In an alternate embodiment, the short vertical member 130 is coupled to the first edge 122 of the horizontal member 120 and the long vertical member 140 is coupled to the second edge 124 of the horizontal member 120.

[0021] As further shown in FIG. 2, the short vertical member 130 preferably comprises a first plurality of holes 136 configured to removably attach a first form board 132 to the short vertical member 130 using a plurality of fasteners 160. The first form board 132 is preferably located on a short inside surface 134 of the short vertical member 130 such that the width of the first form board 132 is flat against the short inside surface 134 of the short vertical member 130. The plurality of fasteners 160 are inserted through the first plurality of holes 136 on the short vertical member 130 into the first form board 132.

[0022] As further shown in FIG. 2, the long vertical member 140 preferably comprises a second plurality of holes 146 configured to removably attach a second form board 142 to the long vertical member 140 using a plurality of fasteners 160. The second form board 142 is preferably located on a long inside surface 144 of the long vertical member 140 such that the width of the second form board 142 is flat against the long inside surface 144 of the long vertical member 140. The plurality of fasteners 160 are inserted through the second plurality of holes 146 on the long vertical member 140 into the second form board 142. The plurality of fasteners 160 are preferably nails or screws, however, other types of fasteners not enumerated herein may be considered.

[0023] The stem wall bracket 110 is configured to hold a first form board 132 that is a standard two inch by six inch (2″×6″) lumber. Additionally, the stem wall bracket 110 is further configured to hold a second form board 142 that is a standard one inch by ten inch (1″×10″) lumber. Preferably, the stem wall bracket 110 holds the first form board 132 parallel to the second form board 142. Preferably, the stem wall bracket 110 positions the first form board 132 on what will be the inner stem wall side and positions the second form board 142 on what will be the outer stem wall side. The sizes of the first and second form boards are specified for example purposes only, the stem wall bracket 110 is configured to accommodate other sizes of lumber for the first and second form boards as dictated by the size and width of the resultant stem wall.

[0024] As further shown in FIGS. 1-4, the horizontal member 120, the short vertical member 130, and the long vertical member 140 are all preferably relatively flat and rectangular. Preferably, the stem wall bracket 110 is comprised of steel, or other stiff material such that the stem wall bracket 110 won't bend or move during use.

[0025] As further shown in FIG. 2, the stem wall bracket 110 preferably further comprises a pin holder 150 configured to extend downward from the horizontal member 120 and hold a horizontally placed rebar 158. The pin holder 150 preferably comprises a vertical portion 152 configured to removably attach to the horizontal member 120 and a horizontal portion 154 extending away from the vertical portion 152.

[0026] In another embodiment, the pin holder 150 comprises a plurality of horizontal portions 154 spaced along the vertical portion 152. In this embodiment, the pin holder 150 may retain a plurality of horizontally oriented rebar 158. Additionally, in this embodiment, the plurality of horizontal portions 154 extend away from the vertical portion 152 along the same plane such that after pouring the concrete for the stem wall, the pin holder 150 is rotated at least ninety degrees to be removed, thus releasing the plurality of horizontally oriented rebar 158 into the concrete. In another embodiment, the plurality of horizontal portions 154 may extend away from the vertical portion 152 in any direction.

[0027] The vertical portion 152 of the pin holder 150 preferably comprises a top 156 configured to prevent the pin holder 150 from falling through a second hole 128 in the horizontal member 120. The top 156 is preferably configured to be larger than the second hole 128 in the horizontal member 120.

[0028] As shown in FIG. 4, the horizontal member comprises a first hole 126 for configured to allow standard sized rebar 158 to fit through the horizontal member 120 and down in between the first form board 132 and second form board 142 in a vertical position. The horizontal member 120 further comprises a second hole 128 configured to allow the pin holder 150 to fit down through the horizontal member 120.

[0029] As shown in FIG. 5, a stem wall bracket system 100 comprises a first form board and a second form board positioned parallel to each other and a plurality of stem wall brackets 110 wherein the short vertical member 130 is removably attached to the first form board 132 and the long vertical member 140 is removably attached to the second form board 142. Preferably, the plurality of stem wall brackets 110 are spaced evenly along the length of the first and second form boards. The first and second form boards are set-up such that the width of the first and second form boards are vertical.

[0030] A method of using a stem wall bracket, comprising the steps of placing a first form board along an inner perimeter of a stem wall; attaching a stem wall bracket to the first form board using a plurality of fasteners, wherein each stem wall bracket comprises a horizontal member, a short vertical member extending downward from a first edge of the horizontal member, and a long vertical member extending downward from a second edge of the horizontal member, wherein the first edge is opposite the second edge; and attaching a second form board to the stem wall bracket using a plurality of fasteners to form an outer perimeter of a stem wall.

[0031] The method further comprises the steps of arranging rebar in between the first form board and second form board, inserting a pin holder through a hole in the horizontal member of the stem wall bracket, pouring concrete in between the first form board and second form board, and removing the pin holder from the stem wall bracket by turning and pulling the pin holder out of a hole in the horizontal member.

[0032] Finally, after the concrete stem wall has cured or hardened, the last step is removing the plurality of fasteners to remove the stem wall bracket from the first form board and second form board.

[0033] Although the present invention has been described by way of example, it should be appreciated that variations and modifications may be made without departing from the scope of the invention. Furthermore, where known equivalents exist to specific features, such equivalents are incorporated as if specifically referred to in this specification.
