The 41st Meritorious Service in Engineering Award was announced in 2021, sponsored by the Association of Engineers, and the obayashi group’s project was awarded in two categories. The Engineering Merit Award is recommended and decided by companies and organizations in various fields such as generalists, engineering, steel, and shipbuilding, and is presented to groups and individuals who have contributed to the development of the industry of engineering. this year, 14 group prizes were selected.

Construction Short Period Replacement Project Team for Aging Floor Plates on Fast Growing Highways (Obayashi Company)
In the work of replacing the concrete floor plate of the aging highway, we developed and applied “Slim Fastener” using ultra high strength fiber reinforced concrete (UFC: ultra high strength fiber reinforced concrete) as the filling material of the prefabricated floor plate joint, and achieved shortening of the construction process and improving the quality of the joint.
Using Obayashi’s “Slim Cleats” developing technology, which demonstrates high strength without thermal hardening, UFC eliminates the need for additional strengthening muscles in the joints and reduces the binding width to 50% of the conventional method. A multiple shear wrench with an uneven shape is provided on the joint surface to strengthen the adhesion between the prefabricated floor plate and the infill material, preventing the joint surface from opening. increased durability of joints.
THIS DEVELOPMENT AND APPLICATION HAS BEEN HIGHLY EVALUATED TO HELP PROMOTE ENGINEERING, SUCH AS THE PIONEER OF LARGE SCALE CFU MANUFACTURING, TRANSPORTING, PUNCHING AND CURING IN THE FIELD, AND DOING. THAT THIN BINDINGS MAY BE APPLIED IN THE FUTURE.
The obayashi group will continue to help solve social problems by working to create a city where people can live safely not only in Japan but also abroad through engineering that combines technology and wisdom.
