Description

  The present invention relates to a temporary scaffold opening curing tool for curing an opening of a temporary scaffold with a panel material.

  Temporary scaffolding will be built around and in the building renovation work. An operator works on the temporary scaffold, but an accident has occurred in which a tool, material, or the like is accidentally dropped. For this reason, the temporary scaffolding requires curing to protect passersby from falling objects.

  Conventionally, as for the curing of the temporary scaffold, Japanese Utility Model Publication No. 4-2408 discloses a pair of guide members that are fixed to the frame of the temporary scaffold and arranged so that the openings of the grooves face each other, and slide into the openings of these guide members. There has been proposed a slide-type falling object protection curing plate having a steel cloth plate that can be fitted (Patent Document 1). According to Patent Document 1, it is said that the gap between the temporary scaffolding and the building can be completely closed by sliding the cloth board to the building side.
