FIELD OF THE INVENTION

This invention relates to a bracket assembly for facilitating the installation of a concrete wall on a concrete footing and a method of forming the wall. More specifically, this invention relates to a bracket assembly that can be used to position forms on a concrete footing for forming a concrete wall and the bracket assembly has a seal which will prevent moisture and/or water from seeping between the concrete wall and the concrete footing.

BACKGROUND OF THE INVENTION

In constructing a building, many foundation walls are formed by pouring concrete between interior and exterior wall forms. Typically, the first order of construction is to dig beneath the nominal surface of the ground, to a depth from which the building will be supported. In a mild climate, e.g. in a southern climate, where no basement is being included in the building, a typical digging depth is about 3 to 4 feet. In a colder climate, e.g. in a northern climate, the minimum depth is typically about 4 feet. Where a basement is being included, the digging depth is approximately 8 to 10 feet.

Once the excavation has been completed, the next order of activity is to form a concrete footing which generally extends about the perimeter of the building. The concrete footing is intended to underlie all other load-bearing portions of the building and can transmit the load of the building to the underlying soil. The dimensions of the concrete footing are about 12 to about 24 inches for a typical single-family home. The width of the footing is typically greater than the width of the upstanding foundation wall which extends upward therefrom. The concrete footing is wider so as to be able to spread the load of the building over a wider foot-print of soil than that which directly underlies the foundation wall. Another advantage of forming a wider concrete footing is that the footings are typically laid out in a more casual fashion than the foundation walls. This means that the footings do not have to exactly conform to the dimensions, angles, widths, etc. shown on the construction drawings.

Typically, after the concrete footing has set or cured for at least two days, one or more workers will have to spend several hours laying out and marking the precise locations where the building foundation walls are to be build on the footing. These locations are typically marked on an upper surface of the concrete footing with chalk, such as a powdered, colored chalked line, known in the trade as a “chalk line”. Powdered colored chalk is applied to a chalk line by a special tool. The line is then stretched taut directly over and adjacent to a length of the footing being marked by two construction workers. The taut line is then drawn or stretched slightly away from the footing and is allowed to snap back. The stretch in the chalk line causes the chalk line to “snap” against the footing, applying a line of colored chalk to the cured concrete footing. This process is repeated, as necessary, until the entirety of the perimeter of the concrete footing is marked or chalked, indicating exactly where the foundation walls are to be constructed.

A foundation wall is normally constructed between an interior foundation wall form and an exterior foundation wall form. The interior and exterior foundation wall forms can consist of one or more panels attached together to provide the required length. The interior and exterior foundation wall forms can be united or secured together at regularly spaced intervals by metal ties which maintain the spacing of the interior and exterior foundation wall forms from each other when the foundation wall forms are erected in place on the concrete footing.

The interior and exterior foundation wall forms can be erected separately and be held in place by temporary supports while the metal ties are being inserted and fixed in place. Alternatively, the metal ties can be attached before the interior and exterior foundation wall forms are placed on the concrete footing, whereby the interior and exterior wall forms are placed on the concrete footing as a single pre-assembled unit. Also, it is known to attach ties at the tops of the interior and exterior foundation wall forms to maintain a desired spacing therebetween.

One problem with such conventional foundation wall construction is that the only thing holding the foundation wall forms on the concrete footing is gravity. Accordingly, any substantial lateral force applied at the base of the interior and/or exterior foundation wall forms can move the wall forms laterally relative the concrete footing. On a typical 10 to 40 foot length of wall form, the force of a worker accidentally kicking the wall form adjacent to the concrete footing can move the wall form by one or more inches, sometimes up to 3 to 4 inches. If concrete is then poured between the interior and exterior wall forms with the wall forms being misaligned, the resulting concrete foundation wall will not be straight. In addition, misalignments at the base of the foundation wall can typically be magnified, and in opposing direction, at the top of the foundation wall. The overall result is that the upright wall of the building is formed crooked, typically crooked longitudinally and off-specification with respect to its, typically vertical, upright angle. Such a crooked foundation wall can result in all variety of compromises having to be made in that portion of the building which is supported by the misaligned foundation wall.

A second problem encountered when the chalking system is used to mark the locations for the interior and exterior foundation wall forms is that rain or inclement weather can readily erase the chalk lines. The chalk lines are usually made the day before the interior and exterior foundation wall forms are set into place. If a rain shower occurs in the meantime, it will be necessary for the construction people to again rechalk the positioning lines, thus doubling the work.

Now a bracket assembly and method of using such bracket assemblies has been invented to solve the above-identified problems.

SUMMARY OF THE INVENTION

Briefly, this invention relates to a bracket assembly for facilitating the installation of a concrete wall on a concrete footing. The bracket assembly includes a base member having an upper surface and a lower surface, and first and second upwardly extending flanges. A cavity is formed in the lower surface of the base member. A first aperture is formed through the base member and into the cavity and a sealant is positioned in the cavity. A retainer and shock absorber assembly is secured to the upper surface and an aperture is formed therethrough which is coaxially aligned with the first aperture. A fastener having a shank with a pointed end is inserted through the aperture such that the pointed end is initially encased in the sealant. The fastener is inseparable from the bracket assembly and is capable of being driven into the concrete footing.

In another embodiment, the bracket assembly includes a base member, a first end, a second end, an upper surface, a lower surface, and first and second flanges extending upward from the first and second ends, respectively. The first and second flanges are integrally formed with the base member. The bracket assembly also includes a pair of channels formed in the lower surface of the base member. A pair of first apertures is formed through the base member and each of the pair of first apertures is aligned with one of the pair of channels. A sealant is positioned in each of the pair of channels and extends across the width of the lower surface of the bracket assembly. The bracket assembly further includes a pair of retainer and shock absorber assemblies each secured to the upper surface and each having an aperture formed therethrough which is coaxially aligned with one of the first apertures. A fastener having a shank with a pointed end is inserted through each of the apertures such that the pointed end is initially encased in the sealant. Each of the fasteners is inseparable from the bracket assembly and is capable of being driven into the concrete footing.

This invention also relates to a method of facilitating the installation of a concrete wall on a concrete footing. The method includes the steps of marking a pair of spaced apart lines on an upper surface of a concrete footing. Two or more bracket assemblies are then positioned between the pair of spaced apart lines at predetermined distances. Each of the bracket assemblies includes a base member having an upper surface and a lower surface, and first and second upwardly extending flanges. A cavity is formed in the lower surface of the base member. A first aperture is formed through the base member and into the cavity and a sealant is positioned in the cavity. A retainer and shock absorber assembly is secured to the upper surface and an aperture is formed therethrough which is coaxially aligned with the first aperture. A fastener having a shank with a pointed end is inserted through the aperture such that the pointed end is initially encased in the sealant. The fastener is inseparable from the bracket assembly and is capable of being driven into the concrete footing. As the bracket assembly is secure to the concrete footing, the sealant forms a watertight seal under the bracket and adjacent to the concrete footing. Interior and exterior foundation wall forms are then positioned on either side of the bracket assemblies and concrete is poured therebetween to create a concrete foundation wall.

