METHOD FOR ANCHORING EMBEDDED FORMWORK IN CONCRETE STRUCTURE CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method for anchoring an embedded formwork in a concrete structure construction using an embedded formwork by a precast slab with a connector in which the peeling of an interface between the precast slab and concrete or mortar of the back side placed closely to this is hard to be caused, and the degradation of placement performance of the concrete or mortar placed to the back side due to contact between a connector and an arranged rebar at the back side of the precast slab is configured to be improved, and to provide the precast slab for the embedded formwork that can be properly used for the anchoring method.SOLUTION: A method for anchoring an embedded formwork in a concrete structure construction is characterized by: installing an embedded formwork 6 with a connector comprising a nonmetallic fiber mesh-shaped body provided in the back side at predetermined intervals, against a chipping surface 7 of a wall height column 5, which is one of concrete structures with a rebar 4 arranged therein; anchoring the embedded formwork 6 by placing cement-based shrinkage-compensating mortar 8 between the chipping surface 7 and the embedded formwork 6; and integrating the building frame of the wall height column 5 with the embedded formwork 6 and repairing an existing wall height column 5.
