Project Summary: this project is a vocational school building and located at Shinjuku Tokyo Japan. The tower is of 203M high enclosed with curtain wall of 30000 sq.m.
Architectural Effect: The exterior wall of this project is of exposed frame unitized glass curtain wall with “V” shape structure. The white decorative trim cover just like silk engird around the building,which makes the entire building looks like a cocoon. The “cocoon” has become one of the most representative building in the world by its unique exterior appearance.
Structure feature：The entire unit is organically separated into 3 sub-units for fabrication, assemble and transportation. Then assemble and install these sub-units integrally. It can be considered as an innovation of curtain wall technology.
Performance Characteristic: This curtain wall adopts shifted structure in three dimensions to increasing the adjustive capability, use the monodirectional drain plug to increase the watertight and airtight performance, and adopt splice connecting to strengthen the connecting rigidity and achieve the reliable connection between dihedral angels of allotypic units.
