Definitions
- the present invention relates to a bridging device for an expansion joint arranged between an abutment and a superstructure in a passable building, having the following features: on the abutment side and on the superstructure side, an edge profile is provided in each case; between the abutment and the superstructure, at least one lamella extending in the longitudinal direction of the joint is arranged, which is supported on at least two cross-members bridging the expansion joint, resting on the abutment and on the superstructure; on the upper side of the at least one lamella, a tooth profile is mounted, the teeth of which on both sides mesh sideways with the teeth of tooth profiles which are assigned to the adjacent edge profiles or lamellae; between the abutment-side edge profile and the adjacent lamella, the superstructure-side edge profile and the adjacent lamella and, if necessary, two adjacent lamellae, elastic sealing profiles are arranged, which are each detachably connected to the associated edge profile and the associated lamella or the two associated lamellae are
- Bridging devices as used in particular on road bridges to compensate for the particular caused by thermal expansion changes in the length of the superstructure, are known in different designs and in use.
- bridging devices with lamellae which are arranged within the joint gap between and parallel to the edges of the joints, are distinguished supported on the expansion joint bridging trusses, on the one hand and slat-free bridging devices on the other.
- Bridging devices with lamellae are particularly suitable for bridging expansion joints with a comparatively large working range (difference between maximum and minimum joint width).
- the tooth profiles attached to the lamellae reduce the noise generated when driving over the bridging device with motor vehicles by preventing the impact noises which occur in the case of bridging devices without tooth profiles (cf., for example, DE 8816536 U1) when the vehicle wheels hit the lamellae ,
- Gattungs ⁇ proper bridging devices for expansion joints are known, which are similar to the bridging devices described above, but differ from these by the fact that the tooth profiles are welded to the La ⁇ (see, eg, DE 19705531 C2 and WO 02/27102 Al).
- clamping profiles which are mounted laterally on both sides of the lamellae are used, into which the edges of the sealing profiles are inserted (see DE 19803004 A1).
- the object of the present invention is to provide a particularly reliable bridging device of the generic type which can be manufactured and installed with a particularly low technical and financial outlay.
- bridging devices according to the invention manage with a particularly small number of individual components and, to a greater extent, on standard components and / or relatively inexpensively producible, if necessary. modularly standardized components can fall back as this applies to generic ge bypass devices according to the prior art.
- a particularly advantageous embodiment of the present invention is characterized in that the sealing profiles are in the form of bump profiles (cf., DE 29907832 U1), with in each case at least 70% of the weight being assigned by the underlay of the sealing profile and the two being assigned Tooth profiles limited space below the bump section lie.
- the sealing profiles are essentially clamped over their entire length between the lamella and the tooth profile.
- Hier ⁇ under is to be understood that individual sections in which the sealing profile is not clamped between the lamella and the tooth profile - for example, due to a segmentation of the tooth profile with tolerance joints between the individual tooth profile segments (see below) - maxi ⁇ 10 mm are wide, wherein the ratio of such free sections to the total length of the Dichtungspro ⁇ fils along the joint is a maximum of 10%.
- the widths of the individual free sections of up to 5 mm can be realized without any problems in terms of technology, with a proportion of the overall length of the roofing profile of no more than 5%, better still no more than 2%.
- the sealing profile can be clamped reliably with a material-saving ge wrestling surface pressure. Even more important in practice is the complete or at least almost continuous covering of the edge region of the sealing profile, so that neither dirt nor moisture can penetrate there to a significant extent.
- the corresponding bridging device is therefore also characterized by increased reliability, since, according to that prior art, the edge of the sealing profile is in each case between two teeth, so that there are none Position securing the Dichtungs ⁇ profile is present and also dirt and moisture to a considerable extent can penetrate into the receptacle for the edge of the sealing profile. Such a tightness and thus reliability problem can be avoided in application of the present invention.
- the sealing profiles are fixed by means of their clamping according to the invention, in particular in the case of the arrangement of receiving grooves (in particular undercut) in which the edge regions of the sealing profiles are connected are added to the respective blade and clamped, despite the low installation costs particularly strong and thus be ⁇ especially "" reliable and ' durable ' ah ' the slats ' ange ⁇ can be connected.
- the at least one lamella has a substantially flat upper closure surface and the receiving grooves are bounded by recesses which are arranged on the underside of the tooth profile facing the lamella.
- the lamellae can be formed by inexpensive commercial standard components or rolled profiles, in particular HEM, IPE or comparable double T-carriers, which in view of the connection of the sealing profiles require no further post-processing.
