BACKGROUND OF THE INVENTION

When preparations are made for constructing a stem wall, two workers are typically needed to align inner and outer forms. The forms have to be at proper height in relation to each other, proper distance in relation to each other, and parallel. This is not an easy task, and, requiring two workers, is time consuming and costly. The present apparatus solves this problem with a two-piece apparatus with telescoping fit, enabling a single worker to quickly position inner and outer forms in relation to each other.

FIELD OF THE INVENTION

The concrete form tool apparatus relates to concrete forms and more especially to an apparatus providing for one worker to set proper spacing and alignment between an inner and an outer concrete stem wall form.

SUMMARY OF THE INVENTION

The general purpose of the concrete form tool apparatus, described subsequently in greater detail, is to provide a concrete form tool apparatus which has many novel features that result in an improved concrete form tool apparatus which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.

To attain this, the concrete form tool apparatus allows a single worker to correctly position inner and outer stem wall forms. The apparatus is ideally made of stainless steel but is also available in other materials, including plastics, polymers, aluminum, and alloys. The apparatus saves time and labor by allowing a worker to quickly position forms. The apparatus properly positions inner and outer stem wall forms in a parallel relationship. The apparatus also properly positions inner and outer stem wall forms in proper height relationship, accounting for differing form heights. Additionally, the apparatus positions inner and outer stem wall forms in a proper distance relationship. The apparatus positions inner and outer forms in a 6 inch spread or an 8 inch spread. Other embodiments are available for various construction situations wherein other form spreads are desirable and accommodated by the apparatus embodiments.

One embodiment provides a 1 9/16 inch spread between the short vertical member and the long vertical member of the inverted J-shaped outer form bracket. The first and second female tubes attached to the outer form bracket are ideally 9/16 inch inside diameter and 3¾ inches in length. The first and second female tubes are ideally about 2 inches apart. The first inner vertical member of the inner form bracket is ideally about 1 9/16 inches apart from the second inner vertical member. These dimensions provide for fit of forms such as 2×4/s and 2×6's.

Various other embodiments, some more basic, are provided. More than one means of affixing the male tube within the female tube is provided. Flat stock may be substituted for the female tubes and the male tube. The handle location is not limited to the inner form bracket.

Thus has been broadly outlined the more important features of the improved concrete form tool apparatus so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

An object of the concrete form tool apparatus is to properly position inner and outer stem wall forms.

Another object of the concrete form tool apparatus is to properly position inner and outer stem wall forms with only one worker.

A further object of the concrete form tool apparatus is to save time and labor.

An added object of the concrete form tool apparatus is to properly position inner and outer stem wall forms in a parallel relationship.

And, an object of the concrete form tool apparatus is to properly position inner and outer stem wall forms in proper height relationship.

DETAILED DESCRIPTION OF THE DRAWINGS

With reference now to the drawings, and in particular FIGS. 1 through 5 thereof, the principles and concepts of the concrete form tool apparatus generally designated by the reference number 10 will be described.

Referring to FIGS. 1 and 3, the apparatus 10 partially comprises an inverted J-shaped outer form bracket 20. The outer form bracket 20 partially comprises the downwardly positioned short vertical member 24. The horizontal member 26 has a first end 27a spaced apart from a second end 27b. The horizontal member 26 first end 27a is attached perpendicularly to the short vertical member 24. The long vertical member 28 is attached perpendicularly downward to the horizontal member 26 second end 27b. The long vertical member 28 is parallel to the short vertical member 24. The long vertical member 28 has a length. The first female tube 30 is attached perpendicularly inwardly to about a midpoint of the length of the long vertical member 28. The second female tube 32 is attached perpendicularly inwardly to the long vertical member 28. The second female tube 32 is spaced apart from and parallel to the first female tube 30. The pair of identical spaced apart vertical tube orifices is disposed through each female tube. The tube orifices comprise the first tube orifice 34 and the second tube orifice 36.

Continuing to refer to FIGS. 1 and 2, the inner form bracket 40 partially comprises the horizontal male tube 42. The male tube 42 is removably and selectively inserted into the first female tube 30. The male tube 42 can also be removably and selectively inserted into the second female tube 32. A pair of spaced apart identical orifices is disposed vertically through the male tube 42. The orifices comprise the first orifice 43a and the second orifice 43b. The pair of identical pins 38 is removably selectively inserted through the first orifice 43a and the second orifice 43b. The identical pins 38 are further inserted selectively and removably through the first tube orifice 34 and the second tube orifice 36 of the first female tube 30. The pins 38 may also be selectively and removably inserted through the second female tube 32. The first inner vertical member 44 is affixed atop the male tube 42. The second inner vertical member 46 is affixed outwardly to the end of the male tube 42. The second inner vertical member 46 is parallel to the first inner vertical member 44. The cylindrical handle is affixed outwardly to the second inner vertical member 46.

Referring to FIG. 1, the apparatus 10 is removably positioned over an existing outer 14 and existing inner form 12 in order to position the forms in correct relationship.

Referring to FIG. 4, the apparatus is fitted to the inner form 12 and the outer form 14. The male tube 42 is inserted almost fully into the first female tube 30. The inner form 12 is of a shorter height than the outer form 14. Inserting the male tube 42 into the first female tube 30 positions the top of the forms at the same height. The forms are therefore held parallel to each other, positioned at the same height, and spaced 6 inches apart.

Referring to FIG. 5, the example is made with the inner form 12 and outer form 14 having identical heights. The male tube 42 is therefore inserted into the second female tube 32 in order to position the tops of the forms at the same height. Further, the forms can be positioned either 6 inches apart or 8 inches apart. The 8 inch form spread is secured by inserting the pin 38 through the second tube orifice of the second female tube 32 and the first orifice 43a of the male tube 42.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the concrete form tool apparatus, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the concrete form tool apparatus.

Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the concrete form tool apparatus may be used.

Therefore, the foregoing is considered as illustrative only of the principles of the concrete form tool apparatus. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the concrete form tool apparatus to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the concrete form tool apparatus.
