Abstract
A wire method of a reinforced concrete structure, and a guide pulley apparatus for the method, wherein a cutting wire 18 guided by a pair of guide pulleys 7a, 7b disposed on the same plane as a scheduled cutting surface of a reinforced concrete structure 2 is caused to endlessly circulate and travel along the surface of the reinforced concrete structure under a regulated tension and at a regulated travelling speed through an auxiliary guide pulley 8c for separating one portion of the cutting wire from the other portion thereof.
Claims20
A wire sawing method of a reinforced concrete structure, comprising the steps of:
- disposing a pair of main guide pulleys on the same plane as a scheduled cutting surface of a reinforced concrete structure;
- guiding a cutting wire through said pair of main guide pulleys such that said cutting wire winds around said reinforced concrete structure along said scheduled cutting surface and makes a circulating path via a wire driving pulley of a wire driving device;
- disposing an auxiliary guide pulley on a loosening side of said circulating path between said main guide pulleys and said wire driving pulley so as to widen said circulating path;
- and
- driving said cutting wire by said wire driving pulley under a regulated tension and at a regulated traveling speed.
In a wire sawing apparatus wherein a pair of main guide pulleys are disposed on the same plane as a scheduled cutting surface of a reinforced concrete structure along the surface of said reinforced concrete structure and a cutting wire is wound on said reinforced concrete structure from outside at least one of said main guide pulleys to make a circulating path, said cutting wire being driven by a wire driving pulley of a wire driving device under a regulated tension and at a regulated traveling speed, a guide pulley apparatus for wire sawing characterized in that an auxiliary guide pulley is disposed on a loosening side of said circulating path between said main guide pulleys and said wire driving pulley so as to widen said circulating path of said cutting wire guided by the pair of said main guide pulleys.
