Title:
INTERVAL HOLDING DEVICE FOR CONCRETE FORM
Document Type and Number:
Japanese Patent JP3896574
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an interval holding device for a concrete form capable of preventing concrete before hardening from leaking through a clearance between the form and base concrete and leftovers of the interval holding device from remaining in concrete and being usable repeatedly.
SOLUTION: A frame body 10A is formed into a gantry shape and a lower end of the form a is erected while it is abutted on the base concrete (h). Since there is no clearance between the base concrete (h) and a lower end face of the form a, it is possible to prevent concrete (g) poured between the forms a from leaking to the outside of the form a. Secondly, since the leftovers of the interval holding device 10 does not remain in the concrete (g) after placing it, deterioration of the concrete (g) due to corrosion of the leftovers does not occur, and construction cost can be reduced because the interval holding device 10 can be repeatedly used.
