  • Patent number: 8443517
    Abstract: An expansion joint bracket retains an expansion joint board in a concrete installation. The expansion joint bracket may include a base member having multiple nail holes for securing the bracket to the earth (or sand or gravel put down prior to pouring concrete there upon). First and second board support members may run perpendicular to the base and parallel to each other to hold the expansion joint board in place. Gussets, typically triangular shaped gussets, extend from the board support members to the base member. The expansion joint brackets may be disposed every 12-24 inches on the expansion joint board and concrete may be poured over the expansion joint brackets, resulting in a quick and simple concrete installation.
