  • Patent number: 8556535
    Abstract: A frame for installing strips of expansion joint material in freshly-poured concrete has an elongated spine around which other elements of the frame are assembled. Spaced retainers are attached along a spine side. A flat side panel extends along another spine side. A space formed between panel and retainer receives a strip of expansion joint material. Notches are spaced along the bottom edge of side panel and serve as guides for spaced nails driven through the joint material. Spaced stakes are driven into the ground to hold the frame in place as concrete is poured around the frame. Handles are attached to the spine for removal of the frame after the concrete has been poured. The nails, immersed in the fresh concrete, hold the strip in place as the frame is lifted from the concrete and the strip remains in place within the concrete.
