Description

Austrian Patent Office AT511 194 B1 2012-10-15

The invention relates to a device for bridging an expansion joint in a roadway, in particular in the transition region to bridges, comprising a mat-shaped intermediate profile with a length 1, wherein the intermediate profile over the length 1 is divided into a plurality of profile pieces extending in the longitudinal direction of the intermediate profile, wherein the individual profile pieces are connected to form a watertight connection with each other, wherein the watertight connection is formed in the joint area of two adjacent profile pieces by a butt lock, including clamp members are arranged, are mechanically connected to each other via the two adjacent profile pieces, as well as an expansion joint in a roadway in the transition area to a bridge.

On roads, it is known to provide an expansion joint in the transitional area of the roadway to a bridge in order to bridge the changes in length of the bridge resulting from dynamic loads imposed by traffic, temperature fluctuations, shrinkage and creepage. In the prior art there are different constructions for the formation of such expansion joints.

For example, in a so-called finger transition of the joint gap bridged by cantilevered fingers of two finger plates, the fingers are arranged intermeshing. The finger elements are bolted to a cast-in steel substructure.

In single-profile transitions length changes are made possible by an attached between two steel profiles elastomer profile. The profile is fastened by means of clamping flanges in the steel edge girders, whereby these transitions are watertight.

In a multi-profile transition, the total joint gap is divided by transverse to the roadway running (steel) profiles (slats) in several single joint gaps. These single joint gaps are sealed against water and dirt by sealing profiles made of elastomer, which are knotted into the lamellae. The slats are slidably mounted on trusses.

The basic elements of Rollverschlussdehnfugen form plates that slide on a gantry.

In so-called mat transitions mats can be offset with composite anchors directly on a concrete bed, the mats are linked to the composite anchors. There are mat designs that have hollow channels and possibly a surface profiling, whereby the mat can absorb strains and compressions better.

From FR 2 641 012 A1 a device for bridging an expansion joint for roads is known which comprises two lateral metallic strips and, in between, an expansion element made of an elastomer having a W-shaped cross-section. This device consists in the longitudinal direction of the expansion joint of several successively arranged profile elements. Between the profile elements, sealing strips are arranged, which are connected to the profile elements by means of projecting ribs which engage into corresponding, undercut grooves of the profile elements.

From GB 1 419 420 A, a device for bridging an expansion joint for roads is also known, which consists of a plurality of successively arranged profile elements in the longitudinal direction of the expansion joint. In the joint area, the profile elements have a projecting rib or a corresponding groove. The rib and the groove have a triangular cross-section.

It is the object of the present invention to provide an improved mats transition available.

This object is achieved on the one hand with the aforementioned device and on the other hand with the expansion joint mentioned above, wherein in the device in the joint areas between two adjacent profile pieces each arranged an adhesive element 1/15 Austrian Patent Office AT 511 194 B1 2012-10-15 is, are glued to each other via the two adjacent profile pieces, wherein the clamping elements and / or the adhesive elements are each formed integrally with the profile pieces, and wherein the expansion joint comprises this device.

Although the disadvantage is connected by the division of the intermediate profile to a plurality of profile pieces in comparison to the aforementioned lamella design that over the course of the longitudinal extension of the expansion joint one or more impact areas between the profile pieces are present, is formed by this design of the device or the Expansion joint of this disadvantage achieves the advantage that thus the production of the intermediate profile can be made easier, especially if they are produced by press vulcanization, since the corresponding devices can be made shorter for this purpose. This shortening also has the advantage that over the length of the profile pieces and thus in total over the entire length of the intermediate profile a more uniform property profile of the intermediate profile can be provided. Moreover, by shortening the handling of the intermediate profile, i. the profile pieces, during assembly, its transport and storage easier.

In the joint areas, in each case an adhesive element is arranged between two adjoining profile pieces, are glued to each other via the two adjacent profile pieces. Due to the additional arrangement of this adhesive element, the clamping element can be relieved or the strength of the connection can be increased. In addition, thus the water resistance of the joint area can be further improved. But it is also possible that this type of training the shock lock is provided alone, especially when the shock area is subject to less stress, for example in walking or cycling, in which the proportion of the dynamic load caused by traffic compared to lanes with motor vehicle traffic is reduced. It should be noted, however, that the exclusive adhesive bond may be sufficient even in areas with motor vehicle traffic with appropriate choice of the adhesive or the geometry of the adhesive bond.