The general object of this invention is to provide a bracket assembly for facilitating installation of a concrete wall on a concrete footing. A more specific object of this invention is to provide a method of facilitating installation of a concrete wall on a concrete footing.

Another object of this invention is to provide inexpensive bracket assemblies that can be easily and quickly secured to an upper surface of a concrete footing so as to align interior and exterior foundation wall forms into which concrete can be poured to form a concrete foundation wall on top of a concrete footing.

A further object of this invention is to provide bracket assemblies that are permanently secured between a concrete footing and an upstanding concrete foundation wall and which form a watertight seal between a lower surface of the bracket and the upper surface of the concrete footing.

Still another object of this invention is to provide bracket assemblies that are inexpensive to manufacture and are easy to use to ensure that a concrete foundation wall which is to be poured onto a concrete footing is correctly positioned.

Still further, an object of this invention is to provide a unitary bracket assembly that will reduce the time it takes to correctly position interior and exterior wall forms on a concrete footing.

Other objects and advantages of the present invention will become more apparent to those skilled in the art in view of the following description and the accompanying drawings.

The invention is capable of other embodiments or of being practiced or carried out in other various ways. Also, it is to be understood that the terminology and phraseology employed herein is for purpose of description and illustration and should not be regarded as limiting. Like reference numerals are used to indicate like components.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIGS. 1-3, a bracket assembly10is shown for facilitating installation of a concrete wall on a concrete footing. The bracket assembly10includes a base member12having a first end14, a second end16, a first side edge18a second side edge20, an upper surface22and a lower surface24. Each of the upper and lower surfaces,22and24respectively, can be planar and/or smooth in appearance or either can have an irregular appearance. Desirably, the lower surface is planar. The base member12can be formed from almost any material, including but not limited to: aluminum, tin, zinc, plastic, a thermoplastic such as polyethylene or polypropylene, a composite material formed from two or more different materials, an alloy, a metal alloy, or from any other material known to those skilled in the art. Desirably, the base member12is formed from a non-ferrous material or a non-metallic material so that it will not rust. By “nonferrous” it is meant a material that is not composed of or contains iron. By “nonmetallic” it is meant a material that is not metallic or being a nonmetal. More desirably, the base member12will be constructed from a thermoplastic material since it is inexpensive compared to an alloy or composite material. A thermoplastic material can be formed by any known process, including but not limited to: injection molding, extrusion, etc. Even more desirably, the base member12is constructed of a waterproof and rust-proof plastic.

Referring toFIGS. 1 and 2, the bracket assembly10has a length l, a width w and a thickness t. The length l, width w and the thickness t of the bracket assembly10can vary depending upon the material from which it is constructed and the process used to form the bracket assembly10. The length l can be any desired length but normally will correspond to the standard width at which concrete foundation walls are poured so as to meet city, town, county, state and/or federal building codes. For a residential house, the concrete foundation walls are normally 6 or 8 inches in thickness. For commercial buildings, the concrete foundation walls are typically 8, 10 or 12 inches in thickness. However, depending upon the load of the building, the concrete mix and the presence of any reinforcement members or chemicals used in the concrete, the width of the concrete foundation wall can vary from 4 inches up to about 2 feet. Some government installations can actually use concrete foundation walls that are greater than 2 feet in width.

It should also be recognized that new materials, such as sheets of insulation formed from Styrofoam and other materials, are being used in place of the conventional aluminum, steel, metal or wood concrete foundation wall forms. When such insulation sheets are used, they normally stay in place after the concrete cures and therefore the finished width of the concrete foundation wall located between these sheets can result in some odd dimensions. Because of this, the length l of the bracket assembly10may have to be constructed at 8.25 inches, 8.5 inches or 8.75 inches versus the standard 8 inches.

The width w of the bracket assembly10can range from between about 0.25 inches to about 12 inches. Desirably, the width w of the bracket assembly10can range from between about 0.5 inches to about 6 inches. More desirably, the width w of the bracket assembly10can range from between about 0.75 inches to about 3 inches. Even more desirably, the width w of the bracket assembly10can range from between about 1 inch to about 2 inches. A width w for the bracket assembly10of about 1 inch is sufficient for most residential construction of concrete foundation walls.

Referring toFIG. 2, the thickness t of the bracket assembly10can be very dependent upon the process used to form the bracket assembly10, especially when the bracket assembly10is formed from a thermoplastic material, such as polyethylene. The thickness t of the bracket assembly10can range from about 0.05 inches to about 0.5 inches. Desirably, the thickness t of the bracket assembly10will range from about 0.08 inches to about 0.4 inches. More desirably, the thickness t of the bracket assembly10will range from about 0.1 inches to about 0.3 inches. Even more desirably, the thickness t of the bracket assembly10will range from about 0.12 inches to about 0.2 inches. A thickness t for the bracket assembly10of about 0.125 inches is sufficient for most residential construction of concrete foundation walls.

It should be noted that the thickness dimension of the first and second flanges,26and28respectively, can be the same or different from the thickness of the remainder of the base member12. Desirably, the entire base member12will be manufactured to a single thickness t.

Still referring toFIGS. 1 and 2, the bracket assembly10also includes a first flange26and a second flange28. The first and second flanges,26and28respectively, are spaced apart from one another with the first flange26being located adjacent to or abutting the first end14and the second flange28being located adjacent to or abutting the second end16. The first and second flanges,26and28respectively, can be aligned at an angle to the base member12. Desirably, the first and second flanges,26and28respectively, are aligned approximately at a right angle or 90 degrees to the base member12. More desirably, the first and second flanges,26and28respectively, are aligned at a right angle to the base member12. In other words, the first and second flanges,26and28respectively, are aligned perpendicular to the base member12. The first and second flanges,26and28respectively, are integrally formed with the base member12and extend upwardly therefrom. By “integral” it is meant a unitary or complete unit, essential or necessary for completeness. By forming the base member12as an integral unit, one can decrease the cost of manufacturing the base member12since the first and second flanges,26and28respectively, do not have to be adhered, glued, joined, screwed, bolted or somehow mechanically or chemically joined to the base member12.

Referring toFIG. 2, one can clearly see that the bracket assembly10has a C-shaped or U-shaped configuration. However, the bracket assembly10can have any desired configuration. Desirably, the first and second flanges,26and28respectively, will square off the first and second ends,14and16of the base member12and give the bracket assembly10the appearance of half of a rectangle. InFIG. 2, one will also see that each of the first and second flanges,26and28respectively, has a height h. The height h is measured from the upper surface22of the base member12to a free or terminal end30of each of the first and second flanges,26and28respectively. The height h of the first and second flanges,26and28respectively, can vary to suit one's particular needs and requirements. However, it has been found that the height h of the first and second flanges,26and28respectively, should range from between about 0.5 inches to about 3 inches. Desirably, the height h of the first and second flanges,26and28respectively, should be at least about 0.6 inches, and more desirably at least about 0.75 inches. A height h for the first and second flanges,26and28respectively, of between about 0.75 inches to about 2 inches works well for most residential construction of concrete foundation walls.

