  • Publication number: 20080022618
    Abstract: A system for holding poured concrete in a desired shape until it sets is disclosed. The system can include a plurality of forms having two opposing end sections. Each of the end sections has an end bracket attached to it. A plurality of footing stakes are used to connect the end brackets together such that the forms maintain the desired shape. At least one whaler bracket may be secured to a top of the forms to maintain the spacing between them. A skin panel can be used to bridge gaps between forms. Bulkhead brackets can be attached to the ends or centers of the forms and secured to allow end walls to be created where desired. Vertical footing panels can also be used to pour concrete onto adjoining inclined surfaces.

  • Publication number: 20070045491
    Abstract: A grade bracket for use with concrete form systems is disclosed. In one embodiment, the grade bracket forms part of a concrete form system that includes a plurality of form components, including straight forms, curved radius forms, and skin panels for interconnecting form components. The form components are assembled atop a ground surface and are configured to define a volume for containing poured concrete. Grade brackets for supporting the form components at a desired grade above the ground are used. Each grade bracket includes a body, a form support member, and a grade knob. The form support member attaches to the body and includes a bracket portion that supports the form component. The grade knob includes an eye-bolt. A stake secured in the ground is selectively engaged by the eye-bolt of the grade knob such that the grade bracket is maintained at a desired position on the stake.
