DEFORMATION PREVENTION DEVICE FOR COLUMN OF FILLING TYPE STEEL PIPE CONCRETE CONSTRUCTION AND CONSTRUCTION METHOD FOR COLUMN OF FILLING/COVERING TYPE STEEL PIPE CONCRETE CONSTRUCTION

摘要

PURPOSE: To prevent the column side surface of a steel pipe surely from being deformed in depositing concrete without reducing work efficiency and increasing the weight of the steel pipe. ;CONSTITUTION: A deformation prevention device is used when concrete is charged under pressure into a steel pipe 1 erected so that it passes through each story of a building so as to construct a column of filling type steel pipe concrete construction. In the device, a pair of bolts 10 are passed between the column side surfaces of the steel pipe opposed to each other in crossed form. Also a nut 11 is screwed onto the end part of the bolts 10 projected to the outside of the column side surfaces so as to arrest the column side surfaces of the steel pipe 1.;COPYRIGHT: (C)1996,JPO
