Abstract
A joint clamp particularly useful in joining braces of the type used temporarily to brace concrete slabs employed in tilt-up construction. The clamp can be installed onto a cylindrical brace without the employment of tools and without access to either end of the brace. It comprises, as a principal component, a tubular member that defines an opening having a generally cylindrical cross-section corresponding to the cross-sectional size of the brace. The wall forming the cylindrical opening is formed with a helically extending slot having a width, in an oblique direction, slightly larger than the cylindrical brace so that the clamp can be placed on the brace in an oblique position and then twisted into parallelism with the brace to snugly embrace the brace. The tubular member carries one or more secondary clamps for securing cooperating secondary brace members thereto.
