Abstract
A combination concrete panel wall, concrete window frame, and concrete sash glazing frame. The sill, lintel, and jambs of the window frame are fiber-reinforced concrete extrusions which are cut to length and cemented together. The hardened frame is placed in a concrete panel molding frame to locate and define a window opening. The concrete panel wall grout is then poured and dovetail-type mortise and tenon joints are precast in the exterior faces of the window frame which abut the poured concrete wall panel plastic grout, to permanently mold and interlock the window frame to the panel wall. The sash members are also reinforced concrete extrusions which are cut to length, cemented together, and fitted about a window pane which is located in interior grooves in the sash members and then glazed. An elastoplastic seal interconnects the sash to the window frame to provide a condensation-resistant, water-tight, air-tight, heat and fire-resistant concrete wall closure.
