岡部 Company Profile

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.

We are pleased to announce that our company’s product, "Blaster Z," has won the Good Design Award 2014. The "Blaster Z" is an innovative brace hardware that utilizes the strength of braces supporting wooden structures while simultaneously providing flexibility and resilience. Its most notable feature is the V-shaped slit incorporated into the main body. This V-shaped slit successfully makes effective use of the buckling phenomenon, which is often considered taboo in construction. As a result, it has become possible to satisfy both a certain level of strength and resilience simultaneously. [Judges' Evaluation] Since the Great East Japan Earthquake, a variety of seismic, vibration control, and seismic isolation methods have been proposed for traditional wooden frame construction. However, many of these systems are overly complicated, require specialized and difficult construction methods, and are expensive, which has hindered their widespread adoption. In contrast, this construction method, which involves simply making partial cuts in steel plates and bending them, offers a straightforward system that connects the frame members with just nails, making it a highly accessible product that can be easily implemented in standard carpentry work.
