[Scaffolding Construction Achievements] Tokyo Gaikan Expressway Takashu Viaduct

By having the "rack scaffolding" cover below in advance, we were able to eliminate the need for traffic regulations on the national road!

We would like to introduce our construction achievements for the new installation of the Takashu Viaduct (a steel 5-span continuous 2-main mixed girder bridge, and a steel 5-span continuous 2-main plate girder bridge) on the Tokyo Gaikan Expressway. To reduce the necessary traffic regulations on the national road during the installation of the full suspended scaffold, we adopted the "rack scaffold." By covering the area below the full suspended scaffold installation in advance, we were able to eliminate the need for traffic regulations on the national road. 【Overview】 ■ Location/Prefecture: Saitama Prefecture ■ Client: NEXCO East Japan ■ Construction Company: Tokyo Steel Bridge Co., Ltd. and Katayama Structec Co., Ltd. Joint Venture ■ Start of Use: January 2015 ■ Local Workers' Experience with Rack Scaffold Installation: First time ■ Dispatch of Rack Scaffold Handling Instructors: Yes *For more details, please refer to the PDF document or feel free to contact us.

[Scaffolding Construction Achievements] Okaya Overpass

"Rack scaffolding" allows for efficient scaffolding installation work even during limited working hours when the tracks are closed!

We would like to introduce our construction achievements for the repair work on the Okaya Viaduct (a prestressed concrete five-span continuous frame box girder bridge) located between Okaya Junction and Okaya Interchange on the Nagano Expressway. Since the intersecting property is the JR Chuo Main Line, we adopted the "rack scaffolding," which allows for efficient scaffold installation even during limited working hours when the tracks are closed. Please feel free to contact us if you have any inquiries. 【Overview】 ■ Location/Prefecture: Nagano Prefecture ■ Client: East Japan Railway Company Nagano Branch ■ Construction Company: Tohoku Steel Industry Co., Ltd. ■ Start of Use: October 2015 ■ Local Workers' Experience with Rack Scaffolding: First time ■ Presence of Rack Scaffolding Handling Instructor: Yes *For more details, please refer to the PDF document or feel free to contact us.

[Scaffolding Construction Achievements] Isogo Elevated Bridge

[Scaffolding Construction Achievements] Isogo Elevated Bridge

The installation period for the suspended scaffolding on the municipal road can now be limited to just two nights of nighttime work!

We would like to introduce our construction achievements for the new construction work of the Isogo Elevated Bridge (Part 1) in the "Negishi Area" along National Route 357 (Wangan Road). The Isogo Elevated Bridge spans Yokohama City Road No. 181, and to shorten the period for the installation of the suspended scaffolding on this city road, we adopted the "rack scaffolding." At the construction yard beside the city road, we assembled and lifted a scaffolding that can cover the entire width of the city road (19m in the width direction × 24m in the bridge axis direction), which was later transported onto the city road during nighttime work. As a result of this adoption, the period for the installation of the suspended scaffolding on the city road was reduced to just two nights of nighttime work. This site was adopted not as a "mobile suspended scaffolding method," but as a method that "quickly constructs full suspended scaffolding by using rails to extend the scaffolding." *For more details, please refer to the PDF document or feel free to contact us.
