Abstract

PURPOSE:To form a holding part of a segment held by a segment catching device, by making use of a mold wherein a box-shaped casing for a hollow space forming is provided with a rotor as a specific core. CONSTITUTION:After a rotor 2, whose groove surface fits over a holding reinforcing rod 1a, has been mounted with the groove surface down within a casing 1, the rotor 2 is turned in the direction of X. Then a fixing bar 3 is fixed to the rotor 2 and a fixing plate 4 on the top side of the casing respectively with a bolt and nut 5. After the casing 1 and rotor 2 have been provided by placing concrete outside of them under this state, the fixing plate 4 is removed, the fixing bar 3 is turned in the direction of an arrow Y-Y' and adhesion of cement and friction are eliminated. When the casing 1 and rotor 2 are pulled off by removing the fixing bar 3 and turning rotor 2, a hole having the holding reinforcing rod 1a penetrating through in the middle of a hollow space is formed.
