CROSS-REFERENCE TO RELATED APPLICATIONS / INCORPORATION BY REFERENCE
[0001] The present application is a continuation-in-part of U.S. patent application Ser. No. 18 / 239,627, filed on Aug. 29, 2023, and titled “REINFORCING BAR CAGE CONNECTORS AND METHODS OF CONSTRUCTING REINFORCING BAR CAGES.” The above referenced application is hereby incorporated herein by reference in its entirety.FIELD
[0002] The present disclosure relates to fabrication of concrete elements that include reinforcing bar cages. More specifically, the present disclosure relates to reinforcing bar cage connectors operable to secure reinforcing bar cages used in fabrication of concrete elements, and methods of constructing reinforcing bar cages used in fabrication of concrete elements.BACKGROUND
[0003] Concrete is a building material made from the combination of aggregate and a cement binder. A common form of concrete consists of Portland cement, mineral aggregates (for example, gravel and sand) and water. After mixing, the water reacts with the cement in a chemical process known as hydration, during which the water is absorbed by the cement, which hardens, binding the aggregates together and eventually creating a stone-like material. Concrete is used, for example, in pavement, building structures, foundations, roads, and bases for gates, fences and poles. Concrete is also used, for example, in concrete columns used in construction known as footings.
[0004] Concrete has high compressive strength, but low tensile strength. In other words, concrete can withstand axially directed pushing forces, but cannot withstand axially directed pulling forces. As a result, concrete elements subjected to tensile stresses are often reinforced with steel bars, known as reinforcing bar or rebar, which can aid in carrying tensile loads. Rebar is often formed from mild steel, and given ridges for better frictional adhesion to the concrete.
[0005] In practice, a reinforcing cage can be constructed out of rebar. A reinforcing cage can be constructed out of multiple pieces of rebar that are maintained relative to each other in conjunction with specific design requirements. Some examples of items that can influence the design requirements of a reinforcing cage include: the type of structure that is being fabricated, the size and weight of the structure, and the bearing capacity of the soil upon which the structure will rest.
[0006] Once a reinforcing cage is constructed, it can be inserted into a mold that can receive concrete. In one example, a mold can be a tube made of cardboard or other fibrous material. Examples of such tubes are the Sonotube® made by Sonoco Products Company and the Quik-Tube® made by the QUIKRETE® Companies.
[0007] Once a reinforcing cage is constructed and inserted into a mold, mixed concrete can be poured into the tube and allowed to harden. The result is a concrete element that includes a reinforcing cage that, as described above, can aid in carrying tensile loads.
[0008] Unfortunately, constructing a reinforcing cage can be time-consuming and cumbersome. For example, one method used to construct reinforcing cages utilizes pieces of wire to connect pieces of rebar in a desired configuration. However, one problem with such a method is that the resulting reinforcing cage is not very durable and can fall apart or lose desired dimensions when being moved or inserted into a mold. In another example, pieces of rebar that make up a reinforcing guide can be welded together. Such reinforcing guides are more durable than the ones held together by wires, however, they can be costly in terms of materials and labor.
[0009] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application.SUMMARY
[0010] Certain embodiments of the present technology provide reinforcing bar cage connectors and methods of constructing reinforcing bar cages, substantially as shown in and / or described in connection with at least one of the figures.

FIG. 4 depicts an enlarged view of the identified portion 4 of FIG. 3, in accordance with various embodiments.
[0035] Referring to FIGS. 1-4, a reinforcing bar cage 100 is shown. The reinforcing bar cage 100 comprises a reinforcing bar guide 110, a reinforcing bar rod 120, and a first embodiment of a reinforcing bar cage connector 130 securely fastening the reinforcing bar guide 110 to the reinforcing bar rod 120. As used herein, the term “reinforcing bar” is also referred to as “rebar” (e.g., rebar cage 100, rebar guide 110, rebar rod 120, rebar cage connector 130, and the like). Although the rebar cage 100 is shown having one rebar rod 120 attached to the rebar guide 110 by the rebar cage connector 130, any suitable number of rebar rods 120 may be fastened to rebar guide 110 by a corresponding number of rebar cage connectors 130. The rebar rods 120 may be evenly spaced or unevenly spaced around the rebar guide 110. Furthermore, any suitable number of rebar guides 110 may be secured to each rebar rod 120 by a corresponding number of rebar cage connectors 130. The rebar guides 110 may be evenly spaced or unevenly spaced along one or more of the rebar rods 120. For example, three (3) rebar guides 110 may be secured to four (4) rebar rods 120 using twelve (12) rebar cage connectors 130 to construct the rebar cage 100. As another example, five (5) rebar guides 110 may be secured to three (3) rebar rods 120 using fifteen (15) rebar cage connectors 130 to construct the rebar cage 100.