It should be noted that the first and second flanges,26and28respectively, can be manufactured to the same or different dimensions. Desirably, the height h of each of the first and second flanges,26and28respectively, will be equal.

Another way of calculating a sufficient height h for the first and second flanges,26and28respectively, is to adjust the height h of the first and second flanges,26and28respectively, relative to the length l of the base member12. Typically, the height h of each of the first and second flanges,26and28respectively, should range from between at least about 5% to at least about 50% of the length l of the bracket assembly10. Desirably, the height h of each of the first and second flanges,26and28respectively, should be at least about 7%, more desirably, at least about 8%, and even more desirably, at least about 10% of the length l of the bracket assembly10. By using a height h dimension for the first and second flanges,26and28respectively, within the above ranges, one can be assured that the bracket assembly10will work well for its intended purpose.

Referring now toFIGS. 2 and 3, the bracket assembly10also has at least one cavity32formed in the base member12. The cavity32has an opening34aligned with the lower surface24. The cavity32can be almost any desired geometrical shape or configuration. InFIG. 3, the cavity32is shown as having a round or circular opening similar to what can be produced by a counter bore or a counter sink. By “counter bore or counter sink” it is meant a hole or opening with the exposed part enlarged adjacent to the lower surface24. The opening34can be sized to be smaller than, equal to or be larger than the dimensions of the cavity32. Depending upon the configuration of the cavity32, in some cases the opening34is larger than the dimensions of the cavity32. The opening34typically has a circular profile.

InFIG. 3, the cavity32is shown having a width w1. The width w1should extend across at least about 75% of the width w of the base member12. Desirably, the width w1should extend across at least about 85% of the width w of the base member12. More desirably, the width w1should extend across at least about 95% of the width w of the base member12. Even more desirably, the width w1should extend completely across the width w of the base member12. The reason for this size dimension will be explained shortly.

The cavity32can be formed between the upper surface22and the lower surface24of the base member12. The upper surface22can be formed on a horizontal plane and the cavity32can have an uppermost surface which lies above the horizontal plane of the upper surface22.

Still referring toFIGS. 2 and 3, the bracket assembly10further includes a first aperture36formed through the base member12and which is aligned with the cavity32. The aperture36is shown extending from the upper surface22of the base member12down into the cavity32. Desirably, the aperture36is coaxially aligned with the circular opening34. The length of the aperture36will partly depend upon the thickness t of the bracket assembly10.

A sealant38is positioned in the cavity32. Desirably, some of the sealant38will extend downward a slight amount below the lower surface24of the base member12. More desirably, some of the sealant38will extend across the width w of the base member12. It is important to have the sealant38extend across the width w of the base member12so as to form a moisture and/or watertight seal under the bracket assembly10. The sealant38can initially extend below the lower surface24of the base member12by from between about 0.01 to about 0.25 inches. Since the upper surface of a cured concrete footing can be rather rough or coarse, the extra sealant38present below the lower surface24of the base member12will assure that a good seal is formed when the bracket assembly10is secured to the concrete footing.

The sealant38can be any material that can be used to form a moisture and/or water barrier on the lower surface24of the base member12to prevent moisture and/or water from passing from the outside of the foundation wall to the inside of the foundation wall. The sealant38should be capable of forming a moisture proof, watertight, waterproof or water repellant seal between the lower surface24of the base member12and an upper surface of a concrete footing. Various materials known to those skilled in the art can be used for the sealant38. A number of polymers are readily available that can perform this intended function. One material that works well as the sealant38is silicone. Silicone is any of a group of semi-inorganic polymers of siloxane, characterized by high lubricity and therefore stability, extremely water repellent, and physiological inert. Silicone is a water repellant, pliable material that remains receptive to change in physical dimensions during its useful life. Silicone is commercially available from a number of vendors. The sealant38can also be foam, insulating foam, expandable foam, a polyurethane or any other material known to those skilled in the art which has moisture and/or water resistance and/or water repellant properties.

The sealant38should be pliable so that it can be inserted into the cavity32and can extrude outward from the perimeter of the cavity32a predetermined amount so as to form a moisture and/or watertight seal across the width w of the lower surface24of the base member12. By “pliable” it is meant that the sealant38can be easily shaped, is adaptable, and is receptive to change. As pressure is exerted on the upper surface22of the base member12, the sealant38will form a tight seal against the upper surface of the concrete footing.

It should be noted that the sealant38does not have to set or acquire a final configuration but instead can be fluid such that it can change shape over its useful life. Silicone has this unique characteristic.

Referring now toFIGS. 2,4and5, the bracket assembly10further includes a retainer and shock absorber assembly40. The retainer and shock absorber assembly40has an upper surface42, a lower surface44and an aperture46extending therebetween. The lower surface44is secured to the upper surface22of the base member12, such as by adhesive48or by other securement devices known to those skilled in the art. For example, the lower surface44of the retainer and shock absorber assembly40can be secured or attached to the upper surface22of the base member12by a chemical fastener such as: an adhesive, a glue, an epoxy, a resin, or other compounds known to those skilled in the art, or by a mechanical fastener such as: by welding, by using heat and pressure, or other means known to those skilled in the art. Desirably, the lower surface44of the retainer and shock absorber assembly40is adhered to the upper surface22of the base member12by an adhesive.

The aperture46is coaxially aligned with the first aperture36which is formed in the base member12. Desirably, both the first aperture36and the aperture46are of the same diameter. Alternatively, the diameter of the aperture46can be slightly smaller or larger than the diameter of the first aperture36. For example, the diameter of the aperture46can be slightly smaller than the diameter of the first aperture36. The coaxially alignment of the aperture46with the first aperture36establishes a straight bore which extends completely through both the retainer and shock absorber assembly40and the base member12. The aperture46formed through the retainer and shock absorber assembly40can vary in size and geometrical shape. Desirably, the aperture46has a circular cross-section. The aperture46has an outer periphery50, seeFIG. 5. The size of the outer periphery50can vary but usually is less than about 0.25 inches in diameter. Desirably, the diameter of the aperture46is less than about 0.2 inches. More desirably, the diameter of the aperture46is less than about 0.15 inches. Even more desirably, the diameter of the aperture46is less than about 0.1 inches.

Referring toFIGS. 4 and 5, the retainer and shock absorber assembly40also includes a pair of oppositely aligned fingers52and54secured to and extending inwardly from a base member55. The base member can have any desired geometrical shape. Desirably, the base member55is cylindrical in configuration. Each finger52and54has a first end56which extends within the circumference of the outer periphery50of the aperture46. The first ends56,56are located within the base member55. A void area57is located within the base member55and is present below each of the pair of fingers52and54. The void area57can occupy the entire area of the base member55. The void area57allows the pair of fingers52and54to flex downward.

