[Scaffolding Construction Achievements] Seto Ohashi Anchorage (4A)
Install concrete anchors on the underside of the overhang and set the rail horizontally as the suspension point!
We would like to introduce our construction achievements for the concrete painting work on the overhang section of the anchorage (4A) of the Nanbi-San Seto Ohashi Bridge. Since work on the underside of the overhang section cannot be performed using a gondola, we utilized a "rack scaffold." Concrete anchors were installed on the underside of the overhang section, and rails were set up horizontally from these anchors. Due to the steep angle of the overhang, which is 60 degrees, the scaffold is designed in a stair-like manner. 【Overview】 ■ Location/Prefecture: Sakaide City, Kagawa Prefecture - Kurashiki City, Okayama Prefecture ■ Client: Honshu-Shikoku Bridge Expressway Company Limited ■ Construction Company: Bridge Engineering Co., Ltd. ■ Start Date of Use: October 2008 (initial) ■ Local workers' experience with rack scaffold installation: First time ■ Presence of rack scaffold handling instructor: Yes *For more details, please refer to the PDF document or feel free to contact us.
