JOINT STRUCTURE WITH CONDUCTOR FOR LIGHTENING ARRESTING

摘要

PROBLEM TO BE SOLVED: To dispose a conductor for lightening arresting at a joint after concrete is placed. SOLUTION: A joint 14 comprises a joint body 14a; and a cap 14b, and a support cap 14c containing a conductor 15 for lightening arresting is insertable in the cap 14b. During placing of the concrete 3, a simple closing cap is fitted in instead of the support cap 14c. After the concrete 3 is placed, the cap is removed and the support cap 14c with the conductor 15 for lightening arresting is fitted in. This constitution separates a work to place the concrete 3 and a work to dispose the conductor 15 for lightening arresting from each other, improves workability, and facilitates inspection and repair of the conductor 15 for lightening arresting.