[0036] Although the rebar rod 120 is shown connected by the rebar cage connector 130 on an outside of the rebar guide 110, in various embodiments, the rebar rod 120 may additionally or alternatively be coupled by the rebar cage connector 130 to an inside of the rebar guide 110. Although the rebar guide 110 is illustrated as having an oval shape, in various embodiments, the rebar guide 110 may be any suitable shape, such as circular, square, triangular, rectangular, trapezoidal, or the like. For example, in other embodiments, the rebar guide 110 can be a straight element or an element with any number of bends or curves. As an example, in other embodiments, the shape of the rebar guide 110 can vary depending on the design requirements of the rebar guide 110. Although the rebar guide 110 and rebar rod 120 are both preferably made of rebar (i.e., reinforcing bar), in other embodiments, one or both of the rebar guide 110 and rebar rod 120 may not be made of rebar. For example, the rebar guide 110 and / or rebar rod 120 may be made of any strong and durable material. In various embodiments, the rebar cage connector 130 may be made of metal, such as hot dipped galvanized spring steel, high carbon steel, and / or any suitable material. In an exemplary embodiment, the rebar cage connector 130 may be coated with a rust-resistant material to increase durability and lifespan.
[0037] The rebar cage 100 is constructed by securing the rebar guide 110 to the rebar rod 120 via the rebar cage connector 130. FIG. 5 depicts a rear, side perspective view of the first embodiment of the exemplary reinforcing bar cage connector 130, in accordance with various embodiments. FIG. 6 depicts a front, side perspective view of the first embodiment of the exemplary reinforcing bar cage connector 130, in accordance with various embodiments. Referring to FIGS. 1-6, the rebar cage connector 130 comprises a base portion 131, a first (i.e., upper) tab 136, a second (i.e., lower) tab 138, and a hook portion 133. The first tab 136 extends from a first (i.e., top) end of the base portion 131 in a first direction forming a first obtuse angle between front sides of the base portion 131 and upper tab 136. The second tab 138 extends from a second (i.e., bottom) end of the base portion 131 in a second direction forming a second obtuse angle between front sides of the base portion 131 and lower tab 138. In various embodiments, the first and second obtuse angles may be the same angle or substantially the same angle (i.e., within 10 degrees). In an exemplary embodiment, the first and second directions are both angled away from the base portion 131 and towards a front side of the rebar cage connector 130.
[0038] The upper tab 136 comprises an upper tab opening 137. The upper tab opening 137 is provided through the upper tab 136 and through the top end portion of the base portion 131. The upper tab opening 137 extends between a central location of the upper tab 136 and the top end portion of the base portion 131. The lower tab 138 comprises a lower tab opening 139. The lower tab opening 139 is provided through the lower tab 138 and through the bottom end portion of the base portion 131. The lower tab opening 139 extends between a central location of the lower tab 138 and the bottom end portion of the base portion 131.
[0039] The upper tab opening 137 and lower tab opening 139 are configured to receive a same rebar rod 120 that extends through both openings 137, 139. In a representative embodiment, a rear side of the upper tab 136 and a rear side of the lower tab 138 are configured to simultaneously receive a compressive force to slightly bend the ends of the tabs 136, 138 towards each other, which slightly enlarges a size of the openings 137, 139 along a longitudinal axis through the openings 137, 139, and allows the rebar cage connector 130 to slide along the rebar rod 120 to a desired position on the rebar rod 120. For example, a user may use a thumb and finger to press the upper 136 and lower 138 tabs towards each other while sliding the rebar cage connector 130 along the rebar rod 120 to the desired position. The compressive force is released once the rebar cage connector 130 is positioned on the rebar rod 120. The end portions of the openings 137, 139 at the central locations of the tabs 136, 138 and at the top and bottom end portions of the base portion 131 are configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection once the compressive force is released from the upper 136 and lower 138 tabs. The deformation pattern 122 is protrusions (e.g., ribs or the like) on the rebar rod 120, which may be a helical pattern, V-shaped pattern, swirls, or any suitable pattern.
