Publication number: 20060016956Abstract: A brace for securing concrete forms to a base has first and second triangularly-shaped sidewalls and a back wall extending between corresponding side edges of the sidewalls. A peripheral flange extends outwardly from the side edges of the sidewalls and the ends of the back wall and has apertures for facilitating fastening of the brace to the concrete forms and a casting surface. Advantageously, the brace can be formed as a unitary, molded component. A battering wedge is selectively attachable to the side edges of the sidewalls and cooperates with the brace to facilitate tilting the concrete form at an angle to the casting surface. The battering wedge is selectively frangible to permit use with braces of varying size.Type: ApplicationFiled: July 22, 2004Publication date: January 26, 2006Applicant: Aztec Concrete Accessories, Inc.Inventors: Clifford Bennett, Kenneth Lee

Publication number: 20020145093Abstract: A brace for use in tilt-up construction is disclosed. The brace includes a bottom surface and a vertical side surface. The bottom surface of the brace is affixed to a permanent horizontal surface (e.g., a slab) in a manner that allows the brace to be removed without damaging the permanent horizontal surface. The vertical side surface of the brace is attached to a concrete pour form. The bottom surface of the brace is affixed to the permanent horizontal surface using an adhesive. Alternatively, a shoe is attached to the permanent horizontal surface and the brace sits in the shoe. A flange is releasably securable with the brace to batter the form when the flange is place in contact therewith. Alternatively, the shoe has an upwardly extending inclined ramp that is operable to orient the brace so that the vertical side surface of the brace is disposed at a battering angle to batter the form.Type: ApplicationFiled: April 11, 2002Publication date: October 10, 2002Applicant: Aztec Concrete Accessories, Inc.Inventors: Scott Shaw, Dale Robert Haslem, Ken Lee, Steve Wilbur, Clifford D.

Patent number: 6089522Abstract: The present invention is an improved high chair which positions and supports reinforcement members at a desired distance from a surface. The high chair has a body with a lower base portion, an upper connecting portion and an upper support surface. One or more supporting feet are preferably attached to the lower base portion to provide for secure support of the chair on a variety of surfaces, including harder surfaces such as a concrete mold or softer surfaces such as graded soil. The upper support surface includes a support structure configured to hold the reinforcement bars in a stationary position. The upper support surface also includes a plurality of holes which allows a head piece to be mounted to the chair. The head piece allows the height of the chair to be readily adjusted.Type: GrantFiled: October 2, 1998Date of Patent: July 18, 2000Assignee: Aztec Concrete Accessories, Inc.Inventors: Dale Haslem, G.
