PURPOSE: To finish the water-insulating construction work of an underground external wall during the assembling work of the molding frame which is carried out on placing concrete for the building body, by applying a drive-in type for pacing concrete of external walls and providing a draining function to the molding frames.
CONSTITUTION: A drive-in type molding frame 4 is composed of a water-conductive layer 3 made of something like vinyl chloride and an attached water-permeable buffer layer 2 made of something like non-wooven cloth stuck therto. A plurality of water- conductive holes 3d vertically extending by a plurality of nearly T-shaped support pieces 3a, partition walls 3b horizontally connecting respective support pieces 3a and inner walls 3c parallelly arranged with the partition walls 3b are formed in this water- conductive layer 3. Accordingly, the excessive water of incompletely cured concrete in the concrete body 1 is drained by the attached buffer layer 2 and hence, the concrete becomes dense to increase the water-insulating ability. The water-conductive layer 3 prevents concrete cracks after curing and leakage water to the room side, from inner defects of something like separator to the lower part of the molding frames 4.