[0040] In various embodiments, the base portion 131 comprises a curvature. For example, a rear side (i.e., from which the hook portion 133 extends) of the base portion 131 may be slightly concave and a front side (i.e., opposite the hook portion 133) of the base portion 131 may be slightly convex. The compressive force provided on the rear sides of the upper 136 and lower 138 tabs may straighten and / or otherwise reduce an amount of curvature of the base portion 131, such that a size of the openings 137, 139 along a longitudinal axis through the openings 137, 139 is increased to allow the rebar cage connector 130 and rebar rod 120 to slide with respect to each other. The curvature of the base portion 131 biases the uppermost end of the upper tab 136 and the lowermost end of the lower tab 138 away from each other such that the size of the openings 137, 139 along the longitudinal axis through the openings 137, 139 is decreased when the compressive force is released. The bias force provided by the curvature of the base portion 131 increases the force of the engagement between the two end portions of each of the openings 137, 139 and the deformation pattern 122 on the rebar rod 120 to provide the secure connection of the rebar cage connector 130 on the rebar rod 120.
[0041] The hook portion 133 of the rebar cage connector 130 extends from a rear side of the base portion 131 of the rebar cage connector 130 and curls up towards the upper tab 136. In various embodiments, the hook portion 133 may be formed from material of the base portion 131, which leaves a base opening 132 in the base portion 131. The hook portion 133 comprises a first end attached and / or integrated with the base portion 131 and a second end opposite the first end. The second end may comprise a flared end portion 135 configured to assist in receiving a rebar guide 110. In various embodiments, an inside surface of the hook portion 133 may comprise punch grips 137. The punch grips 137 are protrusions (e.g., dimples, indents, or the like) configured to engage a deformation pattern 112 on the rebar guide 110 to provide a strong and stable connection. The deformation pattern 112 is protrusions (e.g., ribs or the like) on the rebar guide 110, which may be a helical pattern, V-shaped pattern, swirls, or any suitable pattern.
[0042] In operation, the rebar guide 110 may be pressed between the flared end 135 of the hook portion and the rear side of the base portion 131. The pressure pushes the flared end 135 away from the rear side of the base portion 131 such that the rebar guide 110 passes through the opening between the flared end 135 and the rear side of the base portion 131 and snaps into the hook portion 133. The flared end 135 is biased towards the rear side of the base portion 131 such that the flared end moves back towards the rear side of the base portion 131 once the rebar guide 110 moves through the opening between the flared end 135 and the rear side of the base portion 131 and into the hook portion 133. The punch grips 137 engage the deformation pattern 112 on the rebar guide 110 once the rebar guide enters the hook portion 133 to provide the secure connection between the hook portion 133 of the rebar cage connector 130 and the rebar guide 110. The inside surface of the hook portion 133 and the rear side of the base portion are configured to cover a majority of a circumference of the rebar guide 110 when the rebar guide is positioned within the hook portion 133 of the rebar cage connector 130.
[0043] As shown in FIGS. 1-4, the hook portion 133 is configured to engage and secure a horizontal rebar guide 110 on a first (i.e. rear) side of the rebar cage connector 130 while the openings 137, 139 in the tabs 136, 138 are configured to simultaneously engage and secure a vertical rebar rod 120 on a second (i.e., front), opposite side of the rebar cage connector 130. Accordingly, the rebar cage connector 130 is a device used for building a rebar cage 100, a structure used to reinforce concrete. The rebar cage connector 130 may be made of metal, such as hot dipped galvanized spring steel, high carbon steel, or any suitable material, and coated with rust-resistant material to increase its durability and lifespan. In various embodiments, the rebar cage connector 130 may be a single, integrated component. Additionally and / or alternatively, the upper tab 136, lower tab 138, and / or hook portion 133 may be fixedly attached to the base portion 131.
[0044] FIG. 7 is a flow chart 200 illustrating exemplary steps 202-212 that may be utilized for constructing reinforcing bar cages 100 with the first embodiment of the exemplary reinforcing bar cage connector 130 of FIGS. 1-6, in accordance with various embodiments. Referring to FIG. 7, there is shown a flow chart 200 comprising exemplary steps 202 through 212. Certain embodiments may omit one or more of the steps, and / or perform the steps in a different order than the order listed, and / or combine certain of the steps discussed below. For example, some steps may not be performed in certain embodiments. As a further example, certain steps may be performed in a different temporal order, including simultaneously, than listed below.
[0045] At step 202, an upper tab 136 and a lower tab 138 of a rebar cage connector 130 are simultaneously pressed towards each other. For example, a user may place a thumb and finger on rear sides of the upper 136 and lower 138 tabs and provide a compressive force on the upper 136 and lower 138 tabs. The compressive force causes the ends of the tabs 136, 138 to bend towards each other, which enlarges a size of the openings 137, 139 along a longitudinal axis through the openings 137, 139. In various embodiments, a base portion 131 of the rebar cage connector 130 may have a curvature that is decreased and / or straightened when the compressive force is applied to the tabs 136, 138.
