MORTAR PEELING DEVICE

摘要

[Problem];A mortar peeling method which can keep a sound generated during a peeling work to an allowable quiet sound and can peel a mortar off a concrete framework smoothly.;[Solution];In a mortar peeling method, by gradually extending a piston rod 42 of a hydraulic jack 13 in a mortar peeling device 10A forward in one direction, a cutter 14 is gradually advanced forward in one direction so as to execute a mortar peeling process of peeling a mortar 21 with a predetermined thickness off a concrete framework 20 by using the cutter 14. In the mortar peeling method, after the piston rod 42 of the hydraulic jack 13 is extended forward in one direction and the mortar 21 is peeled, by retreating the piston rod 42 rearward in one direction, a session of the mortar peeling process is completed.
