A-TYPE AND B-TYPE SQUARE TIMBER-SECURING METALS, AND METHOD OF RELOCATION OF SEPARATOR-EXTRACTION-TYPE LARGE FORM

摘要

PROBLEM TO BE SOLVED: To extract a separator 18 after curing of concrete in the state of leaving a cone cup 21 and a sheath pipe 22, and to relocate a scaffold-side large form, comprising a plurality of continuously arranged forms, to an upper floor.;SOLUTION: The form 1a to which an A-type batten securing metal 5a is fixed is arranged continuously to another form 1a on the side of the scaffold 42. A lateral batten 4 supporting a back side of the form 1b on the opposite side of the large form 31 to which the lateral batten 4 supporting the back side of the form 1a is fastened, and a batten fastening metal 24a are removed. By rotating and extracting the separator 18, the large form 31 is separated from a concrete skeleton. The large form 31 as a whole is relocated to the upper floor etc. Thus, according to the method of relocation of a large form, attaching and detaching work of the heavy and long lateral batten 4 can be omitted from the work on the scaffold, by relocation using a lifting machine like a crane in the state that the lateral batten 4 is secured.;COPYRIGHT: (C)2011,JPO&INPIT
