<p>PROBLEM TO BE SOLVED: To remove a covering material of a corresponding part, by partially curing by a cover, when a covering material 1 is stuck to the lower side whole area of a slab S or the whole area of a beam 2.SOLUTION: A removal method includes: a process of arranging a cover 3 so as to cover a part of a beam 2 by opening a work space, by fixing an upper edge 3a of the cover 3 to a slab under surface on both sides of the beam 2 stuck with a covering material 1; a process of forming covering material solidification ranges 1a at mutually separated two places by spraying a solidification agent on the covering material 1 stuck to the beam 2 by using a work port 3b while sucking the inside of the arranged cover 3; a process of allowing the covering material solidification range 1a and the cover 3 to abut on each other by pressing the cover 3 to the beam 2 in the covering material solidification range 1a after forming the covering material solidification range; and a process of removing the unsolidified covering material 1 between the covering material solidification ranges 1a by using the work port 3b while sucking the inside of the cover 3 between the covering material solidification ranges 1a after abutting on the cover.</p> |
