Document Type and Number:
WIPO Patent Application WO/2011/132839
Kind Code:
A1
Abstract:
The present invention relates to a packer for injecting a repairing liquid for repairing a crack in a concrete structure. A packer of the present invention is connected to an injector for injecting a repairing liquid into an injection port formed near a crack in a concrete structure, and is installed at the injection port. The packer comprises: an injection member in which a hole (1) is internally formed in the axial direction, and a nipple (2) for connecting the injector, a multi-angle part (3) for tightening, a round pipe (12) formed to have a small diameter with a stepped height with respect to the multi-angle part (3), and a male screw (11) are sequentially formed from the outer side end thereof; a collet-type sleeve (4) slidably coupled in a manner surrounding the round pipe (12) so as to be caught at one side thereof, and having a plurality of grooves formed at the outer side thereof; rubber sleeves (5) coupled so as to surround the round pipe (12), and sequentially adhered to the collet-type sleeve (4); a latch-type nut (6) which is screwed to the male screw (11) of the injection member, and in which a sawtooth-shaped latch wing (14) is formed along the outer perimeter thereof so as to have an external diameter greater than an internal diameter of the injection port and thus reverse rotation is controlled when coupled to the injection port.
