Abstract
Abstract A column form support system and method are set forth encasing steel in concrete. Included are support members which are affixed to the steel and extend outwardly therefrom. A concrete form is exerted about the steel, the support members being adjustable to bear against, and support and align the form relative to the steel. Concrete is poured into the form to encase the steel, the support members maintaining the proper alignment of the form. After the concrete has hardened, the form is disassembled.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A form about an upstanding column for receiving concrete including: interconnected form panels disposed about said column to define a form to receive concrete; and means for supporting and adjustably spacing the panels about the column without attachment thereto, the supporting means including, at least one stud affixed to and projecting from the column to support a corresponding form panel, and a bearing member removably coupled to and adjustably positionable at the end of each stud, each bearing member having a base spaced from the column, the bearing member bases at each side of the column arranged to be coplanar, said form panels bearing against the bearing member bases to support the panels in the planes defined by said bases.
Claim 2
Dependent Claim
120 words
A form about an upstanding column for receiving concrete including: interconnected form panels disposed about said column to define a form to receive concrete; and means for supporting and adjustably spacing the panels about the column without attachment thereto, the supporting means including, at least one stud affixed to and projecting from the column to support a corresponding form panel, and a bearing member removably coupled to and adjustably positionable at the end of each stud, each bearing member having a base spaced from the column, the bearing member bases at each side of the column arranged to be coplanar, said form panels bearing against the bearing member bases to support the panels in the planes defined by said bases.
Claim 3
Independent Claim
147 words
A method for forming a concrete column encasing a steel member comprising in sequence: attaching at least one stud to the steel member to project outwardly from the member to support a corresponding form panel; detachably coupling a bearing member at the end of each stud, each bearing member including a base remote from the member; positioning the bearing members at each side of the steel member to a position whereat the bases are coplanar; erecting form panels to disconnectedly bear against said bases without attachment thereto to define a form, the panels aligned into the planes defined by the member bases; pouring concrete into said form comprised of the form panels supported by, but not attached to the bearing members, to encase the steel member, studs and bearing members; and disassembling said form panels when the concrete has hardened and removing said bearing members for reuse.
