Abstract
Abstract A top rail tie bracket for concrete forms for eliminating the usual additional wooden rail required across the top of the top rail of the form for bracing the wedging element of the top snap tie rod. A reusable T-shaped bracket is provided, one leg of which abuts the top rail and the other leg serves as a back-up support to overcome the tensioning action of the wedge on the top snap tie rod. This eliminates the necessity of the additional top rail.

Claim 1
Independent Claim
197 words
In combination with a concrete wall forming form comprising a pair of vertical, spaced parallel form panels with horizontal top rails engaging the outer top ends thereof and a snap tie rod extending across the top of the form and top rails and having a head at each end; the improvement comprising a bracket of T-shaped cross section on each end of said rod, each bracket having right angular legs thereof snugly engaging the top and outer sides of the corresponding top rail and having holes therethrough for driving nails into said corresponding top rail, each bracket also having a central hole just above the top surface of the leg engaging the top side of the corresponding top rail, and a wedge between the outer vertical surface of at least one of said brackets and the corresponding head having a keyhole opening and elongated slot for guiding the corresponding head of said tie rod while driving said wedge downwardly in sliding engagement with the outer vertical surface of said at least one bracket so as to apply tension to the tie rod with back-up support by the remaining right angular leg of said at least one bracket.