The clip elements and / or the adhesive elements are each formed integrally with the profile pieces, which on the one hand, the manipulation effort can be reduced on the site, and on the other hand, no additional connection areas for connecting the clip elements and / or the adhesive elements with the respective profile pieces are required.

In order to enable the absorption of higher forces by the device and to further improve the watertightness, it is provided that the watertight connection is formed in the joint area of two adjoining profile pieces by a shock lock.

It is envisaged that in the joint areas between two adjacent profile pieces to form the shock locking clip elements are arranged, are mechanically connected to each other via the two adjacent profile pieces. It is thus on the one hand a solid, permanent connection of the professional pieces achieved with each other, on the other hand, the elasticity of the intermediate profile is not or only slightly affected. By this type of connection, a long service life of the device can be achieved without increased maintenance.

According to a preferred embodiment, a clip element has a first profile element (a so-called female profile) and a second profile element (a so-called male profile), wherein the first profile element has a recess and the second profile element has a profile section with a cross section of the recess having corresponding cross section. It is thus achieved that the mechanical connection can be made in the manner of a tongue and groove connection between the two profile elements by receiving the male profile of the recess of the female profile, whereby the assembly and connection of the individual profile pieces of the intermediate profile can be simplified. In addition, so that the pull-out strength of the compound can be improved. In the preferred embodiment, the first profile element is arranged on one of two adjoining profile pieces and the second profile element on the other of the two adjoining profile pieces. It is thus possible that the clamping of the profile pieces can be formed by simply pressing the male profile into the female profile, so that the individual profile pieces can already be placed correctly oriented to each other, without these for the preparation of the compound further manipulation with respect to their relative position to each other require.

According to the preferred embodiment, it is provided that the adhesive element consists of two profile elements, wherein in each case a profile element is arranged on each one of two adjacent profile pieces, and the two profile elements are arranged one above the other, whereby the formation of the adhesive connection can be simplified.

It may further be provided that the impact lock viewed in front view of the intermediate profile has at least one rising in the direction of the impact between two profile pieces and at least one sloping region. Through this "undulating " Course over the width of the intermediate profile, ie in the direction of the impact between two profile pieces, a better distribution of the forces acting on the intermediate profile forces can be achieved.

In the preferred embodiment of the device, the intermediate profile on at least one expansion element, so that the intermediate profile can absorb higher expansion and compression forces.

Particularly preferred in this case, the expansion element considered in front view of the intermediate profile on a W-shaped course. Compared to conventional "V-systems" can thus be achieved a reduction in the height of the device, causing this u.a. also suitable for renovation purposes. In addition, it could be observed that this profiling of the expansion element has advantages with regard to the noise development during crossings. In addition, a lower reliability can be achieved by the lower height. In conventional V-shaped expansion elements whose vertical extent is so large that the expansion element protrudes partially into the underlying open expansion joint. Excessive loads caused by the bridge pose the danger that the gap, ie the expansion joint, almost completely closes or narrows. Although this is at least partially remedied by adjusting the geometry of the gap design, in particular this gap narrows in the direction of the roadway in order to avoid the "overpressure" effect. to avoid the expansion joint through the bridge. Nevertheless, with a V-shaped expansion element, due to the larger vertical dimension, this expansion element may be pinched and ultimately sheared off at high pressure exerted by the bridge. Due to the lower height of the expansion element according to the invention this problem is better taken into account.

According to another embodiment of the device is provided that the profile pieces have a maximum length of 1.5 m. It is thus possible that these profile pieces are manipulated manually, whereby their installation on the construction site can be performed easily without a crane. In conjunction with the above-described possibilities for forming the butt lock, a high fatigue strength and a high watertightness of the device is achieved despite the associated higher number of connecting regions over the length of the intermediate profile.

According to one embodiment of the expansion joint is provided that the mat-shaped intermediate profile is bonded at least approximately over the entire surface with the support surface, whereby the structural strength of the expansion joint can be improved.

It is also possible that the expansion joint is wave-shaped, whereby the ride comfort during the crossing can be improved. In addition, the noise development during the crossing can be reduced.

For a better understanding of the invention, this is explained in more detail with reference to the following figures 3/15 Austrian Patent Office AT511 194 B1 2012-10-15.

