Description

  The present invention relates to a still water curing structure and a still water curing method for water stopping an opening formed in a building construction body or the like.

2. Description of the Related Art Conventionally, in building construction, a housing opening such as an elevator installation location is continuously provided from the top floor to the bottom floor during the construction of the housing. Therefore, when it rains, water enters the enclosure through the opening. In general, when rainwater enters the construction surface where finishing work is performed, finishing work cannot be performed, which hinders the work process and causes a long construction period.
For this reason, in order to prevent rainwater from entering through the opening, a floor (hereinafter referred to as “waterproof floor”) on which water is cured is provided on the intermediate floor. As a still water curing method, a method of assembling a pillar material around an opening and covering the opening with a sheet material so as to cover a roof on the upper end of the pillar material is generally performed. Thereby, rainwater entering from the upper floor from the water stop floor can be stopped, and finishing work can be performed on the lower floor from the water stop floor. And, as the building construction progresses, the still water floor where this water curing is applied will be replaced with the upper floor.
In addition to such conventional water-stopping curing, a technique for water-stopping the opening is proposed in Patent Document 1, for example.
In Patent Document 1, a plurality of tube bodies that expand due to the inflow of liquid and extend in the longitudinal direction are arranged so as to close the openings at the entrance of an underground passage or the like. Connecting fittings (supporting means) for mounting are fixed to both ends of the tube body, and the mounting bracket supported by the supporting means is fixed to the opening side, and the connecting bracket for the tube body is fixed to this mounting bracket. To do. And the weir which inclines a tube body and obstruct | occludes an opening part by making a liquid flow in into a tube is installed.
