The "Formwork One-Piece Tightening Method" has won the Special Jury Award at the 54th Japan Industrial Technology Awards.

岡部 岡部
The one-bolt formwork method is a new construction technique in formwork work, the first in about 70 years. Our company, which developed the conventional method (the formwork retention method combining round separators, form ties, and special washers) that has been in use since 1951, along with our joint development partners, has taken on the challenge of developing the one-bolt formwork method. This method reduces the workload of aging skilled workers and less experienced construction workers. Additionally, we have developed a pipe joint that supports the cut ends and ends of pipes, as well as a new type of formwork fastening device called "Next Tie." These developments have led to improved productivity through weight reduction and simplification, ensured safety, and provided concrete solutions to on-site challenges, earning high praise for contributing to society. Okabe Corporation (Headquarters: Sumida-ku, Tokyo, Representative Director and President: Hirohide Kawase, hereinafter referred to as "the Company"), which develops construction-related products and marine businesses, has received the Special Award from the 54th Japan Industrial Technology Award for the "one-bolt formwork method" developed in collaboration with Kajima Corporation, Marukyu Co., Ltd., and Kusunoki Construction Co., Ltd. This is the first time our company has received the Japan Industrial Technology Award.

NETIS Registration: Reducing Workforce at Construction Sites and Improving Work Efficiency with the "Single Formwork Tightening Method"

Storage space, material yard, and reduced transportation volume contribute to CO2 reduction!

The "single clamp formwork method" has made it possible to secure with one aluminum pipe instead of the previous method of using two steel pipes as a pair. With the optimally designed camber-shaped aluminum pipe, pipe joints for connections, and dedicated fastening hardware called NexTie (form tie), tightening can be completed with just one outer batten. The number of pipes is halved, the weight per pipe is reduced, and the weight of conventional methods is reduced by 70%, easing the labor required for lifting operations. 【Features】 ■ The number of pipes used is reduced from two to one, halving the amount ■ Assembly, disassembly, and reconfiguration are sped up ■ The aluminum pipe is about 60% lighter than a single steel pipe ■ Reduction in transportation quantity leads to a decrease in CO2 emissions *For more details, please download the PDF or feel free to contact us.

"Civil Engineering Watching - Infrastructure Encyclopedia: Collection of Civil Engineering Structures" is a portal site for images and information about civil engineering structures that form social infrastructure facilities. We have recently published photos and articles about the "Saale Valley Bridge." The "Saale Valley Bridge" was constructed at the border between Saxony-Anhalt and Thuringia, in Bad Kösen, Naumburg. Boasting an impressive height of up to 60 meters, this structure spans a total length of 1.2 kilometers and a width of 12.5 meters, harmoniously blending with the surrounding landscape designated as a nature reserve. In addition to the "Saale Valley Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.

  • NEW
  • PRODUCT

We have introduced the Majesta Fragrance commercial diffuser to a fitness gym located in the city. Gyms and sports clubs tend to trap sweat and humidity, making them spaces where odor issues can easily arise. That’s why "scent design (branding)" that dramatically changes the overall impression of the space is highly effective. - The diffuser being used is the [MF-01]. It is a stylish tower-type diffuser available for a monthly fee of 8,800 yen (tax included). This model is space-saving and blends well with any interior. - The scent being diffused is [Forest Green]. It is a refreshing fragrance that blends the crispness of bergamot with the natural scent of green, creating a clean and pleasant atmosphere. It enhances concentration during exercise while providing a refreshing and comfortable space. A free trial installation is available. "I don’t know what scent would suit my gym." "I want to try out the different scents available." For such stores, Majesta Fragrance offers a free trial installation. If you are considering space branding or odor control, please feel free to contact us.
