A method of making 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 fitted about a window pane which is located in interior grooves in the sash members and then glazed. Sealing means interconnect the sash to the window frame to provide a condensation-resistant, water-tight, air-tight, heat and fire-resistant concrete wall closure.

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.

Window frame for concrete wall panel

A vibration absorbing device to be secured between structural and non-structural members of a framed structure. An outer ring may be secured to a structural member and an inner ring is concentrically positioned within said outer ring and may be secured to a non-structural member. Radial spokes interconnecting the inner and outer rings are adapted to elasto-plastically deform when one ring is arcuately shifted relative to the other ring responsive to vibration of the inner and/or outer ring, thereby absorbing the energy of vibration.

Vibration absorbing device for structure

Curtain wall

A curtain wall building panel having a metal frame secured to the reverse side of a concrete panel with flexible anchors. A 3-D braid is formed in such a manner that non-metallic fibers are braided in the three directions at a pitch of 5 mm or more and have a self-supporting characteristic. The braid is embedded in the concrete panel and the front ends of the flexible anchors are secured to cell spaces in the 3-D braid. The curtain wall exhibits excellent bending strength, can be easily manufactured and can be used for exterior finish of multistory buildings. A method of making the building panel is also disclosed.
