced apart along the longitudinal extent of the device, to which the respective bridging unit can be attached. The respective anchor rail can, for example, have a C-shaped cross-sectional area. The respective anchor rail can, for example, be made partially or completely of a metal or a metal alloy. The respective special screw unit can, for example, comprise a hammerhead bolt, the head of which can be guided in the anchor rail, and a nut that can be screwed onto the hammerhead bolt and bears against a side of the bridging unit facing away from the anchor rail. The nut can preferably be arranged in a recess on a top surface of the bridging unit.Alternatively, the special screw unit can have a nut, for example a substantially cuboid-shaped one, guided in the anchor rail, and a countersunk screw that can be screwed into it, the head of which can be supported on a side of the bridging unit facing away from the anchor rail. The head of the countersunk screw can preferably be arranged in a recess on a top side of the bridging unit.
[0032] According to a further advantageous embodiment, at least two vertical through-holes are formed on at least one bridging unit, which are spaced apart from each other in the longitudinal direction of the bridging unit, wherein the device has at least two eccentric fastening screws which can be passed through the vertical through-holes of the at least one bridging unit, such that an eccentric section of the respective eccentric Tebroke, Anselm TBR006PWG - 8 -
[0033] The fastening screw is at least partially located within the respective vertical through-hole. By rotating the eccentric fastening screws inserted into the vertical through-holes of the bridging unit, the position of the bridging unit relative to the other bridging unit can be varied, in particular to adjust and readjust any gap between the bridging units, preferably to a minimum. Both bridging units can also have corresponding vertical through-holes, with the number of eccentric fastening screws of the device preferably corresponding to the number of vertical through-holes of the device.
[0034] According to a further advantageous embodiment, the device has at least one edge profile that can be arranged on one side of one of the bridging units, opposite the respective other bridging unit, wherein the facing edge sides of the edge profile and the adjacent bridging unit are designed to be complementary to each other such that they interlock, and wherein each edge side has alternating wave crests and wave troughs. During assembly of the device, the width of a joint between the edge profile and the base section and the width of a joint between the edge profile and the adjacent bridging unit could be set to zero.If readjustment of the device is required later to reduce the width of the joint between the bridging units, the width of the joint between the edge profile and the bridging unit can be increased, for example, by half the width of the joint between the two bridging units. Due to the special shape of the facing edges of these components, the resulting joint between the edge profile and the bridging unit can also be traversed safely and without impact. The device can, for example, also have two such edge profiles, between which the bridging units can be arranged, thus giving the device three joints with adjustable widths.
[0035] According to a further advantageous embodiment, at least one bridging unit and / or at least one edge profile is formed entirely from a glass fiber reinforced plastic. This allows the bridging unit or the edge profile to be Tebroke, Anselm TBR006PWG - 9 -
[0036] After on-site installation, the bridging unit or edge profile is ground down from above to easily match the surface level of the adjacent floor section. This would not be as straightforward if the bridging unit or edge profile had additional reinforcement, such as metallic reinforcement. Therefore, in this advantageous design, the bridging unit or edge profile is reinforcement-free. The bridging unit can be a single, monolithic piece or comprise two or more components, such as the bridging profile, the load-bearing profile, and / or the bearing profile, each made of glass fiber reinforced plastic. Furthermore, the use of glass fiber reinforced plastic allows for simple and cost-effective production of the bridging unit or edge profile in various sizes.Each bridging unit or edge profile can also be made from a glass fiber reinforced material.
[0037] According to a further advantageous embodiment, the edge of the respective bridging unit and / or the edge of the edge profile has a sinusoidal shape, or the wave crests and / or troughs of the edge are triangular, quadrilateral, or trapezoidal. By selecting the appropriate shape for the edge of the bridging units or edge profiles, the device can be optimally adapted to the specific conditions and requirements. Alternatively, various combinations of at least two of the aforementioned wave crest shapes are also possible for the shape of the edge of the bridging units or edge profiles.
[0038] According to a further advantageous embodiment, projections and recesses are formed on each of the mutually facing edge sides of the bridging units, such that the projections of one edge side engage in the recesses of the other edge side, the projections and recesses being dimensioned many times smaller than the wave crests and troughs. This further improves the smooth traversability of the device. The projections or recesses can each be, for example, trapezoidal, triangular, or quadrilateral. A rounded embodiment of the Tebroke, Anselm TBR006PWQ - 10 - is also possible.
[0039] Projections or recesses are possible, for example a semicircular or semi-elliptical design.
[0040] The invention further proposes the use of the device according to one of the above-mentioned embodiments or a combination of at least two of these embodiments to bridge an expansion joint formed between floor sections of a building.
[0041] The advantages mentioned above with reference to the device are correspondingly associated with its use.
[0042] The invention is explained below by way of example with reference to the attached figures and preferred embodiments, whereby the features explained below can represent an advantageous and / or further developing aspect of the invention both individually and in different combinations with one another.

[0061] No mechanical fasteners are required for bridging units 2 and 3 to the respective floor section. After proper installation or fastening of the device 1 to the floor, the respective bridging unit 2 or 3 can be sanded from above to remove material, thus easily adapting its top surface to the level of the top of the adjacent floor section.
