  • Concrete sandwich wall insert
    Patent number: 8490352
    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).