[0046] At step 204, a rebar rod 120 is inserted through an upper tab opening 137 of the upper tab 136 and a lower tab opening 139 of the lower tab 138 of the rebar cage connector 130. For example, a user may slide the rebar cage connector 130 onto the rebar rod 120 by inserting the rebar rod 120 through the openings 137, 139 in the tabs 136, 138 while applying the compressive force to the tabs 136, 138.
[0047] At step 206, the rebar cage connector 130 is manipulated to a desired position on the rebar rod 120, and the upper 136 and lower 138 tabs of the rebar cage connector 130 are released. For example, the rebar cage connector 130 may be slid along a longitudinal axis of the rebar rod 120 to a desired location on the rebar rod 120. The upper 136 and lower 138 tabs are released when the rebar cage connector 130 is at the desired position on the rebar rod 120. The release of the compressive force causes the size of the openings 137, 139 along the longitudinal axis through the openings 137, 139 to decrease. The end portions of the openings 137, 139 at the central locations of the tabs 136, 138 and at the top and bottom end portions of the base portion 131 are configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection once the compressive force is released from the upper 136 and lower 138 tabs. In various embodiments, a bias force provided by the curvature of the base portion 131 increases the force of the engagement between the two end portions of each of the openings 137, 139 and the deformation pattern 122 on the rebar rod 120 to provide the secure connection of the rebar cage connector 130 on the rebar rod 120.
[0048] At step 208, a rebar guide 110 is inserted into a hook portion 133 of the rebar cage connector 130. For example, a rebar guide 110 may be pressed between a flared end 135 of the hook portion 133 and the rear side of the base portion 131. The pressure pushes the flared end 135 away from the rear side of the base portion 131 such that the rebar guide 110 passes through the opening between the flared end 135 and the rear side of the base portion 131 and snaps into the hook portion 133. The flared end 135 is biased towards the rear side of the base portion 131 such that the flared end moves back towards the rear side of the base portion 131 once the rebar guide 110 moves through the opening between the flared end 135 and the rear side of the base portion 131 and into the hook portion 133. Punch grips 137 on an inside surface of the hook portion 133 engage a deformation pattern 112 on the rebar guide 110 once the rebar guide 110 enters the hook portion 133 to provide the secure connection between the hook portion 133 of the rebar cage connector 130 and the rebar guide 110.
[0049] At step 210, if additional rebar rods 120 or rebar guides 110 are being used to construct the rebar cage 100, steps 202 through 208 are repeated using an additional rebar cage connector 130 for each connection point between the rebar guide(s) 110 and rebar rod(s) 120. For example, if the rebar cage 100 comprises three (3) rebar guides 110 and four (4) rebar rods 120, twelve (12) rebar cage connectors 130 may be implemented to build the rebar cage 100. If no additional rebar rods 120 or rebar guides 110 are being used to construct the rebar cage 100, the process proceeds to step 212 where the rebar cage 100 is complete. Once a rebar cage 100 is complete, it can be placed in a mold. The mold can then be filled with mixed concrete. After the concrete sets, the mold can be removed and a concrete element that contains the reinforcing bar cage 100 remains.
[0050] FIG. 8 depicts a front, top perspective view of an exemplary reinforcing bar cage 300 having a reinforcing bar guide 110 securely coupled to a reinforcing bar rod 120 by a second embodiment of a reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 9 depicts an enlarged view of the identified portion 6 of FIG. 8, in accordance with various embodiments. FIG. 10 depicts a rear, top perspective view of an exemplary reinforcing bar cage 300 having a reinforcing bar guide 110 securely coupled to a reinforcing bar rod 120 by the second embodiment of the reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 11 depicts an enlarged view of the identified portion 8 of FIG. 10, in accordance with various embodiments.
[0051] Referring to FIGS. 8-11, a reinforcing bar cage 300 is shown. The reinforcing bar cage 300 comprises a reinforcing bar guide 110, a reinforcing bar rod 120, and a second embodiment of a reinforcing bar cage connector 330 securely fastening the reinforcing bar guide 110 to the reinforcing bar rod 120. Although the rebar cage 300 is shown having one rebar rod 120 attached to the rebar guide 110 by the rebar cage connector 330, any suitable number of rebar rods 120 may be fastened to rebar guide 110 by a corresponding number of rebar cage connectors 330. The rebar rods 120 may be evenly spaced or unevenly spaced around the rebar guide 110. Furthermore, any suitable number of rebar guides 110 may be secured to each rebar rod 120 by a corresponding number of rebar cage connectors 330. The rebar guides 110 may be evenly spaced or unevenly spaced along one or more of the rebar rods 120. For example, three (3) rebar guides 110 may be secured to four (4) rebar rods 120 using twelve (12) rebar cage connectors 330 to construct the rebar cage 300. As another example, five (5) rebar guides 110 may be secured to three (3) rebar rods 120 using fifteen (15) rebar cage connectors 330 to construct the rebar cage 300.
