FIELD: construction.
SUBSTANCE: present invention pertains to a sealing device for sealing joints between adjacent concrete structures. The sealing device for sealing joints between structural blocks, and particularly between adjacent concrete structures, has a case with an injector channel, fixed on the surface of the structural blocks and with an injector channel for input of sealing material. The injector channel comprises, on the side of the joint, at least one outlet opening for the sealing material, and a covering bar, preventing penetration of material on the side of the joint through the outlet opening in the injector channel. The covering bar is a shut-off valve, made in form of a hollow cross-sectional bar. Description is also given of versions of the sealing device and a hollow cross-sectional bar for the sealing device.
EFFECT: design of a sealing device, meeting strength requirements and guaranteeing reliable joining, as well as easier manual and production assembling, as well as prevention of material passing through the through-running channel from going out.
