Abstract

A stamped, sheet metal, form connector connects two concrete form boards together in end-to-end abutting relationship in one embodiment. In another embodiment, the connector connects two form boards in overlapping relationship. In a third and fourth embodiment, the connector connects two form boards at an inside and outside corner, respectively. Double headed nails fasten the connector to the form boards, allowing for easy removal without damage to the forms. The connector is inexpensive to manufacture, and is simple and convenient to use.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to the masonry field, especially to the art of laying up forms in which concrete footings are poured. Forms for concrete footings are usually made of dimensional lumber or heavy plywood panels, or may even be manufactured aluminum panels. Where these lengths of lumber or panels are laid up end to end, they must be joined together in a fixed relationship, so that the concrete will not blow out the joint in the forms.

[0002] A typical method of joining form boards in end to end relationship is to nail a splice board over the joint. While this method can result in a satisfactory joint, it is an inefficient method in that wood must be cut to length and applied over the joint with sufficient nails to secure the splice. When such a splice is removed, as the forms are taken up, the forms are often damaged and cannot be reused.

[0003] Another method of joining forms at corner joints is to nail through the face of one form boar...

Embodiment Construction

[0014]FIG. 1 shows a first embodiment of the form connector 1 in use connecting two form boards 7 and 8 in an end-to-end abutting relationship. Form connector 1 consists of a sheet metal body having an outside portion 2, a top portion 3, and an inside portion 4. Form connector 1 sits atop the joint between two form boards 7 and 8, spanning the joint therebetween. Outside portion 2 extends downwardly from the top of the form boards and extends over a portion of the outsides of the form boards. Top portion 3 is connected to the outside portion 2 and extends across the upper surface of the form boards, also spanning the joint therebetween. Connected to the top portion 3 is an inside portion 4, which extends downwardly from top portion 3 and extends over a part of the inside surface of the form boards 7 and 8. Nail holes 5 are strategically placed on the outer portion 2 and top portion 3 allowing for double headed nails 6 to pass therethrough, securing the connector 1 to the form boards...
