Abstract

PURPOSE:To save drastically labor required for cleaning operation of a concrete shuttering constituting a mold, by a method wherein a plurality of the throughlike concrete shutterings put on a table along openings each are cleaned in order by a cleaning device of an inner circumferential surface and a cleaning device of a circular- arc-shaped end part. CONSTITUTION:A concrete thin piece stuck to inner circumferential surfaces of throughlike concrete shutterings 11, 12 fitted to a fitting seat is removed with a rotary brush 33. A concrete thin piece stuck to a circular-arc-shaped part of the same concrete shutterings 11, 12 is removed with a rotary brush 34 and a turn table 32 is turned intermittently equiangular distance by equiangular distance, through which a plurality of the throughlike concrete shutterings 11, 12 put on a table 32 can be cleaned in order. With this construction, labor necessary for cleaning operation of a mold can be saved drastically and efficiency also in the cleaning operation is improved. Then since a mold release agent is sprayed on an inner circumferential surface of the concrete shutterings 11, 12 through nozzles 36A, 36B, a coating process of a mold release agent by manual operation can be omitted. Furthermore, in case of the throughlike concrete shutterings 11, 12, a cleaning process also of the end part, an outer circumferential surface and the top fo a disclike concrete shuttering is automated and the labor can be saved.
