Abstract
The invention relates to a sealing device for sealing joints between abutting concrete structures having an injection-channel body which is to be fitted on a concrete surface and has an injection channel for introducing sealing material, whereby the injection channel has on the joint side at least one outlet opening for the sealing material and a covering strip which prevents the penetration of material through the outlet opening into the injection channel from the joint side, whereby the covering strip is a stop-valve strip in the form of a hollow-profile strip.
Claims44
Sealing device for sealing joints between structural bodies, and particular between abutting concrete structres, having
- an injection-channel body (2) which is to be fitted on a surface (26) of one of the structural bodies and has an injection channel (12) for the introduction of sealing material;
- the injection channel (12) having, on the joint side, at least one outlet opening (11) for the sealing material, and,
- a covering strip which prevents material from penetrating through the outlet opening (11), into the injection channel (12), from the joint side, characterized in that the covering strip is a stop-valve strip (3) in the form of a hollow-profile strip.
Hollow-profile strip for a sealing device for equipping an injection channel of an injection-channel body, the injection channel being arranged in a joint region between structural bodies, in particular between two sections which are to be concreted together, for the purpose of blocking the channel against the penetration of slurry during the concreting, characterized in that the hollow-profile strip (3) is designed, in particular structured, such that the hollow-profile strip (3) preferably yields in a predetermined manner and reduces its cross-sectional area, when injection material from the injection channel (12) subjects the hollow-profile strip (3) to pressure, such that the injection material moves out of the sealing device (1), under the pressure, in the lateral direction past the hollow-profile strip (3) with the reduced or tapered cross section.