In each case in a greatly simplified schematic representation: [0028] FIG. 1 shows an expansion joint cut in front view with a built-in inter mediate profile for bridging the expansion joint; FIG. 2 shows a profile piece of the intermediate profile in side view; FIG. FIG. 3 shows the profile piece according to FIG. 2 in plan view; FIG. FIG. 4 shows a detail of a first front end region of the profile piece according to FIG. 2; FIG. FIG. 5 shows a detail of a second front end region of the profile piece according to FIG. 2; FIG. FIG. 6 shows a detail of a cross section through the profile piece according to FIG. 2; FIG. Fig. 7 is an expansion element in cross section.

By way of introduction, it should be noted that the positional information chosen in the description, such as. top, bottom, side, etc. related to the immediately described and illustrated figure and to be transferred to a new position analogously to the new situation.

In Fig. 1 the installation situation of a device 1 for bridging an expansion joint 2 in this expansion joint 2 is shown. The expansion joint 2 is formed between two roadway sections 3, 4, in particular in the transition region from a roadway to a bridge. In general, however, the device 1 is also suitable for other bridging of expansion joints 2 in road traffic, for example, for expansion joints 2 in the course of sidewalks or in the range of Schrammborden.

The two roadway sections 3, 4 have the usual structure for this purpose.

The device 1 comprises or consists of a mat-shaped intermediate profile 5, preferably at least one metal insert 6, in the illustrated embodiment, two metal inserts 6 are provided.

The intermediate profile 5 consists in particular of a rubber, preferably EPDM, although other types of rubber come into question, which have the desired mechanical characteristics. But there are also combinations of materials, especially with plastics, usable.

The at least one metal insert 6 is preferably made of a steel, but may also consist of other metals or metal alloys. This metal insert 6 is used inter alia. the mechanical connection or anchoring of the intermediate profile 5 to the road substructure or to the expansion joint 2 provided support elements 7, 8, in particular so-called concrete beds or concrete blocks or strips, the left and right, leaving an intermediate gap 9 arranged in the expansion joint or ., are formed, provided that the pull-out strength of the intermediate profile 5 for a screw connection or composite anchor 10, 11 is not sufficient. In addition, the metal insert 6 can also exert a reinforcing function in the intermediate profile 5. Preferably, the metal insert 6 is formed by an angle profile strip 12, 13 with at least approximately right angles, the angled portion 14, 15 in an edge region 16, 17, which is at least approximately parallel to a longitudinal end face 18, 19 of the intermediate profile 5 (Figure 3). is arranged. Furthermore, the metal insert 6 has at least one opening 55 for the passage of the composite anchors 10, 11.

As already mentioned, the metal insert 6 is preferably embedded in the intermediate profile 5. For this purpose, this intermediate profile can be produced by press vulcanization of a rubber in a mold, wherein in advance the metal insert 6 is inserted into the mold, so that it is enclosed by the rubber. However, there is also the possibility to realize the embedding of the metal insert 6 in the intermediate profile 5 by a anderwärtiges method. In addition, there is the possibility of arranging the metal insert 6 on the outside of the intermediate profile 5, for example by screwing or by molding, wherein additionally in the metal insert 6 recesses or openings can be provided by the Austrian Patent Office AT511 194 B1 2012-10-15 the rubber of the intermediate profile 5 are at least partially penetrated or into which the rubber of the intermediate profile 5 at least partially penetrates.

Preferably, the metal insert 6 is at a small distance from a bottom surface 20 of the intermediate profile 5, which points in the direction of the support elements 7, 8, arranged therein. For example, this distance may be between 5% and 30% of a height 21 (FIG. 21) of the intermediate profile 5 in the direction perpendicular from above onto the expansion joint 2 (viewed in the installation position of the intermediate profile 2).

However, it is also possible to design the metal insert 6 differently, for example as a flat profiled strip, as round rods, as fibers, in particular metal fibers, etc., but angled embodiments have a better pull-out strength of the intermediate profile 5 in comparison to a flat material.

The support elements 7, 8 are, as already mentioned, preferably made of a, in particular reinforced, concrete. The support elements 7, 8 are in the expansion joint 2 so situated that a road surface 22, 23 is partially disposed thereon. For this purpose, the support elements 7, 8 may be executed stepped on the side facing away from the expansion joint 2, in order to achieve an at least approximately level-level connection to the device 1 and the expansion joint 2.

