Src造柱脚の定着構造

Anchorage structure of src column base

Abstract

PURPOSE:To further enhance the efficiency of a reinforcing work by burying threaded reinforcements into a foundation beam and inserting an upper projected part of the threaded reinforcements into holes of a base plate of a steel post and fixing an intermediate part of the threaded reinforcements with the base plate. CONSTITUTION:Threaded reinforcements 2 which fix an enclosed type fill-up threaded fixture 1A with the lower end are placed together with reinforcing bars, thereby forming a lower stage foundation beam 7A. A steel post is erected to the threaded reinforcements 2 projecting upward while it is being aligned with holes of a base plate. Then, after a penetration type filled-up threaded fixture 1B is dropped from the upper end of the threaded reinforcements 2 and temporarily fixed with the threaded reinforcements 2, the post is firmly fixed with a grout material. hoop bars 4 and reinforcing bars of the upper stage foundation beam 7B are placed where concrete is cast, thereby forming the upper stage foundation beam 7B.