[0052] Although the rebar rod 120 is shown connected by the rebar cage connector 330 on an outside of the rebar guide 110, in various embodiments, the rebar rod 120 may additionally or alternatively be coupled by the rebar cage connector 330 to an inside of the rebar guide 110. The rebar guide 110 and rebar rod 120 of FIGS. 8-11 share various characteristics with the rebar guide 110 and rebar rod 120 as explained above with respect to FIGS. 1-4, for example, with regard to the various shapes, materials, and the like discussed previously. In various embodiments, the rebar cage connector 330 may be made of metal, such as hot dipped galvanized spring steel, high carbon steel, and / or any suitable material. In an exemplary embodiment, the rebar cage connector 330 may be coated with a rust-resistant material to increase durability and lifespan.
[0053] The rebar cage 300 is constructed by securing the rebar guide 110 to the rebar rod 120 via the rebar cage connector 330. FIG. 12 depicts a rear, side perspective view of the second embodiment of the exemplary reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 13 depicts a front, side perspective view of the second embodiment of the exemplary reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 14 depicts a side view of the second embodiment of the exemplary reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 15 depicts a rear view of the second embodiment of the exemplary reinforcing bar cage connector 330, in accordance with various embodiments. FIG. 16 depicts a front view of the second embodiment of the exemplary reinforcing bar cage connector 330, in accordance with various embodiments. Referring to FIGS. 8-16, the rebar cage connector 330 comprises a first (i.e., front) side 343, a second (i.e., back) side 344, a base portion 331, a first (i.e., upper) tab 336, a second (i.e., lower) tab 338, and a hook portion 333. The first tab 336 extends from a first (i.e., top) end of the base portion 331 in a first direction forming a first obtuse angle between front sides 343 of the base portion 331 and upper tab 336. The base portion 331 and upper tab 336 meet at a first (i.e., upper) bend 345, which provides the first obtuse angle.
[0054] The second tab 338 extends from a second (i.e., bottom) end of the base portion 331 in a second direction forming a second obtuse angle between front sides 343 of the base portion 331 and lower tab 338. The base portion 331 and lower tab 338 meet at a second (i.e., lower) bend 346, which provides the second obtuse angle. In various embodiments, the first and second obtuse angles may be the same angle or substantially the same angle (i.e., within 10 degrees). In an exemplary embodiment, the first and second directions are both angled away from the base portion 331 and towards a front side 343 of the rebar cage connector 330.
[0055] The upper tab 336 comprises an upper tab opening 337. The upper tab opening 337 is provided through the upper tab 336 and through the top end portion of the base portion 331. The upper tab opening 337 extends between a central location of the upper tab 336 and the top end portion of the base portion 331. In a preferred embodiment, a portion of the upper tab opening 337 extends higher than the upper bend 345 and a portion of the upper tab opening 337 extends lower than the upper bend 345. The upper bend 345 defines the interface between the base portion 331 and the upper tab 336. The upper tab 336 comprises an upper tab side aperture 340 providing access to the upper tab opening 337.
[0056] In contrast with the first embodiment of the rebar cage connector 130 described above with reference to FIGS. 1-7, a portion of the base portion 131 and upper tab 136 on one lateral side adjacent the upper tab opening 137 is removed to provide the upper tab side aperture 340 of the rebar cage connector 330 of the second embodiment. The upper tab side aperture 340 allows the rebar cage connector 330 of the second embodiment to be attached to a rebar rod 120 without having to insert an end of the rebar rod 120 through the upper tab opening 137 and sliding the rebar cage connector 130 along the rebar rod 120 to a desired attachment location as is done using the rebar cage connector 130 of the first embodiment. Accordingly, the rebar cage connector 330 of the second embodiment having the upper tab side aperture 340 simplifies the attachment process of the rebar cage connector 330 to the rebar rod 120 in comparison to the rebar cage connector 130 of the first embodiment.
[0057] Referring again to FIGS. 8-16, the resulting shape of the upper tab 336 and the top portion of the base portion 331 resembles a “C” shape with the top portion of the base portion 331 forming an “L” shape and the upper tab 336 forming an “r” shape that extends from the top of the vertical portion of the “L” shape. In a preferred embodiment, a portion of the upper tab 336 facing the upper tab opening 337 comprises rebar engagement teeth 342 configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection.