The intermediate profile 2 has a length 1 which corresponds at least approximately to the length of the expansion joint 2. About this length 1, the intermediate profile 5 is divided into several profile pieces 24. Such a profile piece 24 is shown in Figs. 2 to 7 in different views and sections. The profile piece 24 may be planar, in particular mat-shaped, executed. It preferably has a length 25 which is at most 1.5 m, in particular at most 1 m. A width 26 of the profile piece 24 may correspond at least approximately to the width of the expansion joint 2 (FIG. 1) between the two roadway sections 3, 4 (FIG. 1), it being by at least approximately meant that, as shown in FIG , a connection region 27 between the intermediate profile 5 and the respective road surface 22, 23 may be poured with a conventional potting compound 28. To bridge at least approximately the entire expansion joint 2, so for example the entire bridge width, several of these profile pieces 24 are arranged one behind the other and connected to each other, wherein the connection is made waterproof.

The waterproof connection of two adjoining profile pieces 24 is preferably designed as a shock lock. For this purpose, a clip element 30 and / or an adhesive element 31 can be provided in the joint regions between in each case two adjoining profile pieces 24 on end faces 28, 29 opposite each other in the direction of the length 25 of the profile pieces 24. About the clamp member 30 is thereby a mechanical lock and the adhesive member 31 is a "chemical lock". achieved by gluing the two profile pieces 24.

A preferred clip element 30 comprises a first or consists of a first profile element 32 (female profile) and a second / a second profile element 33 (male profile), wherein the first profile element 32 has a recess 34 and the second profile element 33 has a profile section 35 having a cross-section of the recess 34 corresponding cross-section. For example, the recess 34 of the first profile element 33, so the female profile, have a cylindrical cross-section. The profile section 35 of the second profile element 33, ie the male profile, is therefore likewise provided with a cylindrical cross section, so that the male profile can be received by the female profile and thus the mechanical locking of the impact area is produced. The male profile can in principle be formed in the profile section 35 at least approximately rod-shaped. In a particular embodiment of the clamp element 30, however, the two profile elements 32, 33 have the same cross section, as shown in FIGS. 4 and 5. The detail of FIG. 4 shows the male profile. Due to the approximately hollow cylindrical design of the profile element 33 of this "hollow cylinder" can be. On the one hand, on the underside 36, on the one hand, the function of the male profile and, on the other hand, the function of the female profile can be assumed on an upper side 37. For this purpose, the profile element 33 (male profile) of a first profile piece 24 are pressed into the profile element 32 (female profile) of a second adjoining profile piece 24 for producing the mechanical locking. For this purpose, the two profile pieces 24 placed on blocks and with a shock locking device, for example in the form of a pair of pliers, which has the contour of the profile elements 32, 33, are pressed together.

By the term "approximately hollow cylindrical". is meant that the formation of the recess 34, a hollow cylindrical design with a closed circumference is not possible. In addition, the recess 34 is flanked on the right and / or left side surfaces 38, 39, as shown in Figs. 4 and 5, respectively. A width of the side surfaces 38, 39 in the direction of a longitudinal central axis 40 may be, for example, up to a maximum of 5 cm.

The slot defined by the recess 34 for insertion of the male profile of the profile element (s) 32, 33 preferably has a width 41 in the direction of the longitudinal central axis 40, which is smaller than a maximum diameter 42 of the recess 34. It is Thus, a higher strength of the mechanical locking achieved because the male profile, whose diameter substantially corresponds to the maximum diameter 42 of the female profile, must be pressed through this slot. It is advantageous if the material thickness of the impact lock in this area a maximum of 30%, in particular between 5% and 20%, the height 21 of the profile piece 24 to facilitate the bending of the female profile in the region of this slot during the pressing of the male profile However, this wall thickness should not be too low in view of the strength of the lock.

The profile elements 32, 33 may be arranged on the profile pieces 24 such that the profile element 32 (female profile) below or from below to an imaginary center plane 43 through the profile piece 24 reaching (viewed in the direction of a lower support surface 44 ) are arranged on the left in Fig. 3 end face 28 and the second profile element 33 (male profile) above or from above to the imaginary center plane 43 through the profile piece 24 at the right in Fig. 3 end face 29.

This embodiment of the clip elements 30 has the advantage that all profile pieces 24 can have the same shape, so that therefore not several different shaped parts, i. Profile pieces 24, must be made. It should be noted, however, that it is possible in principle in the context of the invention that a first profile piece 24 on the two end faces 28, 29 only male profiles and a second profile piece 24 on the two end faces 28, 29 only female profiles. In addition, it is possible that the profile pieces 24 have only male profiles or female profiles and the respective corresponding female profiles or male profiles are arranged on a separate profile piece forming a type of clip. This clip may also consist of a different material to the material of the profile pieces 24, for example a metal, especially steel.