The pair of fingers52and54are sized and configured to contact and engage a fastener58which is inserted into the aperture46and passes below the pair of fingers52and54. The pair of fingers52and54will prevent the fastener58from being withdrawn from the retainer and shock absorber assembly40. Optionally, the fastener58may be removed from the retainer and shock absorber assembly40only when excessive force is used. When this occurs, the fastener58and/or the retainer and shock absorber assembly40will most likely be destroyed or deformed beyond the point of being useful for their intended purpose.

Referring toFIG. 6, each of the pair of fingers52and54has a second end60which is aligned opposite to the first end56. Each of the pair of fingers52and54also has a first side edge62, a second side edge64, an upper surface66and a lower surface68. The upper surface66has a non-planar configuration between the first and second side edges,62and64respectively. Desirably, this non-planar configuration is concave or in the shape of a hollow disc. When each of the upper surfaces66,66of the pair of fingers52and54is concave, it makes it very difficult for the pair of finger52or54to flex upward. In other words, the pair of oppositely aligned fingers52and54will prevent a fastener58, which is positioned in the aperture46, from being separated from the retainer and shock absorber assembly40because the pair of fingers52and54will engage with the fastener58and hold it firm.

It should be noted that the pair of fingers52and54will not prevent the fastener58from being hammered or driven downwardly into a concrete footing but will prevent the fastener58from being separated from the retainer and shock absorber assembly40.

The first end56of each of the pair of fingers52and54also has a plurality of teeth70formed thereon. The teeth70can vary in number, size and/or configuration. Each of the plurality of teeth70can be sharp and terminate in a point. The oriented of the teeth70can be adjusted inward and/or downward as to increase their gripping power as they engage with a fastener58passing through the aperture46. Alternatively, the plurality of teeth70can extend horizontally inward toward the center of the aperture46. The plurality of teeth70help ensure that a fastener58inserted in the aperture46cannot be withdrawn therefrom.

Referring again toFIG. 4, the retainer and shock absorber assembly40further includes a shock absorber72. The shock absorber72can be formed from various materials. Desirably, the shock absorber72is formed from a compressible material. The shock absorber72can be constructed of almost any flexible, malleable, ductile, plastic, pliable, pliant, supple and/or adaptable material which has the ability to readily undergo change or modification without breaking. One material that works well as the shock absorber72is rubber. Rubber is an amorphous, elastic, solid polymer of isoprene. Rubber is generally prepared by coagulation and drying of the milky sap or latex of various tropical plants, especially the rubber tree, and subsequently vulcanized, pigmented, and otherwise modified. However, other numerous synthetic elastic materials, synthetic rubber, polymers, etc. of varying chemical composition, with properties similar to those of natural rubber, can also be used. The shock absorber72is shown as being positioned above or adjacent to the pair of fingers52and54. However, the shock absorber72can be positioned above, below, within or so as surround the pair of fingers52and54. In addition, the pair of fingers52and54can be partially or be completely enclosed by the shock absorber72.

The aperture46extends through the shock absorber72as well as between the first ends56,56of each of the pair of fingers52and54. The aperture46is sized and configured to permit a portion of the fastener58to pass therethrough. A slight interference fit between the shock absorber72and the fastener58is beneficial in keeping the fastener58attached to the retainer and shock absorber assembly40. Desirably, the outer periphery50of the aperture46is smaller than that portion of the fastener58which is designed to be inserted therein. The shock absorber72can also be constructed such that it only partially surrounds a portion of the fastener58. InFIG. 4, the shock absorber72is depicted as a disc or thick washer situated above the pair of fingers52and54. The shock absorber72can also be formed in a variety of other geometrical shapes.

Referring again toFIGS. 1,2and4, the fastener58is sized and configured to be positioned in and at least partially pass through the aperture46. The fastener58can be almost any kind of mechanical device known to those skilled in the art. For example, the fastener58can be a nail, a nail having a plurality of slits, grooves, or threads to facilitate its ability to enter into cured concrete, a screw, a bolt, a rivet, a stud, etc.

As best illustrated inFIG. 4, the fastener58includes a shank74having a pointed end76and an opposite end78containing an enlarged head80. The shank74extends through the aperture46formed in the retainer and shock absorber assembly40and into the first aperture36. The pointed end76of the shank74is initially encased in the sealant38. This is the position of the fastener58as the bracket assembly10is placed on the concrete footing. When the pointed end76of the shank74is embedded in the sealant38, one does not have to worry that the pointed end76can scratch or cut the skin of a construction worker. It is a safety feature to initially embed the pointed end76in the sealant38. Alternatively, one could insert the fastener58after the bracket assembly10has been positioned on the concrete footing. Once the fastener58is driven down into the aperture46beyond the position of the pair of oppositely aligned fingers52and54, the fastener58will be unable to be withdrawn.

Desirably, the diameter of the aperture46is smaller in dimension than the diameter of the shank74. Likewise, the outer periphery of the aperture46can be smaller than the outer periphery of the shank74. Typically, the shank74will have a cylindrical shape with a circular cross-section. The diameter of the shank74will be larger than the diameter of the aperture46to create an interference fit. This interference fit will assure that the fastener58is aligned perpendicular to the concrete footing into which it will be hammered or driven, such as by a nail gun. The interference fit will also assist in retaining the fastener58to the bracket assembly10.

The enlarged head80on the fastener58allows a construction worker to strike the fastener58with a hammer or with a power gun and drive or move the fastener58down through the sealant38and completely through the first aperture36and into a concrete footing. However, fasteners58without enlarged heads80can also be utilized. As the fastener58passes through the sealant38, it will displace some of the sealant38and force it to extend downward and/or outward across a major portion of the width w of the base member12. Ideally, the sealant38will be spread across the entire width w of the base member12. This action, along with the excess sealant38that is present below the lower surface24of the base member12, will create a moisture proof, watertight, waterproof or water repellant seal between the lower surface24of the base member12and the upper surface of the concrete footing. By “moisture proof” it is meant that the bracket assembly10is secured to the concrete footing such that moisture cannot enter or escape under the lower surface24of the base member12. By “watertight” it is meant that the bracket assembly10is secured to the concrete footing such that water cannot enter or escape under the lower surface24of the base member12. By “waterproof” it is meant that the bracket assembly10is secured to the concrete footing such that water cannot penetrate under the lower surface24of the base member12.

The sealant38is made of or treated with rubber, plastic, a polymer or a sealing agent to resist water penetration, or to be water repellant. By “water repellant” it is meant that the bracket assembly10is secured to the concrete footing such that it is resistant to water but not entirely waterproof. The fastener58will also permanently secure the bracket assembly10to the concrete footing. The bracket assembly10is not designed to be removed once it is attached to the concrete footing unless it is incorrectly positioned.

