Taiyo Kogyo Completes Large Roof Using Membrane and Space Truss Structure 'TM Truss'

Taiyo Kogyo Corporation has completed the construction of a large roof over the entrance plaza at the Roadside Station and River Station 'Mizu no Sato Sawara' in Katori City, Chiba Prefecture, as part of a renovation project. The new structure utilizes 'TTR' (TAIYO TRUSS ROOF), combining a membrane roof with the geometric steel frame of the 'TM Truss' system. This innovative approach allows the roof to be built with approximately half the weight of conventional steel structures. By receiving loads across the entire roof surface, it prevents localized stress concentration, ensuring high rigidity and load-bearing capacity while creating a bright, column-free space with a large span. The lightweight design reduces the burden on columns and foundations and easily accommodates complex, curved shapes, resulting in a highly aesthetic and safe design suitable for areas with heavy foot traffic. The facility will serve as an all-weather space for events and resting, and crucially, as a regional disaster prevention base during emergencies. The membrane construction took place from February to March 2026.