Although in view of the compressibility of the two profile elements 32, 33 of the clip member 30 is given a rounded cross-sectional shape of the male and female profile preference, so for example, at least approximately circular or oval, there is in principle the possibility that this other Have cross-sectional shapes, for example, quadrangular (square or rectangular), pentagonal, hexagonal, octagonal, polygonal, etc. The above statements are applicable to these other cross-sectional shapes accordingly.

It should also be mentioned that, although preferably all the profile pieces 24 have the same shape, but it is possible that e.g. the two end pieces of the intermediate profile 5, which are only connected to a further profile piece 24, only at one of the two end faces 28, 29 are formed with the respective profile element 32 or 33.

The impact lock may alternatively or in addition to the clamp member 30, the adhesive member 31 have. The adhesive element 31 comprises or consists of two profile elements 45, 46, wherein the first profile element 45 is arranged on in each case one of two adjoining profile pieces 24, and the second profile element 46 on second profile piece 24 of the two adjoining profile pieces 24, so that the two profile elements 45, 46 are arranged one above the other at the two interconnected profile pieces 45. In other words, this means that the first profile element 45 is arranged in the lower part of the impact lock with respect to the center plane 43, for example on the right end side 29 in FIG. 3, and the second profile element 46 in the upper part with respect to the center plane 43 For example, the two profile elements 45, 46 may each have the shape of a half-shell, so that they define a hollow cylinder in the connected state of two profile pieces 24. In general, however, these two profile elements 45, 46 may have a different cross-sectional shape, for example, oval, triangular, quadrangular, pentagonal, hexagonal, etc., executed, but in any case the two profile elements 45, 46 in the finished shock lock a cavity or a Define recess, as in the half-shell-shaped design. This cavity or this recess serves to receive an adhesive, which is applied to the formation of the adhesive bond on the lower part of the two profile elements 45, 46, that is, for example, on the profile element 45 of FIG. 5. This adhesive is sufficient over the entire width 26 of the profile piece 24, for example sausage-shaped, applied. During the subsequent mechanical compression of the impact lock excess adhesive is pressed out over the two open sides of the adhesive member 31.

As an adhesive, any commercially available adhesive can be used, but preferably with regard to the elastic properties of the profile piece 24, an adhesive with elastic properties is used.

In principle, it is also possible in the embodiment of the adhesive element that only the first profile element 45 or the second profile element 46 is disposed on the two end faces 28, 29 of the profile pieces 24, and that the respective further profile element 46 or 45 by a own component is formed, for example, has two juxtaposed half-shells, which are curved in the same direction.

The composite of the clamp member 30 and / or adhesive member 31 butt lock may have in the direction of the longitudinal center axis 40 has a length which corresponds to a maximum of 10%, in particular a maximum of 5%, the length 25 of a profile piece 24.

It is also possible that more than one clamp member 30 and / or more than one adhesive member 31 are arranged to form the impact lock on the end faces 28, 29 of the profile pieces 24, for example, two, three, four, etc., wherein the plurality of clip elements 30 and / or adhesive elements 31 can each be arranged next to one another or an alternating arrangement of the clip elements 30 and adhesive elements 31 is also possible. It is also possible for a number of adhesive elements 31 different in number to the number of clamping elements 30 to be provided.

In principle, as already stated, both the clamp element 30 and / or the adhesive element 31 can be designed at least partially as separate components or profile elements of the intermediate profile 5. Preferably, however, the clip elements 30 and / or the adhesive elements 31 or their respective components are each formed integrally with the respective profile pieces 24.

As can be seen in part from FIG. 6 and better from FIG. 7, the intermediate profile 5 preferably has an expansion element 47. This expansion element 47 serves to increase the expansion area or compression area of the already elastically executed intermediate profile 5.

The expansion element 47 may be an integral part of the intermediate profile 5. For example, the expansion element 47 may be made of a metal, in particular steel, and have already been connected to it during the production of the profile pieces 24 for the intermediate profile 5, for example by scorching. It is also conceivable that the expansion element 47 is connected by a different connection method with the profile piece 24, for example, with screws or by gluing. On the other hand, it is possible that the expansion element 47 is made of the material of the profile pieces 24, in particular is made in one piece with these.