Optionally, the adhesive48can be positioned between a lower surface of the shock absorber72and the upper surface22of the base member12to hold the shock absorber72secure to the bracket assembly10. When the adhesive48is present, one can feel secure in the fact that the fastener58will be joined to the bracket assembly10. This will ensure that the fastener58is not separated from the bracket assembly10. One of the clear benefits of the bracket assembly10is that it is a unitary device that does not require additional elements or items to be attached or to be joined to it. At the construction site, the construction worker simply has to place or position the bracket assembly10onto the upper surface of the cured concrete footing and secure it in its proper alignment by hammering or driving the fastener58into the concrete footing. Each of the bracket assemblies10will remain in place and it is not necessary to remove any of the bracket assemblies10after the concrete foundation wall is poured and cured.

The shock absorber72functions to permit the fastener58, i.e. a nail, screw, etc. to be driven through both the first aperture36and the sealant38and into the concrete footing by a hammer, nail gun, etc. to secure the bracket assembly10thereto. As the fastener58is driven down into the concrete footing, the enlarged head80on the fastener58will contact the shock absorber72. The shock absorber72can flex and contract while providing resistant which prevents the fastener58from being driven further downward by an appreciable amount. In short, the shock absorber72will prevent the base member12from breaking or cracking as the fastener58is inserted into the concrete footing. As the fastener58passes through the sealant38, it will displace some of the sealant38and cause it to move downward and/or outward. This helps assure that a good water tight seal is created between the lower surface24of the base member12and the upper surface of the cured concrete footing.

Referring now toFIG. 7, an alternative embodiment for the retainer and shock absorber assembly40′ is shown. In this embodiment, the retainer and shock absorber assembly40′ has a pair of inwardly extending fingers52′ and54′ each having a first end56and a second end82. The first ends56,56are sized and configured to engage with the shank74of a fastener58as was described above in reference toFIGS. 1-3. The second ends82,82are secured to the cylindrical base member55′, for example to an interior surface of the cylindrical base member55′. The cylindrical base member55′ has an outer periphery84which is completely surrounded by the shock absorber72′. In other words, the shock absorber72′ portion of the retainer and shock absorber assembly40′ surrounds 360 degrees of the cylindrical base member55′, as well as the upper portion of the cylindrical base member55′. This is different fromFIG. 4, wherein the shock absorber72was only positioned above the pair of fingers52and54. LikeFIG. 4, a void area57′ is located within the cylindrical base member55′ and is present below each of the pair of fingers52′ and54′. Desirably, the entire area within the periphery of the cylindrical base member55′ and below the plane of the pair of fingers52′ and54′ is void of shock absorber material. This void area57′ allows the pair of fingers52′ and54′ to flex downward.

Referring now toFIGS. 8-10, another embodiment of a bracket assembly10′ is shown for facilitating the installation of a concrete wall on a concrete footing. The bracket assembly10′ includes a base member12′ having a first end14′, a second end16′, a first side edge18′, a second side edge20′, an upper surface22′ and a lower surface24′. Desirably, the lower surface24′ is planar. The bracket assembly10′ has a length I′, a width w′ and a thickness t′. The length I′, the width w′ and the thickness t′ can vary in dimension depending upon the material from which it is constructed and the process used to form the bracket assembly10′. The bracket assembly10′ also includes a first flange26′ and a second flange28′. The first and second flanges,26′ and28′ respectively, are spaced apart from one another with the first flange26′ being located adjacent to or abutting the first end14′ and the second flange28′ being located adjacent to or abutting the second end16′. The first and second flanges,26′ and28′ respectively, are aligned approximately at a right angle or 90 degrees to the base member12′. In other words, the first and second flanges,26′ and28′ respectively, are aligned approximately perpendicular to the base member12′. Desirably, the first and second flanges,26′ and28′ respectively, are integrally formed with the base member12′ and extend upwardly therefrom. By forming the bracket assembly10′ as an integral unit, one can decrease the cost of manufacturing the bracket assembly10′ since the first and second flanges,26′ and28′ respectively, do not have to be adhered, glued, joined, screwed, bolted or somehow mechanically or chemically joined to the base member12′.

Referring toFIG. 9, one can clearly see that the bracket assembly10′ has a C-shaped or U-shaped configuration. However, other configurations can also be utilized. Desirably, the first and second flanges,26′ and28′ respectively, will square off the first and second ends,14′ and16′ of the base member12′ and give the bracket assembly10′ the appearance of half of a rectangle. InFIG. 9, one will also see that each of the first and second flanges,26′ and28′ respectively, has a height h′. The height h′ is measured from the upper surface22′ of the base member12′, adjacent each flange26′ or28′, to a free or terminal end30′,30′. The height h′ of the first and second flanges,26′ and28′ respectively, can vary to suit one's particular needs and requirements. However, it has been found that the height h′ of the first and second flanges,26′ and28′ respectively, should range from between about 0.5 inches to about 3 inches. Desirably, the height h′ of the first and second flanges,26′ and28′ respectively, should range from between about 0.6 inches to about 2.5 inches. More desirably, the height h′ of the first and second flanges,26′ and28′ respectively, should range from between 0.7 inches to about 2.25 inches. Even more desirably, a height h′ for the first and second flanges,26′ and28′ respectively, of between about 0.75 inches to about 2 inches works well for most residential construction of concrete foundation walls.

Referring now toFIGS. 9 and 10, the bracket assembly10′ differs from the embodiment shown inFIGS. 1-3, in that it has a pair of cavities32′,32′ formed in the base member12′. The pair of cavities32′,32′ is spaced apart from one another. Each of the pair of cavities32′,32′ is formed or configured as a channel86having a central axis z—z, seeFIG. 10. Each of the channels86,86can be a long, narrow cavity of various cross-sectional configurations. InFIG. 9, each of the channels86,86has a trapezoidal configuration. By “trapezoidal” it is meant a quadrilateral having two parallel sides. However, it is to be understood that each of the channels86,86can have any desired cross-sectional configuration including, but not limited to: square, rectangular, triangular, circular, round, oval, elliptical, or any other geometrical shape known to those skilled in the art. Each of the channels86,86has a first end88and a second end90. Each of the channels86,86spans or bridges across the entire width w′ of the bracket assembly10′ such that the first end88is located on one side of the base member12′ and the second end90is located on the opposite side of the base member12′. The central axis z—z of each of the channels86,86is aligned approximately parallel or 180 degrees to the first and second flanges,26′ and28′ respectively. Desirably, each of the channels86,86is aligned parallel to the first and second flanges,26′ and28′ respectively.

