Title:
SEPARATOR WITH DRAWING-OUT AUXILIARY MEMBER, CONE WITH NOTCHED STEP, AND SEPARATOR SEAT WITH NOTCHED STEP
Document Type and Number:
Japanese Patent JP3867870
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perfectly prevent defects such as water leakage from around a separator, stains on a wall, creaking sound, dewing on the inner wall face, by removing the separator after execution of the wall and recover and reuse it after concrete has cured.
SOLUTION: A film-form material 2 excellent in the tensile strength and water-resistance and easily peeled out of concrete is stuck on a sheet-form material 1 which is strong against pressing forces in the right angled direction against the surface but weak against pressing forces in the in-plane direction and which is easily deformed. A notched step having the same diameter with a drawing-out auxiliary member 3 of a separator is formed at the separator body 4 coated with the drawing-out auxiliary member to make a tubular form and the cone 8 or the opening part of the screw hole 5 of the screw seat.
