Abstract:
An improved concrete form duct chair and method of forming concrete structures. The concrete form duct chair has a generally flat polymer or steel body with several pre-stressing strand duct sized apertures passing through the body, as well as four or more alignment legs projecting from the body, the alignment legs and body dimensioned and configured to extend for a total width approximately equal to such cross sectional width of such concrete form and thus hold the concrete form duct chair in position against the walls of the form. Concrete access apertures passing through the body allow concrete to pass therethrough during pouring operations. A method embodiment of the invention teaches pouring of concrete structures with pre-stressing ducts passing therethrough using the device of the invention to retain the pre-stressing ducts in alignment within the concrete form.
