Abstract

PURPOSE: To carry out the work easily by placing concrete after attaching a plurality of core bodies to a supporting rod fixed to a through-hole forming position by thrusting sharp portions made at both ends into the formwork member. CONSTITUTION: A supporting rod 2 is crossed to a through-hole forming place inside a formwork 18 where steel bars 14 are assembled to a predetermined shape in response to a predetermined shape of a concrete structure. Then, expanding portions 4, 7 provided at the end portions of the supporting rod 2 are extended, sharp portions 8, 10 provided at both the ends are thrusted to the form work member 17 and the supporting rod 2 is fixed. Next, a plurality of core body 3 is installed to the supporting rod 2 at the position of installing hole 12 by pushing and widening an installing cleft 13. In this way, the supporting rod 2 is firmly fixed to the formwork member 17, and a through-hole can be formed by avoiding the filling of concrete by means of core body 3.