Each of the pair of channels86,86is located adjacent to and inward of one of the first and second flanges,26′ and28′ respectively. The central axis z—z of each of the channels86,86should be spaced at least about 0.5 inches away from the adjacent flange26′ or28′. This clearance is needed to provide sufficient room for a construction worker to drive a fastener58down through the respective channels86,86when the bracket assembly10′ is being secured to an upper surface of a concrete footing. It is also desirable to have at least 3 inches of clearance, measured along the length I′ of the bracket assembly10′, between each of the channels86,86. Furthermore, each of the pair of channels86,86has an opening34′ aligned with the lower surface24′ of the base member12′. InFIG. 9, each of the openings34′,34′ is narrower than the remainder of the respective channel86. This is another difference from the embodiment shown inFIGS. 1-3. Desirably, each of the openings34′ have a minimum dimension, measured parallel to the length I′ of the bracket assembly10′, of at least 0.1 inches, and more desirably, of at least 0.2 inches. This size dimension will help ensure that the sealant38, positioned in the channels86,86can form an effective seal beneath the lower surface24′ of the bracket assembly10′ and an upper surface of the concrete footing.

Still referring toFIGS. 9 and 10, the bracket assembly10′ further includes a pair of apertures36′,36′ each aligned with one of the channels86,86. Each of the pair of apertures36′,36′ extends from the upper surface22′ of the base member12′ down into the cavities32′,32′. Desirably, each of the apertures36′,36′ is equally spaced across the width w′ of the bracket assembly10′ between the first and second ends,88and90respectively, of each of the channels86,86. The length of each of the apertures36′,36′ will partly depend upon the thickness of the base member12′.

A sealant38′, as described above, is position in each of the pair of channels86,86. Desirably, some of the sealant38′ will extend downward a slight amount below the lower surface24′ of the base member12′. Each of the channels86,86extends completely across the width w′ of the bracket assembly10′, and therefore the sealant38′ will also extend completely across the width w′ of the bracket assembly10′. The sealant38′ can initially extend below the lower surface24′ of the base member12′ by from between about 0.01 to about 0.25 inches. Since the upper surface of a cured concrete footing can be rather rough or coarse, the extra sealant38′ present below the lower surface24′ of the bracket assembly10′ will assure that a good seal is formed when the bracket assembly10′ is secured to the concrete footing.

Referring again toFIGS. 8 and 9, the bracket assembly10′ further includes a pair of fasteners58,58each sized and configured to be positioned in and at least partially pass through one of the apertures46,46and initially have its pointed end76embedded in the sealant38′. Each of the pair of fasteners58,58can be constructed as described above with reference to the embodiment shown inFIGS. 1-3. Each of the pair of fasteners58, as shown inFIG. 9, has a shank74with a pointed end76and an opposite end78. Each of the pair of fasteners58,58has an enlarged head80at its upper or opposite end78. Each of the pair of fasteners58,58can be movably retained in one of the apertures46,46such that the respective fastener58can only be driven or hammered downwardly into the bracket assembly10′. The shank74of each of the pair of fasteners58,58can form an interference fit with the aperture46. A retainer and shock absorber assembly40or40′ is also present. Each retainer and shock absorber assembly40or40′ is secured to the upper surface22of the base member12′ by an adhesive48. A sealant38′ is positioned in each of the pair of channels86,86and serves the same purpose as described above with reference toFIGS. 1-3.

The diameter or cross-section of each of the first apertures36′,36′ can be slightly less than the diameter or cross-section of the shank74of each of the pair of fasteners58,58. This size difference can create an interference fit between each fastener58and corresponding aperture46. The interference fit helps hold each of the fasteners58,58in the pair of first apertures36′,36′. However, an interference fit is not required. When an interference fit is present, it will not prevent the pair of fasteners58,58from being driven or hammered down through one of the first apertures36′,36′. The enlarged head80allows a construction worker to strike each of the pair of fasteners58,58with a hammer or power gun and drive or move it down through the respective first aperture36′, through the sealant38′ and into a concrete footing. As each of the fasteners58,58passes through the sealant38′, it will displace some of the sealant38′. This action, along with the excess sealant38′ that is present, will create a moisture proof, watertight, waterproof or water repellant seal between the lower surface24′ of the bracket assembly10′ and the upper surface of the concrete footing. The pair of fasteners58,58will also permanently secure the bracket assembly10′ to the concrete footing. The bracket assembly10′ is not designed to be removed once it is attached to the concrete footing unless it is incorrectly positioned.

Still referring toFIGS. 9 and 10, the bracket assembly10′ is also depicted as having a pair of retainers and shock absorber assemblies40,40. Each of the pair of retainers and shock absorber assemblies40,40can be formed as described above. Each of the pair of retainers and shock absorber assemblies40,40is shown having an aperture46,46sized to permit a portion of one of the fasteners58,58to pass therethrough. A slight interference fit between each of the fasteners58,58and the apertures46,46is beneficial in keeping each of the retainers and shock absorber assemblies40,40attached to its respective fastener58,58. Each of the retainers and shock absorber assemblies40,40can also be constructed such that it only partially surrounds a portion of one of the fasteners58,58. InFIG. 9, each of the retainers and shock absorber assemblies40,40is depicted as a member situated above and secured to an upwardly extending bulge92formed in the upper surface22′ of the base member12′. As explained above, each of the retainers and shock absorber assemblies40,40can also be formed in a variety of other geometrical shapes, if desired.

Optionally, an adhesive48can be positioned between a lower surface44of each of the retainers and shock absorber assemblies40,40and the upper surface22′ of the base member12′ to hold each of the retainer and shock absorber assemblies40,40′ secure to the bracket12′. When the adhesive48is present along with an interference fit between each of the pair of fasteners58,58and its respective first apertures46,46, one can feel secure in the fact that each of the pair of fasteners58,58will be joined to the bracket assembly10′. This will ensure that each of the pair of fasteners58,58is not separated from the bracket assembly10′. One of the clear benefits of the bracket assembly10′ is that it is a unitary device that does not require additional elements or items to be attached or to be joined to it. At the construction site, the construction worker simply has to place or position the bracket assembly10′ onto the upper surface of the cured concrete footing and secure it in its proper alignment by hammering or driving each of the fasteners58,58into the concrete footing. Each of the bracket assemblies10′ will remain in place and it is not necessary to remove any of the bracket assemblies10′ after the concrete foundation wall is poured and allowed to cure.

The pair of retainers and shock absorber assemblies40,40functions to permit the pair of fasteners58,58, i.e. nails, screws, etc. to be driven through both of the respective first aperture36′,36′ and the respective sealant38′ and into the concrete footing by a hammer, nail gun, etc. to secure the bracket assembly10′ thereto. As each of the pair of fasteners58,58is driven down into the concrete footing, the enlarged head80on each of the fasteners58will contact the respective retainer and shock absorber assemblies40,40. Each retainer and shock absorber assembly40can flex and contract while providing resistant which prevents the respective fastener58from being driven further downward by an appreciable amount. In short, each of the retainers and shock absorber assemblies40,40will prevent the base member12′ from breaking or cracking as the respective fasteners58,58are inserted into the concrete footing. As each of the pair of fasteners58,58passes through the respective sealant38′, it will displace some of the sealant38′ and cause it to move downward and outward. This helps assure that a good moisture tight and/or water tight seal is created between the lower surface24′ of the bracket assembly10′ and the upper surface of the cured concrete footing.

