摘要

PROBLEM TO BE SOLVED: To cope even with a size change in a concrete column by one horizontal fastening metal fitting, by accurately and quickly assembling a column form, while easily constructing a cast-in-place reinforced concrete column.;SOLUTION: When constructing a reinforced concrete column by combining a form panel, the cast-in-place reinforced concrete column is constructed by using a column form unit composed of the form panel, a plurality of longitudinal sash bars installed in parallel in the longitudinal direction of respective outside surfaces of the form panel and a plurality of expandable horizontal fastening frames for forming the column form by fastening from the four sides by surrounding the outside of the form panel with the longitudinal sash bar assembled in a square shape.;COPYRIGHT: (C)2010,JPO&INPIT
