PROBLEM TO BE SOLVED: To provide a semi-cylindrical body for constituting a tool for column steel bar assembly that can be mounted on a column steel bar having a hook at a tip part, and stabilizes a state of attachment to a template by locking.SOLUTION: There is provided a semi-cylindrical body H for constituting a tool 10 for column steel bar assembly having a cylindrical body 1 which can be inserted into a template 5 having a through hole 1b into which a steel bar 4 can be inserted and also having a hole part 6 determining the installation position of the steel bar 4. The semi-cylindrical body H is for constituting the tool 10 for column steel bar assembly that comprises: an expansion part 2 made by swelling an axially intermediate part of the cylindrical body 1 constituted by combining end faces of two semi-cylindrical bodies H which extend along axes with each other; a lock projection part 3 which is formed projecting from the cylindrical body 1 at a position below an under surface of the expansion part 2, and positioning means S1, S2 formed on axially extending end surfaces of the semi-cylindrical bodies H. |