Referring now toFIGS. 11-13, an alternative retainer and shock absorber assembly40″ is shown secured to the bracket assembly10′, depicted inFIG. 9. The retainer and shock absorber assembly40″ includes a hollow sleeve71having an interior surface73. The size and shape of the hollow sleeve71and the interior surface73can vary. Desirably, the hollow sleeve71has a cylindrical exterior shape and the interior surface73is circular or round in cross-section. The retainer and shock absorber assembly40″ is designed to be positioned adjacent to the lower surface24′ of the bracket assembly10′ with the hollow sleeve71extending upward through the first aperture36′ and into the aperture46′.

A plurality of fingers75are formed integral with or are secured to the interior surface73of the hollow sleeve71. Each of the plurality of fingers75can be spaced at an equal distance apart from one another around the inner periphery of the interior surface73or they can be randomly arranged. The plurality of fingers75can be arranged in two or more vertically spaced apart circles or rings within the interior surface73. The plurality of fingers75can also be aligned with one another or be offset from one another in either the horizontal or vertical planes. Likewise, the plurality of fingers75can be arranged in various geometrical patterns, including but not limited to: a spiral configuration, a circular configuration, a stepped configuration, a staggered configuration, a random configuration, a regular configuration, a configuration including multiple rows or circles of fingers75, etc.

Secured to one end of the hollow sleeve71is a flange77. The flange77can vary in geometrical size and shape but desirably has a round or square cross-sectional configuration. The width of the flange77can be equal to or be greater than about 1.25 times the width or diameter of the hollow sleeve71. Desirably, the width of the flange77is at least about 1.5 times the width of the hollow sleeve71. More desirably, the width of the flange77is at least two times the width of the hollow sleeve71. It is the flange77that will contact the lower surface24′ of the bracket assembly10′ when the retainer and shock absorber assembly40″ is secured to the bracket assembly10′. The flange77secures the retainer and shock absorber assembly40″ to the bracket assembly10′.

The hollow sleeve71is designed to be inserted through the first aperture36′, formed in the base member12′, and extend into the aperture46′ which is formed in the retainer and shock absorber assembly40″. The hollow sleeve71can form a loose fit, a snug fit or an interference fit with either of the first aperture36′ and/or with the aperture46′. Desirably, the hollow sleeve71will form a snug fit with both of the apertures36′ and46′.

Referring now toFIGS. 12 and 13, the plurality of fingers75is arranged to point or tilt downward toward the flange77and inward toward the center of the interior surface73when the hollow sleeve71is positioned in the apertures36′ and46′. The actual number of fingers75can vary. There can be an odd number of fingers75or an even number of fingers75. Desirably, the number of fingers75will equal or exceed eight. For example, eight fingers can be arranged in a circle, with each spaced 40° apart from one another, seeFIG. 13. More desirably, the number of fingers75will equal or exceed 16. Even more desirably, the number of fingers75will equal or exceed 24. The size and shape of the plurality of fingers75can vary. Each of the plurality of fingers75can be of the same size as the remaining fingers75or at least one of the fingers75can vary in size from another finger75. Typically, all of the fingers75are of the same size. Likewise, each of the plurality of fingers75can be of the same shape as the remaining fingers75or at least one of the fingers75can vary in shape from another finger75. Typically, all of the fingers75are of the same shape.

Referring again toFIG. 12, one can see that the plurality of fingers75are arranged as five vertical, spaced apart rings79. The actual number of rings79can vary from one ring79to ten or more rings79. Each ring79is spaced apart from an adjacent ring79by a predetermined distance. The exact distance between adjacent rings79can be the same or can vary. Usually, the rings79are spaced apart by at least about 0.1 inches. The fastener58is sized and designed to pass down through the interior surface73of the hollow sleeve71and physically contact the plurality of fingers75. The plurality of fingers75will prevent the fastener58from being withdrawn from the retainer and shock absorber assembly40″. However, the plurality of fingers75will allow the fastener58to be hammered or driven downward pass the plurality of fingers75and through the sealant38′ into the concrete footing94.

The retainer and shock absorber assembly40″ also includes a shock absorber81formed from a compressible material. The shock absorber81can be positioned around at least a portion of the hollow sleeve71. Desirably, the shock absorber81will surround that portion of the hollow sleeve71that extends above the upper surface22′ of the bracket assembly10′. The shock absorber81serves the same function as the shock absorber72explained above.

Referring now toFIG. 14, a plan view of a rectangular shaped concrete footing94is shown having an upper surface96. The concrete footing94is at least partially cured or hardened so that it can support weight, such as a foundation wall. Secured to the upper surface96of the concrete footing94is a plurality of the bracket assemblies10or10′. The bracket assemblies10or10′ are spaced a predetermined distance apart over the perimeter of the concrete footing94. Normally, a bracket assembly10or10′ can be placed about 1.5 feet, 2 feet, 3 feet or any desired distance from an adjacent bracket assembly10or10′. At the corners of the concrete footing94or at a bend, at a curved portion, at a shoulder, etc., the bracket assemblies10or10′ can be spaced closer together to provide additional support. For example, at each corner of the concrete footing94, the adjacent bracket assemblies10or10′ may be spaced only a few inches apart.

Still referring toFIG. 14, an interior foundation wall form98and an exterior foundation wall form100are shown being positioned on the upper surface96of the concrete footing94adjacent to the upstanding first and second flanges26and28or26′ and28′ of each bracket assemblies10or10′. The interior and exterior foundation wall forms,98and100respectively, abut against the outside surfaces of the flanges26and28or26′ and28′ and are aligned parallel to one another. The bracket assemblies10or10′ keep and retain the interior and exterior foundation wall forms,98and100respectively, in a parallel alignment and at a set distance apart. The bracket assemblies10or10′ prevent the interior and exterior foundation wall forms,98and100respectively, from becoming misaligned, as indicated by the dotted lines in the upper portion ofFIG. 14.

The interior foundation wall form98has a smooth inner surface102and the exterior foundation wall form100has a smooth inner surface104. The two smooth inner surfaces,102and104, face one another when the interior and exterior foundation wall forms,98and100respectively, are correctly positioned on the upper surface96of the concrete footing94. The interior and exterior foundation wall forms,98and100respectively, are commonly constructed of aluminum, steel, metal, wood or a combination of two or more different materials. The interior and exterior foundation wall forms,98and100respectively, can be obtained in a variety of sizes, such as: 1 foot by 8 feet, 2 feet by 8 feet, 4 feet by 8 feet, etc. or in smaller sizes such as 1 foot by 2 feet, 2 feet by 4 feet, 4 feet by 4 feet, etc. The interior and exterior foundation wall forms,98and100respectively, can also be obtained in various shapes to extend around corners, to form an arc, a semi-circle, a rounded or circular shape, or to form some other geometrical profile. For example, the interior and exterior foundation wall forms,98and100respectively, can be L-shaped, C-shaped, U-shaped, etc.

