WATER CUTOFF DEVICE OF HORIZONTAL SLIT AND WATER CUTOFF DEVICE OF VERTICAL SLIT

摘要

PROBLEM TO BE SOLVED: To provide a water cutoff device capable of completely cutting off water in flooding time, excellent in settlement even if a secular change and residual displacement are caused, and without having influence on building behavior in earthquake time.;SOLUTION: A water cutoff device 1 is provided for preventing flooding from a horizontal slit 25 opened in the horizontal direction, and is mainly constituted of a water cutoff plate 2 movably provided in the vertical direction in a lower side skeleton 26 of the horizontal slit 25 and blocking up an opening of the horizontal slit 25 when moved upward, a floating body 3 installed on the water cutoff plate 2 and raising the water cutoff plate 2 by buoyancy in flooding time and movable side packing 4 installed on the water cutoff plate 2 for abutting on fixed side packing 5 provided in an upper side skeleton 27 of the horizontal slit 25 when the water cutoff plate 2 blocks up the opening of the horizontal slit 25 and capable of fastening to the fixed side packing 5 by magnetic force.;COPYRIGHT: (C)2016,JPO&INPIT
