Abstract: Improved concrete form insert assemblies (20) are provided for use in the construction of thermally insulated poured concrete sandwich wall structures (22). The insert assemblies (20) include a central sheet (32) of insulative material such as synthetic resin foam, which is preferably encapsulated by a sheath (78) to enhance the structural integrity of the sheet (32). A pair of reinforcing bar assemblies (46, 48) preferably made up of welded-together horizontal and vertical bars (50, 52) are respectively positioned adjacent the side surfaces (34, 36) of the sheet (32). The bar assemblies (46, 48) are secured to sheet (32) by means of connector elements (54) extending through the sheet (32) and presenting oppositely outwardly extending, apertured segments (56, 58).

Abstract: An assembly (20) for releasably interconnecting a pair of concrete form panels (22, 24) having adjacent, apertured walls (30) is provided which completely eliminates loose parts and significantly reduces panel setup and knock-down times. The assembly (20) includes an elongated pin (38) axially shiftable between extended and retracted positions, as well as an elongated connection arm (88) of length to bridge the adjacent walls (30) and engage the remote surface of the wall (30). An operating mechanism (42) is operatively coupled with pin (38) and arm (88). A latch assembly (96) serves to releasably maintain the pin (38) and arm (88) in their respective positions. Preferably, the pin 38 is mounted on a body (36) shiftable along a track (46); the latch assembly (96) is also supported on the body (36) to insure that the operating mechanism (42) can be properly latched in the retracted and extended positions of the pin (38).