[0058] The lower tab 338 comprises a lower tab opening 339. The lower tab opening 339 is provided through the lower tab 338 and through the bottom end portion of the base portion 331. The lower tab opening 339 extends between a central location of the lower tab 338 and the bottom end portion of the base portion 331. In a preferred embodiment, a portion of the lower tab opening 339 extends lower than the lower bend 346 and a portion of the lower tab opening 339 extends higher than the lower bend 346. The lower bend 346 defines the interface between the base portion 331 and the lower tab 338. The lower tab 338 comprises a lower tab side aperture 341 providing access to the lower tab opening 339.
[0059] In contrast with the first embodiment of the rebar cage connector 130 described above with reference to FIGS. 1-7, a portion of the base portion 131 and lower tab 138 on one lateral side adjacent the lower tab opening 139 is removed to provide the lower tab side aperture 341 of the rebar cage connector 330 of the second embodiment. The lower tab side aperture 341 allows the rebar cage connector 330 of the second embodiment to be attached to a rebar rod 120 without having to insert an end of the rebar rod 120 through the lower tab opening 139 and sliding the rebar cage connector 130 along the rebar rod 120 to a desired attachment location as is done using the rebar cage connector 130 of the first embodiment. Accordingly, the rebar cage connector 330 of the second embodiment having the lower tab side aperture 341 simplifies the attachment process of the rebar cage connector 330 to the rebar rod 120 in comparison to the rebar cage connector 130 of the first embodiment.
[0060] Referring again to FIGS. 8-16, the resulting shape of the lower tab 336 and the bottom portion of the base portion 331 resembles a “C” shape with the bottom portion of the base portion 331 forming an “r” shape and the lower tab 338 forming an “L” shape (or “J” shape flipped along the long edge) that extends from the bottom of the vertical portion of the “r” shape. In a preferred embodiment, a portion of the lower tab 338 facing the lower tab opening 339 comprises rebar engagement teeth 342 configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection. Although the upper tab side aperture 340 and lower tab side aperture 341 are shown on a right side of the rebar cage connector 330 when viewed from the front 343, the upper tab side aperture 340 and lower tab side aperture 341 may alternatively be on a left side of the rebar cage connector 330 when viewed from the front 343.
[0061] The upper tab opening 337 and lower tab opening 339 are configured to receive a same rebar rod 120 through the upper tab side aperture 340 and lower tab side aperture 341 such that the rebar rod 120 extends through both openings 337, 339. In a representative embodiment, a rear side 344 of the upper tab 336 and a rear side 344 of the lower tab 338 are configured to simultaneously receive a compressive force to slightly bend the ends of the tabs 336, 338 towards each other, which slightly enlarges a size of the openings 337, 339 along a longitudinal axis through the openings 337, 339, and allows the rebar rod 120 to be inserted into the openings 337, 339 through the upper tab side aperture 340 and lower tab side aperture 341 at a desired position on the rebar rod 120. For example, a user may use a thumb and finger to press the upper 336 and lower 338 tabs towards each other while inserting the rebar rod 120 through the apertures 340, 341 and into the openings 337, 339 at the desired position. The compressive force is released once the rebar cage connector 330 is positioned on the rebar rod 120. The end portions of the openings 337, 339 at the central locations of the tabs 336, 338 and at the top and bottom end portions of the base portion 331 are configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection once the compressive force is released from the upper 336 and lower 338 tabs. The deformation pattern 122 is protrusions (e.g., ribs or the like) on the rebar rod 120, which may be a helical pattern, V-shaped pattern, swirls, or any suitable pattern. In a preferred embodiment, the portion of the upper tab 336 facing the upper tab opening 337 and the portion of the lower tab 338 facing the lower tab opening 339 comprise rebar engagement teeth 342 configured to engage the deformation pattern 122 on the rebar rod 120 increasing the reliability of the connection between the rebar cage connector 330 and the rebar rod 120.
