Title:

TENSILE MATERIAL ARRANGEMENT METHOD AND ITS DEVICE

Document Type and Number:

Japanese Patent JP3676560

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To efficiently and shortly arrange PC tensile materials in place when the side wall of a cylindrical structure in a prestressed concrete structure is constructed in a sliding form technique.
SOLUTION: An endless loop indexing rope 41 is arranged above a concrete placement position in an almost horizontal loop shape. Plural PC tensile materials 100 (100a,...) are temporarily locked at their ends to the indexing rope 41, the indexing rope 41 is moved with a driver 31 and a drive chain 33, the PC tensile materials 100 are pulled out along the indexing rope 41 and the pulled-out PC tensile materials are dropped to a concrete placement position on a cylindrical structure and arranged at desired positions.
