for pahyeonggwan connection, which represents an improved tightness watertight sheet

摘要

The present invention is a projection on the outer peripheral surface connecting the positive pahyeonggwan is formed in a spiral, an improved watertightness indicating that the number of face-to-face about the watertight sheet pahyeonggwan connection, the connection part of the amount to be connected pahyeonggwan swellable resin; Including the inner surface of the water swelling resin layer and heat-adhesive resin layer can be adhered to during construction amount pahyeonggwan; And is composed of the heat-adhesive resin layer of a three-layer structure consisting of an outermost layer comprising the inner surface of the flexible cushion. ; pahyeonggwan watertight sheet for connection according to the invention the sealing is possible and because of the heat adhesive resin layer during construction, and can to leak or the like, which may be caused by external shock error, long-term use on the construction or water-swellable swelling characteristics of the resin layer by the number may represent the effect of preventing the leakage of the second seal by being completely. In addition, for a water-tight sheet pahyeonggwan connection according to the invention is relatively simple structure, its construction is simple and has the advantage that the operation time shorter.
