Description
- This application claims benefit of provisional application Ser. No. 60/812,889 filed on Jun. 12, 2006, entitled “Stay-in-place concrete footing forms”; and provisional application Ser. No. 60/879,384 filed on Jan. 9, 2007, entitled “Stay-in-place concrete footing forms”.
- Not applicable.
- The present invention generally relates to forms for pouring concrete footers and more particularly to a form system that also provides water drainage as a continuous drain tile.
- Stay-in-place concrete footing forms are commercially available and used in the home construction industry. One such form system by Alton F. Parker is based on hollow forms that function to also drain water (see U.S. Pat. Nos. 5,224,799, 5,210,162, for example). Another such form system by Patrick S. Pawlicki uses a dovetail in one side of the form for permit the forms to be staked to the ground. An elaborate connection system is proposed to join adjacent such forms (see U.S. Pat. No. 5,015,117).
- Despite the availability of these concrete footer form systems, there still is a need in the art for improvements thereto. The present invention is one such improved concrete footer form system.
- A stay-in-place concrete footings form is used for forming a concrete footing between a spaced-apart pair of the stay-in-place concrete footings forms. Each concrete footing form is elongate and has a cavity inside the form. Each form has a pair of elongate sides wherein openings are formed in the elongate sides to permit water to flow into the cavity. Each form has a dovetail pin or dovetail slot formed along the lengthwise extent of both sides of the form. The dovetails permit clamps, having a mating dovetail slot or dovetail pin, to be clamped to the form for anchoring the form to the ground with a stake carried by the clamps.
- Advantages of the present invention include the ability to weep water from the soil surrounding the forms by the hollow space within each form. Another advantage is the ability to be staked into the ground via clamps designed to mate with the dovetails formed along the lengthwise extent of each form. These and other advantages will be readily apparent based on the disclosure set forth herein.
- For a fuller understanding of the nature and advantages of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

FIG. 13 is an end view of two stay-in-place concrete footings forms stacked atop each other; -
FIG. 14 is a partial perspective view of a lock for securing the two forms inFIG. 13 together using their dovetails; -
FIG. 15 shows the placement of rebar between two adjacent forms with a mask or clip capturing the rebar; -
FIGS. 16-18 show additional rebar mask or clip designs; and -
FIG. 19 is a simplified end view of adjacent, spaced-apart forms similar to those shown inFIG. 15 , but with a metal spring rebar clip. - The drawings will be described in further detail below.
- Referring initially to
FIG. 1 , a section of a stay-in-place concrete footings form, 10, is shown in perspective view.Form 10 is of thin-wall construction with a pair of hollow cavities, 12 and 14, separated by an elongate central wall, 16, which provides additional structural integrity. Along the lengthwise extent of both sides ofform 10 are weep or draining slots, exemplified by a slot, 18. Such slots permit water that accumulates and/or is present adjacent toform 10 to drain intocavities - It will be understood that the contractor will use a pair of such disclosed forms spaced-apart a suitable distance for pouring concrete between such spaced-apart forms for forming a conventional concrete footer, typically reinforced with rebar or other reinforcement. The disclosed forms are stay-in-place in that they are not removed after the concrete footer cures.
- In order to ensure that
form 10 stays in place before, curing, and after the concrete footer is poured, a pair of dovetails slots, 20 and 22, is formed along the lengthwise extent of both sidewalls ofform 10. Such dovetails can be used in connection a mating dovetail pin carried by a clamp, as disclosed in U.S. Pat. No. 5,015,117, cited above, in order to attached a stake driven into the ground and carried by the clamp. The precise shape of the dovetail pins and slots is not important, as common dovetails, lap dovetails, or other mating configuration can be used for connection purposes, as disclosed herein. - The dovetail pin or slot along the concrete footer side of the disclosed forms can be “locked” to the concrete footer, which surrounds a dovetail pin or fills a dovetail slot. Such positive locking may even dispense with the need for the clamps and stakes. The disclosed concrete footings form design, however, permits the use of conventional clamps and stakes along with the concrete lock to ensure that the form stays in place during the concrete pour, during the curing of the concrete, and after the concrete footer cures.
- Referring now to
FIG. 2 , a form, 30, is seen to carry a pair of dovetail pins, 32 and 34, along its lengthwise extent. Again, on such dovetail pin is locked to the concrete whileopposite dovetail pin 34 can be secured to a clamp designed with a mating dovetail slot.Form 30 also uses holes to accommodate water to flow to its interior. Slots, holes, or apertures of any configuration, then can be formed into the novel form in accordance with the disclosure set forth herein. - Referring now to
FIG. 3 , a form, 50, has a lengthwise dovetail slot, 52, and an oppositely disposed lengthwise dovetail pin, 54, for mating with the concrete on one side (either side) and for attaching to a clamp on the other (either) side.Form 50 uses both holes and slots. - Referring now to
FIG. 4 , dovetail slots, 56 and 58, have been formed along the top surface, 60, and bottom surface, 62, of a form, 64. Thus, the disclosed concrete footings form has the design flexibility of using dovetail pins, dovetail slots, or a combination of dovetail pins and dovetail slots in any combination on the sidewalls, top wall, and bottom wall.FIG. 5 shows a series of vertical slots, such as a slot, 66, formed in the sidewalls of the form, such as described in connection withFIGS. 1-3 . Again, the pattern of apertures and their shape is unimportant and can be left to the forms designer and/or manufacturer to implement. Of importance is that the disclosed stay in place forms function to move water away from the foundation after the structure is formed, while functioning as a conventional form for pouring concrete footers. Again, a unique multi-purpose form is disclosed. -
FIGS. 6-8 depict three different designs of splines, 68, 70, and 72, which splines are adapted to be placed in dovetails 56 and 58 ofform 64 illustrated inFIG. 4 . A variety of different spline designs will be readily apparent to the skilled artisan. -