- inventive bridging devices with tooth profiles detachably attached to the lamellae is characterized in that the tooth profiles are screwed to the lamellae, more preferably from above. It is particularly advantageous if the screws are mutually offset from the center of the respective blade (or the tooth profile) out, so that they are alternately particularly close to the two grooves, in which the edge regions of the attached to the relevant fin sealing profiles are clamped. Such an alternate lateral offset of the screws is for a load transfer of Forces acting on the tooth profiles in the lamella be ⁇ particularly favorable.
- the teeth of the tooth profile directed toward both sides are particularly preferably offset by half a pitch.
- the teeth arranged on the two sides of the tooth profile may overlap one another in the sense that the toothed feet are offset in each case from the center of the lamellae in the opposite direction from the associated tooth tips. This is particularly favorable with regard to the working range of the lock-up device.
- the tooth profile attached to the lamella can consist of a sequence of several individual, in particular identical, tooth profile segments whose length can correspond, for example, to 1-fold or, particularly preferably, 2-fold value of the pitch of the toothing. This may be advantageous, for example, insofar as in this case a damaged tooth profile segment can be renewed individually with little effort and within a very short time, which is particularly advantageous from the point of view of the least possible intervention in the traffic during pending wars work is advantageous. If, in this sense, the tooth profile is constructed as a sequence of individual tooth profile segments, then the impact between two adjoining tooth profile segments is particularly preferably oblique to the longitudinal direction of the lamella.
- the tooth profile or each of the tooth profile segments has a lower, applied to the La ⁇ melle, in particular strip-shaped currently- led base plate portion and an upper Zahn ⁇ plate portion.
- the width of the base plate section which has no serration, corresponds particularly preferably substantially to the width of the upper section of the lamella to which the tooth profile is attached; This is favorable both with regard to the static conditions as well as with regard to a reliable connection of the sealing profiles to the slats.
- the base plate section on the one hand and the toothed plate section on the other can be produced separately and joined together to form the corresponding tooth profile, in particular welded together, or the corresponding tooth profile is formed, for example by forging or machining - one-piece.
- the pitch of the toothing is between 0.8 times and 1.5 times the value of the width of the lamella, with the toothing particularly preferably being substantially sinusoidal or triangular with rounded Zahnspit ⁇ zen and rounded tooth feet is performed. This results in particularly favorable static conditions with, at the same time, particularly low noise development when driving over the bridging device with a vehicle.
- the statement that the receiving grooves should be "sideways" should not be limited to the fact that the receiving grooves are designed such that the sealing profiles in the region of the openings of the receiving grooves more or less less hori zontal run; Rather, the sealing profiles of the receiving grooves in the region of the openings may also more or less inclined, in particular downwardly inclined ge emerge, if this appears to be favorable in the individual case, for example, when the base column portion of the tooth profile protrudes laterally beyond the lamella.
- FIG. 2 shows a plan view of a lamella with two tooth profile segments of the overbridging device according to FIG. 1 and screwed onto it
- FIG. 3 shows, in a larger context in a vertical section, the bridging device illustrated in FIG. 1 '.
- the expansion joint D has a respective edge profile R on the bearing side and on the superstructure side, respectively - anchored there in a known manner.
- a plurality of extending in Fu ⁇ genlteilscardi lamellae 2 are arranged, which are also supported in such known manner on two bridging the expansion joint, resting on the abutment and the superstructure Tr Tr.
- the slats 2 are each designed as HEM supports with an upper flange 3, a web 4 and a lower flange F (shown only in FIG. 3).
- each toothed profile segment 9 is screwed onto the upper flange 3 of each lamella 2, ie each tooth profile segment by means of four screws 10, which are arranged in a corresponding threaded bore arranged in the upper flange 3 ments 11 are screwed.
- the screws 10 are arranged offset mutually from the center 12 of the tooth profile 6 out.
- the teeth 7 on one side of the tooth profile 6 are offset by half a pitch T with respect to the teeth 8 on the other side of the tooth profile.
- the teeth 7 and 8 overlap on the two sides of the tooth profile 6 to each other in the sense that the tooth bases 13 are each offset processing in the opposite Rich ⁇ from the center 12 of the ⁇ lamellae "2" as the associated teeth tips fourteenth
- Each tooth profile segment 9 has a lower abutment against the upper flange 3 of the associated lamella 2.
- the essentially strip-shaped base plate section 15 and an upper tooth plate section 16 laterally delimited by the two toothings.
- the width of the base plate section 15 corresponds to the width of the upper flange 3 of the adjacent lamella 2.
- the tooth profile segments 9 on the underside of the base plate sections 15 have two recesses 18 arranged adjacent to the side edges.
- the sealing profile 22 is designed as H ⁇ ckerprofil. It comprises a beam 23 formed from two essentially V-shaped zueinan ⁇ arranged legs and a hat-shaped bump portion 24.
