SEALING PROFILE FOR EMBEDDING INTO A MOULDING OF CURABLE MATERIAL

Abstract

A sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1). The profile region (2) has, at least in a subregion (6), fibres (5) which are fixedly connected to the sealing profile (1) and extend beyond the profile region surface (4).

[0030] FIG. 1 schematically shows a sealing arrangement 100 comprising a sealing profile 1, as also shown in FIG. 1C, and a moulding 3, in this case a concrete tubbing element for tunnel construction, of which only a detail is shown.

[0031] The sealing profile 1, which has a generally hexagonal cross-section in this case and consists of an elastomer material, has a profile region 2 (shown crosshatched here) having a profile region surface 4 facing the moulding 3. The profile region 2 comprises a profile base 8 having a profile base surface 41 and base-side profile flank parts 11 of the lateral profile flanks 10 having a profile flank surface 42. The sealing profile 1 has a profile back 9 opposite the profile base 8 and rear flank parts 12. Fibres 5 are embedded at one end directly in the sealing profile 1, i.e. in a portion 6 of the profile region 2, in this case the profile base 8. In the embodiment provided here with two dovetail-like, mutually spaced anchoring feet 16, the portion 6 with the fibres 5 lies in the region of the profile base 8, between the anchoring feet 16. The sealing profile 1 has longitudinal channels 15 which run in the longitudinal direction of the sealing profile 1, as is also known in profiles from the prior art.

[0032] In the sealing profile 1 shown here, there are flank-side sealing lips 14, which are each arranged at the level of the plane 13 (see FIG. 2) above which the rear flank parts 12 and below which the base-side flank parts 11 lie in the diagram. The sealing profile 1 is in this case surrounded by the curable material, for example concrete, on the base side as far as the sealing lips 14. In the embodiment shown here, the sealing profile 1 is anchored both via the anchoring feet 16 and via the fibres 5. By means of their connection at points to the moulding 3, the fibres 5 prevent or impede displacement of the sealing profile 1 in the longitudinal direction thereof, i.e. in the direction perpendicular to the plane of the paper.

[0033] FIG. 2 schematically shows different embodiments of a sealing profile 1 according to the invention in cross-section. FIG. 2A shows an embodiment of a sealing profile 1 according to the invention without anchoring feet 16, with fibres 5 vulcanised directly into the profile base 8. FIG. 2B shows an embodiment of a sealing profile 1 according to the invention without anchoring feet 16, with fibres 5 connected to the profile base 8 via an adhesive layer 7. FIG. 2C shows the embodiment of a sealing profile 1 according to the invention shown embedded into a moulding 3 in FIG. 1, with two anchoring feet 16 and fibres 5 embedded during vulcanisation. FIG. 2D shows an embodiment of a sealing profile 1 according to the invention with anchoring feet 16 and with fibres 5 connected to the profile base 8 via an adhesive layer 7. In each case, cross-sections through a strand-like sealing profile 1 are shown, i.e. sections transverse to the longitudinal axis of the strand-like sealing profile 1, which must be imagined as extending above and below the plane of the paper.

[0034] The embodiments shown in FIGS. 2A and 2B do not have any anchoring feet 16. The embodiments shown in FIGS. 2C and 2D have two, in this case dovetail-like, mutually spaced anchoring feet 16 which extend from the profile base 8. Fibres 5 are embedded at one end either directly into the profile base 8 (FIGS. 2A, C) or into an adhesive layer 7 (FIG. 2B, D) on the profile base surface 41. In embodiments with anchoring feet 16 (FIGS. 2C, D), the fibres 5 are arranged in the region of the profile base 8 between the anchoring feet 16. The sealing profiles 1 have longitudinal channels 15 which run in the longitudinal direction of the sealing profile 1, as is also known in profiles from the prior art.

[0035] FIG. 3 shows a cross-section through an embodiment of a sealing profile 1 according to the invention which is particularly suitable for concrete pipes or shafts. The sealing profile 1 in this case has anchoring feet 16 and fibres 5, with the aid of which the sealing profile 1 can be embedded into a concrete pipe sleeve (not shown). The fibres 5 are either connected to the profile region 2 which faces the subsequent moulding 3, i.e. the concrete pipe sleeve, by means of an adhesive layer 7 on the profile region surface 4 (see FIG. 3A) or directly embedded into the profile region 2 (see FIG. 3B). The fibres 5 are arranged in portions 6 of the profile region 2 between the anchoring feet 16. In this case too, longitudinal channels 15 are present in the sealing profile 1.

[0036] FIG. 4 shows a cross-section through a further embodiment of a sealing profile 1 according to the invention which is particularly suitable for concrete pipes or shafts. In this case, the fibres 5 provided over an extended portion 6 are used substantially to anchor the sealing profile 1. The only anchoring foot 16 still present in the edge region of the sealing profile 1 is used substantially to prevent the ingress of liquid concrete during casting of the moulding 3. In this embodiment too, the fibres 5 are either connected to the profile region 2 which faces the subsequent moulding 3, i.e. the concrete pipe sleeve, by means of an adhesive layer 7 on the profile region surface 4 (see FIG. 4A) or directly embedded into the profile region 2 (see FIG. 4B).
