<P>PROBLEM TO BE SOLVED: To provide a space holding tool of concrete formworks which can prevent mortar from peeling or dropping, when the mortar is filled in a hole formed on a placed concrete wall after removal of a separator cone. <P>SOLUTION: A space holding tool of formworks has cones 2 and 2 to receive opposing inner faces of the formworks and hold the formworks at intervals between the formworks at both end parts of a separator 1. The cone 2 is covered with a cup-shaped covering member 3. After placing and curing of concrete, the formwork is removed and an end part of the separator projecting from the cone 2 is removed by bending at a breaking-off groove 5. When the end part is removed along with the cone 2 and the covering member 3 from a concrete wall surface, a remaining end part of the separator after the removal projects from a central part of the bottom of the hole 18 formed by the removal of the covering member 3, so that mortar 19 to be filled in the hole 18 is prevented from peeling and dropping by coupling force between the mortar and the projecting end part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
