Latest Patents
One of Katsuta's latest patents is a method of making a window frame for concrete wall panels. This innovative approach involves creating a combination concrete panel wall, concrete window frame, and concrete sash glazing frame. The window frame's sill, lintel, and jambs are made from fiber-reinforced concrete extrusions that are cut to length and cemented together. The hardened frame is then placed in a concrete panel molding frame to define a window opening. The concrete panel wall grout is poured, and dovetail-type mortise and tenon joints are precast in the exterior faces of the window frame, permanently molding and interlocking it to the panel wall. The sash members are designed to fit around a window pane located in interior grooves, and sealing means interconnect the sash to the window frame, ensuring a condensation-resistant, water-tight, air-tight, heat, and fire-resistant closure.