The expansion element 47 preferably has a W-shaped cross-section viewed in the direction of the longitudinal central axis 40. But there are also other cross-sectional shapes used, for example, V-shaped or accordion-shaped.

Preferably, the expansion element 47 extends in the direction of the longitudinal central axis 40 over the entire length 25 of the profile pieces 24, or in the sequence also over the entire length of the intermediate profile. 5

Preferably, the expansion element 47 is centrally - viewed in plan view - arranged in the profile pieces 24, in particular symmetrically with respect to the longitudinal central axis 40 (viewed in the direction of the longitudinal central axis 40). But it is also possible that the expansion element 47 is arranged offset in the direction of one of the two longitudinal end faces 18, 19 of the profile piece 24 from the center out.

The expansion element 47 preferably has, as can be seen in particular from FIG. 3, a wavy course in the direction of the longitudinal central axis 40 in plan view of the profile piece 24. But there are also gradients in this direction possible, for example, straight-line.

It is further preferred if the expansion element 47 has a wall thickness 48 which is between 10% and 30%, in particular between 14% and 20%, of the height 21 of the profile piece 24.

If the profile pieces 24 have an expansion element 47, the impact lock can follow the course of the expansion element 47, as can be seen in particular from FIG. 6. In the lower portion of FIG. 6, the front end region of the further profile piece 24 adjoining the profile piece 24 is shown by dashed lines. The butt lock, i. In particular, the clamping element 30 and / or the adhesive element 31, starting from the left longitudinal end face 18 has a flat, i. in the installed position of the profile piece 24 usually horizontal, first region 49 which extends approximately at the level of the center plane 43 (Fig. 2), and to which a rising second region 50 connects. Subsequent to this second rising region 50, a planar third region 51, which is usually horizontal in the installed position, follows, but in contrast to the first, planar region, now extends approximately at the level of an upper surface 52 of the profile piece 24. The fourth region 53 adjoining the third region 51 is sloping and extends approximately from the upper surface 52 to approximately the bottom surface 20. Following the W-shaped profile, this fifth region 53 is adjoined by a fifth rising region 54, which extends also as the fourth region 53 extends over at least approximately the entire height 21 of the profile piece 24. It then follows again (not shown) a sloping area, then a rising area, then a flat area and then a sloping area to about the height of the center plane 43, and then at the height of the first area 49 a level, horizontal Area which extends into the second longitudinal end face 19. Thus, the contour of the expansion element 47, viewed in the direction of the longitudinal center axis 40, is modeled by the impact lock, the first slope, i. the second region 50 is located just in front of the expansion element 47 or, accordingly, the last sloping region in the described sequence just after the expansion element 47. In particular, a distance between 20 cm and 40 cm from the expansion element 47 at a width 26 of the Profile piece of about 270 cm meant.

If, instead of the considered in the direction of the longitudinal central axis 40 W-shaped cross-section of the expansion element 47 another be used, for example, the V-shaped, the course of the shock lock is adjusted accordingly.

However, there is also the possibility that the impact lock viewed in front view of the intermediate profile has at least one rising and at least one sloping region, even if no expansion element 47 is arranged. This has the advantage that the surface available for the formation of the butt-lock is increased, for example the adhesive surface.

It can be seen from Figures 3 and 6 that one or more apertures 55 may be formed in the profile piece 24, preferably in the vicinity of, e.g. closely spaced from the longitudinal end faces 18, 19 are situated. About these breakthroughs 55, it is possible to anchor the profile pieces 24 and subsequently the intermediate profile 5 in the support elements 7, 8, for example by means of a composite anchor. Preferably, these apertures 55 are formed as elongated holes with a longitudinal extent in the direction of the longitudinal central axis 40. A preferred cross-sectional shape of these apertures 55 is shown in FIG. 6.

In addition to or as an alternative to this anchoring method of the profile pieces 24, there is the possibility that these are glued over part of the bottom surface 20, namely that part of the support surface 44 on the support elements 7, 8, at least approximately over the entire surface with the latter.

From Fig. 3 is further broken lines can be seen that the angle profile strips 12, 13 in the direction of the longitudinal central axis 40 may also have a wave-shaped course of facing each other end faces, this course can follow the undulating course of the expansion element 47.

For the sake of order, it should finally be pointed out that in order to better understand the structure of the device 1 for bridging an expansion joint 2 in a roadway, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
