  • High chair spacer
    Patent number: 4080770
    Abstract: A high chair spacer, for use in concrete construction and casting, for locating reinforcing rods and other elongated bodies to be placed in the concrete, such as cables, pipes or ducting, and a method for making such a spacer, which consists of a plastic base and a metal wire standoff spacer member and a plastic standoff member supported in the base. The metal member provides the strength necessary for receiving and supporting reinforcing rods but is protected from corrosion by the tough plastic base. The metal member is received in tubular-shaped recesses in the base. The high forces transmitted to the base by the metal member, and overturning lateral forces are resisted by the specifically designed base. The plastic standoff members straddles the metal member and is secured in cooperating slots in the base. Tabs may be provided on the base for positively attaching it to supporting formwork structure.
