CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority of the U.S. Provisional Application No. 60/829,615 filed on Oct. 16, 2006, in the United States Patent and Trademark Office, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present general inventive concept relates to an anchor system and method for use, for example, in concrete construction, and more particularly, to an anchor system and method which includes a body having a front plate, a top plate, and a back plate and a strap inserted in body such that the body may be fixed in or to concrete or other hard building material with the strap protruding so the strap may be fixed to construction material, for example the framework of a building, steel beam, or roadway.

2. Description of the Related Art

There are several known approaches for anchoring systems for use in the construction industry. Anchor systems are used, for example, to attach two or more concrete slabs together or to attach a concrete slab to another structure. Anchoring systems can be pre or post-installed. The anchor system is either encased in concrete when the pre-fabricated wall is poured or is attached, usually by bolting, to the concrete or other material. One common anchoring systems is for the anchor to be bolted to the building structure and then a steel beam or some framework is secured, through bolting system or soldering, to the anchor.

As structures get larger and more complex, the anchoring systems need to be more versatile allowing for variety of positioning within the building structure. Also, increasing the safety and strength capacity of anchoring systems desired. The amount of load that can be attached to the anchor system is relevant. It is therefore advantageous to have an anchoring system that has increased strength potential. An anchoring system that can be used in a variety of situations for a variety of different loads is advantageous.

SUMMARY OF THE INVENTION

The present general inventive concept relates to an adjustable anchor system and method for use in concrete construction. The present general inventive concept comprises a body with a front plate, a top plate, and a rear plate and a strap with a notch at the head for insertion in an elliptical bore in the top plate The front plate, top plate, and rear plate are all generally rectangular in shape. The front and rear plates each have at least one leg extending from the main body of the plate and at least one member extending generally perpendicular to the plate at approximately ninety degrees. The top plate has a raised lip that is reinforced and where the angled edge of the strap fits. The body can be encased in concrete, such as a wall for a building. A strap may be inserted in the elliptical bore of the body and is fixed, by welding, soldering, or bonding, to the building framework, either a steal beam or metal plate within another piece of concrete. In the bend of the at least one member, there is a punch out. The punch out serves as another means to secure the anchor system to the building material and increases the strength and the amount the anchor system can hold. The body can be made of low corrosion metal or is coated in a J-finish or other such non-corrosive finish.

The modular design concept offers improved pullout capacity of the basic anchor system. Higher capacities are achieved by the addition of component parts, for example studs in the members of the body. The present general inventive concept may be prefabricated and manufactured using an automated process that offers consistent performance levels and reliability. Because the anchor system is prefabricated and the strap is adjustable, the cost of manufacturing the anchor system is greatly reduced. The anchor system can be adjusted to fit the needs of different building structures. The anchor system is an easy, safe, accurate and economical method to locate and connect pre-cast panels to framework while decreasing building costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As required, one or more detailed embodiments of the present general inventive concept are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the principles of the general inventive concept, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present general inventive concept in virtually any appropriately detailed structure.

One embodiment of the present general inventive concept comprises a body 12, illustrated in FIGS. 1-4, and a strap 50, illustrated in FIGS. 5-6, that coordinate as an anchor system 10, illustrated in FIGS. 7-9. FIGS. 1-4 illustrate one embodiment of the present general inventive concept comprising body 12 with a front plate 20, a top plate 40, and a rear plate 30. In one preferred embodiment the plates are generally square or rectangular in shape. Front plate 20 and rear plate 30 are parallel to each other and perpendicular to top plate 40. Front plate 20 has at least one leg 21a extending from the main body of front plate 20 in a direction away from top plate 40. Leg 21a has a bore 22a in the approximate center of leg 21a. Front plate 20 has at least one member 23a extending perpendicular to front plate 20 at approximately ninety degrees and being parallel to top plate 40. Member 23a has a bore 24a in the approximate center of member 23a. A reinforced punch 25a is located in a bend 26a of the angle where member 23a extends. Rear plate 30 has at least one leg 31a extending from the main body of rear plate 30 in a direction away from top plate 40. Leg 31a has a bore 32a in the approximate center of leg 31a. Rear plate 30 has at least one member 33a extending perpendicular to front plate 30 at approximately ninety degrees and being parallel to top plate 40. Member 33a has a bore 34a in the approximate center of member 33a. A reinforced punch 35a is located in a bend 36a of the angle where member 33a extends. FIG. 2 illustrates the manner in which the members (23a, 23b, 33a, and 33b) extend away from the main part of the body 12. Top plate 40 has a large elliptical bore 41. In one preferred embodiment elliptical bore 41 is almost as large as top plate 40. A raised lip 42 surrounds the opening of elliptical bore 41, and is raised and extends away from the body 12.

In a preferred embodiment, body 12 will have 3 legs and 2 members on both the front plate 20 and the rear plate 30 for a total of 6 legs (21a, 21b, 21c, 32a, 32b, and 32c) and 4 members (23a, 23b, 33a, and 33b). FIG. 2 illustrates a top view of a preferred embodiment with members 23a, 23b, 33a, and 33b extending away from the main part of body 12.

FIGS. 5 and 6 illustrate strap 50. Strap 50 comprises a head 54 and a strap body 53 and an end 53 where head 54 is smaller than strap body 53. Head 54 has a notch 51. Strap 50 has an angled edge 55 between notch 51 and strap body 53. Strap 50 engages with body 12 by insertion in elliptical bore 41. Angled part 55 is sized and shaped to correspond to matingly engage with raised lip 42. FIG. 7 illustrates one embodiment of the anchor system for concrete construction fully assembled. Strap body 53 is welded to a plate (not illustrated) embedded into a concrete slab or a steel beam of a building.

The anchor system is used in the construction industry to strengthen the framework of a building and is used as a connector of various construction pieces in a commercial building that is built with concrete and steel beams. In one preferred embodiment, the anchor system is encased in concrete when the concrete is poured for the building. Often building walls are first poured and then lifted into place for the building. When the concrete is poured, it is common to have other support materials within the walls. FIG. 9 illustrates the use of the anchor system in concrete where the body is encased in concrete and the elliptical bore can be seen with the strap sticking out of the concrete structure. The strap may then be attached, for example, by soldering to the framework of a building or structure, to a steel beam, and/or a metal plate within another piece of concrete. In one embodiment, the strap used is a flat strap as illustrated in FIGS. 5-7. In another embodiment, illustrated in FIG. 8, the strap used is threaded on one end and that end is coupled to the body of the anchor system 10. FIG. 8 illustrates an embodiment where studs 61 are coupled to the bores (e.g., 34a) in the members (e.g., 33a) of the body 12 for added reinforcement when embedded in concrete.

In some structures it is advantages to run metal lines within the concrete as well and the anchor system 10 such that metal lines may be run through one or more of the bores (e.g., 22a) in the legs (e.g., 21a) and/or one or more of the bores (e.g., 34a) in the members (e.g., 33a) of the body.

In one embodiment, the anchor system 10, including the body 12 and the strap 53, is coated in a less corrosive finish, for example a J-finish.