Turning now toFIGS. 15 and 16, one can clearly see that the interior and exterior foundation wall forms,98and100respectively, are not secured, joined or attached to the first and second flanges26′ and28′ but instead abut such flanges26′ and28′. When properly assembled, the bracket assemblies10or10′ are positioned between the inner surfaces102and104of the interior and exterior foundation wall forms,98and100respectively. The bracket assemblies10or10′ are permanently attached or secure to the concrete footing94by the fasteners58,58and are designed to stay in place after the foundation wall is poured. The bracket assemblies10or10′ prevent the interior and exterior foundation wall forms,98and100respectively, from moving laterally with respect to the concrete footing94. Concrete is then poured between the smooth inner surfaces98and100of the interior and exterior foundation wall forms,98and100respectively. The concrete is allowed to cure or set over a number of days to form a concrete foundation wall106. The curing time is dependent on: the composition of the concrete mix, the length, width and depth of the concrete, the outside temperature, the relative humidity, the climate, and any chemicals added to the concrete mix, as well as other factors known to those skilled in the art.

Once the concrete foundation wall106has at least temporarily cured, the interior and exterior foundation wall forms,98and100respectively, are removed. The interior and exterior foundation wall forms,98and100respectively can be reused multiple times on various buildings. With the bracket assemblies10or10′ in place between the upper surface96of the concrete footing94and a lower surface of the foundation wall106, a seal will be formed by the sealant38. The sealant38will prevent moisture and/or water from flowing along the lower surface,24or24′, of the bracket assembly,10or10′ respectively, from outside of the foundation wall106to the inside of the foundation wall106.

Method

Referring now toFIG. 17, a flow chat is depicted of a method for facilitating the installation of a concrete wall on a concrete footing. The method includes the steps of marking a pair of spaced apart, parallel lines on the upper surface96of a concrete footing94. The set of parallel lines can be formed by using a string encased in a powered, colored chalk. The string can be stretched to a taut position directly above and in close proximity to the upper surface96of the concrete footing94. The string is then pulled upward and released so that it will snap against the upper surface96. This action causes the powered, colored chalk to exit the string and form a line on the concrete footing94. One or two chalked positioning lines can be formed on the upper surface96of the concrete footing94. When one positioning line is used, it should be the exterior positioning line. After the one positioning line is marked, one or more bracket assemblies10or10′ can be aligned perpendicular to the positioning line and be secured in place by the fastener(s)58,58. Optionally, both an interior positioning line and an exterior positioning line are marked on the upper surface96of the concrete footing94. After the two parallel positioning lines are marked, one or more bracket assemblies10or10′ are secured to the upper surface96of the cured concrete footing94by driving the fastener(s)58,58into the concrete footing94, such as by the use of a hammer or a nail gun. Desirably, multiple bracket assemblies10or10′ are used for a single building.

Each of the bracket assemblies10or10′ are positioned between the pair of spaced apart lines at a predetermined distance from one another. The distance between each bracket assembly10or10′ can vary, especially when one has to contend with corners, bends, jogs, etc. Each of the bracket assemblies10or10′ includes a base member12or12′ having a first end14or14′, a second end16or16′, a first side edge18or18′, a second side edge20or20′, an upper surface22or22′ and a lower surface24or24′. Each bracket assembly10or10′ also includes first and second spaced apart flanges,26and28or26′ and28′ respectively, which are integrally formed with the base member12or12′. The first and second flanges,26and28or26′ and28′ respectively, extend upwardly from the base member12or12′. One or more cavities32or32′ are also formed in the base member12or12′. Each of the cavities32or32′ has an opening,34or34′ respectively, aligned with the lower surface24or24′ of the base member12or12′. One or more first apertures36are formed through the base member12or12′ and each of the first apertures36,36is aligned with one of the cavities32or32′. A sealant38is positioned in each of the cavities32or32′ and the sealant38partially extends outward below the lower surface24or24′ of the bracket assembly10or10′. Desirably, the sealant38extends across the entire width w or w′ of the bracket assembly10or10′ in order to form a satisfactory seal. A movable fastener58is positioned in each of the first apertures36.

A retainer and shock absorber assembly40,40′ or40″ is secured or positioned adjacent to the upper surface22,22′ or to the lower surfaces24,24′ of the base member12or12′. An aperture46is formed through the retainer and shock absorber assembly40,40′ or40″. The aperture46is coaxially aligned with the first aperture36. A fastener58which includes a shank74having a pointed end76and an opposite end78is positioned in the aperture46. The opposite or upper end78of the fastener58has an enlarged head80which prevents this end of the fastener58from being driven below the upper surface66of the retainer and shock absorber assembly40,40′ or40″. The shank74extends through the aperture46which is formed in the retainer and shock absorber assembly40,40′ or40″ and into the first aperture36. The pointed end76of the shank74can be initially encased in the sealant38, if desired. The fastener58is inseparable from the retainer and shock absorber assembly40,40′ or40″ by the pair of fingers52and54, or by the plurality of fingers75, which engage the shank74and prevent it from being withdrawn from the retainer and shock absorber assembly40,40′ or40″. The pair of fingers52and54or the plurality of fingers75will allow the fastener58to be driven or hammered downwardly into the concrete footing94but prevent the fastener58from being pulled upwardly so as to be withdrawn from the retainer and shock absorber assembly40,40′ or40″.

Each of the bracket assemblies10or10′ is then secured to the upper surface96of the concrete footing58by driving the fastener(s)58,58through the sealant38and into the concrete footing94. An interior foundation wall form98is then positioned adjacent to and outside of the first flange26or26′. An exterior foundation wall form100is simultaneously or sequentially positioned adjacent to and outside of the second flange28or28′. Each of the interior and exterior foundation wall forms,98and100respectively, has a smooth inner surface,102and104respectively. The interior and exterior foundation wall forms,98and100respectively, are spaced an even distance apart and are aligned parallel to one another. Additional brackets or mechanical devices can be attached to the lower, middle and/or upper surfaces of the interior and exterior foundation wall forms,98and100respectively, to maintain the proper spacing therebetween. Commonly, a mechanical device, such as a tie, is positioned about one foot from the bottom of a foundation wall form, a second mechanical device is positioned about one foot from the top of the foundation wall form, and additional mechanical devices are spaced about every two feet therebetween. Concrete is then poured between the interior and exterior foundation wall forms,98and100respectively, and the concrete is allowed to cure or set to form an upstanding foundation wall106.

Once the concrete has cured or set, the interior and exterior foundation wall forms,98and100respectively, are removed. The bracket assemblies10or10′ are left in place between the upper surface96of the concrete footing94and a lower surface of the foundation wall106. The sealant38, located on the lower surface24or24′ of the brackets assemblies10or10′, can be of a moisture and/or water repellant silicone. The silicone functions to prevent moisture and/or water from seeping under the bracket12or12′ between the concrete foundation wall106and the upper surface96of the concrete footing94. It is important to prevent moisture and/or water from seeping from the outside of the foundation wall106to the inside of the foundation wall106.