[0062] In various embodiments, the base portion 331 comprises a curvature. For example, a rear side 344 (i.e., from which the hook portion 333 extends) of the base portion 331 may be concave and a front side 343 (i.e., opposite the hook portion 333) of the base portion 331 may be convex. The compressive force provided on the rear sides 344 of the upper 336 and lower 338 tabs may straighten and / or otherwise reduce an amount of curvature of the base portion 331, such that a size of the openings 337, 339 along a longitudinal axis through the openings 337, 339 is increased to allow the rebar rod 120 to be inserted into the openings 337, 339 through the upper tab side aperture 340 and lower tab side aperture 341 at a desired position on the rebar rod 120. The curvature of the base portion 331 biases the uppermost end of the upper tab 336 and the lowermost end of the lower tab 338 away from each other such that the size of the openings 337, 339 along the longitudinal axis through the openings 337, 339 is decreased when the compressive force is released. The bias force provided by the curvature of the base portion 331 increases the force of the engagement between the two end portions of each of the openings 337, 339 and the deformation pattern 122 on the rebar rod 120 to provide the secure connection of the rebar cage connector 330 on the rebar rod 120.
[0063] The hook portion 333 of the rebar cage connector 330 extends from a rear side 344 of the base portion 331 of the rebar cage connector 330 and curls up towards the upper tab 336. In various embodiments, the hook portion 333 may be formed from material of the base portion 331, which leaves a base opening 332 in the base portion 331. The hook portion 333 comprises a first end attached and / or integrated with the base portion 331 and a second end opposite the first end. The second end may comprise a flared end portion 335 configured to assist in receiving a rebar guide 110. In various embodiments, an inside surface of the hook portion 333 may comprise punch grips 337. The punch grips 337 are protrusions (e.g., dimples, indents, or the like) configured to engage a deformation pattern 112 on the rebar guide 110 to provide a strong and stable connection. The deformation pattern 112 is protrusions (e.g., ribs or the like) on the rebar guide 110, which may be a helical pattern, V-shaped pattern, swirls, or any suitable pattern.
[0064] In operation, the rebar guide 110 may be pressed between the flared end 335 of the hook portion and the rear side 344 of the base portion 331. The pressure pushes the flared end 335 away from the rear side of the base portion 331 such that the rebar guide 110 passes through the opening between the flared end 335 and the rear side of the base portion 331 and snaps into the hook portion 333. The flared end 335 is biased towards the rear side of the base portion 331 such that the flared end moves back towards the rear side of the base portion 331 once the rebar guide 110 moves through the opening between the flared end 335 and the rear side 344 of the base portion 331 and into the hook portion 333. The punch grips 337 engage the deformation pattern 112 on the rebar guide 110 once the rebar guide enters the hook portion 333 to provide the secure connection between the hook portion 333 of the rebar cage connector 330 and the rebar guide 110. The inside surface of the hook portion 333 and the rear side of the base portion are configured to cover a majority of a circumference of the rebar guide 110 when the rebar guide is positioned within the hook portion 333 of the rebar cage connector 330.
[0065] As shown in FIGS. 8-11, the hook portion 333 is configured to engage and secure a horizontal rebar guide 110 on a first 344 (i.e. rear) side of the rebar cage connector 330 while the openings 337, 339 in the tabs 336, 338 are configured to simultaneously engage and secure a vertical rebar rod 120 on a second 343 (i.e., front), opposite side of the rebar cage connector 330. Accordingly, the rebar cage connector 330 is a device used for building a rebar cage 300, a structure used to reinforce concrete. The rebar cage connector 330 may be made of metal, such as hot dipped galvanized spring steel, high carbon steel, or any suitable material, and coated with rust-resistant material to increase its durability and lifespan. In various embodiments, the rebar cage connector 330 may be a single, integrated component. Additionally and / or alternatively, the upper tab 336, lower tab 338, and / or hook portion 333 may be fixedly attached to the base portion 331.
[0066] FIG. 18 is a flow chart 400 illustrating exemplary steps 402-412 that may be utilized for constructing reinforcing bar cages 300 with the second embodiment of the exemplary reinforcing bar cage connector 330 of FIGS. 8-17, in accordance with various embodiments. Referring to FIG. 18, there is shown a flow chart 400 comprising exemplary steps 402 through 412. Certain embodiments may omit one or more of the steps, and / or perform the steps in a different order than the order listed, and / or combine certain of the steps discussed below. For example, some steps may not be performed in certain embodiments. As a further example, certain steps may be performed in a different temporal order, including simultaneously, than listed below.
[0067] At step 402, a rebar cage connector 330 is positioned at a desired position adjacent a rebar rod 120. FIG. 17 depicts a side view of the second embodiment of the exemplary reinforcing bar cage connector at a first time 330a prior to attachment to the rebar rod 120 and at a second time 330b after attachment to the rebar rod 120, in accordance with various embodiments. Referring to FIGS. 17-18, the rebar cage connector at the first time 330a is shown adjacent to a rebar rod 120 at a desired position for attachment. The rebar cage connector at the first time 330a comprises a base portion 331a, upper 336a and lower 338a tabs extending from the base portion 331a at upper 345a and lower 346a bends, and a hook portion 333a having a flared end 335a.
