Latest Patents
One of Akihama's latest patents is a method of making a window frame for concrete wall panels. This innovative approach involves creating a combination of concrete panel walls, concrete window frames, and concrete sash glazing frames. 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 with the panel wall. The sash members are designed to fit around a window pane located in interior grooves, and sealing means are incorporated to ensure a condensation-resistant, water-tight, air-tight, heat, and fire-resistant closure.
