A known sealing insert (FR-PS 2 116 665) consists of ίηίτ KaUtSChukplatfeej which “has narrow incisions on the top and bottom in the longitudinal direction of the joints, which are offset from one another in such a way that even folding is possible. The load-bearing capacity of the known sealing insert is unfavorable despite the relatively thick-walled profile design. Although the known sealing insert is limited in its application to small gap widths, it requires a great deal of space in terms of width.

The innovation is based on the task of finding an easily foldable, material-saving design for a sealing insert that is nevertheless load-bearing and that can be attached to the edge strips with little effort.

According to the innovation, this object is achieved in that the folding ribs on a, the joint gap bridging, with respect to the folding ribs oppositely curved band, with this in one piece, are placed, and that the connecting parts can be buttoned into the edge strips.

This cross-sectional structure according to the invention has the effect that When closing the joint, the upward movement of the folding ribs is compensated by the downward movement of the supporting lower band, so that the desired joint seal is always flat with the surface to be sealed is guaranteed. The profiling according to the innovation on the one hand enables the sealing insert to be folded in

with little resistance; on the other hand, the tension in the lower load-bearing band causes the sealing insert to stiffen against vertical loads which, like a hanging structure, are carried into the lateral fastenings.

A particularly advantageous embodiment of the sealing insert consists in the fact that folding ribs and tape one or more contiguous, transverse to the joint gap next to each other Form squares standing on top. Such squares favor the folding of the profile parts against the vertical square diagonal. In general, form one or more pleat ribs, along with the lower band an irregular square -

The sealing liner is \ · \ cross section preferably .symmetrisch formed such that the vertical diagonal coincides with the center box with the vertical center plane of the sealing insert. In the one embodiment, the sealing insert comprises an odd number of folding ribs, preferably one, three or five folding ribs, which are combined on their underside by the said band.

The forces are transferred to the joint edges in that the joint edge-side folding ribs and the tape are combined into one common side web open out, on which a lateral connection part is attached to the outside.

Particularly smooth driving can then be achieved

if, in the case of the sealing insert according to the innovation, the side bar runs flush with the top of the joint. These Measure sets an opening of the claws in the edge strips to the surface adjacent to the joint gap ahead · When driving on the joint, especially by vehicles with small wheels, these then go from the rigid edge profile to the buttoned-in connector and then on the even softer middle section of the profile, which is not supported from below.

In the embodiment with the flush course of the side web with the top of the joint, it continues it is easier to button the sealing insert in and out of the edge strips, as this is done from above the joint can happen - This embodiment even makes it possible to

for low vertical loads, with (small gap widths that only require a single folding rib, to omit the band below it. The fact that in this case the folding rib is directly at the level of the carriageway level is supported, their sinking into the joint gap is avoided under load, even without in this case the folding rib is completed downwards to form a closed square.

The sealing insert according to the innovation is particularly suitable for traffic areas with light traffic, that is for example parking areas, airport driveways, shopping centers, etc. They are due to the road-level closure

also safe to walk on. The sealing insert according to the innovation is also suitable for installation in walls or Ceilings of buildings, with a 9O ° deflection a horizontal plane in a vertical plane can be realized without difficulty.

Further details and features of the innovation are the following description, the claims and the Refer to drawing.

Figures 1 to 5 of the drawing each show, in a vertical section, different variants of sealing inserts built into expansion joints.

The sealing insert 1 shown in FIG. 1 made of rubber or another elastomer has in the area of the joint gap 2 only a single upward-facing folding rib 3. The apex of the folding rib is always approximately at the level of the surface 4 of the edge strips 5. The side connection parts 6 of the sealing insert are in corresponding, buttoned undercuts 7 open towards the joint gap, the undercuts being formed by claws ß, 9 of the edge strips are limited. The edge strips themselves are anchored in the joint (not shown) by means of screws 10. The grooves or openings 11 in the top of the edge strips for inserting the screws 10 are means separate rubber seals 12, which engage laterally in grooves in the edge strips, sealed. On the bottom of the folded rib 3, the sealing insert 1 has the band 14. To the side, the folds and ribbon form each

together a side web 15, which merges into a connecting part 6 towards the outside.

In the following embodiments according to FIGS. 2 to 3, the anchoring of the edge strips is omitted. The edge strips 16 from FIG. 2 have the undercuts 7 already described in relation to the figure, which are open towards the side wall of the joint gap 2. The lateral connecting parts 6 of the sealing insert are held in the undercuts 7 by simply buttoning them in, that is to say without additional fastening means. A total of three folding ribs 18, 19, 20 are placed on the upper side of the band 17. The middle folding rib IS is symmetrical with respect to the vertical plane through the center of the joint gap. The two lateral folding ribs 18, 20 adjoin, on the one hand, ¹ on the side webs 15 and, on the other hand, at mid-height on the central folding rib 19. Towards the bottom, the rectangle delimited by the folding ribs is completed by the band 17 in each case. As in all other exemplary embodiments, in the case of the sealing insert Ib according to FIG. 2, each lateral connection part 6 is designed as a tubular hollow profile with an approximately triangular cavity; this makes it easier for the connecting parts to be pressed together when they are buttoned.

The sealing insert Ic according to FIG. 3 has a total of five Folding ribs 22 to 26, each of the lateral folding ribs 22, 23, 25, 26 forms together with the adjacent folding rib and the band 27 an unequal square; the middle folding rib 24 forms together with the band 27

such a square. When the edge strips are brought together, the squares fold against their roughly vertical diagonal together. While the folding ribs have the tendency to bulge the sealing insert upwards, this causes the Belt 27 connecting fold ribs at the bottom just has the opposite effect, so that a fold is planar when viewed on the surface he follows. In the case of the sealing insert according to FIG. 3, the side webs 29 lie on the claws 30 inside the joint Edge strips on. The undercuts 31 in the edge strips for receiving the lateral connecting axles 6 of the Sealing insert are in Fig. 3 and also in the following FIGS. 4 and 5 compared to the embodiments of FIGS. 1 and rotated about 90 °. The connection parts can be buttoned in here from above. This doesn't just do that Buttoning easier; at the same time, it enables buttoning for particularly narrow expansion joints. The width of the edge strips remaining on the surface 32 is greatly reduced, which is architecturally desirable is.

FIG. 4 shows an embodiment similar to FIG. 3, also with an upwardly open button-in groove in the edge strips 28, but only with three folding ribs 33, 34 and 35. This sealing insert Id is suitable for narrower expansion joints.

The is used to bridge even narrower expansion joints Embodiment of a sealing insert 1 e shown in FIG. 5. Similar to the embodiment according to FIG. 1, this has only one single folding rib 36, which laterally in webs 37 running at the top merges. In her upper

In the area 38, the webs rest on the claws 30 of the edge strips 28. The side notch 39 etv / a above the center of the connecting parts 6 is used to increase the grip and facilitate the deformation of the Dichtse.inlage when buttoning the connecting parts behind the claws of the edge strips. The band 41 below the dashed line drawn horizontal line 40 can because of the strong training and the surface flush arrangement of the lateral webs 37, 38 on which the folding rib 36 is suspended, as it were, are omitted without the properties of the sealing insert being significantly impaired.
