In the conventional steel frame foundation method, after constructing a reinforced concrete foundation, steel columns of the superstructure are connected to that foundation. This method has issues such as the need for a large amount of excavated soil and backfill soil after the foundation is completed to secure the workspace for formwork, rebar work, and concrete work, as well as poor workability due to the confined working area. To solve these problems, a pile head connection method (rigid pile joint method) combining precast piles, steel foundation beams, and steel columns has been developed, and it has obtained architectural technical performance certification from the Japan Building Disaster Prevention Association. This method targets a foundation form that uses a steel beam for the foundation beam of the superstructure and a precast pile for each steel column, allowing for the omission of formwork, rebar, and concrete work by connecting the precast piles and steel columns with special steel fittings, thus enabling cost reduction and shortening of construction periods.

• Pile and foundation work

The "Kyōkin Tarō Method" is a construction method for place-driven piles that processes and assembles rebar cages "without welding." The tie bars are made into spiral bars and automatically wrapped around the main bars, with binding done manually, resulting in rebar cages with excellent strength, rigidity, and dimensional accuracy. 【Features】 ■ High strength ■ High quality ■ Improved workability ■ Shortened construction period ■ High seismic resistance ■ Construction in narrow spaces *For more details, please download the PDF or contact us.