[0068] At step 404, an upper tab 336 and a lower tab 338 of the rebar cage connector 330 are simultaneously pressed towards each other while the rebar rod 120 is inserted through an upper tab side aperture 340 into an upper tab opening 337 of the upper tab 336 and through a lower tab side aperture 341 into a lower tab opening 339 of the lower tab 338 of the rebar cage connector 330. For example, a user may place a thumb and finger on rear sides of the upper 336 and lower 338 tabs and provide a compressive force on the upper 336 and lower 338 tabs. The base portion 331 of the rebar cage connector 330 comprises a curvature that is decreased and / or straightened when the compressive force is applied to the tabs 336, 338. The compressive force causes the ends of the tabs 336, 338 to bend towards each other, which enlarges a size of the openings 337, 339 along a longitudinal axis through the openings 337, 339. The rebar rod 120 is inserted into the openings 337, 339 through the upper tab side aperture 340 and lower tab side aperture 341 at the desired position on the rebar rod 120. Referring again to FIG. 17, arrows are shown where compressive force may be applied to the upper 336a and lower 338a tabs. The rebar cage connector at the second time 330b is shown after the upper 336b and lower 338b tabs are compressed and the rebar rod 120 is inserted into the openings 337, 339 via the apertures 340, 341. The rebar cage connector at the second time 330b comprises a base portion 331b, upper 336b and lower 338b tabs extending from the base portion 331b at upper 345b and lower 346b bends, and a hook portion 333b having a flared end 335b.
[0069] At step 406, the upper 336 and lower 338 tabs of the rebar cage connector 330 are released. For example, the upper 336 and lower 338 tabs are released when the rebar cage connector 330 is at the desired position on the rebar rod 120. The release of the compressive force causes the size of the openings 337, 339 along the longitudinal axis through the openings 337, 339 to decrease. The end portions of the openings 337, 339 at the central locations of the tabs 336, 338 and at the top and bottom end portions of the base portion 331 are configured to engage a deformation pattern 122 on the rebar rod 120 to provide a strong and stable connection once the compressive force is released from the upper 336 and lower 338 tabs. In a preferred embodiment, the portion of the upper tab 336 facing the upper tab opening 337 and the portion of the lower tab 338 facing the lower tab opening 339 comprise rebar engagement teeth 342 configured to engage the deformation pattern 122 on the rebar rod 120 increasing the reliability of the connection between the rebar cage connector 330 and the rebar rod 120. In various embodiments, a bias force provided by the curvature of the base portion 331 increases the force of the engagement between the two end portions of each of the openings 337, 339 and the deformation pattern 122 on the rebar rod 120 to further enhance the secure connection of the rebar cage connector 330 on the rebar rod 120.
[0070] At step 408, a rebar guide 110 is inserted into a hook portion 333 of the rebar cage connector 330. For example, a rebar guide 110 may be pressed between a flared end 335 of the hook portion 333 and the rear side 344 of the base portion 131. The pressure pushes the flared end 335 away from the rear side 344 of the base portion 331 such that the rebar guide 110 passes through the opening between the flared end 335 and the rear side 344 of the base portion 331 and snaps into the hook portion 333. The flared end 335 is biased towards the rear side 344 of the base portion 331 such that the flared end 335 moves back towards the rear side 344 of the base portion 331 once the rebar guide 110 moves through the opening between the flared end 335 and the rear side 344 of the base portion 331 and into the hook portion 333. Punch grips 337 on an inside surface of the hook portion 333 engage a deformation pattern 112 on the rebar guide 110 once the rebar guide 110 enters the hook portion 333 to provide the secure connection between the hook portion 333 of the rebar cage connector 330 and the rebar guide 110.
[0071] At step 410, if additional rebar rods 120 or rebar guides 110 are being used to construct the rebar cage 300, steps 402 through 408 are repeated using an additional rebar cage connector 330 for each connection point between the rebar guide(s) 110 and rebar rod(s) 120. For example, if the rebar cage 300 comprises three (3) rebar guides 110 and four (4) rebar rods 120, twelve (12) rebar cage connectors 330 may be implemented to build the rebar cage 300. If no additional rebar rods 120 or rebar guides 110 are being used to construct the rebar cage 300, the process proceeds to step 412 where the rebar cage 300 is complete. Once a rebar cage 300 is complete, it can be placed in a mold. The mold can then be filled with mixed concrete. After the concrete sets, the mold can be removed and a concrete element that contains the reinforcing bar cage 300 remains.
