Flexible unit for repairing cracked part of concrete structure and maintenance method of cracked part using the flexible unit

摘要

The present invention relates to a flexible unit for repairing a crack part of a concrete structure, and to a method for repairing a crack part by using a flexible unit. When a leakage caused by a crack occurring on a rooftop floor or a wall surface of a concrete building is repaired, repairing can be conveniently and rapidly performed even without digging surrounding concrete of a cracked part. Thus, human and material resources can be remarkably saved, and at the same time a gap of a cracked part can be filled after a construction. The flexible unit is made of soft rubber or urethane material, and an insertion unit (30) inserted into a gap (20) of a crack is formed. The insertion unit (30) has laterally symmetrical vertical pieces (31) disposed at regular intervals to be integrally formed with an adhesive unit (40) having a laterally symmetrical structure.
